Abstract

The efficiency of uranium and plutonium oxides extraction via recrystallization from a simulated spent nuclear fuel (SNF) using molybdenum compounds as a flux is presented. A novel process scheme, incorporating the dissolution of SNF in molten molybdenum trioxide MoO3, peritectic decomposition of uranyl molybdate and plutonium(IV) molybdate Pu(MoO4)2 to yield the respective oxides, and subsequent washing with molten sodium molybdate Na2MoO4 is proposed and justified.
