Infill drilling if wells on a uniform spacing without regard to reservoir performance and characterization foes not optimize reservoir development because it fails to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, and carbonate reservoirs in particular. New and emerging technologies, such as geostatistical modeling, rigorous decline curve analysis, reservoir rock typing, and special core analysis can be used to develop a 3-D simulation model for prediction of infill locations.

One reliable and convenient way of processing the cross sections in the resolved energy region is by use of the generalized pole representation, whereby the Doppler-broadening calculation can be carried out rigorously using the analytical approach. So far, its applications have been limited to cases with resonance parameters specified by the Reich-Moore formalism. Although such an approach, in principle, can be extended to all three remaining representations of resolved resonance parameters specified by the ENDF data format, there is no computational tool for handling such a task at present. Given that Breit-Wigner formalisms are probably the most widely used by any evaluated nuclear data library to represent cross sections, a special effort has to be made to convert the single level and multilevel Breit-Wigner resonance parameters to pole parameters. A FORTRAN computer code BW2PR has been developed for this purpose. Extensive calculations have been performed to demonstrate that the proposed method ensures the conservation of the information contained originally in Breit-Wigner resonance parameters. This will make it possible to apply the exact Doppler-broadening method to a larger collection of nuclides.

Ir-0.3%W alloys doped with thorium are currently used as post-impact containment material for radioactive fuel in thermoelectric generators that provide stable electrical power for a variety of outer planetary space exploration missions. Welding and weldability of a series of alloys was investigated using arc and laser welding processes. Some of these alloys are prone to severe hot-cracking during welding. Weldability of these alloys was characterized using Sigmajig weldability test. Hot-cracking is influenced to a great extent by the fusion zone microstructure and composition. Thorium content and welding atmosphere were found to be very critical. The weld cracking behavior in these alloys can be controlled by modifying the fusion zone microstructure. Fusion zone microstructure was found to be controlled by welding process, process parameters, and the weld pool shape.

The primary motivation for the present work is to provide theoretical values for the ratio of the partial ²³⁹Pu(n,2nx{gamma})²³⁸Pu to total ²³⁹ Pu(n,2n)²³⁸Pu cross section for several discrete gamma transitions. Results and conclusions of preliminary calculations from threshold to 20 MeV are presented. Calculations are based on theoretical models with parameters obtained from the literature or from our ad hoc systematics. Optical model cross sections and transmission coefficients were determined using the coupled-channels method. The calculations included a preequilibrium component followed by multiple particle and gamma-ray emissions. Fission competition was included at all stages of de-excitation. Suggestions for further verifications and possible improvements are provided.

The variational nodal method is formulated such that the angular and spatial approximations maybe examined separately. Spherical harmonic, simplified spherical harmonic, and discrete ordinate approximations are coupled to the primal hybrid finite element treatment of the spatial variables. Within this framework, two classes of spatial trial functions are presented: (1) orthogonal polynomials for the treatment of homogeneous nodes and (2) bilinear finite subelement trial functions for the treatment of fuel assembly sized nodes in which fuel-pin cell cross sections are represented explicitly. Polynomial and subelement trial functions are applied to benchmark water-reactor problems containing MOX fuel using spherical harmonic and simplified spherical harmonic approximations. The resulting accuracy and computing costs are compared.

Theoretical and experimental studies into monolithic millimeter-wave and picosecond electronic technologies have been undertaken as a collaborative project between the Lawrence Livermore National Laboratory (LLNL) and the University of California Department of Applied Science Coherent Millimeter-Wave Group under the auspices of the Laboratory Directed Research and Development Program at LLNL. The work involves the design and fabrication of monolithic frequency multiplier, beam control, and imaging arrays for millimeter-wave imaging and radar, as well as the development of high speed nonlinear transmission lines for ultra-wideband radar imaging, time domain materials characterization and magnetic fusion plasma applications. In addition, the Coherent Millimeter-Wave Group is involved in the fabrication of a state-of-the-art X-band ({approximately}8-11 GHz) RF photoinjector source aimed at producing psec high brightness electron bunches for advanced accelerator and coherent radiation generation studies.

Sandia is manufacturing CMOS ICs with 0.5 {micro}m LOCOS and shallow trench isolation (STI) technologies and is developing a 0.35 {micro}m SOI technology. A program based on burn-in and life tests is being used to qualify the 0.5 {micro}m technologies for delivery of high reliability ICs to customers for military and space applications. Representative ICs from baseline wafer lots are assembled using a high reliability process with multilayer hermetic, ceramic packages. These ICs are electrically tested before, during, and after burn-in and subsequent 1000 hour dynamic and static life tests. Two types of ICS are being used for this qualification, a 256K bit SRAM and a Microcontroller Core (MCC). Over 600 ICs have successfully completed these qualification tests, resulting in a failure rate estimate of less than 4 FITS for satellite applications. Recently, a group of SRAMS from a development wafer lot incorporating nonqualified processes of the 0.5 {micro}m LOCOS technology had an unusually high number of failures during the initial electrical test after packaging. The investigation of these failures is described.

This report documents the quality process plan for the restart of a hot cell in the B Plant, originally a bismuth phosphate processing facility, but later converted to a waste fractionation plant. B-Cell is currently being cleaned out and deactivated. TPA Milestone M-89-02 dictates that all mixed waste and equipment be removed from B-Cell by 5/31/1999. This report describes the major activities that remain for completion of the TPA milestone.

This SARP Upgrade Plan reflects a revised SARP upgrade schedule based on the most current program needs. A performance agreement has been assigned, beginning in FY 1997, to update, revise, and/or cancel 20 percent of the existing onsite SARPS, so that 100 percent are reviewed and within current standards by the completion of the Project Hanford Management Contract (five-year period).

In the early 1990s, the US Department of Energy (DOE) undertook a major new effort to involve community stakeholders in decisions that would affect them and their communities and interests. An important component of this effort was the establishment of local Site-Specific Advisory Boards (SSABs) at 12 DOE environmental remediation sites. These boards were a formal representation of a change in the way DOE conducts its missions, adding consideration of community concerns and values to the Department's decision-making processes. DOE's purpose in creating the SSAB Initiative was to obtain broadly based, independent, consensus advice and recommendations on issues that have the potential to affect communities surrounding DOE sites, so that it could formulate policies that could be implemented with community consent. Because the boards represented a significant commitment by DOE to change its relationships with community stakeholders, the Department has conducted several assessments of the boards. In 1996 and 1997 a survey was administered to board members and others involved in the work of the boards (DOE/EM 0311, 1996; DOE/EM, 1997). As part of the first survey, DOE and the boards established a set of performance criteria. The surveys provided data that revealed wide variations in board performance and significant …

The Council on Environmental Quality (CEQ) regulations for implementing the NEPA, 40 CFR 1502.9 (c), directs federal agencies to prepare a supplement to an environmental impact statement when an agency makes substantial changes in the Proposed Action that are relevant to environmental concerns, or there are significant new circumstances or information relevant to environmental concerns and bearing on the Proposed Action or impacts. When it is unclear whether a supplemental environmental impact statement is required, DOE regulations (10 CFR 1021.314) direct the preparation of a supplement analysis to assist in making that determination. This supplement analysis evaluates the impacts of employing dual-purpose canisters (DPCs) to prepare DOE SNF located at the INEEL for interim onsite storage and transport outside the State of Idaho. Impacts associated with DPC manufacturing, loading and storage of DOE-ID SNF into DPCs, transport of loaded DPCs outside Idaho, and the cumulative impacts are compared with the impacts previously analyzed in the SNF and INEL EIS and the Navy Container System EIS. This SA provides information to determine whether: (1) an existing EIS should be supplemented; (2) a new EIS should be prepared; or (3) no further NEPA documentation is required.

This report documents the test results of OTP-320-001, Tank 241-AY-102 Annulus Ventilation System Testing. Included in the appendices are: (1) Supporting documentation prepared to demonstrate the structural integrity of the tank at high annulus vacuum (<20 INWG), and (2) a report that identifies potential cross connections between the primary and annulus ventilation systems. These cross connections were verified to be eliminated prior to the start of testing.

The steadily increasing plutonium production rates in the 234-5 Building has resulted in a large increase in the number of PR cans that are now being handled in the building. This has resulted in the available receiving and storage places for PR cans being taxed beyond their full capacity thereby necessitating the storage of PR cans within the building corridors. Accordingly, the ten-year business plan for the 234-5 Building, as documented in HW-65000, included a program for providing new receiving and storage facilities to alleviate this problem. The purpose of this document is to present a complete process engineering design on the combined receiving, storing, and blending facility. This document will provide the basis for the preparation of all subsequent Title 1 and Title 2 designs of this combined facility which has been given the title of Metal Control Facility.

This document describes the hardware and software required for the Federal Emergency Management Information System version 1.4.6 (FEMIS{copyright} v1.4.6).

This report evaluates the structural adequacy and the integrity of the existing core sampling trucks to withstand impact should the trucks drop off the ramp, either onto the soft ground or onto a non-yielding surface due to operational error, wind, or earthquake. The report also addresses if the allowable tank dome load will be exceeded by the addition of the impact load.

Los Alamos National Laboratory (LANL) and its contractors have developed a conceptual design for a directional microborehole drilling system for hard-rock boring. Analytical calculations, simulations, and the results of laboratory testing of critical prototype drilling components have influenced the design. Two reduced-size drilling systems to produce small diameter, 500-ft-long, directionally drilled river crossing trajectories are proposed to prove feasibility of the concept: (1) a 2-1/4-in. diameter, early demonstration unit to drill directional ultraslimholes; and (2) a 1-1/8-in. diameter, ultimate design to drill directional microboreholes. Both concepts use versatile, coiled-tubing-deployed, hydraulically-powered drilling assemblies, and a surface platform that includes a tubing injector unit to develop high load insertion (snubbing) of the tubing into the sealed borehole. Surface injection will be used to develop the required bit thrust, and both concepts provide for the use of a commercial, real-time, location and steering system that is readily and routinely adapted for deployment on a coiled-tubing drilling platform. The conceptual drilling platform and its subassemblies are shown.

This Technical Progress Report summarizes activities conducted over the period 8/16/96-2/15/97 as part of this project. This investigation responds to the possibility that restrictions on greenhouse gas emissions may be imposed in the future to comply with the Framework Convention on Climate Change. The primary objective of the investigation is to obtain experimental data that can be applied to assess the technical feasibility and environmental impacts of oceanic containment strategies to limit release of carbon dioxide (CO{sub 2}) from coal and other fossil fuel combustion systems into the atmosphere. Critical technical uncertainties of ocean disposal of CO{sub 2} will be addressed by performing experiments that: (1) characterize size spectra and velocities of a dispersed CO{sub 2} phase in the near-field of a discharge jet; and (2) estimate rates of mass transfer from dissolving droplets of liquid CO{sub 2} encased in a thin hydrate shell. Experiments will be conducted in a laboratory facility that can reproduce conditions in the ocean to depths of 600 m (1,969 ft). Between 8/16/96 and 2/15/97, activities focused on modifications to the experimental apparatus and the testing of diagnostics. Following completion of these tasks, experiments will be initiated and will continue through the end of the …
