Experiments to determine the oxidation rate, particle size distribution of oxide, and release of I/sup 131/ from one kilogram, trace irradiated uranium slugs oxidizing at temperatures up to 1000 deg C in air and carbon dioxide are described. The release of iodine as a result of rapid melting of uranlum ls also investigated. lt is concluded that extenslve release of elemental lodlne as vapor ls always accompalned by extensive oxidation and that for temperatures below the melting point the release of elemental iodine as vapor is greater for oxidation in air than in carbon dioxide. It is stressed that for the geometrical arrangement and gas velocities used the greater part of the iodine inventory of the uranium remains contained in or adsorbed on particles of uranium oxide.
