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.

Teratology studies of lewisite and sulfur mustard agents: Effects of lewisite in rats and rabbits: Final report
Lewisite was administered to rats and rabbits by intragastric intubation. Maternal animals were weighed periodically, and, at necropsy (20 dg (days of gestation) in rats and 30 dg in rabbits), were examined for gross lesions of major organs and reproductive performances; live fetuses were weighed and examined for external, internal and skeletal defect. In rats, a dose level of 1.5 mg/kg did not induce toxic or teratogenic responses in maternal and fetal body weights and a significant reduction in the number if viable fetuses were evident. In rabbit studies maternal mortality occurred in all but one of the lewisite treatment groups and ranged from 13% to 100% at dose levels of 0.07 and 1.5 mg/kg, respectively. This mortality rate limited the sample size and impaired the detection of statistical significance among treatments. However, at the lowest dose level of the teratology study (0.07 mg/kg, maternal mortality was the only indicator of lewisite toxicity; at the highst dose (0.6 mg/kg), significant findings included 86% maternal mortality, a decrease in maternal body weight gains and an increase in the incidence of fetal stunting, although only a tendency in decreased fetal body weights was observed. These results suggest that maternal mortality was the …

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.

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.

Preliminary design of the Carrisa Plains solar central receiver power plant. Volume III, Book 1. Design description
The design of the 30 MWe central receiver solar power plant to be located at Carrisa Plains, San Luis Obispo County, California, is summarized. The plant uses a vertical flat-panel (billboard solar receiver located at the top of a tower to collect solar energy redirected by approximately 1900 heliostats located to the north of the tower. The solar energy is used to heat liquid sodium pumped from ground level from 610 to 1050/sup 0/F. The power conversion system is a non-reheat system, cost-effective at this size level, and designed for high-efficiency performance in an application requiring daily startup. Successful completion of this project will lead to power generation starting in 1986. This report discusses in detail the design of the collector system, heat transport system, thermal storage subsystem, heat transport loop, steam generation subsystem, electrical, instrumentation, and control systems, power conversion system, master control system, and balance of plant. The performance, facility cost estimate and economic analysis, and development plan are also discussed.
