Zooplankton of the waters adjacent to the C. P. Crane generating station. Final report  

SciTech Connect

Zooplankton population in the Gunpowder River and its tributaries were sampled monthly from July, 1979-March, 1980 in a continuation of similar studies begun in March, 1979. The objective of the study was to determine the effect of the present once-through cooling system of the Crane Power Plant. The principal effect of the C.P. Crane generating station on zooplankton of the area is a displacement of an original freshwater community through the pumping of cooling water from Seneca Creek to Saltpeter Creek.

Goodyear Lake Hydroelectric Generating Station redevelopment final construction and cost report. DOE small-scale hydroelectric demonstration program  

SciTech Connect

This project is one of the US Department of Energy's original seven low-head hydroelectric demonstration projects. The demonstration project was initiated by the release of a Program Opportunity Notice (PON) ET-78-N-07-1711 dated November 1, 1978. The purpose for the demonstration is to show the feasibility of small hydroelectric power development projects at a number of existing dam sites across the country. The Goodyear Lake Power Station provided an excellent example of the redevelopment of a discontinued low-head hydroelectric facility. The dam and power station were previously owned by the New York State Electric and Gas Corporation. Prior to F.W.E. Stapenhorst's involvement, it was the Utility's intention to breach the dam and dewater the lake. In order to rehabilitate the power station, title was transferred to F.W.E. Stapenhorst Inc., upon finalization of a Power Agreement (whereby F.W.E. Stapenhorst Inc. would sell the power generated to New York State Electric and Gas Corporation) and issuance of the FERC license. The station, as renovated, is fully automatic and utilizes two Ossberger Cross-Flow type turbines - turbines which, due to their flat efficiency curve, are well suited for small rivers and streams where the flow varies over a wide range. Both technical and financial feasibility of the project were carefully analyzed prior to the commencement of the project. The US Department of Energy awarded a cooperative agreement whereby DOE would share $245,000 of the project costs. The Goodyear Lake Station was the first demonstration project under the auspices of the Department of Energy to achieve power-on-line and to be officially dedicated.

Integrated mild gasification processing at the Homer City Electric Power Generating Station site. Final report, July 1989--June 1993  

SciTech Connect

A new process for the production of commercial grade coke, char, and carbon products has been evaluated by Penelec/NYSEG. The process, developed by Coal Technology Corporation, CTC, utilizes a unique screw reactor to produce a devolatilized char from a wide variety of coals for the production of commercial grade coke for use in blast furnaces, foundries, and other processes requiring high quality coke. This process is called the CTC Mild Gasification Process (MGP). The process economics are significantly enhanced by integrating the new technology into an existing power generating complex. Cost savings are realized by the coke producer, the coke user, and the electric utility company. Site specific economic studies involving the Homer City Generating Station site in Western Pennsylvania, confirmed that an integrated MGP at the Homer City site, using coal fines produced at the Homer City Coal Preparation Plant, would reduce capital and operating costs significantly and would enable the HC Owners to eliminate thermal dryers, obtain low cost fuel in the form of combustible gases and liquids, and obtain lower cost replacement coal on the spot market. A previous report, identified as the Interim Report on the Project, details the technical and economic studies.

Evaluation of C. P. Crane Generating Station thermal discharge effects on the finfish community, summer 1980. Final report  

SciTech Connect

The objective of this study was to verify if patterns of abundance observed during Summer, 1980 reflected response to the thermal discharge of the power plant or if they might be attributed to other factors. Fish were collected by both trawling and gill nets at seven stations. Results indicated that the patterns previously attributed to thermal effects may be better explained by habitat preference.

Phytoplankton studies and nutrient concentrations in the vicinity of the C. P. Crane Generating Station. Final report Jul 79 to Mar 80  

SciTech Connect

Plant operations at the C.P. Crane Generating Station, Baltimore County, Maryland, appeared to stimulate phytoplankton productivity at plant discharge and in upper Saltpeter Creek, from July 1979 through March 1980. Carbon fixation rates and assimulation ratios were enhanced in whole-water and nanoplankton size fractions for the three upper Saltpeter Creek stations compared to data collected at intake (Seneca Creek). However, few significant alterations in phytoplankton biomass (chlorophyll alpha) resulting plant operations were noted in the vicinity of the C.P. Crane plant. Enhanced productivities were probably a function of ambient water temperatures, Delta Ts observed between intake and the impacted areas and species composition of the phytoplankton. Increases in ammonium and nitrate, possibly plant-induced, were observed during four months. Since no direct indications of plant impact in the lower Gunpowder River were determined, data suggest that effects were limited to the immediate area of the canal discharge.

Field testing of behavioral barriers for fish exclusion at cooling-water intake systems, Central Hudson Gas and Electric Company Roseton Generating Station: Final report  

SciTech Connect

A seasonal field testing program was conducted during 1986 and 1987 to evaluate the effectiveness of behavioral barriers at Central Hudson Gas and Electric Corporations's Roseton Generating Station located in the euryhaline section of the Hudson River. This station was selected as representative of power plants with shoreline riverine/estuarine intake systems. Three commercially available devices (air bubble curtain, pneumatic gun, and underwater strobe light) were tested alone and in combination to determine their effectiveness in reducing impingement. The primary testing method incorporated three or four 6-h impingement collections during each test date, each consisting of two randomly assigned 3-h samples: one was an experimental test with a behavioral device in operation, the other a control test with no device operating. The effectiveness of the devices at excluding fish was determined by comparing impingement data from experimental and control periods. Results of the program do not establish that the deployment of underwater strobe lights, pneumatic guns, an air bubble curtain, or various combinations of the three devices will effectively lower fish impingement at power plants similar in design and location to the Roseton plant. Deterrent effectiveness was found to be species-specific and related to time of day. 51 refs., 67 figs., 72 tabs.

Ecological studies of wood-boring bivalves and fouling organisms in the vicinity of the Oyster Creek Nuclear Generating Station. Final report, September 1976-December 1982  

SciTech Connect

The species composition, distribution, and population dynamics of wood-boring bivalves were studied using wood test panels at 20 stations in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Physiological tolerances of three teredinid species were investigated in the laboratory and correlated with field values of temperature, salinity, siltation, precipitation, and plant operations. The interaction of boring and fouling organisms was examined. There is a definite correlation between the operation of the power plant and teredinid outbreaks. Increased salinity and water flow as well as temperature are responsible. After 1976, most of the damage in Oyster Creek was done by the introduced subtropical species Teredo bartschi. It can respond faster than native species to environmental change. Although Oyster Creek contributed larvae to neighboring parts of Barnegat Bay, its role as a breeding ground was limited. Some elements of the fouling community may be antagonistic to shipworm growth. Fouling was increased in both biomass and species richness in Oyster Creek when compared with creek controls, but the fouling community in Oyster Creek was less stable than that in other areas. Lower salinity limits for the teredinids were within the salinity range found in Oyster Creek but not within the range found in the control creeks. 71 references, 9 figures, 39 tables.

Navajo Generating Station and Air Visibility Regulations: Alternatives and Impacts  

SciTech Connect

Pursuant to the Clean Air Act, the U.S. Environmental Protection Agency (EPA) announced in 2009 its intent to issue rules for controlling emissions from Navajo Generating Station that could affect visibility at the Grand Canyon and at several other national parks and wilderness areas. The final rule will conform to what EPA determines is the best available retrofit technology (BART) for the control of haze-causing air pollutants, especially nitrogen oxides. While EPA is ultimately responsible for setting Navajo Generating Station's BART standards in its final rule, it will be the U.S. Department of the Interior's responsibility to manage compliance and the related impacts. This study aims to assist both Interior and EPA by providing an objective assessment of issues relating to the power sector.

Nuclear Generating Stations and Transmission Grid Reliability  

SciTech Connect

Nuclear generating stations have historically been susceptible to transmission system voltage excursions. When nuclear plants trip due to voltage excursions, the resulting loss of real and reactive power support can make grid events worse. New standards are being prepared which may help to improve nuclear plant and transmission system reliability. A brief historical perspective is provided. Another reliability issue is the fact that nuclear plants do not provide automatic generation control in response to frequency decay. As 28 new nuclear plants are being considered for connection to an already highly stressed transmission grid, consideration must be given to nuclear plant design features which will enhance, not degrade, transmission system reliability.

NASA Technical Reports Server (NTRS)

A system for displaying at a remote station data generated at a central station and for powering the remote station from the central station is presented. A power signal is generated at the central station and time multiplexed with the data and then transmitted to the remote station. An energy storage device at the remote station is responsive to the transmitted power signal to provide energizing power for the circuits at the remote station during the time interval data is being transmitted to the remote station. Energizing power for the circuits at the remote station is provided by the power signal itself during the time this signal is transmitted. Preferably the energy storage device is a capacitor which is charged by the power signal during the time the power is transmitted and is slightly discharged during the time the data is transmitted to energize the circuits at the remote station.

Next-Generation GPS Station for Hazards Mitigation (Invited)  

NASA Astrophysics Data System (ADS)

Our objective is to better forecast, assess, and mitigate natural hazards, including earthquakes, tsunamis, and extreme storms and flooding through development and implementation of a modular technology for the next-generation in-situ geodetic station to support the flow of information from multiple stations to scientists, mission planners, decision makers, and first responders. The same technology developed under NASA funding can be applied to enhance monitoring of large engineering structures such as bridges, hospitals and other critical infrastructure. Meaningful warnings save lives when issued within 1-2 minutes for destructive earthquakes, several tens of minutes for tsunamis, and up to several hours for extreme storms and flooding, and can be provided by on-site fusion of multiple data types and generation of higher-order data products: GPS/GNSS and accelerometer measurements to estimate point displacements, and GPS/GNSS and meteorological measurements to estimate moisture variability in the free atmosphere. By operating semi-autonomously, each station can then provide low-latency, high-fidelity and compact data products within the constraints of narrow communications bandwidth that often accompanies natural disasters. We have developed a power-efficient, low-cost, plug-in Geodetic Module for fusion of data from in situ sensors including GPS, a strong-motion accelerometer module, and a meteorological sensor package, for deployment at existing continuous GPS stations in southern California; fifteen stations have already been upgraded. The low-cost modular design is scalable to the many existing continuous GPS stations worldwide. New on-the-fly data products are estimated with 1 mm precision and accuracy, including three-dimensional seismogeodetic displacements for earthquake, tsunami and structural monitoring and precipitable water for forecasting extreme weather events such as summer monsoons and atmospheric rivers experienced in California. Unlike more traditional approaches where data are collected and analyzed from a network of stations at a central processing facility, we are embedding these capabilities in the Geodetic Module's processor for in situ analysis and data delivery through TCP/IP to avoid single points of failure during emergencies. We are infusing our technology to several local and state groups, including the San Diego County Office of Emergency Services for earthquake and tsunami early warnings, UC San Diego Health Services for hospital monitoring and early warning, Caltrans for bridge monitoring, and NOAA's Weather Forecasting Offices in San Diego and Los Angeles Counties for forecasting extreme weather events. We describe our overall system and the ongoing efforts at technology infusion.

This paper attempts to promote the understanding of terminology, discusses some of the differences in supply and describes some of the assessment methods associated with the reliability of the offsite power supply. Topics considered include terminology and reliability indices, grid collapse, multiple line outages, loss of switchyard, loss of transformers, and auxiliary bus outage. Minimum requirements for the offsite supply to generating stations must satisfy both economic and safety considerations. Failure mode and effects analysis (FMEA) is discussed. It is concluded that the various requirements of plant loads being supplied and alternative options in the restoration process require that reliability evaluation analyses be tailored to the individual site and load.

Public response to the Diablo Canyon Nuclear Generating Station  

SciTech Connect

The authors examine the nature of the public response to the Diablo Canyon Nuclear Generating Station located in San Luis Obispo, California, from the early 1960s to the present. Four distinct phases of public intervention were discerned, based on change in both plant-related issues and in the nature of the antinuclear constituencies in the region. The level of public concern varied both geographically and temporally and is related to the area's social structure, environmental predispositions, and distribution of plant-related economic benefits. External events, such as the prolonged debate over the risk assessment of the seismic hazard and the Three Mile Island accident were found to be important factors in explaining variation in public concern and political response.

ISSLIVE! Bringing the Space Station to Every Generation  

NASA Technical Reports Server (NTRS)

Just 200 miles above us, the International Space Station (ISS) is orbiting. Each day, the astronauts on board perform a variety of activities from exercise, science experiments, and maintenance. Yet, many on the ground don?t know about these daily activities. ISSLive! - an education project - is working to bridge this knowledge gap with traditional education channels such as schools, but also non-traditional channels with the non-technical everyday public. ISSLive! provides a website that seamlessly integrates planning and telemetry data, video feeds, 3D models, and iOS and android applications. Through the site, users are able to view astronauts? daily schedules, in plain English alongside the original data. As an example, when an astronaut is working with a science experiment, a user will be able to read about the activity and for more detailed activities follow provided links to view more information -- all integrated into the same site. Live telemetry data from a predefined set can also be provided alongside the activities. For users to learn more, 3D models of the external and internal parts of the ISS are available, allowing users to explore the station and even select sensors, such as temperature, and view a real-time chart of the data. Even ground operations are modelled with a 3D mission control center, providing users information on the various flight control disciplines and showing live data that they would be monitoring. Some unique activities are also highlighted, and have dedicated spaces to explore in more detail. Education is the focus of ISSLive!, even from the beginning when university students participated in the development process as part of their master?s projects. Focus groups at a Houston school showed interest in the project, and excitement towards including ISSLive! in their classroom. Through this inclusion, student?s knowledge can be assessed with projects, oral presentations, and other assignments. For the public citizens outside of the traditional education system, ISSLive! provides a single, interactive, and engaging experience to learn about the ISS and its role in space exploration, international collaboration, and science. While traditional students are using ISSLive! in the classroom, their parents, grandparents, and friends are using it at home. ISSLive! truly brings the daily operations of the ISS into the daily lives of the public from every generation.

Goodyear Lake hydroelectric generating station redevelopment. Final operating cost report  

SciTech Connect

The Goodyear Lake how-head hydropower plant resulted from the rehabilitation of an old dam. The project construction costs were $1.722 million, which included a 17% overrun from original cost estimates due chiefly to extraordinary rates of inflation. For the first two years operating costs were $126,500 and $240,100 while revenues were $233,200 and $403,400, respectively. Revenues for year 1 were obtained from sales at 3 cents/kWh and for year 2 at 3.4 cents/kWh. If the rates payable by utilities under PURPA regulations, namely 6 cents/kWh, had been paid the revenues would have nearly doubled. It is concluded that initial cost overruns are not readily recuperable. (LCL)

Main Generator Seal Oil Supply Reliability Improvements at Southern California Edison's San Onofre Nuclear Generating Station  

SciTech Connect

This paper presents the justification for the approach, details and results of the Main Generator Seal Oil System reliability enhancements on the San Onofre Nuclear Generating Station, SONGS. The SONGS, Unit 3 experienced substantial turbine damage in early 2001 after the turbine bearings lubrication oil supply failed. During a loss of off-site power incident, power was lost to the two AC powered turbine lubrication oil pumps due to a breaker failure in the switchgear and the DC powered emergency bearing lubricating oil pump failed to start due to a breaker trip. The SONGS turbine generators coasted down from full speed to a full stop without lubricating oil. This resulted in significant bearing, journal and steam path damage that required a four-month duration repair outage during a time period where electricity was in short supply in the State of California. The generator hydrogen sealing system remained operable during this event, however it was recognized during the event follow up investigation that this system had vulnerabilities to failure similar to the bearing lubrication system. In order to prevent a reoccurrence of this extremely costly event, SONGS has taken actions to modify both of these critical turbine generator systems by adding additional, continuously operating pumps with a new, independent power source and independently routed cables. The main challenge was to integrate the additional equipment into the existing lubrication and seal oil systems. The lubrication Oil System was the first system to be retro-fitted and these results already have been presented. Reference 2. This paper provides the result of the reliability enhancements for the Main Generator Seal Oil System, which concludes the turbine/generator critical oil systems reliability improvements, performed by SONGS. It is worth noting that the design team discovered and corrected a number of other significant operational issues, which had been present from the early days and also learned a great deal of detailed information about this vital system during the project. The SONGS approach and findings are discussed in this paper, as well as a summary of the work performed. This technical paper will be of interest to utilities with a need to improve turbine generator reliability issues. (authors)

DESIGNING AND OPPORTUNITY FUEL WITH BIOMASS AND TIRE-DERIVED FUEL FOR COFIRING AT WILLOW ISLAND GENERATING STATION AND COFIRING SAWDUST WITH COAL AT ALBRIGHT GENERATING STATION  

SciTech Connect

During the period July 1, 2000-March 31, 2004, Allegheny Energy Supply Co., LLC (Allegheny) conducted an extensive demonstration of woody biomass cofiring at its Willow Island and Albright Generating Stations. This demonstration, cofunded by USDOE and Allegheny, and supported by the Biomass Interest Group (BIG) of EPRI, evaluated the impacts of sawdust cofiring in both cyclone boilers and tangentially-fired pulverized coal boilers. The cofiring in the cyclone boiler--Willow Island Generating Station Unit No.2--evaluated the impacts of sawdust alone, and sawdust blended with tire-derived fuel. The biomass was blended with the coal on its way to the combustion system. The cofiring in the pulverized coal boiler--Albright Generating Station--evaluated the impact of cofiring on emissions of oxides of nitrogen (NO{sub x}) when the sawdust was injected separately into the furnace. The demonstration of woody biomass cofiring involved design, construction, and testing at each site. The results addressed impacts associated with operational issues--capacity, efficiency, and operability--as well as formation and control of airborne emissions such as NO{sub x}, sulfur dioxide (SO{sub 2}2), opacity, and mercury. The results of this extensive program are detailed in this report.

Life assessment of large power cables in fossil fuel generating stations  

SciTech Connect

As part of fossil generating station upgrades, the major components of the electrical station service system (i.e., the large power cables for the generator leads, transformer secondaries, and motor feeders) are evaluated for increased capacity, continued reliability, and additional service life. This paper discusses the cable aging mechanisms for fossil-power stations, including thermal aging of insulation, insulation voltage stress, corrosion of lead in lead-sheathed cables, long-term water absorption by insulation, and water treeing of insulation. Also presented are approaches to analyzing these aging mechanisms to assess the life of the cable. Cable design and installations that merit particular attention during a life assessment study include feeders using multiple conductors per phase, unjacketed lead-sheathed cable, unshielded 5 kV power cable installed in conduit, cables using butyl and SBR insulation systems, cable bus systems, and cross-linked-polyethylene (XLPE)-insulated cables in underground installations.

Improved windpower generating system. Final report  

SciTech Connect

The following report describes a research and development program to investigate an improved windpower generating system. The improved rotor design combines the high starting torque of multi-blade horizontal-axis rotors with the high efficiency of ''propeller'' type rotors. The resulting ''compound'' rotor is believed to have significant advantages over more conventional rotors, particularly for pumping operations. The R and D program involved both analysis and testing. Computer-based rotor analysis programs were modified to accommodate the aerodynamic characteristics of the compounds rotor. The performance of single-surface airfoil sections were investigated in a series of wind tunnel tests. Based on the analytic and airfoil test results, a compound rotor with a diameter of 20.5 ft was designed and tested. The test data verified the calculated performance of the compound rotor and provided the basis for application studies. 10 refs., 50 figs.

Insulation co-ordination aspects for power stations with generator circuit-breakers  

SciTech Connect

The generator circuit-breaker (gen. c.b.) located between the generator and the step-up transformer, is now being applied world-wide. It has become a recognized electrical component of power stations which is largely due to economical advantages and increased power station availability. Technical protection considerations for power stations have always been the reason for discussion and the object of improvement. With the use of a gen. c.b., some points of view need to be considered anew. Not only the protection system in case of fault conditions will be influenced, but also the insulation co-ordination philosophy. Below the results of some calculations concerning expected overvoltages are presented. These calculations are based on a transformer rated 264/15.5kV, 220 MVA. But the results are transferable to other power plants. Some measurements carried out on a transformer of the same rating complement the calculations. The findings may contribute to an improvement in insulation co-ordination and protection of the electrical system generator--step-up transformer.

Next-Generation Linear Collider Final Focus System Stability Tolerances  

SciTech Connect

The design of final focus systems for the next generation of linear colliders has evolved largely from the experience gained with the design and operation of the Stanford Linear Collider (SLC) and with the design of the Final Focus Test Beam (FFTB). We will compare the tolerances for two typical designs for a next-generation linear collider final focus system. The chromaticity generated by strong focusing systems, like the final quadrupole doublet before the interaction point of a linear collider, can be canceled by the introduction of sextupoles in a dispersive region. These sextupoles must be inserted in pairs separated by a -I transformation (Chromatic Correction Section) in order to cancel the strong geometric aberrations generated by sextupoles. Designs proposed for both the JLC or NLC final focus systems have two separate chromatic correction sections, one for each transverse plane separated by a ''{beta}-exchanger'' to manipulate the {beta}-function between the two CCS. The introduction of sextupoles and bending magnets gives rise to higher order aberrations (long sextupole and chrome-geometries) and radiation induced aberrations (chromaticity unbalance and ''Oide effect'') and one must optimize the lattice accordingly.

Surface definition and grid generation about an Assured Crew Return Vehicle (ACRV) for Space Station Freedom  

NASA Technical Reports Server (NTRS)

The surface definition and grid generation about an Assured Crew Return Vehicle (ACRV) for the Space Station Freedom are described. The purpose of the surface definition and grid generation is to provide the necessary geometry information for CFD calculations about the vehicle. There are two salient features in this description. The first is that the numerical model representing the ACRV configuration is obtained from the measurement of an existing wind tunnel model. The method for smoothing the measured data and obtaining the numerical model is described. The second feature is the description of the algebraic grid generation method and software to compute volume grids about the ACRV. The methods and software allow rapid computation of volume grids for a wide range of flow conditions.

Next-Generation Real-Time Geodetic Station Sensor Web for Natural Hazards Research and Applications  

NASA Astrophysics Data System (ADS)

We report on a NASA AIST project focused on better forecasting, assessing, and mitigating natural hazards, including earthquakes, tsunamis, and extreme storms and flooding through development and implementation of a modular technology for the next-generation in-situ geodetic station, and a Geodetic Sensor Web to support the flow of information from multiple stations to scientists, mission planners, decision makers, and first responders. Meaningful warnings save lives when issued within 1-2 minutes for destructive earthquakes, several tens of minutes for tsunamis, and up to several hours for extreme storms and flooding, and can be provided by on-site fusion of multiple data types and generation of higher-order data products: GPS and accelerometer measurements to estimate point displacements, and GPS and meteorological measurements to estimate moisture variability in the free atmosphere. By operating semi-autonomously, each station can provide low-latency, high-fidelity and compact data products within the constraints of narrow communications bandwidth that often accompanies natural disasters. The project encompasses the following tasks, including hardware and software components: (1) Development of a power-efficient, low-cost, plug-in Geodetic Module for fusion of data from in situ sensors including GPS, a MEMS accelerometer package, and a MEMS meteorological sensor package, for deployment at 26 existing continuous GPS stations in southern California. The low-cost modular design is scalable to the many existing continuous GPS stations worldwide. (2) Estimation of new on-the-fly data products with 1 mm precision and accuracy, including three-dimensional broadband displacements and precipitable water, by new software embedded in the Geodetic Module's processor, rather than at a central processing facility. (3) Development of a Geodetic Sensor Web to allow the semi-autonomous sensors to transmit and receive information in real time by means of redundant sensor proxy servers and message broker networks to allow for robust sensor control, flow of data, data products, models and alarms, and to avoid single points of failure during emergencies. The team from SIO and JPL is working with users at the two National Weather Service Weather Forecast Offices in southern California (San Diego and Los Angeles/Oxnard) and NOAA's Earth System Research Laboratory in Boulder to provide tropospheric signal delays and precipitable water vapor estimates for forecasting severe storms and flooding. Broadband displacements for earthquake and tsunami early warning and rapid response are being made available to users in the geophysics community through the Southern California Earthquake Data Center at Caltech.

Station-generated impulse noise and its effects on a T1 carrier signal  

NASA Astrophysics Data System (ADS)

Studies dating back to 1963 emphasize the importance of considering the effects of impulse noise coupled by near end crosstalk (NEXT) as a predominant source of digital transmission error in T1 systems. Relays and switches, rectifier power supplies, ac power wiring, lines carrying test tons, and ringing generators in central offices and remote terminals have all been implicated as impulse noise sources. This study demonstrates that station-generated impulse noise can also be a problem. For instance, when the ringing signal is interrupted on a voice pair in the same cable, the disturbances can be at least 20 dB stronger than intersystem NEXT. While such strong impulses are infrequent, they may be of concern as the DS1 service to customer premises continues to expand. A simple, parallel R-L filter placed in series with a standard telephone set effectively reduce errors in the transmitted data.

Next-Generation Geodetic Station for Natural Hazards Research and Applications  

NASA Astrophysics Data System (ADS)

The last few years have seen an apparent increase in natural disasters worldwide and certainly an increase in disaster-related loss of life and property due to earthquakes, tsunamis, severe storms, and flooding. The latest example is the March 11, 2011 Mw 9.0 Tohoku-oki earthquake and ensuing tsunami and nuclear meltdown, whose devastating humanitarian and socio-economic effects still ripple throughout Japan and the world. Enhanced in situ geodetic monitoring has been shown to be a critical element in mitigating the effects of these types of natural disasters. For example, it took Japanese authorities relying solely on seismic instruments about 20 minutes to determine that a great earthquake had occurred on March 11. Initial estimates by the Japan Meteorological Agency were of a magnitude 6.8 earthquake after 3 minutes, and a magnitude 7.9 after 10-20 minutes. Using the existing real-time high-rate GPS network in Japan (GEONET) in a simulated real-time mode, we demonstrate that it would have taken only 2-3 minutes to determine that the magnitude was 9.0. Early detection of this great earthquake was of the essence, since the first tsunami waves hit the coastline after only 30 minutes. We describe the components of a next-generation in situ geodetic observatory, one of whose primary applications is to forecast, assess, and mitigate these types of natural hazards as part of an information system for scientists, mission planners, decision makers, and first responders. To provide meaningful early warnings for earthquakes (up to several minutes in advance), for tsunamis (several tens of minutes), and for major storms and flooding (up to 24 hours), future geodetic observatories will require continuous displacement and precipitable water estimates, with mm-level precision and accuracy. To achieve this in an efficient manner will require on-site fusion of multiple data types and generation of higher-order data products: Global Navigation Satellite Systems (GNSS) and accelerometer measurements to estimate point displacements, and GNSS and meteorological measurements to estimate precipitable water. By allowing autonomous, low-latency, and compact data products, we anticipate narrow communications bandwidths that often accompany natural disasters, make possible more efficient data analysis, and provide a modular design that can be used to efficiently upgrade the thousands of existing geodetic stations. By integrating individual stations into a real-time geodetic sensor web, in which individual sensors/stations share and update their information with multiple regional processing nodes, the cumulative fidelity of the Earth science products they produce is further enhanced and single points of failure at central processing facilities are eliminated. Next-generation geodetic stations can also supply real-time calibration information to several NASA space missions, e.g., the NPP mission as part of a demonstration of the next-generation weather satellite and the DESDynI mission, and contribute to NASA's Space Geodesy Project (SGP) which is developing the next generation of collocated space geodetic fiducial stations.

Development of an HTS hydroelectric power generator for the hirschaid power station  

NASA Astrophysics Data System (ADS)

This paper describes the development and manufacture of a 1.7MW, 5.25kV, 28pole, 214rpm hydroelectric power generator consisting of superconducting HTS field coils and a conventional stator. The generator is to be installed at a hydro power station in Hirschaid, Germany and is intended to be a technology demonstrator for the practical application of superconducting technology for sustainable and renewable power generation. The generator is intended to replace and uprate an existing conventional generator and will be connected directly to the German grid. The HTS field winding uses Bi-2223 tape conductor cooled to about 30K using high pressure helium gas which is transferred from static cryocoolers to the rotor via a bespoke rotating coupling. The coils are insulated with multi-layer insulation and positioned over laminated iron rotor poles which are at room temperature. The rotor is enclosed within a vacuum chamber and the complete assembly rotates at 214rpm. The challenges have been significant but have allowed Converteam to develop key technology building blocks which can be applied to future HTS related projects. The design challenges, electromagnetic, mechanical and thermal tests and results are presented and discussed together with applied solutions.

Devon station repowering study: Phase 2, Conceptual design of a coal gasification facility: Final report  

SciTech Connect

The 1985 conceptual design and economic analysis of a coal gasification facility producing medium-Btu fuel gas from a Pittsburgh bituminous coal is described in this report. The gasification facility is sited at Connecticut Light and Power Company's Devon Generating Station, Milford, Connecticut. The report was prepared by Lummus Crest, Inc., United Engineers and Constructors, and Northeast Utilities Service Company. Northeast Utilities Service Company and the Electric Power Research Institute co-sponsored the study. The facility design incorporates the proprietary Shell Coal Gasification Process. This process uses a pressurized, high temperature, entrained flow gasification reactor to perform the initial conversion of coal to gas. Dry pulverized coal, oxygen, and a small quantity of steam is fed into the process to produce a medium-Btu gas with a higher heating value of 301.0 Btu/SCF. The plant consumes 5688 tons of coal per day to produce 5083 MM Btu/hr of medium-Btu gas. The synthetic gas is supplied to a combined cycle plant adjacent to the proposed facility. Minimal integration of the gasification and combined cycle systems is included in the plant design. A description of the site and plant facilities, including overall material and energy balances, block flow diagrams, and site arrangement drawings, are presented. A description of the major systems, including an equipment summary, are also provided. An overall capital cost estimate and project execution schedule were prepared. An engineering and economic analysis of the impact of adding the coal gasification facility to the repowering project is presented. This analysis, prepared by Northeast Utilities Service Company, compares the gasified coal combined cycle plant with two options, a pulverized coal steam plant and the repowered plant without the gasification facility. 13 figs., 23 tabs.

International Space Station United States Orbital Segment Oxygen Generation System On-Orbit Operational Experience  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) United States Orbital Segment (USOS) Oxygen Generation System (OGS) was originally intended to be installed in ISS Node 3. The OGS rack delivery was accelerated, and it was launched to ISS in July of 2006 and installed in the US Laboratory Module. Various modification kits were installed to provide its interfaces, and the OGS was first activated in July of 2007 for 15 hours, In October of 2007 it was again activated for 76 hours with varied production rates and day/night cycling. Operational time in each instance was limited by the quantity of feedwater in a Payload Water Reservoir (PWR) bag. Feedwater will be provided by PWR bag until the USOS Water Recovery System (WRS) is delivered to SS in fall of 2008. This paper will discuss operating experience and characteristics of the OGS, as well as operational issues and their resolution.

A Second-Generation Volatile Organic Analyzer for the International Space Station  

NASA Technical Reports Server (NTRS)

Early in the development of the Crew Health Care System (CHECS) for the International Space Station (ISS), it was recognized that detection of target volatile organic compounds would be a key component of the air monitoring strategy. Experiences during the NASA/Mir program supported the decision to include a real-time volatile organic analyzer (VOA) aboard ISS to help assess the impact of air quality events on crew health and determine the effectiveness of decontamination efforts. Toward this end, a joint development by the Toxicology Laboratory at Johnson Space Center and Graseby Dynamics produced a VOA that has been delivered and is ready for the first 5 years of ISS operation. The first-generation VOA selection criteria included minimizing size, weight, and power consumption while maintaining analytical performance. Measuring available technologies against these criteria, a VOA system based upon gas chromatography/ion mobility spectrometry (GC/IMS) was selected in the mid-90's. However, as NASA looks forward to later-stage ISS operations and to new frontiers such as human exploration of Mars, the ISS VOA (weighing 43 kg and consuming 160 watts) must be replaced by a smaller, less resource-intensive device. This paper will present a possible second-gene ration VOA based upon the same technology as the first-generation unit. Utilizing GC/IMS technology again will permit the instrumental data and experience gained during the initial phase of ISS to be applied to later ISS phases and advanced spacecraft missions. During the past 3 years, efforts to reduce the size of ion mobility spectrometers have been pursued by Graseby Dynamics, the manufacturer of the first-generation VOA. The concept of operation, expected analytical performance, and estimated size of a fully functional second-generation VOA based upon GC/mini-IMS technology will be presented. Furthermore, results of initial laboratory evaluations will be shown.

Oconee Nuclear Power Station Main Steam Line Break Analysis for Steam Generator Tube Stress Evaluation  

SciTech Connect

For certain steam line break (SLB) analyses, the RETRAN-3D Oconee model predicts water carryout through the break. The amount of liquid carried from the system is dependent on the assumed break size, feedwater boundary conditions, and initial conditions. Although liquid carryout is potentially realistic during this scenario, there are no plant or test facility data on which to validate the amount of water carryout.Because the steam generator tube stress evaluation is a safety related analysis, a conservative approach is required. Overcooling effects for an SLB transient are maximized by retaining as much steam generator liquid as possible to remove energy from the reactor coolant system. Because water carryout is nonconservative, and due to the lack of data, the analysis is performed assuming no liquid is carried from the break. This boundary condition is difficult to impose on a RETRAN-3D analysis since the amount of liquid entrained in the break flow is determined by internal code models, which the analyst cannot control directly.This paper presents the methodology used to eliminate water carryout for these types of calculations. The methodology consists of a combination of special RETRAN-3D code modifications and model input changes.In the second part of the paper, the results of an SLB analysis for the Oconee Nuclear Station employing the above methodology are presented. These analyses are done to compute the temperature differences between the steam generator tubes and the shell of the once-through steam generator. The temperature of the thin tubes decreases much faster than the temperature of the shell during an overcooling transient such as an SLB, resulting in tensile stresses that might lead to tube failures.A number of break sizes were analyzed starting with a double-ended main SLB down to a small break of 0.0372 m{sup 2} (0.4 ft{sup 2}). The sensitivity of the tube tensile stress to the assumed break size is presented.

A new generation of small satellite communication earth stations suited to transportable, emergency and disaster response applications  

NASA Astrophysics Data System (ADS)

The requirements, design, implementation, testing, and operation in Canada of a new generation of small satellite communication earth stations are presented. The stations, suited to transportable, emergency, and disaster response applications, operate via Telesat's commercial Anik satellites at 6/4 GHz, and are designed to be capable of global operation via other 6/4 GHz satellites. Telesat has instituted the use of satellites allowing communication to remote communities, and in 1975, 12 small air-transportable earth stations were implemented for temporary and emergency communications. In May 1978, a 3.7 m transportable earth station was set up to demonstrate satellite-terrestrial communications during a simulated oil spill. This experience led to the conclusion that transportable satellite stations were needed. Station test results show that error rates in telephone signalling processing are as low as 10 to the -2nd, acceptable performance of voice-activated delta-codec 40 kbps PSK-modulated signal is experienced at 55 dB-Hz, and the G/T of such a station is at least 19 dB/K.

Development of the Second Generation International Space Station (ISS) Total Organic Carbon Analyzer (TOCA)  

NASA Technical Reports Server (NTRS)

The second generation International Space Station (ISS) Total Organic Carbon Analyzer s (TOCA) function is to monitor concentrations of Total Organic Carbon (TOC) in ISS water samples. TOC is one measurement that provides a general indication of overall water quality by indicating the potential presence of hazardous chemicals. The data generated from the TOCA is used as a hazard control to assess the quality of the reclaimed and stored water supplies on-orbit and their suitability for crew consumption. This paper details the unique ISS Program requirements, the design of the ISS TOCA, and a brief description of the on-orbit concept-of-operations. The TOCA schematic will be discussed in detail along with specific information regarding key components. The ISS TOCA was designed as a non-toxic TOC analyzer that could be deployed in a flight ready package. This basic concept was developed through laboratory component level testing, two moderate fidelity integrated system breadboard prototypes, a flight-like full scale prototype, as well as lessons learned from the inadequacies of the first unit. The result: a new TOCA unit that is robust in design and includes special considerations to microgravity and the on-orbit ISS environment. TOCA meets the accuracy needs of the ISS Program with a 1,000 to 25,000 g/L range, accurate to within +/-25%.

MELCOR Analysis of Steam Generator Tube Creep Rupture in Station Blackout Severe Accident  

SciTech Connect

A pressurized water reactor steam generator tube rupture (SGTR) is of concern because it represents a bypass of the containment for radioactive materials to the environment. In a station blackout accident, tube integrity could be threatened by creep rupture, particularly if cracks are present in the tube walls. Methods are developed herein to improve assessment capabilities for SGTR by using the severe-accident code MELCOR. Best-estimate assumptions based on recent research and computational fluid dynamics calculations are applied in the MELCOR analysis to simulate two-dimensional natural circulation and to determine the relative creep-rupture timing in the reactor coolant pressure boundary components. A new method is developed to estimate the steam generator (SG) hottest tube wall temperature and the tube critical crack size for the SG tubes to fail first. The critical crack size for SG tubes to fail first is estimated to be 20% of the wall thickness larger than by a previous analysis. Sensitivity studies show that the failure sequence would change if some assumptions are modified. In particular, the uncertainty in the countercurrent flow limit model could reverse the failure sequence of the SG tubes and surge line.

Final Report for Intravenous Fluid Generation (IVGEN) Spaceflight Experiment  

NASA Technical Reports Server (NTRS)

NASA designed and operated the Intravenous Fluid Generation (IVGEN) experiment onboard the International Space Station (ISS), Increment 23/24, during May 2010. This hardware was a demonstration experiment to generate intravenous (IV) fluid from ISS Water Processing Assembly (WPA) potable water using a water purification technique and pharmaceutical mixing system. The IVGEN experiment utilizes a deionizing resin bed to remove contaminants from feedstock water to a purity level that meets the standards of the United States Pharmacopeia (USP), the governing body for pharmaceuticals in the United States. The water was then introduced into an IV bag where the fluid was mixed with USP-grade crystalline salt to produce USP normal saline (NS). Inline conductivity sensors quantified the feedstock water quality, output water purity, and NS mixing uniformity. Six 1.5-L bags of purified water were produced. Two of these bags were mixed with sodium chloride to make 0.9 percent NS solution. These two bags were returned to Earth to test for compliance with USP requirements. On-orbit results indicated that all of the experimental success criteria were met with the exception of the salt concentration. Problems with a large air bubble in the first bag of purified water resulted in a slightly concentrated saline solution of 117 percent of the target value of 0.9 g/L. The second bag had an inadequate amount of salt premeasured into the mixing bag resulting in a slightly deficient salt concentration of 93.8 percent of the target value. The USP permits a range from 95 to 105 percent of the target value. The testing plans for improvements for an operational system are also presented.

Two economic papers: I. Monopsony power and the supply of power from small generating stations; II. A preliminary economic analysis of the value of contributions by small dams to system generation reliability  

SciTech Connect

A small, private developer of an electric-generation station without an immediate demand for his output must sell his power through the transmission and distribution system of the electric utility within whose service area the developer's station is located. This effective control of the market (through the ownership of the local grid) provides the utility with monopsony buying power over potential suppliers of electric generation. What this power implies in the small-station-generator market, in the retail market, and to the development of the small power production is examined in Economic Paper I. The analysis shows the associated deadweight loss in that market and the final product attributable to the monopsony power. In Economic Paper II, a framework is established that determines the value of capital for capacity when that capacity does not necessarily produce electricity, but is in place to assure system reliability. The Energy Law Institute believes it is reasonable to view small dams, even with highly varying outputs, as positively contributing to system reliability and that the supplier should be remunerated.

Structural integrity analysis of the degraded drywell containment at the Oyster Creek Nuclear generating station.  

SciTech Connect

This study examines the effects of the degradation experienced in the steel drywell containment at the Oyster Creek Nuclear Generating Station. Specifically, the structural integrity of the containment shell is examined in terms of the stress limits using the ASME Boiler and Pressure Vessel (B&PV) Code, Section III, Division I, Subsection NE, and examined in terms of buckling (stability) using the ASME B&PV Code Case N-284. Degradation of the steel containment shell (drywell) at Oyster Creek was first observed during an outage in the mid-1980s. Subsequent inspections discovered reductions in the shell thickness due to corrosion throughout the containment. Specifically, significant corrosion occurred in the sandbed region of the lower sphere. Since the presence of the wet sand provided an environment which supported corrosion, a series of analyses were conducted by GE Nuclear Energy in the early 1990s. These analyses examined the effects of the degradation on the structural integrity. The current study adopts many of the same assumptions and data used in the previous GE study. However, the additional computational recourses available today enable the construction of a larger and more sophisticated structural model.

HT to HTO conversion and field experiments near Darlington Nuclear Power Generating Station (DNPGS) site.  

PubMed

The Canadian input parameters related to tritiated hydrogen gas (HT) used in tritium dose models are currently based on experiments performed at the Chalk River Laboratories (CRL) site in 1986, 1987 and 1994. There is uncertainty in how well other sites experiencing atmospheric HT releases are represented by these data. In order to address this uncertainty, HT to HTO conversion factors were evaluated at different locations near the Darlington Nuclear Power Generating Station (DNPGS) site using various experimental approaches. These were D2 gas exposure chamber experiments, atmospheric tritium measurements, and HTO and OBT measurements in vegetation and soil. In addition to these field experiments, chamber experiments were conducted using HT gas on field soil samples. The suggested Canadian input parameters for atmospheric tritium releases estimate the total fraction of HT oxidized in air and in soil, at the site, to be up to a maximum of 2.4%. Based on the more limited data obtained near DNPGS in early spring, this fraction would likely be closer to 0.5%. The result suggests that current parameters provide a conservative estimate for the DNPGS site. PMID:24565644

IEEE standard for design qualification of safety systems equipment used in nuclear power generating stations  

SciTech Connect

This standard is written to serve as a general standard for qualification of all types of safety systems equipment, mechanical and instrumentation as well as electrical. It also establishes principles and procedures to be followed in preparing specific safety systems equipment standards. Guidance for qualifying specific safety systems equipment may be found in various specific equipment qualification standards that are now available or are being prepared. It is required that safety systems equipment in nuclear power generating stations meet or exceed its performance requirements throughout its installed life. This is accomplished by a disciplined program of design qualification and quality assurance of design, production, installation, maintenance and surveillance. This standard is for the design qualification section of the program only. Design qualification is intended to demonstrate the capability of the equipment design to perform its safety function(s) over the expected range of normal, abnormal, design basis event, post design basis event, and in-service test conditions. Inherent to design qualification is the requirement for demonstration, within limitations afforded by established technical state-of-the-art, that in-service aging throughout the qualified life established for the equipment will not degrade safety systems equipment from its original design condition to the point where it cannot perform its required safety function(s), upon demand. The above requirement reflects the primary role of design qualification to provide reasonable assurance that design- and age-related common failure modes will not occur during performance of safety function(s) under postulated service conditions.

Navajo Generating Station and Clean-Energy Alternatives: Options for Renewables  

SciTech Connect

In January 2012, the National Renewable Energy Laboratory delivered to the Department of the Interior the first part of a study on Navajo Generating Station (Navajo GS) and the likely impacts of BART compliance options. That document establishes a comprehensive baseline for the analysis of clean energy alternatives, and their ability to achieve benefits similar to those that Navajo GS currently provides. This analysis is a supplement to NREL's January 2012 study. It provides a high level examination of several clean energy alternatives, based on the previous analysis. Each has particular characteristics affecting its relevance as an alternative to Navajo GS. It is assumed that the development of any alternative resource (or portfolio of resources) to replace all or a portion of Navajo GS would occur at the end of a staged transition plan designed to reduce economic disruption. We assume that replacing the federal government's 24.3% share of Navajo GS would be a cooperative responsibility of both the U.S. Bureau of Reclamation (USBR) and the Central Arizona Water Conservation District (CAWCD).

A consortium (Los Alamos, Sandia, OR, Livermore) have been collaborating under the GONII project to generate a synthetic seismic data base. Two deliverables were a common code that would run on the various site machines, and the use of these codes to generate parts of the final data base. The data base consists of a large number of shots applied to two geographic models developed by another part of GONII, the salt model and the overthrust model,s which were supplied as large files containing propagation velocity on a 3-D grid. Los Alamos was supplied with the source code of a seismic propagation code written by the French Petroleum Institute. A decision was made to port a subset of the code to Fortran on a node. Part of this contract was spent verifying/debugging the Fortran on a node code; a port of the code was made to run on the Cray. A total of 846 shots were run on the CM5. It was found that files on the SDA are not safe from corruption and the model velocity file may change.

Intake-to-delivered-energy ratios for central station and distributed electricity generation in California  

NASA Astrophysics Data System (ADS)

In previous work, we showed that the intake fraction (iF) for nonreactive primary air pollutants was 20 times higher in central tendency for small-scale, urban-sited distributed electricity generation (DG) sources than for large-scale, central station (CS) power plants in California [Heath, G.A., Granvold, P.W., Hoats, A.S., Nazaroff, W.W., 2006. Intake fraction assessment of the air pollutant exposure implications of a shift toward distributed electricity generation. Atmospheric Environment 40, 7164-7177]. The present paper builds on that study, exploring pollutant- and technology-specific aspects of population inhalation exposure from electricity generation. We compare California's existing CS-based system to one that is more reliant on DG units sited in urban areas. We use Gaussian plume modeling and a GIS-based exposure analysis to assess 25 existing CSs and 11 DG sources hypothetically located in the downtowns of California's most populous cities. We consider population intake of three pollutantsPM 2.5, NO x and formaldehydedirectly emitted by five DG technologiesnatural gas (NG)-fired turbines, NG internal combustion engines (ICE), NG microturbines, diesel ICEs, and fuel cells with on-site NG reformers. We also consider intake of these pollutants from existing CS facilities, most of which use large NG turbines, as well as from hypothetical facilities located at these same sites but meeting California's best-available control technology standards. After systematically exploring the sensitivity of iF to pollutant decay rate, the iFs for each of the three pollutants for all DG and CS cases are estimated. To efficiently compare the pollutant- and technology-specific exposure potential on an appropriate common basis, a new metric is introduced and evaluated: the intake-to-delivered-energy ratio (IDER). The IDER expresses the mass of pollutant inhaled by an exposed population owing to emissions from an electricity generation unit per quantity of electric energy delivered to the place of use. We find that the central tendency of IDER is much greater for almost every DG technology evaluated than for existing CS facilities in California.

Verification and Validation of the GNSS Stations at the Prototype Core Site for NASA's Next Generation Space Geodesy Network  

NASA Astrophysics Data System (ADS)

Two operational GNSS stations, GODN and GODS, were established within 100 m of each other at the prototype core site of NASA's next generation Space Geodesy Network. The planned network will co-locate each of the four space geodetic techniques, GNSS, SLR, VLBI, and DORIS, with the goal of meeting modern requirements for the International Terrestrial Reference Frame. This prototype site is located at NASA's Geophysical and Astronomical Observatory at the Goddard Space Flight Center. The two GNSS stations at the prototype site have been producing tracking data from the GPS, GLONASS, and Galileo constellations since January 17, 2012. We present results from the verification and validation of these two stations, focusing in particular on GPS-based positioning of these two sites to monitor their relative baseline vector. We compare baseline recovery from independent precise point positioning of each station to a network-based approach. We also show the impact on the baseline as well as station repeatability from various improvements to our processing approach, namely the application of empirical antenna calibrations, elevation-dependent weighting, and site-specific troposphere modeling. Together, these approaches have resulted in a factor of two improvement in the precision of the baseline length. The standard deviation of the baseline vector, when using independent precise positioning of each station, is 0.5, 0.4, 1.6, and 0.4 mm in the east, north, up, and length components. The difference between the GPS-based baseline length and that from an independent local tie survey is < 1 mm.

Remedial investigation of contaminant mobility at Naval Weapons Station, Concord, California. Final report  

SciTech Connect

A remedial investigation was conducted at Naval Weapons Station, Concord, California, to determine the nature and extent of of wetland and terrestrial environments. The evaluation considered major pathways of contaminant migration including soil, water, air and biota. Major testing was conducted on soil and the biological components of the pathways. Chemical analysis of soil samples indicated substantial elevation in arsenic, cadmium, lead, selenium, zinc and copper in certain contaminated areas. Field-conducted clam bioassays showed a moderate potential for lead, cadmium, and zinc to bioaccumulate in clams placed in surface waters of a limited number of sampling sites. Plant and earthworm bioassays indicated substantial movement of arsenic, cadmium, lead, selenium, zinc and copper into plants and soil-dwelling organisms in contaminated areas. A definite threat of these contaminants to impact wildlife, especially the endangered species that inhabit the contaminated sites, was strongly suggested by the toxicological effects of these metals on birds and mammals. A hydrological evaluation indicated substantial movement of hazardous substances into surface waters during storm events and high tides. A comprehensive evaluation of natural resources indicated that the wetland areas have moderate to high functional values for wildlife habitat, food chain support, flood storage, shoreline anchorage, sediment trapping, nutrient retention and passive recreation and heritage.

Life Science on the International Space Station Using the Next Generation of Cargo Vehicles  

NASA Technical Reports Server (NTRS)

With the retirement of the Space Shuttle and the transition of the International Space Station (ISS) from assembly to full laboratory capabilities, the opportunity to perform life science research in space has increased dramatically, while the operational considerations associated with transportation of the experiments has changed dramatically. US researchers have allocations on the European Automated Transfer Vehicle (ATV) and Japanese H-II Transfer Vehicle (HTV). In addition, the International Space Station (ISS) Cargo Resupply Services (CRS) contract will provide consumables and payloads to and from the ISS via the unmanned SpaceX (offers launch and return capabilities) and Orbital (offers only launch capabilities) resupply vehicles. Early requirements drove the capabilities of the vehicle providers; however, many other engineering considerations affect the actual design and operations plans. To better enable the use of the International Space Station as a National Laboratory, ground and on-orbit facility development can augment the vehicle capabilities to better support needs for cell biology, animal research, and conditioned sample return. NASA Life scientists with experience launching research on the space shuttle can find the trades between the capabilities of the many different vehicles to be confusing. In this presentation we will summarize vehicle and associated ground processing capabilities as well as key concepts of operations for different types of life sciences research being launched in the cargo vehicles. We will provide the latest status of vehicle capabilities and support hardware and facilities development being made to enable the broadest implementation of life sciences research on the ISS.

Demonstration of rapid and sensitive module leak certification for space station freedom. Final report  

SciTech Connect

A leak detection and quantification demonstration using perflurocarbon tracer (PFT) technology was successfully performed at the NASA Marshall Space Flight Center on January 25, 1991. The real-time Dual Trap Analyzer (DTA) at one-half hour after the start of the first run gave an estimated leak rate of 0.7 mL/min. This has since been refined to be 1.15 {plus_minus} 0.09 mL/min. The leak rates in the next three runs were determined to be 9.8 {plus_minus} 0.7, {minus}0.4 {plus_minus} 0.3, and 76 {plus_minus} 6 mL/min, respectively. The theory on leak quantification in the steady-state and time-dependent modes for a single zone test facility was developed and applied to the above determinations. The laboratory PFT analysis system gave a limit-of-detection (LOD) of 0.05 fL for ocPDCH. This is the tracer of choice and is about 100-fold better than that for the DTA. Applied to leak certification, the LOD is about 0.00002 mL/s (0.000075 L/h), a 5 order-of-magnitude improvement over the original leak certification specification. Furthermore, this limit can be attained in a measurement period of 3 to 4 hours instead of days, weeks, or months. A new Leak Certification Facility is also proposed to provide for zonal (three zones) determination of leak rates. The appropriate multizone equations, their solutions, and error analysis have already been derived. A new concept of seal-integrity certification has been demonstrated for a variety of controlled leaks in the range of module leak testing. High structural integrity leaks were shown to have a linear dependence of flow on {Delta}p. The rapid determination of leak rates at different pressures is proposed and is to be determined while subjecting the module to other external force-generating parameters such as vibration, torque, solar intensity, etc. 13 refs.

One important objective of NASA has always been to inspire the next generation. NASA and human space flight have a unique ability to capture the imaginations of both students and teachers. The presence of humans onboard the International Space Station (ISS) for more than five years now has provided a foundation for numerous educational activities aimed at capturing the interest and motivating study in the sciences, technology, engineering, and mathematics. Yet even before the Expedition 1 crew arrived at station in November 2000, experiments with student participation were being conducted onboard ISS in support of NASA missions. One of NASA's protein crystal growth experiments had been delivered to station by the shuttle Atlantis during STS-106 in September 2000 and was returned to Earth six weeks later aboard the shuttle Discovery during the STS-92 mission. From very early on it was recognized that students would have a strong interest in the ISS, and that this would provide a unique opportunity for them to get involved and participate in science and engineering projects on ISS.

PWR steam generator tube fretting and fatigue wear: Final report  

SciTech Connect

Experimental work determining the wear rates at an elevated water temperature of 200/degree/C (392/degree/F) for typical pressurized water reactor (PWR) steam generator tubing has been performed. These wear rates have been generated for specific tube/tube support plate interaction characteristics comprised of tube contact force, relative sliding distance and the average time of a single contact event. This information when coupled with predictions of tube/tube support plate interaction characteristics associated with multispan steam generator tube geometries can be used to determine lifetime fretting and fatigue wear rates. This report details the test hardware and techniques employed to obtain the data, and provides insight into tube wear empirical modeling. 51 refs., 154 figs., 14 tabs.

The NGGPP design will attempt to minimize emission of pollutants and consumption of surface water and/or geothermal fluids for cooling service.

Steam generator tube integrity program: Phase II, Final report  

SciTech Connect

The Steam Generator Tube Integrity Program (SGTIP) was a three phase program conducted for the US Nuclear Regulatory Commission (NRC) by Pacific Northwest Laboratory (PNL). The first phase involved burst and collapse testing of typical steam generator tubing with machined defects. The second phase of the SGTIP continued the integrity testing work of Phase I, but tube specimens were degraded by chemical means rather than machining methods. The third phase of the program used a removed-from-service steam generator as a test bed for investigating the reliability and effectiveness of in-service nondestructive eddy-current inspection methods and as a source of service degraded tubes for validating the Phase I and Phase II data on tube integrity. This report describes the results of Phase II of the SGTIP. The object of this effort included burst and collapse testing of chemically defected pressurized water reactor (PWR) steam generator tubing to validate empirical equations of remaining tube integrity developed during Phase I. Three types of defect geometries were investigated: stress corrosion cracking (SCC), uniform thinning and elliptical wastage. In addition, a review of the publicly available leak rate data for steam generator tubes with axial and circumferential SCC and a comparison with an analytical leak rate model is presented. Lastly, nondestructive eddy-current (EC) measurements to determine accuracy of defect depth sizing using conventional and alternate standards is described. To supplement the laboratory EC data and obtain an estimate of EC capability to detect and size SCC, a mini-round robin test utilizing several firms that routinely perform in-service inspections was conducted.

Water-related constraints to the development of geothermal electric generating stations  

SciTech Connect

The water-related constraints, which may be among the most complex and variable of the issues facing commercialization of geothermal energy, are discussed under three headings: (1) water requirements of geothermal power stations, (2) resource characteristics of the most promising hydrothermal areas and regional and local water supply situations, and (3) legal issues confronting potential users of water at geothermal power plants in the states in which the resource areas are located. A total of 25 geothermal resource areas in California, New Mexico, Oregon, Idaho, Utah, Hawaii, and Alaska were studied. Each had a hydrothermal resource temperature in excess of 150/sup 0/C (300/sup 0/F) and an estimated 30-year potential of greater than 100-MW(e) capacity.

Aging of nuclear station diesel generators: Evaluation of operating and expert experience: Phase 1, Study  

SciTech Connect

Pacific Northwest Laboratory evaluated operational and expert experience pertaining to the aging degradation of diesel generators in nuclear service. The research, sponsored by the US Nuclear Regulatory Commission (NRC), identified and characterized the contribution of aging to emergency diesel generator failures. This report, Volume I, reviews diesel-generator experience to identify the systems and components most subject to aging degradation and isolates the major causes of failure that may affect future operational readiness. Evaluations show that as plants age, the percent of aging-related failures increases and failure modes change. A compilation is presented of recommended corrective actions for the failures identified. This study also includes a review of current, relevant industry programs, research, and standards. Volume II reports the results of an industry-wide workshop held on May 28 and 29, 1986 to discuss the technical issues associated with aging of nuclear service emergency diesel generators.

Rankine cycle generators using geothermal fluids. Final progress report  

SciTech Connect

The Rankine Cycle generator was delivered and installed at Gila Hot Springs. Trial runs were made at that time, using Freon 12 as the expansion fluid. These tests showed that the boiler capacity was inadequate. It could not extract enough heat to generate sufficient volumes of Freon gas at the heat and pressure necessary to operate the system at an acceptable level. Increasing and decreasing the flow of hot water had a direct influence on efficiency, but it was not a linear relationship. Added amounts of hot water increased the power very little, but raised the water temperature at the discharge point. This implied that the heat exchange capacity of the boiler was saturated. The reverse was found in the condenser system. There was little increase in pressure of the condenser when we switched from static to run mode. Efficiency was maintained even when the cold water flow was reduced as much as 40%. The tests using Freon 12 resulted in the conclusion that the boiler volume needs to be increased and/or the configuration changed to radically increase its efficiency.

Chemical mixing model of streamflow generation at La Selva Biological Station, Costa Rica  

NASA Astrophysics Data System (ADS)

La Selva Biological Station occupies an area of lowland tropical rainforest in central Costa Rica. Sodium and chloride data were used to quantify the mixing proportions of local runoff and geothermal groundwater at several sites throughout the stream channel system in late April, at the end of the dry season. The fraction of streamflow accounted for by geothermal groundwater varied spatially between 0 and 0.85, indicating a significant contribution to streamflow and to stream solute loads from geothermal groundwater at some sites. In general, higher inputs of geothermal groundwater were found at lower elevations. Over half the flow from one basin (the Salto) was due to geothermal groundwater, suggesting a minimum annual runoff of about 0.7 m of geothermal groundwater from this basin. A plot of {Na}/{Cl} vs. fraction of geothermal groundwater revealed watershed-scale chemical differences between the two major drainage systems (the Sura and the Salto), differences that were not apparent from a traditional two-solute plot of Cl vs. Na concentration. A small (21 mm) storm produced relatively little change in mixing proportions, as most throughfall was apparently retained in the relatively dry soils.

Evaluation of Electrochemically Generated Potable Water Disinfectants for Use on the International Space Station  

NASA Technical Reports Server (NTRS)

Microbial contamination and subsequent growth in spacecraft water systems are constant concerns for missions involving human crews. The current potable water disinfectant is iodine; however, with the end of the Space Shuttle program, there is a need to develop redundant biocide systems which are less dependent on hardware that would need to be launched on a regular basis. Three systems for electrochemical production of potable water disinfectants are being assessed for use on the International Space Station (ISS). Since there is a wide variability in the literature with regards to efficacy in both concentration and exposure time of these disinfectants, there is a need to establish baseline efficacy values. This paper describes a series of tests performed in order to establish optimal concentrations and exposure times for four disinfectants against single and mixed species planktonic and biofilm bacteria and to determine whether these electrochemical disinfection devices are able to produce a sufficient amount of chemical in both concentration and volume to act as a biocide for potable water on ISS.

Microbial contamination and subsequent growth in spacecraft water systems are constant concerns for missions involving human crews. The current potable water disinfectant for the International Space Station (ISS) is iodine; however, with the end of the Space Shuttle Program, there is a need to develop redundant biocide systems that do not require regular up-mass dependencies. Throughout the course of a year, four different electrochemical systems were investigated as a possible biocide for potable water on the ISS. Research has indicated that a wide variability exists with regards to efficacy in both concentration and exposure time of these disinfectants; therefore, baseline efficacy values were established. This paper describes a series of tests performed to establish optimal concentrations and exposure times for four disinfectants against single and mixed species planktonic and biofilm bacteria. Results of the testing determined whether these electrochemical disinfection systems are able to produce a sufficient amount of chemical in both concentration and volume to act as a biocide for potable water on the ISS.

Space Station Power Generation in Support of the Beta Gimbal Anomaly Resolution  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) is the largest and most complex spacecraft ever assembled and operated in orbit. The first U.S. photovoltaic (PV) module, containing two solar arrays, was launched, installed, and activated in early December 2000. After the first week of continuously rotating the U.S. solar arrays, engineering personnel in the ISS Mission Evaluation Room (MER) observed higher than expected electrical currents on the drive motor in one of the Beta Gimbal Assemblies (BGA), the mechanism used to maneuver a U.S. solar array. The magnitude of the motor currents continued to increase over time on both BGA's, creating concerns about the ability of the gimbals to continue pointing the solar arrays towards the sun, a function critical for continued assembly of the ISS. A number of engineering disciplines convened in May 2001 to address this on-orbit hardware anomaly. This paper reviews the ISS electrical power system (EPS) analyses performed to develop viable operational workarounds that would minimize BGA use while maintaining sufficient solar array power to continue assembly of the ISS. Additionally, EPS analyses performed in support of on-orbit BGA troubleshooting exercises is reviewed. EPS capability analyses were performed using SPACE, a computer code developed by NASA Glenn Research Center (GRC) for the ISS program office.

Equating minimalist snowmelt and runoff generation models via validation with a wireless weather station network  

NASA Astrophysics Data System (ADS)

A wireless network of 12 weather stations in the Val Ferret watershed (approximately 21 km2) in the Swiss Alps was used to validate snowmelt models with distributed temperature and radiation data. Using this extensive dataset, an improved yet simplistic degree-day method was compared with a radiation-based method proposed by Hock et al., 1999. The original degree-day approach is a widely used snowmelt model, relating snowmelt directly to air temperature. Numerous hydrological models use this minimalist approach due to its equivalent simplicity. Modifications of this simple method have been proposed in the past which typically incorporate local radiation conditions. However, these modifications generally require more data and/or a finer hydrological grid resolution. Results herein as well as theoretical considerations illustrate that the Hock point or grid-scale method is not always a robust method when combined with spatially explicit rainfall-runoff transformation models. This generalized hydrological application suggests that a simple diurnal cycle of the degree-day melt parameter has the potential to outperform the Hock local radiation-based approach for sub-daily melt simulations. We therefore suggest that the improved degree-day method enables a flexible melt modeling approach, which can be easily adapted into spatially-explicit hydrological models of varying complexity. Furthermore, as this new degree-day method is based upon solely daily temperature extremes, this approach is capable of being adapted for climate change predictions.

Space Station momentum control and reboost requirements for two power generation concepts  

NASA Technical Reports Server (NTRS)

Results are presented of dynamic structural analyses of 75 and 300 kW versions of a solar dynamic (SD) power supply for the Space Station (MSS). The SD is being seriously considered as an alternative to solar panels due to lower areal and mass requirements and higher efficiencies. The functioning principle is to use parabolic concentrators to focus sunlight on a heat engine to boil liquids to drive a turbine. Potential problems are foreseen in terms of the torques which would be experienced by the MSS and the subsequent orbital stability effects. The stability would be altered by changing aerodynmaic drag, altered moment of inertia and angular momentum and the altered center of mass location. The problem is exacerbated by the need to first equip the MSS with solar panels while the SD technology is developed. The analysis shows that the attitude control system will need to be redesigned and resized to accommodate MSS growth with either power system. The effects of the rotating parts of the SD system can be minimized, but further studies are required to determine the effects on the pointing accuracy of the SD, which must be 10 times as precise as that needed by a photovoltaic array.

Denting of nuclear steam generator tubes due to the corrosion of carbon steel support plates is a phenomenon which can compromise the integrity of the primary reactor coolant boundary. The objective of this project was to develop two independent means of determining the characteristics of a dent. One technique is a strain gauge device which directly measures the radius changes of a dented tube, yielding information on the contour of the tube ID and the resulting tube strains. The other technique used a silastic molding agent injected into the dented region to produce a replica of the tubes inner surface which can then be removed from the tube for careful gauging and further study.

These processes include pollutants such as chloride or sulfate and oxidants. The literature thermodynamics of the Fe-H/sub 2/O and Fe-Cl-H/sub 2/O systems were reviewed and summarized in the form of potential-pH diagrams (Pourbaix diagrams) at temperatures from 25 to 300/sup 0/C and of the Fe-O-H system in diagrams of stabilities of compounds as a function of temperature and oxygen potential. Different forms of ferric oxides were considered. The potential action of substances was considered for inhibiting denting reactions as neutralizers, pore-blockers, and buffers.

Messiah College Biodiesel Fuel Generation Project Final Technical Report  

SciTech Connect

Many obvious and significant concerns arise when considering the concept of small-scale biodiesel production. Does the fuel produced meet the stringent requirements set by the commercial biodiesel industry? Is the process safe? How are small-scale producers collecting and transporting waste vegetable oil? How is waste from the biodiesel production process handled by small-scale producers? These concerns and many others were the focus of the research preformed in the Messiah College Biodiesel Fuel Generation project over the last three years. This project was a unique research program in which undergraduate engineering students at Messiah College set out to research the feasibility of small-biodiesel production for application on a campus of approximately 3000 students. This Department of Energy (DOE) funded research program developed out of almost a decade of small-scale biodiesel research and development work performed by students at Messiah College. Over the course of the last three years the research team focused on four key areas related to small-scale biodiesel production: Quality Testing and Assurance, Process and Processor Research, Process and Processor Development, and Community Education. The objectives for the Messiah College Biodiesel Fuel Generation Project included the following: 1. Preparing a laboratory facility for the development and optimization of processors and processes, ASTM quality assurance, and performance testing of biodiesel fuels. 2. Developing scalable processor and process designs suitable for ASTM certifiable small-scale biodiesel production, with the goals of cost reduction and increased quality. 3. Conduct research into biodiesel process improvement and cost optimization using various biodiesel feedstocks and production ingredients.

Coal-fired high performance power generating system. Final report  

SciTech Connect

As a result of the investigations carried out during Phase 1 of the Engineering Development of Coal-Fired High-Performance Power Generation Systems (Combustion 2000), the UTRC-led Combustion 2000 Team is recommending the development of an advanced high performance power generation system (HIPPS) whose high efficiency and minimal pollutant emissions will enable the US to use its abundant coal resources to satisfy current and future demand for electric power. The high efficiency of the power plant, which is the key to minimizing the environmental impact of coal, can only be achieved using a modern gas turbine system. Minimization of emissions can be achieved by combustor design, and advanced air pollution control devices. The commercial plant design described herein is a combined cycle using either a frame-type gas turbine or an intercooled aeroderivative with clean air as the working fluid. The air is heated by a coal-fired high temperature advanced furnace (HITAF). The best performance from the cycle is achieved by using a modern aeroderivative gas turbine, such as the intercooled FT4000. A simplified schematic is shown. In the UTRC HIPPS, the conversion efficiency for the heavy frame gas turbine version will be 47.4% (HHV) compared to the approximately 35% that is achieved in conventional coal-fired plants. This cycle is based on a gas turbine operating at turbine inlet temperatures approaching 2,500 F. Using an aeroderivative type gas turbine, efficiencies of over 49% could be realized in advanced cycle configuration (Humid Air Turbine, or HAT). Performance of these power plants is given in a table.

Geothermal energy at Long Beach Naval Shipyard and Naval Station and at Seal Beach Naval Weapons Station, California. Final Report 1  

SciTech Connect

The purpose of this project was to determine and evaluate sources of geothermal energy at two military bases in southern California, the Long Beach Naval Shipyard and Naval Station and the Seal Beach Naval Weapons Station. One part of the project focused on the natural geothermal characteristics beneath the naval bases. Another part focused on the geothermal energy produced by oilfield operations on and adjacent to each base. Results of the study are presented here for the US Department of the Navy to use in its program to reduce its reliance on petroleum by the development of different sources of energy. The project required research of various reports and data, both published and unpublished, particularly those of the California Department of Conservation, Division of Oil and Gas and of oil companies with leases on or adjacent to the naval bases. Important field investigations included the measurement of well-head temperatures of fluids produced from selected oil wells at each naval base and a detailed gravity survey of the Seal Beach naval base and vicinity. The well-head temperatures were needed to evaluate individual wells as sources of geothermal energy, while the gravity survey attempted to discover subsurface geologic structures that might contain geothermal fluids of temperatures higher than those predicted by the regional geothermal conditions.

Ecological studies of wood-boring bivalves in the vicinity of the Oyster Creek Nuclear Generating Station. Progress report, March-May 1982  

SciTech Connect

The species composition, distribution, and population dynamics of wood-boring bivalves are being studied in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Untreated wood test panels are used to collect organisms at 12 stations. Physiological tolerances of 3 species are also under investigation in the laboratory. Competition among the species is being analyzed. The adult population of Teredo bartschi survived the winter and spring of 1981-1982 better than it did previous cold periods without a thermal effluent. Lack of an effluent was due to a prolonged outage of the generating station. There was no spring outbreak of shipworms. The introduced species appears established at one station near but outside of Oyster Creek. Three teredinid species coexist in Oyster Creek. Larvae of T. bartschi and T. navalis have similar responses to reduced salinity. Bankia gouldi is the fastest-growing of the teredinids found in New Jersey, and as the lowest annual mortality.

Automated visual inspection stations for next-generation semiconductor package quality control  

NASA Astrophysics Data System (ADS)

In the last several years, the semiconductor industry has come to the realization that the package into which a die is placed is at least as critical to the performance of the complete electronic system as the die itself. This realization has led to an explosive effort across the entire industry to advance the state-of-the-art in semiconductor packaging. To date, this effort has already produced semiconductor packaging options on the scale of the die (i.e., chip scale packaging -- CSP). While CSPs and other advanced packaging techniques provide improved electronic system performance, they also increase the quality control burden (despite the highly automated processes used to manufacture the packages, quality control remains, for the most part, a manual operation). This paper addresses the necessary requirements of automated visual inspection (AVI) for quality control of current and future semiconductor packaging. The necessary requirements of the station are subdivided into two categories: those pertaining to the hardware platform, and those pertaining to the software reasoning engine. Hardware requirements are discussed in terms of finding the best match between commercial, off-the- shelf, hardware components and a given inspection application. Components reviewed include: imagers, optics, illumination systems, auto-focus/alignment systems, material handlers, parallel image preprocessors, and host computers. Applications reviewed include: pin grid array (PGA), ball grid array (BGA), and flip-chip package inspection. Also discussed in the hardware section are options that may be used when commercial components are not adequate. Software requirements are discussed in terms of the functionality required to provide accurate, real-time characterization of package quality, to gain operator acceptance, and to produce meaningful statistics for use in process control.

Ginna Station steam generator U-bend tube analysis for chemical cleaning data

This report discusses a potential cause of the decrease in steam pressure affecting many nuclear plant recirculating steam generators which is the buildup of deposit on the outside surfaces of the tubing. This deposit layer, if thick enough, acts to insulate'' the tube, resulting in decreased heat transfer from the reactor coolant to the secondary fluid. At some point in time, fouling may thus degrade thermal performance to a level that warrants chemical cleaning of the steam generators. To help in evaluating the extent and effect of deposit buildup in Rochester Gas Electric's (RGE) Ginna Plant steam generators, sections of one outer row Unbend tube were removed. The tube specimens were examined and tested to: (1) determine the deposit morphology (density, thickness, composition); (2) determine the effect of the deposit on the overall heat transfer coefficients; and (3) obtain the basic solubility and dissolution data needed to chemically clean the tube sections. Results of the laboratory examination and test program indicate that the deposit in the U-bend area is a duplex scale approximately 8--9 mils thick. The inner layer ({approximately}2 mils thick) is relatively non-porous and is composed primarily of calcium, phosphorous, and oxygen resulting from the plant's initial use of a phosphate based water treatment program. The outer layer is primarily magnetite with copper particles dispersed throughout. Bench scale tests confirmed that the solubility of the deposit in the EPRI/SGOG solvents is high ({approximately}98 %) with excellent dissolution kinetics. Heat transfer tests performed at prototypical steam generator pressures and temperatures and at nucleate boiling conditions indicate that the overall heat transfer coefficient of the tube specimens increased by {approximately}34 % when the deposit was removed with the EPRI/SGOG chemical cleaning process.

Using waste-to-energy to repower utility electrical generating stations  

SciTech Connect

The US Department of Energy in its May 1992 analysis of energy from municipal solid waste (MSW) concluded that as an energy resource, MSW is unique. It can be used to produce energy, displace fossil fuel and improve the environment by reducing the amount of wastes that must be landfilled and by conserving energy and natural resources. In addition, because MSW is considered a renewable biomass fuel, it meets most state public utility commission requirements for alternative fuel usage. Moreover, as a domestic resource, energy dollars and their positive effect on the economy are kept at home. Ogden Projects (Ogden) operates 25 of the more than 140 modern waste-to-energy facilities in the United States today. In fact, because of Ogden's unique ability to closely match utility boiler steam requirements with its proprietary massburn technology, Ogden has emerged as the industry leader in utility repowering using municipal solid waste. Pertinent equipment upgrades designed to provide long-term, reliable electrical generation in full compliance with electrical generation in full compliance with the Clean Air Act Amendments allow the repowered facility to provide the least cost of generation to the utility. Current installations and the benefits of waste-to-energy repowering are described.

The potential of biomass and animal waste of Turkey and the possibilities of these as fuel in thermal generating stations  

SciTech Connect

In this study, the potential of important biomass energy sources and animal solid wastes of Turkey were determined and the potential of these as a source of fuel in thermal generating stations to produce electricity was studied. The effects of biomass and lignite coal usage on the environment were reported comparatively. Considering total cereal products and fatty seed plants, approximately 50--65 million tons per year of biomass and 11,051 million tons of solid matter animal waste are produced, and 60% of biomass is seen as possible to use for energy. The primary energy of applicable biomass was evaluated as 467--623 Peta Joule (PJ) and the energy of animal residues as 50,172 PJ. This amount of energy is equal to 22--27% of Turkey`s annual primary energy consumption, (6,308 million tons of oil equivalent).

Seismic structural fragility investigation for the San Onofre Nuclear Generating Station, Unit 1 (Project I); SONGS-1 AFWS Project  

SciTech Connect

An evaluation of the seismic capacities of several of the San Onofre Nuclear Generating Station, Unit 1 (SONGS-1) structures was conducted to determine input to the overall probabilistic methodology developed by Lawrence Livermore National Laboratory. Seismic structural fragilities to be used as input consist of median seismic capacities and their variabilities due to randomness and uncertainty. Potential failure modes were identified for each of the SONGS-1 structures included in this study by establishing the seismic load-paths and comparing expected load distributions to available capacities for the elements of each load-path. Particular attention was given to possible weak links and details. The more likely failure modes were screened for more detailed investigation.

Environmental radiological studies downstream from the Rancho Seco Nuclear Power Generating Station, 1985  

SciTech Connect

Information compiled in 1985 while assessing the environmental impact of radionuclides previously discharged with aqueous releases from the Rancho Seco Nuclear Power Generating Plant is presented. In October 1984, the quantities of gamma-emitting radionuclides in water discharged to Clay Creek from the plant were reduced below operationally defined detection limits for liquid effluents. However, radionuclides previously discharged persist in the downstream environment and are found in many aquatic dietary components. /sup 134/Cs and /sup 137/Cs are the primary gamma-emitting radionuclides detected in the edible flesh of different fish, crayfish, and frogs. Coefficients for exponential equations are generated, from a least square analysis, that relate the change in concentration of /sup 137/Cs in fish to distance downstream and time between March and October 1985. Concentrations of /sup 137/Cs in surface creek sediments also decreased in the downstream direction much in the same manner as concentrations decreased in fish. However, there was no significant difference in the radiocesium concentrations in surface sediements collected from comparable locations during both 1984 and 1985.

Ecological studies of wood-boring bivalves in the vicinity of the Oyster Creek Nuclear Generating Station. Progress report, 1 March-31 May 1980  

SciTech Connect

The species composition, distribution, and population dynamics of wood-boring bivalves are being studied in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Untreated wood test panels are used to collect organisms at 12 stations. Physiological tolerances of 3 species are also under investigation in the laboratory. The native species Teredo navalis and Bankia gouldi coexist with the introduced T. bartschi in Oyster Creek, at the mouth of Forked River and on the coast of the bay between the two creeks. Heavy mortality occurred in all species during winter and spring when the generating station was not operating. Temperature and salinity tolerance tests begun during April and May, 1980, were not completed by the end of May because the adult shipworms proved to be very resistant to drastic changes in these physical parameters.

The species composition, distribution, and population dynamics of wood-boring bivalves are being studied in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Untreated wood test panels are used to collect organisms at 12 stations. Physiological tolerances of 3 species are also under investigation in the laboratory. Relative destructiveness and competition among the species are being analyzed. Teredo bartschi caused almost complete destruction of panels in Oyster Creek during the summer of 1979. Reproduction and settlement of this species continued into October. The native species Teredo navalis and Bankia gouldi coexist with T. bartschi in Oyster Creek. The greatest shipworm damage is in Oyster Creek. Heavy mortality occurs in all species during winter, especially in winters such as 1979-80 when the generating station is not operating. Adults of all three species can survive for at least 30 days at salinities from 5 to 45 parts per thousand by weight. They can withstand abrupt salinity changes.

Proposal for all-optical generation of multiple-frequency millimeter-wave signals for RoF system with multiple base stations using FWM in SOA.  

PubMed

An approach for the multiple-frequency millimeter-wave (mm-wave) signals generation is proposed and demonstrated, specifically, which can be applied to a radio-over-fiber (RoF) system with multiple base stations (BSs). In this scheme, optical double sideband (ODSB) modulation is achieved using a Mach-Zehnder modulator (MZM) to generate the two-sideband signals. New frequencies of the optical signals are obtained by using four-wave mixing (FWM) in a semiconductor optical amplifier (SOA). At the BSs, two different frequencies are achieved using a comb optical filter (COF), and which then input a photodiode (PD) to generate the mm-wave signals with the frequencies of 20, 40 or 60 GHz for different BSs, by mixing of these frequencies components. Experimental results verify that the proposed multiple-frequency mm-wave signals generation scheme for a RoF system with multiple base stations can work properly. PMID:21934756

Structural review of the San Onofre Nuclear Generation Station Unit 1 containment structure under combined loads. Systematic Evaluation Program  

SciTech Connect

This report is a structural assessment of the containment structure of the San Onofre Nuclear Generation Station Unit 1, performed for the Nuclear Regulatory Commission as part of the Systematic Evaluation Program (SEP). The San Onofre assessment focused on the overall structural integrity of the containment structure under a safe shutdown earthquake an a postulated design basis accident. The safe shutdown earthquake was represented by the Housner Spectra, scaled to 0.67 g peak ground acceleration. The postulated design basis accident was either a loss of coolant accident or a main steam line break. Several combined stresses were evaluated for their adherence to the 1980 edition of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code allowables. All the calculated stress intensities were found to be acceptable according to this code except the general primary membrane stress due to combined dead and pressure loads under level A service limits. Because the containment structure was previously tested under combined dead and pressure loads for a higher peak pressure than the one used here, this study concluded that it was acceptable.

Space station power system  

NASA Technical Reports Server (NTRS)

It is pointed out that space station planning at NASA began when NASA was created in 1958. However, the initiation of the program for a lunar landing delayed the implementation of plans for a space station. The utility of a space station was finally demonstrated with Skylab, which was launched in 1972. In May 1982, the Space Station Task Force was established to provide focus and direction for space station planning activities. The present paper provides a description of the planning activities, giving particular attention to the power system. The initial space station will be required to supply 75 kW of continuous electrical power, 60 kW for the customer and 15 kW for space station needs. Possible alternative energy sources for the space station include solar planar or concentrator arrays of either silicon or gallium arsenide.

The current TOGA has been on the International Space Station since November 2008. Functional checkout and operations revealed complex operating considerations. Specifically, failure of the hydrogen catalyst resulted in the development of an innovative oxidation analysis method. This method reduces the activation time and limits the hydrogen produced during analysis, while retaining the ability to indicate TOC concentrations within 25% accuracy. Subsequent testing and comparison to archived samples returned from the Station and tested on the ground yield high confidence in this method, and in the quality of the recovered water.

Multi-service radio-over-fiber system with multiple base-station groups enabled by scalable generation of multi-frequency MMWs  

NASA Astrophysics Data System (ADS)

In this paper, we propose and verify a novel hierarchical radio-over-fiber (RoF) system with multiple base-station groups (BSGs). The proposed RoF system has a two-stage structure to provide the access of multiple services for each BS in BSGs, utilizing the scalable generation of multi-frequency millimeter-waves (MMWs). By using the four-wave mixing (FWM) effect in a semiconductor optical amplifier (SOA), multi-frequency MMWs can be generated with the scalability. The obtained results successfully verify the feasibility of our proposed multi-service access RoF system with BSGs.

RF Environment Test on a Proposed Site for the Sensor Station of the Next Generation Satellite Navigation System, GALILEO: I. The Result of the Test on the Vicinity of KVN Tamla Site in the Year of 2006 by KASI  

NASA Astrophysics Data System (ADS)

As the next generation of global satellite navigation system, the Galileo project is about to witness an initial orbit validation stage as the successful test of navigation message transmission from Giove-A in 2007. The Space Geodesy division and the Radio Astronomy division of the Korea Astronomy & Space Science Institute had collaborated on the field survey for the Galileo Sensor Station (GSS) RF environment of the proposed site near Jeju Tamla University from August 3rd to August 5th, 2006. The power spectrums were measured in full-band (800 2000 MHz) and in-band (E5, E6 and L1 band) in frequency domain for 24 hours respectively. Finally, we performed a time domain analysis to characterize strong in-band interference source based on the result of the previous step.

Ecological studies of wood-boring bivalves in the vicinity of the Oyster Creek Nuclear Generating Station. Progress report, September-November 1981  

SciTech Connect

The species composition, distribution, and population dynamics of wood-boring bivalves are being studied in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Untreated wood test panels are used to collect organisms at 12 stations. Physiological tolerances of 3 species are also under investigation in the laboratory. Competition among the species is being analyzed. In the fall of 1981, Teredo bartschi remained in Oyster Creek despite continuous prolonged outages of the Oyster Creek Nuclear Generating Station. It did not spread to Forked River or Waretown as it had done in other years when the effluent was present. The peak in larval production and settlement of T. bartschi occurred between September and October. Settlement of shipworms occurred on no monthly panels except those in Oyster Creek during the period of this report. Laboratory experiments revealed that T. bartschi becomes inactive at 5/sup 0/C (24/sup 0///sub 00/) and T. navalis shows signs of osmotic stress below 10/sup 0///sub 00/ at 18/sup 0/C. The shipworms in Barnegat Bay do not show a preference for settling at the mudline when the substrate is not limited.

Steam generator group project: Task 13 final report: Nondestructive examination validation  

SciTech Connect

The Steam Generator Group Project (SGGP) was a multi-task effort using the retired-from-service Surry 2A pressurized water reactor steam generator as a test bed to investigate the reliability and effectiveness of in-service nondestructive eddy current (EC) inspection equipment and procedures. The information developed provided the technical basis for recommendations for improved in- service inspection and tube plugging criteria of steam generators. This report describes the results and analysis from Task 13--NDE Validation. The primary objective of Task 13 was to validate the EC inspection to detect and size tube defects. Additional objectives were to assess the nature and severity of tube degradation from all regions of the generator and to measure the remaining integrity of degraded specimens by burst testing. More than 550 specimens were removed from the generator and included in the validation studies. The bases for selecting the specimens and the methods and procedures used for specimen removal from the generator are reported. Results from metallurgical examinations of these specimens are presented and discussed. These examinations include visual inspection of all specimens to locate and identify tube degradation, metallographic examination of selected specimens to establish defect severity and burst testing of selected specimens to establish the remaining integrity of service-degraded tubes. Statistical analysis of the combined metallurgical and EC data to determine the probability of detection (POD) and sizing accuracy are reported along with a discussion of the factors which influenced the EC results. Finally, listings of the metallurgical and corresponding EC data bases are given. 12 refs., 141 figs., 24 tabs.

Coal conversion engineering analysis for Central Hudson Gas and Electric Corporation, Danskammer Generating Station, Units 3 and 4. Final report  

SciTech Connect

The technical and economic feasibility of converting the Danskammer Power Plant at Roseton, NY from oil- to coal-firing was examined. This plant, built in 1950, was converted from coal- to oil-firing in 1971. Evaluation of the plant showed that oil-to-coal conversion is technically feasible, but modifications or additions to existing plant equipment would be required to meet coal handling needs and pollution control regulations. With no flue gas desulfurization equipment the 1980 cost of plant reconversion is estimated as $50.3 million. A FGD system would require an additional $40 million in direct costs. The total time estimated for engineering, construction, and licensing is 57 months. (LCL)

Protostellar Feedback and Final Mass of the Second-generation Primordial Stars  

NASA Astrophysics Data System (ADS)

The first stars in the universe ionized the ambient primordial gas through various feedback processes. "Second-generation" primordial stars potentially form from this disturbed gas after its recombination. In this Letter, we study the late formation stage of such second-generation stars, where a large amount of gas accretes onto the protostar and the final stellar mass is determined when the accretion terminates. We directly compute the complex interplay between the accretion flow and stellar ultraviolet (UV) radiation, performing radiation-hydrodynamic simulations coupled with stellar evolution calculations. Because of more efficient H2 and HD cooling in the pre-stellar stage, the accretion rates onto the star are 10 times lower than in the case of the formation of the first stars. The lower accretion rates and envelope density result in the occurrence of an expanding bipolar H II region at a lower protostellar mass M * ~= 10 M ?, which blows out the circumstellar material, thereby quenching the mass supply from the envelope to the accretion disk. At the same time the disk loses mass due to photoevaporation by the growing star. In our fiducial case the stellar UV feedback terminates mass accretion onto the star at M * ~= 17 M ?. Although the derived masses of the second-generation primordial stars are systematically lower than those of the first generation, the difference is within a factor of only a few. Our results suggest a new scenario, whereby the majority of the primordial stars are born as massive stars with tens of solar masses, regardless of their generations.

Submerged AUV Charging Station  

NASA Technical Reports Server (NTRS)

Autonomous Underwater Vehicles (AUVs) are becoming increasingly important for military surveillance and mine detection. Most AUVs are battery powered and have limited lifetimes of a few days to a few weeks. This greatly limits the distance that AUVs can travel underwater. Using a series of submerged AUV charging stations, AUVs could travel a limited distance to the next charging station, recharge its batteries, and continue to the next charging station, thus traveling great distances in a relatively short time, similar to the Old West Pony Express. One solution is to use temperature differences at various depths in the ocean to produce electricity, which is then stored in a submerged battery. It is preferred to have the upper buoy submerged a reasonable distance below the surface, so as not to be seen from above and not to be inadvertently destroyed by storms or ocean going vessels. In a previous invention, a phase change material (PCM) is melted (expanded) at warm temperatures, for example, 15 C, and frozen (contracted) at cooler temperatures, for example, 8 C. Tubes containing the PCM, which could be paraffin such as pentadecane, would be inserted into a container filled with hydraulic oil. When the PCM is melted (expanded), it pushes the oil out into a container that is pressurized to about 3,000 psi (approx equals 20.7 MPa). When a valve is opened, the high-pressure oil passes through a hydraulic motor, which turns a generator and charges a battery. The low-pressure oil is finally reabsorbed into the PCM canister when the PCM tubes are frozen (contracted). Some of the electricity produced could be used to control an external bladder or a motor to the tether line, such that depth cycling is continued for a very long period of time. Alternatively, after the electricity is generated by the hydraulic motor, the exiting low-pressure oil from the hydraulic motor could be vented directly to an external bladder on the AUV, such that filling of the bladder causes the AUV to rise, and emptying of the bladder allows the AUV to descend. This type of direct buoyancy control is much more energy efficient than using electrical pumps in that the inefficiencies of converting thermal energy to electrical energy to mechanical energy is avoided. AUV charging stations have been developed that use electricity produced by waves on floating buoys and that use electricity from solar photovoltaics on floating buoys. This is the first device that has absolutely no floating or visible parts, and is thus impervious to storms, inadvertent ocean vessel collisions, or enemy sabotage.

Socioeconomic impacts of nuclear generating stations - Diablo Canyon case study. Technical report for 1 Oct 78-4 Jan 82  

SciTech Connect

This report documents a case study of the socioeconomic impacts of the construction and operation of the Diablo Canyon nuclear power station. It is part of a major post-licensing study of the socioeconomic impacts at twelve nuclear power stations. The case study covers the period beginning with the announcement of plans to construct the reactor and ending in the period, 1980-81. The case study deals with changes in the economy, population, settlemeent patterns and housing, local government and public services, social structure, and public response in the study during the construction/operation of the reactor. A regional modeling approach is used to trace the impact of construction/operation on the local economy, labor market, and housing market. Emphasis in the study is on the attribution of socioeconomic impacts to the reactor or other causal factors. As part of the study of local public response to the construction/operation of the reactor, the effects of the Three Mile Island accident are examined.

Evaluation of alternative alloys for PWR steam generator tubing. Final report  

SciTech Connect

This final report summarizes the results of a project to evaluate alternative alloys for use as PWR steam generator tubing. A literature survey identified alloys 690 and 800 in the mill annealed condition and alloys 600 and 690 after annealing at 705/sup 0/C (1300/sup 0/F) for 15 hours as candidate alloys. Mill annealed alloy 600 was included as a control. C-ring tests were carried out in four secondary and one primary water environment. In the mill annealed condition, alloy 800 was more resistant to stress corrosion cracking than alloys 600 and 690. A low temperature anneal at 705/sup 0/C (1300/sup 0/F) improved the stress corrosion resistance of all the alloys. The greatest improvement was noted in alloy 690 where no failures were observed in any of the specimens even after annealing for only 4 hours. A test technique was developed to examine the stress corrosion behavior of a material by slowly internally pressurizing a section of tubing while the exterior was exposed to a simulated steam generator environment. Cracking of all alloys tested could be initiated in less than 20 days. The results indicate that alloy 600 and alloy 690 given a low temperature anneal at 705/sup 0/C (1300/sup 0/F) for 15 hours are more resistant to stress corrosion cracking than either mill annealed alloy 600 or mill annealed alloy 800. The degree of susceptibility of an alloy in this type of test may be dependent on pressurization rate.

This paper provides an overview of several recent ISS educational payloads and activities. The expected outcomes of the project, consistent with those of the NASA Office of Education, are also described. NASA performs numerous education activities as part of its ISS program. These cover the gamut from formal to informal educational opportunities in grades Kindergarten to grade 12, Higher Education (undergraduate and graduate University) and informal educational venues (museums, science centers, exhibits). Projects within the portfolio consist of experiments performed onboard the ISS using onboard resources which require no upmass, payloads flown to ISS or integrated into ISS cargo vehicles, and ground based activities that follow or complement onboard activities. Examples include ground based control group experiments, flight or experiment following lesson plans, ground based activities involving direct interaction with ISS or ground based activities considering ISS resources in their solution set. These projects range from totally NASA funded to projects which partner with external entities. These external agencies can be: other federal, state or local government agencies, commercial entities, universities, professional organizations or non-profit organizations. This paper will describe the recent ISS education activities and discuss the approach, outcomes and metrics associated with the projects.

Ecological studies of wood-boring bivalves in the vicinity of the Oyster Creek Nuclear Generating Station. Progress report, June-August 1982  

SciTech Connect

The species composition, distribution, and population dynamics of wood-boring bivalves are being studied in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Untreated wood test panels are used to collect organisms at 12 stations. Physiological tolerances of 3 species are also under investigation in the laboratory. Competition among the species is being analyzed. Adult populations of Teredo bartschi existed in both Oyster Creek and Forked River in the summer of 1982, but the species was rare. There was no large settlement of this or any other teredinid species in Barnegat Bay. Teredo navalis was the most common species in the monthly panels. The fouling community reached its maximum yearly diversity in June-July. There was a thermal effluent causing a ..delta..T of 3 to 4/sup 0/C during most of the summer, and salinity in Oyster Creek and Forked River was similar to that of Barnegat Bay. The lack of a shipworm outbreak in 1982 may be related to the low ..delta..T in summer, plus the lack of a thermal effluent in the preceding winter-spring period.

The growth, distribution, and species composition of marine borers (primarily shipworms) and fouling organisms are being studied in the vicinity of the Oyster Creek Nuclear Generating Station, Barnegat Bay, New Jersey. Untreated wood test panels are used to collect organisms at 18 localities. Our most recent findings covering June-August, 1979, are that at least one subtropical species of the borer family Teredinidae, Teredo bartschi, continues to live in Oyster Creek and can breed in Forked River, although many die off in winter in Forked River and the species may have to recolonize. A few of the subtropical T. furcifera also survive in Oyster Creek but cause negligible damage at present, compared with T. bartschi. The summer, 1979, outbreak of T. bartschi in Oyster Creek was severe, causing nearly total destruction to wood panels. The breeding season for T. bartschi was the same as in 1978. Some fouling organisms were present in Oyster Creek that are absent in control creek stations due to low salinity.

Development of a System to Generate Near Real Time Tropospheric Delay and Precipitable Water Vapor in situ at Geodetic GPS Stations, to Improve Forecasting of Severe Weather Events  

NASA Astrophysics Data System (ADS)

We describe a system under development for generating ultra-low latency tropospheric delay and precipitable water vapor (PWV) estimates in situ at a prototype network of geodetic GPS sites in southern California, and demonstrating their utility in forecasting severe storms commonly associated with flooding and debris flow events along the west coast of North America through infusion of this meteorological data at NOAA National Weather Service (NWS) Forecast Offices and the NOAA Earth System Research Laboratory (ESRL). The first continuous geodetic GPS network was established in southern California in the early 1990s and much of it was converted to real-time (latency <1s) high-rate (1Hz) mode over the following decades. GPS stations are multi-purpose and can also provide estimates of tropospheric zenith delays, which can be converted into mm-accuracy PWV using collocated pressure and temperature measurements, the basis for GPS meteorology (Bevis et al. 1992, 1994; Duan et al. 1996) as implemented by NOAA with a nationwide distribution of about 300 GPS-Met stations providing PW estimates at subhourly resolution currently used in operational weather forecasting in the U.S. We improve upon the current paradigm of transmitting large quantities of raw data back to a central facility for processing into higher-order products. By operating semi-autonomously, each station will provide low-latency, high-fidelity and compact data products within the constraints of the narrow communications bandwidth that often occurs in the aftermath of natural disasters. The onsite ambiguity-resolved precise point positioning solutions are enabled by a power-efficient, low-cost, plug-in Geodetic Module for fusion of data from in situ sensors including GPS and a low-cost MEMS meteorological sensor package. The decreased latency (~5 minutes) PW estimates will provide the detailed knowledge of the distribution and magnitude of PW that NWS forecasters require to monitor and predict severe winter storms, landfalling atmospheric rivers, and summer thunderstorms associated with the North American monsoon. On the national level, the ESRL will evaluate the utility of ultra-low resolution GNSS observations to improve NOAA's warning and forecast capabilities. The overall objective is to better forecast, assess, and mitigate natural hazards through the flow of information from multiple geodetic stations to scientists, mission planners, decision makers, and first responders.

Nonlinear Excitation Control of Two Sets of Adjustable Speed Generators/Motors at Rotary Type Frequency Converter Station for Performance Improvement of Power System Dynamics  

NASA Astrophysics Data System (ADS)

There are 50Hz and 60Hz power systems in Japan, which are interconnected by power electronics based static type frequency converter station. Frequency converter can be realized by using Adjustable Speed Generators/Motors (ASGMs), which are excited by AC voltage, and so-called rotary type frequency converter. The rotary type frequency converter can also function as a power system stabilizer by effectively utilizing rotational energy stored in rotors. Nonlinear excitation control for the rotary type frequency converter is proposed to enhance performance of the rotational energy utilization and to improve stability of power system. The control performance is examined for a power system model by digital dynamic simulation. It is made clear that the proposed nonlinear excitation control is effective even though local information of the rotary type frequency converter is just used and that it has robustness against various load flow conditions.

Space station  

NASA Technical Reports Server (NTRS)

The history of American space flight indicates that a space station is the next logical step in the scientific pursuit of greater knowledge of the universe. The Space Station and its complement of space vehicles, developed by NASA, will add new dimensions to an already extensive space program in the United States. The Space Station offers extraordinary benefits for a comparatively modest investment (currently estimated at one-ninth the cost of the Apollo Program). The station will provide a permanent multipurpose facility in orbit necessary for the expansion of space science and technology. It will enable significant advancements in life sciences research, satellite communications, astronomy, and materials processing. Eventually, the station will function in support of the commercialization and industrialization of space. Also, as a prerequisite to manned interplanetary exploration, the long-duration space flights typical of Space Station missions will provide the essential life sciences research to allow progressively longer human staytime in space.

Environmental radiological studies conducted during 1986 in the vicinity of the Rancho Seco Nuclear Power Generating Station  

SciTech Connect

This report summarizes the information compiled in 1986 for our assessment of the environmental impact of radionuclides discharged with aqueous releases from the Rancho Seco Nuclear Power Generating Plant. In October 1984, a liquid-effluent control program was initiated that significantly reduced the quantities of radionuclides discharged with liquid waste from the plant. However, results from our sampling program in 1986 indicate that previously discharged radionuclides persist in the downstream environment and are found in many aquatic dietary components although at concentrations much lower than those measured in 1984 and 1985. The greatly reduced activities in the dietary components from the aquatic environment attest to the effectiveness of the liquid-effluent control program. Concentrations in the flesh of fish from the creeks have decreased over time and with distance from the plant outfall. The mean concentration of /sup 137/Cs in fish collected from Laguna Creek at locations more than 7.5 km from Rancho Seco is now comparable to the concentration determined in fresh-water fish randomly selected from Chicago, Illinois, markets. By August 1986, the mean concentration of /sup 137/Cs in the flesh of bluegill had fallen to 7% of the concentration measured in fish from comparable locations in 1984 and was 30% of the mean concentration measured in these fish during August 1985. Stable potassium in the water plays a major role in the accumulation of /sup 137/Cs by fish. Concentrations of /sup 137/Cs in the surface sections of creek sediments also declined between the end of 1984 and 1986 with an effective half-life of approximately 2 y. Surface soils collected around a perimeter 11 km from Rancho Seco and from ranchlands closer to the plant showed only concentrations of /sup 137/Cs originating from global fallout. Soils previously irrigated with Clay Creek water retain levels of both /sup 134/Cs and /sup 137/Cs.

Processing, packaging, and storage of non-fuel-bearing components from the rod consolidation demonstration at Prairie Island Nuclear Generating Station  

SciTech Connect

Many nuclear power plants are running out of space in their spent-fuel pools, and by the early 1990s, existing spent-fuel storage capacity must be supplemented at over 20 commercial nuclear plants. Rod consolidation and dry storage, either individually or in combination, are the only viable alternatives to meet the spent-fuel storage requirements until a government storage facility or repository is established. The Prairie Island Nuclear Generating Station operated by Northern States Power Company (NSP) is in this predicament. To meet Prairie Island's storage needs, NSP is evaluating the feasibility of full-scale implementation of spent-fuel consolidation. The technical and economic success of fuel consolidation requires successful and economical processing, storage and disposal of the scrap non-fuel-bearing components (NFBC). In the fall of 1987, NSP initiated a consolidation demonstration program at Prairie Island, during which 29 equipment spent-fuel assemblies were successfully consolidated by Westinghouse. The paper discusses program scope, NFBC characterization and classification, NFBC processing and NFBC segregation and packaging.

Mercury speciation in a coal-fired power plant plume: An aircraft-based study of emissions from the 3640 MW Nanticoke Generating Station, Ontario, Canada  

NASA Astrophysics Data System (ADS)

Coal-fired power plants are one of the principal sources of mercury to the atmosphere. The form this mercury takes is the predominant factor determining its fate after emission. Recent ground-level field and modeling studies suggest that oxidized mercury in stack emissions is converted into elemental mercury in the plume. We present here aircraft-based plume mercury measurements taken by Environment Canada in 2000 at the Nanticoke Generating Station as part of the Health Canada Toxic Substances Research Initiative Metals in the Environment Research Network. Although the average mercury speciation observed in the Nanticoke plume (82% Hg0, 13% Hg(II)(g), 5% Hg(P), by mass) appears to be distinct from the average mercury speciation in the Nanticoke stacks (53% Hg0, 43% Hg(II)(g), 4% Hg(P)), we find that the in-plume elemental mercury concentrations as a whole can be explained by plume dilution after emission. The discrepancy between in-stack and in-plume Hg(II) concentrations is statistically significant, yet is not associated with a transformation of Hg(II) to Hg0. Sampling biases associated with the differing techniques used to measure Hg(II) in-stack and in-plume may reconcile the concentration discrepancy without invoking novel chemical reactions or physical processes. Although the mercury speciation of the Nanticoke plume influences local mercury deposition, the majority of the mercury emitted is transported out of the surrounding area.

Microbial Challenge Testing of Single Liquid Cathode Feed Water Electrolysis Cells for the International Space Station (ISS) Oxygen Generator Assembly (OGA)  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) Oxygen Generator Assembly (OGA) operational performance may be adversely impacted by microbiological growth and biofilm formation over the electrolysis cell membranes. Biofilms could hinder the transport of water from the bulk fluid stream to the membranes and increase the cell resistance resulting in higher cell voltages and a shorter cell life. A microbial challenge test was performed on duplicate single liquid cathode feed electrolyzer cells to evaluate operational performance with increasing levels of a mixture of five bacteria isolated from ISS and Space Shuttle potable water systems. Baseline performance of the single water electrolysis cells was determined for approximately one month with deionized water. Monthly performance was also determined following each inoculation of the feed tank with 100, 1000, 10,000 and 100,000 cells/ml of the mixed suspension of test bacteria. Water samples from the feed tank and recirculating water loops for each cell were periodically analyzed for enumeration and speciation of bacteria and total organic carbon. While initially a concern, this test program has demonstrated that the performance of the electrolysis cell is not adversely impacted by feed water containing the five species of bacteria tested at a concentration measured as high as 1,000,000 colony forming units (CFU)/ml. This paper presents the methodologies used in the conduct of this test program along with the performance test results at each level of bacteria concentration.

Solar power station with semiconductor solar cells for generating electric power is described, wherein the semiconductor solar cells are provided on a member such as a balloon or a kite which carries the solar cells into the air. The function of the balloon or kite can also be fulfilled by a glider or airship. The solar power station can be operated by allowing the system to ascend at sunrise and descend at sunset or when the wind is going to be too strong in order to avoid any demage.

Demonstration of regional discrimination of Eurasian seismic events using observations at Soviet IRIS and CDSN stations. Final report, 29 Mar 89-28 Mar 92  

SciTech Connect

This study has brought together a large, high-quality database of regional signals from Eurasian seismic events, including 38 underground nuclear explosions and 68 earthquakes, recorded at Soviet IRIS and CDSN stations. Characteristics of regional phases observed at each of the Soviet IRIS stations and their relation to propagation and source effects have been analyzed. The high quality of the signals indicates the strong potential of the stations for monitoring events throughout Eurasia. A variety of amplitude and spectral measurements have been performed on the regional signals to discern differences related to source type. We find here differences in Lg/P amplitude ratios and Lg/P spectral ratios between underground nuclear explosions and earthquakes. The fact that such differences are observed for explosions and earthquakes with practically identical propagation paths provides strong evidence that the observed behavior is dependent on source type. However, the regional phase amplitudes and spectral behavior also are affected by geologic structure along the propagation path. A methodology for identifying and adjusting the observations for such propagation effects is described. Similarity of signals for events of a common source type suggests that discriminants effective for some events are likely to work for others from the same general area.

Library of PWR (pressurized-water reactor) steam generator tubing samples: Final report  

SciTech Connect

The PWR Steam Generator Tubing Sample Library is a Steam Generator Owners Group-EPRI program whose objective is to compile a library of well-characterized tubing samples to be used for performance evaluation of inspection systems and for training and qualification of signal interpretation systems. The library was created through the preparation of samples intended to replicate degradation encountered in actual field tubes. A limited number of tube segments removed from actual steam generators are included. Degradation categories include wear, pitting and fatigue cracks, as well as stress corrosion cracking (SCC) and intergranular attack (IGA). Eddy current and ultrasonic inspection techniques, along with supplementary radiography, dye penetrant, and optical techniques were used to characterize the library candidates. Advanced computer-aided NDE data collection, analysis and display techniques were used to assess test results. This report provides details of the library program, with major emphasis on the sampling protocol, characterization of degradation and recommendations for the use and future growth of the library. Also included is a compendium of steam generator tube degradation field observation, describing past destructive examinations of tubes removed for inspection from steam generators, and a description of a physical modeling approach, using mercury (metal) to assess the discontinuity characterization capabilities of a pancake-type eddy current probe. Computerized data analysis and display techniques were used to reconstruct the test results in both two-dimensional color-coded maps and three-dimensional pseudo-isometric plots.

Improved generator for use with low-speed rotating machines. Final report  

SciTech Connect

The goal of this project was to construct a low-technology, maintenance-free dc electrical generator suited for use with low-speed rotating machines such as windmills or waterwheels. The generator consists of permanent magnets affixed to the circumference of the rotating device, and stationary coils mounted on a semicircular frame. As the device rotates, the magnets move past the coils and magnetically induce an ac voltage in the coils. This voltage is rectified and stored in a battery. No gears, belts, or brushes are used, so the generator operates quietly and without maintenance. The purpose of mounting the magnets at the circumference of the rotating device is to achieve high relative velocities between magnets and coils even at slow rotations, in the hope of extracting energy from very light winds or slowly flowing water. Such a generator was constructed as part of a ten-foot-diameter windmill to test the concept. The generator easily reaches charging voltages at low speeds, and operates quietly without mechanical wear. But the charging current is very low in comparison to a wind turbine of conventional design. The experiment allows fundamental design problems to be identified.

Hydrogen evolution monitoring as a measure of steam generator corrosion. Final report  

SciTech Connect

This report describes an on-line hydrogen monitoring technique that can quantify corrosion hydrogen release rates, allowing early detection of denting. The method utilizes the Cambridge Mark IV Dissolved Hydrogen Analyzer to monitor main steam and feedwater hydrogen concentration during normal power operation. Before a close approximation of corrosion hydrogen can be made, three other sources of hydrogen contribution must be quantified: (1) feedwater hydrogen, (2) thermal decomposition of hydrazine, and (3) primary-to-secondary permeation of hydrogen through steam generator tubing. Application of hydrogen monitoring to operating PWR steam generators began in 1976. These applications indicate that hydrogen monitoring is a useful tool for determining steam generator corrosion levels, where gross or general corrosion is present. It cannot be used to indicate the existence of localized attack, such as pitting or cracking of the tube material.

Vibration and wear in steam generator tubes following chemical cleaning. Final report. Volume 2  

SciTech Connect

The buildup of magnetite in the steam generators of some pressurized water reactors (PWRs) has led operators to propose chemical cleaning to remove this product. In some cases, the volume of magnetite formed by the corrosion of the carbon steel has been sufficient to cause ''denting'' or reduction of the outer diameter of the tubes where they pass through the support plates. A profilometry examination of the retired Surry 2A steam generator, conducted at Hanford by Babcock and Wilcox, revealed an average dent in the 40- to 50-mil range, with some tube diameter reduction down to 0.470 inch. In addition, when the magnetite is removed by a chemical cleaning process, the diameter of the hole in the tube support plate is increased even further. The US Nuclear Regulatory Commission (NRC) has expressed concern that an increased clearance between the tube and the tube support plate may result in an increased level of flow-induced vibrations in chemically cleaned steam generators, in cases where the tube support plates are exposed to the cleaning process. This may, in turn, lead to high tube wear rates and unacceptable levels of tube failure. The Pacific Northwest Laboratory (PNL) is supporting the NRC staff in addressing the effects of increased tube/tube-support clearances. The objective of PNL's work is to provide NRC with criteria with which to evaluate licensees' specific proposals for chemical cleaning of steam generators.

ILRS Station Reporting  

NASA Technical Reports Server (NTRS)

Network stations provided system configuration documentation upon joining the ILRS. This information, found in the various site and system log files available on the ILRS website, is essential to the ILRS analysis centers, combination centers, and general user community. Therefore, it is imperative that the station personnel inform the ILRS community in a timely fashion when changes to the system occur. This poster provides some information about the various documentation that must be maintained. The ILRS network consists of over fifty global sites actively ranging to over sixty satellites as well as five lunar reflectors. Information about these stations are available on the ILRS website (http://ilrs.gsfc.nasa.gov/network/stations/index.html). The ILRS Analysis Centers must have current information about the stations and their system configuration in order to use their data in generation of derived products. However, not all information available on the ILRS website is as up-to-date as necessary for correct analysis of their data.

At the request of the Naval Facilities Engineering Command (NAVFAC), Southern Division, Charleston, SC, the U.S. Army Engineer Waterways Experiment Station (WES) conducted the initial field trial of the Site Characterization and Analysis Penetrometer System (SCAPS) at Jacksonville Naval Air Station (NAS), Jacksonville FL. This work was carried out by a field crew consisting of personnel from WES and the Naval Ocean Systems Center during the period of 16 July 1990 to 14 August 1990. The SCAPS investigation at the Jacksonville NAS has two primary objectives: (a) to provide data that could be useful in formulating remediation plans for the facility and (b) to provide for the initial field trial of the SCAPS currently under development by WES for the U.S. Army Toxic and Hazardous Materials Agency (USATHAMA), now the U.S. Army Environmental Center. The original concepts for the SCAPS was to develop an integrated site screening characterization system whose capabilities would include (a) surface mapping, (b) geophysical surveys using magnetic, induced electromagnetic, and radar instruments, (c) measurements of soil strength, soil electrical resistivity, and laser-induced soil fluorometry Cone penetrometer, Site Characterization and Analysis Laser Induced Fluorescence(LIF), Penetrometer System(SCAPS) POL Contamination, using screening instrumentation mounted in a soil penetrometer, (d) soil and fluid samplers, and (e) computerized data acquisition, interpretation, and visualization. The goal of the SCAPS program is to provide detailed, rapid, and cost-effective surface and subsurface data for input to site assessment/remediation efforts.

Transition metal catalysis in the generation of petroleum and natural gas. Final report  

SciTech Connect

This project originated on the premise that natural gas could be formed catalytically in the earth rather than thermally as commonly believed. The intention was to test this hypothetical view and to explore generally the role of sedimentary metals in the generation of light hydrocarbons (C1 - C9). We showed the metalliferous source rocks are indeed catalytic in the generation of natural gas. Various metal compounds in the pure state show the same levels of catalytic activity as sedimentary rocks and the products are identical. Nickel is particularly active among the early transition metals and is projected to remain catalytically robust at all stages of catagenesis. Nickel oxide promotes the formation of n-alkanes in addition to natural gas (NG), demonstrating the full scope of the hypothetical catalytic process: The composition of catalytic gas duplicates the entire range of natural gas, from so-called wet gas to dry gas (60 to 95+ wt % methane), while gas generated thermally is consistently depleted in methane (10 to 60 wt % methane). These results support the view that metal catalysis is a major pathway through which natural gas is formed in the earth.

Los Alamos Plutonium Facility newly generated tru waste certification. Final revised version 3/97  

SciTech Connect

This paper presents an overview of the activities being planned and implemented to certify newly generated contact handled transuranic (TRU) waste produced by Los Alamos National Laboratory`s (LANL`s) Plutonium Facility. Certifying waste at the point of generation is the most important cost and labor saving step in the WIPP certification process. The pedigree of a waste item is best known by the originator of the waste and frees a site from many of the expensive characterization activities associated with legacy waste. Through a cooperative agreement with LANLs Waste Management Facility and under the umbrella of LANLs WIPP-related certification and quality assurance documents, the Plutonium Facility will be certifying most of its own newly generated waste. Some of the challenges faced by the Plutonium Facility in preparing to certify TRU waste include the modification and addition of procedures to meet WIPP requirements, standardizing packaging for TRU waste, collecting processing documentation from operations which produce TRU waste, and developing ways to modify waste streams which are not certifiable in their present form.

Final Report---Next-Generation Solvers for Mixed-Integer Nonlinear Programs: Structure, Search, and Implementation  

SciTech Connect

The mathematical modeling of systems often requires the use of both nonlinear and discrete components. Problems involving both discrete and nonlinear components are known as mixed-integer nonlinear programs (MINLPs) and are among the most challenging computational optimization problems. This research project added to the understanding of this area by making a number of fundamental advances. First, the work demonstrated many novel, strong, tractable relaxations designed to deal with non-convexities arising in mathematical formulation. Second, the research implemented the ideas in software that is available to the public. Finally, the work demonstrated the importance of these ideas on practical applications and disseminated the work through scholarly journals, survey publications, and conference presentations.

Investigation of power losses in the 300kw superconductive generator. Final report, January-June 1991  

SciTech Connect

Previous measurements of the current collector power losses in the 3OOkW superconductive generator have shown the losses to be much higher than predicted by theory. The purposes of these experiments was to isolate the source and magnitude of the power losses with more accurate experimental methods and data collection techniques. The losses could then be theoretically extrapolated to predict losses in a full scale machine for ship propulsion. The results showed that the excessive losses were fluid losses due to overfilling of the current collectors with liquid metal, and eddy current losses in the rotor bearings due to the rotation of the electrically conducting balls in the magnetic field.

SciTech Connect

The Moffett Naval Air Station site is on the National Priorities List. A total of 81 areas (landfills, holding ponds, underground storage tanks, sumps, oil/water separators, bermed pits) have been identified in which wastes were placed. Some of these areas are still active disposal or storage areas. On-site contamination consists of trichloroethylene, trichloroethane, and perchloroethylene in ground water and soil, respectively. Polychlorinated biphenyls (PCBs), various pesticides, aviation fuels and oils, and other organic solvents are suspected to be on-site, but data on the concentrations in environmental media are not available. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via contaminated ground water, soil, surface water, and leachate.

Early utility experience with wind power generation. Volume 1. Summary report. Final report  

SciTech Connect

This report is one of three presenting the results of EPRI Research Project 1590-1, Evaluation of Electric Utility Experience with Wind Power Generation. The objective of this project was to develop an improved understanding of wind power generation, in particular the process a utility must undergo to initiate and carry out a wind turbine project. The primary tasks of RP1590-1 were to document and evaluate the experience of two utilities with megawatt-scale wind turbine installations from project inception to the first rotation of the wind turbine. This summary report presents in brief form the experiences of two utilities, the Pacific Gas and Electric Company and the Bonneville Power Administration, with wind turbine projects at Solano County, California and Goodnoe Hills, Washington, respectively. All documents and reports pertaining to the experiences with the wind turbine projects were reviewed and excerpts made of the highlights. Gaps in the documentation were filled by talking with appropriate people. Site visits were conducted to monitor current activity. The information obtained was evaluated for its generic relevance and benefit to other utilities. Condensed descriptions of the projects, a comparison of the projects, and highlights of the utilities' experiences are presented. Some of the insights which might benefit other utility wind programs are identified.

Specification for strontium-90 500-watt(e) radioisotopic thermoelectric generator. Final report  

SciTech Connect

A conceptual design for a demonstration 500-watt(e) radioisotopic thermoelectric generator has been created for the Department of Energy. The design effort was divided into two tasks, viz., create a design specification for a capsule strength member that utilizes a standard Strontium-90 fluoride-filled WESF inner liner, and create a conceptual design for a 500-watt(e) RTG. Both tasks have been accomplished. The strength-member specification was designed to survive an external pressure of 24,500 psi and meet the requirements of special-form radioisotope heat sources. Therefore the capsule can, if desired, be licensed for domestic and international transport. The design for the RTG features a radioisotopic heat source, an array of nine capsules in a tungsten biological shield, four current-technology series-connected thermoelectric-conversion modules, low-conductivity thermal insulation, and a passive finned-housing radiator for waste-heat dissipation. The preliminary RTG specification formulated previous to contract award has been met or exceeded. The power source will generate the required power for the required service period at 28 volts dc with a conversion efficiency of 8%, provided the existing in-pool capsules at WESF meet the assumed thermal-inventory requirements.

Hideout of impurities in steam generators during heat-up and power ascension: Final report  

SciTech Connect

A field test program was performed to measure hideout rates of contaminant species in steam generators during plant heatup and power escalation. Steam generator blowdown, feedwater and main steam samples were collected at three plants. Mass balance calculations were performed using the analytical results from those samples. During plant heatup, sulfate and phosphate were observed to hideout when steaming was initiated. Maximum hideout rates for these specied occurred in the 400 to 550/sup 0/F temperature range and varied from 0.88 to 4.3 mg/hr/ppB in the bulk and 12.2 to 19.1 mg/hr/ppB in the bulk for sulfate and phosphate, respectively. Both hideout and ''apparent'' return of contaminants were indicated by mass balance calculations performed using analytical results of samples collected while at power. The results of these calculations showed sufficient scatter that neither meaningful rates nor power thresholds for the oneset of hideout could be determined for power operation. For plants where sulfates or phosphates are major components of contaminant hideout inventories, isothermal soaks during cooldown and cold fill-soak-drain cycles during cold shutdown are recommended to minimize sulfate and phosphate hideout during subsequent plant heatup.

Optical probe for steam-generator-tube dent measurement. Final report. [PWR  

SciTech Connect

Under Research Project S 181-1, Sigma Research designed an optical profilometer to measure tube denting in steam generators and constructed prototype and field-hardened devices. As the noncontacting, microprocessor-controlled probe is pushed or pulled through tubing at 6 inches (150 mm) per second, the optic section (rotating at 4000 rpm) scans the surface and collects data at 48 points around the circumference. Optics are arranged so that, when data points are focused on a lateral cell, displacements along the cell are proportional to variations in tube radius. Profile data are stored on floppy diskettes and can be called up and displayed on a video monitor in one of three formats that depict deviations from nominal on a magnified scale. Both probes were tested on tube samples provided by the Electric Power Research Institute's Nondestructive Examination (NDE) Center.

Solar-assisted hydrogen generation by photoelectrocatalysis. Final report, September 3, 1982-September 30, 1985  

SciTech Connect

The technical objective of the program was to apply a multidisciplinary approach to systematically elucidate the role of purposely introduced metal electrocatalysts on the photoelectrode surface for enhancing PEC efficiency leading to hydrogen generation. The overall approach was termed photoelectrocatalysis. A variety of photoelectrodes were investigated with emphasis being placed upon p-InP as a model substrate for hydrogen evolution and on n-Fe/sub 2/O/sub 3/ for oxygen evolution. Experimental measurement techniques used in the performance of the program included steady-state and transient photoelectrochemistry, photocapacitance, admittance and Raman spectroscopy together with automatic scanning ellipsometry. Specific features investigated at this interface region included photoelectrode kinetics, semiconductor surface molecular structure, and charge-carrier energetics, together with the energetics and populations associated with electronic surface states.

Proposed Tenaska Washington II Generation Project : Final Environmental Impact Statement: Summary.  

SciTech Connect

BPA is considering whether to purchase electrical power from a proposed privately-owned combustion-turbine electrical generation plant in Washington. The plant would be fired by natural gas and would use combined-cycle technology to generate 240 average megawatts (aMW) of energy. The plant would be developed, owned, and operated by Tenaska Washington Partners II, L.P. The project would be located about 19 kilometers (12 miles) southeast of downtown Tacoma in the Frederickson Industrial Area, Pierce County. The proposed plant would occupy about half of a 6.4-hectare (16-acre) parcel and would be consistent with the industrial character of its surroundings. The proposed site is currently undeveloped and zoned for industrial use by the county. Main environmental concerns identified in the scoping process and in comments on the Draft Environmental Impact Statement (EIS) include: (1) potential air quality impacts, such as emissions and their contribution to the {open_quotes}greenhouse{close_quotes} effect; (2) potential health and safety impacts, such as nuisance odors, plant safety, visibility and heat-emission systems which may affect low-flying planes and potential health effects of electric and magnetic fields; and (3) potential water quality and quantity impacts, such as the amount of wastewater to be discharged, the source and amount of water required for plant operation. These and other issues are discussed in detail in the EIS. The proposed project already includes many features designed to reduce environmental impacts. Based on investigations performed for the EIS, no significant unavoidable adverse environmental impacts associated with the proposed project were identified, and no evidence emerged to suggest that the proposed action is controversial. The EIS is being mailed to numerous agencies, groups, and individuals (see Section 8.0). There will be a 30-day no-action period before any decisions are made and the Record of Decision is signed.

Levels at gaging stations  

USGS Publications Warehouse

Operational procedures at U.S. Geological Survey gaging stations include periodic leveling checks to ensure that gages are accurately set to the established gage datum. Differential leveling techniques are used to determine elevations for reference marks, reference points, all gages, and the water surface. The techniques presented in this manual provide guidance on instruments and methods that ensure gaging-station levels are run to both a high precision and accuracy. Levels are run at gaging stations whenever differences in gage readings are unresolved, stations may have been damaged, or according to a pre-determined frequency. Engineer's levels, both optical levels and electronic digital levels, are commonly used for gaging-station levels. Collimation tests should be run at least once a week for any week that levels are run, and the absolute value of the collimation error cannot exceed 0.003 foot/100 feet (ft). An acceptable set of gaging-station levels consists of a minimum of two foresights, each from a different instrument height, taken on at least two independent reference marks, all reference points, all gages, and the water surface. The initial instrument height is determined from another independent reference mark, known as the origin, or base reference mark. The absolute value of the closure error of a leveling circuit must be less than or equal to ft, where n is the total number of instrument setups, and may not exceed |0.015| ft regardless of the number of instrument setups. Closure error for a leveling circuit is distributed by instrument setup and adjusted elevations are determined. Side shots in a level circuit are assessed by examining the differences between the adjusted first and second elevations for each objective point in the circuit. The absolute value of these differences must be less than or equal to 0.005 ft. Final elevations for objective points are determined by averaging the valid adjusted first and second elevations. If final elevations indicate that the reference gage is off by |0.015| ft or more, it must be reset.

Final environmental impact statement. Management of commercially generated radioactive waste. Volume 2. Appendices  

SciTech Connect

This EIS analyzes the significant environmental impacts that could occur if various technologies for management and disposal of high-level and transuranic wastes from commercial nuclear power reactors were to be developed and implemented. This EIS will serve as the environmental input for the decision on which technology, or technologies, will be emphasized in further research and development activities in the commercial waste management program. The action proposed in this EIS is to (1) adopt a national strategy to develop mined geologic repositories for disposal of commercially generated high-level and transuranic radioactive waste (while continuing to examine subseabed and very deep hole disposal as potential backup technologies) and (2) conduct a R and D program to develop such facilities and the necessary technology to ensure the safe long-term containment and isolation of these wastes. The Department has considered in this statement: development of conventionally mined deep geologic repositories for disposal of spent fuel from nuclear power reactors and/or radioactive fuel reprocessing wastes; balanced development of several alternative disposal methods; and no waste disposal action. This volume contains appendices of supplementary data on waste management systems, geologic disposal, radiological standards, radiation dose calculation models, related health effects, baseline ecology, socio-economic conditions, hazard indices, comparison of defense and commercial wastes, design considerations, and wastes from thorium-based fuel cycle alternatives.

Final LDRD report : advanced materials for next generation high-efficiency thermochemistry.  

SciTech Connect

Despite rapid progress, solar thermochemistry remains high risk; improvements in both active materials and reactor systems are needed. This claim is supported by studies conducted both prior to and as part of this project. Materials offer a particular large opportunity space as, until recently, very little effort apart from basic thermodynamic analysis was extended towards understanding this most fundamental component of a metal oxide thermochemical cycle. Without this knowledge, system design was hampered, but more importantly, advances in these crucial materials were rare and resulted more from intuition rather than detailed insight. As a result, only two basic families of potentially viable solid materials have been widely considered, each of which has significant challenges. Recent efforts towards applying an increased level of scientific rigor to the study of thermochemical materials have provided a much needed framework and insights toward developing the next generation of highly improved thermochemically active materials. The primary goal of this project was to apply this hard-won knowledge to rapidly advance the field of thermochemistry to produce a material within 2 years that is capable of yielding CO from CO2 at a 12.5 % reactor efficiency. Three principal approaches spanning a range of risk and potential rewards were pursued: modification of known materials, structuring known materials, and identifying/developing new materials for the application. A newly developed best-of-class material produces more fuel (9x more H2, 6x more CO) under milder conditions than the previous state of the art. Analyses of thermochemical reactor and system efficiencies and economics were performed and a new hybrid concept was reported. The larger case for solar fuels was also further refined and documented.

Preparation of the final Decommissioning Rule by the Nuclear Regulatory Commission (NRC) staff has been assisted by Pacific Northwest Laboratory (PNL) staff familiar with decommissioning matters. These efforts have included updating previous cost estimates developed during the series of studies of conceptually decommissioning reference licensed nuclear facilities for inclusion in the Final Generic Environmental Impact Statement (FGEIS) on decommissioning; documenting the cost updates; evaluating the cost and dose impacts of post-TMI-2 backfits on decommissioning; developing a revised scaling formula for estimating decommissioning costs for reactor plants different in size from the reference boiling water reactor (BWR) described in the earlier study; and defining a formula for adjusting current cost estimates to reflect future escalation in labor, materials, and waste disposal costs. This report presents the results of recent PNL studies to provide supporting information in three areas concerning decommissioning of the reference BWR: updating the previous cost estimates to January 1986 dollars; assessing the cost and dose impacts of post-TMI-2 backfits; and developing a scaling formula for plants different in size than the reference plant and an escalation formula for adjusting current cost estimates for future escalation.

The external induced environment generated by space station activity, or more specifically by gases, particles, and light background is discussed. These contaminant species must be controlled if sensitive systems, such as solar energy collectors or science experiments exposed to the external environment are to function properly. The requirements generally set limits on the level of gas species, matter deposited on surfaces and light background levels over various spectral regions. They also address environment monitoring and contamination controls during manufacturing. Limits on effluent release and system leakages are in turn derived from these requirements.

Space station ventilation study  

NASA Technical Reports Server (NTRS)

A ventilation system design and selection method which is applicable to any manned vehicle were developed. The method was used to generate design options for the NASA 33-foot diameter space station, all of which meet the ventilation system design requirements. System characteristics such as weight, volume, and power were normalized to dollar costs for each option. Total system costs for the various options ranged from a worst case $8 million to a group of four which were all approximately $2 million. A system design was then chosen from the $2 million group and is presented in detail. A ventilation system layout was designed for the MSFC space station mockup which provided comfortable, efficient ventilation of the mockup. A conditioned air distribution system design for the 14-foot diameter modular space station, using the same techniques, is also presented. The tradeoff study resulted in the selection of a system which costs $1.9 million, as compared to the alternate configuration which would have cost $2.6 million.

The role of synoptic-scale features and advection in prolonged warming and generation of different forms of precipitation at Dome Fuji station, Antarctica, following a prominent blocking event  

NASA Astrophysics Data System (ADS)

A blocking event over the East Antarctic ice sheet during June 1997 generated the highest surface air temperature (which increased from around -70C to around -30C) and pressure of that year at the Dome Fuji station (77.5S, 40E). Following the blocking event, the anomalously high air temperature (around -50C to -60C) and pressure were maintained at the surface for about 1 week. This study investigates how these warm conditions were maintained and documents the sequential occurrence of two forms of synoptic-scale high-pressure systems with conditions that produced precipitation by different processes in each case. In the first half of the warm period, a solitary high-pressure system (the Solitary High) formed over the Dome Fuji station and traveled west over East Antarctica after being cut off from the tip of the preceding blocking ridge. During this phase, tropospheric temperatures were higher, and surface-based temperature inversions were more intense than during the following period. While a dry-out developed in the troposphere below about 300 hPa, the precipitation of ice crystals in the surface-based temperature inversion layer was generated by deposition of moisture that had become trapped in the boundary layer after being transported onto the continent by the previous blocking ridge. This mechanism has not been previously reported elsewhere. During the second half of the warm period, a ridge of high pressure (the Transcontinental Ridge) traversed East Antarctica almost completely, and its western section was amplified by the merging of the Solitary High with a preceding quasi-stationary Rossby wave train propagating along the Southern Ocean. This ridge allowed an intrusion of warm, moist air from the Weddell Sea toward the station, which generated precipitation throughout the whole troposphere by orographic uplift once again, and ended the dry-out. This represents the typical mechanism of both moisture transportation and the generation of precipitation, and this mechanism was the same as that associated with the preceding blocking ridge.

APSTNG: Associated particle sealed-tube neutron generator studies for arms control. Final report on NN-20 Project ST220  

SciTech Connect

Argonne National Laboratory has performed research and development on the use of Associated Particle Sealed-Tube Neutron Generator (APSTNG) technology for treaty verification and non-proliferation applications, under funding from the DOE Office of Nonproliferation and National Security. Results indicate that this technology has significant potential for nondestructively detecting elemental compositions inside inspected objects or volumes. The final phase of this project was placement of an order for commercial procurement of an advanced sealed tube, with its high-voltage supply and control systems. Procurement specifications reflected lessons learned during the study. The APSTNG interrogates a volume with a continuous 14-MeV neutron flux. Each neutron is emitted coincident with an {open_quotes}associated{close_quotes} alpha-particle emitted in the opposite direction. Thus detection of an alpha-particle marks the emission of a neutron in a cone opposite to that defined by the alpha detector. Detection of a gamma ray coincident with the alpha indicates that the gamma was emitted from a neutron-induced reaction inside the neutron cone: the gamma spectra can be used to identify fissionable materials and many isotopes having an atomic number larger than that of boron. The differences in gamma-ray and alpha-particle detection times yield a coarse measurement of the distance along the cone axis from the APSTNG emitter to each region containing the identified nuclide. A position-sensitive alpha detector would permit construction of coarse three-dimensional images. The source and emission-detection systems can be located on the same side of the interrogated volume. The neutrons and gamma rays are highly penetrating. A relatively high signal-to-background ratio allows the use of a relatively small neutron source and conventional electronics.

Evaluation of interim and final waste forms for the newly generated liquid low-level waste flowsheet  

SciTech Connect

The purpose of this review is to evaluate the final forms that have been proposed for radioactive-containing solid wastes and to determine their application to the solid wastes that will result from the treatment of newly generated liquid low-level waste (NGLLLW) and Melton Valley Storage Tank (MVST) supernate at the Oak Ridge National Laboratory (ORNL). Since cesium and strontium are the predominant radionuclides in NGLLLW and MVST supernate, this review is focused on the stabilization and solidification of solid wastes containing these radionuclides in cement, glass, and polymeric materials-the principal waste forms that have been tested with these types of wastes. Several studies have shown that both cesium and strontium are leached by distilled water from solidified cement, although the leachabilities of cesium are generally higher than those of strontium under similar conditions. The situation is exacerbated by the presence of sulfates in the solution, as manifested by cracking of the grout. Additives such as bentonite, blast-furnace slag, fly ash, montmorillonite, pottery clay, silica, and zeolites generally decrease the cesium and strontium release rates. Longer cement curing times (>28 d) and high ionic strengths of the leachates, such as those that occur in seawater, also decrease the leach rates of these radionuclides. Lower cesium leach rates are observed from vitrified wastes than from grout waste forms. However, significant quantities of cesium are volatilized due to the elevated temperatures required to vitrify the waste. Hence, vitrification will generally require the use of cleanup systems for the off-gases to prevent their release into the atmosphere.

Draper Station Analysis Tool  

NASA Technical Reports Server (NTRS)

Draper Station Analysis Tool (DSAT) is a computer program, built on commercially available software, for simulating and analyzing complex dynamic systems. Heretofore used in designing and verifying guidance, navigation, and control systems of the International Space Station, DSAT has a modular architecture that lends itself to modification for application to spacecraft or terrestrial systems. DSAT consists of user-interface, data-structures, simulation-generation, analysis, plotting, documentation, and help components. DSAT automates the construction of simulations and the process of analysis. DSAT provides a graphical user interface (GUI), plus a Web-enabled interface, similar to the GUI, that enables a remotely located user to gain access to the full capabilities of DSAT via the Internet and Webbrowser software. Data structures are used to define the GUI, the Web-enabled interface, simulations, and analyses. Three data structures define the type of analysis to be performed: closed-loop simulation, frequency response, and/or stability margins. DSAT can be executed on almost any workstation, desktop, or laptop computer. DSAT provides better than an order of magnitude improvement in cost, schedule, and risk assessment for simulation based design and verification of complex dynamic systems.

Space Station Freedom as an engineering experiment station: An overview  

NASA Technical Reports Server (NTRS)

In this presentation, the premise that Space Station Freedom has great utility as an engineering experiment station will be explored. There are several modes in which it can be used for this purpose. The most obvious are space qualification, process development, in space satellite repair, and materials engineering. The range of engineering experiments which can be done at Space Station Freedom run the gamut from small process oriented experiments to full exploratory development models. A sampling of typical engineering experiments are discussed in this session. First and foremost, Space Station Freedom is an elaborate experiment itself, which, if properly instrumented, will provide engineering guidelines for even larger structures which must surely be built if humankind is truly 'outward bound.' Secondly, there is the test, evaluation and space qualification of advanced electric thruster concepts, advanced power technology and protective coatings which must of necessity be tested in the vacuum of space. The current approach to testing these technologies is to do exhaustive laboratory simulation followed by shuttle or unmanned flights. Third, the advanced development models of life support systems intended for future space stations, manned mars missions, and lunar colonies can be tested for operation in a low gravity environment. Fourth, it will be necessary to develop new protective coatings, establish construction techniques, evaluate new materials to be used in the upgrading and repair of Space Station Freedom. Finally, the industrial sector, if it is ever to build facilities for the production of commercial products, must have all the engineering aspects of the process evaluated in space prior to a commitment to such a facility.

Local control stations  

SciTech Connect

This paper describes research concerning the effects of human engineering design at local control stations (i.e., operator interfaces located outside the control room) on human performance and plant safety. The research considered both multifunction panels (e.g. remote shutdown panels) as well as single-function interfaces (e.g., valves, breakers, gauges, etc.). Changes in performance shaping factors associated with variations in human engineering at LCSs were estimated based on expert opinion. By means of a scaling procedure, these estimates were used to modify the human error probabilities in a PRA model, which was then employed to generate estimates of plant risk and scoping-level value/impact ratios for various human engineering upgrades. Recent documentation of human engineering deficiencies at single-function LCSs was also reviewed, and an assessment of the current status of LCSs with respect to human engineering was conducted.

Development of a variable-speed generator driven by an internal combustion engine. Final report, June 1989-December 1990  

SciTech Connect

The report describes the development of a variable-speed generator driven by a reciprocating engine. The operating speed range for the system is 1200 rpm to 3000 rpm. In that range the generator produces at its output 11 kW to 32 kW at high electrical efficiency. Less than 11 kW may be obtained by closing the throttle enough to produce the desired power level at 1200 rpm, but the more the throttle is closed the lower the electrical efficiency becomes. The engine-generator set uses a doubly-fed machine as the generator, a series-resonant converter to condition the power on the rotor windings, and a supervisory controller to execute the operating strategy and protection and diagnostics. It is a grid-connected system and can generate or consume reactive power on the stator windings of the generator. At synchronous speed the system is able to generate the same power as a fixed-speed system of the same rating. However, to reduce the output power it reduces the shaft speed instead of closing the throttle. The action maintains high electrical efficiency. The system is also able to operate above synchronous speed, which means it can produce more power than a fixed-speed system of the same rating.

The Activities and Importance of International Field Stations  

NSDL National Science Digital Library

Field stations worldwide are valuable resources for the discovery of natural phenomena, education and enlightenment of students, and training of the next generation of field scientists. Field stations face the pressures of human population expansion, habitat and biodiversity loss, and changing environmental conditions, and hence are sentinels of the state of our precarious Earth. We demonstrate the importance of field stations by describing developments supported by field stations and by examining recent literature. Eleven percent of papers published in Conservation Biology and 26% of those published in Ecology were supported in some way by a field station. We review data supplied by field stations over the last 20 years about stationsâ ecology, dominant discipline, personnel, and infrastructure. Communication among international field stations is difficult and could be improved by the formation of more regional networks. An international network would help elevate the recognition of the importance of field stations.

Photovoltaic central station step and touch potential considerations in grounding system design  

NASA Technical Reports Server (NTRS)

The probability of hazardous step and touch potentials is an important consideration in central station grounding system design. Steam turbine generating station grounding system design is based on accepted industry practices and there is extensive in-service experience with these grounding systems. A photovoltaic (PV) central station is a relatively new concept and there is limited experience with PV station grounding systems. The operation and physical configuration of a PV central station is very different from a steam electric station. A PV station bears some similarity to a substation and the PV station step and touch potentials might be addressed as they are in substation design. However, the PV central station is a generating station and it is appropriate to examine the effect that the differences and similarities of the two types of generating stations have on step and touch potential considerations.

Automatic Weather Station (AWS) Lidar  

NASA Technical Reports Server (NTRS)

An autonomous, low-power atmospheric lidar instrument is being developed at NASA Goddard Space Flight Center. This compact, portable lidar will operate continuously in a temperature controlled enclosure, charge its own batteries through a combination of a small rugged wind generator and solar panels, and transmit its data from remote locations to ground stations via satellite. A network of these instruments will be established by co-locating them at remote Automatic Weather Station (AWS) sites in Antarctica under the auspices of the National Science Foundation (NSF). The NSF Office of Polar Programs provides support to place the weather stations in remote areas of Antarctica in support of meteorological research and operations. The AWS meteorological data will directly benefit the analysis of the lidar data while a network of ground based atmospheric lidar will provide knowledge regarding the temporal evolution and spatial extent of Type la polar stratospheric clouds (PSC). These clouds play a crucial role in the annual austral springtime destruction of stratospheric ozone over Antarctica, i.e. the ozone hole. In addition, the lidar will monitor and record the general atmospheric conditions (transmission and backscatter) of the overlying atmosphere which will benefit the Geoscience Laser Altimeter System (GLAS). Prototype lidar instruments have been deployed to the Amundsen-Scott South Pole Station (1995-96, 2000) and to an Automated Geophysical Observatory site (AGO 1) in January 1999. We report on data acquired with these instruments, instrument performance, and anticipated performance of the AWS Lidar.

Space station molecular sieve development  

NASA Technical Reports Server (NTRS)

An essential function of a space environmental control system is the removal of carbon dioxide (CO2) from the atmosphere to control the partial pressure of this gas at levels lower than 3 mm Hg. The use of regenerable solid adsorbents for this purpose was demonstrated effectively during the Skylab mission. Earlier sorbent systems used zeolite molecular sieves. The carbon molecular sieve is a hydrophobic adsorbent with excellent potential for space station application. Although carbon molecular sieves were synthesized and investigated, these sieves were designed to simulate the sieving properties of 5A zeolite and for O2/N2 separation. This program was designed to develop hydrophobic carbon molecular sieves for CO2 removal from a space station crew environment. It is a first phase effort involved in sorbent material development and in demonstrating the utility of such a material for CO2 removal on space stations. The sieve must incorporate the following requirements: it must be hydrophobic; it must have high dynamic capacity for carbon dioxide at the low partial pressure of the space station atmosphere; and it must be chemiclly stable and will not generate contaminants.

Applications study of advanced power generation systems utilizing coal-derived fuels. Volume 1: executive summary. Final report  

SciTech Connect

The technology status of phosphoric acid and molten carbon fuel cells, combined gas and steam turbine cycles, and magnetohydrodynamic energy conversion systems was assessed and the power performance of these systems when operating with medium-Btu fuel gas whether delivered by pipeline to the power plant or in an integrated mode in which the coal gasification process and power system are closely coupled as an overall power plant was evaluated. Commercially available combined-cycle gas turbine systems can reach projected required performance levels for advanced systems using currently available technology. The phosphoric acid fuel cell appears to be the next most likely candidate for commercialization. On pipeline delivery, the systems efficiency ranges from 40.9% for the phosphoric acid fuel cell to 63% for the molten carbonate fuel cell system. The efficiencies of the integrated power plants vary from approximately 39 to 40% for the combined cycle to 46 to 47% for the molden carbonate fuel cell systems. Conventional coal-fired steam stations with flue-gas desulfurization have only 33 to 35% efficiency.

Some of the key results are highlighted. A novel process for generating ELF/ULF waves by using ionospheric heating was discovered, and its applicability to auroral geometry was examined. The process relies on modulated E-region heating and does not depend on the presence of ambient ionospheric currents.

Alternative strategies for space station financing  

NASA Technical Reports Server (NTRS)

The attributes of the proposed space station program are oriented toward research activities and technologies which generate long term benefits for mankind. Unless such technologies are deemed of national interest and thus are government funded, they must stand on their own in the market place. Therefore, the objectives of a United States space station should be based on commercial criteria; otherwise, such a project attracts no long term funding. There is encouraging evidence that some potential space station activities should generate revenues from shuttle related projects within the decade. Materials processing concepts as well as remote sensing indicate substantial potential. Futhermore, the economics and thus the commercial feasibility of such projects will be improved by the operating efficiencies available with an ongoing space station program.
