STUDY ON SPENT ION EXCHANGE RESIN DRYING AND OPTIMIZATION OF ITS CONDITIONING PROCESS WITH NO INCLUSION INTO THE DISPOSAL MATRIX

JOURNAL: 2022, 19, p. 25-34

ANNOTATION:

The publication [1] discusses technical issues faced during the conditioning of intermediate- and low-level spent ion exchange resins by thermal vacuum drying to obtain packages that would meet waste acceptability criteria for near-surface disposal facilities. This article is a continuation of another publication [1] which elaborated on a study of ion-exchange resin drying process and provided some proposals on the conditioning optimization using NZK-150-1.5 P containers. It specifies optimal parameters for the pre-disposal treatment and conditioning of dried resins providing their safe storage and disposal. The study presents calculated permissible internal pressure providing adequate strength of the containers. The proposed pre-disposal ion exchange resin treatment and conditioning method can be recommended for industrial use.

Keywords: spent ion exchange resins, drying, reinforced concrete container, disposal, radioactive waste.
