Sampling and characterization of sodium-water reaction products
Sodium-water reaction products (SWRP) which had accumulated in the bottom of the reaction products tank (RPT) of the Large Leak Test Rig (LLTR) were sampled and characterized. Analysis showed that the SWRP consisted of NaOH, Na/sub 2/O, NaH, and Na, as expected, in varying proportions. The unreacted sodium in the samples examined ranged from 32 to 60% by weight. The SWRP reacts (dissolves) rapidly and completely with ethanol, and somewhat less rapidly and completely with Dowanol PM. A magnetic, metallic residue was left, originating in the Croloy of the test article in the LLTR. These solvents should be investigated further as possible agents for cleaning sodium systems that are highly contaminated with water reaction products. The SWRP does not completely liquefy with heating to 800/sup 0/F (427/sup 0/C). Although it softens to a consistency similar to that of wet sand, it is unlikely that it would flow or could be pumped even at such elevated temperature. The presence of highly corrosive molten NaOH. (above 606/sup 0/F, 319/sup 0/C) also makes the hot draining of SWRP unattractive.

Field electrochemical measurements of corrosion characteristics of materials in hypersaline geothermal brine
A flow cell (with appropriate accessories) was developed for use in short-term testing of the corrosion behavior of materials in approximately 100{sup 0}C, hypersaline geothermal brine. The apparatus was designed to accommodate commercial (Petrolite) corrosion measurement equipment and conducted experiments on-line at the Lawrence Livermore Laboratory Test Station in the Salton Sea Geothermal Field. The apparatus also permitted direct readings of corrosion potentials, solution redox potential (E{sub h}), brine flow rate, pH, and temperature. Estimates of general corrosion rates were obtained by the linear polarization resistance technique and from measurements of complete potentiodynamic polarization curves. The latter also afforded predictions of pitting susceptibilities of active-passive type materials. Twenty-two alloys (with various heat treatments) were tested and readily grouped according to general corrosion resistances in acidified hypersaline (approximately 4 M chloride) brine. Especially promising in regard to corrosion resistance-vs-cost is the series of low Cr--Mo steels. Prescaling of materials in unacidified (pH approximately 5.7) brine prior to exposure to acidified (pH 2 to 4.5) brine was found to be beneficial in reducing corrosion rates at 100{sup 0}C.

Materials evaluation for geothermal applications: turbine materials
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.
