METHOD OF RADIOACTIVE ION-EXCHANGING RESINS PREPARATION FOR IMMOBILISATION INTO BULK STRUCTURES Russian patent published in 2009 - IPC G21F9/30 

FIELD: nuclear power production industry.

SUBSTANCE: radioactive ion-exchanging resins preparation for immobilisation into bulk structures. Radioactive ion-exchanging resin is mixed with hard non-organic inert bulk material. After that, during mixing the above mixture is exposed to thermal treatment at the temperature no less than 250°C but not higher than 300°C.

EFFECT: reduction of power consumption, prevention of radioactive ion-exchanging resins products agglomeration after thermal treatment, prevention of radioactive ion-exchanging resins inflammation risk during thermal treatment, prevention of volatile resin and oil compositions formation, simplification of process, increased compatibility of radioactive ion-exchanging resins with cement-like materials after their thermal treatment.
