High-temperature of thermodynamic properties of sodium

Description: The set of high-temperature thermodynamic properties for sodium in the two-phase and subcooled-liquid regions which was previously recommended, has been modified to incorporate recent experimental data. In particular, replacement of the previously estimated critical constants with experimentally-determined values has resulted in substantial differences in the region of the critical point. The following thermodynamic properties were determined: pressure, density, enthalpy, entropy, internal ener… more

Evaluation of the radionuclide concentrations in soil and plants from the 1975 terrestrial survey of Bikini and Eneu Islands

Description: In June 1975 a radiological survey was conducted of the terrestrial environment of Bikini and Eneu islands (Bikini Atoll) to evaluate the potential radiation dose to the returning Bikini population. In this report, we present measurements of the radionuclide concentration in soil profiles and in dominant species of edible and nonedible, indicator plants. The use of these data to derive relationships to predict the plant uptake of radionuclides from soil is described. Approximately 620 soil and … more

Geothermic model for the rise of deeper groundwater along faults in unconsolidated rocks

Description: A simple model was derived which may be used to explain measured temperature anomalies in areas of unconsolidated rock containing faults. It is assumed that deep groundwater rises along the path provided by the faulting. The calculations were performed using temperature data from the Niederrhein--Bucht. The model yields a quantitative relationship between the vertical flow of groundwater and the temperature anomalies observed. The primary results indicate that the quantity of water flow require… more

Tritium storage development. Progress report No. 13, July--September 1977

Description: Engineering-scale operation was started on hydriding of zirconium for application to tritium storage systems. Eight runs were made with commercial-grade zirconium sponge at 338/sup 0/ to 499/sup 0/C and 0 to 770 torr, hydrided to hydrogen-to-zirconium atom ratios up to 2. Reaction rates were determined for hydrogen flow rates of 2.72 to 9.24 cm/sup 3/ at STP/g Zr-min. For each run, hydrogen pressure was plotted on a semilog scale against time and H/Zr atom ratio to elucidate the reaction mechan… more

Improvement and Verification of Fast Reactor Safety Analysis Techniques. Progress Report, October 1, 1977--December 31, 1977

Description: The critical superficial vapor velocity was measured for an open vessel system with chemically produced internal heat. The measured value was within experimental error of the value predicted by the Kutateladze stability criterion. The greatest error induced was in the measurement of the energy generation rate. The effects of mixtures were taken into account. Further work suggestions are also presented.

Chemical heat pump: a simple means to conserve energy. Final report, September 1, 1976-February 28, 1977

Description: This is the final report of a six-month preliminary investigation into the applicability of the Chemical Heat Pump (CHP) for day-and-night, heating-and-cooling of residences with solar energy. The CHP consists of two containers and a joining conduit. Its working mechanism is the reversible absorption of water vapor onto a dessicant such as powdered magnesium chloride dihydrate in one container, the reversible evaporation of water in the other container, and the reversible passage of water vapor… more

Experimental high temperature coefficients of compressibility and expansivity of liquid sodium and other related properties

Description: The subcooled compressibility of liquid sodium was directly measured up to 200 atm between 900 K and 1867 K, utilizing a new multi-property apparatus which was previously tested with water. The experimental data were correlated by a 6-term equation with a standard deviation of 9.2 percent. The equation can be used to estimate the subcooled compressibilities and densities of liquid sodium up to 2300 K and 500 ata. The thermal expansion of liquid sodium was also measured along the isobars 1 ata, … more

Cabibbo current and CP violation in a six quark gauge model

Description: The extended Cabibbo current in a six quark gauge model is obtained in terms of Eulerian angles theta/sub c/, phi and psi which are functions of quark mass ratios and phases in the quark mass matrices. Particular attention is paid to arbitrary phases that lead to CP violation. In the limit m/sub u//m/sub c/ ..-->.. 0 there is no CP violation for parallel ..delta..S parallel = 1 processes. Some phenomenological results of the model are discussed.
