Processes for recovering both ²³³U and thorium from irradiated thorium oxide or thorium metal were adapted and modified as required for use in the existing Savannah River facilities that are normally used to process enriched uranium-aluminum alloy. In the resulting process, ²³³U and thorium are separated and purified by solvent extraction with 30 vol % tributyl phosphate. The ²³³U is subsequently concentrated by cation exchange and converted to uranium trioxide.
