AIRCRAFT NUCLEAR PROPULSION PROJECT QUARTERLY PROGRESS REPORT FOR PERIOD ENDING SEPTEMBER 10, 1952
Progress is reported on the following studies: circulating fuel aircraft reactor experiment (fluid circuit, reflector coolant. pressure-shell stress analysis. off-gas system); experimental reactor engineering (pumps, valves, heat exchangers, instrumentation, fluid dynamics, technology of fluoride handling): reactor physics (oscillations in the circulating fuel reactor. effect of gas on reactivity): critical experiments (direct-cycle reactor. ARE critical assembly); nuclear measurements (fission cross section of U/sup 234/ and U/sup 236/, total cross section of N/sup 14/); chemistry of high-temperature liquids (fuel mixtures containing UF/sub 4/ and UF/sub 3/, alkali fluoborate systems, differential temperature curve of NaF- ZrF/sub 4/-- UF/sub 4/, x-ray studies of complex fluoride systems, simulated fuel mixture for cold critical experiment, coolant development, hydrolysis and oxidation of fuel mixtures, reaction of fuels with alkali metals); corrosion research (parametric studies of fluoride corrosion. fluoride corrosion in thermal-convection loops, compatibility of BeO with fiuoride mixtures, hydroxide corrosion, liquid-metal corrosion, fundamental corros ion research); metallurgy and ceramics (welding. tests of brazing alloys. reduction of MoS/sub 2/); heat-transfer and physical properties research (viscosity of fuel mixtures, heat capacity of LiOH, thermal conductivity of fluoride salt mixtures. vapor pressure of fuel constituents, convective heat transfer in liquid NaOH, boiling heat transfer in Hg); radiation damage (radiation of fused materials, creep under irradiation); and analytical chemistry (analytical studies of components of fiuoride mixtures analytical studies of impurities in fluoride mixtures, determination of C in ZrF/sub 4/ and Zr--NaF-C mixtures).
