Advanced Reservoir Characterization in the Antelope Shale to Establish the Viability of CO{sub 2} Enhanced Oil Recovery in California's Monterey Formation Siliceous Shales

Description: The Buena Vista Hills field is located about 25 miles southwest of Bakersfield, in Kern County, California, about two miles north of the city of Taft, and five miles south of the Elk Hills field. The Antelope Shale zone was discovered at the Buena Vista Hills field in 1952, and has since been under primary production. Little research was done to improve the completion techniques during the development phase in the 1950s, so most of the wells are completed with about 1000 ft of slotted liner. Th… more

Approaches to instrument design at pulsed neutron sources

Description: A number of tools are used in the design of scattering instruments for pulsed neutron sources. Initial design is based largely on simple analytical calculations. More complicated analytical calculations and Monte Carlo simulations come into play as the design is optimized to maximize the data rate and to improve the data quality. Examples are used to illustrate the relative roles of these different computational tools. Areas are also identified where appropriate computational tools are currentl… more

Audit of management of the laboratory directed research and development program at the Lawrence Livermore National Laboratory

Description: The Department`s national laboratories, since their establishment, have been permitted to conduct a limited amount of discretionary research activities. The Department`s Defense Program laboratories, such as the Lawrence Livermore National Laboratory, generate funding for Laboratory Directed Research and Development (LDRD) programs by charging their total laboratory operating and capital equipment budgets a flat surcharge of up to 6 percent. The ceiling was mandated by the Congress in authoriza… more

Back-side emissions from filtered gold targets

Description: An investigation of the rapid rise time of incoherent x-ray emission from targets heated by an ultra-short pulse (USP) high-intensity optical laser was conducted for use as the x-ray source for inner- shell photo-ionized (ISPI) x ray lasing. Previous studies considered front-side x-ray emission; however, ISPI x-ray lasing requires a filtered x-ray source. Modeling using the hydrodynamics/atomic kinetics code LASNEX of a 40 fs USP driving laser with an intensity of 10 exp(17W/CM2) incident on a … more

Calculation of thermal diffuse scattering

Description: The authors developed a computer program to calculate the thermal diffuse scattering (TDS) intensity distribution for single crystal specimens in a diffractometer with no energy analysis. They assumed that the phonon frequencies are approximated by those of elastic waves and that the elastic constants, density and lattice parameters of the system under study are known. The results of the calculations were compared to experimental data obtained for single crystals of Si, diamond and NiAl at the … more

Characterization of U-6Nb ingots produced via the electron beam cold hearth refining process

Description: A study was undertaken at Lawrence Livermore National Laboratory to characterize uranium, 6% niobium ingots produced via electron beam melting, hearth refining and continuous casting and to compare this material with conventional VIM/skull melt/VAR material. Samples of both the ingot and feed material were analyzed for niobium and trace metallic elements, carbon, oxygen and nitrogen. This material was also inspected metallographically and via microprobe analysis.

Commercial Fishing: Economic Aid and Capacity Reduction

Description: Both experience and economic models show that, in the absence of enforceable access or catch restrictions, competition among commercial fishermen results in an expansion of fishing capacity, and resultant fishing effort, beyond the sustainable limits of the fish population being pursued. The spiral of increasing effort and diminishing returns (i.e., rent dissipation) has helped to fuel increases in fish prices that reduce benefits to consumers and processors; has shifted many fish populations t… more

Consequences of a postulated tank bump related to Project W-320

Description: An analysis was performed of radiological and toxicological consequences of a conservative tank bump scenario which could occur if preventative measures fail and the local sludge temperature exceed the saturation temperature for a long enough period of time to produce a release of this type. Because of the nature of the release, there are no effective mitigative actions which can be taken other than prevention of the tank bump. The unmitigated scenario analyzed here exceeded both onsite and off… more

Cost avoidance techniques through the Fernald controlled area trash segregation program and the RIMIA solid waste reduction program

Description: The Fernald Environmental Management Project is a Department of Energy owned facility that produced high quality uranium metals for military defense. The Fernald mission has changed from one of production to remediation. Remediation is intended to clean up legacy (primary) waste from past practices. Little opportunity is available to reduce the amount of primary waste. However, there is an opportunity to reduce secondary waste generation, primarily through segregation. Two programs which accomp… more

CSER 97-001 Criticality safety limits for PFP 26-inch vacuum lineremoval

Description: As part of the plutonium stabilization operations in the 234-5Z Building, several runs of 26-inch (26 inches of Hg) process vacuum header, along with associated smaller piping is to be cut into sections and disposed of. This criticality safety evaluation report (CSER) requested by Nirider (1996) addresses the removal of several hundred feet of abandoned 3 and 4 inch nominal diameter vacuum header and associated smaller diameter piping runs located in the duct level of the 234-5Z Building in roo… more

Demonstrations of diode-pumped and grating-tuned ZnSe:Cr{sup 2+} lasers. Revision 1

Description: A diode-side-pumped ZnSe:Cr{sup 2+} laser was operated with a 75 - Watt peak power 1.65 {micro}m InGaAsP/InP pump array. The laser was configured with a ``single-bounce`` architecture to maximize its round-trip gain. Peak output powers of {approx}0.3 Watt were obtained with a 10% - transmitting output coupler and a lightly-doped crystal. The estimated ``mode fill`` of {approx}0.06 will increase with Cr{sup 2+} concentration, raising the output power and extraction efficiency. With a grating tun… more

DKPRO: A radionuclide decay and reprocessing code

Description: The DKPRO code solves the general problem of modeling complex nuclear wastes streams using ORIGEN2 radionuclide production files. There is a continuing need for estimates of Hanford radionuclides. Physical measurements are one basis; calculational estimates, the approach represented here, are another. Given a known nuclear fuel history, it is relatively straightforward to calculate radionuclide inventories with codes such as the widely-used Oak Ridge National Laboratory code ORIGEN2.

DOE Laboratory Restructuring Legislation in the 104th Congress

Description: Interest in restructuring (including eliminating) the Department of Energy (DOE) and its laboratories has increased since the end of the Cold War, and especially since the beginning of the 104th Congress. A number of non-legislative proposals and activities to this end are reviewed, including DOE's own proposals for "alignment and downsizing" of the Department and its laboratories.

Engineered Barrier System performance requirements systems study report. Revision 02

Description: This study evaluates the current design concept for the Engineered Barrier System (EBS), in concert with the current understanding of the geologic setting to assess whether enhancements to the required performance of the EBS are necessary. The performance assessment calculations are performed by coupling the EBS with the geologic setting based on the models (some of which were updated for this study) and assumptions used for the 1995 Total System Performance Assessment (TSPA). The need for enha… more

Environmental Protection Agency: FY1998 Budget

Description: EPA appropriations are included in the annual VA-HUD-Independent Agencies Appropriation Bill. Two major issues were whether Superfund cleanups should be accelerated in the absence of statutory reforms and whether the requested state assistance funds are adequate. Because the House and Senate were in agreement on not granting the requested 50% increase in Superfund and in passing increased state funds, the chief conference issue was expected to focus on the roughly $225 million difference betwee… more
