Preliminary analysis of gravity and aeromagnetic surveys of the Timber Mountain Area, southern Nevada
Recent (1977 to 1978) gravity and aeromagnetic surveys of the Timber Mountain region, southern Nevada, have revealed new details of subsurface structure and lithology. The data strongly suggest that deformation caused by volcanic events has been accommodated along straight-line faults combining in such a fashion as to given a curvilinear appearance to regional structure. The magnetic data suggest that rock units in the central graben and along the southeast margin of Timber Mountain may have been altered, perhaps thermally, from their original state. The gravity data indicate that the south part of the Timber Mountain is underlain by relatively dense rock possibly intrusive rock, like that which crops out along its southeast side. The gravity data also suggest that the Silent Canyon caldera may extend considerably south of its presently indicated southern limit and may underlie much of the area of Timber Mountain. The moat areas appear to be more rectangular or triangular than annular in shape. The southern part of Timber Mountain caldera is separated from the Yucca Mountain area to the south by a triangular horst. The structural relations of the rock units making up the horst are complex. Several linear terrain features in the southern part of …

Preparation and evaluation of advanced electro-catalysts for phosphoric acid fuel cells. Eighth quarterly report, October-December 1981. [Platinum]
In the development of new and highly efficient porous electrocatalysts, two cooperative phenomena are required. The first is an increase in the electrocatalytic activity of the catalyst particle, and the second is the availability of that electrocatalyst particle for the electrochemical reaction. These two processes interact with each other in such a way that improvements in the electrochemical activity must be coupled with improvements in the availability of the electrocatalyst for reaction. Since cost effective and highly reactive electrocatalysts have been developed under this program, the utilization of the electrocatalyst particles in the porous electrode structures is addressed. Based on the performance of the electrocatalysts in porous electrode structures, it is shown that a large percentage of the electrocatalyst in anode structures is not utilized. This low utilization translates directly and dramatically into a noble metal cost penalty for the fuel cell. Dramatic improvements in the cost effectiveness of the fuel cell will be achieved by improvements in electrocatalyst catalyzation technology and electrode structure technology.

Pulsed power -- Research and technology at Sandia National Laboratories
Over the past 15 years, steady and sometimes exciting progress has been made in the hybrid technology called Pulsed Power. Based on both electrical engineering and physics, pulsed power involves the generation, modification, and use of electrical pulses up to the multitrillion-watt and multimillion-volt ranges. The final product of these powerful pulses can take diverse forms--hypervelocity projectiles or imploding liners, energetic and intense particle beams, X-ray and gamma-ray pulses, laser light beams that cover the spectrum from ultraviolet to infrared, or powerful microwave bursts. At first, the needs of specific applications largely shaped research and technology in this field. New the authors are beginning to see the reverse--new applications arising from technical capabilities that until recently were though impossible. Compressing and heating microscopic quantities of matter until they reach ultra-high energy density represents one boundary of their scientific exploration. The other boundary might be a defensive weapon that can project vast amounts of highly directed energy over long distances. Other applications of the technology may range from the use of electron beams to sterilize sewage, to laboratory simulation of radiation effects on electronics, to electromagnetic launchings of projectiles into earth or into solar orbits. Eventually the authors hope to use …

Silicon-germanium/gallium phosphide material in high power density thermoelectric modules. Final report, February 1980--September 1981
This is the final report of work on the characterization of an improved Si-Ge alloy and the fabrication of thermoelectric devices. The improved Si-Ge alloy uses a small addition of GaP in n- and p- type 80 at.% Si-20 at.% Ge; this addition reduces the thermal conductivity, thereby increasing its figure of merit and conversion efficiency. The thermoelectric devices fabricated include multicouples intended for use in Radioisotope Thermoelectric Generators (RTGs) and ring-type modules intended for use with nuclear reactor heat sources. This report summarizes the effort in the material as well as the device areas and discusses individual phases of each area. Results should form basis for further effort.

Solar energy at Sandia National Laboratories
Basic concepts for using the energy of the sun have been known for centuries. The challenge today, the goal of the Department of Energy`s National Solar Energy Program is to create the technology needed to establish solar energy as a practical, economical alternative to energy produced by depletable fuels--and to use that solar-produced energy in a wide variety of applications. To assist the DOE in this national effort, Sandia sponsors industrial and university research and development, manages a series of technical programs, operates solar experimental facilities, and carries out its own scientific and engineering research. This booklet describes their projects, their technical objectives, and explains how their experimental facilities are used to find the answers we`re seeking. Prospective participants from companies involved in solar-energy development or applications should find it especially useful since it outlines broad areas of opportunity. Projects include: central receiver technology; line-focus thermal technology; photovoltaic systems technology; wind turbine development; energy storage technology; and applied research in improved polycrystalline materials for solar cells and photoelectrolysis of water.

Study of selected off-gases produced during the immobilization of nuclear wastes in the SYNROC process. Final report for year ended December 31, 1981. [Pollucite, CsAlSi/sub 2/O/sub 6/, and barium-cesium hollandite, (Ba,Cs)Al/sub 2/Ti/sub 6/O/sub 16/]
Calculation of possible off-gases expected during the fabrication of SYNROC showed that volatilization of cesium would be a significant problem. Samples of the cesium containing minerals pollucite, CsAlSi/sub 2/O/sub 6/, and barium-cesium hollandite, (Ba,Cs)Al/sub 2/Ti/sub 6/O/sub 16/, were prepared for vaporization studies. Fifteen vaporization runs were made with the hollandite samples. With dry air as the carrier gas, the vapor pressure of cesium over Ba/sub 0/ /sub 8/Cs/sub 0/ /sub 4/Al/sub 2/Ti/sub 6/O/sub 16/ was found to be about 1 x 10/sup -7/ atm at 1050/sup 0/C.

Thermal stability of ferritic alloys for fossil-fuel processing systems. Final technical report, September 1, 1978-August 31, 1981. [at 475/sup 0/C]
This research program has investigated the thermal stability of several ferritic stainless steels containing 15 to 18 weight percent chromium over the temperature range 400/sup 0/C to 550/sup 0/C where the 475/sup 0/C embrittlement reaction is of concern. A major part of the experimental work was concerned with the effect of ternary additions of up to 6 weight percent; aluminum on the kinetics and the magnitude of the embrittlement reaction. The work also included a binary Fe-18Cr alloy, a ternary Fe-18Cr-2Mo, and two commercial alloys, Armco type 430 and type 18SR. Resistometric studies of the kinetics of microstructural instability indicated that aluminum additions promote the tendency of chromium atoms to cluster at temperatures in the vicinity of 475/sup 0/C. The magnitude of embrittling reaction is intensified by the aluminum additions which are expected to restrict dislocation cross slip and increase the coherency strains associated with the alpha prime precipitates. Activation energy determinations for the decomposition reaction indicate that the rate controlling process is most likely determined by the diffusion of chromium, and the tendency of aluminum to enhance the clustering of chromium atoms is similar to the effect reported for molybdenum additions by previous workers.
