Review of ARHCO Waste Tank Leak and Level Monitoring Systems and Material Balance Techniques

Description: A review of selected portions of the ARHCO waste tank farm monitoring methods and systems was made. Only preliminary evaluations were made as the study was carried out over a period of only ten days. The study was requested by the Operation Support Engineering Department of ARHCO and the objectives as developed were divided into four tasks. Briefly, these were: evaluation of the waste tank dry well monitoring and data processing systems; evaluation of the accuracy (and precision) of material ba… more

Development of high-specific-energy batteries for electric vehicles. Progress report, February 1973--July 1973

Description: A high-specific-energy lithium/sulfur battery having the performance characteristics required for powering pollutionfree automobiles is described. The cells currently under development have negative electrodes of molten lithium and positive electrodes of sulfur (plus an additive to reduce the sulfur vapor pressure) separated by a molten lithium halide-containing electrolyte. The operating temperature of the cells is about 400 deg C. The performance goals for a single cell include a capacity den… more

Voltage holding considerations for direct-collection units

Description: Results have been obtained from initial experiments designed to study high-voltage breakdown under conditions of importance to the design of direct- collection units. A coaxial configuration was used to mock-up critical fields near grid wires. With appropriate heat conditioning, fields as high as 9.6 x 10/ sup 5/ V/cm were maintained at the surface of a 7-mil-diam tungsten wire. This represents an enhanced field of ~10/sup 8/V/cm at whisker'' sites. Breakdown criteria are proposed for three reg… more

''Ideal'' directly executed languages: an analytical argument for emulation

Description: Several methods of evaluating user programs are analyzed with respect to space and time requirements. The concept of an ideal'' directly executed language is introduced, and it is argued that the ideal'' directly executed language for a contemporary computing system will not be either its source language or the language accepted by its base machine.

Ingot beryllium-microstructural and mechanical property changes during can- rolling

Description: Microstructural and mechanical property observations of ingotsource beryllium at selected points in the can-rolling process are reported. Recrystallization occur s concurrently with rolling at temperatures above 1800 deg F, and only partial recrystallization is observed during reheats at 1400 deg F. Most grain refinement induced by the rolling schedule occurs in the first 15 rolling passes. These represent 88 percent reduction from the ingot. A relatively small contribution comes from the final… more

Data sheets for PPO radioisotopic fuel

Description: PPO is the acronym for Pure Plutoniunn Oxide. The thermal energy of this fuel results from the radioactive decay of /sup 238/ Pu this energy is converted into usable electric power for space probe or other applications. The basic fuel module associated with the current MHW heat source is a PPO sphere 1.465 plus or minus 0.015 in. in dia and containing 100 plus or minus 2 thermal watts. The spheres are individually encapsulated and then assembled into geometric arrays to form the working heat so… more

Non-relativistic current algebra in the N/V limit

Description: The case of a noninteracting infinite Bose gas at zero temperature is studied in the formalism of local current algebras, using the representation theory of nuclear Lie groups. The class of representations describing such a system is obtained by taking an N/V limit'' of the finite case. These representations can also be determined uniquely from the solutions of a functional differential equation, which follows in turn from a condition on the ground state vector. Finally a system of functional d… more

Batch system with rapid overlay capabilities

Description: A batch supervisor for a minicomputer has been written which provides rapid sequencinig between jobs. The supervisor can handle a small number of system programs, and also allows each system program to have a large number of overlays. Overlays are read into core rapidly, and the sequencing of overlays and job steps is very flexible. Finally, the supervisor is small, leaving most of the minicomputer's core storage to the system programs. (auth)
