Advanced Gas Cooled Nuclear Reactor Materials Evaluation and Development Program. Progress report, October 1, 1978--December 31, 1978
Results of work performed from October 1, 1978 through December 31, 1978 on the Advanced Gas Cooled Nuclear Reactor Materials Evaluation and Development Program is presented. Objectives are to evaluate candidate alloys for Very High Temperature Reactor (VHTR) Nuclear Process Heat (NPH) and Direct Cycle Helium Turbine (DCHT) applications, in terms of the effect of simulated reactor primary coolant (helium containing small amounts of various other gases), high temperatures, and long time exposures, on the mechanical properties and structural and surface stability of selected candidate alloys, and selection of materials for future test facilities and more extensive qualification programs. The activities associated with the characterization of the materials for the screening test program, and the status of the simulated reactor helium supply system, testing equipment, and gas chemistry analysis instrumentation and equipment are included. The status of the data management system is presented.

Determination of neutron cross sections and resonance parameters for the stable tellurium isotopes for thallium 205 and for the osmium isotopes. Progress report, October 1, 1978-March 1, 1979. [Summaries of research activities at Denison, University]
Initial measurements by LLL and NBS of the ratio of the /sup 186/Os capture cross section to that of /sup 187/Os near 30 keV, provided a crucial input parameter for use of the Re-Os chronometer to estimate the duration of nucleosynthesis and hence the age of the universe. The resulting estimate of approx. = 20 billion years was much longer than the estimate from the only other method, U-Th dating. The Re-Os chronometer requires, however, not ratios of cross sections measured at laboratory temperatures, but rather the ratio appropriate to the stellar environment in which nucleosynthesis by the s-process occurs. Hence capture from low lying excited states is important. The capture cross section from the 9.75 keV first excited /sup 187/Os state must be calculated using Hauser--Feshbach calculations. These calculations require estimates of level densities, neutron transmission functions (for ground and excited states) and radiative transmission functions. These calculations can be experimentally checked by measurements of the total and inelastic cross sections near threshold. The inelastic experiment is particularly difficult because of the requirement of low background and relatively high efficiency for detection of approx. = 30 keV neutrons. A proton-recoil detector has been developed which appears to provide adequate …

LLL geothermal industrial support program first quarter technical progress report for FY1979
The LLL field brine-scaling test system and a variety of measurement techniques have been used to test a group of eight proprietary additives from eight different companies, a hydroxyethylcellulose previously found to retard silica precipitation, and geothermal sludge as a seeding agent to reduce scaling. For each additive, scaling rates at both 210 and 125/sup 0/C and on three different materials--mild steel, Teflon, and Hastelloy C-276 were measured using test coupons. Sections of steel pipe and perforated screens also were exposed to the treated brine, silica precipitation rates in the effluent brine were measured by means of the electrochemical linear polarization resistance technique. Examination of the pipe secions and chemical analyses of the scales are not complete, thus only preliminary conclusions are reported here. It appears that, although none of the additives effected a dramatic reduction in scaling rates, several decreased the rate of scaling of mild steel at 125/sup 0/C by a factor of 2 to 3. Only hydroxyethylcellulose retards the rate of precipitation of silica in the effluent brine. Scaling rates could not be measured accurately in the seeding experiment because of its short duration, but this brine treatment had the desried effect, at 125/sup 0/C, of reducing …
