Six phase rectifier digital computer simulation (open access)

Six phase rectifier digital computer simulation

A digital computer program has been developed for the simulation of a six-pulse converter with a resistance-inductance load. The program calculates the time histories of the voltages and currents on both the ac and dc sides of the rectifier bridges. The grid delay angle is calculated in terms of the load current, supply voltage, and commutating reactance. The program is written in FORTRAN and is executable on the CDC7600 Plotted output of ten variables can be requested. This program is a preliminary effort toward the development of analytical and programming techniques that can be used in the simulation of the twelve-pulse controlled rectifiers in the TFTR toroidal field coil energy conversion system.

Cover-gas seals. FFTF-LMFBR seal-test program. Progress report, January-March 1975 (open access)

Cover-gas seals. FFTF-LMFBR seal-test program. Progress report, January-March 1975

The objectives of the general seal test program are to: (1) conduct static and dynamic tests to demonstrate or determine the mechanical performance of full-size (cross section) FFTF fuel transfer machine and reactor vessel head seals intended for use in a sodium vapor - inert gas environment, (2) demonstrate that these FFTF seals or new seal configurations provide acceptable fission product and cover gas retention capabilities at Clinch River Breeder Reactor Plant (CRBRP) operating environmental conditions other than radiation, (3) develop improved seals and seal technology for the CRBRP to support the national objective to reduce all atmospheric contaminations to low levels, and (4) publish a Design Guide for reactor seals along with Ordering Data.

Study on reduction of accessory horsepower requirements. Fourth quarterly progress report (open access)

Study on reduction of accessory horsepower requirements. Fourth quarterly progress report

The program objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial three program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. During this quarter the major program accomplishments were: selection of candidate belt-drive concepts; completion of Phase III baseline vehicle drive systems physical and operational envelopes; completion of analysis for a mechanically controlled direct-operated belt drive with input programming; and completion of design layout and analysis for a hydromechanically controlled, servo-operated belt drive with output-speed sensing.

Memorandum on the dipole--dipole resistivity results over the East Mesa geothermal anomaly, Imperial Valley, California (open access)

Memorandum on the dipole--dipole resistivity results over the East Mesa geothermal anomaly, Imperial Valley, California

Some of the results of a resistivity survey completed over the East Mesa geothermal anomaly in Imperial County, California are presented. The area of the heat flow high correlates quite closely with a gravity high and with a seismic ground noise high. A reconnaissance resistivity survey using the Schlumberger electrode configuration was also completed in the Imperial Valley. These data show that a weak resistivity low exists at the East Mesa, at the contact between very low resistivity sediments to the west and slightly higher resistivity rocks to the east. Dipole-dipole resistivity measurements were made through the center of the heat-flow high using x = 2,000', N = 1,2,3,4,5 along lines about five miles long. The results indicate a distinct resistivity low, at depth, that correlates with the East Mesa geothermal high. The details of the resistivity low can be seen much more clearly in the dipole-dipole data than from the reconnaissance survey. (JGB)

Numerical study of boundary layer injection as a scale control method (open access)

Numerical study of boundary layer injection as a scale control method

A boundary layer injection method of controlling scale-buildup in geothermal two-phase flow nozzles is studied. The object of this study is to set an upper limit on the ratio of the injected mass flow rate to the free stream mass flow rate that is necessary to isolate the scale carrying free stream flow from the nozzle wall. In order to develop a numerical model of the boundary layer flow, assumptions are made which reduce the results to order of magnitude approximations. Two configurations of nozzles with various injection flow rates are tried. It is found by numerical experiment that a nozzle with injection through a 1 mm thick ring near the inlet, is more efficient at isolating the free stream than a porous nozzle. A mass flow rate ratio of 0.173% was necessary to achieve this effect. It may be concluded that an upper limit on the mass flow rate ratio is about 2.0% with injection through a ring near the inlet, and that boundary layer injection is a reasonable method of controlling scale-buildup. A glossary of variables, program documentation and listings are presented for programs GMD15SR8, TRACK11, and TRACK12.

Magma fuel cell. [For energy extraction from magma or for electrochemical protection of heat exchangers in magma] (open access)

Magma fuel cell. [For energy extraction from magma or for electrochemical protection of heat exchangers in magma]

A high temperature, solid-electrolyte fuel cell is described which uses molten rock having oxidizable constituents as a fuel. The principles of this magma fuel cell have been successfully demonstrated and power densities of 88 W/m/sup 2/ have been achieved. If power densities can be substantially increased, the magma fuel cell may find numerous applications in magma tap projects to increase the efficiency of energy extraction from magma sources or may provide the energy necessary for the electrochemical protection of the heat exchanger materials placed in the corrosive magma environment.

Sealed storage cask concept. Cask closure concept evaluation. Interim report (open access)

Sealed storage cask concept. Cask closure concept evaluation. Interim report

A program was conducted to evaluate four candidate storage cask closure configurations. Four major areas were evaluated to provide a basis for selection of an acceptable closure(s). These were: (1) weldability, (2) suitability of available nondestructive examination methods for determining weld soundness, (3) closure configuration structural soundness, and (4) economics. A relative ranking of each closure configuration was made using the study results. The corner weld configuration was ranked as the most desirable, followed by the threaded plug and seal weld, the circumferential butt-weld and the multiplate in order of decreasing desirability. This report recommends that the structural analysis be continued on the first and second ranked closures to provide a quantitative evaluation capability of their structural integrity and that ultrasonic examination of the corner weld closure configuration be demonstrated. A remote demonstration of welding and nondestructive examination capability of the corner weld is also recommended.
