METHOD FOR EXTRACTING MOLYBDENUM FROM URANIUM OXIDE FUEL Russian patent published in 2000 - IPC

Abstract RU 2153721 C1

FIELD: production of medical molybdenum isotope. SUBSTANCE: for producing Mo-99 isotope, irradiated target based on uranium oxide fuel is dissolved in molten chloride salt by chlorinating agent, molybdenum is volatilized in the form of fraction of highly volatile oxychlorides and chlorides free from basic fission products, mentioned fraction is entrapped as a whole, then melted and refined, and molten salt is used for producing uranium dioxide by electrolysis. EFFECT: reduced amount of wastes and increased yield. 3 cl, 1 tbl
