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.

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.

These measurements indicate that Endpack 10 meets the requirements for the Main Injector dipole.

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.

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.

The protocol is supplemented by notes containing two sorts of information. One category includes references to the appropriate portions of their published papers giving the scientific rationale and experimental basis for important steps. The other category is concerned with the criticality of certain steps and the precision with which they need to be performed. As an aid to investigators, the authors list even ordinary pieces of equipment. Brand names and model numbers are given where it is either important or convenient for readers to know precisely what is used.

Elegant stands for ``Electron Generation and Tracking,`` a somewhat out-of-date description of a fully 6D accelerator program that now does much more than generate particle distributions and track them elegant, written entirely in the C programming language, uses a variant of the MAD input format to describe accelerators, which may be either transport lines, circular machines, or a combination thereof. Program execution is driven by commands in a namelist format. This document describes the features available in elegant, listing the commands and their arguments. The differences between elegant and MAD formats for describing accelerators are listed. A series of examples of elegant input and output are given. Finally, appendices are included describing the post-processing programs.

This directory contains descriptions about each model, including the title, acronym, purpose, followed by more detailed information on characteristics, uses, and requirements. Sources for additional information are identified. Included in this directory are 35 EIA models active as of May 1, 1993. Models that run on personal computers are identified by ``PC`` as part of the acronym. EIA is developing new models, a National Energy Modeling System (NEMS), and is making changes to existing models to include new technologies, environmental issues, conservation, and renewables, as well as extend forecast horizon. Other parts of the Department are involved in this modeling effort. A fully operational model is planned which will integrate completed segments of NEMS for its first official application--preparation of EIA`s Annual Energy Outlook 1994. Abstracts for the new models will be included in next year`s version of this directory.

President Clinton proposed to Prime Minister Miyazawa the idea of a framework for U.S.-Japanese negotiations during their April 13, 1993 meeting in Washington. The two leaders agreed to instruct subordinates to prepare details of such a framework in time for presentation in July in Tokyo when the President would meet with the Prime Minister and the other G-7 leaders at the annual economic summit.

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.

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.

The Short-Term Energy Outlook Annual Supplement (supplement) is published once a year as a complement to the Short-Term Energy Outlook (Outlook), Quarterly Projections. The purpose of the Supplement is to review the accuracy of the forecasts published in the Outlook, make comparisons with other independent energy forecasts, and examine current energy topics that affect the forecasts.

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 …

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 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.

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 …
