Abstract
A method is provided for separating trivalent actinides and rare earth elements in the TRUEX method using a CMPO-TBP mixed solvent. The method of separating trivalent actinides and rare earth elements comprises a trivalent actinide/rare earth extraction step wherein trivalent actinides and rare earth elements are extracted by a solvent from highly acid waste generated by reprocessing of spent nuclear fuel, a nitric acid removal step wherein the nitric acid concentration of the solvent used to extract the trivalent actinides and rare earth elements is reduced, and a separation step wherein the trivalent actinides and rare earth elements contained in the solvent of low nitric acid concentration, are separated from each other.
