Feasibility study for industrial conditioning of spent ion-exchange resins by impregnation with a polymer binder

Abstract

A comparative study of technologies for conditioning reprocessed spent ion-exchange resins was carried out by FSUE “RADON” on laboratory and pilot-industrial scales. According to industrial application criteria, a choice was made in favor of dehydration and impregnation using a polymer binder based on epoxy resins. To implement this technology, a pilot unit was developed and manufactured. Tests of the unit carried out with actual resins demonstrated its operability and the compliance of the resulting polymer compound with regulatory requirements.
