DEVELOPMENT OF A CONDITIONING TECHNOLOGY FOR SPENT ION EXCHANGE RESINS

JOURNAL: 2018, 2, p. 54-61

AUTHOR: A.S. Savkin

ANNOTATION:

In FSUE «RADON» various methods of treatment and conditioning of radioactive spent ion-exchange resins (IER) were
tested. Evaluation of technological appropriateness of the methods according to the following criteria: conformity to
requirements of normative documents, the specific activity of IER, the presence of a certified package, the capacity of
the installation was done. Selected criteria correspond dewatering, inclusion in the polymer matrix, and cementation.
A technical and economic comparisons of the selected technologies were performed. The full-scale pilot plant for
the dewatering, and the inclusion of IER in the matrix material directly into a container for disposal was designed,
manufactured and tested on a real IER. For the subsequent introduction of industrial plants at nuclear power facilities
working documentation for the experimental — industrial plant for conditioning IER directly in the container was
developed. The choice of container depends on the specific activity of IER (KMZ, NZK–150–1.5 P).

Key words: ion exchange resin, nuclear power plants, polymer binder, dewatering, and cementation.
