摘要:
AbstractMaterials capable of trapping alkali metal vapors at temperatures up to 800°C were tested and a number of surface-active mterials proved efficient. A sufficient quantity of Molecular Sieves, activated alumina or activated carbon can be contained in a crucible cover to trap and hold the evolved alkali metal vapors from an EBR-II melt refining furnace charge of 10 kg. The cover design is under development.

摘要:
AbstractMelt refining experiments in which irradiated uranium or synthetic EBR-II alloys were melted in oxide crucibles have shown that removal of zirconium as an oxide does not occur at temperatures up to 1400°C. Removal of zirconium by carbon scavenging of the melt was approximately 50% in 5-hr melts at 1400°C; the mechanism and products of reactions which lead to this separation are discussed. Zirconium contamination of uranium-cerium alloys melted in lime-stabilized zirconia crucibles was negligible.

摘要:
AbstractMelt refining of synthetic EBR-II alloy in stabilized zirconia crucibles at 1400°C for three hours under one atmosphere of helium pressure resulted in almost complete volatilization of iodine from ingot and skull fractions. Removal of iodine was strongly dependent on refining temperature. Volatilized products were primarily iodides of metals initially present as minor oxide constituents of the crucible; no evidence for evaporation as free iodine was found in the melt refining operation.

摘要:
AbstractRuthenium, molybdenum, palladium, rhodium, technetium, and antimony are retained by the bulk metal when uranium containing macrolevels of accompanying fission elements is melt-refined in oxide crucibles at 1200–1400°C. Under similar conditions, cadmium and tellurium are nearly quantitatively removed, the latter element by a proposed mechanism involving the formation of a stable compound with cerium.
