The effect of Coulomb multipole scattering on the beam emittance is studied with the 6 dimensional injection program ARCHSIM by A. Thiessen. Since the energy loss due to Bhabha scattering is small, the six dimensional simulation can be approximated into transverse 4 dimensional and longitudinal 2 dimensional tracking. The emittance growth agrees well with the multiple scattering theory. The beam loss occurs mainly in the adiabatic capture process in the longitudinal phase space.

An experimental set-up for accurate measurement of hydrogen generation rate in Lithium-Lead (Li[sub 17]Pb[sub 83]) Steam or water interactions has been designed. The most important features of the design include a pneumatic actuated quick opening and closing high temperature all stainless steel valve used to control the reaction time and the placement of most measuring devices below a water line to minimize leakage of the hydrogen collected. A PC based data acquisition and control system provides remote process sequencing, acquisition and control of all major components of the set-up. Initial tests indicate that the first design objective of maintaining leakproof gas collection chamber has been achieved. Initial pressure tests indicated that the pressure drop over a time span of 30 minutes was within the tolerance of the pressure transducer used to measure the pressure (within 0.690 kPa) at a nominal system pressure of 685 kPa. The experimental system hardware, data acquisition and control programs and data analysis program have been completed, tested and are currently functional.

The Oak Ridge Reservation Hydrology and Geology Study (ORRHAGS) Groundwater Data Base has been compiled to consolidate groundwater data from the three US Department of Energy facilities located on the Oak Ridge Reservation: the Oak Ridge K-25 Site, the Oak Ridge National Laboratory, and the Oak Ridge Y-12 Plant. Each of these facilities maintains its own groundwater and well construction data bases. Data were extracted from the existing data bases, converted to a consistent format, and integrated into the ORRHAGS Groundwater Data Base structures. This data base dictionary describes the data contained in the ORRHAGS Groundwater Data Base and contains information on data base structure, conventions, contents, and use.

The objective of this program is to develop advanced concepts for the removal of NO[sub x] from flue gas emitted by coal-fired utility boilers, or for the control of NO[sub x] formation by advanced combustion modification techniques. Funded projects are required to focus on the development of technology that significantly advances the state of the art using a process or a combination of processes capable of reducing NO[sub x] emissions to 60 ppM or less. The concept must have successfully undergone sufficient laboratory-scale development to justify scaleup for further evaluation at the pilot scale (not to exceed 5 MWe in size). Other requirements include production of a nonhazardous waste or a salable by-product. The concept should have application to both new and retrofit coal-fired systems and show the potential for a 50% cost savings when compared to a commercial selective catalytic reduction (SCR) process capable of meeting the 60-ppM NO[sub x] emission limit. The EERC approach to meeting the program objective involves the development of a catalytic fabric filter for simultaneous NO[sub x] and particulate control. The NO[sub x] is removed by catalytic reduction with ammonia to form nitrogen and water. The catalyst employed at this time is vanadium/titanium, but …

This document provides a discussion of the technical progress on DOE-PETC Project Number AC22-92PC91338, High Efficiency SO[sub 2] Removal Testing,'' for the time period from January 1 through March 31, 1993. The project involves testing at full-scale utility flue gas desulfurization (FGD) systems to evaluate low capital cost upgrades that may allow these systems to achieve up to 98% SO[sub 2] removal efficiency. The options to be evaluated primarily involve the addition of organic acid buffers to the FGD systems. The base'' project involves testing at one site, Tampa Electric Company's Big Bend Station. Up to five optional sites may be added to the program at the discretion of DOE-PETC. By March 31, 1993, four of those five options had been exercised. The options include testing at Hoosier Energy's Merom Station (Option I), Southwestern Electric Power Company's (SWEPCo) Pirkey Station (Option II), PSI Energy's Gibson Station (Option III), and Duquesne Light's Elrama Station (Option IV). The remainder of this document is divided into three sections. Section 2, Project Summary, provides a brief overview of the technical efforts on this project during the quarter. Section 3, Results, summarizes the outcome of those technical efforts. Results for the Base Program and for …

The purpose of this contract is to develop and refine the Integrated Environmental Control Model (IECM) created and enhanced by Carnegie Mellon University (CMU) for the US Department of Energy's Pittsburgh Energy Technology Center (DOE/PETC) under contract Numbers FG22-83PC60271 and AC22-87PC79864. In its current configuration, the IECM provides a capability to model various conventional and advanced processes for controlling air pollutant emissions from coal-fired power plants before, during, or after combustion. The principal purpose of the model is to calculate the performance, emissions, and cost of power plant configurations employing alternative environmental control methods. The model consists of various control technology modules, which may be integrated into a complete utility plant in any desired combination. In contrast to conventional deterministic models, the IECM offers the unique capability to assign probabilistic values to all model input parameters, and to obtain probabilistic outputs in the form of cumulative distribution functions indicating the likelihood of different costs and performance results. The work in this contract is divided into two phases. Phase I deals with further developing the existing version of the IECM and training PETC personnel on the effective use of the model. Phase II deals with creating new technology modules, linking the …

During fourth quarter 1992, samples from the three monitoring wells at the K-Area site (KSS series) and the three monitoring wells at the Par Pond site (PSS series) were analyzed for constituents required by South Carolina Department of Health and Environmental Control Construction Permit 13, 173 and for other constituents as part of the Savannah River Site (SRS) Groundwater Monitoring Program. This report describes monitoring results that exceeded the final Primary Drinking Water Standards (PDWS) or the SRS flagging criteria. During fourth quarter 1992, no constituents analyzed exceeded the PDWS or the SRS Flag 2 criteria at the K-Area and Par Pond Sewage Sludge Application Sites. In the KSS well series, the field measurement for alkalinity ranged as high as 26 mg/L in well KSS 1D. Alkalinity measurements were zero in the PSS wells. Historical and current water-level elevations at the K-Area and Par Pond Sewage Sludge Application Site indicate that the groundwater flow directions are south to southwest (SRS grid coordinates).

As part of this involvement Solar intends to design and commercialize a unique gas turbine system that promises high cycle efficiencies and low exhaust emissions. This engine of approximately 12-MW will be targeted for the dispersed power markets both urban and rural. Goals of 50% thermal efficiency and 8 parts-per-million by volume (ppmv) nitrogen oxide emissions were established. Reliability, availability, and maintainability (RAM) will continue to be the most important factors in the competitive marketplace. The other major goal adopted was one of reducing the cost of power produced by 10%. This reduction is based on the cost of power (COP) associated with today`s engines that lie in the same horsepower range as that targeted in this study. An advanced cycle based on an approximation of the Ericsson Cycle was adopted after careful studies of a number of different cycles. This advanced intercooled, recuperated engine when fired at 2450{degree}F will be capable of meeting the 50% efficiency goal if the cooling air requirements do not exceed 7% of the total air flow rate. This latter qualification will probably dictate the use of ceramic parts for both the nozzle guide vanes and the turbine blades. Cooling of these parts will probably …

This report is a recommendation from the Spokane Tribe to the Northwest Power Planning Council (NPPC) for partial mitigation for the extensive wildlife and wildlife habitat losses on the Spokane Indian Reservation caused by the construction of Grand Coulee Dam. NPPC`s interim wildlife goal over the next 7 years for the Columbia hydropower system, is to protect, mitigate and enhance approximately 35% basin wide of the lost habitat units. Grand Coulee Dam had the greatest habitat losses of any Dams of the Wildlife Rule.

The success of the National Synchrotron Light Source is based, in large part, on the size of the user community and the diversity of the scientific and technical disciplines represented by these users. As evidence of this success, the VUV Ring has just celebrated its 10th anniversary and the X-ray Ring will do the same in 1995. In order to enhance this success, the NSLS User`s Manual: Guide to the VUV and X-Ray Beamlines - Fifth Edition, is being published. This Manual presents to the scientific community-at-large the current and projected architecture, capabilities and research programs of the various VUV and X-ray beamlines. Also detailed is the research and computer equipment a General User can expect to find and use at each beamline when working at the NSLS. The Manual is updated periodically in order to keep pace with the constant changes on these beamlines.

The effect in ambient air the tensile and fatigue behavior of an Fe{sub 3}Al, Cr type intermetallic alloy is examined as a function of test temperature. Hydrogen due to moisture in the air is found to be a major cause of embrittlement. Rates and mechanisms of observed embrittlement appear to be temperature dependent. In addition, the alloy was found to have no notch sensitivity.

This report provides a summary of activities, by the DMEC-1 Limited Partnership on the PCFB Repowering Project from project initiation in August 1991 through December 1992. The DMEC-1 project will demonstrate ``First Generation`` PCFB technology and will result in an existing steam turbine being repowered with steam from a PCFB boiler. Exhaust gases from the PCFB boiler will be expanded through a gas turbine to provide additional power output. The preliminary design is progressing. As the design is refined and modified, cost and schedule baselines will be updated. Environmental information has been obtained and submitted to The Department of Energy (DOE) with no obvious problems or concerns identified. Testing analysis and evaluations of systems continue. A key feature of design verification testing has been and will continue to be the testing of ceramic barrier filtration technologies including the Asahi Advanced Ceramic Tube Filter (ACTF) and Westinghouse`s Candle Filter. At the time of this report testing has been completed on the Asahi ACTF and tests have been initiated on the Westinghouse filters. In general terms, the Asahi design was successful in reducing the outlet dust loading to required levels but certain problems were encountered which led to some premature ceramic tube …

The ARM goal is to help improve both longwave and shortwave models by providing improved radiometric shortwave data. These data can be used directly to test shortwave model predictions. As will be described below they can also provide inferred values for aerosol and cloud properties that are useful for longwave modeling efforts as well. The current ARM research program includes three tasks all related to the study of shortwave radiation transfer through clouds and aerosol. Two of the tasks involve the assembly of archived and new radiation and meteorological data sets; the third and dominant task has been the development and use of new shortwave radiometric sensors. Archived data from Golden, Colorado, and Albany, New York, were combined with National Weather Service ground and upper air data for testing radiation models for the era when the Earth Radiation Budget Experiment (ERBE) was operational. These data do not include optimum surface radiation measurements; consequently we are acquiring downwelling shortwave, including direct and diffuse irradiance, plus downwelling longwave, upwelling shortwave, and aerosol optical depth, at our own institution, as an additional dataset for ARM modelers.

Phase I research, in which an electrobalance reactor was used to establish the technical feasibility of the regenerable sorbent process, was completed in March 1992 and results have been fully described in earlier quarterly reports. In Phase I, the calcination and carbonation characteristics of three calcium sorbents were studied as a function of calcination and carbonation temperature and pressure, mol fraction CO{sub 2} in the carbonation gas, and carbonation background gas composition. Desirable reaction conditions required for high reactivity and good sorbent durability were determined. Multicycle tests consisting of as many as ten complete calcination and carbonation cycles were completed. Indirect evidence which suggested that the water-gas shift reaction occurred simultaneously with CO{sub 2} removal was found. Occurrence of the simultaneous reactions created the possibility of a direct one-step process for the manufacture of hydrogen from coal-gas while at the same time separating a concentrated stream of CO{sub 2}. The concentrated CO{sub 2} stream could be quite significant if, in the future, environmental regulations restrict atmospheric CO{sub 2} emissions.

At the Nevada Test Site (NTS), where radionuclide contamination is found in surface soils, there is potential for water erosion to move radionuclides beyond the boundaries of controlled areas and into channels cut by infrequent storms. This loss of control and the increased risk of further movement are issues which require the development of a method for the quantitative monitoring of contamination and calculation of the radionuclide-movement rate. In this report the authors develop a method which is used to measure the amount and rate of movement of americium-241 ({sup 241}Am) in a storm channel, and which offers special features for establishment of baseline concentrations. This method was applied to the standing problem of the erosion of the plutonium contaminated {open_quotes}ground zero{close_quotes} area of site {open_quotes}11D{close_quotes} in Area 11 of NTS. By establishing {sup 241}Am concentrations in the storm channel, the concentrations of {sup 239+240}Pu can also be calculated using a previously determined {sup 239+240}Pu/{sup 241}Am ratio from soil samples collected in Area 11. The method utilizes systematic field surveys with a field instrument for detection of low-energy radiation (FIDLER), and provides a computational method which, when validated, could become a standard procedure for monitoring radionuclide movement in the washes …

Energy Division`s mission is to provide innovative solutions to energy and related Issues of national and global importance through interdisciplinary research and development. Its goals and accomplishments are described in this annual progress report for FY 1992. Energy Division`s total expenditures in FY 1992 were $42.8 million.

ICF Resources` project, entitled {open_quotes}State and National Energy and Environmental Risk Analysis Systems for Underground Injection Control{close_quotes} includes two primary tasks (development of state and national systems respectively) and a technology transfer element. The state system was designed to assist states with data management related to underground injection control (UIC). However, during the current period, external changes (primarily pending regulatory changes at the federal level) have made the risk assessment protocol aspect of the state system of increased importance relative to data management. This protocol would assess the relative risk of groundwater contamination due to UIC activities in various areas of the state. The risk assessment system could be used to assist states in allocating scarce resources and potentially could form the analytical basis of a state variance program to respond to pending federal regulatory changes. Consequently, a substantial portion of the effort to date has been focused on this aspect of the project, The national energy and environmental risk analysis system (EERAS) is designed to enhance DOE`s analytical capabilities. This concept will be demonstrated using UIC data. The initial system design for EERAS has been completed but may be revised based on input from DOE and on the pending …

DNA, the genetic blueprint, has the remarkable property of encoding its own repair following diverse types of structural damage induced by external agents or normal metabolism. We are studying the interplay of DNA damaging agents, repair genes, and their protein products to decipher the complex biochemical pathways that mediate such repair. Our research focuses on repair processes that correct DNA damage produced by chemical mutagens and radiation, both ionizing and ultraviolet. The most important type of DNA repair in human cells is called excision repair. This multistep process removes damaged or inappropriate pieces of DNA -- often as a string of 29 nucleotides containing the damage -- and replaces them with intact ones. We have isolated, cloned, and mapped several human repair genes associated with the nucleotide excision repair pathway and involved in the repair of DNA damage after exposure to ultraviolet light or mutagens in cooked food. We have shown that a defect in one of these repair genes, ERCC2, is responsible for the repair deficiency in one of the groups of patients with the recessive genetic disorder xeroderma pigmentosum (XP group D). We are exploring ways to purify sufficient quantities (milligrams) of the protein products of these and …
