Geothermal aquaculture project: Real Property Systems Inc. , Harney Basin, Oregon

Real Property Systems Inc., (RPS) owns two parcels in the vicinity of Harney Lake, Oregon. One parcel is 120 acres in size, the other is 200 acres. A study concludes that the 200 acre parcel has the greater potential for geothermal development. RPS is interested in an aquaculture operation that produces fresh water prawns, (Macrobrachium rosenbergii) for the market. To supply the heat necessary to maintain the ideal temperature of 82/sup 0/F desired for these prawns, a geothermal resource having a 150/sup 0/F temperature or higher, is needed. The best estimate is that 150/sup 0/F water can be found from a minimum 1090 feet depth to 2625 feet, with no absolute assurances that sufficient quantities of geothermal waters exist without drilling for the same. This study undertakes the preliminary determination of project economics so that a decision can be made whether or not to proceed with exploratory drilling. The study is based on 10 acres of ponds, with a peak requirement of 2500 gpm of 150/sup 0/F geothermal water.

High-temperature, solid oxide electrolyte fuel cell power generating system. Annual report, June 1, 1980-May 31, 1981 (open access)

High-temperature, solid oxide electrolyte fuel cell power generating system. Annual report, June 1, 1980-May 31, 1981

Closed-end tubes are now being prepared in-house, for use in fabricating and evaluating the FBA cell design. New perovskite-type mixed oxides are being investigated as air electrode materials and some have been identified and are being used in FBA cell test evaluation studies. Initial FBA cells have been fabricated and tested. Although their performance is below target goals, fabrication procedures for all fuel cell components have been verified for cell construction. Areas of investigation for FBA cell performance improvement have been identified and work is proceeding in these areas. Variable-length cells in the series-cell stack design have demonstrated high (85%) fuel utilization with good performance (0.57 anti V at 400 mA/cm/sup 2/ average, simulated coal derived fuel, 1000/sup 0/C).

Hybrid wood-geothermal power plant, Wendel-Amedee KGRA, Lassen County, California. Identification of environmental issues, second phase

GeoProducts Corporation and the California Department of Water Resources have jointly proposed to develop a 55 MWe power plant in Lassen County, California. The proposed power plant is unique in that it will utilize geothermal heat and wood fuel to generate electrical power, the first attempt to utilize these resources together on a commercial scale. This report identifies requirements for new environmental information that must be generated for permit applications and for preparation of environmental documents required by CEOA and NEPA; presents a schedule for generating new environmental data, for preparing and submitting permit applications, and for obtaining permits; presents a budget for permitting, licensing and environmental assessments as required by applicable laws, regulations and procedures; and investigates the step needed to qualify for a Small Power Plant Exemption by the State Energy Commission.

Pelletized waste form demonstration program, October 1980-March 1981 (open access)

Pelletized waste form demonstration program, October 1980-March 1981

During the last six months, performance testing of waste/cement pellets was continued. These evaluations included leachability tests and compressive strength tests of cold soil/cement pellets of various compositions. Fractional leach rates (g/cm/sup 2//day) after 21 months of testing were, in all cases < 1 x 10/sup -5/ g/cm/sup 2//day (Mound Acceptance Value). Based upon these recent data, the pressed waste/cement pellets appeared to be a suitable matrix for the immobilization of low-level transuranic wastes. The installation of the Carver custom pellet press was completed. Plutonium-238 contaminated (< 100 nCi/g) ash/cement pellets were produced at a rate of 360 pellets/hr. Pellets of two different compositions were produced, 50% ash/50% cement and 65% ash/35% cement. The compressive strength of sample pellets was slightly lower than expected. Static MCC-1 leachability testing as well as long-term radiolysis testing of sample pellets are scheduled.

Investigation of the molecular mechanism of thermal tolerance in bacillus subtilis. Final report, August 15, 1980-August 14, 1981 (open access)

Investigation of the molecular mechanism of thermal tolerance in bacillus subtilis. Final report, August 15, 1980-August 14, 1981

We have studied Bacillus subtilis, Bacillus pumilus and Bacillus caldolyticus to ascertain the molecular mechanism of the ability to growth at high temperatures. B. subtilus wild type strains grow in minimal salts medium at a mesophilic temperature (37/sup 0/C) but not at a thermophilic temperature (56/sup 0/C). However, they do grow at 56/sup 0/C in complex rich media. Analysis of their nutritional requirements revealed that these bacteria require pyridoxine or aspartic acid and threonine to grow at 56/sup 0/C indicating that they are temperature sensitive mutants. Furthermore, mutants of B. subtilis which are able to grow on minimal salts media at 56/sup 0/C can be readily isolated. Therefore, it appears that the lack of growth of the wild type strain in minimal salts media at 56/sup 0/C is due to the instability of an anabolic enzyme. In contrast to B. subtilis, B. pumilus has never been observed to growth above 50/sup 0/C. However, our studies show that mutants of B. pumilus and B. subtilis which grow at 68/sup 0/C can be easily isolated. The isolation of such mutants strongly supports the idea that one gene can determine the ability to grow at extreme temperatures.

Catalysts for upgrading coal-derived liquids. Quarterly report, October 1-December 31, 1980

A linear relationship represents the hydrogenation activity decay of catalysts used in four experimental runs reported previously. The weight percent hydrogen in the reactor product oils plotted against oil-catalyst contact time for experimental runs ZBB, ZBC, ZBD, and ZBE reveals a linear decay rate of 0.0083 wt% hydrogen per hour. This is one quantitative measure of catalyst activity decay. The data for the plot incorporate three different catalysts or combinations used to process a PAMCO liquid at 1500 psig, 435C and LVHST of 2 hours. The data set covers run duration of up to 120 hours of oil-catalyst contact. An air driven hydrogen compressor was installed in the Catalyst Life Test Unit to reduce the costs associated with bottle hydrogen. Minor repairs were made on the oil feed pump. Five experimental runs were made with Shell 324 NiMo/Al catalyst using two feedstocks: (1) 40 wt% EDS/EDS raw solvent and (2) 30 wt% SRC-I creosote oil. The EDS feed oil proved to be rather easily hydrotreated as evidenced by 82 to 100% nitrogen removal, essentially complete desulfurization and no catalyst activity decay during 260 hours of continuous operation. Rapid coking resulted from the highly hydrogen deficient SRC/creosote mixture. The Shell 324 …

Helium generation in fusion reactor materials. Progress report, October-December 1980

Helium analyses have been initiated for the helium accumulation dosimetry materials irradiated in the neutron characterization experiment at RTNS-II. Analyses of the separated isotopes of molybdenum irradiated in the RTNS-I, RTNS-II, and Be(d,n) neutron fields are in progress. The emphasis during the present period was on improving the gas mass spectrometer sensitivity for these samples.
