METHOD OF TREATMENT OF METAL RADIOACTIVE WASTE formed by reprocessing pressurized water reactors and RBMK

摘要

1. A method of processing radioactive metal waste generated during reprocessing of nuclear fuel pressurized water reactors and RBMK, comprising chlorination of waste and the separation of the products obtained, characterized in that, in order to minimize the volume and transfers most of their parts in other, safer, categories are chlorination with molecular chlorine at a temperature of 400-500 ° C, and calcine filtered dustable products directed to Purex process, a gas mixture for purification of niobium and other alloying elements of brabatyvayut hydrogen at a temperature of 450-550 ° C and passed through a ceramic filter is then heated to 500-550 ° C, the purified zirconium tetrachloride is crystallized in the condenser at a temperature of not higher than 150 ° C.2. A method according to claim 1, characterized in that purified zirconium tetrachloride is used to produce a volatile at normal temperatures zirconium compound to separate its isotopes and polucheniyaZr as desired product.
