The Tasks of this project are to: Task 1--complete implementation of a Risk Based Data Management System (RBDMS) in the states of Alaska, Mississippi, Montana, and Nebraska; and Task 2--conduct Area of Review (AOR) workshops in the states of California, Oklahoma, Kansas, and Texas. In general, Task 1 provides assistance to the named states with converting data from existing data management systems where applicable; coding and internal testing of the RBDMS; preparing documentation, training, and technology transfer; plus project management. Development of RBDMS in the first grouping of states (AK, MS, MT, and NB) is complete. The paper describes the RBDMS features, continued implementation of the RBDMS and future RBDMS workshops. RBDMS includes comprehensive well information for both producing and injection well types. The purpose of AOR workshops is to acquaint state agency and industry personnel with the AOR variance methodology that has been developed and to seek input from the attendees concerning application of variance methods to injection fields in the state. Workshops have been successfully completed in California and Oklahoma. The Kansas and Texas workshops are tentatively scheduled to take place in November.

The end of the cold war has resulted in excess PCMs from nuclear weapons and associated production facilities. Consequently, the US government has undertaken studies to determine how best to manage and dispose of this excess material. The issues include (a) ensurance of domestic health, environment, and safety in handling, storage, and disposition, (b) international arms control agreements with Russia and other countries, and (c) economics. One major set of options is to convert the PCMs into glass for storage or disposal. The chemically inert characteristics of glasses make them a desirable chemical form for storage or disposal of radioactive materials. A glass may contain only plutonium, or it may contain plutonium along with other radioactive materials and nonradioactive materials. GMODS is a new process for the direct conversion of PCMs (i.e., plutonium metal, scrap, and residues) to glass. The plutonium content of these materials varies from a fraction of a percent to pure plutonium. GMODS has the capability to also convert other metals, ceramics, and amorphous solids to glass, destroy organics, and convert chloride-containing materials into a low-chloride glass and a secondary clean chloride salt strewn. This report is the initial study of GMODS for vitrification of PCMs as …

The Forest Service currently sells timber by (a) planning and preparing the sale, (b) offering the sale, usually at an oral auction, and (c) administering the timber harvest. Many of the concerns about the timber program have focused on harvest administration, because purchasers have incentives to minimize their costs and to remove only those logs whose value for products exceeds the price paid to the Forest Service. Some critics suggest that this, together with an alleged "timber bias" and other inappropriate incentives, has contributed to environmental damages (e.g., deteriorating forest health), poor fiscal performance (e.g., below-cost timber sales), and a lack of accountability (e.g., timber theft). Possible legislative changes to the timber sale system are being considered by various interest groups and Members of Congress.

The objective of this project is to develop a comprehensive, interdisciplinary, and quantitative characterization of a fluvial-deltaic reservoir which will allow realistic inter-well and reservoir-scale modeling to be constructed for improved oil-field development in similar reservoirs world-wide. The geological and petrophysical properties of the Cretaceous Ferron Sandstone in east-central Utah will be quantitatively determined. Both new and existing data will be integrated into a three-dimensional representation of spatial variations in porosity, storativity, and tensorial rock permeability at a scale appropriate for inter-well to regional-scale reservoir simulation. Results could improve reservoir management through proper infill and extension drilling strategies, reduction of economic risks, increased recovery from existing oil fields, and more reliable reserve calculations. Transfer of the project results to the petroleum industry is an integral component of the project. Technical progress this quarter is divided into regional stratigraphy, case studies, stochastic modeling and fluid-flow simulation, and technology transfer activities. The regional stratigraphy of the Ferron Sandstone outcrop belt is being described and interpreted. Detailed geological and petrophysical characterization of the primary reservoir lithofacies typically found in a fluvial-dominated deltaic reservoir, is continuing at selected case-study areas. Interpretations of lithofacies, bounding surfaces, and other geologic information are being combined with permeability …

The objectives of this quarterly report are to summarize the work conducted under each task during the reporting period July-September 1995, and to report all technical data and findings as specified in the {open_quotes}Federal Assistance Reporting Checklist{close_quotes}, The main objective of this project is the transfer of technologies, methodologies, and findings developed and applied in this project to other operators of Slope and Basin Clastic Reservoirs. This project will study methods to identify sands with high remaining oil saturation and to recomplete existing wells using advanced completion technology. The identification of the sands with high remaining oil saturation will be accomplished by developing a deterministic three dimensional (3-D) geologic model and by using a state of the art reservoir management computer software. The wells identified by the geologic and reservoir engineering work as having the best potential will be logged with a pulsed acoustic cased-hole logging tool. The application of the logging tools will be optimized in the lab by developing a rock-log model. The wells that are shown to have the best oil production potential will be recompleted. The recompletions will be optimized by evaluating short radius and ultra-short radius lateral recompletions.

Our project deals with the investigation of a new class of catalysts for processing coal liquids. The catalysts are supported carbides and nitrides of transition metals. These compounds are unique because they have properties similar to those of the precious metals, but are resistant to sulfur. Because they have high hydrogenation activity in the presence of sulfur, they are ideal for coal processing. For our initial work we have decided to start with unsupported carbides and nitrides in order to identify the best possible composition for work with supported catalysts. The research includes synthesis, characterization, and testing of the compounds.

As a possible alternative design approach for the 5 MW Pulsed Spallation Neutron Source (PSNS), the use of an intermediate energy Linac, in conjunction with two accumulator rings has been studied. The lower final beam energy necessitates the use of higher beam current. This disadvantage is greatly offset by the use of dc rings, reducing by an order of magnitude the RF requirements, simplifying greatly the ring magnets and associated power supplies, and eliminating the use of aperture demanding, impedance compensated, ceramic chambers. The reduced magnet/magnet power supply cost and reduction of ring beam energy, permits greater sophistication in ring lattice structure design, easing the beam injection configuration and permitting greater control over localizing unavoidable beam loss.

Inelastic-incoherent-neutron scattering can be a valuable nanostructural probe of H{sub 2}-doped porous materials, provided the spectral peaks can be interpreted in terms of crystal-field-split hydrogen-molecule energy levels, which represent a signature of the local symmetry. Inelastic-neutron-scattering measurements as well as extensive theoretical analyses have been performed on stage-2 Rb-intercalated graphite (Rb-GIC), with physisorbed H{sub 2}, HD, and D{sub 2}, a layered porous system with abundant spectral peaks, to assess whether the crystal-field-state picture enables a quantitative understanding of the observed structure. Potential-energy surfaces for molecular rotational and translational motion, as well as the intermolecular interactions of hydrogen molecules in Rb-GIC, were calculated within local-density-functional theory (LDFT). Model potentials, parameterized using results of the LDFT calculations, were employed in schematic calculations of rotational and translational excited state spectra of a single physisorbed H{sub 2} molecule in Rb-GIC. Results of the analysis are basically consistent with the assignment by Stead et al. of the lowest-lying peak at 1.4 meV to a rotational-tunneling transition of an isotropic hindered-rotor oriented normal to the planes, but indicate a small azimuthal anisotropy and a lower barrier than for the isotropic case. Based on the experimental isotope shifts and the theoretically predicted states, they conclude that spectral …

The author addresses the problem of tracking the spin of particles in a synchrotron. To do this he looks at the machine as a series of elements joined together, and derives matrix equations to represent the spin motion through each element.
