Possible causes of the occurrence of radioactive contamination irremovable by acid-base regeneration of ion-exchange resins used in treatment of process media and liquid radioactive waste have been studied. It has been found that most of the irremovable cesium radionuclides are bound to inorganic deposits on the surface and in the bulk of ion-exchange resin granules. The nature of inorganic inclusions has been investigated on real and model spent ion-exchange resins (SIER). A method has been proposed for decontaminating SIER using resorcinol-formaldehyde resins selective to cesium radionuclides. Such an approach has been shown to be promising for deep decontamination of SIER. [ABSTRACT FROM AUTHOR]
