The main goal of this contract is to develop a catalyst and technology that will produce iC{sub 4}= directly from coal-derived syngas and that is capable of utilizing a lower (0.5 to 1.0) H{sub 2}:CO ratio. The research will identify and optimize the key catalyst and process characteristics that give improved performance for CO conversion by a non-Fischer-Tropsch process. This report, which is the seventh quarterly report covers the testing of various ZrO{sub 2}-based catalyst systems designed to examine the effects of catalyst preparation and process variables, especially low calcination temperature and mild reaction conditions (low temperatures, low pressure and low space velocity). Testing of solvent-extracted sol-gel ZrO{sub 2} catalysts indicate a decrease in isobutene yield. Lowering the reaction temperature, pressure and space velocity resulted in a small improvement in isobutene yield. Three extended runs demonstrated reasonable catalyst stability. In view of the generally poor isobutene yields, the emphasis in this project will shift to isoalcohol production.

The Site Characterization Plan (SCP) (DOE, 1988) attempted to define surrogate criteria that could be used to establish potential repository performance. These criteria or SCP thermal goals were developed from knowledge existing at the time and, as a reference case, emphasized performance for waste emplacement in a vertical borehole. Since that time, new knowledge has become available and some additional analyses of thermal loading have been performed. Additionally, other emplacement modes such as in-drift emplacement are being considered to accommodate larger waste packages. New concepts such as ``extended hot`` are also being considered as possible methods to achieve improved waste isolation. Thus it became clear that the thermal goals established in the SCP should be reevaluated. A Working Group was formed to reassess the SCP thermal goals to determine whether each goal was still valid, if there were goals that needed to be added, and what if any effort was needed to reduce the uncertainty associated with a particular goal. The objectives of the effort were to: (1) provide thermal goals that would support the FY 1993 Thermal Loading Systems Study; (2) help focus the planned testing and analysis efforts; and (3) acquire data that potentially could be used to …

The pyrolysis of methane in the absence of a quench was studied at temperatures between 900 and 1050{degrees}C and methane flows of 80--200 Scc/min. At 1050{degrees}C and a methane flow rate of 100 Scc/minute, methane conversion ranged between 15--19% with the major products being benzene, acetylene, and ethylene. The benzene molar selectivity was ca. 50%, corresponding to molar yield of ca. 7.5--10%. The reaction resulted in the formation of visible amounts of solid carbon, particularly at 1050{degrees}C. The resulting solid consisted partly of carbon and partly of a yellowish tar-like material which was soluble in toluene and contained various heavy hydrocarbons and polyring aromatics.

KM, Knob Manager, is a tool which enables the user to use the SUNDIALS knob box to adjust the settings of the control system. The followings are some features of KM: dynamic knob assignments with the user friendly interface; user-defined gain for individual knob; graphical displays for operating range and status of each process variable is assigned; backup and restore one or multiple process variable; save current settings to a file and recall the settings from that file in future.

This project is concerned with the over-production of ligno-cellulolytic enzymes which are relevant to the paper-pulp industry and agricultural community. Since ligno-cellulosics are components of wood, the project involves the forest, a renewable energy resource. Attention is focused on the following: over-production of polyphenol oxidase; establishment of the route of polyphenol oxidase secretion; regulation of polyphenol oxidase secretion; purification of extracellular oxidase.

The overall objectives of this work are: (i) to investigate the importance of various qualities and quantities of data on the optimization of waterflooding performance; and (ii) to study the application of newly developed geostatistical techniques to analyze available production data to predict future proposals of infill drilling. The study will be restricted to Pennsylvanian sandstone reservoirs commonly found in Oklahoma.

In our second year of funding we began the testing phase of a number of new classes of lubricants. Three different testing collaborations have already begun and a fourth one is In the works with Dr. Stephen Hsu of the National Institute of Standards and Technology. Dr. Hsu also plans to test some of the same materials for us that Shell Development is studying. With Dr. Bill Jones of NASA, we are studying the effects of branching an high temperature lubricant properties in perfluoropolyethers, Initially Bill Jones is comparing the lubrication and physical properties of perfluorotetraglyme and the following two spherical perfluoropolyethers, Note that one contains a fluorocarbon chain and the other one contains a fluorocarbon ether chain. The synthesis of these was reported in the last progress report. With Professor Patricia Thiel of Iowa State University, we are working on studies of perfluoromethylene oxide ethers and have prepared a series of four of these polyethers to study in collaboration with her research group. These perfluoromethylene oxide ethers have the best low temperature properties of any known lubricants. Thiel's group is studying their interactions with metals under extreme conditions. Thirdly, we have also begun an Interaction with W. August Birke …

The Nuclear Physics group at the University of Tennessee, Knoxville is involved in several aspects of heavy-ion physics including both nuclear structure and reaction mechanisms. While our main emphasis is on experimental problems involving heavy-ion accelerators, we have maintained a strong collaboration with several theorists in order to best pursue the physics of our measurements. During the last year we have led several experiments at the Holifield Heavy Ion Research Facility and participated in others at Argonne National Laboratory. Also, we continue to be very active in the collaboration to study ultra-relativistic heavy ion physics utilizing the SPS accelerator at CERN in Geneva, Switzerland and in a RHIC detector R D project. Our experimental work is in four broad areas: (1) the structure of nuclei at high angular momentum, (2) heavy-ion induced transfer reactions, (3) the structure of nuclei far from stability, and (4) ultra-relativistic heavy-ion physics. The results of studies in these particular areas will be described in this document in sections IIA, IIB, IIC, and IID, respectively. Areas (1), (3), and (4) concentrate on the structure of nuclear matter in extreme conditions of rotational motion, imbalance of neutrons and protons, or very high temperature and density. Area (2) …

Direct holographic imaging of biological materials is widely applicable to the study of the structure, properties and action of genetic material. This particular application involves the sequencing of the human genome where prospective genomic imaging technology is composed of three subtechnologies, name an x-ray holographic camera, suitable chemistry and enzymology for the preparation of tagged DNA samples, and the illuminator in the form of an x-ray laser. We report appropriate x-ray camera, embodied by the instrument developed by MCR, is available and that suitable chemical and enzymatic procedures exist for the preparation of the necessary tagged DNA strands. Concerning the future development of the x-ray illuminator. We find that a practical small scale x-ray light source is indeed feasible. This outcome requires the use of unconventional physical processes in order to achieve the necessary power-compression in the amplifying medium. The understanding of these new physical mechanisms is developing rapidly. Importantly, although the x-ray source does not currently exist, the understanding of these new physical mechanisms is developing rapidly and the research has established the basic scaling laws that will determine the properties of the x-ray illuminator. When this x-ray source becomes available, an extremely rapid and cost effective instrument for …

The balance of stable and decaying tracers was incorporated into a latitude-depth ocean circulation model which resolves the major ocean basin and is coupled to an atmospheric energy balance model. The modern distribution of radiocarbon and the analysis of artificial color tracers enabled the census of the deep water masses. We show that good agreement with the observation can be achieved if the surface forcing is modified. The same process could also account for long-term, large-scale changes of the global thermohaline circulation. Uptake rates of carbon are investigated using an inorganic carbon cycle model and performing 2 [times] CO[sub 2]-experiments. We prescribe the industrial evolution of pCO[sub 2] in the atmosphere from 1792 to 1988 and calculate the total flux of carbon into the world ocean. Results are in good agreement with two recent 3-dimensional model simulation. First results using an organic carbon cycle in this model are presented. Changes in the hydrological cycle can stabilize the thermohaline circulation in the Atlantic and enable simulation of climate events resembling the Younger Dryas. By adding the balance of radiocarbon the evolution of its atmospheric concentration is studied during rapid changes of deep ocean ventilation. A resumption of ventilation creates a rapid …

The effect of self-consistency on Hamiltonian systems with a large number of degrees-of-freedom is investigated for the beam-plasma instability using the single-wave model of O'Neil, Winfrey, and Malmberg.The single-wave model is reviewed and then rederived within the Hamiltonian context, which leads naturally to canonical action- angle variables. Simulations are performed with a large (10[sup 4]) number of beam particles interacting with the single wave. It is observed that the system relaxes into a time asymptotic periodic state where only a few collective degrees are active; namely, a clump of trapped particles oscillating in a modulated wave, within a uniform chaotic sea with oscillating phase space boundaries. Thus self-consistency is seen to effectively reduce the number of degrees- of-freedom. A simple low degree-of-freedom model is derived that treats the clump as a single macroparticle, interacting with the wave and chaotic sea. The uniform chaotic sea is modeled by a fluid waterbag, where the waterbag boundaries correspond approximately to invariant tori. This low degree-of-freedom model is seen to compare well with the simulation.

ESME is a computer program to calculate the evolution of a distribution of particles in energy and azimuth as it is acted upon by the radio frequency system of a proton synchrotron. It provides for the modeling of multiple rf systems, feedback control, space charge, and many of the effects of longitudinal coupling impedance. The capabilities of the program are described, and the requirements for input data are specified in sufficient detail to permit significant calculations by an uninitiated user. The program is currently at version 8.0 and extensively modified since the previous user documentation. Changes since the 7.xx versions include a new command and associated parameters for mapping phase space flow lines, new names for a few parameters, and a few new parameters for old commands. Special attention has been given to features relating to calculation of the collective potential and the generation of phase space trajectories including its effects. The VAX-based code management convention has been modified slightly to permit EXPAND pre-compile options to be used in the include files as well as the program source files.

At the request of the former Secretary, an inspection of six classified intelligence and special access program work-for-others projects was conducted. The purpose of this inspection was to evaluate managements, effectiveness regarding these work-for-others projects and included tests for financial integrity and adherence to applicable laws and regulations. Details of the inspection are provided in this report.

Use of ``LDS Moldable`` as a cushion material for future DWPF melters is deemed feasible, because it serves the purpose of reducing the stress in the steel shell to acceptable levels. The assessment is based on the design geometry of the DWPF melter currently undergoing testing.

The authors are developing a next-generation software environment to support large-scale DNA sequencing for the Human Genome Project. The goal is to automate the data flow from its generation by the DNA sequencing hardware to the final reconstructed sequence. Thus, the emphasis is on automation while providing efficient graphical interfaces for interaction with or inspection of the data. A secondary goal is to develop a system flexible enough to support a range of sequencing strategies, including random, and various directed and mixed strategies. The project will result in a software product named the {open_quotes}Genome Reconstruction Manager{close_quotes} (GRM). The authors are presently engaged in the final phase during which they plan to deliver a production quality system to a small number of DNA sequencing laboratories. By the end of the project they will have accomplished the main objectives stated in their original proposal except that GRM will not include all of the analytical capabilities that were planned. The reason for this is that the system proved to be much more complex than originally expected and required more effort to be devoted to system design and implementation. However, the design of GRM anticipates the addition of analytical capabilities and the strategy to …

A project to document the insect species in the upper reaches of Upper Three Runs at the Savannah River site was recently completed. This research was supported by the US Department of Energy under the National Environmental Research Park Program. The work was performed by the Department of Entomology at Clemson University in clemson, SC, by John C. Morse (principal investigator), William R. English and their colleagues. The major output from this study was the dissertation of Dr. William R. English entitled ``Ecosystem Dynamics of a South Carolina Sandhills Stream.`` He investigated selected environmental resources and determined their dynamics and the dynamics of the aquatic invertebrate community structure in response to them.

The primary objectives of this task are to characterize the sludge, to identify any unexpected processing problems, and to demonstrate the ability to make an acceptable glass product. Another objective is to determine the amount of washing that the sludge from Tank 42 requires. The 500 ml glass Sludge Receipt and Adjustment Tank (SRAT) and the 100 L stainless steel SRAT have already been used in the Shielded Cells to demonstrate the process using samples from other tanks. The melter and off-gas system have also been used in the Shielded Cells to vitrify sludge from Tanks 8 & 12 and from Tank 51.

Effect of low-NO{sub x} firing. There was no clear-cut effect on the emission of trace metals or acid gases. The data give marginal evidence for a decreased emission of Cr(VI), which would be a favorable change but is not certain by any means. The effect on aldehydes and ketones cannot be stated because of the loss of samples for baseline conditions; no credible data on these compounds were obtained for baseline conditions. The change in volatile organics appeared to be a reduction in emissions, whereas that for semi-volatiles seemed to be an increase. Inasmuch as low-NO{sub x} firing is sometimes accompanied by large increases in the amount of unburned carbon in the ash, the result for semi-volatiles is more in line with expectation. Effect of the hot-side ESP. As indicated above, the hot-side ESP lowered trace-element emissions to the range roughly from 1 to 5% of the levels found in the inlet gas stream. Not surprisingly, the hot-side ESP had no measurable influence on the emissions of SO{sub x}, HF, and HCl. Quite surprisingly, on the other hand, the ESP seemed to suppress the emission of certain organic substances. Suppression of the emission of formaldehyde is particularly difficult to explain. …

This Task Technical Plan summarizes work required to project the benzene emissions from the Late Wash Facility (LWF) as well as update the benzene, mercury, and NO{sub x} emissions from the remainder of the Defense Waste Processing Facility (DWPF). These calculations will reflect (1) the addition of the LWF and (2) the replacement of formic acid with nitric acid in the melter preparation process. The completed calculations will be used to assist DWPF in applying for the LWF Air Quality Permit.

On March 8, 1990, the Defense Nuclear Facilities Safety Board (DNFSB) issued Recommendation 90-2 to the Secretary of Energy. This recommendation, based upon the DNFSB`s initial review and evaluation of the content and implementation of standards relating to the design, construction, operations, and decommissioning of defense nuclear facilities of the U.S. Department of Energy (DOE), called for three actions: identification of specific standards that apply to design, construction, operation and decommissioning of DOE facilities; assessment of the adequacy of those standards for protecting public health and safety; and determination of the extent to which they have and are being implemented. The purpose of this Implementation Plan is to define the single program for all sitewide and facility 90-2 ES and H Standards Compliance efforts, which will satisfy the HQ Implementation Plan, avoid duplicate efforts, be as simple and achievable as possible, include cost-saving innovations, use a graded approach based on facility hazards and future needs of facilities, and support configuration control for facility requirements. The Defense Waste Processing Facility (DWPF) has been designated a pilot facility for the 90-2 program and has progressed with their facility program ahead of the site-level program. The DWPF, and other Government-Owned Contractor-Operated (GOCO) facilities …

This topical report is the first for the UOP Bench-Scale Co-processing contract. The objective of this contract is to extend and optimize the UOP single-stage, slurry-catalyzed co-processing scheme. UOP co-processing uses a single-stage, slurry-catalyzed scheme in which petroleum vacuum resid and coal are simultaneously upgraded to a high-quality synthetic oil. A highly active, well-dispersed catalyst permits operations at moderate- and high-severity reaction conditions with minimum detrimental thermal reactions. In this process, finely ground coal, petroleum resid, and catalyst are mixed, combined with hydrogen, and then directed to a single-stage reactor, where the simultaneous upgrading of the petroleum resid and coal occurs. The reactor effluent is directed to a series of separators, where a hydrogen-rich gas is recovered and recycled back to the reactor inlet. The balance of the material is sent to a series of separators, where the light gasses, light oil, vacuum gas on (VGO), catalyst, unconverted coal, ash, and residues are recovered. The catalyst is recycled back to the reactor. The UOP co-processing scheme is designed to be integrated into a conventional petroleum refinery. the hydrocarbon products from the co-processing unit will be sent to the refinery for final upgrading to finished products. A major focus of this …

Structural design and analysis and other practical engineering considerations indicate that the 3-point, kinematic chamber support concept in the GEM Technical Design Report should be replaced by a 4-point, {open_quotes}partial{close_quotes} kinematic support design. Detector physics performance may increase due to a resulting decreased mass in the secondary support structure.
