PRODUCTION OF URANIUM DIOXIDE MASSES OF ENHANCED DENSITY

Patent ·
OSTI ID:4792996
Uranium dioxide masses with a density of at least 95% of the theoretical density are prepared by sintering solid solutions of substantially stoichiometric UO/sub 2/ and at least 0.5 mol% of a reducible oxide (PuO/sub 2/, CeO/sub 2/, PrO/ sub 2/, TbO/sub 2/, NpO/sub 2/, or AmO/sub 2/) in hydrogen at 1200 to 1550 deg C. The solid solutions are obtained by coprecipitating U and the additivc metal from a solution. (NPO)
