Progress of the LASL dry hot rock geothermal energy project
Under sponsorship of the Division of Applied Technology of AEC, Los Alamos Scientific Laboratory is investigating the possibilities and problems of extracting energy from geothermal reservoirs which do not spontaneously yield useful amounts of steam or hot water. The system for accomplishing this which is being developed first is a pressurized-water circulation loop intended for use in relatively impermeable hot rock. It will consist of two holes connected through the hot rock by a very large hydraulic fracture and connected at the surface through the primary heat exchanger of an energy utilization system. Preliminary experiments in a hole 2576 ft (0.7852 km) deep, extending about 470 ft (143 m) into the Precambrian basement rock underlying the Jemez Plateau of north-central New Mexico, revealed no unexpected difficulties in drilling or hydraulically fracturing such rock at a temperature of approximately 100 C, and demonstrated a permeability low enough so that it appeared probable that pressurized water could be contained by the basement rock. Similar experiments are in progress in a second hole, now 6701 ft (2.043 km) deep, about 1.5 miles (2.4km ) south of the first one. Here the bottomhole temperature is about 146 C, and again no unexpected difficulty was …

Experimental Geothermal Research Facilities study (Phase 0). Final report. Volume 1
Phase 0 of a project for Experimental Geothermal Research Facilities focuses on identification of a representative liquid-dominated geothermal reservoir of moderate temperature and salinity, preliminary engineering design of an appropriate energy conversion system, identification of critical technology, and planning for implementation of experimental facilities. The objectives included development of liaison with the industrial sector, to ensure responsiveness to their views in facility requirements and planning, and incorporation of environmental and socioeconomic factors. The overall project, of which the six-month Phase 0 is reported herein, is phased in accordance with RANN guidelines. This Phase 0 report covers problem definition and systems requirements. Phase 1 will involve design of the experimental facility, and testing of components. Phase 2 will comprise detailed design and construction of an experimental geothermal electrical powerplant at East Mesa, Imperial County, California. Facilities will incorporate capability for research in component, system, and materials technology and a nominal 10 MWe experimental, binary cycle, power generating plant.

Experimental geothermal research facilities study (Phase O). Final report No. 26405-6001-RU-00
This study focuses on identification of a representative liquid-dominated geothermal reservoir of moderate temperature and salinity, preliminary design of an appropriate energy conversion system, identification of critical technology and planning for the implementation of experimental facilities. Results of Phase O of the project are reported in two volumes. Volume II presents detailed results of studies and analyses arranged in nine appendices including the final report by a subcontractor on the study. The specific appendices are: Appendix A: Geothermal Resources of the Western United States; Appendix B: Site Selection Process and the East Mesa Geothermal Field; Appendix C: East Mesa Geothermal Field Reservoir Characteristics; Appendix D: Advisor's Views and Comments; Appendix E: Thermodynamic Analyses; Appendix F: Material and Corrosion Factors; Appendix G: Preliminary Reliability/Maintainability Analyses; Appendix H: Environmental Impact Analysis Guidelines; and Appendix I: Report to the National Science Foundation/TRW Systems Group by Rogers Engineering Company, Inc., San Francisco, California.

Cold trap requirements for PHTS and IHTS sodium purification
Cold trap requirements for the Primary Heat Transfer System (PHTS) and the Intermediate Heat Transfer System (IHTS) are defined. The bases for these requirements are (1) maintaining concentrations of oxygen and hydrogen within given limits, (2) controlling the transport of tritium by coprecipitating it in cold traps together with hydrogen, and (3) providing the necessary volume capacity for collecting impurities. It is concluded that the 60 gpm, FFTF Type I, NaK cooled, cold trap will satisfy the PHTS requirements. For each of the IHTS loops a single, 60 gpm, cold trap is required; and an aircooled trap similar to the FFTF Type I design except for a 3-foot longer crystallizer section has been chosen for this service.

Preliminary safety analysis of the B-C Cribs Controlled Area. [Hanford Reservation]
Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to the ground surface is believed to have been burrowing by an animal (probably a badger) followed by use of the exposed material as a salt lick by rabbits and other animals. When the radioactivity was discovered, the burrow was sealed, the contaminated site was classed as a radiation zone, and surveillance initiated. The contamination site has not been a significant hazard to employees at the plant or to the public. The Atlantic Richfield Hanford Company maintained control over the surface contamination by isolation, zoning, and by continued surveillance. Methods of handling the contaminated area have been considered. Discussions of these alternatives and applicable safety analysis information are included in this document.
