Abstract
Isotopic hydrogen-deuterium effects down to eutectic temperatures in saturated halide and nitrate solutions have been investigated by means of Rayleigh distillations and solubility determinations. A thorough study of the fission-fragment-induced emission of uranium atoms from uranium metal and dioxide has been concluded. Supplementary and new experiments were performed in various atmospheres and at different pressures, and the results and mechanism theoretically interpreted. In order to study the energy transfer mechanism the heterogeneous system n-hexane/silica gel was irradiated with a y-ray source. The products formed were identified by gas chromatography and ESR spectroscopy and their G-values determined. New and efficient methods of separating mixed fission products from an acid and highly active waste solution containing large amounts of uranyl nitrate are required for the reprocessing of plutonium-enriched fuel elements by amine extraction. As part of a project to achieve this separation by eutectic freezing the ternary phase diagram of simulated waste solution was studied and solubilities were determined at low temperatures. Work on the separation of fission products of interest by means of inorganic ion exchangers has also been carried out. The properties and affinities of zirconium phosphates and zirconium silicate phosphates were studied. It was shown that high loads of
