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.

Dubuque generation station, Dubuque, Iowa  

SciTech Connect

Alliant Energy's Dubuque generation station is a fine example of why small does not mean insignificant in the power generation industry. This winner of the EUCG best performer award in the small plant category shows that its operating excellence towers over that of many larger and much newer coal-fired power plants. The plant has three operating units with boilers originally designed for Illinois basin coal but now Powder River Basin coal makes up 75% of the coal consumed. The boilers can also burn natural gas. 4 photos.

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.

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.

Field testing of behavioral barriers for fish exclusion at cooling-water intake systems: Ontario Hydro Pickering Nuclear Generating Station: Final report  

SciTech Connect

A field sampling program was conducted during the spring--summer of 1985 and 1986 at a test facility located offshore of Ontario Hydro's Pickering Nuclear Generating Station (NGS) on Lake Ontario. The objective of the field program was to evaluate the effectiveness of selected behavioral barriers for fish exclusion at generating facilities located on large freshwater lakes or impoundments. Three commercially available devices (air bubble curtain, pneumatic gun, and underwater strobe lights) were tested alone and in combination to determine their effectiveness in reducing impingement. Sampling was conducted at two identical structures with the behavioral barrier devices installed on one of the structures and the other structure acting as a control. The effectiveness of the devices at excluding alewife (the dominant local species) was determined by comparing net catches covering 2-h test periods between the two structures. All of the behavioral barrier devices or combinations of devices tested exhibited effectiveness index values greater than 50%. The greatest deterrent capability was associated with the pneumatic gun; the least with the air bubble curtain. Device combinations that included the pneumatic gun were generally less effective than the pneumatic gun alone. The underwater strobe light was only marginally effective at excluding alewife. The air bubble curtain and underwater strobe light combination was more effective than each device separately, but the results were variable. 48 refs., 41 figs., 21 tabs.

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.

Next generation SAR demonstration on space station  

SciTech Connect

This paper describes the next generation synthetic aperture radar (SAR) that enables future low cost space-borne radar missions. In order to realize these missions, we propose to use an inflatable, membrane, microstrip antenna that is particularly suitable for low frequency science radar missions. In order to mitigate risks associated with this revolutionary technology, the space station demonstration will be very useful to test the long-term survivability of the proposed antenna. This experiment will demonstrate several critical technology challenges associated with space-inflatable technologies. Among these include space-rigidization of inflatable structures, controlled inflation deployment, flatness and uniform separation of thin-film membranes and RF performance of membrane microstrip antennas. This mission will also verify the in-space performance of lightweight, high performance advanced SAR electronics. Characteristics of this SAR instrument include a capability for high resolution polarimetric imaging. The mission will acquire high quality scientific data using this advanced SAR to demonstrate the utility of these advanced technologies. We will present an inflatable L-band SAR concept for commercial and science applications and a P-band design concept to validate the Biomass SAR mission concept. The ionospheric effects on P-band SAR images will also be examined using the acquired data.

Cameron Station remedial investigation: Final asbestos survey report. Final report  

SciTech Connect

Woodward-Clyde Federal Services (WCFS) conducted a comprehensive asbestos survey of the facilities at Cameron Station as part of its contract with the US Army Toxic and Hazardous Materials Agency (USATHAMA) to perform a remedial investigation and feasibility study (RI/FS) at the base. The purpose of the survey which was initiated August 23, 1990 in response to the Base Realignment And Closure Environmental Restoration Strategy (BRAC), was to identify friable and non-friable asbestos-containing material (ACM), provide options for abatement of asbestos, provide cost estimates for both abatement and operations and maintenance costs, and identifying actions requiring immediate action in Cameron Station`s 24 buildings. BRAC states that only friable asbestos which presents a threat to health and safety shall be removed; non-friable asbestos or friable asbestos which is encapsulated or in good repair shall be left in place and identified to the buyer per GSA agreement. The investigation followed protocols that met or exceeded the requirements of 40 CFR 763, the EPA regulations promulgated under the Asbestos Hazard Emergency Response Act (AHERA).

Space station automation and robotics study. Final report  

SciTech Connect

The methodology used in the study is to establish functional requirements for the operator-system-interface (OSI), establish the technologies needed to meet these requirements, and to forecast the availability of these technologies. The study looked at progressively more detailed Space Station functions, starting from general stationkeeping functions, down to proximity operations, and finally to the extra vehicular (EV) robot functions. The EV robot envisioned would be a free-flyer while in transit from one location to another in close proximity to the orbiting Space Station. The OSI would perform path planning, tracking and control, object recognition, fault detection and correction, and plan modifications in connection with EV robot operations. The implementation of the OSI implies the use of natural languages, voice recognition and synthesis, speech understanding, expert diagnostic and advisory knowledge systems, and machine learning.

Study of flywheel energy storage for space stations. Final Report  

SciTech Connect

The potential of flywheel systems for space stations using the Space Operations Center (SOC) as a point of reference is discussed. Comparisons with batteries and regenerative fuel cells are made. In the flywheel energy storage concept, energy is stored in the form of rotational kinetic energy using a spinning wheel. Energy is extracted from the flywheel using an attached electrical generator energy is provided to spin the flywheel by a motor, which operates during sunlight using solar array power. The motor and the generator may or may not be the same device. Flywheel energy storage systems have a very good potential for use in space stations. This system can be superior to alkaline secondary batteries and regenerable fuel cells in most of the areas that are important in spacecraft applications. Of special impotance relative to batteries, are high energy density (lighter weight), longer cycle and operating life, and high efficiency which minimizes the amount of orbital makeup fuel required. In addition, flywheel systems have a long shelf life, give a precise state of charge indication, have modest thermal control needs, are capable of multiple discharges per orbit, have simple ground handling needs, and have the potential for very high discharge rate. Major disadvantages are noted.

Attached algae of the Lake Erie shoreline near Nanticoke generating station

The distribution, species composition and standing crop of attached algae were surveyed in the splash zone along the shore of Lake Erie from 1971 to 1978 to determine the impact of construction and operation of the Nanticoke Generating Station, a coal-fired power plant. Station operation has had no apparent influence on the spatial distribution of attached algae in the lake stations. However, the discharge of heated condenser cooling water has resulted in an accelerated growth of attached algae in the immediate vicinity of the station early in the growing season, but the effect was not sustained after May. The species composition at sites near the generating station differed from control areas. Three years after the initial operation of the plant the generating station had a lower percent abundance of Cladophora and a higher percent abundance of weakly attached algal species such as Zygnema; this is perhaps attributable to the sheltered conditions in the discharge area of the generating station.

DESIGNING AN 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, 2001--September 30, 2001, Allegheny Energy Supply Co., LLC (Allegheny) continued construction of the Willow Island cofiring project, completed the installation of the fuel storage facility, the fuel receiving facility, and the processing building. All mechanical equipment has been installed and electrical construction has proceeded. During this time period significant short term testing of the Albright Generating Station cofiring facility was completed, and the 100-hour test was planned for early October. The testing demonstrated that cofiring at the Albright Generating Station could contribute to a ''4P Strategy''--reduction of SO{sub 2}, NO{sub x}, mercury, and greenhouse gas emissions. This report summarizes the activities associated with the Designer Opportunity Fuel program, and demonstrations at Willow Island and Albright Generating Stations. It details the construction activities at both sites along with the combustion modeling at the Willow Island site.

Approach of virtual observations generation of a multi-reference GPS station network  

NASA Astrophysics Data System (ADS)

The generation of virtual reference station observations to relay the corrections to the rover receiver for use with standard RTK software is one of important architectures of reference station networks RTK positioning. The approach of virtual observations generation based on a multi-reference GPS station network is presented in this paper. Ambiguities for the baselines in the reference network are determined firstly. The inter-reference-station differential spatially-correlated errors are estimated using highly accurate coordinates of the reference stations and resolved ambiguities. These spatially-correlated errors are interpolated among the network region as corrections. These network-generated corrections are used to correct the zero-differential observables of one reference station, which is usually the closest one to the rover (the so-called primary reference station). These corrected zero-differential observables, named virtual observations, are processed using conventional single reference station differential GPS algorithms. A test conducted using regional reference networks in Jiangsu(China) demonstrates the effectiveness of the approach to reduce the time to integer ambiguity resolution, and to increase the distance over which centimeter level accuracies can be achieved.

Economic and technical analysis of distributed utility benefits for hydrogen refueling stations. Final report  

SciTech Connect

This report presents the potential economic benefits of operating hydrogen refueling stations to accomplish two objectives: supply pressurized hydrogen for vehicles, and supply distributed utility generation, transmission and distribution peaking energy and capacity to the utility. The study determined under what circumstances using a hydrogen-fueled generator as a distributed utility generation source, co-located with the hydrogen refueling station components (electrolyzer and storage), would result in cost savings to the station owner, and hence lower hydrogen production costs. The systems studied include a refueling station (including such components as an electrolyzer, storage, hydrogen dispensers, and compressors) plus on-site hydrogen fueled electricity generation units (e.g., fuel cells or combustion engines). The operational strategy is to use off-peak electricity in the electrolyzer to fill hydrogen storage, and to dispatch the electricity generation about one hour per day to meet the utility`s local and system peaks. The utility was assumed to be willing to pay for such service up to its avoided generation, fuel, transmission and distribution costs.

Impact assessment of respirable suspended particulate matter from diesel generator sets used for pumping station.  

PubMed

Prediction of respirable suspended particulate matter impacts of diesel generator sets used for pumping station has been made using meteorological data, information on stack characteristics and emission rate, baseline ambient particulate matter and Industrial Source Complex Short Term (ISCST-3) model. It is observed that particulate matter emission from pumping station-S workplace diesel generator sets ranged from 2.4 to 436.5 mg Nm?³ and while at pumping station-C, it ranged from 23.2 to 186.5 mg Nm?³. The predicted and ambient respirable suspended particulate matter concentrations are below the national air quality standard for respirable suspended particulate matter in a mixed industrial area. Metals contents in respirable suspended particulate matter indicate the origin of crustal and mobile sources. Therefore, the impact of diesel generator sets used for pumping of crude oil on local air quality would be acceptable. PMID:20700577

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.

Modeling of a horizontal steam generator for the submerged nuclear power station concept  

SciTech Connect

A submerged nuclear power station has been proposed as an alternative power station with a relatively low environmental impact for use by both industrialized and developing countries. The station would be placed 10 m above the seabed at a depth of 30--100 m and a distance of 10--30 km from shore. The submerged nuclear power station would be manufactured and refueled in a central facility, thus gaining the economies of factoryfabrication and the flexibility of short-lead-time deployment. To minimize the size of the submerged hull, horizontal steam generators are proposed for the primary-to-secondary heat transfer, instead of the more traditional vertical steam generators. The horizontal steam generators for SNPS would be similar in design to the horizontal steam generators used in the N-Reactors except the tube orientation is horizontal (the tube's inlet and outlet connection points on the tubesheet are at the same elevation). Previous RELAP5 input decks for horizontal steam generators have been either very simplistic (Loviisa PWR) or used a vertical tube orientation (N-Reactor). This paper will present the development and testing of a RELAP5 horizontal steam generator model, complete with a simple secondary water level control system, that accounts for the dynamic flow conditions which exist inside horizontal steam generators.

Is central station generation becoming a white elephant

Cost increases encourage the development of alternative sources of energy, and some of the alternatives currently under development lend themselves to moving the generation location back to load centers. In addition, some alternative sources have short lead times and minimal environmental impact, and are being subsidized through income tax policy. Alternative sources of energy have the potential for beginning to affect the usefulness of electric-generating plants and their high-voltage transmission networks before the end of this century. If this comes about, the electric utility industry may find its position similar to that of the telephone industry - with obsolete facilities not fully depreciated. The scenario discussed here would not come about all at once and may not come about at all. But it is the authors opinion that the chances are greater than fifty-fifty that it or something similar will affect the usefulness of bulk power supply systems sometime during the lifetime of generating units installed during the past ten years.

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.

Staff Draft Report. Comparative Cost of California Central Station Electricity Generation Technologies.  

SciTech Connect

This Energy Commission staff draft report presents preliminary levelized cost estimates for several generic central-station electricity generation technologies. California has traditionally adopted energy policies that balance the goals of supporting economic development, improving environmental quality and promoting resource diversity. In order to be effective, such policies must be based on comprehensive and timely gathering of information. With this goal in mind, the purpose of the report is to provide comparative levelized cost estimates for a set of renewable (e.g., solar) and nonrenewable (e.g., natural gas-fired) central-station electricity generation resources, based on each technology's operation and capital cost. Decision-makers and others can use this information to compare the generic cost to build specific technology. These costs are not site specific. If a developer builds a specific power plant at a specific location, the cost of siting that plant at that specific location must be considered. The Energy Commission staff also identifies the type of fuel used by each technology and a description of the manner in which the technology operates in the generation system. The target audiences of this report are both policy-makers and anyone wishing to understand some of the fundamental attributes that are generally considered when evaluating the cost of building and operating different electricity generation technology resources. These costs do not reflect the total cost to consumers of adding these technologies to a resources portfolio. These technology characterizations do not capture all of the system, environmental or other relevant attributes that would typically be needed by a portfolio manager to conduct a comprehensive ''comparative value analysis''. A portfolio analysis will vary depending on the particular criteria and measurement goals of each study. For example, some form of firm capacity is typically needed with wind generation to support system reliability. [DJE-2005

NGV stations based on mobile tube trailers: An economic analysis. Final report, June 1994-January 1995  

SciTech Connect

This report assesses the technical and economic issues associated with the use of mobile tube trailers for Natural Gas Vehicle (NGV) refueling stations. Specifically, this report examines the mobile tube trailer concept developed by Pacific Cryongenics, Inc. and Pacific Gas and Electric. Mobile tube trailers are filled with compressed natural gas (CNG) at an underutilized compressor station and transported to satellite station locations. NGVs are filled at the satellite stations usig compressed gas from the tube trailer. Results of the economic analysis show that, under various operating conditions, the mobile tube trailer concept provides a cost effective alternative to NGV refueling stations with permanent compressors. In addition, the tube trailers were found to provide a substantial load for undertutilized compressor stations, resulting in reduced CNG costs at existing stations.

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.

Advanced planar array development for space station. Final report, 1 June 1985-1 June 1987  

SciTech Connect

The results of the Advanced Planar Array Development for the Space Station contract are presented. The original objectives of the contract were: (1) to develop a process for manufacturing superstrate assemblies, (2) to demonstrate superstrate technology through fabrication and test, (3) to develop and analyze a preliminary solar array wing design, and (4) to fabricate a wing segment based on wing design. The primary tasks completed were designing test modules, fabricating, and testing them. LMSC performed three tasks which included thermal cycle testing for 2000 thermal cycles, thermal balance testing at the Boeing Environmental Test Lab in Kent, Washington, and acceptance testing a 15 ft x 50 in panel segment for 100 thermal cycles. The surperstrate modules performed well during both thermal cycle testing and thermal balance testing. The successful completion of these tests demonstrate the technical feasibility of a solar array power system utilizing superstrate technology. This final report describes the major elements of this contract including the manufacturing process used to fabricate modules, the tests performed, and the results and conclusions of the tests.

Defective-fuel analysis for the Point Lepreau Nuclear Generating Station  

SciTech Connect

From January 24, 1991, to February 19, 1992, increased radiation levels in the primary heat transport system (PHTS) were recorded by the gaseous fission product monitoring system at the Point Lepreau nuclear generating station. The fission product activity was attributed to cladding defects that had resulted from sheath hydriding due to an excess of hydrogen in the CANLUB coating of several batches of fuel. A model of fission product release from defective fuel under normal operating conditions has previously been validated with a series of experiments conducted in the X-2 loop at Chalk River Laboratories (CRL) and has become the basis of an expert system. This paper describes the application of the model to the analysis of fission product activity at the Point Lepreau reactor.

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.

Characterization of Navajo Generating Station emissions measured during the June-July 1979 vistta field program  

NASA Astrophysics Data System (ADS)

The Salt River Project, joint owner and operating agent for the Navajo Generating Station, participated in the jointly sponsored EPA-SRP June-July 1979 VISTTA Field Study. As part of this broad and intensive study, Salt River Project conducted an emissions measurements program at this power plant. This paper presents a brief description of the measurement techniques used and a summary of results. The program included measurements for paniculate and gaseous, sulfur dioxide and oxides of nitrogen, emissions and the determination of particle size distributions. The particulate and gaseous measurements were conducted in accordance with EPA Reference Methods 1-7. Particle size distributions were determined by a combination of techniques. Cascade impactors were used to collect data in the coarse panicle size range, 0.15 to 10 ?m. Data in the fine particle range, 0.4-2.0 ?m, and ultrafine particle range, 0.01-0.3 ?m, were acquired by optical particle counter and electrical aerosol analyzer techniques, respectively. Size segregated particulate samples, 0.4-5.0 ?m, were collected by a five stage series cyclone for subsequent chemical analysis. The elemental compositions of the cyclone samples were determined by neutron activation and wave length dispersive X-ray fluorescence. Station operating status (unit load, coal burn rate, etc.), precipitator performance and equipment problems were monitored and recorded. Coal samples were collected and analyzed for chemical compositions. The particle size distribution results indicated that the Unit 3 stack emissions were bimodal and that each distribution could be considered to be log normal. The stack measurements showed that there were significant variations in paniculate mass emissions between tests and between units. The SO 2 and NO x results were typical of emissions expected for normal operating conditions. Thirty-one elements were found in the cyclone samples by the elemental analyses.

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).

Radionuclides in sediments collected downstream from the Rancho Seco Nuclear Power Generating Station  

SciTech Connect

Amounts of radionuclides discharged since 1981 with liquid effluents from the Rancho Seco Nuclear Power Generating Station contained in downstream sediments were determined. Of the total /sup 137/Cs released since 1981, only 20% was found associated with bottom sediments sampled to a distance of 26 km from the plant. It is estimated that most of the unaccounted for /sup 137/Cs (40 to 60%) was transferred to land during the irrigation seasons. Soil samples from irrigated land contain /sup 137/Cs but no estimate of the land inventory has been made to date. Larger fractions of the particle reactive radionuclides, such as /sup 60/Co, /sup 54/Mn and /sup 110m/Ag, were found in the sediment deposits and the highest concentrations of these radionuclides were found in the on-site retention basins. Concentrations of /sup 137/Cs in sediment samples from the creek near the plant were extremely variable even over small spatial distances. However by averaging the inventories in sediments near the plant and comparing these with the downstream levels, a reasonable exponential regression equation (r/sup 2/ = 0.88) was developed to relate the 1984 inventories of /sup 137/Cs in the top 12 cm of bottom sediment with downstream distance. The change in the /sup 137/Cs sediment inventories with distance parallels the downstream change found for /sup 137/Cs concentrations in fish. Concentrations in non-migratory fresh water fish from any downstream location may be estimated from the creek sediment concentrations.

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.

Aging management program of the reactor building concrete at Point Lepreau Generating Station  

NASA Astrophysics Data System (ADS)

In order for New Brunswick Power Nuclear (NBPN) to control the risks of degradation of the concrete reactor building at the Point Lepreau Generating Station (PLGS) the development of an aging management plan (AMP) was initiated. The intention of this plan was to determine the requirements for specific structural components of concrete of the reactor building that require regular inspection and maintenance to ensure the safe and reliable operation of the plant. The document is currently in draft form and presents an integrated methodology for the application of an AMP for the concrete of the reactor building. The current AMP addresses the reactor building structure and various components, such as joint sealant and liners that are integral to the structure. It does not include internal components housed within the structure. This paper provides background information regarding the document developed and the strategy developed to manage potential degradation of the concrete of the reactor building, as well as specific programs and preventive and corrective maintenance activities initiated.

Aerial radiological survey of the Salem Nuclear Generating Station and surrounding area, Salem, New Jersey  

SciTech Connect

An aerial radiological survey was performed from 24 July through 1 August 1980 over a 244-square-kilometer (95-square-mile) area centered on the Salem Nuclear Generating Station near Salem, New Jersey. All gamma ray data were collected by flying lines oriented north-south and spaced 152 meters (500 feet) apart, at an altitude of 91 meters (300 feet) above the ground. Processed data showed that all gamma rays detected within the survey area were those expected from naturally occurring terrestrial background emitters except directly over the site, where spectral analysis revealed the presence of /sup 60/Co. Count rates obtained from the aerial platform were converted to exposure rates at 1 meter above the ground and are presented in the form of an exposure rate contour map. The resulting exposure rates varied between 5 and 55 microroentgens per hour (..mu..R/h). The river-shore areas ranged from 5 to 7 ..mu..R/h, inland areas showed 7 to 12 ..mu..R/h, and the site had a maximum exposure rate of 55 ..mu..R/h. These values include an estimated cosmic ray contribution of 4 ..mu..R/h. The exposure rates obtained from soil samples taken within the survey area displayed good agreement with the aerial data.

The generation of simple compliance boundaries for mobile communication base station antennas using formulae for SAR estimation.  

PubMed

In this paper, a procedure is proposed for generating simple and practical compliance boundaries for mobile communication base station antennas. The procedure is based on a set of formulae for estimating the specific absorption rate (SAR) in certain directions around a class of common base station antennas. The formulae, given for both whole-body and localized SAR, require as input the frequency, the transmitted power and knowledge of antenna-related parameters such as dimensions, directivity and half-power beamwidths. With knowledge of the SAR in three key directions it is demonstrated how simple and practical compliance boundaries can be generated outside of which the exposure levels do not exceed certain limit values. The conservativeness of the proposed procedure is discussed based on results from numerical radio frequency (RF) exposure simulations with human body phantoms from the recently developed Virtual Family.

Engineering evaluation of magma cooling-tower demonstration at Nevada Power Company's Sunrise Station. Final report  

SciTech Connect

The Magma Cooling Tower (MCT) process utilizes a falling film heat exchanger integrated into an induced draft cooling tower to evaporate wastewater. A hot water source such as return cooling water (90/sup 0/F to 110/sup 0/F) provides the energy for evaporation. Water quality control is maintained by removing potential scaling constituents to make concentration of the wastewater possible without scaling heat transfer surfaces. A pilot-scale demonstration test of the MCT process was performed from March 1979 through June 1979 at Nevada Power Company's Sunrise Station in Las Vegas, Nevada. The pilot unit extracted heat from the powerplant cooling system to evaporate cooling tower blowdown. Two water quality control methods were employed: makeup/sidestream softening and fluidized bed crystallization. The 11-week softening mode test was successful. The unit operated without biofouling or scaling at 100,000 ppM TDS levels under a wide range of operating conditions. Successful operation was not demonstrated in the 10-day crystallization mode test; calcium sulfate (CaSO/sub 4/) scaling occurred on the last day of the test at a maximum brine concentration of less than 40,000 ppM. An economic and technical comparison with other zero-discharge technologies showed that, for application at Sunrise, the MCT process had competitive capital, operating, and levelized annual costs. No major technical problems were encountered that would preclude the commercial application of a properly designed MCT unit operating in the softening mode.

Theory and economics of by-generation of electricity at city gate stations using a gas expander turbine  

SciTech Connect

The transmission pressure of pipeline gas entering a city-gate station offers an untapped energy source that gas-distribution companies can easily use to produce low-cost electricity. The high-pressure inlet gas can be heated, then isentropically expanded through a turbine that powers a generator and simultaneously reduces the gas pressure and temperature. The gas turboexpander behaves like a pinwheel in the line as the gas flow creates the rotary motion that drives the generator. The pressure and temperature differential that occurs across the inlet and outlet of the device can be held constant, functioning similarly to a standard regulator. The gas exiting the turbine is thus available at entry conditions for the gas-distribution system, while the electricity can be either used onsite or (in the case of a combination utility) fed into the network for electrical baseloading.

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

NASA Astrophysics Data System (ADS)

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.

Application of reliability-centered maintenance to the auxiliary feedwater system at San Onofre Nuclear Generating Station  

SciTech Connect

Reliability-centered maintenance (RCM) is a systematic methodology for defining applicable and effective preventive maintenance (PM) tasks. In 1984, the Electric Power Research Institute (EPRI) studied the air transport industry's RCM program as a candidate for technology transfer to the nuclear power industry. EPRI initiated two RCM pilot projects that directly utilized the RCM methodology developed by the aviation industry. The first RCM application was to the component cooling water systems of Florida Power and Light's Turkey Point Units 3 and 4. The second application was to the main feedwater system at Duke Power's McGuire Station. The results of these studies clearly indicate the benefits of the system-oriented RCM approach, and many areas for cost-effective improvements to PM programs were identified. After the completion of these two pilot studies, Southern California Edison and EPRI initiated an application of RCM to the auxiliary feedwater (AFW) system at the San Onofre Nuclear Generating Station, Unit 2. In contrast to the previous EPRI-sponsored applications to normally operating systems, the AFW system is a standby safety system. The study results demonstrate the usefulness of extending the RCM methodology to standby safety systems. The specific results show promise of reducing the PM costs for the AFW system at San Onofre while maintaining highly reliable system performance. The recommendations from this study are currently being considered for implementation by the plant maintenance staff.

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.

Operating experience with a wood fueled downdraft gasifier at the Highgrove generating station  

SciTech Connect

This paper describes the development effort to date by Southern California Edison Company to help alleviate the waste disposal problem and provide a supplemental fuel for existing generating units. The gasifier being demonstrated was originally scaled up from a small unit sponsored by the California Energy Commission to a size expected to be the largest commercially feasible for a single downdraft unit. Comprehensive air quality emissions sampling including particulate, PAH, NO/sub chi/, HC, SO/sub chi/, and standard combustion constituents was conducted on the boiler stack (co-firing) and the flare (100% wood gas). Both cases demonstrated results as low or lower than combustion natural gas alone. Recent studies indicate a potential wood waste feedstock availability within the service territory of nearly two million tons per year. This reserve could provide an alternate fuel to oil or natural gas for two hundred MW of generation while reducing the waste 95% into a non-toxic char which can be landfilled or recycled. Plans are underway to demonstrate a 50 X 10/sup 6/ Btu/hr fluid bed gasifier at Highgrove in the future which will be to operated on refuse.

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.

Unalaska geothermal exploration project. Electrical power generation analysis. Final report  

SciTech Connect

The objective of this study was to determine the most cost-effective power cycle for utilizing the Makushin Volcano geothermal resource to generate electricity for the towns of Unalaska and Dutch Harbor. It is anticipated that the geothermal power plant would be intertied with a planned conventional power plant consisting of four 2.5 MW diesel-generators whose commercial operation is due to begin in 1987. Upon its completion in late 1988, the geothermal power plant would primarily fulfill base-load electrical power demand while the diesel-generators would provide peak-load electrical power and emergency power at times when the geothermal power plant would be partially or completely unavailable. This study compares the technical, environmental, and economic adequacy of five state-of-the-art geothermal power conversion processes. Options considered are single- and double-flash steam cycles, binary cycle, hybrid cycle, and total flow cycle.

Spaceflight effects on consecutive generations of peas grown onboard the Russian segment of the International Space Station  

NASA Astrophysics Data System (ADS)

In the period from March 2003 to April 2005 we fulfilled five experimental cultivations of genetically marked dwarf pea species in greenhouse Lada installed in the Russian segment (RS) of the International Space Station (ISS). The purpose of this series of experiments was to make morphologic and genetic analysis of pea plants grown in successive generations. According to our results, pea growth and development over the full cycle of ontogenesis (from seed to seed) taking place in space greenhouse Lada were not different as compared with the ground control plants. In addition, four successive pea crops gathered in space flight did not loose their reproductive functions and formed viable seeds. Genetic analysis of the plants grown from the “space” and “ground” seeds produced by the first to fourth successive crops was performed using the methods of chromosomal aberrations count and Random Amplified Polymorphic DNA (molecular method). No genetic polymorphism was found either in the experimental or control crops. This can serve as a sound argument for the supposition that the genetic apparatus of plants is not impacted by exposure of several successive generations to the conditions of space flight.

Aerial radiological survey of the Palo Verde Nuclear Generating Station and surrounding area, Wintersburg, Arizona. Date of survey: November 1982  

SciTech Connect

An aerial survey of terrestrial gamma radiation was performed during the period 4 November through 15 November 1982 over a 16-kilometer by 16-kilometer (10-mile by 10-mile) area approximately centered on the Palo Verde Nuclear Generating Station near Wintersburg, Arizona. Gamma radiation spectral data were collected while flying a helicopter over a regular pattern of parallel lines spaced 150 meters (500 feet) apart at an altitude of 90 meters (300 feet). All radiation measurements taken at the nominal flight altitude were corrected for altitude variations, cosmic radiation, and helicopter background to generate exposure rates from terrestrial sources extrapolated to 1 meter above ground level. The data are presented as isoradiation contour maps. The average terrestrial radiation levels fall between 8 and 14 microrentgens per hour (..mu..R/h). All gamma radiation detected within the survey area was associated with naturally occurring radionuclides. Direct ground-based measurements at 1 meter height were also taken at four scattered sites within the survey area. These values agree with the contour intervals determined from the aerial measurements and differ from the mean value of adjacent contours by no more than 10%. 6 references, 5 figures, 2 tables.

Use of generator produced neutrons in coal analysis. Final report  

SciTech Connect

A 14 MeV neutron generator is satisfactory for making capture gamma-ray analysis in a borehole in rocks for a limited number of elements. In coal, a thermal-capture gamma-ray spectrum will yield data for a relatively larger number of elements. However, by the time 14 MeV neutrons are reduced to thermal energies and absorbed by the target elements the neutrons are a considerable distance from the neutron source and the detector. Consequently, the activated coal sample is dispersed and a long way from the detector, and results in a reduced sensitivity. If the neutron generator source emitted 2.5 MeV neutrons by a (D,D) reaction, the neutrons would be thermalized close to the detector. In this case, the sensitivity of the neutron activation method would be substantially enhanced. To produce a borehole generator which would produce 2.5 MeV neutrons, we started with 14 MeV generator using a tube-transformer assembly (TTA) as developed by the Sandia Corporation. A similar TTA was constructed using a deuterium rather than a tritium loaded target. The new TTA did not respond adequately with the exiting electronics. In the course of this investigation, a fast-response high-energy neutron detector using the {sup 16}O(n,p){sup 17}N reaction was developed which worked quite well and was a great help in adjusting the electronic parameters of the 14 MeV neutron generator. As the flux rate of the 2.5 MeV neutron generator was inadequate for activation analysis of coal, Cf-252 was substituted in order to obtain comparable spectra using 14 and 2.2 MeV neutrons. Using a specially constructed coal irradiation facility with a central borehole, experiments were made using neutrons of both energies and comparable fluxes. It is clear from the results that lower energy neutrons yield spectra which are more useful for coal analysis.

Use of a combined personal computer and Rock-Eval in an integrated petroleum evaluation work station to estimate volumes of hydrocarbons generated and migrated in sedimentary basins  

SciTech Connect

A petroleum evaluation work station consisting in a modified Rock-Eval apparatus connected to an IBM personal computer has been designed at Institut Francais du petrole to estimate the amount of hydrocarbon generated and migrated in sedimentary basins. The work-station is provided with specific software for Rock-Eval data analysis, quick determination of kinetic parameters (Optim model), and quantitative hydrocarbon generation (Matoil model). Along with the classical Rock-Eval parameters (S{sub 0}, S{sub 1}, S{sub 2}, TOC, and T{sub max}), new parameters concerning the source rocks, such as the transformation efficiency ratio (TER), the migration efficiency ration (MER), and the initial generation capacity (IGC), are defined. These new parameters combined with geological data give access to a rapid volumetric estimation (in 10{sup 6}MT/km{sup 2}) of hydrocarbon generation and migration in the studied area. These data can be displayed on different specific maps for rapid visualization. This work station has been successfully used in the Paris and Aquitaine basins, making possible a better assessment of their petroleum potential. The petroleum evaluation work station appears to be a very valuable tool that can be used in the different phases of exploration in a sedimentary basin.

Evaluation of station blackout accidents at nuclear power plants: Technical findings related to unresolved safety issue A-44: Final report  

SciTech Connect

''Station Blackout,'' which is the complete loss of alternating current (AC) electrical power in a nuclear power plant, has been designated as Unresolved Safety Issue A-44. Because many safety systems required for reactor core decay heat removal and containment heat removal depend on AC power, the consequences of a station blackout could be severe. This report documents the findings of technical studies performed as part of the program to resolve this issue. The important factors analyzed include: the fequency of loss of offsite power; the probability that emergency or onsite AC power supplies would be unavailable; the capability and reliability of decay heat removal systems independent of AC power; and the likelihood that offsite power would be restored before systems that cannot operate for extended periods without AC power fail, thus resulting in core damage. This report also addresses effects of different designs, locations, and operational features on the estimated frequency of core damage resulting from station blackout events.

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.

Power-flattening techniques for radioisotopic thermoelectric generators. Final report  

SciTech Connect

The objective of this program was to investigation of a novel means of reducing the potential ecologic hazards that may be associated with radiosotopic thermoelectric generators (RTG's). A number of short-lived isotopes have lower toxicities and are more ecologically acceptable than the Plutonium 238 used at present. In addition, the shorter half lives significantly reduce the time period during which isotope encapsulation must be assured (approximately 10 half lives). The technical approach involves the use of a gas-controlled heat pipe to maintain a nearly constant heat input to the thermoelectric converter in spite of the decay profile of a short-lived isotopic heat source. Excess thermal power available early in life, is automatically shorted around the thermoelectric module by way of the heat pipe. A development model of a gas-controlled heat pipe capable of performing the required task was constructed and tested during this program.

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.

Test results obtained during 1980-1981 at the Zvenigorod station are presented for the Intercosmos laser rangefinder which was modified in various ways: e.g., optical components of the laser were replaced, and the mechanical Q-switch of the laser resonator was replaced by a phototropic Q-switch. Improved reliability was noted, and the ranging accuracy was increased by 1.5-2 times. It is concluded that the Zvenigorod tests indicate that the first-generation Intercosmos laser rangefinder can be effectively modernized at other Intercosmos tracking stations.

Gas generation from Hanford grout samples. Final report  

SciTech Connect

The radiolytic yields of H{sub 2}, N{sub 2}, O{sub 2}, N{sub 2}O, and CO from two batches of WHC-supplied samples of grouted simulated waste have been {gamma} irradiated at several dose rates (0.025, 0.63 and 130 krad/h for H{sub 2} and 130 krad/h for all other gases). In one batch, the liquid waste simulant that was added to the grout included the original components that were added to Tank 102-AP (labeled ``virgin``waste.) The second batch included a similar liquid waste simulant that was preirradiated to 35 Mrad prior to incorporation into the grout. It is believed that the preirradiated samples more closely represent radioactive waste that was stored in the tank for several years. The lowest dose rate corresponds approximately to that expected in the grout; with the high dose rate, doses equivalent to about 85 years storage in grout vaults were achieved. Most of the results on the batch of virgin samples have been reported recently (Report ANL 93/42). Here we report the results from the batch of preirradiated grout samples and compare the results from the two batches. The radiolytic yields of H{sub 2} and N{sub 2} are lower in the preirradiated than in the virgin grout. On the other hand G(O{sub 2}) is higher in the preirradiated samples: 0.078 vs. 0.026. The yield of nitrous oxide is essentially the same, G(N{sub 2}O) =0.010, in both. The yields measured from both batches are significantly higher than previously reported values. At 90{degrees}C similar amounts of H{sub 2} were generated thermally from both batches of grout, whereas the total amounts of N{sub 2} and N{sub 2}O were larger for the preirradiated than for the virgin grout samples. At lower temperatures the rate of generation was hardly measurable. Mass spectrometric analysis suggests that NO is thermally (but not radiolytically) released from the grout samples.

The objective of this study was to define and quantify cost reductions in the Martin Marietta Denver Aerospace Second Generation Heliostat resulting from design and cost optimization. These cost reductions were based on optimizing the heliostat performance vs. cost and engineering design, and reviewing the design specification in selected technological areas with a goal of removing nonrealistic requirements and eliminating or minimizing overdesign. Specific technological areas investigated were: (1) designing the heliostat for survival strength rather than stiffness and reducing the operational wind requirements as dictated by this design approach; (2) reducing the pointing accuracy and/or beam quality required for some fraction or all of the heliostat field; (3) modifying the operational temperature range; (4) relaxing the rate at which the heliostat must move in the slew mode; (5) using alternate beam safety strategies; (6) analyzing actual wind data for selected sites in the southwest United States vs. the heliostat design specification survival wind requirements; (7) estimating heliostat damage for winds in excess of the design specification over a 30 year period; (8) evaluating the impact of designing the heliostat for higher wind loads; and (9) investigating the applicability to heliostat design of the standard engineering practices for designing buildings.

Biological potential of methane generation from poultry wastes. Final report  

SciTech Connect

Anaerobic digestion of animal waste is an attractive process because it degrades organic matter for pollution control and simultaneously produces methane gas for an alternate energy source. The biological potentials of methane generation from the two major kinds of poultry wastes, the litter of broiler chickens and the manure of laying hens have been systematically investigated. Using these wastes to prepare media for bacterial growth, thermophilic anaerobic cultures were initiated by inoculations of bacteria from different natural environments. After a period of acclimation, they were then challenged with various combinations of operational variables such as retention times, volatile solid concentrations, temperatures, and pH values. The most efficient culture and conditions were selected based on the highest gas rate. The results have demonstrated that the broiler litter is a substrate of very low potential. This seems due to the high content of wood shavings resistant to bacterial degradation. On the other hand, the layer manure is a high-potential substrate, which supported both a high methane rate (3.5 1/1/day) and a high methane yield (250 1/kg VS) under the selected conditions. Compared with other types of animal wastes, the manure of laying hens is one of the best substrates for methane production. Based on the data obtained in the laboratory, an anaerobic digester is under construction on the University research farm. A large digester will help answer other questions such as energy balance, economic evaluation and engineering design.

HYDROGEN GENERATION FROM ELECTROLYSIS - REVISED FINAL TECHNICAL REPORT  

SciTech Connect

DOE GO13028-0001 DESCRIPTION/ABSTRACT This report is a summary of the work performed by Teledyne Energy Systems to understand high pressure electrolysis mechanisms, investigate and address safety concerns related to high pressure electrolysis, develop methods to test components and systems of a high pressure electrolyzer, and produce design specifications for a low cost high pressure electrolysis system using lessons learned throughout the project. Included in this report are data on separator materials, electrode materials, structural cell design, and dissolved gas tests. Also included are the results of trade studies for active area, component design analysis, high pressure hydrogen/oxygen reactions, and control systems design. Several key pieces of a high pressure electrolysis system were investigated in this project and the results will be useful in further attempts at high pressure and/or low cost hydrogen generator projects. An important portion of the testing and research performed in this study are the safety issues that are present in a high pressure electrolyzer system and that they can not easily be simplified to a level where units can be manufactured at the cost goals specified, or operated by other than trained personnel in a well safeguarded environment. The two key objectives of the program were to develop a system to supply hydrogen at a rate of at least 10,000 scf/day at a pressure of 5000psi, and to meet cost goals of $600/ kW in production quantities of 10,000/year. On these two points TESI was not successful. The project was halted due to concerns over safety of high pressure gas electrolysis and the associated costs of a system which reduced the safety concerns.

The effects of scrubber installation at the Navajo Generating Station on particulate sulfur and visibility levels in the Grand Canyon.  

PubMed

Grand Canyon National Park (GCNP) is a mandatory Class I federal area that is afforded visibility protection under the Federal Clean Air Act. In this paper, we have examined the effects on visibility and particulate sulfur (Sp) at GCNP as a result of reducing sulfur dioxide (SO2) emissions by 90% from the Navajo Generating Station (NGS). Scrubbers were retrofitted to each of the three units at NGS during 1997, 1998, and 1999. The Inter-agency Monitoring of Protected Visual Environments aerosol network database affords us an opportunity to examine trends in Sp and extinction both prescrubber and postscrubber. The NGS impacts GCNP primarily during the winter (December to February). During winter, at times, there are fogs, stratus, and high-relative humidity in the Grand Canyon. When the NGS plume interacts with these fogs and stratus, rapid conversion of SO2 to Sp can occur. A variety of analytical techniques were used, including cumulative frequency plots of Sp and extinction, and chemical mass balance and tracer source apportionment analysis. We also deployed P value statistical analysis of "extreme" Sp values. Before scrubbers were installed, values of Sp approaching 2 microg/m3 were occasionally observed. Because scrubbers have been installed, high levels of Sp have been markedly reduced. Statistical P value analysis suggests that these reductions were significant. Furthermore, we have also observed that Sp has been reduced throughout the cumulative frequency curve during winter by approximately 33% since scrubbers were installed. By contrast, during summer when the NGS impact on the Canyon is minimal, there has been only a relatively small decrease in Sp. PMID:16350365

On-line monitoring of secondary-cycle chemistry with morpholine at the Beaver Valley Power Station: Final report  

SciTech Connect

Beaver Valley is the only PWR with vertical steam generators in the United States which has used morpholine in the all-volatile chemistry control program for its entire operating history. Morpholine is very similar to proposed alternatives to ammonia. Hence, a careful study of its benefits and side effects may provide an indication of the value of additives similar to, but superior to, morpholine. On-line chromatography was used to characterize morpholine, ammonia, organic acids, chloride, fluoride, and sulfate levels at Beaver Valley during operation with different morpholine feed rates. This study verified the feasibility of using on-line ion chromatography to monitor secondary cycle pH control agents, organic acids, and ionic impurities. Morpholine usage will elevate steam generator blowdown cation conductivity by approximately 0.1 to 0.15 ..mu..S/cm as a result of acetic and formic acids. However, organic acid levels do not increase in proportion to morpholine levels, suggesting a threshold reaction that is satisfied at low (e.g., 0.2 ppM) morpholine levels.

High availability interlocks and controls are required for the ILC (International Linear Collider) L-Band high power RF stations. A new F3 (Fast Fault Finder) VME module has been developed to process both fast and slow interlocks using FPGA logic to detect the interlock trip excursions. This combination eliminates the need for separate PLC (Programmable Logic Controller) control of slow interlocks. Modules are chained together to accommodate as many inputs as needed. In the next phase of development the F3's will be ported to the new industry standard ATCA (Advanced Telecom Computing Architecture) crate (shelf) via a specially designed VME adapter module with IPMI (Intelligent Platform Management Interface). The goal is to demonstrate auto-failover and hot-swap for future partially redundant systems.

Multi-station probing of thunderstorm-generated D-layer fluctuations by using time-domain lightning waveforms  

NASA Astrophysics Data System (ADS)

This study uses multi-station time-domain very-low and low-frequency (VLF/LF) lightning waveforms detected from a range of several hundred kilometers to probe fluctuations in D-layer ionospheric height and peak reflection ratio in three regions near a large thunderstorm on the night of 17 June 2005. These measurements show propagation of the fluctuations away from the thunderstorm in addition to a background eastward-propagating fluctuation over the entire region. Measured speeds of propagation range from ?45 m/s to ?85 m/s, consistent with horizontal propagation speeds of atmospheric gravity waves. The fluctuation propagation is seen in both the ionospheric height measurement and the peak reflection ratio measurement with similar periods and speeds. Ionospheric height perturbations in the measured regions can be as large as 6 km from average, and perturbations in peak reflection ratio can be as large at 100%.

Low-level radioactive waste from nuclear power generating stations: Characterization, classification and assessment of activated metals and waste streams  

SciTech Connect

Since the enactment of 10 CFR Part 61, additional difficult-to-measure long-lived radionuclides, not specified in Tables 1 2 of Part 61, have been identified (e.g., [sup 108m]Ag, [sup 93]Mo, [sup 36]Cl, [sup 10]Be, [sup 113m]Cd, [sup 121m]Sn, [sup 126]Sn, [sup 93m]Nb) that may be of concern in certain types of waste. These nuclides are primarily associated with activated metal and perhaps other nuclear power low-level waste (LLW) being sent to disposal facilities. The concentration of a radionuclide in waste materials is normally determined by direct measurement or by indirect calculational methods, such as using a scaling factor to relate inferred concentration of a difficult-to-measure radionuclide to another that is easily measured. The total disposal site inventory of certain difficult-to-measure radionuclides (e.g., [sup 14]C, [sup 129]I, and [sup 99]Tc) often control the total quantities of radioactive waste permitted in LLW burial facilities. Overly conservative scaling factors based on lower limits of detection (LLD), often used in the nuclear power industry to estimate these controlling nuclides, could lead to premature closure of a disposal facility. Samples of LLW (Class B and C activated metals [AM] and other waste streams) are being collected from operating nuclear power stations and analyzed for radionuclides covered in 10 CFR Part 61 and the additional difficult-to-measure radionuclides. This analysis will enhance the NRC's understanding of the distribution and projected quantities of radionuclides within AM and LLW streams from commercial nuclear power stations. This research will also provide radiological characterization of AM specimens for others to use in leach-rate and lysimeter experiments to determine nuclide releases and subsequent movement in natural soil environments.

Hydrogen Fuel Cell Analysis: Lessons Learned from Stationary Power Generation Final Report  

SciTech Connect

This study considered opportunities for hydrogen in stationary applications in order to make recommendations related to RD&D strategies that incorporate lessons learned and best practices from relevant national and international stationary power efforts, as well as cost and environmental modeling of pathways. The study analyzed the different strategies utilized in power generation systems and identified the different challenges and opportunities for producing and using hydrogen as an energy carrier. Specific objectives included both a synopsis/critical analysis of lessons learned from previous stationary power programs and recommendations for a strategy for hydrogen infrastructure deployment. This strategy incorporates all hydrogen pathways and a combination of distributed power generating stations, and provides an overview of stationary power markets, benefits of hydrogen-based stationary power systems, and competitive and technological challenges. The motivation for this project was to identify the lessons learned from prior stationary power programs, including the most significant obstacles, how these obstacles have been approached, outcomes of the programs, and how this information can be used by the Hydrogen, Fuel Cells & Infrastructure Technologies Program to meet program objectives primarily related to hydrogen pathway technologies (production, storage, and delivery) and implementation of fuel cell technologies for distributed stationary power. In addition, the lessons learned address environmental and safety concerns, including codes and standards, and education of key stakeholders.

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 on 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 pressurized water reactor (PWR) described in the earlier study; defining a formula for adjusting current cost estimates to reflect future escalation in labor, materials, and waste disposal costs; and completing a study of recent PWR steam generator replacements to determine realistic estimates for time, costs and doses associated with steam generator removal during decommissioning. This report presents the results of recent PNL studies to provide supporting information in four areas concerning decommissioning of the reference PWR: updating the previous cost estimates to January 1986 dollars; assessing the cost and dose impacts of post-TMI-2 backfits; assessing the cost and dose impacts of recent steam generator replacements; 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.

Analysis of populations of boring and fouling organisms in the vicinity of the Oyster Creek Nuclear Generating Station. Quarterly progress report No. 12, Jun-Aug 79  

SciTech Connect

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.

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.

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.

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.

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.

PHANTOM: A Monte Carlo event generator for six parton final states at high energy colliders  

NASA Astrophysics Data System (ADS)

PHANTOM is a tree level Monte Carlo for six parton final states at proton-proton, proton-antiproton and electron-positron colliders at O(?EM6) and O(?EM4?S2) including possible interferences between the two sets of diagrams. This comprehends all purely electroweak contributions as well as all contributions with one virtual or two external gluons. It can generate unweighted events for any set of processes and it is interfaced to parton shower and hadronization packages via the latest Les Houches Accord protocol. It can be used to analyze the physics of boson-boson scattering, Higgs boson production in boson-boson fusion, tt¯ and three boson production.

Nature of problem: Six fermion final state processes have become important with the increase of collider energies and are essential for the study of top, Higgs and electroweak symmetry breaking physics at high energy colliders. Since thousands of Feynman diagrams contribute in a single process and events corresponding to hundreds of different final states need to be generated, a fast and stable calculation is needed. Solution method:PHANTOM is a tree level Monte Carlo for six parton final states at proton-proton, proton-antiproton and electron-positron colliders. It computes all amplitudes at O(?EM6) and O(?EM4?s2) including possible interferences between the two sets of diagrams. The matrix elements are computed with the helicity formalism implemented in the program PHACT [1]. The integration makes use of an iterative-adaptive multichannel method which, relying on adaptivity, allows the use of only a few channels per process. Unweighted event generation can be performed for any set of processes and it is interfaced to parton shower and hadronization packages via the latest Les Houches Accord protocol. Restrictions: All Feynman diagrams are computed al LO. Unusual features: Phantom is written in Fortran 77 but it makes use of structures. The g77 compiler cannot compile it as it does not recognize the structures. The Intel, Portland Group, True64 HP Fortran 77 or Fortran 90 compilers have been tested and can be used. Running time: A few hours for a cross section integration of one process at per mille accuracy. One hour for one thousand unweighted events. References:A. Ballestrero, E. Maina, Phys. Lett.

UMTS Network Stations  

NASA Astrophysics Data System (ADS)

The weakness of small island electrical grids implies a handicap for the electrical generation with renewable energy sources. With the intention of maximizing the installation of photovoltaic generators in the Canary Islands, arises the need to develop a solar forecasting system that allows knowing in advance the amount of PV generated electricity that will be going into the grid, from the installed PV power plants installed in the island. The forecasting tools need to get feedback from real weather data in "real time" from remote weather stations. Nevertheless, the transference of this data to the calculation computer servers is very complicated with the old point to point telecommunication systems that, neither allow the transfer of data from several remote weather stations simultaneously nor high frequency of sampling of weather parameters due to slowness of the connection. This one project has developed a telecommunications infrastructure that allows sensorizadas remote stations, to send data of its sensors, once every minute and simultaneously, to the calculation server running the solar forecasting numerical models. For it, the Canary Islands Institute of Technology has added a sophisticated communications network to its 30 weather stations measuring irradiation at strategic sites, areas with high penetration of photovoltaic generation or that have potential to host in the future photovoltaic power plants connected to the grid. In each one of the stations, irradiance and temperature measurement instruments have been installed, over inclined silicon cell, global radiation on horizontal surface and room temperature. Mobile telephone devices have been installed and programmed in each one of the weather stations, which allow the transfer of their data taking advantage of the UMTS service offered by the local telephone operator. Every minute the computer server running the numerical weather forecasting models receives data inputs from 120 instruments distributed over the 30 radiometric stations. As a the result, currently it exist a stable, flexible, safe and economic infrastructure of radiometric stations and telecommunications that allows, on the one hand, to have data in real time from all 30 remote weather stations, and on the other hand allows to communicate with them in order to reprogram them and to carry out maintenance works.

The objectives of the study were to evaluate the thermal effects of the R. P. Smith steam Electric Station upon the finfish and macroinvertebrates communities during summer and fall, on the Potomac River. The finfish community was sampled during August and September 1980 with electrofishing gear. The increased water temperature along the Maryland shore appeared to influence the distribution of spotfin shiner and smallmouth bass. Carp, although not statistically tested, appeared to be more abundant in the thermal plume than at stations outside the thermal plume. The thermal discharge exhibited no discernible influence on the composition of the benthic or drift macroinvertebrate communities.

A solution of potassium nitrate and potassium chloride was injected at a precisely known concentration and rate for 25 hours into the feedwater to the steam generators. The injection period was sufficient to achieve equilibrium concentrations in the steam generators. Cation conductivity and impurity concentrations were monitored in the steam genrator blowdowns and throughout the system. Mass balance calculations were performed around the steam generators to estimate the hideout fraction and hideout rate constants for each of the injected species.

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.

This invention is comprised of a robotic station for dissolving active metals in acid in an automated fashion. A vessel with cap, containing the active metal is placed onto a shuttle which retracts to a point at which it is directly beneath a cap removing and retaining mechanism. After the cap is removed, a tube carrying an appropriate acid is inserted into the vessel, and the acid is introduced. The structure of the station forms an open hood which is swept of gases generated by the dissolution and the air removed to a remote location for scrubbing. After the reaction is complete, the shuttle extends and the vessel may be removed by a robot arm.

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.

System for the continuous generation of phosphorous aerosols from Red Phosphorus-Butyl Rubber. Final report  

SciTech Connect

A system for the continuous generation of phosphoric acid aerosols from burning Red Phosphorus-Butyl Rubber (RPBR) is described. The system is primarily intended for inhalation toxicology experiments using high aerosol concentrations (ca. 0.3 to 3 g/m/sup 3/), but is adaptable to other studies where a time independent concentration of the aerosol is desired in a flowing system. The RPBR formulation is softened by addition of a small amount of hexane and extruded at a controlled rate at high pressure through an orifice. A precision hydraulic extrusion system using a micrometer adjustable high pressure hydraulic pump has been developed to control the extrusion rate. The emerging filament is ignited and burned in a flowing air stream for delivery to chambers. In addition to the extrusion-combustion system for aerosol generation, devices for recovering the spent aerosol and for monitoring its concentration are described. 2 refs., 18 figs.

PWR radiation control: once-through steam generator studies. Final report  

SciTech Connect

Coordination of decreasing lithium concentration with decreasing boron concentration throughout a fuel cycle in the pressurized water reactor primary coolant is shown by theoretical calculations to be a strategy for control of out-of-core radiation fields. The strategy is supported by in-plant tests. This coordinated boron/lithium chemistry places constraints on the transports on the transport of corrosion products and their activation products in the primary coolant system. The use of hydrazine as a reducing agent and elevated lithium concentrations (1.8-2.0 ppM) in the coolant during shutdown/cooldown was also studied both in theoretical calculations and in plant tests. This was shown to have a controlling effect on corrosion product solubility but currently has limited potential for radiation field control. Thermal and hydraulic disturbances, single steam generator cooldowns, and secondary side steam generator heating for reversed heat flux were not found to be beneficial for radiation field control.

Examination of roller expansion transitions in Point Beach Unit 1 steam generator tubing: Final report  

SciTech Connect

The steam generators at Point Beach Unit 1 were replaced in 1983 because IGA in the part of the tubes within the tubesheet crevice required a power reduction that was unacceptable for long-term operation. Subsequent to the replacement, a section of the tubesheet containing 13 intact tubes and 16 split tubes around the periphery of the section was removed for examination by various contractors. The split tubes which are the subject of this report, were cleaned and examined by fluorescent penetrant inspection and metallography to determine the incidence of ID and OD cracking in the region of the roll transition. The results suggest that roll expansions of the type used in the Point Beach steam generators produce residual stresses high enough to cause OD stress corrosion cracking in aggressive environments. It appears that the residual stresses are not high enough to cause pure water stress corrosion cracking even in susceptible material. 8 refs.

Monitoring and control requirement definition study for dispersed storage and generation (DSG). Volume I. Final report  

SciTech Connect

Dispersed Storage and Generation (DSG) is the term that characterizes the present and future dispersed, relatively small (<30 MW) energy systems, such as solar thermal electric, photovoltaic, wind, fuel cell, storage battery, hydro, and cogeneration, that can help achieve national energy conservation goals and can be dispersed throughout the distribution portion of an electric utility system. A study of trends reveals that the need for DSG monitoring and control equipment by 1990 to 2000 will be great, measured in tens of thousands. Criteria for assessing DSG integration have been defined and indicate that economic and institutional as well as technical and other factors must be included. The principal emphasis in this report is on the functional requirements for DSG monitoring and control in six major categories. Twenty-four functional requirements have been prepared under these six categories and serve to indicate how to integrate the DSGs with the distribution and other portions of the electric utility system. The results indicate that there are no fundamental technical obstacles to prevent the connection of dispersed storage and generation to the distribution system. However, a communication system of some sophistication will be required to integrate the distribution system and the dispersed generation sources for effective control. The large-size span of generators from 10 kW to 30 MW means that a variety of remote monitoring and control may be required. The results show that an increased effort is required to develop demonstration equipment to perform the DSG monitoring and control functions and to acquire experience with this equipment in the utility distribution environment.

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.

An assessment of radiolytic gas generation: Impacts from Rocky Flats Plant residue elimination alternatives. Final report  

SciTech Connect

This report evaluates the Sandia National Laboratory-Albuquerque analytical model that is used to support present wattage limit decisions for various matrix forms from the Residue Elimination Project for Waste Isolation Pilot Plant waste acceptability. This study includes (1) a comparison of the SNL-A model to Rocky Flats Plant models for consistency of assumptions and the phenomena considered in the models, and (2) an evaluation of the appropriateness of the Sandia National Laboratory-Albuquerque model to Rocky Flats Plant residues, considering that the original intent was to model wastes rather than residues. The study draws the following conclusions: (1) only real-time gas generation testing of specific waste streams may provide a sound basis for an increase in the transportation wattage limit of specific waste streams, and (2) the radiolytic gas generation rate from Residue Elimination Project waste emplaced at Waste Isolation Pilot Plant, under worst-case conditions, is not a significant factor in comparison to the total gas generation rate due to radiolysis, microbial degradation, and corrosion.

Development of an Immersive Environment to Aid in Automatic Mesh Generation LDRD Final Report  

SciTech Connect

The purpose of this work was to explore the use of immersive technologies, such as those used in synthetic environments (commordy referred to as virtual realily, or VR), in enhancing the mesh- generation process for 3-dimensional (3D) engineering models. This work was motivated by the fact that automatic mesh generation systems are still imperfect - meshing algorithms, particularly in 3D, are sometimes unable to construct a mesh to completion, or they may produce anomalies or undesirable complexities in the resulting mesh. It is important that analysts and meshing code developers be able to study their meshes effectively in order to understand the topology and qualily of their meshes. We have implemented prototype capabilities that enable such exploration of meshes in a highly visual and intuitive manner. Since many applications are making use of increasingly large meshes, we have also investigated approaches to handle large meshes while maintaining interactive response. Ideally, it would also be possible to interact with the meshing process, allowing interactive feedback which corrects problems and/or somehow enables proper completion of the meshing process. We have implemented some functionality towards this end -- in doing so, we have explored software architectures that support such an interactive meshing process. This work has incorporated existing technologies developed at SandiaNational Laboratories, including the CUBIT mesh generation system, and the EIGEN/VR (previously known as MUSE) and FLIGHT systems, which allow applications to make use of immersive technologies and advanced human computer interfaces. 1

Fiber composite retaining rings for turbine-driven generators. Volume 1: material development. Final report  

SciTech Connect

The overall objectives of the Fiber Composite Retaining Rings for Turbine Driven Generators Program were to develop composite design data, construction techniques and methods of attachment that would support the application of graphite epoxy composites for electrical generator retaining rings. The contractor's approach to the design of an optimum graphite epoxy composite retaining ring involved a combined finite element analysis and material testing effort. The initial phase of this program (Material Development) dealt exclusively with development of the conventional strength of materials parameters under loading conditions representative of intended service requirements as well as special considerations related to the development of rational strength and fracture criteria for composites. Notched body, cracked body and combined mode loading considerations were addressed. The role of nondestructive testing in the characterizing of composite structure quality and overall structural integrity considerations was also included. Results from the vast number and variety of tests conducted in Phase I of the project combined to support the application of graphite epoxy composites for electrical generator retaining rings.

Performance evaluation of a pilot-scale permeable reactive barrier at former Naval Air Station Moffett Field, Mountain View, California: Volume 1. Final report, April 1996--November 1998  

SciTech Connect

A pilot scale permeable reactive barrier (PRB) or treatment wall demonstration project was initiated by the US Navy EFA West at the former Naval Air Station Moffett Field site in Mountain View, California about 3 years ago. Performance evaluations and cost-benefit analyses were performed by the US Naval Facilities Engineering Service Center (NFESC) and were sponsored by the Department of Defense (DoD) Environmental Security Technology Certification Program (ESTCP). The Moffett Field PRB uses a funnel-and-gate design, where the funnel is made of interlocking steel sheet piles and the gate consists of a reactive cell filled with zero-valent granular iron. Since its construction in April 1996, groundwater monitoring was conducted on a quarterly basis to demonstrate the effectiveness of the barrier technology in capturing and remediating groundwater that contained dissolved chlorinated hydrocarbon compounds. The primary contaminants of concern at Moffett Field in the vicinity of the PRB are trichloroethene, cis-1,2 dichloroethene, and perchloroethene at upgradient concentrations of about 2900 micrograms per liter, 280 micrograms/L, and 26 microgram/L, respectively. Quarterly monitoring events included water level measurements, field parameter testing, and groundwater sampling at about 75 monitoring points. Two tracer tests using bromide solutions and flow meter testing were also completed in April and August 1997 at the site. Iron cell coring samples were collected and analyzed in December 1997 for use as indicators of reactivity and longevity. Data from the quarterly monitoring, tracer testing, and iron cell coring have been used to determine the overall barrier performance. Since the first sampling event in June 1996, concentrations of all chlorinated compounds were either reduced to non-detect or to below the drinking water maximum contaminant levels within the first 2-3 feet of the permeable iron cell.

Third-generation foam blowing agents for foam insulation. Final report, October 1995--September 1997  

SciTech Connect

The report gives results of a study of third-generation blowing agents for foam insulation. The third phase focused on identifying blowing agent substitutes. The investigation concentrated on the development of techniques to identify and replace deficiencies that may be present in an individual substitute through the use of blowing agent azeotropic mixtures. The two components of a mixture may display a synergistic effect where the overall characteristics of the blowing agent are better than if either substance was used individually. The above concepts on blowing agent mixtures should encourage interested parties to investigate the use of azeotropes in laboratory foaming trials on insulating polyurethane foams.

Development work on a new package design for the next generation microelectronics. Final report  

SciTech Connect

AlliedSignal and Micro-Mode Products joined under a DOE CRADA to develop a new package for next-generation electronics devices. Requirements included low cost of manufacture, ability to satisfy thermal expansion requirements, ability to satisfy thermal dissipation requirements, acceptable digital and microwave performance, and hermeticity. Four processes were tested; vacuum deposition of paralene, epoxy powder coating, transfer molding, and manual encapsulation. Transfer molding and manual potting improved the hermeticity but produced microcracking and reduced heat transfer ability following encapsulation. Additional study on manufacturing and encapsulating of the package is needed.

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.

Maintenance and operation of a small wind generator in the marine environment. Final report  

SciTech Connect

This report discusses the maintenance and operation of a wind-turbine generator that has been undergoing tests as a source of energy for remote Coast Guard lighthouses. The report documents both the effects of operating the wind machine in the marine environment and the maintenance that it required. Design parameters and performance records of the generator are also evaluated. The HR2 is a horizontal-axis, upwind-oriented, three-bladed wind machine. It is equipped with a direct-drive system that allows the kinetic force captured by the propeller to be converted directly into rotational force driving the main shaft. The HR2 alternator and blade/hub system are allowed to tilt out of a near-vertical plane about a shaft and bearing mechanism. The VARCS is a torsion spring- and hinge-mechanism that acts against the lifting dynamics of the spinning blades. As high winds or gusts tilt the alternator about the hinge, the VARCS's spring opposes this force and regulates the blades angle of attack into the wind; the propeller's RPM drop when tilted because of the feathering action. If the wind subsides, the force of the VARCS spring drives the alternator assembly down and presents the blades back into the wind.

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.

Alternative solutions are desired for mid-wavelength and long-wavelength infrared radiation detection and imaging arrays. We have investigated quantum dot infrared photodetectors (QDIPs) as a possible solution for long-wavelength infrared (8 to 12 {mu}m) radiation sensing. This document provides a summary for work done under the LDRD 'Infrared Detection and Power Generation Using Self-Assembled Quantum Dots'. Under this LDRD, we have developed QDIP sensors and made efforts to improve these devices. While the sensors fabricated show good responsivity at 80 K, their detectivity is limited by high noise current. Following efforts concentrated on how to reduce or eliminate this problem, but with no clear path was identified to the desired performance improvements.

State-of-the-art study of nonconvective solar ponds for power generation. Final report  

SciTech Connect

A state-of-the-art study of non-convective solar ponds has been conducted to evaluate the potential use of the technology for the generation of electrical power. The basic physics and engineering of solar ponds have been established. Large solar pond systems were constructed in Israel, however, in the US the development of the technology has been at a modest scale. The ponds could be constructed using conventional methods to clear the site and to form the dikes. The power plants could be of conventional design except that refrigerant vapors may be used in place of steam for this application. No technical breakthroughs are required to implement this technology, although more information is needed to confirm that large ponds operate in a similar manner to small experimental solar ponds.

Work Element B: 157. Sampling in Fish-Bearing Reaches [Variation in Productivity in Headwater Reaches of the Wenatchee Subbasin], Final Report for PNW Research Station.  

SciTech Connect

We studied variation in productivity in headwater reaches of the Wenatchee subbasin for multiple field seasons with the objective that we could develop methods for monitoring headwater stream conditions at the subcatchment and stream levels, assign a landscape-scale context via the effects of geoclimatic parameters on biological productivity (macroinvertebrates and fish) and use this information to identify how variability in productivity measured in fishless headwaters is transmitted to fish communities in downstream habitats. In 2008, we addressed this final objective. In collaboration with the University of Alaska Fairbanks we found some broad differences in the production of aquatic macroinvertebrates and in fish abundance across categories that combine the effects of climate and management intensity within the subbasin (ecoregions). From a monitoring standpoint, production of benthic macroinvertebrates was not a good predictor of drifting macroinvertebrates and therefore might be a poor predictor of food resources available to fish. Indeed, there is occasionally a correlation between drifting macroinvertebrate abundance and fish abundance which suggests that headwater-derived resources are important. However, fish in the headwaters appeared to be strongly food-limited and there was no evidence that fishless headwaters provided a consistent subsidy to fish in reaches downstream. Fish abundance and population dynamics in first order headwaters may be linked with similar metrics further down the watershed. The relative strength of local dynamics and inputs into productivity may be constrained or augmented by large-scale biogeoclimatic control. Headwater streams are nested within watersheds, which are in turn nested within ecological subregions; thus, we hypothesized that local effects would not necessarily be mutually exclusive from large-scale influence. To test this we examined the density of primarily salmonid fishes at several spatial and temporal scales within a major sub-basin of the Columbia River and associations of density with ecoregion and individuals drainages within the sub-basin. We further examined habitat metrics that show positive associations with fish abundance to see if these relationships varied at larger spatial scales. We examined the extent to which headwater fish density and temporal variation in density were correlated between the headwaters and the main tributaries of the sub-basin, and the influence of ecoregion influence on density differences, particularly at wider temporal scales. Finally, we examined demographic parameters such as growth and emigration to determine whether density-dependence differs among ecoregions or whether responses were more strongly influenced by the demography of the local fish population.

Green inspection station  

NASA Astrophysics Data System (ADS)

As an effect of globalization, product parts are manufactured more and more in different places. Due to the manufacturing processes, (sub-) products are being transported back and forth and rearranged until they can finally reach the consumer. Not only the environment is increasingly burdened, but also the natural resources are wasted increasingly thoughtless. One reason is certainly because for decades the industry has had only an inflexible concept for the inspection of (sub-) products, which cannot be easily adapted to changes in product layout, for example one robot with one sensor or one rigid structure with a fixed number of sensors for one specific inspection task. This rigid approach is unsuitable for the inspection of variant products. For these reasons, a new concept for 2D and 3D metric and logical quality monitoring with a more accurate, flexible, economical and efficient inspection station has been developed and tested in IOSB.

Regional assessments of the hydrocarbon generation potential of selected North American Proterozoic rock sequences. Final report  

SciTech Connect

Whereas commercial production of Proterozoic-sourced oil and gas has been achieved in a few provinces (basins in the USSR, China and Oman), the potential for Proterozoic exploration targets in various basins in Africa, Asia, Australia and North America has been receiving increased attention. The authors have completed a geochemical survey study of over 500 core and outcrop samples that represent more than one dozen US Middle and Upper Proterozoic sedimentary formations. This included comprehensive sedimentologic/geochemical studies on two depositionally distinct, unmetamorphosed units, the Nonesuch Formation (1.1 Ga lacustrine rift deposit) and the Dripping Spring Quartzite (1.3 Ga marine shelf deposition) and reconnaissance work on samples collected from the Lower (1.2 to 1.3 Ga) Tindir Group in east-central Alaska. The primary objectives of this study were as follows: identify sources rocks by quantification and characterization of constituent organic matter; evaluate what depositional/diagenetic/catagenetic factors may have influenced source rock quality; and evaluate the possibility of previous hydrocarbon generation and migration using general petrologic, geochemical and geologic information. In addition to the primary goals, several contributions to the basic understanding of organic evolution have emerged from this study. These include: tentative confirmation of the occurrence of biomarkers (hopanes) in anhydrous pyrolyzates of kerogen from the Nonesuch Shale; microfossil evidence for eucaryote evolution in the Proterozoic rock record (Dripping Spring Quartzite); and an assessment of factors to be considered when attempting to establish stable isotope secular trends and apply isotope stratigraphy techniques to the Precambrian Era.

Test environments consisted primarily of anoxic brine with overpressures of N{sub 2}, CO{sub 2}, H{sub 2}S, and H{sub 2}. Limited tests of low-carbon steel were also performed in simulated-backfill environments and in brine environments with pH values ranging from 3 to 11. Low-carbon steel reacted at a slow, measurable rate with anoxic brine, liberating H{sub 2} on an equimolar basis with Fe reacted. Presence of CO{sub 2} caused the initial reaction to proceed more rapidly, but CO{sub 2}-induced passivation stopped the reaction if the CO{sub 2} were present in sufficient quantities. Addition of H{sub 2}S to a CO{sub 2}-passivated system caused reversal of the passivation. Low-carbon steel immersed in brine with H{sub 2}S showed no reaction, apparently because of passivation of the steel by formation of FeS. Addition of CO{sub 2} to an H{sub 2}S-passivated system did not reverse the passivation. Cu- and Ti-base materials showed essentially no corrosion when exposed to brine and overpressures of N{sub 2}, CO{sub 2}, and H{sub 2}S except for the rapid and complete reaction between Cu-base materials and H{sub 2}S. The Al-base materials reacted at approximately the same rate as low-carbon steel when immersed in anoxic Brine A; considerably more rapidly in the presence of CO{sub 2} or H{sub 2}S; and much more rapidly when iron was present in the system as a brine contaminant. High-purity Al was much more susceptible to corrosion than the 6061 alloy. No significant reaction took place on any material in any environment in the vapor-phase exposures.

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.

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.

World coverage for single station lightning detection  

NASA Astrophysics Data System (ADS)

This paper analyzes the possibility of using single station measurements of low-frequency electromagnetic waves to locate lightning occurring around much, and possibly all, of the world. The electromagnetic waves generated by lightning, which propagate through the Earth-ionosphere waveguide, are known as sferics. We combine a direction finding algorithm to compute the arrival azimuth of the recorded sferic along with a distance of propagation estimate to deduce the location of the lightning. While the methodology used for estimating the distance of propagation is described by Mackay and Fraser-Smith (2010), this paper analyzes the effectiveness of the method. We examine the limitations including those independent of station location and performance, and those which are station dependent. We analyze the geographic coverage attained from a single station along with the percentage of lightning emitting sferics that are recorded at the station and available for computing the lightning locations.

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.

Optimization of station battery replacement  

NASA Astrophysics Data System (ADS)

During a loss of ac power at a nuclear generating station (including diesel generators), batteries provide the source of power which is required to operate safety-related components. Because traditional lead-acid batteries have a qualified life of 20 years, the batteries must be replaced a minimum of once during a station's lifetime, twice if license extension is pursued, and more often depending on actual in-service dates and the results of surveillance tests. Replacement of batteries often occurs prior to 20 years as a result of systems changes caused by factors such as Station Blackout Regulations, control system upgrades, incremental load growth, and changes in the operating times of existing equipment. Many of these replacement decisions are based on the predictive capabilities of manual design basis calculations. The inherent conservatism of manual calculations may result in battery replacements occurring before actually required. Computerized analysis of batteries can aid in optimizing the timing of replacements as well as in interpreting service test data. Computerized analysis also provides large benefits in maintaining the as-configured load profile and corresponding design margins, while also providing the capability to quickly analyze proposed modifications and respond to internal and external audits.

Ground station digital interface  

NASA Astrophysics Data System (ADS)

Digital computer interface equipment was developed to enable the recovery of digital data encoded in special format and recorded, both in flight and in laboratory experiments, using an analog magnetic tape transport. The recorded data were first reproduced, in a continuous manner, at a ground station processing center, using an analogue magnetic tape reproducing machine and was then taken to the input of the interface equipment. Serial to parallel conversion of the data into 16-bit words suitable for direct entry into a computer, under interrupt control, was performed by the interface equipment. Time-of-day information which is normaly multiplexed with other digital data and recorded on the magnetic tape, effectively constitutes an identifier which may be used for specifying the location of any areas of interest on the tape. To enable the analog reproducing machine to be stopped at any predetermined location, a present stop signal generator was incorporated in the interface equipment. Complete details, together with a functional description, of each circuit within the digital interface equipment are included.

Applicability of Virtual Reference Stations for Static and Kinematic Positioning  

NASA Astrophysics Data System (ADS)

There is a possibility to generate artificial observations for a particular position by using a known Virtual Reference Station technique. It is done by transferring the observations from a physical reference station and interpolating the biases, usually using a network of reference stations. Theoretically, the measurements can replace the physical reference receiver and both, simplify and improve the processing of static and kinematic measurements. Here, the VRS is used as a control station for static and kinematic post-processing taking advantage of the network of reference stations by interpolating ionospheric and tropospheric biases to location of measurement. However previous computational experiments showed that the generated virtual observations are strongly correlated with the observations gathered at the nearest physical reference station. The previous studies were performed at close vicinity of the physical reference station. For further investigations of these correlations, and the issue of how do they influence processing results, a field experiment was designed and performed, in which the real measurements were taken at various distances from the physical reference station. Basing on these measurements, the correlations between the reference station and VRS stations were studied. The unknown physical stations were determined and used as a comparison for VRS measurements. Also, the applicability of VRS observations for static and kinematic processing was validated. To assure independence of calculations and results, besides commercial software (GNSS Solutions and LGO) chosen Precise Point Positioning services were used. The VRS data were obtained from the POZGEO-D service of the ASG-EUPOS network.

New approaches for the reduction of plasma arc drop in second-generation thermionic converters. Final report  

SciTech Connect

Investigations of ion generation and recombination mechanisms in the cesium plasma as they pertain to the advanced mode thermionic energy converter are described. The changes in plasma density and temperature within the converter have been studied under the influence of several promising auxiliary ionization candidate sources. Three novel approaches of external cesium ion generation have been investigated in some detail, namely vibrationally excited N/sub 2/ as an energy source of ionization of Cs ions in a DC discharge, microwave power as a means of resonant sustenance of the cesium plasma, and ion generation in a pulse N/sub 2/-Cs mixture. The experimental data obtained and discussed show that all three techniques - i.e. the non-LTE high-voltage pulsing, the energy transfer from vibrationally excited diatomic gases, and the external pumping with a microwave power - have considerable promise as schemes in auxiliary ion generation applicable to the advanced thermionic energy converter.

EUV spectroscopy of plasmas created in the final anode-cathode gap of the Z-Machine high-current pulsed generator (SNL)  

SciTech Connect

The effect of short-circuit across the final anode-cathode gap of powerful pulsed current generators could hamper efficient power delivery to the Z-pinch plasma. To study this effect, a novel EUV diagnostics of plasmas created in the final section of the transmission line (the anode-cathode gap near the main load) of the Z-Machine high-current generator (Sandia National Laboratories, United States) was developed. The work included developing spectroscopic instruments, theoretical and experimental studies of EUV spectra of iron ions in well-diagnosed laser-produced plasmas, and a comparison of these spectra with those of plasmas created in the final anode-cathode gap of the transmission line. The EUV spectra of highly charged Fe ions in the spectral range {lambda} {approx} 20-800 A were investigated. In experiments performed at Sandia National Laboratories, spectra of FeXIII-FeXVII ions were observed. A comparison of the measured and calculated spectra shows that the electron plasma temperature in the anode-cathode gap is T{sub e} {approx} 200 eV.

Retrieval of Intermediate Level Waste at Trawsfyndd Nuclear Power Station  

SciTech Connect

In 1996 RWE NUKEM Limited were awarded two contracts by BNFL Magnox Generation as part of the decommissioning programme for the Trawsfynydd power station. From the normal operations of the two Magnox reactors, intermediate level waste (ILW) had accumulated on site, this was Miscellaneous Activated Components (MAC) and Fuel Element Debris (FED). The objective of these projects is retrieval of the waste from storage vaults, monitoring, packaging and immobilization in a form suitable for on site storage in the medium term and eventual disposal to a waste repository. The projects involve the design, supply, commissioning and operation of equipment to retrieve, pack and immobilize the waste, this includes recovery from vaults in both reactor and pond locations and final decommissioning and removal of plant from site after completion of waste recovery.

Shoring pumping station excavation  

SciTech Connect

The city of San Mateo, Calif., operates three 12- to 50-year old wastewater pumping stations on a 24-m (80-ft) wide lot located in a residential area near San Francisco Bay. Because the aging stations have difficulty pumping peak 2.19-m{sup 3}/s (50-mgd) wet-weather flows and have structural and maintenance problems, a new 2.62-m{sup 3}/s (60-mgd) station was proposed - the Dale Avenue Pumping Station - to replace the existing ones. To prevent potential damage to adjacent homes, the new station was originally conceived as a circular caisson type; however, a geotechnical investigation recommended against this type of structure because the stiff soils could make sinking the structure difficult. This prompted an investigation of possible shoring methods for the proposed structure. Several shoring systems were investigated, including steel sheeting, soldier beams and lagging, tieback systems, open excavation, and others; however, each had disadvantages that prevented its use. Because these conventional techniques were unacceptable, attention was turned to using deep soil mixing (DSM) to create a diaphragm wall around the area to be excavated before constructing the pumping station. Although this method has been used extensively in Japan since 1983, the Dale Avenue Pumping Station would be the technology's first US application. The technology's anticipated advantages were its impermeability, its fast and efficient installation that did not require tiebacks under existing homes, its adaptability to subsurface conditions ranging from soft ground to stiff clay to gravels, and its lack of pile-driving requirements that would cause high vibration levels during installation.

The space station millimeter facility  

NASA Astrophysics Data System (ADS)

A large millimeter wavelength interferometer array is proposed for construction on the planned Space Station (The Space Station Millimeter Facility--SSMF). It will have manifold applications in both basic and applied research and will be the premier instrument in the world at high radio frequencies. Earth resource mapping, middle atmospheric studies, and high frequency radio astronomy are only a few of the areas which will be significantly advanced by the availability of such an instrument. Particularly in astronomy, the ability to do observations above the disturbing and absorbing effects of the Earth's atmosphere will allow opportunities for exploration of all objects from the Sun, through the Solar System bodies, to the interstellar medium of the Milky Way and other galaxies, and out to the most distant quasars with resolution and sensitivity equalling or exceeding all existing or planned millimeter wavelength telescopes. One of the last unexplored regions of the electromagnetic spectrum, the mm-IR gap, can finally be closed. A flexible design for the SSMF is proposed, and estimate of its construction costs is made, and numerous scientific applications in a number of disciplines are discussed.

During the past year significant results were achieved concerning ionospheric generation of ELF/VLF as well as ULF waves. A major breakthrough was participation in an experiment using the Arecibo facility in which a preliminary proof of principle of two of the relevant concepts was produced. 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.

Data collection and analysis in support of risk assessment for hydroelectric stations  

SciTech Connect

This project is to provide the U.S. Army Corps of Engineers with a risk analysis that evaluates the non-routine closure of water flow through the turbines of powerhouses along the Columbia and Snake Rivers. The project is divided into four phases. Phase 1 efforts collected and analyzed relevant plant failure data for hydroelectric generating stations in the United States and Canada. Results from the Phase 1 efforts will be used to assess the risk (probability times consequences) associated with non-routine shut down of hydroelectric stations, which will be performed in the remaining phases of the project. Results of this project may be used to provide policy recommendations regarding operation and maintenance of hydroelectric stations. The methodology used to complete the Phase 1 of the project is composed of data collection and analysis activities. Data collection included performing site visits, conducting a data survey of hydroelectric stations, conducting an expert panel workshop, and reviewing and tabulating failure data from generic sources. Data analysis included estimating failure rates obtained from the survey data, expert judgment elicitation process, generic data, and combining these failure rates to produce final failure rate parameters. This paper summarizes the data collection analysis, results and discussions for the Phase 1 efforts.

Transition metal catalysis in the generation of petroleum and natural gas. Final report, September 1, 1992--October 31, 1995  

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.

Final Report - Gas Generation Testing of Uranium Metal in Simulated K Basin Sludge and in Grouted Sludge Waste Forms  

SciTech Connect

The Waste Isolation Pilot Plant (WIPP) is being considered for the disposal of K Basin sludge as RH-TRU. Because the hydrogen gas concentration in the 55-gallon RH-TRU sealed drums to be transported to WIPP is limited by flammability safety, the number of containers and shipments likely will be driven by the rate of hydrogen generated by the uranium metal-water reaction (U + 2 H{sub 2}O {yields} UO{sub 2} + 2 H{sub 2}) in combination with the hydrogen generated from water and organic radiolysis. Gas generation testing was conducted with uranium metal particles of known surface area, in simulated K West (KW) Basin canister sludge and immobilized in candidate grout solidification matrices. This study evaluated potential for Portland cement and magnesium phosphate grouts to inhibit the reaction of water with uranium metal in the sludge and thereby permit higher sludge loading to the disposed waste form. The best of the grouted waste forms decreased the uranium metal-water reaction by a factor of four.

Final Results for the GRC Supporting Technology Development Project for the 110-Watt Stirling Radioisotope Generator (SRG110)  

NASA Astrophysics Data System (ADS)

From 1999-2006, the NASA Glenn Research Center (GRC) supported the development of a high-efficiency, nominal 110-We Stirling Radioisotope Generator (SRG110) for potential use on NASA missions, including deep space missions. Mars rovers, and lunar applications. Lockheed Martin (LM) was the system integrator for the SRG110, under contact to the Department of Energy (DOE). Infinia Corporation (formerly Stirling Technology Company) developed the Stirling converter. First as a contractor to DOE and then under subcontract to LM. The SRG110 development has been redirected, and recent program changes have been made to significantly increase the specific power of the generator. System development of an Advanced Stirling Radioisotope Generator (ASRG) has now begun, using a lightweight, advanced converter from Sunpower, Inc. This paper summarizes the results of the supporting technology effort that GRC completed for the SRG110. GRC tasks included converter extended-duration testing in air and thermal vacuum environments, heater head life assessment, materials studies, permanent magnet aging characterization, linear alternator evaluations, structural dynamics testing, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) characterization, organic materials evaluations, reliability studies, and development of an end-to-end system dynamic model. Related efforts are now continuing in many of these areas to support ASRG development.

The Western Area Power Administration (Western) proposes to construct, operate, and maintain a new Kiowa Creek Switching Station near Orchard in Morgan County, Colorado. Kiowa Creek Switching Station would consist of a fenced area of approximately 300 by 300 feet and contain various electrical equipment typical for a switching station. As part of this new construction, approximately one mile of an existing 115-kilovolt (kV) transmission line will be removed and replaced with a double circuit overhead line. The project will also include a short (one-third mile) realignment of an existing line to permit connection with the new switching station. In accordance with the Council on Environmental Quality (CEQ) regulations for implementing the procedural provisions of the National Environmental Policy Act of 1969 (NEPA), 40 CFR Parts 1500--1508, the Department of Energy (DOE) has determined that an environmental impact statement (EIS) is not required for the proposed project. This determination is based on the information contained in this environmental assessment (EA) prepared by Western. The EA identifies and evaluates the environmental and socioeconomic effects of the proposed action, and concludes that the advance impacts on the human environment resulting from the proposed project would not be significant. 8 refs., 3 figs., 1 tab.

Field evaluation of low-emission coal-burner technology on utility boilers. Volume 2. Second-generation low-NOx burners. Final report, September 1978-June 1986  

SciTech Connect

The report describes tests to evaluate the performance characteristics of three Second Generation Low-NOx burner designs: the Dual Register burner (DRB), the Babcock-Hitachi NOx Reducing (HNR) burner, and the XCL burner. The three represent a progression in development based on the original Babcock and Wilcox DRB. Of particular interest was the identification of burner configurations which would be suitable for application in the EPA LIMB (Limestone Injection Multistage Burner) technology demonstration program at Ohio Edison's Edgewater Station, Unit 4. The retrofit requirements for this unit were used to establish burner performance criteria. The testing was conducted with nominal full-scale burner designs, having a capacity of 78 million Btu/hr (22.0 MW). Each burner was tested over a wide range of operating conditions and hardware configurations, and with different coals. However, the XCL burner was judged to have the best overall performance and to meet all the Edgewater boiler retrofit requirements. Additional brief tests were conducted to evaluate the impact of burner design on SO2 removal by injected sorbent materials.

The major elements of this study were: (1) acquisition of detailed piping layouts and installed insulation details for a reference BWR; (2) analysis of plant specific piping weld failure probabilities to estimate the LOCA frequency; (3) development of an insulation and other debris generation and drywell transport models for the reference BWR; (4) modeling of debris transport in the suppression pool; (5) development of strainer blockage head loss models for estimating loss of NPSH margin; (6) estimation of core damage frequency attributable to loss of ECCS recirculation capability following a LOCA. Elements 2 through 5 were combined into a computer code, BLOCKAGE 2.3. A point estimate of overall DEGB pipe break frequency (per Rx-year) of 1.59E-04 was calculated for the reference plant, with a corresponding overall ECCS loss of NPSH frequency (per Rx-year) of 1.58E-04. The calculated point estimate of core damage frequency (per Rx-year) due to blockage related accident sequences for the reference BWR ranged from 4.2E-06 to 2.5E-05. The results of this study show that unacceptable strainer blockage and loss of NPSH margin can occur within the first few minutes after ECCS pumps achieve maximum flows when the ECCS strainers are exposed to LOCA generated fibrous debris in the presence of particulates (sludge, paint chips, concrete dust). Generic or unconditional extrapolation of these reference plant calculated results should not be undertaken.

Methane utilization from coalbeds for power generation at Bethlehem Mines Corporation Marianna Mine No. 58. Final report  

SciTech Connect

During one process of mining coal, methane is removed from the coal seam before the coal is mined. This methane is collected underground, piped to the surface, and exhausted to the atmosphere as a waste by-product of the mining process. An electrical power generation system was assembled to demonstrate utilization of this energy source. An 800 kW gas turbine generator with attendant compression and electrical equipment converted 200,000 standard cubic feet per day of methane to about 250 kWh. This electrical power was utilized by a mine surface load consisting of a 100 hp air compressor and a 300 hp mine ventilation fan. Power generated represented about 25% of the total energy used in all the mine ventilation systems or about 5% of the total underground mine electrical requirements. The main conclusions of the work performed is that low Btu gob gas in the range of 100 to 400 Btu/ft/sup 3/ can be combusted successfully in a diffusion flame system. The efficiencies that can be achieved are high and in general stability is adequate. Both the efficiency and stability range achieved were sufficient to indicate that a gas turbine could be operated with such fuels over a normal operating cycle. One problem that was noticed during earlier investigations is that because of the low energy content of the fuel, heat losses in the combustor can significantly affect performance, particularly stability. In general such combustion systems should be maintained as near adiabatic as possible and should operate with as high a wall temperature as is possible. Further research and development will be required of any scaled combustion system before it could be considered a suitable candidate for engine installation.

Hydrogen Filling Station  

SciTech Connect

Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created. This roadmap has the ability to become a tool for use by other road-mapping efforts in the hydrogen community. It could also become a standard template for other states or even countries to approach planning for a hydrogen future. Project partners also conducted a workshop on hydrogen safety and permitting. This provided an opportunity for the various permitting agencies and end users to gather to share experiences and knowledge. As a result of this workshop, the permitting process for the hydrogen filling station on the Las Vegas Valley Water District’s land was done more efficiently and those who would be responsible for the operation were better educated on the safety and reliability of hydrogen production and storage. The lessons learned in permitting the filling station and conducting this workshop provided a basis for future hydrogen projects in the region. Continuing efforts to increase the working pressure of electrolysis and efficiency have been pursued. Research was also performed on improving the cost, efficiency and durability of Proton Exchange Membrane (PEM) hydrogen technology. Research elements focused upon PEM membranes, electrodes/catalysts, membrane-electrode assemblies, seals, bipolar plates, utilization of renewable power, reliability issues, scale, and advanced conversion topics. Additionally, direct solar-to-hydrogen conversion research to demonstrate stable and efficient photoelectrochemistry (PEC) hydrogen production systems based on a number of optional concepts was performed. Candidate PEC concepts included technical obstacles such as inefficient photocatalysis, inadequate photocurrent due to non-optimal material band gap energies, rapid electron-hole recombination, reduced hole mobility and diminished operational lifetimes of surface materials exposed to electrolytes. Project Objective 1: Design, build, operate hydrogen filling station Project Objective 2: Perform research and development for utilizing solar technologies on the hydrogen filling station and convert two utility vehicles for use by the station operators Project Objective 3: Increase capacity of hydrogen filling station; add additional vehicle; conduct safety workshop; develop a roadmap for hydrogen development; accelerate the development of photovoltaic components Project Objective 4:

Measurement of pH and corrosion potentials of tube alloys in solutions found in steam generators: Final report  

SciTech Connect

Two of the most important parameters in defining the chemical and corrosion properties of reactor heat transport systems are the electrochemical potential and pH, both measured at the temperature of operation. The overall goal of this research program was to use several techniques developed at SRI over the last several years to measure the pH of various solutions in the temperature range 25C to 300C, and the electrochemical potential of alloy 600 and 690 in these carefully defined solutions. The YSZ pH electrode has the advantage that it can measure the pH in solutions where the hydrogen (platinum) electrode fails because the latter is affected by the redox potential of the solution and by other limitations. After the calibration was complete, the YSZ pH sensor was used to measure the pH of solutions over the temperature range 125C to 300C. In general, both acidic as well as alkaline solutions moved toward neutral pH values with increasing temperature. Finally, the corrosion potentials of Inconel 600 and 690 alloys measured as a function of temperature indicated that, in general, in acidic solutions, both alloys behave similar to the hydrogen electrode. However, in basic and neutral solutions, the potentials of the alloys and the hydrogen electrode were different, possibly due to the presence of dissolved oxygen (175 ppB) in our system.

Toxicology Studies on Lewisite and Sulfur Mustard Agents: Two-Generation Reproduction Study of Lewisite in Rats Final Report  

SciTech Connect

Occupational health standards have not been established for Lewisite [bis(2-chlorethyl)arsine], a potent toxic vesicant which reacts with the sulfhydryl groups of proteins through its arsenic group. The purposes of this study were to determine the reproductive consequences and dose~response of continuing Lewisite exposure of parental males and females and their offspring in a 42-week two-generation study. Solutions of Lewisite were prepared for administration by diluting the neat agent with sesame oil. Rats were administered Lewisite (0, 0.10, 0.25 or 0.60 mg/kg/day for 5 days a week) via intragastric intubation prior to mating, during mating and after mating until the birth of their offspring. The dams continued to receive Lewisite during lactation. At weaning, male and female offspring of each group were selected to continue on the study; rece1v1ng Lewisite during adolescence, mating and throughout gestation. Again, the dams continued to receive Lewisite until weaning of the offspring. Lewisite had no adverse effect on reproduction performance, fertility or reproductive organ weights of male or female rats through two consecutive generations. No adverse effect to offspring were attributed to Lewisite exposure. Minor changes in growth was the only maternal effect observed. Lewisite exposure of parental rats caused no gross or microscopic lesions in testes, epididymis, prostrate, seminal vesicles, ovaries, uterus or vagina. Severe inflammation of the lung was observed at necropsy in cases in which Lewisite gained access to the respiratory system from accidental dosing or reflux and aspiration; this usually caused early death of the animal. The NOEL for reproductive effects in this study was greater than 0.60 mg/kg/day.

Supplemental examination of alternative materials in a model steam generator: Volume 2, Correlation of Model 10 defects with eddy-current indications: Final report  

SciTech Connect

The following report compares the nondestructive examination with the destructive metallographic examination of the tube bundle alternative materials, Model 10 steam generator. The model steam generator was fabricated using state-of-the-art tube processing (Alloys 600, 690 and 800) and corrosion resistant support alloys and designs. The model steam generator was operated for approximately one year with a secondary environment that was faulted with acidified simulated cooling tower water and sludge. The tube bundle was eddy current tested at the final inspection using multiple frequency differential and absolute mode probes and state-of-the-art eddy current equipment, including a computerized system for data analysis. Various frequency mixes were designed to suppress signals from deposits and to improve signal to noise ratios. Special tests were utilized to evaluate the Alloy 800 tubing. Eddy current data correlated favorably with results from the destructive examinations. Generally eddy current tests were most successful in detecting axial cracks, circumferential cracks, defects with depths greater than 10% throughwall and tube denting at trefoil supports. It was not possible to distinguish between cracks and deep wastage. Interpretation of the eddy current indications predicted corrosion damage deeper than that found metallographically for conservative depth estimates. Numerous false defect indications, with low signal to noise ratios, were produced by the presence of conductive deposits on the O.D. of the tubing. Absolute mode testing provided a reliable qualitative indication of tube corrosion despite the interference from the conductive deposits. 4 refs., 1 fig., 1 tab.

Proceedings of the 2. MIT international conference on the next generation of nuclear power technology. Final report  

SciTech Connect

The goal of the conference was to try to attract a variety of points of view from well-informed people to debate issues concerning nuclear power. Hopefully from that process a better understanding of what one should be doing will emerge. In organizing the conference lessons learned from the previous one were applied. A continuous effort was made to see to it that the arguments for the alternatives to nuclear power were given abundant time for presentation. This is ultimately because nuclear power is going to have to compete with all of the energy technologies. Thus, in discussing energy strategy all of the alternatives must be considered in a reasonable fashion. The structure the conference used has seven sessions. The first six led up to the final session which was concerned with what the future nuclear power strategy should be. Each session focused upon a question concerning the future. None of these questions has a unique correct answer. Rather, topics are addressed where reasonable people can disagree. In order to state some of the important arguments for each session`s question, the combination of a keynote paper followed by a respondent was used. The respondent`s paper is not necessarily included to be a rebuttal to the keynote; but rather, it was recognized that two people will look at a complex question with different shadings. Through those two papers the intention was to get out the most important arguments affecting the question for the session. The purpose of the papers was to set the stage for about an hour of discussion. The real product of this conference was that discussion.

Final Report on Utilization of TRU TRISO Fuel as Applied to HTR Systems Part II: Prismatic Reactor Cross Section Generation  

SciTech Connect

The deep-burn prismatic high temperature reactor is made up of an annular core loaded with transuranic isotopes and surrounded in the center and in the periphery by reflector blocks in graphite. This disposition creates challenges for the neutronics compared to usual light water reactor calculation schemes. The longer mean free path of neutrons in graphite affects the neutron spectrum deep inside the blocks located next to the reflector. The neutron thermalisation in the graphite leads to two characteristic fission peaks at the inner and outer interfaces as a result of the increased thermal flux seen in those assemblies. Spectral changes are seen at least on half of the fuel blocks adjacent to the reflector. This spectral effect of the reflector may prevent us from successfully using the two step scheme -lattice then core calculation- typically used for light water reactors. We have been studying the core without control mechanisms to provide input for the development of a complete calculation scheme. To correct the spectrum at the lattice level, we have tried to generate cross-sections from supercell calculations at the lattice level, thus taking into account part of the graphite surrounding the blocks of interest for generating the homogenised cross-sections for the full-core calculation. This one has been done with 2 to 295 groups to assess if increasing the number of groups leads to more accurate results. A comparison with a classical single block model has been done. Both paths were compared to a reference calculation done with MCNP. It is concluded that the agreement with MCNP is better with supercells, but that the single block model remains quite close if enough groups are kept for the core calculation. 26 groups seems to be a good compromise between time and accu- racy. However, some trials with depletion have shown huge variations of the isotopic composition across a block next to the reflector. It may imply that at least an in- core depletion for the number density calculation may be necessary in the complete calculation scheme.

NASA Astrophysics Data System (ADS)

The Medicina 32-m dish is an alt-az antenna run by the Istituto di Radioastronomia di Bologna del Consiglio Nazionale delle Ricerche. The radiotelescope is located about 30 km east of Bologna, Italy. It is part of the European VLBI Network. Details on the telescope characteristics and equipments can be found at the EVN Home Page (http://www.nfra.nl/evn/). In the last couple of years, the main goal at the Medicina Station was to get the telescope agile in changing the observing frequency. Achieving this goal will greatly increase the observational efficiency of the telescope. Moreover it will make the operation of changing the receivers more safe and it makes this task independent of weather conditions. The first part of the project has been completed and the new subreflector is fully in operation. The increased flexibility in changing frequency, together with the facility of recording both thick and thin tapes implemented at all the European VLBI Network (EVN) stations has immediately produced an increase in the number of geodetic VLBI observations to which the Medicina Station will take part in 1999.

FY06 LDRD Final Report Next-generation x-ray optics: focusing hard x-rays  

SciTech Connect

The original goal of our research was to open up a new class of scientific experiments by increasing the power of newly available x-ray sources by orders of magnitude. This was accomplished by developing a new generation of x-ray optics, based on hard x-ray (10-200 keV) reflective and diffractive focusing elements. The optical systems we envision begin with a core reflective optic, which has the ability to capture and concentrate x-rays across a wide range of energies and angles band, combined with diffractive optics, based on large-scale multilayer structures, that will further enhance the spatial, spectral and temporal resolving power of the system. Enabling technologies developed at LLNL such as precise mounting of thermally formed substrates, smoothing techniques and multilayer films of ultra-high reflectance and precision were crucial in the development and demonstration of our research objectives. Highlights of this phase of the project include: the design and fabrication of a concentrator optic for the Pleiades Thomson X-ray source located at LLNL, smoothing of glass substrates through application of polyimide films, and the design, fabrication and testing of novel volume multilayers structures. Part of our research into substrate smooth led to the development of a new technique (patent pending) to construct high-quality, inexpensive x-ray optics. This innovation resulted in LLNL constructing a x-ray optic for the CERN Axion Solar Telescope (CAST) and allowed LLNL to join the international experiment.

Monolithic solid oxide fuel cell technology advancement for coal-based power generation. Final report, September 1989--March 1994  

SciTech Connect

This project has successfully advanced the technology for MSOFCs for coal-based power generation. Major advances include: tape-calendering processing technology, leading to 3X improved performance at 1000 C; stack materials formulations and designs with sufficiently close thermal expansion match for no stack damage after repeated thermal cycling in air; electrically conducting bonding with excellent structural robustness; and sealants that form good mechanical seals for forming manifold structures. A stack testing facility was built for high-spower MSOFC stacks. Comprehensive models were developed for fuel cell performance and for analyzing structural stresses in multicell stacks and electrical resistance of various stack configurations. Mechanical and chemical compatibility properties of fuel cell components were measured; they show that the baseline Ca-, Co-doped interconnect expands and weakens in hydrogen fuel. This and the failure to develop adequate sealants were the reason for performance shortfalls in large stacks. Small (1-in. footprint) two-cell stacks were fabricated which achieved good performance (average area-specific-resistance 1.0 ohm-cm{sup 2} per cell); however, larger stacks had stress-induced structural defects causing poor performance.

Vibration measurements were collected at the Precision Measurement Equipment Laboratory (PMEL) and Fire Station buildings during operations of the A/F32T-9 Large Turbo Fan Engine, Enclosed Noise Suppressor System (T-9 NSS) at McConnell AFB KS. The highest vibration levels were measured with an F101 engine operating at afterburner power in the T-9 NSS. The measured floor-vibration levels are well below both the limits recommended to prevent adverse health effects and those limits recommended to prevent decrease in proficiency at performing work tasks. The measured floor-vibration levels do not even exceed the threshold of perception of the most-sensitive individuals to whole-body vibration. Measurements did not rule out the possibility of exceeding recommended levels for interference with vibration sensitive calibrations at the PMEL buildings.

Ultracoatings: Enabling Energy and Power Solutions in High Contact Stress Environments through next-generation Nanocoatings Final Technical Report  

SciTech Connect

A review of current commercially available, industrial-grade, low friction coatings will show that interfacial contact pressures nearing 1GPa ({approx}150ksi) inherently limit surface engineering solutions like WC, TiN, TiAlN, and so forth. Extremely hard coatings, then, are often pursued as the principle path, although they too are not without significant limitations. A majority of these compounds are inherently brittle in nature or may not pair well with their mating substrate. In either case, their durability in high contact stress environments is compromised. In parallel to thin film coatings, many conventional surface treatments do not yield an interface hard enough to withstand extreme stresses under load. New research into advanced, nanocomposite materials like (Ti, Zr)B2 shows great promise. Bulk compacts of this compound have demonstrated an order of magnitude better wear resistance than current offerings, notably materials like tungsten carbide. At a laboratory level, the (Ti,Zr)B2 nanocomposite material exhibited abrasive and erosive wear resistance nearly ten times better than existing mixed-phase boride systems. In ASTM abrasion and erosion testing, these new compositions exhibit wear resistance superior to other known advanced materials such as RocTec 500 and 'Borazon' cubic boron nitride. Many significant challenges exist for mass production of (Ti, Zr)B2, one of which is the necessary processing technology that is capable of minimizing deleterious impurity phases. Secondly, this material's performance is derived from a synergistic effect of the two materials existing as a single phase structure. While the individual constituents of TiB2 and ZrB2 do yield improvements to wear resistance, their singular effects are not as significant. Lastly, deposition of this material on a commercial level requires thorough knowledge of nanocomposite boride solids; the benefits associated with these innovative new materials are just being realized. Advancing this technology, called Ultracoatings, through initial development, scale up, and commercialization to a variety of markets would represent a transformative leap to surface engineering. Several application spaces were considered for immediate implementation of the Ultracoatings technology, including, but not limited to, a drive shaft for an aerospace fuel pump, engine timing components, and dry solids pump hardware for an innovative coal gasifier. The primary focus of the program was to evaluate and screen the performance of the selected (Ti, Zr)B2 Ultracoatings composition for future development. This process included synthesis of the material for physical vapor deposition, sputtering trials and coating characterization, friction and wear testing on sample coupons, and functional hardware testing. The main project deliverables used to gage the project's adherence to its original objective were: Development of a coating/substrate pairing that exhibits wear rate of 0.1 mg/hour or lower at a 1GPa contact pressure, while achieving a maximum coating cost of $0.10/cm2. Demonstrate the aforementioned wear rate in both lubricated and starved lubrication conditions. Although the (Ti, Zr) B2 coating was not tailored for low friction performance, friction and wear evaluations of the material demonstrated a coefficient of sliding friction as low as 0.09. This suggests that varying the percentage of TiB2 present in the composite could enhance the materials performance in water-based lubricants. In the aerospace drive shaft application, functional hardware coated with (Ti, Zr)B2 survived a variety of abuse and long-range durability tests, with contact pressures exceeding 2 GPa. For engine timing components, further work is planned to evaluate the Ultracoatings technology in direct injection and diesel engine conditions. In the final identified application space the dry solids pump hardware, discussions continue on the application of the Ultracoatings technology for those specific components. Full implementation of the technology into the targeted markets equates to a U.S.-based en

NEXT GENERATION SOLVENT-MATERIALS COMPATIBILITY WITH POLYMER COMPONENTS WITHIN MODULAR CAUSTIC-SIDE SOLVENT EXTRACTION UNIT (FINAL REPORT)  

SciTech Connect

The Office of Waste Processing, within the Office of Technology Innovation and Development, is funding the development of an enhanced solvent for deployment at the Savannah River Site for removal of cesium from High Level Waste. The technical effort is collaboration between Oak Ridge National Laboratory (ORNL), Savannah River National Laboratory (SRNL), and Argonne National Laboratory. The first deployment target for the technology is within the Modular Caustic-Side Solvent Extraction Unit (MCU). Deployment of a new chemical within an existing facility requires verification that the chemical components are compatible with the installed equipment. In the instance of a new organic solvent, the primary focus is on compatibility of the solvent with organic polymers used in the facility. This report provides the data from exposing these polymers to the Next Generation Solvent (NGS). The test was conducted over six months. An assessment of the dimensional stability of polymers present in MCU (i.e., PEEK, Grafoil, Tefzel and Isolast) in the modified NGS (where the concentration of LIX{reg_sign}79 and MaxCalix was varied systematically) showed that LIX{reg_sign}79 selectively affected Tefzel and its different grades (by an increase in size and lowering its density). The copolymer structure of Tefzel and possibly its porosity allows for the easier diffusion of LIX{reg_sign}79. Tefzel is used as the seat material in some of the valves at MCU. Long term exposure to LIX{reg_sign}79, may make the valves hard to operate over time due to the seat material (Tefzel) increasing in size. However, since the physical changes of Tefzel in the improved solvent are comparable to the changes in the CSSX baseline solvent, no design changes are needed with respect to the Tefzel seating material. PEEK, Grafoil and Isolast were not affected by LIX{reg_sign}79 and MaxCalix within six months of exposure. The initial rapid weight gain observed in every polymer is assigned to the finite and limited uptake of Isopar{reg_sign} L/Modifier by the polymers probably due to the polymers porosity and rough surfaces. Spectroscopic data on the organic liquid and the polymer surfaces showed no preferential adsorption of any component in the NGS to the polymers and with the exception of CPVC, no leachate was observed in the NGS from any of the polymers studied. The testing shows no major concerns for compatibility over the short duration of these tests but does indicate that longer duration exposure studies are warranted, especially for Tefzel. However, the physical changes experienced by Tefzel in the improved solvent were comparable to the physical changes obtained when Tefzel is placed in CSSX baseline solvent. Therefore, there is no effect of the improved solvent beyond those observed in CSSX baseline solvent.

High speed imager test station  

DOEpatents

A test station enables the performance of a solid state imager (herein called a focal plane array or FPA) to be determined at high image frame rates. A programmable waveform generator is adapted to generate clock pulses at determinable rates for clock light-induced charges from a FPA. The FPA is mounted on an imager header board for placing the imager in operable proximity to level shifters for receiving the clock pulses and outputting pulses effective to clock charge from the pixels forming the FPA. Each of the clock level shifters is driven by leading and trailing edge portions of the clock pulses to reduce power dissipation in the FPA. Analog circuits receive output charge pulses clocked from the FPA pixels. The analog circuits condition the charge pulses to cancel noise in the pulses and to determine and hold a peak value of the charge for digitizing. A high speed digitizer receives the peak signal value and outputs a digital representation of each one of the charge pulses. A video system then displays an image associated with the digital representation of the output charge pulses clocked from the FPA. In one embodiment, the FPA image is formatted to a standard video format for display on conventional video equipment.

PlayStation purpura.  

PubMed

A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller. The lesions completely resolved following abstinence from gaming over a number of weeks. Although the parallel ridge pattern is typically the hallmark for early acral lentiginous melanoma, it may be observed in a limited number of benign entities, including subcorneal haematoma.

Time series analysis of EPN stations as a criterion of choice of reference stations for local geodynamic networks  

NASA Astrophysics Data System (ADS)

Local and regional geodynamic studies require evaluation of inner (intraplate) velocities, primarily reference points' velocities. Relative velocities between selected European Permanent Network (EPN) stations can be evaluated using different approaches (time series analysis, ITRF2000 velocities, NUVEL1A-NNR velocities). The authors present the method of mean trend congruency analysis for EPN stations coordinate time series (from weekly EUREF solutions). The article includes results of time series analysis of EPN stations located no more than 700 km away from our local geodynamic network (LGN) SUDETES located in Sudety Mts. and Sudetic Foreland (Central Europe), performed for a selection of the best reference stations. Taking into account the results of performed classification and the distance between stations and local research area (Sudety Mts., SW Poland), the best conditions of local measurements' connection to the European network have been fulfilled for the stations: BOR1, PENC, GOPE, GRAZ WTZR and POTS. Stations, such as WROC and MOPI, located close to the research area are characterized by significantly worse quality parameters. Finally the influence of reference station selection on estimated velocities of local geodynamic network points is shown. The authors participate in EPN Special Project: Time series monitoring for geokinematics (Central Europe subjetwork).
