PREPARATION OF URANIUM OXIDES WITH DIFFERENT DENSITIES (in French)

Journal Article · · Energie nucleaire
OSTI ID:4309557
The oxides of uranium obtained by the three processes used in industry (by precipitation of the peroxide UO/sub 4/, precipitation of the ammonium uranate (NH/sub 4/)/sub 2/U/sub 2/O/sub 7/, and thermal decomposition of the nitrate UO/sub 2/(NO/sub 3/)/sub 2/) are compared on the basis of their apparent densities. The specific gravity varies from 1.5 to 4.5 according to the operating conditions. The oxide UO/sub 3/, the most dense, is obtained by rapid decomposition of uranyl nitrate. The same procedure can be used for the production of light oxides by the introduction of ammonia into the decomposition apparatus. (tr-auth)
