Method for photochemical reduction of uranyl nitrate by tri-n-butyl phosphate and application of this method to nuclear fuel processing
Patent
·
OSTI ID:6723668
Uranyl ion in solution in tri-n-butyl phosphate is readily photochemically reduced to U(IV). The product U(IV) may effectively be used in the Purex process for treating spent nuclear fuels to reduce Pu(IV) to Pu(III). The Pu(III) is readily separated from uranium in solution in the tri-n-butyl phosphate by an aqueous strip.
