Testing and evaluation of doubly impacted simulant-fueled Milliwatt Generator heat sources

Description: As part of the Milliwatt Generator (MWG) Program, 12 simulant-fueled heat sources were fabricated double impact tested, and evaluated at Mound. Ten assemblies were tested at approx. 80 m/sec, and two were tested at approx. 105 m/sec. None of the strength members were breached; therefore, no fuel would have been released as a result of double impacts at the velocities and orientations tested at 450/sup 0/C. There was little difference in results for duplicate tests conducted approx. 80 and appro… more

Conceptual design study FY 1981: synfuels from fusion - using the tandem mirror reactor and a thermochemical cycle to produce hydrogen

Description: This report represents the second year's effort of a scoping and conceptual design study being conducted for the express purpose of evaluating the engineering potential of producing hydrogen by thermochemical cycles using a tandem mirror fusion driver. The hydrogen thus produced may then be used as a feedstock to produce fuels such as methane, methanol, or gasoline. The main objective of this second year's study has been to obtain some approximate cost figures for hydrogen production through a … more

Nuclear waste-form risk assessment for US defense waste at Savannah River Plant. Annual report FY, 1982

Description: A network model was developed to simulate the hydrological flow and the transport of radionuclides from a deep geological repository to the biosphere subsequent to closure. By means of very efficient computational methods for solving the fundamental differential equations, a code was developed to treat in great detail the effects of waste form characteristics and of repository designs on the repository risks. It is possible to examine near field effects heretofore not attempted. Without sacrifi… more

Brief reconnaissance study for the addition of hydropower for Mayodan Dam, Mayodan, North Carolina

Description: The feasibility of retrofitting the Mayodan Dam near Mayodan, North Carolina for power generation was examined. This dam, which has a developable head of 20 ft., was built in 1920 for impounding a small run-of-the-river water reservoir. The study of environmental, institutional, safety and economic factors showed that hydroelectric power development at this site appears to be economically feasible. (LCL)

Technical evaluation of the adequacy of station electric distribution systems voltages for the Calvert Cliffs Nuclear Power Plant, Units 1 and 2. Docket Nos. 50-317, 50-318

Description: This report documents the technical evaluation of the adequacy of the station electric distribution system voltages for the Calvert Cliffs Nuclear Power Plant, Units 1 and 2. The evaluation is to determine if the onsite distribution system in conjunction with the offsite power sources has sufficient capacity to automatically start and operate all Class 1E loads within the equipment voltage ratings under certain conditions established by the Nuclear Regulatory Commission. The analyses submitted … more

Immobilization of sodium and phosphorus-bearing PW-7a waste in SYNROC. Progress report. [SYNROC C]

Description: The phosphorus, sodium and gadolinium-rich PW-7a waste can be successfully incorporated in SYNROC-C. However, a new accessory phase, a Ca,Na,Ba phosphate isostructural with Ca/sub 5/Na/sub 2/(PO/sub 4/)/sub 4/ apppears in the SYNROC mineralogy. There is no evidence for the partition of key radionuclides (e.g. Sr, REE and hence actinides) into this phosphate. Its poor resistance to groundwater dissolution, whilst hardly desirable, may therefore not have a serious effect on the leaching performan… more

Empirical analysis of seismic records for eleven nuclear tests at the Nevada Test Site

Description: Regional seismic records for eleven underground nuclear explosions were processed and analyzed (empirically) in a search for source and path related patterns in the signals. These nuclear tests were conducted between August, 1979 and April, 1980; all were located in Yucca Flat at the Nevada Test Site (NTS). The seismic signals generated by these explosions were recorded on the LLNL four-station network, located at distances of 200 to 400 km from the NTS. Amplitudes were measured for consistentl… more

Leasing of Energy and Mineral Resources on Federal Lands

Description: This report discusses the leasing of energy and mineral resources on federal lands. Leasing of energy minerals has been an issue of varying intensity for most of the past century, as oil, gas, and coal became indispensable commodities in both U.S. and world commerce.
