3-D TECATE/BREW: Thermal, stress, and birefringent ray-tracing codes for solid-state laser design

Description: This report describes the physics, code formulations, and numerics that are used in the TECATE (totally Eulerian code for anisotropic thermo-elasticity) and BREW (birefringent ray-tracing of electromagnetic waves) codes for laser design. These codes resolve thermal, stress, and birefringent optical effects in 3-D stationary solid-state systems. This suite of three constituent codes is a package referred to as LASRPAK.

Angular biasing in implicit Monte-Carlo

Description: Calculations of indirect drive Inertial Confinement Fusion target experiments require an integrated approach in which laser irradiation and radiation transport in the hohlraum are solved simultaneously with the symmetry, implosion and burn of the fuel capsule. The Implicit Monte Carlo method has proved to be a valuable tool for the two dimensional radiation transport within the hohlraum, but the impact of statistical noise on the symmetric implosion of the small fuel capsule is difficult to ove… more

B-physics at RHIC: An opportunity

Description: B physics provides a unique window for investigation and confirmation of our picture of CP violation, as well as an opportunity to explore physics beyond the Standard Model. Because of this richness of physics, programs for the study of the B sector are in progress or under development at most of the major facilities for high energy physics in the world. In this note we suggest that a B program at the RHIC facility at BNL could provide timely and complementary information to our understanding o… more

Channel probe measurements for the American sector clutter experiment, January, 1994

Description: The ionospheric phenomenon called Equatorial Spread F encompasses a variety of effects associated with plasma irregularities occurring in the post-sunset and nighttime ionosphere near the magnetic equator. These irregularities can seriously degrade the performance of systems which involve either of necessity or inadvertently radio propagation through the equatorial ionosphere. One such system is Over-the-Horizon (OTH) radars which operate in the high-frequency (hf) band and use ionospheric refl… more

Characterization of rock for constraining reservoir scale tomography at the Geysers geothermal field

Description: A suite of laboratory measurements are being conducted on Geysers graywacke recovered from a drilled depth of 2599 meters in NEGU-17. The tests are being conducted to characterize the effect of pressure and fluid saturation on the seismic properties of the graywacke matrix. The measurements indicate that the graywacke is an unusual rock in many respects. Both compressional and shear velocities exhibit relatively little change with pressure. Water saturation causes a slight increase in the compr… more

Characterization of subsurface fracture patterns in the Coso geothermal reservoir by analyzing shear-wave splitting of microearthquake seismorgrams

Description: A large number of microearthquake seismograms have been recorded by a downhole, three-component seismic network deployed around the Coso, California geothermal reservoir. Shear-wave splitting induced by the alignment of cracks in the reservoir has been widely observed in the recordings. Over 100 events with body wave magnitude greater than 1.0 from microearthquakes recorded since March of 1992. have been processed. The results show that most events with paths within the critical angle that defi… more

Computer program to analyze multipass pressure-temperature-spinner surveys

Description: A computer program has been developed to analyze multipass pressure-temperature-spinner surveys and summarize the data in graphical form on two plots: (1) an overlay of spinner passes along with a fluid velocity profile calculated from the spinner and (2) an overlay of pressure, pressure gradient, and temperature profiles from each pass. The program has been written using SmartWare II Software. Fluid velocity is calculated for each data point using a cross-plot of tool speed and spinner counts … more

CSAR 81-001 addendum 2: Use of a plexiglass contamination barrier in HC-227-T

Description: Plutonium Finish Plant (PFP) Engineering requested a criticality safety evaluation (Appendix 1) to support a revision of Criticality Prevention Specification CPS-Z-165-80601 allowing a plexiglass enclosure (PGE) to be placed inside the HC-227T hood as a contamination barrier. The HC-227T hood is the receiving/transfer enclosure for Pu nitrate solution contained in Product Removal containers (PR Cans), L10 Containers (L10, Fl-10, 10 L) or L-3 Containers. Within the HC-227T, a 1.349 square meter … more

Decontamination and decommissioning of Plant 7 at the Fernald Facility

Description: The Fernald Environmental Management Project (FEMP), formerly the Feed Materials Production Center (FMPC), is a Department of Energy (DOE) site which produced high-quality uranium for military defense beginning in 1951. Production at the FEMP was halted in July 1989. Later that year, the facility was placed on the National Priorities List (NPL). The DOE is currently conducting a Remedial Investigation/Feasibility Study (RI/FS) and other response actions under the Amended Consent Agreement betwe… more

Defense Burdensharing: Is Japan's Host Nation Support a Model for Other Allies?

Description: This report reviews data that the Administration has provided to Congress on the costs of U.S. forces based abroad and on the value of host nation support contributions. It analyzes the data in order to assess potential defense budget savings from measures now under congressional consideration. The report concludes that, because of shortcomings in the data, estimates of savings in the U.S. defense budget from increased host nation contributions are often overstated. Some commonly accepted asser… more

Defense Burdensharing: Is Japan's Host Nation Support a Model for Other Allies?

Description: Under an agreement announced in January 1991, the Government of Japan committed itself to increase substantially the amount of support that it provides for U.S. military forces based there. Among other things, Japan agreed by 1995 to absorb 100 percent of the cost of Japanese nationals employed at U.S. military facilities and to pay for all utilities supplied to U.S. bases, to increase the amount of military and family housing construction that it is providing to support U.S. forces, to continu… more

Development of Ceramic-Coated Weld Backing Bars

Description: In shipbuilding and many other industries, copper weld backing bars are used to draw the heat out of the weld. The problem that some users of these bars encounter is that these bars, on occasion, actually melt in spots and become welded to the weld plates. After this happens a number of times, the backing bar becomes so degraded that it must be either discarded or machined, both of which are very costly and time-consuming actions. To avoid this fusion between the backing bar and the weld plate,… more

Direct conversion of spent fuel to High-Level-Waste (HLW) glass

Description: The Glass Material Oxidation and Dissolution System (GMODS) is a recently invented process for the direct, single-step conversion of spent nuclear fuel (SNF) to high-level waste (HLW) glass. GMODS converts metals, ceramics, organics, and amorphous solids to glass in a single step. Conventional vitrification technology can not accept feeds containing metals or carbon. The GMODS has the potential to solve several issues associated with the disposal of various US Department of Energy (DOE) miscell… more

Double-diffusive convection in liquid-dominated geothermal systems with high-salinity brines

Description: Variations in temperature and salinity in hypersaline liquid-dominated geothermal systems like the Salton Sea Geothermal System (SSGS) tend to be correlated such that liquid density is relatively constant in the system. The tendency toward small density variations may be due to connectivity with a surrounding regional aquifer at multiple depths in the stratigraphic column. We present numerical simulation results for natural convection in geothermal systems like the SSGS in hydraulic connection … more
