This document provides a discussion of the technical progress on DOE/PETC project number DE-AC22-92PC91338, {open_quotes}High Efficiency SQ Removal Testing{close_quotes}, for the time period 1 October through 31 December 1993. The project involves testing at six 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 upgrades to be evaluated mostly involve using additives in the FGD systems. The {open_quotes}base{close_quotes} project involved testing at the Tampa Electric Company Big Bend station. All five potential options to the base program have been exercised by DOE, involving testing at the Hoosier Energy Merom Station (Option 1), the Southwestern Electric Power Company Pirkey Station (Option 11), the PSI Energy Gibson Station (Option III), the Duquesne Light Elrama Station (Option IV) and the New York State Electric and Gas Company Kintigh Station (Option V). As of December 1993, testing has been completed for the base project and for Options I and II, has begun but is only partly completed for Options III and IV, and has not yet begun for Option V. The remainder of this document is divided into four sections. Section 2, Project Summary, provides …

The general objectives are to (1) to identify and develop gelled polymer systems which have potential to improve reservoir conformance of fluid displacement processes, (2) to determine the performance of these systems in bulk and in porous media, and (3) to develop methods to predict the capability of these systems to recover oil from petroleum reservoirs. This work focuses on three types of gel systems -- an aqueous polysaccharide (KUSP1) system that gels as a function of pH, the chromium(III)-polyacrylamide system and the aluminum citrate-polyacrylamide system. Laboratory research is directed at the fundamental understanding of the physics and chemistry of the gelation process in bulk form and in porous media. This knowledge will be used to develop conceptual and mathematical models of the gelation process. Mathematical models will then be extended to predict the performance of gelled polymer treatments in oil reservoirs. Results to date are summarized.

While many aspects of matter are unpredictable from basic principles, there are some that are susceptible to empirical descriptions which can be quite accurate and beautiful. One such example from the field of ``Nuclear Matter Under Extreme Conditions`` is the distribution of the number of particles produced, or alternatively, of the energy carried by these particles, in energetic collisions of atomic nuclei. The present work consists of a series of published scientific papers on measurements of the distribution of particles produced, or the energy carried by these particles, in collisions of various nuclei, spanning more than a decade of research. Due to the unpredictability of the theory, the work includes empirical studies of the regularity of the measured distributions from which significant knowledge is gained. The aesthetics of this subject derives from the physical beauty of the measured curves, the characteristic changes of shape with different species of nuclei, and the deep understanding obtained by the use of a simple and elegant mathematical function to describe the data.

Several FEA analyses of the STAR EM support rings have been performed. The original design was a continuous ring with a ``C`` channel cross section. These rings were 2-3/4 inch thick with the center rings being only 1-3/4 inch thick. Based on the early analysis of these rings, it was determined that a continuous ring with a solid cross section should be used. A thermal and mechanical analysis of both cross sections was performed. Because of symmetry, only half of the rings were modeled. The gravity load of the EM was applied to the ring by a rigid bar that extended radially from the location of the Thompson rails on the ring to the center of gravity of the EM module. In this paper the authors will first describe the analysis of the rings with the ``C`` channel cross section. The mechanical and thermal analysis of the thick 2-3/4 inch ring will be described, followed by the mechanical and thermal analysis of the thinner 1-3/4 inch ring. In the second section, the analysis of the rings with the solid cross section will be described. Once again the thermal and mechanical analysis of the thicker 2-3/4 inch ring will be first …

A high-resolution x-ray spectrometer was constructed and fielded at the National Laser Users Facility at the Laboratory for Laser Energetics, University of Rochester. The spectrometer was attached to a streak camera and time-resolved x-ray spectra recorded. The targets were irradiated by the 24-beam Omega laser and consisted of CH microballoons filled with DD, argon, and xenon. The x-ray spectral lines from Ar and Xe were used to determine the plasma properties of the compressed core region.

The objective for this research is to optimize the design and operation of the bench scale batch reactor (STBR) for coat liquefaction at short contact times (0.01 to 10 minutes). This reactor is simple and low enough in cost to serve as a suitable replacement for the traditional tubing-bomb reactors for coal liquefaction and other high-pressure, high-temperature reaction studies. The details of the reactor system are shown in Figure 2. The heating bath used is a Techne IFB-52 industrial fluidized sand bath, which maintains a reaction temperature of {plus_minus}2{degrees}C. The 30 cm{sup 3} reactor is capable of containing up to 17 MPa (2500 psi) pressure at temperatures up to 550{degrees}C. The tubing used for preheater and precooler was 1/4in. 316 stainless steel with wall thickness of 0.035in. The lengths of the preheater and precooler are selected based on the particular process being studied. Since a gas (e.g. hydrogen or nitrogen) is bubbled through the reaction mixture under pressure and out through a letdown valve, a small water cooled condenser above the reactor before the let-down valve is added to avoid loss of solvent or other low boiling components. Coal liquefaction runs are made by preparing slurries of coal in reagent …

EPICS release 3.11 is now ready for user testing. A person who wants to set up a simplified application environment to boot an IOC and create databases using R3.11 should follow the directions in Appendix B, page 27, of the EPICS Source/Release Control Manual, Sept. 20, 1993. The R3.11 EPICS path at ANL/APS is /net/phebos/epics/R3.11 so the command to get the new release is /net/phebos/epics/R3.11/Unix/share/bin/getrel /net/phebos/epics/R3.11. An existing R3.8 short form report can be copied to this new directory and used to create a database. ANL/APS is currently testing an Application Developers Source/Release control system. It is not yet ready for general distribution. Attached are the EPICS R3.11 release notes.

The National Storage Laboratory (NSL) was organized to investigate, demonstrate, and commercialize high-performance hardware and software storage technologies that promise to remove network computing bottlenecks and provide critically needed new storage systems functionality. This paper briefly outlines the goals, collaboration and current status of the NSL.
