ABS>Results of this investigation indicated that an oxidation-leaching process for uranium recovery from zirconium-uranium is not practicable. Oxidation of zirconium-uranium alloy specimens was sufficiently rapid that the elements would be completely converted to the oxides in about 6 hr at 1000 deg C. However, uranium recovery in leaching was of the order of 80% in the best cases. Tolerable losses are of the order of 0.05%. Oxidative processing of this type of fuel was therefore abandoned. (auth)
