Progress in a program to determine the effects of UO/sub 2/ dispersion in U metal on its dimensional stability under thermal cycling conditions is reported. Oxidation experiments using 0.002 in. foils of U were conducted in which information concerning handling techniques and the nature of U oxide films was obtained. A trial hydriding run using Fe- U alloy was completed in which 200- and 100-g batches of the alloy were used. The 100-g sample was incompletely hydrided, however, the 200-g sample was ground and hot pressed in vacuum. A second bydriding run was made using U shot. This process and subsequent conversion to U powder proceeded smoothly. A powder oxidation run was made in which 25 g of the hydrided and decomposed U shot was oxidized to test apparatas modifications aimed at loss prevention. Fabrication of the U- 14 wt.% Fe alloy resulted in an unsatisfactory product. Other compacts attained a density equivalent to 90% pure U, which corresponds to approximately 25 wt.% UO/sub 2/.
