Radiation Resistance of Sorbents for Recovering Cesium from High-Level Alkaline Waste

Abstract

The radiation-chemical resistance of Fersal, RFR-i, RFR-Ca, and Clevasol sorbents was determined. The effect of the absorbed dose on the ¹³⁷Cs distribution coefficient in sorption from an alkaline solution simulating the accumulated high-level waste solutions was studied. The sorbent samples were examined by electron microscopy. The mechanism of the degradation and oxidation of the sorbents on heating in air was determined.
