Progress on energy analysis of geothermal resources is reported. The power curve for a vapor dominated hydrothermal plant is shown. (MHR)

In the large fusion program at Livermore we are actively doing research in most areas of inertial confinement fusion. The areas in which we are funded for research specific to heavy ion fusion are: (1) target design; (2) energy conversion chamber design and (3) ion beam propagation in the combustion chamber. There are two main thrusts to the target design effort: (1) development of targets which are optimally suited to heavy ion fusion power production and (2) fundamental studies of the beam-target interaction.

The Rio Blanco Massive Hydraulic Fracturing Project was fielded in 1974 as a joint Industry/ERDA demonstration to test the relative effectiveness of MHF in the same formations that were stimulated by the Rio Blanco nuclear fracturing experiment. The project is essentially a companion effort to and a continuation of the preceding nuclear stimulation project, which took place in May, 1973. The well was fractured a total of four times, twice in the Upper Mesaverde and twice in the Fort Union. A fifth zone in the Upper Mesaverde was extensively tested but abandoned as being of insufficient quality for fracturing. In the four treatments, none appears to have fractured laterally as designed. In the Fort Union and Mesaverde each well must produce from numerous sand lenses, the lateral extent of which appears to be limited.

TERA Corporation presents the results of a detailed seismic risk analysis of the Battelle Memorial Institute's Nuclear Research Facility at West Jefferson, Ohio. This report focuses on earthquakes.

This report presents the results of a detailed seismic risk analysis of the Nuclear Materials Development Facility (NMDF) operated by Atomics International at Santa Susana, California. The historical seismic record was established after a review of available literature, consultation with operators of local seismic arrays and examination of appropriate seismic data bases including the USGS, California Institute of Technology and NEIS data bases. The resulting seismic record, covering the period 1969 to 1977, was used to identify all possible sources of seismicity that could affect the site. The best estimate curve indicates that the facility will experience 30% g with a return period of 55 years and 60% g with a return period of 750 years.

TRW is designing a system for the demonstration of the Solar Production of Industrial Process Steam. Included, besides the Conceptual Design, is an Environmental Impact Assessment and a System Safety Analysis report. The system as proposed and conceptualized consists of an array of 9520 square feet of parabolic trough concentrating solar energy collectors which generate pressurized hot water. The pressurized water is allowed to flash to steam at 300 psi (417/sup 0/F) and fed directly into the high pressure steam lines of the Ore-Ida Foods, Inc., processing plant in Ontario, Oregon. Steam is normally generated in the factory by fossil-fired boilers and is used by means of a steam-to-oil heat exchanger for the process of frying potatoes in their frozen food processing line. The high pressure steam is also cascaded down to 125 psi for use in other food processing operations. This solar system will generate 2 x 10/sup 6/ Btu/hr during peak periods of insolation. Steam requirements in the plant for frying potatoes are: 43 x 10/sup 6/ Btu/hr at 300 psi and 52 x 10/sup 6/ Btu/hr at the lower temperatures and pressures. The Ontario plant operates on a 24 hr/day schedule six days a week during the …

The project conceptual design activities are divided into six parts: Industrial Plant, Conceptual System Design, Collector Selection, Heat Transfer Fluid Selection, Site Fabrication, and Engineered Equipment. Included is an overview of the solar steam system and a brief discussion on the environmental impact of the project as well as the safety considerations of the system design. The effect of the solar system on the environment is negligible, and the safety analysis of the system indicates the considerations to be taken to minimize any potential safety hazard due to contamination of the food product or to fire. Both of these potential hazards are discussed in detail. Both the question of product contamination and the question of potential fire hazards will be presented to the industrial partner's safety committee so that the selection of the heat transfer fluid meets with their approval.
