Abstract
1,226,198. Uranium fluorides. KERN FORSCHUNGSANLAGE JULICH G.m.b.H.. 20 Dec., 1968 [21 Dec., 1967], No. 60610/68. Heading C1A. [Also in Division G6] Spent nuclear fuel containing uranium and thorium oxide or carbide is dissolved in an alkali metal compound melt, and the solution is treated to precipitate an alkali metal uranate which is separated and fluorinated to form UF 6. In one embodiment, oxide fuel is dissolved in potassium pyrosulphate melt and solid NaOH is added to form the precipitate; in another embodiment, carbide fuel is dissolved in a NaOH » Na 2 O 2 or a Na 2 CO 3» K 2 CO 3 melt. Fluorination to UF 6 is carried out in a fluidized bed (a) with HF to form UO 2 F 2 and then with F 2 ; (b) with HF mixed with S0 2 or NH 3 to form UF 4 and then with F 2 ; or (c) directly with F 2 .
