Cesium radionuclides not removable by regeneration are bound to silicate deposits.
Application of RFR substantially increases cesium desorption from an ion-exchanger.
The radwaste volume was reduced at least 2-fold for zeolites and 10-fold for SIER.
The distribution coefficient values for RFR were high (Kd > 104) after 6 regenerations.
The volume of secondary waste formed after regeneration of RFR was reduced 600-fold.
