Abstract

Results from tests of technology for decontaminating spent radioactive ion-exchange resins at the Balakovo and Kalinin nuclear power stations are presented. Versions of technological schemes with cleaning and repeated use of decontaminating solution are considered. The possibility of considerably reducing the volume of radioactive wastes is demonstrated.
