Characteristics of the site significant to the prospect for geothermal development are described, including: physiography, demography, economy, and the goals and objectives of the citizens as they relate to geothermal development. The geothermal resource evaluation is described, including the depth to reservoir, production rates of existing water wells, water quality, and the resource temperature. Uses of the energy that seem appropriate to the situation both now and in the foreseeable future at Gabbs are described. The essential institutional requirements for geothermal energy development are discussed, including the financial, environmental, legal, and regulatory requirements. The main resource, engineering and institutional considerations involved in a geothermal district heating system for Gabbs are summarized.

The principal goal of this study was to provide analysis of and recommendations on the need for and feasibility of a geothermal reservoir insurance program. Five major tasks are reported: perception of risk by major market sectors, status of private sector insurance programs, analysis of reservoir risks, alternative government roles, and recommendations.

A human factors engineering design review of the Palo Verde control room simulator was performed at the site on September 15 through September 17, 1981. Observed human factors design discrepancies were given priority ratings. This report summarizes the team's observations of the control room design and layout and of the control room operators' interface with the control room environment. A list of the human factors strengths observed in the Palo Verde control room simulator is given.

We have continued our laboratory studies of forward gasification in small blocks of coal mounted in 55-gal drums. A steam/oxygen mixture is fed into a small hole drilled longitudinally through the center of the block, the coal is ignited near the inlet and burns toward the outlet, and the product gases come off at the outlet. Various diagnostic measurements are made during the course of the burn, and afterward the coal block is split open so that the cavity can be examined. Development work continues on our mathematical model for the small coal block experiments. Preparations for the large block experiments at a coal outcrop in the Tono Basin of Washington State have required steadily increasing effort with the approach of the scheduled starting time for the experiments (Fall 1981). Also in preparation is the deep gasification experiment, Tono 1, planned for another site in the Tono Basin after the large block experiments have been completed. Wrap-up work continues on our previous gasification experiments in Wyoming. Results of the postburn core-drilling program Hoe Creek 3 are presented here. Since 1976 the Soviets have been granted four US patents on various aspects of the underground coal gasification process. These patents are …

The results of the analyses as well as a plan for geothermal development are described. The major findings and specific barriers to development that would have to be addressed are identified. Characteristics of the site significant to the prospect for geothermal development are described. These characteristics include physiography, demography, economy, and the goals and objectives of the citizens as they would relate to geothermal development. The geothermal resource evaluation is described. Based on available information, the reservoir is generally described, defining the depth to the reservoir, production rates of the existing water wells, water quality, and the resource temperature. Uses of the energy that seem appropriate to the situation both now and in the foreseeable future at Gabbs are described. The amounts and types of energy currently consumed, by end-user, are estimated. From this information, a conceptual engineering design and cost estimates are presented. Finally, the results of a life cycle analysis of the economic feasibility are discussed. A time-line chart shows the tasks, the time estimated to be required for each and the interrelatioships among the activities. The essential institutional requirements for geothermal energy development are discussed. These include the financial, environmental, legal and regulatory requirements. The main resource, …

This report identified human engineering discrepancies (HEDs) in Callaway-1. It was found that overall the systems reviewed were designed to permit effective and efficient operator actions. The applicant's proposed resolutions of the HEDs are acceptable to the Human Factors Engineering Branch (HFEB) staff. Because of the large number of systems not available for evaluation during the HFEB site visit, a second visit will be required. (DLC)

Assessing proliferation resistance of nuclear power alternatives was central to the Nonproliferation Alternative System Assessment Program (NASAP). Assessment efforts were made by several organizations associated with NASAP. These efforts produced papers and documents which assisted the NASAP program understand the many facets of the proliferation problem and carry out its responsibilities of providing R and D guidance. This report briefly reviews these papers to document the chronology of the process, to observe the evolution of the assessment effort and to identify additional efforts which might be appropriate even though NASAP is complete.

Effort was directed toward the fabrication of a micron-spaced thermionic converter diode. This technique demonstrated that interelectrode spacings down to 1.5 ..mu..m could be obtained. Several methods of duplicating the emitter and collector surfaces were also investigated. Two new techniques are proposed; both stem from an earlier idea of using evaporation, photolithography, and etching techniques. These two fabrication methods yielded a one-piece diode structure with a thick-film copper collector, eliminating the need to physically duplicate the electrode surfaces and realign the electrodes. Effort has also been directed toward a more detailed theoretical analysis of micron-spaced thermionic converter performance. Taking into account heat losses through the interelectrode support structure, it is likely that the maximum energy conversion efficiency may be greatest at a spacing somewhat larger than 1 micron (..mu..m), but less than 10 ..mu..m.

Summaries and updates of sixteen technical reports issued on this project are included. They cover: in depth analyses of the Federal land management-related problems present at major target prospect KGRA's throughout the Pacific Rim States; financial incentives; transmission line access; substantive environmental requirements in air, water, and solid wastes; water law; and the geothermal-impacting activities of the legislative and regulatory agencies of the State of California.

The GROW (Gasification Research on Wood) project consists of a research project on thermochemical degradation of wood particles (sawdust or hammermilled wood) on a pilot plant scale and utilizes a 100 cm (40 in.) diameter fluidized sand bed reactor at capacities of up to 1000 Kg/Hr (2200 lb/hr). Supplementary facilities include wood preparation and air conveying, a wood feed bin, feed and transfer screws, an air compressor with storage and filter tanks, an electrical preheater, a propane-fired preheater, a cyclone separator removing solids from product gas, a water scrubber to cool and clean product gas, a scrubber wate settling tank, a scrubber water cooler, a knockout drum, a demister to be installed in the future, a recycle compressor for recirculation, a recycle gas storage tank, a flare and stack with air blower to dispose of the gas, 2 CO/sub 2/ stripper columns to be installed in the future to remove CO/sub 2/ by caustic adsorption, caustic tanks, and the necessary piping, pumps, sampling, and measurement facilities. A brief report of progress on the project is given, followed by the safety implementation plan and operating, maintenance, and safety procedures. (MHR)
