Comparison of the air kerma standards of the IAEA and the BIPM in mammography x-rays  

NASA Astrophysics Data System (ADS)

The Dosimetry Laboratory of the International Atomic Energy Agency (IAEA), Seibersdorf, Austria, calibrates reference standards in mammography x-ray beams for IAEA/WHO SSDL Network members (more than 80 laboratories worldwide). As a signatory of the Mutual Recognition Arrangement (CIPM MRA), the IAEA laboratory maintains a Quality Management System (QMS) complying with ISO 17025 and requires updated 'supporting evidence' for its dosimetry calibration and measurement capabilities (CMC), first published in Appendix C of the CIPM MRA key comparison database in 2007. For this purpose, an indirect comparison has been made between the air kerma standards of the IAEA and the Bureau International des Poids et Mesures (BIPM) in the mammography x-ray range from 25 kV to 35 kV, using as transfer instruments two thin-window parallel-plate ionization chambers belonging to the IAEA. The IAEA and BIPM standards for mammography x-rays are shown to be in agreement within the standard uncertainty of the comparison of 5.5 parts in 103. This agreement can be used to support the calibration and measurements capabilities of the IAEA listed in Appendix C of the key comparison database. Main text.

Objectives and Current Status of the IAEA Network of Centers of Excellence: Training in and Demonstration of Waste Disposal Technologies in Underground Research Laboratories  

SciTech Connect

Underground Research Laboratories (URLs) to develop and demonstrate technologies for the safe geologic disposal of radioactive wastes have been established for national purposes by several Member States of the International Atomic Energy Agency (IAEA). Under the auspices of the IAEA, nationally developed URLs and associated research institutions are being offered for use by other nations. These facilities form a Network of Centers of Excellence for training in and development of waste disposal technologies. Experience gained in the operation of the facilities, and through associated experimentation and demonstrations, will be transferred to participating Member States through hands-on work at the facilities. The Network consists of Network Members and Network Participants who share co-operative activities. Network Members are owners of facilities who have offered them to be part of the Network. At this time there are eight Members consisting of six underground facilities, a laboratory, and a university. Network Participants can potentially come from any interested IAEA Member State having spent nuclear fuel for disposal, with or without an established program for geologic disposal. There are presently about 15 Network Participants. A significant Network activity beginning in 2003 will be a Coordinated Research Project (CRP) on characterization and evaluation of swelling clays for use in engineered barrier systems of geologic repositories. At the end of this project, every involved Member State should be able to identify and characterize a swelling clay that is suitable for use in a geologic repository. As the Network grows, additional CRPs to be carried out in the Underground Research Facilities of the Network Members will be defined.

Intercomparison of radon and decay product measurements in an underground mine and EPA Radon Laboratory: a study organized by the IAEA International Radon Metrology Programme. International Atomic Energy Agency.  

PubMed

The International Atomic Energy Agency (IAEA) in Vienna and the European Union (EU) in Bruxelles formed the "International Radon Metrology Programme" (IRMP, scientific secretary: F. Steinhäusler, University of Salzburg, Austria). The IRMP is designed to assess and foster the improvement of radon and decay product measurements that are made around the world. Within the framework of the IRMP, the U.S. Environmental Protection Agency Radiation and Indoor Environments National Laboratory (EPA) in Las Vegas, Nevada, organized jointly with the U.S. Bureau of Mines an international intercomparison exercise at a former uranium mine (Twilight Mine, Colorado) and the EPA Radon Laboratory. The main objective of this exercise was to compare radon and radon decay product instruments under both well-controlled as well as widely fluctuating exposure conditions. The laboratory exposures occurred under relatively steady radon and decay product conditions, with a moderate equilibrium ratio, while the conditions in the mine fluctuated greatly and the equilibrium ratio was low. An additional purpose of the exercise was to provide a forum for manufacturers and measurement organizations worldwide to exchange information and plan improvements in their operations and calibration programs. Altogether 19 organizations from seven countries intercomparing 32 different radon and radon decay product instruments participated in this exercise. This paper summarizes the results from the analysis of the experimental data obtained in the Bureau of Mines Twilight Mine in July of 1994, as well as the results from the EPA Radon laboratory in August of 1994.

Reference dosimeter system of the iaea  

NASA Astrophysics Data System (ADS)

Quality assurance programmes must be in operation at radiation processing facilities to satisfy national and international Standards. Since dosimetry has a vital function in these QA programmes, it is imperative that the dosimetry systems in use at these facilities are well calibrated with a traceability to a Primary Standard Dosimetry Laboratory. As a service to the Member States, the International Atomic Energy Agency operates the International Dose Assurance Service (IDAS) to assist in this process. The transfer standard dosimetry system that is used for this service is based on ESR spectrometry. The paper describes the activities undertaken at the IAEA Dosimetry Laboratory to establish the QA programme for its reference dosimetry system. There are four key elements of such a programme: quality assurance manual; calibration that is traceable to a Primary Standard Dosimetry Laboratory; a clear and detailed statement of uncertainty in the dose measurement; and, periodic quality audit.

TECHNOLOGY ROADMAPPING FOR IAEA SEALS.  

SciTech Connect

In the fall of 2002, the U.S. Support Program (USSP) initiated an effort to define a strategy or ''roadmap'' for future seals technologies and to develop a generalized process for planning safeguards equipment development, which includes seals and other safeguards equipment. The underlying objectives of the USSP include becoming more proactive than reactive in addressing safeguards equipment needs, helping the IAEA to maintain an inventory of cost-effective, reliable, and effective safeguards equipment, establishing a long-term planning horizon, and securing IAEA ownership in the process of effective requirements definition and timely transitioning of new or improved systems for IAEA use. At an initial workshop, seals, their functions, performance issues, and future embodiments were discussed in the following order: adhesive seals, metal seals, passive and active loop seals, ultrasonic seals, tamper indicating enclosures (including sample containers, equipment enclosures, and conduits). Suggested improvements to these technologies focused largely on a few themes: (1) The seals must be applied quickly, easily, and correctly; (2) Seals and their associated equipment should not unduly add bulk or weight to the inspectors load; (3) Rapid, in-situ verifiability of seals is desirable; and (4) Seal systems for high risk or high value applications should have two-way, remote communications. Based upon these observations and other insights, the participants constructed a skeletal approach for seals technology planning. The process begins with a top-level review of the fundamental safeguards requirements and extraction of required system features, which is followed by analysis of suitable technologies and identification of technology gaps, and finally by development of a planning schedule for system improvements and new technology integration. Development of a comprehensive procedure will require the partnership and participation of the IAEA. The presentation will include a description of the roadmapping approach developed for safeguards technologies and an overview of the initial seals workshop results.

Development of an IAEA Training Course for Future U.S. Inspectors  

SciTech Connect

U.S. citizens currently make up only 12% of the positions held in the IAEA’s Department of Safeguards. While the United States has maintained a high level of support for the Agency over the duration of its history, the number of American inspectors currently in the field does not reflect this level of involvement. As a result, the National Nuclear Security Administration’s Office of International Relations, as part of the Next Generation Safeguards Initiative (NGSI) mission, has tasked Idaho National Laboratory (INL) to develop a rigorous two week hands-on training program to encourage and operationally acclimatize U.S. Citizens who are interested in applying for IAEA inspector positions using IAEA authorized equipment at INL. Idaho National Laboratory is one-of-a-kind in its ability to train IAEA inspectors by including training at nuclear facilities on site and includes, for example, direct measurement of an active spent fuel storage cooling pond. This accredited course will introduce and train attendees on the major IAEA systems used in collecting nuclear safeguards data and performing safeguards inspections. Unique in the United States, these classes will give attendees direct hands-on training and will address equipment purpose, function, operating principles, application, and troubleshooting, based upon what would be expected of an IAEA Safeguards Inspector in the field and in the office. Upon completion, U.S. applicants will be better qualified to pursue a position in the IAEA Department of Safeguards Operational Divisions. In support, INL has recently established a new laboratory space to house state of the art nuclear safeguards instrumentation. Currently, equipment installed in the laboratory space includes attended systems: 3DLR (3-D Imaging Laser) for design information verification, a Digital Cerenkov Viewing Device for measurement of spent fuel, HM-5 handheld radiation detectors, quantitative neutron and gamma systems; unattended monitoring systems including: NGAM and MiniGRAND radiation systems and a DMOS camera system, and VACOSS/EOSS Optical Sealing Systems..

A brief history of NDA at the IAEA.  

SciTech Connect

Nearly 30 years ago, the first portable nondestructive assay instrument, a SAM-II, was brought to Vienna for IAEA consideration. This initial foray into the usage of nondestructive assay (NDA) as an independent assessment tool has materialized into one of the important tools for IAEA inspections. NDA instruments have several inherent advantages for inspectors; their measurements generate no radioactive waste, provide immediate answers, do not require specialized operators, and can be either taken to the items to be measured (portable instruments), or the items for measurement can be brought to the instruments, such as can be applied in on-site IAEA laboratories or off-site IAEA lab at Siebersdorf. The SAM-II was a small, lightweight, battery-powered, gamma-ray instrument used for uranium enrichment measurements. It was also found to be usehl for locating nuclear material, distinguishing between uranium and plutonium, and determining the active length of items like fuel pins. However it was not well suited for determining the amount of bulk material present, except for small containers of low-density materials. A 6-sided neutron coincidence counter, easily disassembled so it could be shipped and carried by airplane, was developed for bulk measurements of plutonium. The HLNCC (High Level Neutron Coincidence Counter) was immediately useful for quantitative measurements of pure plutonium oxide. However, the IAEA had to make a trade-off between the ease of use of NDA instruments on-site, and the problems of obtaining small samples for shipment to an independent lab for more accurate analysis. NDA does not create radioactive waste, so as waste handling has become more cautious and more regulated, NDA looks better and better. After acceptance of NDA by the IAEA for routine use, the follow-up question was naturally, 'How much better can this measurement be made?' The Program for Technical Assistance to IAEA Safeguards (POTAS) supported multiple and varied efforts in this direction, such as improving both the plutonium isotopic distribution measurement and the multiplicity counter, so that the assays can be performed on any plutonium samples instead of only pure oxides. Advances have also been made on uranium bulk measurements by the development of the active well coincidence counter. Meanwhile, several large bulk-handling facilities have been coming on line under IAEA safeguards. These facilities require full-time inspectors to be present whenever the plant is operating. The IAEA requested help so that measurements can be made even when inspectors are not present. The evolution and success of unattended NDA has been responsible for the capability of the IAEA to monitor large bulk-handling facilities without substantial increase in inspection effort. The integration of NDA with containment & surveillance measures and automation has been crucial to reducing inspection manpower. These systems have developed to the point where the IAEA can make credible conclusions on large high-throughput plants such as mixed-oxide (MOX) fuel fabrication or reprocessing plants.

Improving the Transparency of IAEA Safeguards Reporting  

SciTech Connect

In 2008, the Standing Advisory Group on Safeguards Implementation (SAGSI) indicated that the International Atomic Energy Agency's (IAEA) Safeguards Implementation Report (SIR) has not kept pace with the evolution of safeguards and provided the IAEA with a set of recommendations for improvement. The SIR is the primary mechanism for providing an overview of safeguards implementation in a given year and reporting on the annual safeguards findings and conclusions drawn by the Secretariat. As the IAEA transitions to State-level safeguards approaches, SIR reporting must adapt to reflect these evolutionary changes. This evolved report will better reflect the IAEA's transition to a more qualitative and information-driven approach, based upon State-as-a-whole considerations. This paper applies SAGSI's recommendations to the development of multiple models for an evolved SIR and finds that an SIR repurposed as a 'safeguards portal' could significantly enhance information delivery, clarity, and transparency. In addition, this paper finds that the 'portal concept' also appears to have value as a standardized information presentation and analysis platform for use by Country Officers, for continuity of knowledge purposes, and the IAEA Secretariat in the safeguards conclusion process. Accompanying this paper is a fully functional prototype of the 'portal' concept, built using commercial software and IAEA Annual Report data.

IAEA workshop and field trial at the Oak Ridge K-25 Site  

SciTech Connect

In March 1994, members of the International Safeguards Department in the National Security Program Office (NSPO) hosted an environmental monitoring field trial workshop for International Atomic Energy Agency (IAEA) inspectors. The workshop was held at the Oak Ridge K-25 Site and its primary purpose was to train the inspectors in the techniques needed for effective environmental sample collection and handling. The workshop emphasized both sampling theory and practice. First, detailed techniques for swipe, vegetation, soil, biota, and water-associated sampling were covered in the classroom. Subsequently, the inspectors were divided into three groups for actual sample collection in and around the K-25 locale. The collected samples were processed by the Department of Energy (DOE) Network of Analytical Laboratories using established analytical techniques. This activity is part of the IAEA ``Programme 93+2 in. assessment of measures to enhance IAEA safeguards.

Strengthening radiopharmacy practice in IAEA Member States.  

PubMed

Radiopharmaceuticals are essential components of nuclear medicine procedures. Without radiopharmaceuticals nuclear medicine procedures cannot be performed. Therefore it could be said that 'No radiopharmaceutical-no nuclear medicine.' A good radiopharmacy practice supports nuclear medicine activities by producing radiopharmaceuticals that are safe and are of the required quality in a consistent way. As with any medicinal product, radiopharmaceuticals are required to be produced under carefully controlled conditions and are tested for their quality, prior to the administration to patients, using validated standard operating procedures. These procedures are based on the principles of Good Manufacturing Practice (GMP). The GMP principles are based on scientific knowledge and applicable regulatory requirements and guidance related to radiopharmaceutical productions and use. The International Atomic Energy Agency (IAEA) is committed to promote, in the Member States (MS), a rational and practical approach for the implementation of GMP for compounding or manufacturing of diagnostic or therapeutic radiopharmaceuticals. To pursue this goal the IAEA has developed various mechanisms and collaborations with individual experts in the field and with relevant national and international institutions or organizations. IAEA's activities in promoting radiopharmaceutical science include commissioning expert advice in the form of publications on radiopharmaceutical production, quality control and usage, producing technical guidance on production and regulatory aspects related to new radiopharmaceuticals, creating guidance documentation for self or internal audits of radiopharmaceutical production facilities, producing guidance on implementation of Quality Management System and GMP in radiopharmacy, assisting in creation of specific radiopharmaceutical monographs for the International Pharmacopoeia, and developing radiopharmacy-related human resource capabilities in MS through individual and regional training courses and education programs. IAEA strongly supports development of clinical nuclear medicine services by assisting MS in setting up reliable Radiopharmaceutical production facilities for single photon emission computed tomography, positron emission tomography, and for therapeutic applications.

RECRUITMENT OF U.S. CITIZENS FOR VACANCIES IN IAEA SAFEGUARDS.  

SciTech Connect

The International Atomic Energy Agency (IAEA) relies on its member states to assist with recruiting qualified individuals for positions within the IAEA's secretariat. It is likewise important to the U.S. government for U.S. citizens to take positions with the IAEA to contribute to its success. It is important for persons within and outside the U.S. nuclear and safeguards industries to become aware of the job opportunities available at the IAEA and to be informed of important vacancies as they arise. The International Safeguards Project Office (ISPO) at Brookhaven National Laboratory (BNL) is tasked by the U.S. government with recruiting candidates for positions within the Department of Safeguards at the IAEA and since 1998, has been actively seeking methods for improving outreach. In addition, ISPO has been working more closely with the IAEA Division of Personnel. ISPO staff members attend trade shows to distribute information about IAEA opportunities. The shows target the nuclear industry as well as shows that are unrelated to the nuclear industry. ISPO developed a web site that provides information for prospective candidates. They have worked with the IAEA to understand its recruitment processes, to make suggestions for improvements, and to understand employment benefits so they can be communicated to potential U.S. applicants. ISPO is also collaborating with a State Department working group that is focused on increasing U.S. representation within the United Nations as a whole. Most recently Secretary of State Condoleezza Rice issued a letter to all Federal Agency heads encouraging details and transfers of their employees to international organizations to the maximum extent feasible and with due regard to their manpower requirements. She urged all federal agencies to review their detail and transfer policies and practices to ensure that employment in international organizations is promoted in a positive and active manner. In addition, she wrote that it is important that agencies examine their policies and practices for returning employees from details and transfer to ensure that reintegration procedures result in both the agency and such employees receiving optimal benefit from the international organization experience. This paper follows a 1999 paper on the same topic.

Analysis of historical delta values for IAEA/LANL NDA training courses  

SciTech Connect

The Los Alamos National Laboratory (LANL) supports the International Atomic Energy Agency (IAEA) by providing training for IAEA inspectors in neutron and gamma-ray Nondestructive Assay (NDA) of nuclear material. Since 1980, all new IAEA inspectors attend this two week course at LANL gaining hands-on experience in the application of NDA techniques, procedures and analysis to measure plutonium and uranium nuclear material standards with well known pedigrees. As part of the course the inspectors conduct an inventory verification exercise. This exercise provides inspectors the opportunity to test their abilities in performing verification measurements using the various NDA techniques. For an inspector, the verification of an item is nominally based on whether the measured assay value agrees with the declared value to within three times the historical delta value. The historical delta value represents the average difference between measured and declared values from previous measurements taken on similar material with the same measurement technology. If the measurement falls outside a limit of three times the historical delta value, the declaration is not verified. This paper uses measurement data from five years of IAEA courses to calculate a historical delta for five non-destructive assay methods: Gamma-ray Enrichment, Gamma-ray Plutonium Isotopics, Passive Neutron Coincidence Counting, Active Neutron Coincidence Counting and the Neutron Coincidence Collar. These historical deltas provide information as to the precision and accuracy of these measurement techniques under realistic conditions.

Reference Material for Radionuclides in Sediment, IAEA-384 (Fangataufa Lagoon Sediment)  

SciTech Connect

The IAEA Marine Environment Laboratory (IAEA-MEL) in Monaco has conducted intercomparison exercises on radionuclides in marine samples for many years as part of its contribution to the IAEA's program of Analytical Quality Control Services (AQCS). An important part of the AQCS program has been a production of Reference Materials (RMs) and their provision to radioanalytical laboratories. The RMs have been developed for different marine matrices (sediment, water, biota), with accuracy and precision required for the present state of the art of radiometrics and mass spectrometry methods. The RMs have been produced as the final products of world-wide intercomparison exercises organized during last 30 years. A total of 44 intercomparison exercises were undertaken and 39 RMs were produced for radionuclides in the marine environment. All required matrices (seawater, biota, sediment) have been covered with radionuclide concentrations ranging from typical environmental levels to elevated levels affected by discharges from nuclear reprocessing plants. The long-term availability of RMs (over 10 years) requires the use of very specific techniques to collect and pretreat large quantities of material (e.g., in excess of 100 kg) in order to ensure sample stability and homogenization of any analytes of interest. The production of a RM is therefore a long process, covering the identification of needs, sample collection, pre-treatment, homogenization, bottling, distribution to laboratories, evaluation of data, preliminary reporting, additional analyses in expert laboratories, certification of the material, and finally issuing the RM. In this paper we describe a reference material IAEA-384, Fangataufa lagoon sediment, designed for determination of anthropogenic and natural radionuclides in the marine environment. This RM has been prepared with the aim of testing the performance of analytical laboratories to measure the activity of these radionuclides in a sediment sample contaminated by elevated levels of fallout from nuclear weapons tests. Participating laboratories were requested to determine as many radionuclides as possible by radiometric (alpha, beta and gamma-spectrometry) as well as by mass spectrometry methods (e.g., ICPMS - Inductively Coupled Plasma Mass Spectrometry, TIMS - Thermal Ionization Mass Spectrometry, AMS - Accelerator Mass Spectrometry).

Analytical quality of environmental analysis: Recent results and future trends of the IAEA-ILMR's Analytical Quality Control Program  

SciTech Connect

The Analytical Quality Control Services Program of the IAEA-ILMR covers a wide variety of intercalibration and reference materials. The purpose of the program is to ensure the comparability of the results obtained by the different participants and to enable laboratories engaged in low-level analyses of marine environmental materials to control their analytical performance. Within the past five years, the International Laboratory of Marine Radioactivity in Monaco has organized eight intercomparison exercises, on a world-wide basis, on natural materials of marine origin comprising sea water, sediment, seaweed and fish flesh. Results on artificial (fission and activation products, transuranium elements) and natural radionuclides were compiled and evaluated. Reference concentration values were established for a number of the intercalibration samples allowing them to become certified as reference materials available for general distribution. The results of the fish flesh sample and those of the deep-sea sediment are reviewed. The present status of three on-going intercomparison exercises on post-Chernobyl samples IAEA-306 (Baltic Sea sediment), IAEA-307 (Mediterranean sea-plant Posidonia oceanica) and IAEA-308 (Mediterranean mixed seaweed) is also described. 1 refs., 4 tabs.

Nonproliferation, Disarmament, and the IAEA in Tomorrow's World  

ScienceCinema

International Atomic Energy Agency (IAEA) safeguards have evolved considerably during the last five decades and have become an integral part of the international non-proliferation regime and the global security system. To carry on serving well the international community, they need to continue to move with the times -- especially in light of the renewed interest in nuclear energy and its projected expansion in the coming years, which could bring additional nuclear facilities, material and activities under IAEA safeguards. The projected nuclear ˜renaissance" may pose increased proliferation risks as nuclear material, technology and know-how spread in an increasingly globalized world. The presentation will provide an overview of the IAEA safeguards system and describe current verification challenges and potential new IAEA roles.

Assessment of Alternative Funding Mechanisms for the IAEA  

SciTech Connect

While the International Atomic Energy Agency (IAEA) has enjoyed substantial success and prestige in the international community, there is growing concern that global demographic trends, advances in technology and the trend towards austerity in Member State budgets will stretch the Agency’s resources to a point where it may no longer be possible to execute its multifaceted mission in its entirety. As part of an ongoing effort by the Next Generation Safeguards Initiative to evaluate the IAEA’s long-term budgetary concerns , this paper proposes a series of alternate funding mechanisms that have the potential to sustain the IAEA in the long-term, including endowment, charity, and fee-for-service funding models.

The radionuclide laboratory at the Austrian Research Centers Seibersdorf (ATL03) was installed to support the international monitoring system for verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT and Text of the establishment of a Preparatory Commission for the Comprehensive Test-Ban-Treaty Organization, 1996). Therefore, the background of a high-purity germanium detection system has been reduced by developing a high sophisticated active and passive detector shielding. The entire system is encapsulated in an iron-castle and placed into a fall-out shelter. The final count rate, achieved over the energy interval from 40 to 2700 keV, amounts to 0.18 counts s(-1) kg(-1) (Ge). PMID:11839044

USSP-IAEA WORKSHOP ON ADVANCED SENSORS FOR SAFEGUARDS.  

SciTech Connect

The IAEA Medium Term Strategy (2006-2011) defines a number of specific goals in respect to the IAEA's ability to provide assurances to the international community regarding the peaceful use of nuclear energy through States adherences to their respective non-proliferation treaty commitments. The IAEA has long used and still needs the best possible sensors to detect and measure nuclear material. The Department of Safeguards, recognizing the importance of safeguards-oriented R&D, especially targeting improved detection capabilities for undeclared facilities, materials and activities, initiated a number of activities in early 2005. The initiatives included letters to Member State Support Programs (MSSPs), personal contacts with known technology holders, topical meetings, consultant reviews of safeguards technology, and special workshops to identify new and novel technologies and methodologies. In support of this objective, the United States Support Program to IAEA Safeguards hosted a workshop on ''Advanced Sensors for Safeguards'' in Santa Fe, New Mexico, from April 23-27, 2007. The Organizational Analysis Corporation, a U.S.-based management consulting firm, organized and facilitated the workshop. The workshop's goal was to help the IAEA identify and plan for new sensors for safeguards implementation. The workshop, which was attended by representatives of seven member states and international organizations, included presentations by technology holders and developers on new technologies thought to have relevance to international safeguards, but not yet in use by the IAEA. The presentations were followed by facilitated breakout sessions where the participants considered two scenarios typical of what IAEA inspectors might face in the field. One scenario focused on an enrichment plant; the other scenario focused on a research reactor. The participants brainstormed using the technologies presented by the participants and other technologies known to them to propose techniques and methods that could be used by the IAEA to strengthen safeguards. Creative thinking was encouraged during discussion of the proposals. On the final day of the workshop, the OAC facilitators summarized the participant's ideas in a combined briefing. This paper will report on the results of the April 2007 USSP-IAEA Workshop on Advanced Sensors for Safeguards and give an overview of the proposed technologies of greatest promise.

Strengthening IAEA Safeguards: Challenges Ahead (437th Brookhaven Lecture)  

ScienceCinema

The International Atomic Energy Agency (IAEA), headquartered in Vienna, Austria, was established in 1957 to promote the peaceful uses of nuclear energy and to discourage its military use. The agency's success in halting nuclear proliferation and in enhancing nuclear safeguards and security have been recognized internationally, including with the 2005 Nobel Peace Prize awarded to the IAEA and its Director General. BNL has long had a role in the IAEA, by providing technical advice and assistance to its safeguards department. In fact, the IAEA's International Safeguards Project Office (ISPO) is headquartered at the Lab and is responsible for the management of U.S. programs supporting ISPO. In the 437th Brookhaven Lecture on Wednesday, June 25th, at 4 p.m. in Berkner Hall, physicist Michael Rosenthal of the Energy, Environment & National Security Directorate will discuss the challenges facing the IAEA and ISPO in light of the world political situation and today's tight budgets, and BNL's role in finding and implementing solutions.

Reducing the risks from radon indoors: an IAEA perspective.  

PubMed

The IAEA has a mandate to develop, in collaboration with other relevant international organisations, 'standards of safety for protection of health and minimisation of danger to life and property', and to provide for the application of these standards. The most recent edition of the International Basic Safety Standards includes, for the first time, requirements to protect the public from exposure due to radon indoors. As a result, the IAEA has already developed guidance material in line with accepted best international practice and an international programme to assist its Member States in identifying and addressing high radon concentrations in buildings is being prepared. This paper overviews the current situation around the world and summarises the management approach advocated by the IAEA. A number of important scientific and policy issues are identified and discussed from the point-of-view of how they may impact on national action plans and strategies. Finally, the assistance and support available through the Agency is described. PMID:24743761

Implementation of the IAEA Additional Protocol in the Philippines: USDOE/PNRI Cooperation  

SciTech Connect

The Philippines entered into force the International Atomic Energy Agency (IAEA) Additional Protocol (AP) in February 2010. The Philippine Nuclear Research Institute (PNRI) is the government agency responsible for implementing the AP. In June 2010 the IAEA invited the U.S. Department of Energy (DOE) to help conduct a joint national training seminar on the AP. DOE presented to PNRI its AP international technical assistance program, administered by the International Nuclear Safeguards and Engagement Program (INSEP), which helps partner countries implement the AP. In coordination with the IAEA, DOE established this program in 2008 to complement IAEA AP seminars with long-term country-specific cooperation from the perspective of a Member State. The US version of the AP is the same version as that of non-nuclear weapon states except for the addition of a national security exclusion. Due to this, DOE cooperation with other countries enables the sharing of valuable lessons learned in implementing the AP. DOE/INSEP described to PNRI the various areas of cooperation it offers to interested countries, whether they are preparing for entry into force or already implementing the AP. Even countries that have entered the AP into force are sometimes not fully prepared to implement it well, and welcome cooperation to improve their implementation process. PNRI and DOE/INSEP subsequently agreed to cooperate in several areas to enhance the efficiency and effectiveness of the Philippines AP implementation. These areas include providing working-level training to PNRI staff and preparing an information document that details that training for future reference, assisting with the development of an outreach program and procedures for AP reporting and complementary access, and identifying Annex II equipment and non-nuclear materials whose export must be reported under the AP. DOE laboratory representatives, funded by INSEP, met again with PNRI in February 2011 to provide training for PNRI AP staff and investigate specific ways to improve implementation. Another meeting in July 2011 focused on preparations for outreach to industry and universities. In this paper PNRI describes current implementation of the AP in the Philippines, and both DOE/INSEP and PNRI provide their perspectives on their cooperation to enhance that implementation.

Technical implementation in support of the IAEA`s remote monitoring field trial at the Oak Ridge Y-12 Plant  

SciTech Connect

A remote monitoring system (RMS) field trial will be conducted for the International Atomic Energy Agency (IAEA) on highly enriched uranium materials in a vault at the Oak Ridge Y-12 Plant. Remote monitoring technologies are being evaluated to verify their capability to enhance the effectiveness and timeliness of IAEA safeguards in storage facilities while reducing the costs of inspections and burdens on the operator. Phase one of the field trial, which involved proving the satellite transmission of sensor data and safeguards images from a video camera activated by seals and motion sensors installed in the vault, was completed in September 1995. Phase two involves formal testing of the RMS as a tool for use by the IAEA during their tasks of monitoring the storage of nuclear material. The field trial to be completed during early 1997 includes access and item monitoring of nuclear materials in two storage trays. The RMS includes a variety of Sandia, Oak Ridge, and Aquila sensor technologies that provide video monitoring, radiation attribute measurements, and container identification to the on-site data acquisition system (DAS) by way of radio-frequency and Echelon LONWorks networks. The accumulated safeguards information will be transmitted to the IAEA via satellite (COMSAT/RSI) and international telephone lines.

The International Atomic Energy Agency (IAEA) relies on its member states to assist with recruiting qualified individuals for positions within the IAEA's secretariat. It is important that persons within and outside the US nuclear and safeguards industries become aware of career opportunities available at the IAEA, and informed about important vacancies. The IAEA has established an impressive web page to advertise opportunities for employment. However, additional effort is necessary to ensure that there is sufficient awareness in the US of these opportunities, and assistance for persons interested in taking positions at the IAEA. In 1998, the Subgroup on Safeguards Technical Support (SSTS) approved a special task under the US Support Program to IAEA Safeguards (USSP) for improving US efforts to identify qualified candidates for vacancies in IAEA's Department of Safeguards. The International Safeguards Project Office (ISPO) developed a plan that includes increased advertising, development of a web page to support US recruitment efforts, feedback from the US Mission in Vienna, and interaction with other recruitment services provided by US professional organizations. The main purpose of this effort is to educate US citizens about opportunities at the IAEA so that qualified candidates can be identified for the IAEA's consideration.

The International Atomic Energy Agency (IAEA) under its mandate of developing and applying standards of radiation safety has initiated a number of activities in recent years on radiation protection in interventional cardiology. These activities are implemented through four mechanisms, namely training, providing information through the website, research projects and assistance to Member States through Technical Cooperation (TC) projects. Major international initiatives have been taken in the area of training where more than half a dozen regional training courses have been conducted for cardiologists from over 50 countries. Additionally four national training events for over 300 medical and paramedical staff members involved in interventional procedures were held. The training material is freely available on CD from the IAEA. The newly established website provides information on radiation protection issues [1]. Two coordinated research projects have just been completed where peak skin doses to patients undergoing high dose interventional procedures were studied and factors to manage patient doses were identified. The technical cooperation projects involving protection in cardiac interventional procedures have 30 countries as participants.

Monte Carlo simulation of correction factors for IAEA TLD holders.  

PubMed

The IAEA standard thermoluminescent dosimeter (TLD) holder has been developed for the IAEA/WHO TLD postal dose program for audits of high-energy photon beams, and it is also employed by the ESTRO-QUALity assurance network (EQUAL) and several national TLD audit networks. Factors correcting for the influence of the holder on the TL signal under reference conditions have been calculated in the present work from Monte Carlo simulations with the PENELOPE code for (60)Co gamma-rays and 4, 6, 10, 15, 18 and 25 MV photon beams. The simulation results are around 0.2% smaller than measured factors reported in the literature, but well within the combined standard uncertainties. The present study supports the use of the experimentally obtained holder correction factors in the determination of the absorbed dose to water from the TL readings; the factors calculated by means of Monte Carlo simulations may be adopted for the cases where there are no measured data.

Micro-beam X-ray fluorescence and absorption imaging techniques at the IAEA Laboratories  

NASA Astrophysics Data System (ADS)

X-ray tube based, micro-beam X-ray fluorescence scanning spectrometer has been equipped with two energy dispersive X-ray detectors. The two-detector configuration allows for simultaneous collection of X-ray fluorescence (XRF) and transmitted X-ray beam signals with a spatial resolution in the range of 10-50 ?m, depending on the X-ray focussing element in use. The XRF signal is collected with a standard, liquid nitrogen cooled Si(Li) detector. The X-ray beam transmitted through the sample is acquired with a thermoelectrically cooled, silicon drift (SD) detector. The data acquisition is carried out in a fully automatic way under control of the SPECTOR-LOCATOR software. The software controls the scanning procedure and X-ray spectra acquisition during the scan. The energy dispersive X-ray spectra collected at every "pixel" are stored for off-line processing. For selected regions of interest (ROI's), the element maps are constructed and displayed on-line. The spectrometer has been used for mapping elemental distributions and for performing 2D- and 3D-tomograpic imaging of minute objects in X-ray absorption and in X-ray fluorescence mode. A unique feature of the described system is simultaneous utilization of the two detectors, Si(Li) and SD, which adds new options for quantitative analysis and data interpretation. Examples of elemental mapping and 3D tomographic imaging as well as the advanced features of the SPECTOR-LOCATOR measurement control and data acquisition software are presented in this work.

End user needs for enhanced IAEA Safeguards Information Management Capabilities  

SciTech Connect

The International Atomic Energy Agency is undertaking a program for strengthening its safeguards on the recognition that safeguards must give assurance not only of the non-diversion of declared material or that declared facilities are not being misused, but also of the absence of any undeclared nuclear activities in States which have signed comprehensive safeguards agreements with the Agency. The IAEA has determined that the detection of undeclared nuclear activities and the creation of confidence in the continuing peaceful use of declared material and facilities is largely dependent on more information being made available to the Agency and on the capability of the Agency to make more effective use of this additional information, as well as existing information.

Patient exposure tracking: the IAEA smart card project.  

PubMed

The existing approach of radiation protection is largely based on the collective dose to the population with provisions for protection at an individual level through justification and optimisation. With the individual patient dose now exceeding the life-long occupational dose to a worker in a typical radiology practice, there is a need to establish approaches based on the protection of an individual patient. Radiation exposure tracking seems a way forward in this respect. Technological advances in recent years have provided opportunities for tracking to becoming a reality. The IAEA project on Smart Card/SmartRadTrack is described in this paper. The tracking is now a reality in a few dozen centres in many countries connected by picture archiving and communication systems, and there is hope that this will extend to cover other countries and continents.

IAEA coordinated research activities on materials for advanced reactor systems  

NASA Astrophysics Data System (ADS)

After the recent accident at the Fukushima Daiichi Nuclear Power Plant, public resentment towards nuclear energy is very high; however it is also important to emphasise that for other facilities the safety record has been remarkably good when compared to those of other new or conventional energy technologies. In addition to clear safety improvements new systems will have increased thermal efficiency, maximised fuel use, and reduced nuclear waste production. In order to initiate commercial deployment of power reactors, small scale demonstrations of such new systems are urgently needed. This will help to develop, test and qualify new structural materials with improved properties with respect to radiation, corrosion, thermal and other degradation processes. To solve all challenges related to the performance parameters of such materials, internationally driven efforts must focus on research, targeted testing, and final selection of appropriate materials. This is recognised as a key milestone in successful demonstration and future deployment of newly designed nuclear reactors. Because of clear synergies between fusion and fission research and development communities have been identified, closer cooperation of research groups has been stimulated. Although some operational conditions are expected to change, many basic features will remain similar. In addition to the material science effort, new experimental facilities are being developed for the study of high-radiation damage effects on the microstructure of candidate materials prior to their qualification. During last 5 years, the International Atomic Energy Agency (IAEA) launched several coordinated research activities in this specific, but very important field. This paper gives a summary of on-going IAEA activities related to the development and characterisation of structural and plasma facing materials for nuclear energy.

Four Years of Practical Arrangements between IAEA and Moscow SIA 'Radon': Preliminary Results - 13061  

SciTech Connect

The International Education Training Centre (IETC) at Moscow State Unitary Enterprise Scientific and Industrial Association 'Radon' (SIA 'Radon'), in co-operation with the International Atomic Energy Agency (IAEA), has developed expertise and provided training to waste management personnel for the last 15 years. Since 1997, the educational system of the enterprise with the support of the IAEA has acquired an international character: more than 470 experts from 35 countries- IAEA Member States completed the professional development. Training is conducted at various thematic courses or fellowships for individual programs and seminars on IAEA technical projects. In June 2008 a direct agreement (Practical Arrangements) was signed between SIA 'Radon' and the IAEA on cooperation in the field of development of new technologies, expert's advice to IAEA Member States, and, in particular, the training of personnel in the field of radioactive waste management (RWM), which opens up new perspectives for fruitful cooperation of industry professionals. The paper summarizes the current experience of the SIA 'Radon' in the organization and implementation of the IAEA sponsored training and others events and outlines some of strategic educational elements, which IETC will continue to pursue in the coming years.

The IAEA handbook on radionuclide transfer to wildlife.  

PubMed

An IAEA handbook presenting transfer parameter values for wildlife has recently been produced. Concentration ratios (CRwo-media) between the whole organism (fresh weight) and either soil (dry weight) or water were collated for a range of wildlife groups (classified taxonomically and by feeding strategy) in terrestrial, freshwater, marine and brackish generic ecosystems. The data have been compiled in an on line database, which will continue to be updated in the future providing the basis for subsequent revision of the Wildlife TRS values. An overview of the compilation and analysis, and discussion of the extent and limitations of the data is presented. Example comparisons of the CRwo-media values are given for polonium across all wildlife groups and ecosystems and for molluscs for all radionuclides. The CRwo-media values have also been compared with those currently used in the ERICA Tool which represented the most complete published database for wildlife transfer values prior to this work. The use of CRwo-media values is a pragmatic approach to predicting radionuclide activity concentrations in wildlife and is similar to that used for screening assessments for the human food chain. The CRwo-media values are most suitable for a screening application where there are several conservative assumptions built into the models which will, to varying extents, compensate for the variable data quality and quantity, and associated uncertainty.

Radiation processing of natural polymers: The IAEA contribution  

NASA Astrophysics Data System (ADS)

Radiation processing offers a clean and additive-free method for preparation of value-added novel materials based on renewable, non-toxic, and biodegradable natural polymers. Crosslinked natural polymers can be used as hydrogel wound dressings, face cleaning cosmetic masks, adsorbents of toxins, and non-bedsore mats; while low molecular weight products show antibiotic, antioxidant, and plant-growth promoting properties. Recognizing the potential benefits that radiation technology can offer for processing of natural polymers into useful products, the IAEA implemented a coordinated research project (CRP) on "Development of Radiation-processed products of Natural Polymers for application in Agriculture, Healthcare, Industry and Environment". This CRP was launched at the end of 2007 with participation of 16 MS to help connecting radiation technology and end-users to derive enhanced benefits from these new value-added products of radiation-processed natural materials. In this paper the results of activities in participating MS related to this work will be presented.

New Organic Stable Isotope Reference Materials for Distribution through the USGS and the IAEA  

NASA Astrophysics Data System (ADS)

The widespread adoption of relative stable isotope-ratio measurements in organic matter by diverse scientific disciplines is at odds with the dearth of international organic stable isotopic reference materials (RMs). Only two of the few carbon (C) and nitrogen (N) organic RMs, namely L-glutamic acids USGS40 and USGS41 [1], both available from the U.S. Geological Survey (USGS) and the International Atomic Energy Agency (IAEA), provide an isotopically contrasting pair of organic RMs to enable essential 2-point calibrations for ?-scale normalization [2, 3]. The supply of hydrogen (H) organic RMs is even more limited. Numerous stable isotope laboratories have resorted to questionable practices, for example by using 'CO2, N2, and H2 reference gas pulses' for isotopic calibrations, which violates the principle of identical treatment of sample and standard (i.e., organic unknowns should be calibrated directly against chemically similar organic RMs) [4], or by using only 1 anchor instead of 2 for scale calibration. The absence of international organic RMs frequently serves as an excuse for indefensible calibrations. In 2011, the U.S. National Science Foundation (NSF) funded an initiative of 10 laboratories from 7 countries to jointly develop much needed new organic RMs for future distribution by the USGS and the IAEA. The selection of targeted RMs attempts to cover various common compound classes of broad technical and scientific interest. We had to accept compromises to approach the ideal of high chemical stability, lack of toxicity, and low price of raw materials. Hazardous gases and flammable liquids were avoided in order to facilitate international shipping of future RMs. With the exception of polyethylene and vacuum pump oil, all organic RMs are individual, chemically-pure substances, which can be used for compound-specific isotopic measurements in conjunction with liquid and gas chromatographic interfaces. The compounds listed below are under isotopic calibration by the 10 laboratories. Successfully calibrated organic RMs could become available as early as 2015. - n-Hexadecane (C16 n-alkane), three H, C-isotopic varieties; - Glycine (amino acid), three H, C, N-isotopic varieties; - L-valine (amino acid), three H, C, N-isotopic varieties; - Methyl n-heptadecanoate (methyl ester of C17 n-alkanoic fatty acid); - Methyl icosanoate (methyl ester of C20 n-alkanoic fatty acid), three H, C-isotopic varieties; - Caffeine, three H, C, N-isotopic varieties; - Hydrocarbon vacuum pump oils, two H-isotopic varieties; - Polyethylene powder, and possibly a 2H and 13C-enriched polyethylene string.

Lessons from UNSCOM/IAEA applicable to nuclear arms control  

SciTech Connect

In early 1991, the Security Council of the United Nations tasked the Director General of the International Atomic Energy Agency, with the assistance and cooperation of the United Nations Special Commission, to oversee the destruction, removal or rendering harmless of nuclear weapons material and capabilities in Iraq. The conduct of the nuclear inspections, and the subsequent activities (identification, destruction, removal rendering harmless), have provided a wealth of experience and insight into the inspection and monitoring process as well as into the political realities of such an operation. The early inspections were conducted in an atmosphere of discovery and inexperience on both the part of the Iraqis and the IAEA and UNSCOM. As time went on, the Iraqis became more adept at hiding and obscuring relevant documents and equipment, and the inspection teams became more knowledgeable about inspection and investigative techniques, and the pre-existing Iraqi programs. A continuous monitoring presence in Iraq has now been established and an import/export monitoring regime is being developed. While steps taken to date have proven effective in inhibiting resumption of nuclear weaponization activities, it remains to be seen how effective these measures will be in the future. The external and internal conditions which led the Iraqi leadership to undertake a nuclear weaponization program have not changed, and the prognosis for the long term is uncertain. The entire process in Iraq has shown how fragile are the tools available to the international community, and how a determined proliferator can evade inspection and monitoring measures. Such measures cannot prevent nuclear proliferation, they can only hope to deter it, or, failing in that, detect it.

Containment and surveillance -- A principal IAEA safeguards measure  

SciTech Connect

The growth of the safeguards inspectorate of the Agency, spanning more than 40 years, has produced a variety of interesting subjects (legal, technical, political, etc.) for recollection, discussion, and study. Although the Agency was established in 1957, the first practical inspections did not occur until the early 1960s. In the early inspections, thee was little C/S equipment available, and no optical surveillance was used. However, by the third decade of the IAEA, the 1980s, many technology advances were made, and the level of C/S equipment activities increased. By the late 1980s, some 200 Twin Minolta film camera systems were deployed by the Agency for safeguards use. At the present time, the Agency is evaluating and beginning to implement remote monitoring as part of the Strengthened Safeguards System. However, adoption of remote monitoring by international agencies cannot occur rapidly because of the many technical and policy issues associated with this activity. A glimpse into the future indicates that an important element of safeguards instrumentation will be the merging of C/S and NDA equipment into integrated systems. The use of modern interior area monitors in International Safeguards also offers a great potential for advancing C/S measures. The research in microsensors is in its infancy, and the opportunities for their reducing the cost, increasing the life time, and increasing the reliability of sensors for safeguards applications are manifold. A period may be approaching in which the terminology of C/S will no longer have its original meaning, as integrated systems combining NDA instruments and C/S instruments are already in use and are expected to be the norm in the near future.

IAEA SAFEGUARDS DURING PLUTONIUM STABILIZATION AT HANFORDS PLUTONIUM FINISHING PLANT (PFP)  

SciTech Connect

The Vault at the Plutonium Finishing Plan (PFP) became subject to the International Atomic Energy Agency (IAEA) safeguards beginning in 1994 as part of the US excess fissile material program. The inventory needed to be stabilized and repackaged for long-term storage to comply with Defense Nuclear Facilities Safety Board Recommendation 94-1. In 1998, the United States began negotiations with IAEA to develop methods to maintain safeguards as this material was stabilized and repackaged. The Design Information Questionnaire was revised and submitted to the IAEA in 2002 describing how PFP would be modified to accommodate the stabilization process line. The operation plan for 2003 was submitted describing the proposed schedules for removing materials for stabilization. Stabilization and repackaging activities for the safeguarded plutonium began in January 2003 and were completed in December 2003. The safeguards approach implemented at the Hanford Site was a combination of the original baseline approach augmented by a series of five vault additions of stabilized materials followed by five removals of unstabilized materials. IAEA containment and surveillance measures were maintained until the unstabilized material was removed. Following placement of repackaged material (most from the original safeguarded stock) into the storage vault, the IAEA conducted inventory change verification measurements and then established containment and surveillance. As part of the stabilization campaign, the IAEA developed new measurement methods and calibration standards representative of the materials and packaging. The annual physical inventory verification was conducted on the normal IAEA schedule following the fourth additional/removal phase. Plant activities and the impacts on operations are described.

Cooperation between SSACs/RSACs and the IAEA Under the State-Level Concept:  

SciTech Connect

The role of State and Regional Systems of Accounting for and Control of Nuclear Materials (SSACs/RSACs) will increase within the framework of the state-level concept that is being implemented by the International Atomic Energy Agency (IAEA). In order to effectively implement the concept and further establish a state-level approach, which is sought to tailor safeguards activities in a specific state accordingly, collaboration between SSACs/RSACs and the IAEA is very important. Nevertheless, the implementation of such concept is not simple. Optimal relationship between operators and national/governmental authorities and between SSACs/RSACs and the IAEA is an evolving process. Benefits of such an approach as well as roles and responsibilities must be made clear to all parties involved. Acknowledging the uniqueness and diversity of SSACs/RSACs is a first step, followed by the implementation of confidence-building measures that result from an efficient communication process, and culminating with a transparent technical cooperation program. This paper analyses various aspects of the complex relationship among all parties involved in the implementation of the state-level concept: operators, national authorities, government agencies, SSACs/RSACs, and the IAEA. The author analyses the intricate network of possibilities to improve cooperation and discusses issues involving the provision of additional and voluntary information by SSACs/RSACs to the IAEA.

IAEA Safeguards and technical support programs: POTAS in the 1990s  

SciTech Connect

The US Program of Technical Assistance to IAEA Safeguards (POTAS) has since 1978 provided technology and technical assistance to the IAEA to support its nuclear safeguards activities. The present level of support, $6.9 million per year, equals 10% of the Department of Safeguards annual budget. During the next decade, the International Atomic Energy Agency (IAEA) will face new technical challenges in carrying out its verification activities. To help the IAEA acquire the technology and other technical support that it will require in the 1990s, POTAS expects to continue its assistance, both in the areas established in the past and in additional areas dictated by newly identified IAEA safeguards requirements. This paper will look at the political and policy context within which the Department of Safeguards, and hence POTAS, operates, and how that context is expected to evolve over the next decade. The roles and functions of POTAS will be identified and discussed in terms of their historical evolution. Lastly, the paper will consider how POTAS is expected to change during the 1990s, both to maintain effectiveness in existing roles and functions, and to meet the challenge of the changing policy context. 5 refs.

For safety reasons, the U.S. Department of Energy (DOE) is preparing to stabilize and package plutonium oxide currently subject to International Atomic Energy Agency safeguards at the Rocky Flats Environmental Technology Site (RFETS) beginning in the year 2001. The Hanford Site will also stabilize and package plutonium materials under IAEA safeguards. The U.S. and the IAEA began consultations in late 1996 to develop an approach to the application of safeguards during stabilization and packaging. With the plans to ship RFETS plutonium to Savannah River for interim storage prior to final disposition, this work has been extended to include safeguards during shipment. This paper will discuss the elements of a joint U.S./IAEA proposal for this task.

Approach to IAEA material-balance verification at the Portsmouth Gas Centrifuge Enrichment Plant  

SciTech Connect

This paper describes a potential approach by which the International Atomic Energy Agency (IAEA) might verify the nuclear-material balance at the Portsmouth Gas Centrifuge Enrichment Plant (GCEP). The strategy makes use of the attributes and variables measurement verification approach, whereby the IAEA would perform independent measurements on a randomly selected subset of the items comprising the U-235 flows and inventories at the plant. In addition, the MUF-D statistic is used as the test statistic for the detection of diversion. The paper includes descriptions of the potential verification activities, as well as calculations of: (1) attributes and variables sample sizes for the various strata, (2) standard deviations of the relevant test statistics, and (3) the detection sensitivity which the IAEA might achieve by this verification strategy at GCEP.

Field measurements to support IAEA procedures development for fuel assembly and fuel rod active length verification  

SciTech Connect

The activities performed in verification of reactor fuel rods and assemblies by International Atomic Energy Agency (IAEA) safeguards inspectors include measurements of the length of the enriched uranium sections in fuel assemblies and fuel rods. These measurements are normally made with the IAEA hand-held gamma monitor (HM-4) on fuel elements containing only enriched uranium. Many fuel rods currently in use contain natural uranium end sections and several different [sup 235]U enrichment zones. To support development of standard procedures for IAEA nondestructive assay (NDA) measurements, a field measurement campaign was carried out to evaluate the FM-4 measurements and to investigate the feasibility of extending the HM-4 measurements to fuel rods and assemblies containing both natural and enriched uranium sections. The results show that the enriched fuel length can be measured to within [plus minus] 1 to 2 cm in the presence of natural uranium sections and to within [plus minus] 0.5 = when only enriched uranium is present. Based on the results from these measurements, a standard procedure, Measurement of Active Fuel Length in Fuel Assemblies and Fuel Rods Using the HM-4,'' has been drafted for review by the IAEA.

The US Support Program to IAEA Safeguards Priority of Training and Human Resources  

SciTech Connect

The U.S. Support Program to IAEA Safeguards (USSP) priority of training and human resources is aimed at providing the Department of Safeguards with an appropriate mixture of regular staff and extrabudgetary experts who are qualified to meet the IAEA's technical needs and to provide personnel with appropriate instruction to improve the technical basis and specific skills needed to perform their job functions. The equipment and methods used in inspection activities are unique, complex, and evolving. New and experienced safeguards inspectors need timely and effective training to perform required tasks and to learn new skills prescribed by new safeguards policies or agreements. The role of the inspector has changed from that of strictly an accountant to include that of a detective. New safeguards procedures are being instituted, and therefore, experienced inspectors must be educated on these new procedures. The USSP also recognizes the need for training safeguards support staff, particularly those who maintain and service safeguards equipment (SGTS), and those who perform information collection and analysis (SGIM). The USSP is committed to supporting the IAEA with training to ensure the effectiveness of all staff members and will continue to offer its assistance in the development and delivery of basic, refresher, and advanced training courses. This paper will discuss the USSP ongoing support in the area of training and IAEA staffing.

Approach to IAEA material-balance verification with intermittent inspection at the Portsmouth Gas Centrifuge Enrichment Plant  

SciTech Connect

This paper describes a potential approach by which the International Atomic Energy Agency (IAEA) might verify the nuclear-material balance at the Portsmouth Gas Centrifuge Enrichment Plant (GCEP) for the circumstance in which the IAEA inspections occur on an intermittent basis. The verification approach is a variation of the standard IAEA attributes/variables measurement-verification method. This alternative approach is useful and applicable at the Portsmouth GCEP, which will ship all its product and tails UF/sub 6/ to United States facilities not eligible for IAEA safeguards. The paper reviews some of the relevant results of the Hexapartite Safeguards Project (HSP), describes the standard IAEA material-balance-verification approach for bulk-handling facilities, and provides the procedures to be followed in handling and processing UF/sub 6/ cylinders at the Portsmouth GCEP. The paper then discusses the assumptions made in the approach, and derives a formula for the probability with which the IAEA could detect the diversion of a significant quantity of uranium (75 kg of U-235 in depleted, normal, and low-enriched uranium) if this method were applied. The paper also provides numerical examples of IAEA detection probability should the operator divert uranium from the feed, product, or tails streams for the Portsmouth GCEP with a capacity of 1100 tonnes of separative work per year.

NOTE: Monte Carlo simulation of correction factors for IAEA TLD holders  

NASA Astrophysics Data System (ADS)

The IAEA standard thermoluminescent dosimeter (TLD) holder has been developed for the IAEA/WHO TLD postal dose program for audits of high-energy photon beams, and it is also employed by the ESTRO-QUALity assurance network (EQUAL) and several national TLD audit networks. Factors correcting for the influence of the holder on the TL signal under reference conditions have been calculated in the present work from Monte Carlo simulations with the PENELOPE code for 60Co ?-rays and 4, 6, 10, 15, 18 and 25 MV photon beams. The simulation results are around 0.2% smaller than measured factors reported in the literature, but well within the combined standard uncertainties. The present study supports the use of the experimentally obtained holder correction factors in the determination of the absorbed dose to water from the TL readings; the factors calculated by means of Monte Carlo simulations may be adopted for the cases where there are no measured data.

Towards a tactical nuclear weapons treaty? Is There a Role of IAEA Tools of Safeguards?  

SciTech Connect

In recent years, there is growing interest in formal negotiations on non-strategic or tactical nuclear weapons. With the negotiations of New START, there has been much speculation that a tactical nuclear weapons treaty should be included in the follow on to New START. This paper examines the current policy environment related to tactical weapons and some of the issues surrounding the definition of tactical nuclear weapons. We then map out the steps that would need to be taken in order to begin discussions on a tactical nuclear weapons treaty. These steps will review the potential role of the IAEA in verification of a tactical nuclear weapons treaty. Specifically, does IAEA involvement in various arms control treaties serve as a useful roadmap on how to overcome some of the issues pertaining to a tactical nuclear weapons treaty?

The UK safeguards R D program in support of the IAEA  

SciTech Connect

The concept of research and development (R D) programs in support of International Atomic Energy Agency (IAEA) safeguards arose from the mandate given to the agency to devise and implement a system of international safeguards as required by the Treaty on Non-Proliferation of Nuclear Weapons. The IAEA did not have the resources to develop the methods and techniques needed to establish and operate a system of safeguards, and it was decided that, rather than provide additional funding, the necessary R D would be carried out in voluntary programs provided by member states. The United Kingdom offered such a program in 1980, and it was formally accepted and initiated in 1981. The funding is made available by the UK government, the program being managed and the R D work performed by AEA Technology. 2 refs.

Development of a brittle fracture acceptance criterion for the International Atomic Energy Agency (IAEA)  

SciTech Connect

An effort has been undertaken to develop a brittle fracture acceptance criterion for structural components of nuclear material transportation casks. The need for such a criterion was twofold. First, new generation cask designs have proposed the use of ferritic steels and other materials to replace the austenitic stainless steel commonly used for structural components in transport casks. Unlike austenitic stainless steel which fails in a high-energy absorbing, ductile tearing mode, it is possible for these candidate materials to fail via brittle fracture when subjected to certain combinations of elevated loading rates and low temperatures. Second, there is no established brittle fracture criterion accepted by the regulatory community that covers a broad range of structural materials. Although the existing IAEA Safety Series {number_sign}37 addressed brittle fracture, its the guidance was dated and pertained only to ferritic steels. Consultant`s Services Meetings held under the auspices of the IAEA have resulted in a recommended brittle fracture criterion. The brittle fracture criterion is based on linear elastic fracture mechanics, and is the result of a consensus of experts from six participating IAEA-member countries. The brittle fracture criterion allows three approaches to determine the fracture toughness of the structural material. The three approaches present the opportunity to balance material testing requirements and the conservatism of the material`s fracture toughness which must be used to demonstrate resistance to brittle fracture. This work has resulted in a revised Appendix IX to Safety Series {number_sign}37 which will be released as an IAEA Technical Document within the coming year.

Technical results of Y-12/IAEA field trial of remote monitoring system  

SciTech Connect

A Remote Monitoring System (RMS) field trial has been conducted with the International Atomic Energy Agency (IAEA) on highly enriched uranium materials in a vault at the Oak Ridge Y-12 Plant. The RMS included a variety of Sandia, Oak Ridge, and Aquila sensor technologies which provide containment seals, video monitoring, radiation asset measurements, and container identification data to the on-site DAS (Data Acquisition System) by way of radio-frequency and Echelon LonWorks networks. The accumulated safeguards information was transmitted to the IAEA via satellite (COMSAT/RSI) and international telephone lines. The technologies tested in the remote monitoring environment are the RadCouple, RadSiP, and SmartShelf sensors from the ORSENS (Oak Ridge Sensors for Enhancing Nuclear Safeguards) technologies; the AIMS (Authenticated Item Monitoring System) motion sensor (AMS), AIMS fiber-optic seal (AFOS), ICAM (Image Compression and Authentication Module) video surveillance system, DAS (Data Acquisition System), and DIRS (Data and Image Review Station) from Sandia; and the AssetLAN identification tag, VACOSS-S seal, and Gemini digital surveillance system from Aquila. The field trial was conducted from October 1996 through May 1997. Tests were conducted during the monthly IAEA Interim Inventory Verification (IIV) inspections for evaluation of the equipment. Experience gained through the field trials will allow the technologies to be applied to various monitoring scenarios.

Approach to IAEA verification of the nuclear-material balance at the Portsmouth Gas Centrifuge Enrichment Plant (GCEP)  

SciTech Connect

This paper describes a potential approach by which the International Atomic Energy Agency (IAEA) might verify the nuclear-material balance at the Portsmouth Gas Centrifuge Enrichment Plant (GCEP), should that plant be placed under IAEA safeguards. The strategy makes use of the attributes and variables measurement verification approach, whereby the IAEA would perform independent measurements on a randomly selected subset of the items comprising the U-235 flows and inventories at the plant. In addition, the MUF-D statistic is used as the test statistics for the detection of diversion. The paper includes descriptions of the potential verification activities, as well as calculations of (a) attributes and variables sample sizes for the various strata, (b) standard deviations of the relevant test statistics, and (c) the sensitivity for detection of diversion which the IAEA might achieve by this verification strategy at GCEP.

Seal Wire Integrity Verification Instrument: Evaluation of Laboratory Prototypes  

SciTech Connect

Tamper indicating devices (TIDs) provide evidence that sensitive items, to which they have been applied, have been tampered with or not. Passive wire-loop seals, a class of TIDs, are generally comprised of a multi-strand seal wire that is threaded through or around key features and a unique seal body that captures and restrains the seal wire. Seal integrity resides with unique identification of the seal and the integrity of the seal body and the seal wire. Upon inspection, the seal wire may be cut and the full length inspected. A new seal may be applied in the field as a replacement, if desired. Seal wire inspection typically requires visual and tactile examinations, which are both subjective. A need therefore exists to develop seal wire inspection technology that is easy to use in the field, is objective, provides an auditable data trail, and has low error rates. Expected benefits, if successfully implemented, are improved on-site inspection reliability and security. The work scope for this effort was restricted to integrity of seal wire used by the International Atomic Energy Agency (IAEA) and resulted in development of a wire integrity verification instrument (WIVI) laboratory prototype. Work included a performance evaluation of a laboratory-bench-top system, and design and delivery of two WIVI laboratory prototypes. The paper describes the basic physics of the eddy current measurement, a description of the WIVI laboratory prototype, and an initial evaluation performed by IAEA personnel. --- Funding was provided by the U.S. Program for Technical Assistance to IAEA Safeguards (POTAS).

Laboratory accreditation  

SciTech Connect

Accreditation can offer many benefits to a testing or calibration laboratory, including increased marketability of services, reduced number of outside assessments, and improved quality of services. Compared to ISO 9000 registration, the accreditation process includes a review of the entire quality system, but in addition a review of testing or calibration procedures by a technical expert and participation in proficiency testing in the areas of accreditation. Within the DOE, several facilities have recently become accredited in the area of calibration, including Sandia National Laboratories, Oak Ridge, AlliedSignal FM and T; Lockheed Martin Idaho Technologies Co., and Pacific Northwest National Lab. At the national level, a new non-profit organization was recently formed called the National Cooperation for Laboratory Accreditation (NACLA). The goal of NACLA is to develop procedures, following national and international requirements, for the recognition of competent accreditation bodies in the US. NACLA is a voluntary partnership between the public and private sectors with the goal of a test or calibration performed once and accepted world wide. The NACLA accreditation body recognition process is based on the requirements of ISO Guide 25 and Guide 58. A membership drive will begin some time this fall to solicit organizational members and an election of a permanent NACLA Board of Directors will follow later this year or early 1999.

The Development of Low-Level Measurement Capabilities for Total and Isotopic Uranium in Environmental Samples at Brazilian and Argentine Laboratories by ABACC  

SciTech Connect

In June 1998, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), with assistance from the U.S. Department of Energy (DOE), began a program to assess environmental sampling and analysis capabilities at laboratories in Argentina and Brazil. The program began with staff training conducted in South America and the United States by Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL). Both laboratories are participating members of DOE’s Network of Analytical Laboratories (NWAL) that support IAEA’s environmental sampling program. During the initial planning meeting, representatives from ABACC and all the participating analytical laboratories supporting ABACC were briefed on how the first exercise would be managed and on key aspects necessary to analyze low-level environmental samples for uranium. Subsequent to this training, a laboratory evaluation exercise (Exercise 1) was conducted using standard swipe samples prepared for this exercise by the International Atomic Energy Agency (IAEA). The results of Exercise 1 determined that sample contamination was a major factor in the analysis, and a thorough review of laboratory procedures was required to reduce the level of contamination to acceptable levels. Following modification of sample preparation procedures, the laboratories performed Exercise 2, an analysis of a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 1547, Peach Leaves. The results of Exercise 2 demonstrated that several laboratories were capable of accurately determining the total uranium and uranium isotopic distribution in the peach leaves. To build on these successes, Exercise 3 was performed using a series of standard swipe samples prepared by the IAEA and distributed to laboratories supporting ABACC and to PNNL and ORNL. The results of Exercise 3 demonstrate that ABACC now has support laboratories in both Argentina and Brazil, which are capable of accurately measuring both the quantity and isotopic composition of uranium at the levels expected in typical environmental samples (i.e., nanogram quantities).

International Conference on Advances in Radiation Oncology (ICARO): outcomes of an IAEA meeting.  

PubMed

The IAEA held the International Conference on Advances in Radiation Oncology (ICARO) in Vienna on 27-29 April 2009. The Conference dealt with the issues and requirements posed by the transition from conventional radiotherapy to advanced modern technologies, including staffing, training, treatment planning and delivery, quality assurance (QA) and the optimal use of available resources. The current role of advanced technologies (defined as 3-dimensional and/or image guided treatment with photons or particles) in current clinical practice and future scenarios were discussed.ICARO was organized by the IAEA at the request of the Member States and co-sponsored and supported by other international organizations to assess advances in technologies in radiation oncology in the face of economic challenges that most countries confront. Participants submitted research contributions, which were reviewed by a scientific committee and presented via 46 lectures and 103 posters. There were 327 participants from 70 Member States as well as participants from industry and government. The ICARO meeting provided an independent forum for the interaction of participants from developed and developing countries on current and developing issues related to radiation oncology.

Experiences using IAEA Code of practice for radiation sterilization of tissue allografts: Validation and routine control  

NASA Astrophysics Data System (ADS)

Problems of tissue allografts in using International Standard (ISO) 11137 for validation of radiation sterilization dose (RSD) are limited and low numbers of uniform samples per production batch, those are products obtained from one donor. Allograft is a graft transplanted between two different individuals of the same species. The minimum number of uniform samples needed for verification dose (VD) experiment at the selected sterility assurance level (SAL) per production batch according to the IAEA Code is 20, i.e., 10 for bio-burden determination and the remaining 10 for sterilization test. Three methods of the IAEA Code have been used for validation of RSD, i.e., method A1 that is a modification of method 1 of ISO 11137:1995, method B (ISO 13409:1996), and method C (AAMI TIR 27:2001). This paper describes VD experiments using uniform products obtained from one cadaver donor, i.e., cancellous bones, demineralized bone powders and amnion grafts from one life donor. Results of the verification dose experiments show that RSD is 15.4 kGy for cancellous and demineralized bone grafts and 19.2 kGy for amnion grafts according to method A1 and 25 kGy according to methods B and C.

Measurement of (226)Ra in soil from oil field: Advantages of ?-ray spectrometry and application to the IAEA-448 CRM.  

PubMed

The analytical performance of gamma-ray spectrometry for the measurement of (226)Ra in TENORM (Technically Enhanced Naturally Occurring Radioactive Material) soil was investigated by the IAEA. Fast results were obtained for characterization and certification of a new TENORM Certified Reference Material (CRM), identified as IAEA-448 (soil from oil field). The combined standard uncertainty of the gamma-ray spectrometry results is of the order of 2-3% for massic activity measurement values ranging from 16500Bqkg(-1) to 21500Bqkg(-1). Methodologies used for the production and certification of the IAEA-448 CRM are presented. Analytical results were confirmed by alpha spectrometry. The "t" test showed agreement between alpha and gamma results at 95% confidence level. PMID:24332337

Laboratory investigations  

NASA Technical Reports Server (NTRS)

Laboratory studies related to cometary grains and the nuclei of comets can be broken down into three areas which relate to understanding the spectral properties, the formation mechanisms, and the evolution of grains and nuclei: (1) Spectral studies to be used in the interpretation of cometary spectra; (2) Sample preparation experiments which may shed light on the physical nature and history of cometary grains and nuclei by exploring the effects on grain emissivities resulting from the ways in which the samples are created; and (3) Grain processing experiments which should provide insight on the interaction of cometary grains with the environment in the immediate vicinity of the cometary nucleus as the comet travels from the Oort cloud through perihelion, and perhaps even suggestions regarding the relationship between interstellar grains and cometary matter. A summary is presented with a different view of lab experiments than is found in the literature, concentrating on measurement techniques and sample preparations especially relevant to cometary dust.

Virtual Laboratory  

NSDL National Science Digital Library

The website for the Virtual Laboratory contains a bold and direct statement: "Conventional teaching all too often accepts memorization and pattern recognition as true learning" After reading this statement, it makes sense that the goal of this site is "to help students to recognize, confront, correct, and expand their understanding of subject or a technique." The site contains five different sets of course materials that use interactive materials, short quizzes, and embedded demonstrations to assist students and teachers alike. One set of materials that should not be missed is in the Teaching & Learning Biology area. Here visitors will find links, fact sheets, and pedagogical suggestions for teaching a college-level biology course. Moving on, the Chemistry, Life, the Universe and Everything section contains a new perspective on how to reform the garden-variety general chemistry course.

Laboratory Simulations  

NASA Astrophysics Data System (ADS)

Geophysical properties of near-Earth objects (NEOs) can best be studied using radio tomography and seismology. Reflection and transmission radio tomography is best suited for measuring the complex electric permittivity of poorly conducting materials to reveal the internal structure of NEOs. Such NEOs are primarily comet nuclei and carbonaceous asteroids. Seismic experiments are most suitable for studying elastic properties of consolidated materials to reveal material strengths of stony and iron-nickel asteroids. Thus, the two methods are complementary for investigating comets and asteroids of all types. Analysis of reflection and transmission radio tomography of heterogeneous irregular shaped bodies is very difficult. Scattering by internal and outer boundaries, differences in the refractive indices of heterogeneous materials, and attenuation by electric conductivity complicate the analyses. For this reason laboratory simulations with scaled objects and scaled wavelengths is extremely useful to check the reliability of inversion techniques of radio signals to arrive at the interior structure of an NEO. Another approach to obtaining quantitative information on the composition and structure of an NEO is through induced seismology. There are two approaches to producing seismic waves: small explosive charges and impactors. Experimental work has been performed in the laboratory to examine the impulse delivered by explosives. Wave travel times can be used to back out basic material properties and first order structure of an NEO. For example, if distinct arrival pulses for P and S waves are recorded and the explosive initiation/impact time and location are known, then it is possible to determine the elastic properties of bulk and shear modulus. Reflections in the seismograms allow a determination of material boundaries in an NEO. Original arrival time is important since Q numbers for stony NEO material are presumed to be high, as they were on the Moon, and thus it is expected that there will be extensive ringing and noise. Other types of NEO materials will have differing seismic characteristics.

Intercomparison in cytogenetic dosimetry among five laboratories from Latin America.  

PubMed

As part of a regional International Atomic Energy Agency (IAEA) collaborative project within Latin America, five countries participated in an intercomparison in cytogenetic dosimetry. Coded slides for chromosomal aberrations and micronucleus analyses were prepared by the coordinator laboratory which organized the exercise and sent to the other participating laboratories. For estimates of dose, each laboratory scored the frequency of dicentrics in metaphases and the frequency of micronuclei in binucleated cells. The lymphocytes were irradiated with 60Co gamma-rays (0, 0.75, 1.5 and 3.0 Gy). Eleven of the 15 estimates of dose based on dicentrics and nine of the 12 based on micronuclei fell within +/- 30% of the true dose. When considering the uncertainties of the dose estimates, the true dose fell within the 95% confidence limits of the estimates on eight of the 15 occasions for dicentrics and four of the 12 for micronuclei.

Analysis of IAEA Environmental Samples for Plutonium and Uranium by ICP/MS in Support Of International Safeguards  

SciTech Connect

A method for the separation and determination of total and isotopic uranium and plutonium by ICP-MS was developed for IAEA samples on cellulose-based media. Preparation of the IAEA samples involved a series of redox chemistries and separations using TRU® resin (Eichrom). The sample introduction system, an APEX nebulizer (Elemental Scientific, Inc), provided enhanced nebulization for a several-fold increase in sensitivity and reduction in background. Application of mass bias (ALPHA) correction factors greatly improved the precision of the data. By combining the enhancements of chemical separation, instrumentation and data processing, detection levels for uranium and plutonium approached high attogram levels.

Using Process Load Cell Information for IAEA Safeguards at Enrichment Plants  

SciTech Connect

Uranium enrichment service providers are expanding existing enrichment plants and constructing new facilities to meet demands resulting from the shutdown of gaseous diffusion plants, the completion of the U.S.-Russia highly enriched uranium downblending program, and the projected global renaissance in nuclear power. The International Atomic Energy Agency (IAEA) conducts verification inspections at safeguarded facilities to provide assurance that signatory States comply with their treaty obligations to use nuclear materials only for peaceful purposes. Continuous, unattended monitoring of load cells in UF{sub 6} feed/withdrawal stations can provide safeguards-relevant process information to make existing safeguards approaches more efficient and effective and enable novel safeguards concepts such as information-driven inspections. The IAEA has indicated that process load cell monitoring will play a central role in future safeguards approaches for large-scale gas centrifuge enrichment plants. This presentation will discuss previous work and future plans related to continuous load cell monitoring, including: (1) algorithms for automated analysis of load cell data, including filtering methods to determine significant weights and eliminate irrelevant impulses; (2) development of metrics for declaration verification and off-normal operation detection ('cylinder counting,' near-real-time mass balancing, F/P/T ratios, etc.); (3) requirements to specify what potentially sensitive data is safeguards relevant, at what point the IAEA gains on-site custody of the data, and what portion of that data can be transmitted off-site; (4) authentication, secure on-site storage, and secure transmission of load cell data; (5) data processing and remote monitoring schemes to control access to sensitive and proprietary information; (6) integration of process load cell data in a layered safeguards approach with cross-check verification; (7) process mock-ups constructed to provide simulated load cell data; (8) hardware and software implementation for process load cell data collection; (9) costs associated with unattended monitoring of load cells (for both operator and inspector) weighed against the potential benefits of having access to such data; (10) results from field tests of load cell data collection systems in operating facilities; and (11) use of unattended load cell data to increase efficiency of on-site inspection schedules and activities.

The FAO/IAEA DGIS Coordinated research programmes on trypanosomiasis diagnosis and animal production in Africa.  

PubMed

During the period 1987-1992, Professor Dick Zwart played a key role in guiding the work of two African research networks established by the Joint FAO/IAEA Division and supported financially by the Netherlands Directorate General of Development Co-operation. These networks brought together staff from African institutes involved in the diagnosis and control of trypanosomiasis and in animal production, with scientists from International Agricultural Research Centres and other advanced research institutions in the Netherlands and elsewhere. Through this approach, the value of recently-developed immunoassay methods was assessed for diagnosing trypanosomiasis and monitoring control programmes, and similar methods were used to monitor animal productivity and ways of improving this on small-holder farms. Furthermore it strengthened the portion together with the functioning of the national agriculture research institutions. This paper outlines the main technical and other accomplishments of these networks. PMID:8372426

Review of the International Atomic Energy Agency International database on reactor pressure vessel materials and US Nuclear Regulatory Commission/Oak Ridge National Laboratory embrittlement data base  

SciTech Connect

The International Atomic Energy Agency (IAEA) has supported neutron radiation effects information exchange through meetings and conferences since the mid-1960s. Through an International Working Group on Reliability of Reactor Pressure Components, information exchange and research activities were fostered through the Coordinated Research Program (CRP) sponsored by the IAEA. The final CRP meeting was held in November 1993, where it was recommended that the IAEA coordinate the development of an International Database on Reactor Pressure Vessel Material (IDRPVM) as the first step in generating an International Database on Aging Management. The purpose of this study was to provide special technical assistance to the NRC in monitoring and evaluating the IAEA activities in developing the IAEA IDRPVM, and to compare the IDRPVM with the Nuclear Regulatory Commission (NRC) - Oak Ridge National Laboratory (ORNL) Power Reactor Embrittlement Data Base (PR-EDB) and provide recommendations for improving the PR-EDB. A first test version of the IDRPVM was distributed at the First Meeting of Liaison Officers to the IAEA IDRPVM, in November 1996. No power reactor surveillance data were included in this version; the testing data were mainly from CRP Phase III data. Therefore, because of insufficient data and a lack of power reactor surveillance data received from the IAEA IDRPVM, the comparison is made based only on the structure of the IDRPVM. In general, the IDRPVM and the EDB have very similar data structure and data format. One anticipates that because the IDRPVM data will be collected from so many different sources, quality assurance of the data will be a difficult task. The consistency of experimental test results will be an important issue. A very wide spectrum of material characteristics of RPV steels and irradiation environments exists among the various countries. Hence the development of embrittlement prediction models will be a formidable task. 4 refs., 2 figs., 4 tabs.

Numerical modeling of the radionuclide water pathway with HYDRUS and comparison with the IAEA model of SR 44.  

PubMed

This study depicts a theoretical experiment in which the radionuclide transport through the porous material of a landfill consisting of concrete rubble (e.g., from the decommissioning of nuclear power plants) and the subsequent migration through the vadose zone and aquifer to a model well is calculated by means of the software HYDRUS-1D (Simunek et al., 2008). The radionuclides originally contained within the rubble become dissolved due to leaching caused by infiltrated rainwater. The resulting well-water contamination (in Bq/L) is calculated numerically as a function of time and location and compared with the outcome of a simplified analytic model for the groundwater pathway published by the IAEA (2005). Identical model parameters are considered. The main objective of the present work is to evaluate the predictive capacity of the more simple IAEA model using HYDRUS-1D as a reference. For most of the radionuclides considered (e.g., ¹²?I, and ²³?Pu), results from applying the IAEA model were found to be comparable to results from the more elaborate HYDRUS modeling, provided the underlying parameter values are comparable. However, the IAEA model appears to underestimate the effects resulting from, for example, high nuclide mobility, short half-life, or short-term variations in the water infiltration. The present results indicate that the IAEA model is suited for screening calculations and general recommendation purposes. However, the analysis of a specific site should be accompanied by detailed HYDRUS computer simulations. In all models considered, the calculation outcome largely depends on the choice of the sorption parameter K(d). PMID:22230022

Strengthened IAEA Safeguards-Imagery Analysis: Geospatial Tools for Nonproliferation Analysis  

SciTech Connect

This slide presentation focuses on the growing role and importance of imagery analysis for IAEA safeguards applications and how commercial satellite imagery, together with the newly available geospatial tools, can be used to promote 'all-source synergy.' As additional sources of openly available information, satellite imagery in conjunction with the geospatial tools can be used to significantly augment and enhance existing information gathering techniques, procedures, and analyses in the remote detection and assessment of nonproliferation relevant activities, facilities, and programs. Foremost of the geospatial tools are the 'Digital Virtual Globes' (i.e., GoogleEarth, Virtual Earth, etc.) that are far better than previously used simple 2-D plan-view line drawings for visualization of known and suspected facilities of interest which can be critical to: (1) Site familiarization and true geospatial context awareness; (2) Pre-inspection planning; (3) Onsite orientation and navigation; (4) Post-inspection reporting; (5) Site monitoring over time for changes; (6) Verification of states site declarations and for input to State Evaluation reports; and (7) A common basis for discussions among all interested parties (Member States). Additionally, as an 'open-source', such virtual globes can also provide a new, essentially free, means to conduct broad area search for undeclared nuclear sites and activities - either alleged through open source leads; identified on internet BLOGS and WIKI Layers, with input from a 'free' cadre of global browsers and/or by knowledgeable local citizens (a.k.a.: 'crowdsourcing'), that can include ground photos and maps; or by other initiatives based on existing information and in-house country knowledge. They also provide a means to acquire ground photography taken by locals, hobbyists, and tourists of the surrounding locales that can be useful in identifying and discriminating between relevant and non-relevant facilities and their associated infrastructure. The digital globes also provide highly accurate terrain mapping for better geospatial context and allow detailed 3-D perspectives of all sites or areas of interest. 3-D modeling software (i.e., Google's SketchUp6 newly available in 2007) when used in conjunction with these digital globes can significantly enhance individual building characterization and visualization (including interiors), allowing for better assessments including walk-arounds or fly-arounds and perhaps better decision making on multiple levels (e.g., the best placement for International Atomic Energy Agency (IAEA) video monitoring cameras).

Recent IAEA Initiatives in Groundwater Dating And Their Role in Improving Water Resources Assessment and Availability  

NASA Astrophysics Data System (ADS)

Groundwater is an increasingly important source of freshwater for domestic and irrigation use. A substantial portion of groundwater supplies are from fossil groundwater that is mostly non-renewable. Fossil groundwater also contributes to baseflow of rivers and may be a more important component of river flow under changing climate regimes. Yet, the assessments of groundwater recharge, groundwater-surface water interactions, and fossil water aquifers remain poorly understood. These assessments can be effectively conducted with isotope age dating of groundwater, which may be the only means of building relevant information in many instances. A lack of easy access to analytical facilities and discordant ages estimated from multiple isotope tracers have been two of the important impediments in the wider use of age dating. We have recently established a helium isotope facility at the IAEA to increase the availability of groundwater ages for shallow aquifers and river baseflow. We have used the tritium-helium isotope pair in a river in Austria to demonstrate the applicability of noble gas isotopes for baseflow age dating. In the Nubian Aquifer system in northern Africa, many of the samples contain C-14 to levels around 10 pMC, while Kr-81 and Cl-36 ages demonstrate an age of several hundred thousands of years. Carbon-14 data collected prior to the advent of accelerator mass spectrometry is subject to large uncertainties because of potentially large contamination with atmospheric carbon dioxide during ampling. We have re-evaluated this source of contamination and found carbon-14 values of 2 pMC (by AMS) and 13 pMC (by precipitation/liquid scintillation counter) in duplicate samples from the same well. Carbon-14 values of 10 mPC or less in the Nubian Aquifer and similar aquifers that were not measured using the AMS technique are likely to be due to atmospheric contamination during water sampling. The re-evaluated Nubian groundwater age data have been used along with a 3-D groundwater model to demonstrate an effective application of isotope data for assessing the groundwater dynamics of large, fossil water aquifer such as the Nubian. This presentation will discuss these and related IAEA initiatives in the field of isotope age dating of groundwater and assessment of groundwater resources.

Development and Validation of an Atmospheric Dispersion Model for Tritium Using the IAEA Biomass Scenario  

SciTech Connect

In order to predict tritium concentration at ground level near a nuclear site, a conceivable process for tritium transfer in the natural ecosystem must be traced. We developed an Easy Evaluation System for Atmospheric Dispersion (EESAD) code based on the random walk method (RWM) for calculation of the atmospheric dispersion of tritium. The code can deal with the hourly change of weather conditions and tritium release rates as are mainly observed in an accidental release. In order to validate its prediction accuracy, and to verify its effectiveness, we calculated using scenario 3 (constant release) and scenario 4.2 (intermittent release)supplied by BIOMASS (Biosphere Modeling and Assessment) program by IAEA. Tritium concentrations predicted by EESAD calculation agreed well with those observed. Tritium deposition from the plume (dry and wet), re-emission from the soil surface, and infiltration to the lower soil layers were all considered in the EESAD system, and found to be effective to get better agreement. The EESAD is useful for calculating not only a controlled constant release with meteorological changes but also an instantaneous release with hourly changes of the release conditions.

Lessons from UNSCOM and IAEA regarding remote monitoring and air sampling  

SciTech Connect

In 1991, at the direction of the United Nations Security Council, UNSCOM and IAEA developed plans for On-going Monitoring and Verification (OMV) in Iraq. The plans were accepted by the Security Council and remote monitoring and atmospheric sampling equipment has been installed at selected sites in Iraq. The remote monitoring equipment consists of video cameras and sensors positioned to observe equipment or activities at sites that could be used to support the development or manufacture of weapons of mass destruction, or long-range missiles. The atmospheric sampling equipment provides unattended collection of chemical samples from sites that could be used to support the development or manufacture of chemical weapon agents. To support OMV in Iraq, UNSCOM has established the Baghdad Monitoring and Verification Centre. Imagery from the remote monitoring cameras can be accessed in near-real time from the Centre through RIF communication links with the monitored sites. The OMV program in Iraq has implications for international cooperative monitoring in both global and regional contexts. However, monitoring systems such as those used in Iraq are not sufficient, in and of themselves, to guarantee the absence of prohibited activities. Such systems cannot replace on-site inspections by competent, trained inspectors. However, monitoring similar to that used in Iraq can contribute to openness and confidence building, to the development of mutual trust, and to the improvement of regional stability.

SciTech Connect

The U.S. Nonproliferation and Export Control Policy, announced by President Clinton before the United Nations General Assembly on September 27, 1993, commits the U.S. to placing under International Atomic Energy Agency (IAEA) Safeguards excess nuclear materials no longer needed for the U.S. nuclear deterrent. As of July 1, 1995, the IAEA had completed Initial Physical Inventory Verification (IPIV) at two facilities: a storage vault in the Oak Ridge Y-12 plant containing highly enriched uranium (HOW) metal and another storage vault in the Hanford Plutonium Finishing Plant (PFP) containing plutonium oxide and plutonium-bearing residues. Another plutonium- storage vault, located at Rocky Flats, is scheduled for the IPIV in the fall of 1995. Conventional neutron coincidence counting is one of the routinely applied IAEA nondestructive assay (ND) methods for verification of uranium and plutonium. However, at all three facilities mentioned above, neutron ND equipment had to be modified or developed for specific facility needs such as the type and configuration of material placed under safeguards. This document describes those modifications and developments.

Sample Vial Secure Container  

SciTech Connect

International Atomic Energy Agency (IAEA) inspectors must maintain continuity of knowledge on all safeguard samples and, in particular, on those samples drawn from plutonium product and spent fuel input tanks at a nuclear reprocessing plant`s blister sampling station. Integrity of safeguard samples must be guaranteed from the sampling point to the moment of sample analysis at an accepted local laboratory or at the IAEA`s Safeguards Analytical Laboratory (SAL) in Seibersdorf, Austria. The safeguard samples are drawn at a blister sampling station with inspector participation and then transferred via a pneumatic post system to the facility`s analytical laboratory. Transfer of the sample by the pneumatic post system, arrival of the sample in the operator`s analytical laboratory, and storage of the sample awaiting analysis are very time consuming activities for an inspector, particularly if continuous human surveillance is required for all these activities. These activities could be observed by ordinary surveillance methods, such as a video monitoring system, but this would be cumbersome and time consuming for both the inspector and the operator. This paper describes a secure container designed to assure sample vial integrity from the point the sample is drawn to treatment of the sample at a facility`s analytical laboratory.

PREFACE: 11th IAEA Technical Meeting on H-mode Physics and Transport Barriers  

NASA Astrophysics Data System (ADS)

This volume of Journal of Physics: Conference Series contains papers based on invited talks and contributed posters presented at the 11th IAEA Technical Meeting on H-mode Physics and Transport Barriers. This meeting was held at the Tsukuba International Congress Center in Tsukuba, Japan, on 26-28 September 2007, and was organized jointly by the Japan Atomic Energy Agency and the University of Tsukuba. The previous ten meetings in this series were held in San Diego (USA) 1987, Gut Ising (Germany) 1989, Abingdon (UK) 1991, Naka (Japan) 1993, Princeton (USA) 1995, Kloster Seeon (Germany) 1997, Oxford (UK) 1999, Toki (Japan) 2001, San Diego (USA) 2003, and St Petersburg (Russia) 2005. The purpose of the eleventh meeting was to present and discuss new results on H-mode (edge transport barrier, ETB) and internal transport barrier, ITB, experiments, theory and modeling in magnetic fusion research. It was expected that contributions give new and improved insights into the physics mechanisms behind high confinement modes of H-mode and ITBs. Ultimately, this research should lead to improved projections for ITER. As has been the tradition at the recent meetings of this series, the program was subdivided into six topics. The topics selected for the eleventh meeting were: H-mode transition and the pedestal-width Dynamics in ETB: ELM threshold, non-linear evolution and suppression, etc Transport relations of various quantities including turbulence in plasmas with ITB: rotation physics is especially highlighted Transport barriers in non-axisymmetric magnetic fields Theory and simulation on transport barriers Projections of transport barrier physics to ITER For each topic there was an invited talk presenting an overview of the topic, based on contributions to the meeting and on recently published external results. The six invited talks were: A Leonard (GA, USA): Progress in characterization of the H-mode pedestal and L-H transition N Oyama (JAEA, Japan): Progress and issues in physics understanding of dynamics, mitigation and control of ELMs J Rice (MIT, USA): Spontaneous rotation and momentum transport in tokamak plasmas K Ida (NIFS, Japan): Transport barriers in non-axisymmetric magnetic fields F Jenko (IPP, Germany): Transport barriers: Recent progress in theory and simulation T Hoang (CEA, France): Internal transport barriers: Projection to ITER Every talk satisfied the objective of the meeting. A discussion period followed each invited talk in order to expand physics understandings, projection capabilities, and the direction of research around the topic. Short talks were presented by contributing speakers in addition to questions, answers, comments and discussion among the participants. For each topic there was an associated poster session for contributed papers, and lively discussion took place in front of every poster. Through the meeting six invited papers and 77 contributed papers were presented in total. The final session of the meeting was devoted to summaries; R Groebner, T S Hahm and K Ida of the IAC summarized the fruits of topics 1 and 2, 3 and 5, and 4 and 6, respectively. I would like to thank Dr A Malaquias, the IAEA Scientific Secretary, for his continuous support and useful suggestions on the arrangements of the meeting. I am very grateful to the IAC members for their cooperation in selecting topics and invited speakers, and for their important advices on the meeting strategy and proceedings publication. I also wish to express my gratitude to LOC colleagues for their hard work organizing the meeting. Young students of the University of Tsukuba helped us during the meeting. Financial and personel support from JAEA and the University of Tsukuba were essential. Finally I would like to acknowledge the participants of the meeting and the referees for the present proceedings. All of the above contributions contributed to the success of the meeting.

Fuel Cycle Analysis Framework Base Cases for the IAEA/INPRO GAINS Collaborative Project  

SciTech Connect

Thirteen countries participated in the Collaborative Project GAINS “Global Architecture of Innovative Nuclear Energy Systems Based on Thermal and Fast Reactors Including a Closed Fuel Cycle”, which was the primary activity within the IAEA/INPRO Program Area B: “Global Vision on Sustainable Nuclear Energy” for the last three years. The overall objective of GAINS was to develop a standard framework for assessing future nuclear energy systems taking into account sustainable development, and to validate results through sample analyses. This paper details the eight scenarios that constitute the GAINS framework base cases for analysis of the transition to future innovative nuclear energy systems. The framework base cases provide a reference for users of the framework to start from in developing and assessing their own alternate systems. Each base case is described along with performance results against the GAINS sustainability evaluation metrics. The eight cases include four using a moderate growth projection and four using a high growth projection for global nuclear electricity generation through 2100. The cases are divided into two sets, addressing homogeneous and heterogeneous scenarios developed by GAINS to model global fuel cycle strategies. The heterogeneous world scenario considers three separate nuclear groups based on their fuel cycle strategies, with non-synergistic and synergistic cases. The framework base case analyses results show the impact of these different fuel cycle strategies while providing references for future users of the GAINS framework. A large number of scenario alterations are possible and can be used to assess different strategies, different technologies, and different assumptions about possible futures of nuclear power. Results can be compared to the framework base cases to assess where these alternate cases perform differently versus the sustainability indicators.

CONFERENCE REPORT: Summary of the 8th IAEA Technical Meeting on Fusion Power Plant Safety  

NASA Astrophysics Data System (ADS)

Reports were presented covering a selection of topics on the safety of fusion power plants. These included a review on licensing studies developed for ITER site preparation surveying common and non-common issues (i.e. site dependent) as lessons to a broader approach for fusion power plant safety. Several fusion power plant models, spanning from accessible technology to more advanced-materials based concepts, were discussed. On the topic related to fusion-specific technology, safety studies were reported on different concepts of breeding blanket modules, tritium handling and auxiliary systems under normal and accident scenarios' operation. The testing of power plant relevant technology in ITER was also assessed in terms of normal operation and accident scenarios, and occupational doses and radioactive releases under these testings have been determined. Other specific safety issues for fusion have also been discussed such as availability and reliability of fusion power plants, dust and tritium inventories and component failure databases. This study reveals that the environmental impact of fusion power plants can be minimized through a proper selection of low activation materials and using recycling technology helping to reduce waste volume and potentially open the route for its reutilization for the nuclear sector or even its clearance into the commercial circuit. Computational codes for fusion safety have been presented in support of the many studies reported. The on-going work on establishing validation approaches aiming at improving the prediction capability of fusion codes has been supported by experimental results and new directions for development have been identified. Fusion standards are not available and fission experience is mostly used as the framework basis for licensing and target design for safe operation and occupational and environmental constraints. It has been argued that fusion can benefit if a specific fusion approach is implemented, in particular for materials selection which will have a large impact on waste disposal and recycling and in the real limits of radiation releases if indexed to the real impact on individuals and the environment given the differences in the types of radiation emitted by tritium when compared with the fission products. Round table sessions resulted in some common recommendations. The discussions also created the awareness of the need for a larger involvement of the IAEA in support of fusion safety standards development.

Progress and status of the IAEA coordinated research project: production of Mo-99 using LEU fission or neutron activation  

SciTech Connect

Since late 2004, the IAEA has developed and implemented a Coordinated Research Project (CRP) to assist countries interested in initiating indigenous, small-scale production of Mo-99 to meet local nuclear medicine requirements. The objective of the CRP is to provide interested countries with access to non-proprietary technologies and methods to produce Mo-99 using LEU foil or LEU mini-plate targets, or for the utilization of n,gamma neutron activation, e.g. through the use of gel generators. The project has made further progress since the RERTR 2006 meeting, with a Technical Workshop on Operational Aspects of Mo99 Production held 28-30 November 2006 in Vienna and the Second Research Coordination Meeting held in Bucharest, Romania 16-20 April 2007. The paper describes activities carried out as noted above, and as well as the provision of LEU foils to a number of participants, and the progress by a number of groups in preparing for LEU target assembly and disassembly, irradiation, chemical processing, and waste management. The participants' progress in particular on thermal hydraulics computations required for using LEU targets is notable, as also the progress in gel generator plant operations in India and Kazakhstan. Poland has joined as a new research agreement holder and an application by Egypt to be a contract holder is undergoing internal review in the IAEA and is expected to be approved. The IAEA has also participated in several open meetings of the U.S. National Academy of Sciences Study on Producing Medical Radioisotopes without HEU, which will also be discussed in the paper.

Dosimetric inter-institutional comparison in European radiotherapy centres: Results of IAEA supported treatment planning system audit.  

PubMed

Abstract Background and purpose. One of the newer audit modalities operated by the International Atomic Energy Agency (IAEA) involves audits of treatment planning systems (TPS) in radiotherapy. The main focus of the audit is the dosimetry verification of the delivery of a radiation treatment plan for three-dimensional (3D) conformal radiotherapy using high energy photon beams. The audit has been carried out in eight European countries - Estonia, Hungary, Latvia, Lithuania, Serbia, Slovakia, Poland and Portugal. The corresponding results are presented. Material and methods. The TPS audit reviews the dosimetry, treatment planning and radiotherapy delivery processes using the 'end-to-end' approach, i.e. following the pathway similar to that of the patient, through imaging, treatment planning and dose delivery. The audit is implemented at the national level with IAEA assistance. The national counterparts conduct the TPS audit at local radiotherapy centres through on-site visits. TPS calculated doses are compared with ion chamber measurements performed in an anthropomorphic phantom for eight test cases per algorithm/beam. A set of pre-defined agreement criteria is used to analyse the performance of TPSs. Results. TPS audit was carried out in 60 radiotherapy centres. In total, 190 data sets (combination of algorithm and beam quality) have been collected and reviewed. Dosimetry problems requiring interventions were discovered in about 10% of datasets. In addition, suboptimal beam modelling in TPSs was discovered in a number of cases. Conclusions. The TPS audit project using the IAEA methodology has verified the treatment planning system calculations for 3D conformal radiotherapy in a group of radiotherapy centres in Europe. It contributed to achieving better understanding of the performance of TPSs and helped to resolve issues related to imaging, dosimetry and treatment planning. PMID:24164104

Integrated monitoring technology developments at Los Alamos National Laboratory  

SciTech Connect

Los Alamos National Laboratory staff have participated in the development and installation of unattended monitoring systems in facilities in Europe, North America, Asia, and Central Asia. These systems were designed to respond to needs generated by safeguards inspectors and plant operators to have around-the-clock inspection capabilities. The unattended monitoring systems in support of International Atomic Energy Agency (IAEA) safeguards require that the inspectors visit the facilities at intervals of 1-3 months rather than having a continuous presence. A first generation of instruments and software was developed to instrument facilities from approximately 1988-1996 and is still in use today. This paper describes a second generation of instrumentation and software now under development at Los Alamos to meet the increased needs of the end users. 6 refs., 4 figs.

Comprehensive inter-laboratory calibration of reference materials for delta18O versus VSMOW using various on-line high-temperature conversion techniques.  

PubMed

Internationally distributed organic and inorganic oxygen isotopic reference materials have been calibrated by six laboratories carrying out more than 5300 measurements using a variety of high-temperature conversion techniques (HTC)a in an evaluation sponsored by the International Union of Pure and Applied Chemistry (IUPAC). To aid in the calibration of these reference materials, which span more than 125 per thousand, an artificially enriched reference water (delta(18)O of +78.91 per thousand) and two barium sulfates (one depleted and one enriched in (18)O) were prepared and calibrated relative to VSMOW2b and SLAP reference waters. These materials were used to calibrate the other isotopic reference materials in this study, which yielded: Reference material delta(18)O and estimated combined uncertainty IAEA-602 benzoic acid+71.28 +/- 0.36 per thousand USGS 35 sodium nitrate+56.81 +/- 0.31 per thousand IAEA-NO-3 potassium nitrate+25.32 +/- 0.29 per thousand IAEA-601 benzoic acid+23.14 +/- 0.19 per thousand IAEA-SO-5 barium sulfate+12.13 +/- 0.33 per thousand NBS 127 barium sulfate+8.59 +/- 0.26 per thousand VSMOW2 water 0 per thousand IAEA-600 caffeine-3.48 +/- 0.53 per thousand IAEA-SO-6 barium sulfate-11.35 +/- 0.31 per thousand USGS 34 potassium nitrate-27.78 +/- 0.37 per thousand SLAP water-55.5 per thousand The seemingly large estimated combined uncertainties arise from differences in instrumentation and methodology and difficulty in accounting for all measurement bias. They are composed of the 3-fold standard errors directly calculated from the measurements and provision for systematic errors discussed in this paper. A primary conclusion of this study is that nitrate samples analyzed for delta(18)O should be analyzed with internationally distributed isotopic nitrates, and likewise for sulfates and organics. Authors reporting relative differences of oxygen-isotope ratios (delta(18)O) of nitrates, sulfates, or organic material should explicitly state in their reports the delta(18)O values of two or more internationally distributed nitrates (USGS 34, IAEA-NO-3, and USGS 35), sulfates (IAEA-SO-5, IAEA-SO-6, and NBS 127), or organic material (IAEA-601 benzoic acid, IAEA-602 benzoic acid, and IAEA-600 caffeine), as appropriate to the material being analyzed, had these reference materials been analyzed with unknowns. This procedure ensures that readers will be able to normalize the delta(18)O values at a later time should it become necessary.The high-temperature reduction technique for analyzing delta(18)O and delta(2)H is not as widely applicable as the well-established combustion technique for carbon and nitrogen stable isotope determination. To obtain the most reliable stable isotope data, materials should be treated in an identical fashion; within the same sequence of analyses, samples should be compared with working reference materials that are as similar in nature and in isotopic composition as feasible.

The impact of the International Atomic Energy Agency (IAEA) program on radiation and tissue banking in India.  

PubMed

The banking of tissues such bone and skin began in India in the 1980s and 1990s. Although eye banking started in 1945 there was little progress in this field for the next five decades. As part of the IAEA/RCA program to use ionising radiation for the sterilisation of biological tissues in Asia and the Pacific Region, the Tata Memorial Hospital (TMH) in 1986 decided to set up a tissue bank in Mumbai funded by the Government of India. The TMH Tissue Bank became operational in January 1988, and stands as a pioneering effort in the country to provide safe, clinically useful and cost-effective human allografts for transplantation. It uses the IAEA International Standards on Tissue Banking. All the grafts are sterilised terminally by exposure to a dose of 25 kGy of gamma radiation, which has been validated as recommended by the IAEA Code of Practice for the Radiation Sterilisation of Tissues Allografts: Requirements for Validation and Routine Control. The TMH Tissue Bank is registered with the Maharashtra State Health Authorities, and in May 2004, it became India's first Tissue Bank to receive ISO 9001:2000 certification of its Quality Management System. From 1989 to September 2007, the TMH Tissue Bank has supplied 11,369 allografts to 310 surgeons operating in 69 hospitals in Mumbai and 56 hospitals in other parts of India. These numbers have been limited by difficulties with the retrieval of tissues from deceased donors due to inadequate resources and tissue donation policies of hospitals. As the Government of India representative in the IAEA program, the TMH Tissue Bank has promoted and co-coordinated these activities in the country and the development of tissue banks using radiation sterilisation of tissue grafts. Towards this end it has been engaged in training personnel, drawing up project proposals, and supporting the establishment of a Tissue Retrieval Centre in Mumbai. Currently it networks with the Zonal Transplant Co-ordination Centre of the Government of Maharashtra, and the newly instituted National Deceased Donor Transplantation Network, which will work with the Government of India to set up rules and regulations for organ and tissue donation and transplantation.

Fiscal year (FY) 1996 was a very good year for New Brunswick Laboratory (NBL), whose major sponsor is the Office of Safeguards and Security (NN-51) in the US Department of Energy (DOE), Office of Nonproliferation and National Security, Office of Security Affairs. Several projects pertinent to the NBL mission were completed, and NBL`s interactions with partners and customers were encouraging. Among the partners with which NBL interacted in this report period were the International Atomic Energy Agency (IAEA), NN-51. Environmental Program Group of the DOE Chicago Operations Office, International Safeguards Project Office, Waste Isolation Pilot Plant (WIPP), Ukraine Working Group, Fissile Materials Assurance Working Group, National Institute of Standards and Technology (NIST), Nuclear Regulatory Commission (NRC), Institute for Reference Materials and Measurements (IRMM) in Belgium, Brazilian/Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), Lockheed Idaho Technologies Company, and other DOE facilities and laboratories. NBL staff publications, participation in safeguards assistance and other nuclear programs, development of new reference materials, involvement in the updating and refinement of DOE documents, service in enhancing the science education of others, and other related activities enhanced NBL`s status among DOE laboratories and facilities. Noteworthy are the facts that NBL`s small inventory of nuclear materials is accurately accounted for, and, as in past years, its materials and human resources were used in peaceful nuclear activities worldwide.

The Virtual Robotics Laboratory  

SciTech Connect

The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations.

Development and validation of a model for tritium accumulation by a freshwater bivalve using the IAEA EMRAS scenarios  

SciTech Connect

A six-compartment metabolic model for tritium accumulation by bivalves was developed and validated using two observed data sets supplied in an international IAEA program for validation of environmental models, EMRAS (Environmental Modeling for Radiation Safety, 2003-2007). The data observed were presented in scenarios for model prediction of temporal change of HTO and OBT concentrations in Barnes mussels (Elliptio complanata). In the Uptake Scenario, mussels were transplanted from a site with background tritium concentrations into a lake, which has historically received tritium inputs over time from up-gradient waste management areas. Another data set was presented in the Depuration Scenario for model prediction of the temporal decrease in HTO and OBT concentrations in the mussels following transplantation from the lake into another lake with significantly lower tritium levels. The model simulation was able to reproduce the observation that the amount of hydrogen taken from sediment was very small compared with that taken from lake water. (authors)

Production and quality assurance in the SIT Africa Mediterranean fruit fly (Diptera: Tephritidae) rearing facility in South Africa  

SciTech Connect

A mass-rearing facility for Mediterranean fruit fly Ceratitis capitata (Wiedemann) was commissioned in Stellenbosch in 1999 to produce sterile male fruit flies for a sterile insect technique (SIT) project in commercial fruit orchards and vineyards in the Western Cape province of South Africa. The mass-rearing procedure was largely based on systems developed by the FAO/IAEA Agriculture and Biotechnology Laboratory, Seibersdorf, Austria. A number of genetic sexing strains were used to produce only males for release. Initial cramped rearing and quality management conditions were alleviated in 2001 with the construction of a new adult rearing room and quality control laboratory. In 2002 a comprehensive Quality Management System was implemented, and in 2003 an improved genetic sexing strain, VIENNA 8, was supplied by the FAO/IAEA Laboratory in Seibersdorf. For most of the first 3 years the facility was unable to supply the required number of sterile male Mediterranean fruit flies for the SIT program without importing sterile male pupae from another facility. From mid-2002, after the quality management system was implemented, both production and quality improved but remained below optimum. After the introduction of the VIENNA 8 genetic sexing strain, and together with an improvement in the climate control equipment, production stability, and quality assurance parameters improved substantially. The critical factors influencing production and quality were an inadequate rearing infrastructure, problems with the quality of the larval diet, and the initial absence of a quality management system. The results highlight the importance of effective quality management, the value of a stable and productive genetic sexing strain, and the necessity for a sound funding base for the mass-rearing facility.

El procedimiento de criar en masa fue en su mayor parte basado en los sistemas desarrollados por el Laboratorio de Agricultura y Biotecnologia de la FAO/IAEA, Seibersdorf, Austria. Un numero de razas que separara los sexos geneticamente fueron utilizadas para producir solo machos para la liberacion. La congestionada condicion inicial para criar las moscas y su manejo de calidad fueron aliviadas en 2001 con la construccion de un nuevo cuarto de cria para adultos y un laboratorio de control de calidad. En 2002, un Sistema de Manejo de Calidad comprensivo fue implementado, y en 2003 una raza mejorada que separa los sexos geneticamente, VIENNA 8, fue proveido por el Laboratorio de la FAO/IAEA en Seibersdorf. En la mayor parte de los primeros 3 anos la facilidad no pudo suplir el numero requerido de machos esteriles de la mosca mediterranea de la fruta para el programa de TIE sin la necesidad para importar machos esteriles de otra facilidad. Desde medio del ano de 2002, despues que el sistema de manejo de calidad fue implementado, la produccion y la calidad mejoraron pero aun quedaron por debajo del nivel optimo. Despues de la introduccion de la raza VIENNA 8 que separa los sexos geneticamente, y junto con el equipo mejorado de control de clima, la estabilidad y los parametros de seguridad de calidad mejoraron substancialmente. Los factores criticos que influyeron en la produccion y la calidad fueron la infraestructura inadecuada para criar las moscas, problemas con la calidad de la dieta para las larvas y la ausencia inicial de un sistema de manejo de calidad. Los resultados muestran claramente la importancia de un manejo efectivo de la calidad, el valor de una raza productiva que separa los sexos geneticamente y la necesidad de contar con una base solida de financimiento para la infraestructura de una cria en masa.

NGSI student activities in open source information analysis in support of the training program of the U.S. DOE laboratories for the entry into force of the additional protocol  

SciTech Connect

In 2008 a joint team from Los Alamos National Laboratory (LANL) and Brookhaven National Laboratory (BNL) consisting of specialists in training of IAEA inspectors in the use of complementary access activities formulated a training program to prepare the U.S. Doe laboratories for the entry into force of the Additional Protocol. As a major part of the support of the activity, LANL summer interns provided open source information analysis to the LANL-BNL mock inspection team. They were a part of the Next Generation Safeguards Initiative's (NGSI) summer intern program aimed at producing the next generation of safeguards specialists. This paper describes how they used open source information to 'backstop' the LANL-BNL team's effort to construct meaningful Additional Protocol Complementary Access training scenarios for each of the three DOE laboratories, Lawrence Livermore National Laboratory, Idaho National Laboratory, and Oak Ridge National Laboratory.

To mitigate this risk, the availability of inflight laboratory analysis instrumentation has been identified as an essential capability in future exploration missions. Mission architecture poses constraints on equipment and procedures that will be available to treat evidence-based medical conditions according to the Space Medicine Exploration Medical Conditions List (SMEMCL). The SMEMCL provided diagnosis and treatment for the evidence-based medical conditions and hence, a basis for developing ELA functional requirements.

Analytical laboratory quality audits  

SciTech Connect

Analytical Laboratory Quality Audits are designed to improve laboratory performance. The success of the audit, as for many activities, is based on adequate preparation, precise performance, well documented and insightful reporting, and productive follow-up. Adequate preparation starts with definition of the purpose, scope, and authority for the audit and the primary standards against which the laboratory quality program will be tested. The scope and technical processes involved lead to determining the needed audit team resources. Contact is made with the auditee and a formal audit plan is developed, approved and sent to the auditee laboratory management. Review of the auditee's quality manual, key procedures and historical information during preparation leads to better checklist development and more efficient and effective use of the limited time for data gathering during the audit itself. The audit begins with the opening meeting that sets the stage for the interactions between the audit team and the laboratory staff. Arrangements are worked out for the necessary interviews and examination of processes and records. The information developed during the audit is recorded on the checklists. Laboratory management is kept informed of issues during the audit so there are no surprises at the closing meeting. The audit report documents whether the management control systems are effective. In addition to findings of nonconformance, positive reinforcement of exemplary practices provides balance and fairness. Audit closure begins with receipt and evaluation of proposed corrective actions from the nonconformances identified in the audit report. After corrective actions are accepted, their implementation is verified. Upon closure of the corrective actions, the audit is officially closed.

Comparisons of the Codes of Practice IAEA TRS 277 and TRS 398: High Energy Photons and Electron Beams  

NASA Astrophysics Data System (ADS)

This work presents the calibration for: 6, 8, 10, 12, 14, 15 and 18 MeV electron beams, also to 6 and 15 MV photons beams. Beams that are generated by an accelerator Elekta Linac SL 18. The calibration is performed in terms of absorbed dose to water Dw. It is determined by two different protocols: the code of practice of the International Atomic Energy Agency (IAEA) TRS 277 for ionization chambers calibrated on air kerma NK, and the code of practice TRS 398 for ionization chambers calibrated on absorbed dose to water ND,W. Two independent dosimeters were used with two ionization chambers each one, respectively. The first one, a dosimeter PTW model UNIDOS with Markus type chamber (plane parallel) for electrons, and Farmer type chamber (cylindrical) for photons, both chambers calibrated in NK. The second dosimeter Scanditronix model DOSE 1 with plane parallel chamber (electrons) and cylindrical chamber (photons), both chambers calibrated in terms of ND,W. In the case of photon beams, the TPR was measured for 6 and 15 MV, also the profiles were determined in order to verify the flatness and symmetry of the beam: +/-3%. The quality for electrons beams were estimated by means of the Dmax, R80, R50 and Rp. The results obtained for the absorbed dose quotients DW,Q(dmax)277398 are: Electrons, 0.976<= DW,Q(dmax)277398<= 1.001 Photons: 1.001 <= DW,Q(dmax)277398 <= 1.003.

Laboratory investigation of hypercoagulability.  

PubMed

For many years, the laboratory investigation of patients with thrombophilia has lagged behind that of patients with bleeding diathesis. Improved understanding of the mechanisms that control and regulate coagulation, and the resultant recognition of new defects, have greatly stimulated clinical laboratory interest in this area. Assays to detect resistance to activated protein C; deficiencies of antithrombin, protein C, and protein S; and the presence of antiphospholipid antibodies are widely available and should form part of the investigation of patients that present with idiopathic thrombosis. Such a work-up will likely provide an explanation for thrombosis in 40 to 60% of patients. Abnormalities of fibrinogen and fibrinolysis may explain still more, although such defects are currently considered rare. In addition, presently unrecognized defects almost certainly exist, and the identification of such individuals will undoubtedly improve our understanding of the hemostatic mechanism. Laboratory tests to define the hypercoagulable state are continually being developed. They include whole blood coagulation and platelet function tests and novel activation markers. However, acceptance of these approaches by clinical laboratories has been slow. PMID:9579632

Tiny dust grains extracted from primitive meteorites are identified to have originated in the atmospheres of stars on the basis of their anomalous isotopic compositions. Although isotopic analysis with the ion microprobe plays a major role in the laboratory analysis of these stardust grains, many other microanalytical techniques are applied to extract the maximum amount of information.

Safety in Laboratories: Indian Scenario  

PubMed Central

Health and safety in clinical laboratories is becoming an increasingly important subject as a result of emergence of highly infectious diseases such as Hepatitis and HIV. A cross sectional study was carried out to study the safety measures being adopted in clinical laboratories of India. Heads of laboratories of teaching hospitals of India were subjected to a standardized, pretested questionnaire. Response rate was 44.8%. only 60% of laboratories had person in-charge of safety in laboratory. Seventy three percent of laboratories had safety education program regarding hazards. In 91% of laboratories staff is using protective clothing while working in laboratories. Hazardous material regulations are followed in 78% of laboratories. Regular health check ups are carried among laboratory staff in 43.4% of laboratories. Safety manual is available in 56.5% of laboratories. 73.9% of laboratories are equipped with fire extinguishers. Fume cupboards are provided in 34.7% of laboratories and they are regularly checked in 87.5% of these laboratories. In 78.26% of laboratories suitable measures are taken to minimize formation of aerosols. In 95.6% of laboratories waste is disposed off as per bio-medical waste management handling rules. Laboratory of one private medical college was accredited with NABL and safety parameters were better in that laboratory. Installing safety engineered devices apparently contributes to significant decrease in injuries in laboratories; laboratory safety has to be a part of overall quality assurance programme in hospitals. Accreditation has to be made necessary for all laboratories.

Revitalizing chemistry laboratory instruction  

NASA Astrophysics Data System (ADS)

This dissertation involves research in three major domains of chemical education as partial fulfillment of the requirements for the Ph.D. program in chemistry at Miami University with a major emphasis on chemical education, and concurrent study in organic chemistry. Unit I, Development and Assessment of a Column Chromatography Laboratory Activity, addresses the domain of Instructional Materials Development and Testing. This unit outlines the process of developing a publishable laboratory activity, testing and revising that activity, and subsequently sharing that activity with the chemical education community. A laboratory activity focusing on the separation of methylene blue and sodium fluorescein was developed to demonstrate the effects of both the stationary and mobile phase in conducting a separation. Unit II, Bringing Industry to the Laboratory, addresses the domain of Curriculum Development and Testing. This unit outlines the development of the Chemistry of Copper Mining module, which is intended for use in high school or undergraduate college chemistry. The module uses the learning cycle approach to present the chemistry of the industrial processes of mining copper to the students. The module includes thirteen investigations (three of which are web-based and ten which are laboratory experiments) and an accompanying interactive CD-ROM, which provides an explanation of the chemistry used in copper mining with a virtual tour of an operational copper mine. Unit III, An Alternative Method of Teaching Chemistry. Integrating Lecture and the Laboratory, is a project that addresses the domain of Research in Student Learning. Fundamental Chemistry was taught at Eastern Arizona College as an integrated lecture/laboratory course that met in two-hour blocks on Monday, Wednesday, and Friday. The students taking this integrated course were compared with students taking the traditional 1-hour lectures held on Monday, Wednesday, and Friday, with accompanying 3-hour lab on Tuesday or Thursday. There were 119 students in the test group, 522 students in the Shelton control group and 556 students in the McBride control group. Both qualitative data and quantitative data were collected. A t-test was used to test significance.

Local laboratory ventilation devices  

SciTech Connect

This article is a discussion of the ``other`` laboratory ventilation devices described in OSHA`s laboratory standard that could be used in lieu of traditional chemical fume hoods. The reference ``local`` or ``other`` ventilation device is used with little or no information provided as to the type, design, or performance criteria appropriate for specific applications, as was done in excruciating detail for their fume hood cousins. Equally curious is the fact that no performance test criteria were established for this category of equipment. Therefore, great care must be taken by the designer to determine the specific application intended for each unit specified and confirm that its use is appropriate for the task. In light of these standards, manufacturers have responded with many new and innovative products.

Testers and bystanders can inadvertently lead subjects to answers in laboratories and in classrooms, in face-to-face tests of human beings and other animals. Many modern investigators avoid leading by using blind tests scrupulously. This article shows how to design blind tests and illustrates common methodological errors that allow leading to confound experimental results. The object is to help experimenters, editors, and readers detect and avoid a common experimental error that often has profound theoretical implications. PMID:22324284

Laboratory Astrochemistry: Interstellar PAHs  

NASA Technical Reports Server (NTRS)

Polycyclic aromatic hydrocarbons (PAHs) are now considered to be an important and ubiquitous component of the organic material in space. PAHs are found in a large variety of extraterrestrial materials such as interplanetary dust particles (IDPs) and meteoritic materials. PAHs are also good candidates to account for the infrared emission bands (UIRs) and the diffuse interstellar optical absorption bands (DIBs) detected in various regions of the interstellar medium. The recent observations made with the Infrared Space Observatory (ISO) have confirmed the ubiquitous nature of the UIR bands and their carriers. PAHs are thought to form through chemical reactions in the outflow from carbon-rich stars in a process similar to soot formation. Once injected in the interstellar medium, PAHs are further processed by the interstellar radiation field, interstellar shocks and energetic particles. A major, dedicated, laboratory effort has been undertaken to measure the physical and chemical characteristics of these complex molecules and their ions under experimental conditions that mimic the interstellar conditions. These measurements require collision-free conditions where the molecules and ions are cold and chemically isolated. The spectroscopy of PAHs under controlled conditions represents an essential diagnostic tool to study the evolution of extraterrestrial PAHs. The Astrochemistry Laboratory program will be discussed through its multiple aspects: (1) objectives, (2) approach and techniques adopted, (3) adaptability to the nature of the problem(s), and (4) results and implications for astronomy as well as for molecular spectroscopy. A review of the data generated through laboratory simulations of space environments and the role these data have played in our current understanding of the properties of interstellar PAHs will be presented. The discussion will also introduce the newest generation of laboratory experiments that are currently being developed in order to provide a closer simulation of space environments and a better support to space missions.

Further factors for the estimation of mean glandular dose using the United Kingdom, European and IAEA breast dosimetry protocols.  

PubMed

The United Kingdom, European and IAEA protocols for breast dosimetry in mammography make use of s-factors which allow for the use of different target/filter combinations. To supplement the existing protocols, a Monte Carlo computer program has been used to calculate s-factors for mammography using a tungsten target with silver filters of thicknesses 50-75 microm and for the same target filtered with 0.5 mm aluminium. The dosimetry protocols use slabs of polymethyl methacrylate (PMMA) of specified thicknesses to simulate the exposure of typical breasts. The equivalent thickness of PMMA has been calculated using a simplified approach for a wider range of x-ray spectra and for breast thicknesses of 2-11 cm. The results show that for the tungsten/silver target/filter combination, a single s-factor of 1.042 can be used with the protocols, but when the tungsten target is filtered with 0.5 mm of aluminium, it is necessary to select from a tabulation of s-factors against breast thickness. The equivalent thicknesses of PMMA for a given breast thickness show some dependence on beam quality and the values obtained differ from those presently used in the dosimetry protocols by an amount which depends upon breast thickness and half value layer (HVL). For the extreme case of an 11 cm breast and an HVL of 0.62 mm Al, the use of the protocol thickness would give rise to an error of 10%, but for breast thicknesses of 6 cm or less, the error is typically 2-3%.

Smart Grid Integration Laboratory  

SciTech Connect

The initial federal funding for the Colorado State University Smart Grid Integration Laboratory is through a Congressionally Directed Project (CDP), DE-OE0000070 Smart Grid Integration Laboratory. The original program requested in three one-year increments for staff acquisition, curriculum development, and instrumentation â?? all which will benefit the Laboratory. This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSUâ??s overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratoryâ??s focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3) Simulation of electrical power distribution system that integrates significant quantities of renewable and distributed energy resources; (4) System dynamic modeling that considers end-user behavior, economics, security and regulatory frameworks; (5) Best practices for energy management IT control solutions for effective distributed energy integration (including security with the underlying physical power systems); (6) Experimental verification of effects of various arrangements of renewable generation, distributed generation and user load types along with conventional generation and transmission. Understanding the core technologies for enabling them to be used in an integrated fashion within a distribution network remains is a benefit to the future energy paradigm and future and present energy engineers.

Laboratory experiments and modeling for industrial radiotracer applications.  

PubMed

This paper presents three laboratory experiments, which have been carried out using the Molybdenum-99 (Mo(99)) radiotracer to measure the residence time distribution (RTD), the mixing time and the flow rate in a water flow rig. The results of the RTD measurement experiment are preprocessed using the MATLAB software for background correction, radioactive decay correction, starting point correction, filtering, and data extrapolation. After preprocessing, six mathematical models are investigated on this data using the International Atomic Energy Agency (IAEA) RTD software. The parameters of each model are optimized to calculate the value of the RTD, and to determine the model, which gives the best match with the practical data. The selected model with the best match is used to calculate the RTD in this experiment. The mixing time experiment is carried out for different rotation speeds and repeated three times in each case. The results show that the mixing time is inversely proportional to the rotation speed. The flow rate experiment is carried out to measure the flow rate in the flow rig. The experimental results show a high reliability of the radiotracer used in the RTD, mixing time and flow rate measurements. PMID:20171110

Oak Ridge National Laboratory's Preparations for Additional Protocol Implementation  

SciTech Connect

The United States Additional Protocol (AP) with the International Atomic Energy Agency (IAEA) entered into force (EIF) January 6, 2009. In anticipation of the EIF, the Department of Energy (DOE) National Nuclear Security Administration Office of International Regimes and Agreements (NA-243) began the initial DOE AP data call on November 3, 2008. This paper describes the Oak Ridge National Laboratory's (ORNL's) preparation, organization, and development efforts to successfully implement the AP and complete the AP data call. ORNL had 35 days to identify declarable activities and finalize the declaration line items (DLIs) for submission to NA-243. To be able to respond within the required time frame, many preparation activities at ORNL were necessary, such as determining the AP coordinator (APC) and team roles; conducting site awareness training; creating the ORNL Standards-Based Management System (SBMS) procedure Reporting of Nuclear Fuel Cycle Activities; training personnel; and defining site implementation software tools. Identifying, updating, compiling, reviewing, and submitting the DLIs to NA-243 were all critical activities for successfully implementing the AP and completing the AP data call at ORNL.

Purdue Hydrogen Systems Laboratory  

SciTech Connect

The Hydrogen Systems Laboratory in a unique partnership between Purdue University's main campus in West Lafayette and the Calumet campus was established and its capabilities were enhanced towards technology demonstrators. The laboratory engaged in basic research in hydrogen production and storage and initiated engineering systems research with performance goals established as per the USDOE Hydrogen, Fuel Cells, and Infrastructure Technologies Program. In the chemical storage and recycling part of the project, we worked towards maximum recycling yield via novel chemical selection and novel recycling pathways. With the basic potential of a large hydrogen yield from AB, we used it as an example chemical but have also discovered its limitations. Further, we discovered alternate storage chemicals that appear to have advantages over AB. We improved the slurry hydrolysis approach by using advanced slurry/solution mixing techniques. We demonstrated vehicle scale aqueous and non-aqueous slurry reactors to address various engineering issues in on-board chemical hydrogen storage systems. We measured the thermal properties of raw and spent AB. Further, we conducted experiments to determine reaction mechanisms and kinetics of hydrothermolysis in hydride-rich solutions and slurries. We also developed a continuous flow reactor and a laboratory scale fuel cell power generation system. The biological hydrogen production work summarized as Task 4.0 below, included investigating optimal hydrogen production cultures for different substrates, reducing the water content in the substrate, and integrating results from vacuum tube solar collector based pre and post processing tests into an enhanced energy system model. An automated testing device was used to finalize optimal hydrogen production conditions using statistical procedures. A 3 L commercial fermentor (New Brunswick, BioFlo 115) was used to finalize testing of larger samples and to consider issues related to scale up. Efforts continued to explore existing catalytic methods involving nano catalysts for capture of CO2 from the fermentation process.

Manufacturing Laboratory (Fact Sheet)  

SciTech Connect

This fact sheet describes the purpose, lab specifications, applications scenarios, and information on how to partner with NREL's Manufacturing Laboratory at the Energy Systems Integration Facility. The Manufacturing Laboratory at NREL's Energy Systems Integration Facility (ESIF) focuses on developing methods and technologies that will assist manufacturers of hydrogen and fuel cell technologies, as well as other renewable energy technologies, to scale up their manufacturing capabilities to volumes that meet DOE and industry targets. Specifically, the manufacturing activity is currently focused on developing and validating quality control techniques to assist manufacturers of low temperature and high temperature fuel cells in the transition from low to high volume production methods for cells and stacks. Capabilities include initial proof-of-concept studies through prototype system development and in-line validation. Existing diagnostic capabilities address a wide range of materials, including polymer films, carbon and catalyst coatings, carbon fiber papers and wovens, and multi-layer assemblies of these materials, as well as ceramic-based materials in pre- or post-fired forms. Work leading to the development of non-contact, non-destructive techniques to measure critical dimensional and functional properties of fuel cell and other materials, and validation of those techniques on the continuous processing line. This work will be supported by materials provided by our partners. Looking forward, the equipment in the laboratory is set up to be modified and extended to provide processing capabilities such as coating, casting, and deposition of functional layers, as well as associated processes such as drying or curing. In addition, continuous processes are used for components of organic and thin film photovoltaics (PV) as well as battery technologies, so synergies with these important areas will be explored.

NASA Astrophysics Data System (ADS)

Fred Hoyle undertook a study of observational consequences of the thermonuclear paradigm for the nova event in the years following his 1972 resignation from Cambridge University. The most fruitful of these have been in the areas of gamma-ray astronomy, by which one attempts to measure the level of radioactivity in the nova envelope, and of presolar grain studies in laboratories, by which one measures anomalous isotopic ratios that fingerprint condensation in the thermonuclear event. This work summarizes progress with these two astronomical measures of the novae.

Microgravity Emissions Laboratory Developed  

NASA Technical Reports Server (NTRS)

The Microgravity Emissions Laboratory (MEL) was developed for the support, simulation, and verification of the International Space Station microgravity environment. The MEL utilizes an inertial measurement system using acceleration emissions generated by various operating components of the space station. These emissions, if too large, could hinder the science performed on the space station by disturbing the microgravity environment. Typical test components are disk drives, pumps, motors, solenoids, fans, and cameras. These components will produce inertial forces, which disturb the microgravity on-orbit station environment. These components, usually housed within a station rack, must meet acceleration limits imposed at the rack interface for minimizing the onboard station-operating environment. The NASA Glenn Research Center developed this one-of-a-kind laboratory for testing components and, eventually, rack-level configurations. The MEL approach is to measure the component's generated inertial forces. This force is a product of the full diagonal mass matrix including the test setup (the center of gravity, mass moment of inertia, and weight) and the resolved diagonal rigid-body acceleration determined from measurements using the 10 apparatus accelerometers. The mass matrix can be test derived. The bifilar torsional pendulum method is used to measure the moment of inertia for the test component.

Mobile Energy Laboratory Procedures  

SciTech Connect

Pacific Northwest Laboratory (PNL) has been tasked to plan and implement a framework for measuring and analyzing the efficiency of on-site energy conversion, distribution, and end-use application on federal facilities as part of its overall technical support to the US Department of Energy (DOE) Federal Energy Management Program (FEMP). The Mobile Energy Laboratory (MEL) Procedures establish guidelines for specific activities performed by PNL staff. PNL provided sophisticated energy monitoring, auditing, and analysis equipment for on-site evaluation of energy use efficiency. Specially trained engineers and technicians were provided to conduct tests in a safe and efficient manner with the assistance of host facility staff and contractors. Reports were produced to describe test procedures, results, and suggested courses of action. These reports may be used to justify changes in operating procedures, maintenance efforts, system designs, or energy-using equipment. The MEL capabilities can subsequently be used to assess the results of energy conservation projects. These procedures recognize the need for centralized NM administration, test procedure development, operator training, and technical oversight. This need is evidenced by increasing requests fbr MEL use and the economies available by having trained, full-time MEL operators and near continuous MEL operation. DOE will assign new equipment and upgrade existing equipment as new capabilities are developed. The equipment and trained technicians will be made available to federal agencies that provide funding for the direct costs associated with MEL use.

Laboratory Diagnostics of Botulism  

PubMed Central

Botulism is a potentially lethal paralytic disease caused by botulinum neurotoxin. Human pathogenic neurotoxins of types A, B, E, and F are produced by a diverse group of anaerobic spore-forming bacteria, including Clostridium botulinum groups I and II, Clostridium butyricum, and Clostridium baratii. The routine laboratory diagnostics of botulism is based on the detection of botulinum neurotoxin in the patient. Detection of toxin-producing clostridia in the patient and/or the vehicle confirms the diagnosis. The neurotoxin detection is based on the mouse lethality assay. Sensitive and rapid in vitro assays have been developed, but they have not yet been appropriately validated on clinical and food matrices. Culture methods for C. botulinum are poorly developed, and efficient isolation and identification tools are lacking. Molecular techniques targeted to the neurotoxin genes are ideal for the detection and identification of C. botulinum, but they do not detect biologically active neurotoxin and should not be used alone. Apart from rapid diagnosis, the laboratory diagnostics of botulism should aim at increasing our understanding of the epidemiology and prevention of the disease. Therefore, the toxin-producing organisms should be routinely isolated from the patient and the vehicle. The physiological group and genetic traits of the isolates should be determined.

The impact of the International Atomic Energy Agency (IAEA) program on radiation and tissue banking in Mexico.  

PubMed

Tissue banking started in Mexico in 1948-1949, when two bone banks were established, one at the Infantile Hospital of Mexico and other at the Central Military Hospital. Mexico has benefited for the implementation of the IAEA program since through it has been able to settle down and to consolidate the Tissue Bank at the Instituto Nacional de Investigaciones Nucleares ININ (National Institute for Nuclear Research). This is the only bank in Latin America that has a Quality Management System in force, certified under ISO 9001:2000 since August 1, 2003. The first tissue processed was amnion. The main products of the BTR are amnion and pig skin. Both are biological tissues which their main use is as a wound dressing in patients with burns, scars, diabetic ulcers, epidermolysis bullosa, damaged ocular surface, etc. The General Health Law, published in 1984 and reformed in June 19, 2007, describes the procedure for the disposal of organs, tissues and human cadavers in its fourteenth title and in the Regulation for Sanitary Control. During the period 2001-2005, the ININ Tissue Bank produced 292 sterilised tissues (amnion, 86,668 cm(2), and frozen pig skin, 164,220 cm(2), at an estimated cost of 1,012,668 Mexican pesos. Until 2006, one hundred eighty five (185) patients have been treated with the use of sterilised tissues produced by the ININ Tissue Bank. The radiation source used for sterilisation of tissues is an industrial Cobalt-60 irradiator model JS-6500 AECL, which belongs to ININ. This equipment is located in other building, close to the BTR, in the Centro Nuclear de México "Dr. Nabor Carrillo Flores" (Nuclear Center of Mexico). Until 2006, six hospitals use in a routine way the sterilised tissues produced by the ININ Tissue Bank, for the treatment of burns originated by diverse agents like flame, electricity, liquids in boil, chemical reagents, as well as for the reconstruction of the ocular surface. Two of these hospitals treat patients of very low economic incomes, mainly needy individuals, who cannot afford to pay this type of treatments in other hospitals due to their high cost. The results obtained up to now are highly promising. PMID:18612848

The use of the internet training course modality in the field of tissue banking: the International Atomic Energy Agency (IAEA)/National University of Singapore (NUS) experience.  

PubMed

The International Atomic Energy Agency (IAEA) promoted and supported an important training program for the training of tissue bank operators and medical doctors within its radiation and tissue banking program. The purpose of the program was to train an increase number of tissue bank operators and medical doctors in Asia and the Pacific, Latin America and Eastern Europe, that were working or were associated to a number of tissue banks established in these regions under the IAEA program during the 1980s, 1990s and 2000s. The National University of Singapore Tissue Bank was designated, in 1996, as the Regional Training Centre (RTC) for Asia and the Pacific region and later on, in 2002, as the International Training Centre (ITC) for the whole IAEA program. The National Atomic Energy Commission of Argentina and the Faculty of Medicine of the University of Buenos Aires were also designated, in 1999, as the Regional Training Centre for the Latin American region. The objective of the ITC was to train tissue banks operators and medical doctors from all over the world and the RTCs to train tissue bank operators and medical doctors mainly from the Asia and the Pacific and the Latin American regions. Since 1997, training of tissue bank operators and medical doctors were carried out using the modality of distance training courses. However, due to its limitation, this type of courses was transformed, in 2002, in an Internet training course modality, with the purpose to increase not only the number of participants but, at the same time to reduce, as much as possible, the costs associated with the organisation of these courses. Since November 1997, the number of training courses carried out in the RTCs established under the IAEA program was 14, eight of them under the Internet training course modality. The total number of students registered in these courses was 261 and the total number of students graduated was 166 for a rate of approval of 63.6%. The National University of Singapore and the Faculty of Medicine from the University of Buenos Aires are the academic institutions that provide the certificate/diploma to the graduated students.

Mars Science Laboratory Drill  

NASA Technical Reports Server (NTRS)

The Drill for the Mars Science Laboratory mission is a rotary-percussive sample acquisition device with an emphasis on toughness and robustness to handle the harsh environment on Mars. The unique challenges associated with autonomous drilling from a mobile robot are addressed. A highly compressed development schedule dictated a modular design architecture that satisfies the functional and load requirements while allowing independent development and testing of the Drill subassemblies. The Drill consists of four actuated mechanisms: a spindle that rotates the bit, a chuck that releases and engages bits, a novel voice-coil-based percussion mechanism that hammers the bit, and a linear translation mechanism. The Drill has three passive mechanisms: a replaceable bit assembly that acquires and collects sample, a contact sensor / stabilizer mechanism, and, lastly a flex harness service loop. This paper describes the various mechanisms that makeup the Drill and discusses the solutions to their unique design and development challenges.

Tochilinite Produced in Laboratory  

NASA Astrophysics Data System (ADS)

Tochilinite was firstly identified in the serpentinites from Voronezh region, Russia, in 1971. Later this mineral was recognized to be a major matrix phase of the most primitive carbonaceous chondrites (CI, CM) where tochilinite as a mixed-layer structure occurs among serpentine group minerals, olivine, pyroxene, pyrrhotite etc. Terrestrial tochilinite has been suggested to result from low-temperature hydrothermal alteration of serpentinite. The origin of the chondritic tochilinite is still not known, partly because of failure to synthesis this mineral. As for as we know, since 1971, there was no publication about successful synthesis of tochilinite. Here we present results of the first laboratory synthesis of tochilinite as a product of interaction of Fe(II) hydroxides with H2S at 80 degrees C, and total concentration of reduced sulfur ions in solution lower than 10-4M at pH 7.8 and lower than 1M at pH 11.5.

An Organoleptic Laboratory Experiment  

NASA Astrophysics Data System (ADS)

Flavorings in foods and fragrances in personal care products is a topic often discussed in chemistry classes designed for the general education of non-science majors. A laboratory experiment has been designed to accompany the lecture topic. Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell. Students are permitted to create their own fragrance based on the results of the experiment. Student response has been favorable. The experiment rectifies misconceptions students have about structure and odor, and gives positive reinforcement to the lecture material.

Laboratory for Radiokrypton Dating  

NASA Astrophysics Data System (ADS)

Due to its simple production and transport processes in the terrestrial environment, the long-lived noble-gas isotope 81Kr (half-life = 230 kyr) is the ideal tracer for studying old water and ice in the age range of 10^5-10^6 years, a range beyond the reach of 14C. 81Kr dating, a concept pursued in the past four decades by numerous laboratories employing a variety of techniques, is now available for the first time to the earth science community at large. This is made possible by the development of ATTA-3 (Jiang et al., GCA 91, 1-6; 2012), an efficient and selective atom counter based on the Atom Trap Trace Analysis method (Chen et al., Science 286, 1139-1141; 1999). The instrument is capable of measuring both 81Kr/Kr and 85Kr/Kr ratios of environmental samples in the range of 10^-14-10^-10. For 81Kr-dating in the age range of 150 - 1,500 kyr, the required sample size is 5 - 10 micro-L STP of krypton gas, which can be extracted from approximately 100 - 200 kg of water or 40 - 80 kg of ice. For 85Kr/Kr analysis, the required sample size is generally smaller by an order of magnitude because of the isotope's higher initial abundance in the atmosphere. The Laboratory for Radiokrypton Dating is currently equipped to analyze up to 120 samples per year. With future equipment upgrades, this limit can be increased as demand grows. In the period since November 2011, the Laboratory has measured both 81Kr/Kr and 85Kr/Kr ratios in over 50 samples that had been extracted by collaborators from six different continents. The samples were from groundwater wells in the Great Artesian Basin (Australia), Guarani Aquifer (Brazil), and Locust Grove (Maryland); from brine wells of the Waste Isolation Pilot Plant (New Mexico); from geothermal steam vents in Yellowstone National Park; from near-surface ice at Taylor Glacier, Antarctica; and from deep mines in South Africa. Sample collection and purification was performed by groups including the University of Illinois at Chicago, University of Bern, and International Atomic Energy Agency. ATTA is a laser-based atom counting method, not a mass spectrometry method. A magneto-optical trap is used to capture neutral atoms (rather than ions) of the desired isotope using laser beams. A photo-sensor detects the laser induced fluorescence emitted by the individual trapped atoms. ATTA is unique among trace analysis techniques in that it is free of interferences from any other isotopes, isobars, atomic or molecular species. In an experiment demonstrating that ATTA-3 can analyze 39Ar/Ar ratios in environmental samples, no interference from other atomic or molecular species was observed at the 1x10^-16 level (Jiang et al., Phys. Rev. Lett. 106, 103001; 2011). This work proved the feasibility of performing 39Ar dating using the ATTA method. We are supported by DOE, Office of Nuclear Physics, under contract DE-AC02-06CH11357, and by Argonne National Laboratory.

Laminar laboratory rivers  

NASA Astrophysics Data System (ADS)

A viscous fluid flowing over fine plastic grains spontaneously channelizes into a few centimeters-wide river. After reaching its equilibrium shape, this stable laboratory flume is able to carry a steady load of sediments, like many alluvial rivers. When the sediment discharge vanishes, the river size, shape and slope fit the threshold theory proposed by Glover and Florey (1951), which assumes that the Shields parameter is critical on the channel bed. As the sediment discharge is increased, the river widens and flattens. Surprisingly, the aspect ratio of its cross section depends on the sediment discharge only, regardless of the water discharge. We propose a theoretical interpretation of these findings based on the balance between gravity, which pulls particles towards the center of the channel, and the diffusion of bedload particles, which pushes them away from areas of intense bedload.

First International Microgravity Laboratory  

NASA Technical Reports Server (NTRS)

This colorful booklet presents capsule information on every aspect of the International Microgravity Laboratory (IML). As part of Spacelab, IML is divided into Life Science Experiments and Materials Science Experiments. Because the life and materials sciences use different Spacelab resources, they are logically paired on the IML missions. Life science investigations generally require significant crew involvement, and crew members often participate as test subjects or operators. Materials missions capitalize on these complementary experiments. International cooperation consists in participation by the European Space Agency, Canada, France, Germany, and Japan who are all partners in developing hardware and experiments of IML missions. IML experiments are crucial to future space ventures, like the development of Space Station Freedom, the establishment of lunar colonies, and the exploration of other planets. Principal investigators are identified for each experiment.

EDITORIAL: Special issue containing papers presented at the 11th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems Special issue containing papers presented at the 11th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems  

NASA Astrophysics Data System (ADS)

The history of fusion research resembles the way in which one builds skyscrapers: laying the first foundation stone, one thinks about the top of the skyscraper. At the early stages of fusion, when it became clear that the thermonuclear reactor would operate with DT plasma confined by the magnetic field, the study of the `top item'—the physics of 3.5 MeV alpha particles produced by the DT fusion reaction—was initiated. The first publications on this topic appeared as long ago as the 1960s. At that time, because the physics of alpha particles was far from the experimental demand, investigations were carried out by small groups of theoreticians who hoped to discover important and interesting phenomena in this new research area. Soon after the beginning of the work, theoreticians discovered that alpha particles could excite various instabilities in fusion plasmas. In particular, at the end of the 1960s an Alfvén instability driven by alpha particles was predicted. Later it turned out that a variety of Alfvén instabilities with very different features does exist. Instabilities with perturbations of the Alfvénic type play an important role in current experiments; it is likely that they will affect plasma performance in ITER and future reactors. The first experimental manifestation of instabilities excited by superthermal particles in fusion devices was observed in the PDX tokamak in 1983. In this device a large-scale instability—the so called `fishbone instability'—associated with ions produced by the neutral beam injection resulted in a loss of a large fraction of the injected energy. Since then, the study of energetic-ion-driven instabilities and the effects produced by energetic ions in fusion plasmas has attracted the growing attention of both experimentalists and theorists. Recognizing the importance of this topic, the first conference on fusion alpha particles was held in 1989 in Kyiv under the auspices of the IAEA. The meeting in Kyiv and several subsequent meetings (Aspenäs (1991), Trieste (1993), Princeton (1995), and JET/Abingdon (1997)) were entitled `Alpha Particles in Fusion Research'. During the JET/Abingdon meeting in 1997 it was decided to extend the topic by including other suprathermal particles, in particular accelerated electrons, and rename the meetings accordingly. The subsequent meetings with the current name `Energetic Particles in Magnetic Confinement Systems' were held in Naka (1999), Gothenburg (2001), San Diego (2003), Takayama (2005) and Kloster Seeon (2007). The most recent meeting in this series was held in Kyiv, Ukraine, in September 2009. This was an anniversary meeting, 20 years after the first meeting. Like the first meeting, it was hosted by the Institute for Nuclear Research, National Academy of Sciences of Ukraine. It was attended by about 80 researchers from 18 countries, ITER, and EC. The program of the meeting consisted of 78 presentations, including 12 invited talks, 16 oral contributed talks, and 50 posters, which were selected by the International Advisory Committee (IAC). The IAC consisted of 11 people representing EC (L.-G. Eriksson), Germany (S. Günter), Italy (F. Zonca), Japan (K. Shinohara and K. Toi), Switzerland (A. Fasoli), UK (S. Sharapov), Ukraine (Ya. Kolesnichenko—IAC Chair), USA (H. Berk, W. Heidbrink, and R. Nazikian). The meeting program covered a wide range of physics issues concerning energetic ions in toroidal fusion facilities—tokamaks, stellarators, and spherical tori. Many new interesting and practically important results of both experimental and theoretical studies were reported. The research presented covered topics such as instabilities driven by energetic ions, transport of energetic ions caused by plasma microturbulence and destabilized eigenmodes, non-linear phenomena induced by the instabilities, classical transport processes, effects of runaway electrons, diagnostics of energetic ions and plasmas, and aspects of ITER physics. In addition to these topics, which were also covered at previous conferences in this series and have become conven

Laboratory testing in pharmacies.  

PubMed

Point-of-care testing (POCT) is traditionally defined as laboratory diagnostics performed at or near the site where clinical care is delivered. POCT thereby combines sample collection, analysis, and reporting of results into a robust integrated testing structure, with a simple user interface. The availability of reliable devices and consolidated tests for patient screening, diagnosis and monitoring has allowed broad diffusion of POCT to the patient's bedside, physician offices, pharmacies, other healthcare facilities, supermarkets, and even into the patient's home. However, current evidence clearly shows that POCT can be subjective, and might even amplify the traditional problems encountered in the preanalytical, analytical and postanalytical phases of the total testing process. This may especially be seen in inappropriateness of the test request, collection of unsuitable biological materials, inaccurate test performances, larger analytical imprecision, unsuitable report formatting, delayed reporting of critical value, and report recording/retrieval. POCT patient care service in the pharmacy can be regarded as a valuable option for the present and future since it might be beneficial for all parties. However, several economic, clinical and regulatory issues should also be addressed before this opportunity can turn into a real advantage for patients and the entire healthcare system. The most appropriate allocation of POCT within the diagnostic pathway, as well as its adjuvant role in screening, diagnosis and monitoring of diseases should also be clearly established in order to prevent widespread and deregulated implementation.

Laboratory diagnosis of SARS.  

PubMed Central

The emergence of new viral infections of man requires the development of robust diagnostic tests that can be applied in the differential diagnosis of acute illness, or to determine past exposure, so as to establish the true burden of disease. Since the recognition in April 2003 of the severe acute respiratory syndrome coronavirus (SARS-CoV) as the causative agent of severe acute respiratory syndrome (SARS), enormous efforts have been applied to develop molecular and serological tests for SARS which can assist rapid detection of cases, accurate diagnosis of illness and the application of control measures. International progress in the laboratory diagnosis of SARS-CoV infection during acute illness has led to internationally agreed World Health Organization criteria for the confirmation of SARS. Developments in the dissection of the human immune response to SARS indicate that serological tests on convalescent sera are essential to confirm SARS infection, given the sub-optimal predictive value of molecular detection tests performed during acute SARS illness.

BNL Sources Development Laboratory  

SciTech Connect

The NSLS has a long-standing interest in providing the best possible synchrotron radiation sources for its user community, and hence, has recently established the Source Development Laboratory (SDL) to pursue research into fourth generation synchrotron radiation sources. A major element of the program includes development of a high peak power FEL meant to operate in the vacuum ultraviolet. The objective of the program is to develop the source, and experimental technology together to provide the greatest impact on UV science. The accelerator under construction for the SDL consists of a high brightness RF photocathode electron gun followed by a 230 MeV short pulse linac incorporating a magnetic chicane for pulse compression. The gun drive laser is a wide bandwidth Ti: Sapphire regenerative amplifier capable of pulse shaping which will be used to study non- linear emittance compensation. Using the compressor, 1 nC bunches with a length as small as 50 {mu}m sigma (2 kA peak current) are available for experiments. In this paper we briefly describe the facility and detail our plans for utilizing the 10 m long NISUS wiggler to carry out single pass FEL experiments. These include a 1 {mu}m SASE demonstration, a seeded beam demonstration at 300 nm, and a High Gain Harmonic Generation experiment at 200 mn. The application of chirped pulse amplification to this type of FEL will also be discussed.

Automated Microbial Metabolism Laboratory  

NASA Technical Reports Server (NTRS)

The Automated Microbial Metabolism Laboratory (AMML) 1971-1972 program involved the investigation of three separate life detection schemes. The first was a continued further development of the labeled release experiment. The possibility of chamber reuse without inbetween sterilization, to provide comparative biochemical information was tested. Findings show that individual substrates or concentrations of antimetabolites may be sequentially added to a single test chamber. The second detection system which was investigated for possible inclusion in the AMML package of assays, was nitrogen fixation as detected by acetylene reduction. Thirdly, a series of preliminary steps were taken to investigate the feasibility of detecting biopolymers in soil. A strategy for the safe return to Earth of a Mars sample prior to manned landings on Mars is outlined. The program assumes that the probability of indigenous life on Mars is unity and then broadly presents the procedures for acquisition and analysis of the Mars sample in a manner to satisfy the scientific community and the public that adequate safeguards are being taken.

Environment for scientific laboratories  

SciTech Connect

In the past several years a number of major environment building efforts have been undertaken. Some environments that are operational are: Smalltalk, Gandalf, Interlisp, and Toolpack. The Ada Environment continues to grow steadily. Why do we need another environment. The reason is, of course, that we believe that our requirements and constraints are quite different from those for whom the above environments were designed. We believe that other installations that produce large scientific programs may have similar requirements. We also believe that environments can be assembled from software tools already in use. Software development becomes increasingly more expensive. It is important to understand how resources already in existence may be used effectively as building blocks in the creation of new systems. We currently have a number of research efforts directed towards the creation of environments. We describe an environment that is being built largely from existing software tools. Most government and scientific laboratories do not have the resources for a project as large as an environment. However, environments do not have to be built from scratch nor does one have to be built from existing tools in a bottom up manner. Ideally, in an installation that has a large body of existing tools, one can construct a chosen environment by adapting software already on hand. In this paper we describe a framework that may be used to put together software tools, a database management system, and a user interface. The result is that one can build a powerful environment with a modest support staff. We know of no other such attempt that has been made for an integrated system of this type. Our ideas for an environment framework have been realized in a particular environment we have christened Amicus in the hope that it will be our programmer's friend.

Australia's marine virtual laboratory  

NASA Astrophysics Data System (ADS)

In all modelling studies of realistic scenarios, a researcher has to go through a number of steps to set up a model in order to produce a model simulation of value. The steps are generally the same, independent of the modelling system chosen. These steps include determining the time and space scales and processes of the required simulation; obtaining data for the initial set up and for input during the simulation time; obtaining observation data for validation or data assimilation; implementing scripts to run the simulation(s); and running utilities or custom-built software to extract results. These steps are time consuming and resource hungry, and have to be done every time irrespective of the simulation - the more complex the processes, the more effort is required to set up the simulation. The Australian Marine Virtual Laboratory (MARVL) is a new development in modelling frameworks for researchers in Australia. MARVL uses the TRIKE framework, a java-based control system developed by CSIRO that allows a non-specialist user configure and run a model, to automate many of the modelling preparation steps needed to bring the researcher faster to the stage of simulation and analysis. The tool is seen as enhancing the efficiency of researchers and marine managers, and is being considered as an educational aid in teaching. In MARVL we are developing a web-based open source application which provides a number of model choices and provides search and recovery of relevant observations, allowing researchers to: a) efficiently configure a range of different community ocean and wave models for any region, for any historical time period, with model specifications of their choice, through a user-friendly web application, b) access data sets to force a model and nest a model into, c) discover and assemble ocean observations from the Australian Ocean Data Network (AODN, http://portal.aodn.org.au/webportal/) in a format that is suitable for model evaluation or data assimilation, and d) run the assembled configuration in a cloud computing environment, or download the assembled configuration and packaged data to run on any other system of the user's choice. MARVL is now being applied in a number of case studies around Australia ranging in scale from locally confined estuaries to the Tasman Sea between Australia and New Zealand. In time we expect the range of models offered will include biogeochemical models.

Laboratory detection of fungemia.  

PubMed

Patients who are immunosuppressed, receiving broad-spectrum antibiotics, or with intravascular catheters in place are at risk for invasive fungal infections. In a significant number nosocomial fungal infections develop. The diagnosis of invasive fungal disease often relies on the detection of the etiologic agent using blood cultures. Great progress has been made in fungal blood culturing over the past 20 years with the development of biphasic media, automated radiometric and nonradiometric systems, and LCS used with selective culture media. The biphasic BHI and Septi-Chek systems provide recovery of the majority of fungal isolates, yet there frequently is an undesirable delay in detection. Lysis of blood cells, aeration by venting, and agitated incubation improve detection with these systems. Automated systems often require a significant initial financial investment but have been shown to be durable and effective in most aspects of blood culturing. They have a limited daily hands on requirement. The newer nonradiometric systems appear to be better than the older systems, especially in time to detection and in the reduction of false-positive signals. The most significant factors, however, may be the volume of blood used in these systems and the resins incorporated in the media to eliminate inhibitors of fungal growth. A significant disadvantage of the automated systems has been their failure to detect certain organisms (C. neoformans and dimorphic fungi); however, the use of newer culture media as well as blind subculturing may partially alleviate this problem. Lysis-centrifugation blood culturing has performed well, is highly sensitive, and permits recovery of both fungi and aerobic bacteria. Because it is flexible, the media selection can be altered to suit any specific growth requirement. It is rapid and permits the identification of most yeast and yeastlike microorganisms within 4 days and of H. capsulatum within 3 weeks. Because this system utilizes solid media, blind subculturing is unnecessary. Quantitation of fungemia is possible and may permit determination of the clinical importance of the microorganism and assessment of the patient's response to treatment. The disadvantages of this system are that it requires a significant amount of the technologist's time to process the specimen, inoculate the various media, and visually examine the culture media throughout the incubation period. A significant contamination rate still exists despite working within a laminar flow biosafety cabinet; this also increases time requirements. The detection of fungemia has markedly improved; the times to detection have decreased to the point of being clinically useful, and several systems are available to accommodate individual laboratory needs.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:8181236

Laboratory volcano geodesy  

NASA Astrophysics Data System (ADS)

Magma transport in volcanic plumbing systems induces surface deformation, which can be monitored by geodetic techniques, such as GPS and InSAR. These geodetic signals are commonly analyzed through geodetic models in order to constrain the shape of, and the pressure in, magma plumbing systems. These models, however, suffer critical limitations: (1) the modelled magma conduit shapes cannot be compared with the real conduits, so the geodetic models cannot be tested nor validated; (2) the modelled conduits only exhibit shapes that are too simplistic; (3) most geodetic models only account for elasticity of the host rock, whereas substantial plastic deformation is known to occur. To overcome these limitations, one needs to use a physical system, in which (1) both surface deformation and the shape of, and pressure in, the underlying conduit are known, and (2) the mechanical properties of the host material are controlled and well known. In this contribution, we present novel quantitative laboratory results of shallow magma emplacement. Fine-grained silica flour represents the brittle crust, and low viscosity vegetable oil is an analogue for the magma. The melting temperature of the oil is 31°C; the oil solidifies in the models after the end of the experiments. At the time of injection the oil temperature is 50°C. The oil is pumped from a reservoir using a volumetric pump into the silica flour through a circular inlet at the bottom of a 40x40 cm square box. The silica flour is cohesive, such that oil intrudes it by fracturing it, and produces typical sheet intrusions (dykes, cone sheets, etc.). During oil intrusion, the model surface deforms, mostly by doming. These movements are measured by an advanced photogrammetry method, which uses 4 synchronized fixed cameras that periodically image the surface of the model from different angles. We apply particle tracking method to compute the 3D ground deformation pattern through time. After solidification of the oil, the intrusion can be excavated and photographed from several angles to compute its 3D shape with the same photogrammetry method. Then, the surface deformation pattern can be directly compared with the shape of underlying intrusion. This quantitative dataset is essential to quantitatively test and validate classical volcano geodetic models.

Evaluation of Calibration Laboratories Performance  

NASA Astrophysics Data System (ADS)

One of the main goals of interlaboratory comparisons (ILCs) is the evaluation of the laboratories performance for the routine calibrations they perform for the clients. In the frame of Accreditation of Laboratories, the national accreditation boards (NABs) in collaboration with the national metrology institutes (NMIs) organize the ILCs needed to comply with the requirements of the international accreditation organizations. In order that an ILC is a reliable tool for a laboratory to validate its best measurement capability (BMC), it is needed that the NMI (reference laboratory) provides a better traveling standard—in terms of accuracy class or uncertainty—than the laboratories BMCs. Although this is the general situation, there are cases where the NABs ask the NMIs to evaluate the performance of the accredited laboratories when calibrating industrial measuring instruments. The aim of this article is to discuss the existing approaches for the evaluation of ILCs and propose a basis for the validation of the laboratories measurement capabilities. An example is drafted with the evaluation of the results of mercury-in-glass thermometers ILC with 12 participant laboratories.

Testing containment of laboratory hoods  

SciTech Connect

Laboratory fume hoods often do not adequately provide protection to a chemist or technician at the hood. The reason for failure of the hoods to perform adequately are varied and, in many instances, difficult to determine. In some cases, the laboratory hood manufacturer has provided equipment that does not reflect the state of art in controlling laboratory exposures. In other cases, the architect or engineer has disregarded the function of the hood thus the design of the installation is faulty and the hood will not work. The contractor may have installed the system so poorly that it will not adequately function. Finally, the chemist or technician may misuse the hood, causing poor performance. This paper considers a method of evaluating the performance of laboratory fume hoods. Using the method, the paper examines several instances where the laboratory fume hood performed inadequately, quantifies the performance and identifies the cause of poor performance.

Mars Science Laboratory Drill  

NASA Technical Reports Server (NTRS)

This drill (see Figure 1) is the primary sample acquisition element of the Mars Science Laboratory (MSL) that collects powdered samples from various types of rock (from clays to massive basalts) at depths up to 50 mm below the surface. A rotary-percussive sample acquisition device was developed with an emphasis on toughness and robustness to handle the harsh environment on Mars. It is the first rover-based sample acquisition device to be flight-qualified (see Figure 2). This drill features an autonomous tool change-out on a mobile robot, and novel voice-coil-based percussion. The drill comprises seven subelements. Starting at the end of the drill, there is a bit assembly that cuts the rock and collects the sample. Supporting the bit is a subassembly comprising a chuck mechanism to engage and release the new and worn bits, respectively, and a spindle mechanism to rotate the bit. Just aft of that is a percussion mechanism, which generates hammer blows to break the rock and create the dynamic environment used to flow the powdered sample. These components are mounted to a translation mechanism, which provides linear motion and senses weight-on-bit with a force sensor. There is a passive-contact sensor/stabilizer mechanism that secures the drill fs position on the rock surface, and flex harness management hardware to provide the power and signals to the translating components. The drill housing serves as the primary structure of the turret, to which the additional tools and instruments are attached. The drill bit assembly (DBA) is a passive device that is rotated and hammered in order to cut rock (i.e. science targets) and collect the cuttings (powder) in a sample chamber until ready for transfer to the CHIMRA (Collection and Handling for Interior Martian Rock Analysis). The DBA consists of a 5/8-in. (.1.6- cm) commercial hammer drill bit whose shank has been turned down and machined with deep flutes designed for aggressive cutting removal. Surrounding the shank of the bit is a thick-walled maraging steel collection tube allowing the powdered sample to be augured up the hole into the sample chamber. For robustness, the wall thickness of the DBA was maximized while still ensuring effective sample collection. There are four recesses in the bit tube that are used to retain the fresh bits in their bit box. The rotating bit is supported by a back-to-back duplex bearing pair within a housing that is connected to the outer DBA housing by two titanium diaphragms. The only bearings on the drill in the sample flow are protected by a spring-energized seal, and an integrated shield that diverts the ingested powdered sample from the moving interface. The DBA diaphragms provide radial constraint of the rotating bit and form the sample chambers. Between the diaphragms there is a sample exit tube from which the sample is transferred to the CHIMRA. To ensure that the entire collected sample is retained, no matter the orientation of the drill with respect to gravity during sampling, the pass-through from the forward to the aft chamber resides opposite to the exit tube.

Trial of integrated laboratory practice.  

PubMed

In most laboratory practices for students in medical schools, a laboratory guidebook is given to the students, in which the procedures are precisely described. The students merely follow the guidebook without thinking deeply, which spoils the students and does not entice them to think creatively. Problem-based learning (PBL) could be one means for the students themselves to actively learn, find problems, and resolve them. Such a learning attitude nurtures medical students with lifelong learning as healthcare professionals. We merged PBL and laboratory practices to promote deep thinking habits and developed an integrated laboratory practice. We gave a case sheet to groups of students from several schools. The students raised hypotheses after vivid discussion, designed experimental protocols, and performed the experiments. If the results did not support or disproved the hypothesis, the students set up another hypothesis followed by experiments, lasting for 4 or 5 consecutive days. These procedures are quite similar to those of professional researchers. The main impact achieved was the fact that the students developed the experimental design by themselves, for the first time in their college lives. All students enjoyed the laboratory practice, which they had never experienced before. This is an antidote to the guidebook-navigated traditional laboratory practice, which disappoints many students. As educators in basic medical sciences stand on the edge in terms of educating the next generation, there is a need to provide a strong foundation for medical students to design and perform scientific experiments. The integrated laboratory practice may provide the solution. PMID:21652510

Clinical laboratory accreditation in India.  

PubMed

Test results from clinical laboratories must ensure accuracy, as these are crucial in several areas of health care. It is necessary that the laboratory implements quality assurance to achieve this goal. The implementation of quality should be audited by independent bodies,referred to as accreditation bodies. Accreditation is a third-party attestation by an authoritative body, which certifies that the applicant laboratory meets quality requirements of accreditation body and has demonstrated its competence to carry out specific tasks. Although in most of the countries,accreditation is mandatory, in India it is voluntary. The quality requirements are described in standards developed by many accreditation organizations. The internationally acceptable standard for clinical laboratories is ISO15189, which is based on ISO/IEC standard 17025. The accreditation body in India is the National Accreditation Board for Testing and Calibration Laboratories, which has signed Mutual Recognition Agreement with the regional cooperation the Asia Pacific Laboratory Accreditation Cooperation and with the apex cooperation the International Laboratory Accreditation Cooperation.

During the 20th century understanding for quality has changed and international and national requirements for quality have been published. Therefore also medical branches started to establish quality management systems. Quality assurance has always been important for medical laboratories. Certification according to the standard ISO 9001 and accreditation according to the standard ISO 17025 have been the proof of fulfilling quality requirements. The relatively new standard ISO 15189 is the first standard for medical laboratories. This standard includes technical and management requirements for the medical laboratory. The main focus is the proof of competence within the personnel. As this standard is accepted throughout the European Union an increase in accreditations of medical laboratories is predictable.

[Coding for clinical laboratory information].  

PubMed

The field of clinical laboratory tests is facing an increase in the number of test items as well as a corresponding diversification due to the demands of medical institutions as well as improvements in analytical techniques. To respond to this situation, medical institutions have been promoting systematization of their testing procedures; information exchange among the institutions has likewise expanded with the use of media such as on-line systems and internet. Standardization of interfaces has been proposed to secure a common framework compatible with different types of information. Some embodiments in this country includes; (1) Interface Standards on Clinical Laboratory Information For information exchange, the format and reporting comments used in the media systems were standardized under the sponsorship of The Medical Information System Development Center, with a publication issued on 1993. (2) Standardization of Laboratory Test Code Standardization of codes for information exchange has been established under the sponsorship of The Japan Society of Clinical Pathology (Laboratory Test Coding Committee), through the systematization of laboratory test code used in media systems. A publication entitled "Classification & Coding for Clinical Laboratory Tests (8th edition in 1992, 9th edition in 1994 and supplement in 1996)" has been issued. The system for "Classification & Coding for Clinical Laboratory Tests" is divided into 5 components; (1) analyte code, (2) identification code, (3) specimen code, (4) methodology code, and (5) data classification code. The Laboratory test codes are precisely classified by "(1) analyte code", and then are identified by combination of additional codes such as specimen and methodology codes.

Commercialization of a DOE Laboratory  

SciTech Connect

On April 1, 1998, Materials and Chemistry Laboratory, Inc. (MCLinc) began business as an employee-owned, commercial, applied research laboratory offering services to both government and commercial clients. The laboratory had previously been a support laboratory to DoE's gaseous diffusion plant in Oak Ridge (K-25). When uranium enrichment was halted at the site, the laboratory was expanded to as an environmental demonstration center and served from 1992 until 1997 as a DOE Environmental User Facility. In 1997, after the laboratory was declared surplus, it was made available to the employee group who operated the laboratory for DOE as a government-owned, contractor-operated facility. This paper describes briefly the process of establishing the business. Attributes that contributed to the success of MCLinc are described. Some attention is given to lessons learned and to changes that could facilitate future attempts to make similar transitions. Lessons learnt: as with any business venture, operation over time has revealed that some actions taken by the laboratory founders have contributed to its successful operation while others were not so successful. Observations are offered in hopes that lessons learned may suggest actions that will facilitate future attempts to make similar transitions. First, the decision to vest significant ownership of the business in the core group of professionals operating the business is key to its success. Employee-owners of the laboratory have consistently provided a high level of service to its customers while conducting business in a cost-efficient manner. Secondly, an early decision to provide business support services in-house rather than purchasing them from support contractors on site have proven cost-effective. Laboratory employees do multiple tasks and perform overhead tasks in addition to their chargeable technical responsibilities. Thirdly, assessment of technical capabilities in view of market needs and a decision to offer these capabilities as a niche market play to success. The niche was further defined by preservation of the ability to handle samples contaminated with radiological materials and those with classification concerns. These decisions enabled early marketing plans to be built on existing clientele and provided an identifiable group to which future marketing could be expanded. Finally, recruitment of key players with commercial laboratory experience proved to be a key factor for success. This experience base was valuable in avoiding early mistakes in the laboratory startup phase and provided some connection to a commercial client base. As the business has grown, professionals with commercial laboratory experience have been recruited and offered ownership in the business as an incentive for joining the group. If the process were to be repeated, early involvement of an individual with commercial sales experience would be helpful in broadening the base of commercial clients. An increased emphasis on research funding such as funding received from Small Business Innovative Research (SBIR) sources would be used to form a portion of the economic base for the business. More partnerships with businesses whose services compliment those of the laboratory would expand available client base. More flexible staffing arrangements would be negotiated early on as a cost-control measure. In conclusion, the re-industrialization concept can be successful. Candidates for re-industrialization must be chosen by matching services to be offered to market needs. Implementation is best accomplished by entrepreneurs who personally profit from a successful operation of the business.

Laboratory monitoring of new anticoagulants.  

PubMed

Maintaining a balance between bleeding and clotting has always been a challenge in treating coagulation disorders. A perturbation in that balance can be associated with substantial morbidity and mortality. As a result, anticoagulant monitoring is extremely important, and inappropriate testing may lead to complications. There are now a variety of new anticoagulant drugs in clinical use including several direct thrombin inhibitors (DTIs), such as argatroban, bivalirudin, and hirudin, as well as a Factor Xa inhibitor, fondaparinux. There are pitfalls associated with some of the currently used laboratory monitoring tests, and newer alternative laboratory monitoring tests have been investigated (Walenga and Hoppensteadt, Semin Thromb Hemost 2004;30:683-695). In addition, laboratory testing can assist with transitioning patients from DTI to warfarin therapy. PMID:20131309

Laboratory aspects of Lyme borreliosis.  

PubMed Central

Lyme borreliosis (Lyme disease), a common tick-borne disorder of people and domestic animals in North America and Europe, is caused by the spirochete Borrelia burgdorferi. Following the discovery and initial propagation of this agent in 1981 came revelations that other tick-associated infectious disorders are but different forms of Lyme borreliosis. A challenge for the clinician and microbiology laboratory is confirmation that a skin rash, a chronic meningitis, an episode of myocarditis, or an arthritic joint is the consequence of B. burgdorferi infection. The diagnosis of Lyme borreliosis may be established by (i) directly observing the spirochete in host fluid or tissue, (ii) recovering the etiologic spirochete from the patient in culture medium or indirectly through inoculation of laboratory animals, or (iii) carrying out serologic tests with the patient's serum or cerebrospinal fluid. The last method, while lacking in discriminatory power, is the most efficacious diagnostic assay for most laboratories at present. Images

Multicellular microorganisms: laboratory versus nature  

PubMed Central

Our present in-depth knowledge of the physiology and regulatory mechanisms of microorganisms has arisen from our ability to remove them from their natural, complex ecosystems into pure liquid cultures. These cultures are grown under optimized laboratory conditions and allow us to study microorganisms as individuals. However, microorganisms naturally grow in conditions that are far from optimal, which causes them to become organized into multicellular communities that are better protected against the harmful environment. Moreover, this multicellular existence allows individual cells to differentiate and acquire specific properties, such as forming resistant spores, which benefit the whole population. The relocation of natural microorganisms to the laboratory can result in their adaptation to these favourable conditions, which is accompanied by complex changes that include the repression of some protective mechanisms that are essential in nature. Laboratory microorganisms that have been cultured for long periods under optimized conditions might therefore differ markedly from those that exist in natural ecosystems.

Laboratory maintenance of Neisseria gonorrhoeae.  

PubMed

Neisseria gonorrhoeae is a human pathogen of mucosal surfaces, thus laboratory manipulations must include appropriate safety measures. The growth requirements and behavior of the gonococcus are significantly different from many bacteria, necessitating modifications of common laboratory techniques. A fastidious organism, N. gonorrhoeae requires enriched media in a CO2 atmosphere at 35 degrees to 37 degrees C for growth. In addition, N. gonorrhoeae expresses potent autolysins whose activity increases following glucose depletion during stationary phase, leading to cell death. Long believed to be an obligate aerobe, the gonococcus is capable of anaerobic growth when provided with a suitable electron acceptor. This unit provides information for both aerobic and anaerobic growth, basic long-term and daily maintenance of gonococcal cultures, as well as safety considerations for laboratory studies.

Alerting of Laboratory Critical Values  

NASA Astrophysics Data System (ADS)

Critical value is defined as a result suggesting that the patient is in danger unless appropriate action is taken immediately. We designed an automated reporting system of critical values and evaluated its performance. Fifteen critical values were defined and 2-4 doctors were assigned to receive short message service (SMS).Laboratory results in LIS and EMR were called back to the DIA server. The rule engine named U-brain in the CDSS server was run in real-time and decision if the laboratory data was critical was made. The CDSS system for alerting of laboratory critical values was fast and stable without additional burden to the entire EMR system. Continuous communication with clinicians and feedback of clinical performance are mandatory for the refinement and development of user-friendly CDSS contents. Appropriate clinical parameters are necessary for demonstration of the usefulness of the system.

Virtual Laboratories and Virtual Worlds  

NASA Astrophysics Data System (ADS)

Since we cannot put stars in a laboratory, astrophysicists had to wait till the invention of computers before becoming laboratory scientists. For half a century now, we have been conducting experiments in our virtual laboratories. However, we ourselves have remained behind the keyboard, with the screen of the monitor separating us from the world we are simulating. Recently, 3D on-line technology, developed first for games but now deployed in virtual worlds like Second Life, is beginning to make it possible for astrophysicists to enter their virtual labs themselves, in virtual form as avatars. This has several advantages, from new possibilities to explore the results of the simulations to a shared presence in a virtual lab with remote collaborators on different continents. I will report my experiences with the use of Qwaq Forums, a virtual world developed by a new company (see http://www.qwaq.com).

Laboratory Astrophysics White Paper: Summary of Laboratory Astrophysics Needs  

NASA Technical Reports Server (NTRS)

The NASA Laboratory Astrophysics Workshop (NASA LAW) met at NASA Ames Research Center from 1-3 May 2002 to assess the role that laboratory astrophysics plays in the optimization of NASA missions, both at the science conception level and at the science return level. Space missions provide understanding of fundamental questions regarding the origin and evolution of galaxies, stars, and planetary systems. In all of these areas the interpretation of results from NASA's space missions relies crucially upon data obtained from the laboratory. We stress that Laboratory Astrophysics is important not only in the interpretation of data, but also in the design and planning of future missions. We recognize a symbiosis between missions to explore the universe and the underlying basic data needed to interpret the data from those missions. In the following we provide a summary of the consensus results from our Workshop, starting with general programmatic findings and followed by a list of more specific scientific areas that need attention. We stress that this is a 'living document' and that these lists are subject to change as new missions or new areas of research rise to the fore.

Materials Characterization Laboratory (Fact Sheet)  

SciTech Connect

This fact sheet describes the purpose, lab specifications, applications scenarios, and information on how to partner with NREL's Materials Characterization Laboratory at the Energy Systems Integration Facility. The Materials Characterization Laboratory at NREL's Energy Systems Integration Facility (ESIF) research focus is the physical and photoelectrochemical characterization of novel materials. In this laboratory unknown samples are characterized by identifying and quantifying molecular species present through the implementation of a suite of analytical instrumentation and techniques. This leads to the ability to deconvolute decomposition routes and elucidate reaction mechanisms of materials through thermal and evolved gas analysis. This aids in the synthesis of next generation materials that are tailored to optimize stability and performance. These techniques and next generation materials will have many applications. One particular focus is the stable and conductive tetherable cations for use as membrane materials in anion exchange membrane fuel cells. Another is to understand the leachant contaminants derived from balance of plant materials used in proton exchange membrane fuel cell vehicles. Once identified and quantified, these organic and ionic species are dosed as contaminants into ex/in-situ fuel cell tests, to determine the effect on durability and performance. This laboratory also acts in support of fuel cell catalysis, manufacturing, and other related projects. The Materials Characterization Laboratory will cover multiple analytical operations, with the overall goal of troubleshooting synthetic materials or process streams to improve performance. Having novel evolved gas analysis and other analytical capabilities; this laboratory provides a viable location to analyze small batch samples, whereas setting up these types of capabilities and expertise would be cost and time prohibitive for most institutions. Experiments that can be performed include: (1) Evolved gas analysis; (2) Heterogeneous catalysis; (3) Trace level contaminants analysis; (4) Catalyst characterization; (5) Kinetics and stability; (6) Hyphenated techniques; and (7) Isotopic analysis for elucidating reaction mechanisms and decoupling chemical reactions.

Exploration Laboratory Analysis FY13  

NASA Technical Reports Server (NTRS)

The Exploration Laboratory Analysis (ELA) project supports the Exploration Medical Capability (ExMC) risk, which is stated as the Risk of Inability to Adequately Treat an Ill or Injured Crew Member, and ExMC Gap 4.05: Lack of minimally invasive in-flight laboratory capabilities with limited consumables required for diagnosing identified Exploration Medical Conditions. To mitigate this risk, the availability of inflight laboratory analysis instrumentation has been identified as an essential capability in future exploration missions. Mission architecture poses constraints on equipment and procedures that will be available to treat evidence-based medical conditions according to the Space Medicine Exploration Medical Conditions List (SMEMCL), and to perform human research studies on the International Space Station (ISS) that are supported by the Human Health and Countermeasures (HHC) element. Since there are significant similarities in the research and medical operational requirements, ELA hardware development has emerged as a joint effort between ExMC and HHC. In 2012, four significant accomplishments were achieved towards the development of exploration laboratory analysis for medical diagnostics. These achievements included (i) the development of high priority analytes for research and medical operations, (ii) the development of Level 1 functional requirements and concept of operations documentation, (iii) the selection and head-to-head competition of in-flight laboratory analysis instrumentation, and (iv) the phase one completion of the Small Business Innovation Research (SBIR) projects under the topic Smart Phone Driven Blood-Based Diagnostics. To utilize resources efficiently, the associated documentation and advanced technologies were integrated into a single ELA plan that encompasses ExMC and HHC development efforts. The requirements and high priority analytes was used in the selection of the four in-flight laboratory analysis performers. Based upon the competition results, a down select process will be performed in the upcoming year. Looking ahead, this unified effort has positioned each element for an in-flight lab analysis demonstration of select diagnostics measurements in the 2015 timeframe.

Federal laboratories for the 21st century  

SciTech Connect

Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

CBRN mobile laboratories in Italy  

NASA Astrophysics Data System (ADS)

The paper describes the experiences in Italy with the CBRN (Chemical Biological Radiological Nuclear) defense mobile laboratories. These laboratories were constructed by the Italian Army and the Italian Fire Brigades. The purpose of these mobile laboratories is to allow quick transport of the labs to the area of crisis in order to support emergency response in case of CBRN events. The differences between two alternative solutions will be developed in the paper. The first solution is when the lab is to be located in the "dangerous area" (this solution was chosen by the Italian Army) and the alternative approach is to place the mobile lab just outside the dangerous area (this approach was selected by the Italian Fire Brigades). One of the most important devices inside the lab is the isolator (also called "glove box") which allows safe ingress and handling of the "suspicious" samples from the external environment. The isolator has a special chamber for transfer of the sample from the outside. The pressure of the isolator is permanently kept below the air pressure inside the lab by means of one (or more) fan. The operators perform the sample preparations or part of the analysis by handling the sample with the gloves. The material flow inside the lab will be described depending on the kind of identification analysis to be done on the samples. Other devices installed on the mobile CBRN laboratories are: biohazard hood (UE regulation, containment level 2); autoclave; freezer; cleaning skid (tanks, pumps, etc.).

Aeroshell for Mars Science Laboratory  

NASA Technical Reports Server (NTRS)

This image from July 2008 shows the aeroshell for NASA's Mars Science Laboratory while it was being worked on by spacecraft technicians at Lockheed Martin Space Systems Company near Denver.

This hardware was delivered in early fall of 2008 to NASA's Jet Propulsion Laboratory, Pasadena, Calif., where the Mars Science Laboratory spacecraft is being assembled and tested.

The aeroshell encapsulates the mission's rover and descent stage during the journey from Earth to Mars and shields them from the intense heat of friction with that upper atmosphere during the initial portion of descent.

The aeroshell has two main parts: the backshell, which is on top in this image and during the descent, and the heat shield, on the bottom. The heat shield in this image is an engineering unit for testing. The heat shield to be used in flight will be substituted later. The heat shield has a diameter of about 15 feet. For comparison, the heat shields for NASA's Mars Exploraton Rovers Spirit and Opportunity were 8.5 feet and the heat shields for the Apollo capsules that protected astronauts returning to Earth from the moon were just under 13 feet.

In addition to protecting the Mars Science Laboratory rover, the backshell provides structural support for the descent stage's parachute and sky crane, a system that will lower the rover to a soft landing on the surface of Mars. The backshell for the Mars Science Laboratory is made of an aluminum honeycomb structure sandwiched between graphite-epoxy face sheets. It is covered with a thermal protection system composed of a cork/silicone super light ablator material that originated with the Viking landers of the 1970s. This ablator material has been used on the heat shields of all NASA Mars landers in the past, but this mission is the first Mars mission using it on the backshell.

The heat shield for Mars Science Laboratory's flight will use tiles made of phenolic impregnated carbon ablator. The engineering unit in this image does not have the tiles.

SciTech Connect

The results of an international comparison calculation of a large (1250 MWe) LMFBR benchmark model are presented and discussed. Eight reactor configurations were calculated. Parameters included with the comparison were: eigenvalue, k/sub infinity/, neutron balance data, breeding reaction rate ratios, reactivity worths, central control rod worth, regional sodium void reactivity, core Doppler and effective delayed neutron fraction. Ten countries participated in the comparison, and sixteen solutions were contributed. The discussion focuses on the variation in parameter values, the degree of consistency among the various parameters and solutions, and the identification of unexpected results. The results are displayed and discussed both by individual participants and by groupings of participants (e.g., results from adjusted data sets versus non-adjusted data sets).
