SEPARATION PROCESS OF LONG-LIVED FISSION PRODUCTS FROM HIGH-LEVEL RADIOACTIVE WASTES

摘要

As the technique of recovering Pd, Se, Cs and Zr ofthe elements containing long half-lived fission productsfrom high-level radioactive wastes, electrolytic,adsorption and solvent extraction methods are selected.In this presentation, recovery of Pd and Se by electrolyticmethod and adsorption and elution behavior of Cs fromnitric acid and simulated high-level liquid wastes areinvestigated, and the concept of facility using thesetechnique is reported.
