Comparison of costs of purifying radioactively contaminated water by sorbents of multiple-and single-use

Abstract

The investigations of the expenditure in the purification of radioactively contaminated water make it possible to plan the paths to be followed in subsequent investigations on the synthesis and selection of sorbents and also on the development of methods of solidifying and burial of wastes. 1. A search for cheap single-use sorbents with isotope separation capacity exceeding the capacity of regenerable sorbents at least by a factor of two. 2. Production of regenerable sorbents with such a capacity that would ensure purification of more than 300–500 m3 of solution per 1 m3 of sorbent. 3. Development of cheaper burial processes.
