Numerical study of the NOL large-scale gap test

The NOL large-scale gap test has been modeled numerically using the LASL reactive hydrodynamics code 2DE with Forest Fire burn rates. The model gives good agreement between calculated and experimental critical gap values for VTQ-2 and Composition B. The calibration of peak pressure in the gap versus gap length has been obtained from these calculations, and is in good agreement with the published experimental curve. The two-dimensional nature of the gap test is evident from the curvature of the … more

Use of molybdenum ion source electrodes at RTNS-II

Reports are reported for an ongoing effort to optimize D+ beam production by the MATS-III ion source used at RTNS-II. The three seven-aperture electrodes, originally consisting of water-cooled copper, have now been tested using uncooled molybdenum and with water cooling on the second (decel) electrode only. Details of the change, the results of the testing, and the benefits in operation, performance and cost are given.

Evaluation of an all-glass, evacuated, tubular, nonfocusing, nontracking solar collector array. First annual progress report, July 1, 1976--August 31, 1977

A spaced, evacuated tubular radiation receiver employing a highly selective absorber surface and light enhancement features has been subject to extensive test and analysis. Air was used as the heat transfer fluid. The design, installation, test and analysis of the air cooled collector was conducted. The thermal performance of the air cooled collector was found to be better than predicted when rated on an all day operating basis. The high performance characteristic is enhanced by the features of… more

Conductor qualification tests for the 30-MJ Bonneville Power Administration SMES coil

The 30-MJ energy storage coil for the Bonneville Power Administration requires a low-loss, cryostable conductor that is able to carry 4.9 kA in a field of 2.8 T and will maintain its properties over 10/sup 8/ partial discharge cycles. The multi-level cable which satisfies these requirements has been extensively tested at various stages in its development and in its final form. Tests have been performed to determine the effect of manufacturing options on ac losses, low temperature electrical res… more

Conceptual design of a superconducting magnet coil for the large coil program. [Flat-wound NbTi coils]

A conceptual design for a toroidal field (TF) coil for a six coil test array has been developed. The electromagnetic, cryogenic, structural, manufacturing, quality assurance and verification testing requirements have been analyzed. The bore is oval shaped and is 2.35 meters horizontally and 3.35 meters vertically. The coil is designed to operate at 8T peak field at rated current of 10450 amperes when the other 5 coils in the toroidal array are at 80% rated current. Using-flat-wound NbTi conduct… more

Thermal energy storage for power generation

Studies strongly indicate that the United States will face widespread electrical power constraints in the 1990s, with most regions of the country experiencing capacity shortages by the year 2000. In many cases, the demand for increased power will occur during intermediate and peak demand periods. Much of this demand is expected to be met by oil- and natural gas-fired Brayton cycle turbines and combined-cycle plants. While natural gas is currently plentiful and reasonably priced, the availabilit… more

Design and operation of an inert gas facility for thermoelectric generator storage

While the flight hardware is protected by design from the harsh environments of space, its in-air storage often requires special protection from contaminants such as dust, moisture and other gases. One of these components, the radioisotope thermoelectric generator (RTG) which powers the missions, was deemed particularly vulnerable to pre-launch aging because the generators remain operational at core temperatures in excess of 1000 degrees centigrade throughout the storage period. Any oxygen perm… more

LLL total flow geothermal program: summary of two-phase nozzle tests for scale control and materials performance

A series of nozzle and wearblade tests to evaluate scale control and materials performance under total flow nozzle inlet conditions and simulated turbine blade environments was completed using Magmamax No. 1 well fluid. Brine acidification was effective in preventing scale in nozzles and on wearblade flow surfaces. Acid consumption measurements indicate that acid cost will be less than 2 mills/100 lb. brine. Measured erosion rates were low and the results indicate that available materials will … more

Radiation dosimetry through spectral definition

We have developed a fieldable instrumentation system for determining from measured flux spectra, both the neutron and gamma ray dose rate distributions associated with radioactive sources. This system includes the sensors, the computer-based data acquisition and analysis hardware, and the requisite software for unfolding the sensor response functions to obtain the flux spectra, and for folding the resultant flux spectra with appropriate flux spectrum-to-dose conversion factors. We use bismuth g… more

Development of BEACON technology. Quarterly report, April-June 1982

The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Experiments were continued this quarter with the objective of improving the carbon deposition efficiency using a Paraho retort off-gas mixture. Analysis has shown that the use of the Paraho off-gas to make hydrogen would be att… more
