This report explains the method chosen to phase match cables, it`s accuracy and the effects of mismatched cables on the position output of the Linac Beam Position Module.

Relatively simple models are presented to simulate close-in atmospheric dispersion, explosive releases, and particle deposition. Close-in generally refers to distances less than 50 m downwind from the source. These models assume simple gas dispersion (no chemical reactions, neutral buoyancy) and that particles behave as a gas expect they can be removed from the plume by a simple, deposition-velocity mechanism. These models have been combined into a QuickBASIC program (INEXPLC.BAS) and its PC executable form (INEXPLC.EXE). These programs, along with sample input and output files, are available from the author.

This paper examines the factors that threaten the future of the Russian Federation (RF). The observations are based on a study that focused on eight republics: Mordova, Udmurtia, Tatarstan, Mari El, Bashkortostan, Kabardino-Balkaria, Buryatia, and Altay Republic. These republics were selected for their geographic and economic significance to the RF. Tatarstan, Bashkortostan, Udmurtia, and Mari El are located on important supply routes, such as the Volga River and the trans-Siberian railroad. Some of these republics are relatively wealthy, with natural resources such as oil (e.g., Tatarstan and Bashkortostan), and all eight republics play significant roles in the military-industrial complex. The importance of these republics to the RF contrasts to the relative insignificance of the independence-minded Northern Caucasus area. The author chose not to examine the Northern Caucasus region (except Kabardino-Balkaria) because these republics may have only a minor impact on the rest of the RF if they secede. Their impact would be minimized because they lie on the frontiers of the RF. Many Russians believe that {open_quotes}it might be best to let such a troublesome area secede.{close_quotes}

The X-Ray Laser Program has evolved from a design effort focusing on developing a Strategic Defense Initiative weapon that protects against Soviet ICBMs to a scientific project that is producing new technologies for industrial and medical research. While the great technical successes and failures of the X-ray laser itself cannot be discussed, this article presents the many significant achievements made as part of the X-ray laser effort that are now being used for other applications at LLNL.

Self-lubricating composites consist of at least one structural (matrix) phase and at least one phase to provide lubrication. Modeling the behavior of such composites involves ascertaining the frictional contributions of each constituent phase under varying conditions of lubricating films coverage. The ORNL friction microprobe (FMP), a specialized microcontact tribometer, was used to investigate the frictional behavior of both matrix and lubricant phases to support the development of self-lubricating, surfaces. Polished CVD-silicon carbide deposits and silicon wafers were used as substrates. The wafers were intended to simulate the thin silica films present on SiC surfaces at elevated temperature. Molybdenum disulfide, in both sputtered and burnished forms, was used as the model lubricant. The effects of CVD-SiC substrate surface roughness and method of lubricant film deposition on the substrate were studied for single passes of a spherical silicon nitride slider (NBD 200 material). In contrast to the smooth sliding exhibit by burnished, films, sputtered MoS{sub 2} surfaces exhibited marked stick-slip behavior, indicating that the frictional behavior of solid lubricating coatings can be quite erratic on a microscale, especially when asperity contacts are elastically compliant.

This report discusses the following topics: Yaug collider detector program; E-791: continued study of heavy flavors at TPL; Hadroproduction of charm and beauty; Search for composite objects produced in relativistic heavy ion collisions; and high energy physics computer facility.

The Largest US Oil and Gas Fields is a technical report and part of an Energy Information Administration (EIA) series presenting distributions of US crude oil and natural gas resources, developed using field-level data collected by EIA`s annual survey of oil and gas proved reserves. The series` objective is to provide useful information beyond that routinely presented in the EIA annual report on crude oil and natural gas reserves. These special reports also will provide oil and gas resource analysts with a fuller understanding of the nature of US crude oil and natural gas occurrence, both at the macro level and with respect to the specific subjects addressed. The series` approach is to integrate EIA`s crude oil and natural gas survey data with related data obtained from other authoritative sources, and then to present illustrations and analyses of interest to a broad spectrum of energy information users ranging from the general public to oil and gas industry personnel.

Water and acid absorption tests of samples of a proposed replacement to current polyethylene foam used as fill material on the FB-Line cation columns have been completed. Water and nitric acid solution absorption of up to 4 volume percent was observed over approximately a 4 month period of time. Because of the nuclear safety implications, liquid absorption of a replacement fill material must be low. EthafoaM{trademark} 220 extruded polyethylene, a product available from Dow Chemical Company appears to be a good candidate material for replacement of the existing fill material. Establishment of 5 volume percent solution absorption specification appears to be both reasonable and achievable for a replacement foam, provided it is acceptable to nuclear safety personnel.

Due to the commitment and participation of more than 100 professionals from site environmental coordinators, customer improvements and total quality are being incorporated into the Environmental Implementation Plan (EIP). The EIP is now a living document that communicates an overview of site environmental programs and the facility plans that are designed to protect the environment and meet changing regulatory requirements. Continuous improvement of environmental programs is enhanced through planned quarterly self-assessments during the {open_quotes}Reflections{close_quotes} process. Through the sharing of noteworthy practices, lessons learned, and ideas for improvement, the EIP provides a framework for environmental professionals to promote cost effective solutions and program improvements through teamwork and communication. These efforts were initiated by the Central Environmental Committee Executive Committee (CECEC) and developed and coordinated by the EIP subcommittee. The EIP revision process is the baseline for a continuous improvement cycle. Although the EIP is a Westinghouse Savannah River Company (WSRC) document, the environmental-planning process involves and will benefit all site contractors. Together, we are committed to a {open_quotes}Partnership in Environmental Excellence.{close_quotes}

Work this quarter included equipment installation, shakedown testing, and the beginning of the detailed testing program. With the exception of ongoing Task 4: Sample Characterization, Tasks 1 through 8 are now complete. Task 10: Detailed Testing and Task 12: Sample Analysis began this quarter and will consume all available time during the 5th quarter. Installation and testing of the process equipment, mechanical systems, as well as the electrical systems were completed. The shakedown process uncovered several necessary modifications to the circuit which were subsequently completed. Most of the changes concerned piping and valving modifications which allowed for better material flow and sampling. The circuit was operated with coal to determine the time for each unit to reach steady state. The primary objective of the proposed work is to design, install, and operate an advanced fine coal processing circuit combining the Microcel{trademark} and Multi-Gravity-Separator (MGS) technologies. Both of these processes have specific advantages as stand-alone units. For example, the Microcel column effectively removes ash-bearing mineral matter, while the MGS efficiently removes coal-pyrite composites.

The Interactive, Computer-Enhanced, Remote Viewing System (ICERVS) is designed to provide a reliable geometric description of a robotic task space in a fashion that enables robotic remediation to be carried out more efficiently and economically that with present systems. The key elements are a robust way to store empirical data and a friendly user interface that provides an operator with timely access to all that is known about a scene. ICERVS will help an operator to analyze a scene and generate additional geometric data for automating significant portions of the remediation activity. Features that enable this include the following: storage and display of empirical sensor data; ability to update segments of the geometric description of the task space; side-by-side comparisons of a live TV scene and a computer generated view of the same scene; ability to create and display computer models of perceived objects in the task space, together with textual comments; and easy export of data to robotic world models for robot guidance. Phase 1 of this project was essentially completed in the month of June. Phase 1 (Level III) of this project focuses on the development of the Data Library, which contains the geometric data about the task …

The reverse osmosis (RO) system at the Effluent Treatment Facility (ETF) at the Savannah River Site, Aiken, South Carolina has experienced fouling from trace quantities of inorganics (Al, Fe, and Si) and l.E5-l.E7/ml bacteria. The bacteria are primarily produced in an upstream Hg-removal resin bed/activated carbon bed process. The bacteria adhere to the colloidal inorganics that are in the membrane feed at their solubility limits (having been precipitated and removed upstream by a ceramic microfilter system). The resulting bacterial/inorganic foulant adheres to the membrane surface and results in high feed pressures and poor salt rejection. The feed pressure increases because the membrane system at the ETF is designed to produce a constant rate of treated water, or permeate. This is accomplished by increasing the membrane feed pressure whenever permeate flow drops. These performance losses have been attributed to bacteria present in the feed, and several potential solutions have been proposed and demonstrated here at the Savannah River Technology Center (SRTC). Advanced hybrid plate-and-frame modules have been developed that increase the applicability of membrane systems by using hydrodynamics rather than pretreatment to prevent membrane fouling.

Environmental projects, issues, and programs have become increasingly important to the Westinghouse Savannah River Company (WSRC) management and the Department of Energy (DOE). A compliance-tracking system has been developed to monitor environmental requirements and commitments because they have become increasingly complex and numerous. An Environmental Data Management (EDM) steering committee was formed in October 1987 to develop computer system solutions to environmental needs. The committee`s main objective is to coordinate, within SRS divisions, the separate efforts that have been or are being developed to meet regulatory requirements and specific programmatic goals. The Environmental and Graphical Information Systems (E&GIS) Program was recently developed to establish a more formal organizational structure and enhance the coordination of geographical information systems (GIS) and environmental data management (EDM) activities at SRS. The general strategy of the program is to establish a coordination focal point for GIS and EDM activities, to provide for the integration of the several environmental and graphical information systems which exist mostly in stand-alone arrangements, and to guide the development of data management and geographical information applications in order to achieve alignment with Site computing architecture and standards. The E&GIS Program will enhance the Site`s ability to respond to data requirements in …

Measurements of the transverse dependence of the flux on the symmetry plane were obtained on a series of endpacks mounted on a Main Injector prototype dipole. From these flux measurements, we determined the endfield shape, expressed in terms of normal harmonics, up to 14-pole. We describe the measurement and analysis procedure, and present the results for all endpacks that were tested. The final endpack (number 10) has a sextupole, normalized to the body, of +0.167 {plus_minus} .072 units, and the relative field shape deviates by {lt} 1.2 units relative to the on-axis field strength over the range {vert_bar}x{vert_bar} {lt} 2.0{double_prime}. These measurements indicate that Endpack 10 meets the requirements for the Main Injector dipole.

Samples were collected during the A/M Area Crouch Branch (Cretaceous) Aquifer Characterization (Phase I) Program. The samples were analyzed for chlorinated VOCs by the Savannah River Technology Center (SRTC) and MicroSeeps Ltd. All samples were sealed in the field immediately upon retrieval of the core and subsampling. A total of 113 samples locations were selected for analysis. The Environmental Sciences Section (ESS) of SRTC analyzed all locations in duplicate (226 samples). MicroSeeps Ltd was selected as the quality assurance (QA) check laboratory. MicroSeeps Ltd analyzed 40 locations with 4 duplicates (44 samples). The samples were collected from seven boreholes in A/M Area in the interval from 200 feet deep to the total depth of the boring (360 feet deep nominal); samples were collected every 10 feet within this interval. The sampling zone corresponds approximately to the Crouch Branch Aquifer in A/M Area. The overall A/M Area Crouch Branch Aquifer characterization objectives, a brief description of A/M Area geology and hydrology, and the sample locations, field notes, driller lithologic logs, and required procedural documentation are presented in WSRC (1993).

The superconducting magnets in Fusion Reactors are subjected to pulsed, nuclear, and resistive heating. The thermo-hydraulic response of the helium forced-flow cooled conductors to the various heat sources is critical to magnet design and performance. Recently developed computer codes allow accurate modeling of conductor response and have been used as an aid to design of the toroidal field (TF) magnets for the Tokamak Physics eXperiment (TPX). The authors present results of design studies that determine the trade-off between double- and single-pancake helium-flow configurations.

This report summarizes the US Department of Energy`s (DOE) cultural resource studies that were undertaken in support of the DOE`s Uranium Mill Tailings Remedial Action (UMTRA) Project in the state of Colorado for the period of October 1, 1991, through September 30, 1992. This report fulfills the DOE`s obligation to provide an annual report to the state of Colorado on the status and results of cultural resource studies conducted during the above period of record. This requirement is stated in a programmatic memorandum of agreement executed between the DOE, the Advisory Council on Historic Preservation, and the Colorado State Historic Preservation Officer in December 1984. Previous reports were based on a calendar year reporting period. However, in order to be more consistent with the programmatic memorandum of agreement, the period of record for this and subsequent annual reports has been changed to the Federal fiscal year. The current status and summaries of 1992 cultural resource surveys are provided for all UMTRA Project sites in Colorado. The sites are Durango, Grand Junction, Gunnison, Maybell, Naturita, Rifle, and Slick Rock.

The objective of this study is to determine, through the collection of grab sampling data, that an in-depth resuspension study should or should not be performed. Currently there is not enough data available to determine if a potential health hazard exists due to resuspended contamination in the tank farms. A detailed resuspension study is currently not justified, because the limited quantity of air sample data collected does not indicate the existence of a potential health hazard.

The presence of potassium or calcium in sol gel catalysts increase the production of C{sub 4} hydrocarbon and that of methane while maintaining high activities. Characterization of catalysts using temperature programmed desorption of carbon dioxide indicates that activity and product distribution over an isosynthesis catalyst depend on its acid-base properties. Low activity was observed for catalysts with very weak basicity, and high oxygenate production for catalysts with strong basicity. An optimum strength of basic sites is crucial to achieve high activity while minimizing the amount of oxygenates. A kinetic model was developed based on the reaction mechanisms, and the simulation from the model produces reasonable fit with the experimental data.
