ABSTRACT

This work focuses on the problem of separation of radiocobalt from nuclear power plant evaporator concentrates containing EDTA. The proposed process for the treatment of nuclear power plant evaporator concentrate tested on simulated solution consisted of three steps: 1) boric acid removal from the solution by acidification, 2) elimination of the influence of the presence of organic complexing agent (EDTA) in the solution by its photodegradation, and 3) separation of radiocobalt from the resulting solution. The effect of each of the steps of the proposed process on the distribution coefficients of cobalt sorption on several sorbents (active carbons and inorganic ion-exchangers) was studied. The results obtained confirmed that cobalt separation can be significantly improved by EDTA degradation. Further investigation is necessary to bring the proposed method to the industrially applicable level. More... »
