The extraction of actinides and other constituents from highly active waste (HAW) by trialkyl phosphine oxide (TRPO)
The removal of the actinides U, Pu, Am, Cm and Np from highly radioactive waste (HAW) would reduce the radiological hazard of the HAW. TRPO (trialkyl phosphine oxide), an industrial solvent for uranium extraction, has good solvent behaviour, high radiolytic stability and low cost. The extraction of actinides and other HAW constituents by 30 vol% TRPO in paraffinic diluent from both simulated and real HAW is studied. The loading capacity of the TRPO solvent is also reported, and compared with data for the TRUEX solvent.
