REJECTED NUCLEAR FUEL RECOVERY PROCESS Russian patent published in 2000 - IPC

Abstract RU 2154313 C1

FIELD: manufacture of pelletized nuclear fuel. SUBSTANCE: rejected fuel having different mass fraction of U235 in mixture of isotopes is processed to obtain U3O8 oxide with desired mass fraction of U235. In addition, rejected nuclear fuel having different mass fraction of U235 in uranium isotope mixture is recovered; in order to obtain nominal mass fraction of U235 in uranium isotope mixture ingredients having different mass fraction of U235 in uranium isotope mixture are calculated from relevant formula, delivered in metered portions, and mixed up without milling, and then mixed up again in the course of thermal oxidizing simultaneously with oxidizing process until U3O8 oxide powder is obtained. EFFECT: facilitated procedure. 1 dwg
