Final report on a calculational parameter study of soils typical of some ESSEX I cratering sites

Description: The one-dimensional computer calculations described in this report were performed to simulate stress-wave propagation and kinetic energy transfer associated with subsurface cratering detonations in soils. A hypothetical 20-ton-yield nuclear explosive was assumed as the energy source, surrounded by a single soil material. Various soil descriptions were selected in order to systematically study the range of soil response to the nuclear detonation. The soils were representative of the layered mixt… more

Engineering report: vacuum test facility requirements ERDA BIPS GDS

Description: Results of a study undertaken to define the requirements for a reference vacuum test facility, as well as some operating procedures for the Phase I Brayton Isotope Power System (BIPS) Ground Demonstration System (GDS) are reported. The vacuum system is required to simulate the space environment in which the BIPS flight system will function. The BIPS GDS will require a high vacuum environment during performance and endurance testing to enable the multi-foil insulation to be effective and to prot… more

Brayton Isotope Power System. Phase I. (Ground demonstration system) Configuration Control Document (CCD)

Description: The configuration control document (CCD) defines the BIPS-GDS configuration. The GDS configuration is similar to a conceptual flight system design, referred to as the BIPS-FS, which is discussed in App. I. The BIPS is being developed by ERDA as a 500 to 2000 W(e), 7-y life, space power system utilizing a closed Brayton cycle gas turbine engine to convert thermal energy (from an isotope heat source) to electrical energy at a net efficiency exceeding 25 percent. The CCD relates to Phase I of an E… more

Energy conservation and management plan for plant facilities at the Livermore site

Description: An energy conservation and management plan for the Livermore site of the Lawrence Livermore Laboratory is presented. The plan defines the energy-conservation goals for the next 10 years and proposes the ways and means of attaining them. The main features contained in this plan are as follows: development of the criteria and underlying assumptions required for long range planning, including energy growth rates and the case for using the concept of the technical-fix energy growth rate, LLL energy… more

X-ray diffraction time-study of uranium tritide materials. [To determine effects of /sup 3/He buildup on lattice parameters]

Description: X-ray powder diffraction analyses of bulk uranium tritides, as a function of time, have been accomplished. The analyses were run during an overall time span of two years. This study was undertaken to determine whether any observable effects of the /sup 3/He buildup could be detected by means of lattice parameter measurements. Four tritiated uranium samples were investigated. The data obtained from three of these samples show expansion of their lattices to be as anticipated. The fourth sample yi… more

Disposal of transuranic solid waste using Atomics International's molten salt combustion process. II

Description: The Atomics International Molten Salt Combustion Process reduces the weight and volume of combustible transuranic waste by utilizing a molten salt medium to combust organic materials, to trap particulates and fissile material, and to react chemically with any acidic gases produced during combustion. The ''ash'' is retained by the molten salt. To control the amount of noncombustible substances in the melt, a portion of the molten salt is periodically drained from the combustor. There are two opt… more

Correlation of Substructure With Mechanical Properties of Plastically Deformed Reactor Structural Materials. Progress Report, January 1, 1974--December 31, 1975

Description: Ratio of the subgrain boundary dislocations to those contributing to creep deformation was found to be independent of applied stress and creep strain after the steady-state creep stage is reached. The observed cell or subgrain sizes are correlated with flow stress in Type 304 ss, and the deformation rate-stress relation obeys the equation epsilon =..beta.. lambda/sup 3/ (sigma/sub T//E)/sub n/ exp (-Q/sub c//RT), where lambda = subgrain size, sigma/sub T/ = effective true stress, E = Young modu… more

Large area silicon sheet by EFG. Second quarterly progress report, January 1, 1976--March 31, 1976

Description: The thin/fast growth system (JPL No. 2) is modified and operational. An orientation study was run on this system prior to the changeover and thermal geometry experiments have been run since. (110) (211) seed orientation appears to be the optimum. Solar cells have been fabricated from the ribbon material and tested. The wide ribbon system (JPL No. 1) is being designed. Some parts are ordered. The theoretical analysis of heat flow in EFG silicon growth is expanded.
