Cascade: a review of heat transport and plant design issues

Description: A conceptual heat transfer loop for Cascade, a centrifugal-action solid-breeder reaction chamber, has been investigated and results are presented. The Cascade concept, a double-cone-shaped reaction chamber, rotates along its horizontal axis. Solid Li/sub 2/O or other lithium-ceramic granules are injected tangentially through each end of the chamber. The granules cascade axially from the smaller radii at the ends to the larger radius at the center, where they are ejected into a stationary granul… more

Characterization of the solid, airborne materials created by the interaction of UF/sub 6/ with atmospheric moisture in a contained volume

Description: Several experiments have been performed in which UF/sub 6/ was released into air under static conditions in a 6 m/sup 3/ release chamber in order to characterize the solid products of hydrolysis as the amount of UF/sub 6/ released was increased. An aerosol concentration of approx. 25 gm/m/sup 3/ (150 gm) was the largest achieved. Electron microscopy was used to determine the morphology of the aerosol particles and to obtain geometric size measurements from micrographs and a cascaded impactor wa… more

Municipal solid waste energy conversion study on Guam and American Samoa

Description: In the Pacific Islands of Guam and Tutuila in American Samoa, conversion of municipal solid waste to useable energy forms - principally electricity but possibly steam - may hold promise for reducing economic dependence on imported petroleum. A secondary benefit may be derived from reduction of solid waste landfill requirements. At the preliminary planning stage, waste-to-energy facilities producing electricity appear technically and environmentally feasible. Economically, the projects appear ma… more

Pressure phase lines and enthalpies for the. cap alpha. -. beta. and. beta. -liquid transitions in beryllium

Description: The effect of hydrostatic pressure on the ..cap alpha..-..beta.. and ..beta..-liquid transition temperatures in Be was measured in a gas pressure system. Differential thermal analysis was used in the pressure range from 0.1 MPa to 0.7 GPa. For the ..cap alpha..-..beta.. transition, dT/dP = 43 +- 7 K/GPa; for the ..beta..-liquid transition, dT/dP = 35 +- 7 K/GPa. Although it is possible that large systematic errors may arise from experimental procedures, our results are seriously at odds with th… more

Message development for surface markers at the Hanford Radwaste Disposal sites

Description: At the Hanford Reservation in Washington, there are sites which received liquid and solid transuranic wastes from the late 1940`s until 1970. Rockwell Hanford Operations (Rockwell) is investigating the feasibility of several options for the permanent disposal of these wastes. One option is to stabilize the wastes in their present locations and to add barriers to minimize water infiltration and root penetration into the wastes. This report forms part of the project to develop a marking system fo… more

Rock Matrix and Fracture Analysis of Flow in Western Tight Gas Sands. Quarterly Technical Progress Report, September--December 1984

Description: The presence of natural fractures is often cited as a key factor in gas production for both fractured and unfractured wells. Numerous vertical fractures have been found in cores recovered in the Multi-Well Project. The cores show that by far the majority of fractures become filled with calcite cement. However, calcite-filled fractures are not necessarily a seal to gas flow. As part of this project, flow measurements are being made along and across selected fractured samples as a function of ove… more

Federal geothermal royalty income derived from the benefits of government-sponsored R and D

Description: The ability of Federally-sponsored geothermal R and D to, in effect, pay for itself through increased royalty payments resulting from enhanced resource development on Federal lands is investigated. The report concludes that achievement of current Federal R and D objectives is likely to result in significant royalty returns to both state and Federal governments. These returns are measured in terms of the increase in royalty payments attributable to the achievement of Federal R and D objectives, … more

Behavior of nuclear waste elements during hydrothermal alteration of glassy rhyolite in an active geothermal system: Yellowstone National Park, Wyoming

Description: The behavior of a group of nuclear waste elements (U, Th, Sr, Zr, Sb, Cs, Ba, and Sm) during hydrothermal alteration of glassy rhyolite is investigated through detailed geochemical analyses of whole rocks, glass and mineral separates, and thermal waters. Significant mobility of U, Sr, Sb, Cs, and Ba is found, and the role of sorption processes in their observed behavior is identified. Th, Zr, and Sm are relatively immobile, except on a microscopic scale. 9 references, 2 figures, 2 tables.

Miscellaneous investigations series: Bedrock geologic map of the Lone Mountain pluton area, Esmeralda County, Nevada

Description: The joint attitudes were measured in the field and plotted on aerial photos at a scale of 1:24,000. The pluton is intensely jointed, primarily as a result of cooling and movement of the magma within a northwest-trending stress field. Foliation, in general, is poorly developed, and quality varies from area to area, but it is best developed close to the contacts with the metasedimentary rocks. A prominent northwest foliation direction was observed that parallels the northwest elongation of the ex… more
