FIELD: technological processes.
SUBSTANCE: invention relates to technology of processing radioactive wastes, in particular used ion-exchange resins. Method of processing spent ion-exchange resins, comprising treating the resin with an oxidant while heating, characterized in that the process of dissolving the resin is carried out in an orthophosphoric acid medium with periodic introduction of an oxidant or an oxidative mixture into the reaction medium at temperature of 110–120 °C and continuous stirring.
EFFECT: invention enables complete destruction of the high-molecular structure of the ion-exchange resin with an oxidant or an oxidative mixture and obtaining a solution which preserves aggregate stability at temperature of 25–120 °C for a long period of time.
