Oxidative Dissolution of Uranium Dioxide and Triuranium Octoxide in Carbonate Media
Oxidative dissolution of powdered UO 2 and U 3 O 8 samples in Na 2 CO 3 /NaHCO 3 –H 2 O 2 solutions was studied. The U 3 O 8 samples were prepared from UO 2 at 480–1200°С. The rate and degree of the U 3 O 8 dissolution depend on the characteristics of the oxide powder and on the dissolution temperat...
