A number of candidate turbine materials are being evaluated for their resistance to erosion, corrosion, and stress corrosion cracking (SCC) in geothermal brines. These materials include Fe-, Ni-, Co and Ti-base alloys, coatings and ceramics. Tapered wearblades, simulating the leading edge of a turbine blade, are exposed to the direct impact of a two-phase nozzle exhaust. Bent beam SCC specimens, which are constrained in fixtures attached to the wearblade holders, are also exposed to this exhaust. Results of a test series are reported in which acidified liquid brine was expanded to atmospheric pressure are reported. The tests were performed at the LLL Field Test Station near Niland in the Salton Sea Geothermal Field. Evaluation of the exposed materials indicates that Ti-base alloys show the most promise for turbine wheel components in the high salinity geothermal environments.

Continuing fission cross section ratio studies at Lawrence Livermore Laboratory, one has measured the /sup 232/Th//sup 235/U fission cross-section ratio from 0.7 to 30 MeV. Using the threshold method, one obtained a value of 0.1081 +- 0.0022 for the average cross-section ratio in the interval from 1.75 to 4.00 MeV.

The focus of this research has been centered on the Caltech research tokamak. Somewhat more than half of the effort during the preceding year has been devoted to bringing it into operation, familiarizing ourselves with its characteristics, and to the development of further diagnostics. Concurrently, three experimental studies, one involving the propagation of toroidal magnetosonic modes, one involving drift wave turbulence, and the other involving lower hybrid turbulence are proceeding. Each is described in some detail.

The fluxes of protons emitted during solar flares since 1956 were evaluated. The depth-versus-activity profiles of /sup 56/Co in several lunar rocks are consistent with the solar-proton fluxes detected by experiments on several satellites. Only about 20% of the solar-proton-induced activities of /sup 22/Na and /sup 55/Fe in lunar rocks from early Apollo missions were produced by protons emitted from the sun during solar cycle 20 (1965--1975). The depth-versus-activity data for these radionuclides in several lunar rocks were used to determine the fluxes of protons during solar cycle 19 (1954--1964). The average proton fluxes for cycle 19 are about five times those for both the last million years and for cycle 20. These solar-proton flux variations correlate with changes in sunspot activity.

The presentation contains the results of a literature review of concepts for augmenting the safety of light-water moderated nuclear power plants as alternatives to underground siting. Two types of alternatives were considered. The first type, consisting of alternatives to LWR power production technology such as the high temperature gas reactors (HTGRs), the liquid-metal fast-breeder reactors (LMFBRs), etc., has been previously discussed. The second type, consisting of alternatives within LWR power production technology such as radioactive fission product containment methods, is presented here. The review was restricted to evaluations of the effectiveness of each concept to achieve safety benefits, rather than the necessity for achieving the benefits. For this reason, it was implicitly acknowledged that underground siting was being studied to reduce the consequences of a hypothesized core melt accident. It is generally assumed that such accidents are very unlikely to happen. Nevertheless, a basic tenet of the review was that such an event was possible and underground siting alternatives might be found which were both effective and economically feasible.

Results are reviewed from a number of studies on the biological effects of static and low frequency electromagnetic fields on animals. Based on a long history of experience with electric fields by the utility industry, it appears that intermittent and repeated exposures to strong 60-Hz electromagnetic fields from present power transmission systems have no obvious adverse effect on the health of man. It has been recognized recently that this belief must be tested by carefully designed and executed experiments under laboratory conditions where precise control can be exercised over coexisting environmental factors. A number of studies have been initiated in response to this need to evaluate possible effects from both acute and chronic exposures. 100 references.

The seeded growth furnace with the slotted molybdenum susceptor has been operated during the past quarter. Flat sheets of sapphire were used as the tray, and local cooling at the tin-silicon alloy surface was provided by a symmetric water-cooled jet. The silicon surface growth obtained during the past quarter has been consistently polycrystalline. This poor growth is attributed to impurities in the seeded growth furnace, caused by leakage into the system. Two sources have been identified: deteriorating neoprene O-rings and leaks of cooling water from the jet nozzle. The O-rings were replaced with indium gaskets, and the nozzle is being rebuilt. Weight loss measurements of the sapphire tray plates indicate that they suffer negligible attack by tin-silicon alloy melts at 1000/sup 0/ to 1100/sup 0/C. The growth habit of crystals nucleated spontaneously at the tin-silicon alloy melt surface has been studied. The crystal growth observed is consistent with dendritic and web growth from (111) singly twinned triangular nuclei. Examples of planar surface growth of small (less than 0.1 mm), thin crystals from these twinned surface seeds have been observed.

The purpose of the study is to provide an engineering evaluation of high and low temperature LMFBR core designs. The study was conducted by C-E supported by HEDL expertise in the areas of materials behavior, fuel performance and fabrication/fuel cycle cost. The evaluation is based primarily on designs and analyses prepared by AI, GE and WARD during Phase I of the PLBR studies.

The electrode behavior of the system, Ca/aq.-NaOH, NaCl, was investigated at ambient temperatures. Limiting currents were noted for intermediate concentrations of NaOH and NaCl, while rapid passivation at high ratios of NaOH to NaCl occurred. Low ratios of NaOH/NaCl yielded uncontrollable hydrogen evolution and rapid calcium dissolution. A model of the aqueous cell of the proposed system for the production of lithium was completed. The apparatus allows simultaneous determination of current efficiency and electrode polarization for the Li(Hg)/aq.-LiOH electrode upon cathodic polarization. Cooling curves indicate the existence of a LiI--KI--LiCl eutectic with a melting point of approximately 230/sup 0/C; possible errors are being considered arising from artifacts of the system and possible impurities in the salts. 2 figures.

Growth of channel catfish (Ictalurus punctatus) and Tilapia zillii in the Reft River Geothermal Area (RRGT) geothermal waters can equal or surpass that in a commercial aquaculture facility. Fish and prawn mortality over the course of the intermediate term preliminary study did not appear to be related to any inherent geothermal water chemistry conditions. Temperature control was a problem but does not appear to be beyond design control. The absence of temperature-related mortality in channel catfish, Tilapia zilli, and yellow perch (Perca flavescens) indicates increased survival and suggests reduced expenditures for disease control. It may also allow higher fish densities in commercial aquaculture operations using geothermal water. Results of this study indicate potential for commercial aquaculture development at the Raft River Geothermal Testing Site.

A study was performed to determine the best method for disposing of waste fluorine in the effluent from a uranium oxide conversion facility. After reviewing the fluorine disposal literature and upon considering the nuclear safety constraints, it was determined that the two most promising processes were the fluidized alumina bed and the caustic scrubber. To obtain more design data for the latter process, a 3-stage, 5-in. I.D. spray tower was constructed and operated. This unit used a 10% potassium hydroxide solution at flows of 1.5 to 3 gpm and achieved a 90% fluorine efficiency at fluorine flowrates as high as 4 scfm. However, two toxic by-products, oxygen difluoride and nitroxy fluoride, were detected in the effluent gases. After considering the relative merits of both disposal processes, it is concluded that the fluidized bed is superior, especially if the contaminated waste material were salable.

The objectives of this research project were to obtain data on the behavior of potentially toxic substances introduced into surface waters from nuclear power plants, determine the impact magnitude of these substances on representative and economically important aquatic species, and the development of models with which to predict the partitioning of these substances among the abiotic aquatic compartments. Results are included from an investigation of copper partitioning in freshwater and seawater, the toxicity of copper to representative marine organisms, and development of a mathematical model to predict copper partitioning.

A device that measures charge-exchange flux to determine the angular distribution of the 2XIIB plasma is described. Charge-exchange products heat circular nickel foils (placed at 15/sup 0/ intervals in theta and at constant radius on an arc parallel to the z-axis) and the voltage drop across the foils (produced by constant-current sources) provides a measure of the changes in resistivity. The charge-exchange flux at each foil is proportional to the plasma distribution at that angle. Use of this technique is limited by the resistivity and heat resistance of the circular nickel foils, but could conceivably be extended to other shapes and materials. The Hall-Simonen and ''time-average'' measurement of angular distribution are compared and the characteristic times of loss (gain) are calculated from theory. The g(..mu..) detector may be used to experimentally verify these times of loss (gain) and also to analyze plasma pressure stability. Current microwave measurements show that plasma has an exponential density dependence in z and assumes a flux tube rather than a p(B) density dependence. A distinct angular distribution (determinable by the detector) is associated with each of these dependencies. The codes to simulate injection and resulting angular distribution, charge-exchange capture, and heating and signal of the …
