THE USE OF PLUTONIUM AS FUEL IN NUCLEAR REACTORS. Quarterly Report No. 5, July 1-September 30, 1961

Technical Report ·
OSTI ID:4144590
Plutonium dioxide, prepared from precipitated oxalate, dissolves easily in a nitric acid-hydrofluoric acid mixture. The effects of iron on the fluorometric analysis of uranium was determined. As regards the potentiometric analysis of plutonium, the choice of indicator electrode, the effects of catalysers, and the reagent addition rate were examined. Plutonium carbide was produced from plutonium dioxide and graphite. By uranium dioxide vibration, densities around 89% of the theoretical density were obtained. By cold swaging densities around 94% of the theoretical density of uranium dioxide and 9l% of the density of uranium carbide were obtained. The zirconium alloy powders produced have a lower hydrogen content than powders obtained commercially. Zirconium and Zircaloy-2 dispersions were fabricated. Dilatometric results were obtained on stoichiometric and substoichiometric plutonium dioxide and plutonium dioxide- uranium dioxide mixtures. The phases of the niobium-zirconium alloys were established. Different chemical baths for polishing niobium-zirconium alloys were tried for their preparation with a view to corrosion tests. Tensile tests on niobium-zirconium alloys were made along with creep tests. A heat conductivity measurement instrument was developed. (auth)
