    摘要: A method of processing ion exchange resin radioactive waste, wherein the radioactive waste contains a plurality of fractions of radioactive waste based on density, which may include cation resin waste and anion resin waste, wherein at least one of the plurality of fractions comprises a total concentration of at least one radionuclide, including performing at least one of the following operations (i), (ii) or (iii): (i) separating the at least one of the plurality of fractions from the radioactive waste utilizing a moving freeboard; (ii) separating the radioactive waste into cation resin waste and anion resin waste; or (iii) removing at least a portion of the total concentration of the at least one radionuclide from: the radioactive waste; the at least one of the plurality of fractions separated by the moving freeboard; or at least one of the radioactive waste, the cation resin waste or the anion resin waste.
