Description

Safe handling and disposal of high-level radioactive wastes (HLRW) is the indispensable condition for further development of nuclear power engineering. The most efficient approach to the problem of issue assumes the removal of especially hazardous long-lived radionuclides (namely, 90Sr, 134,137Cs, transplutonium elements) from HLRW, thus transferring the latter into the intermediate-level radioactive waste (ILRW) category. This paper presents the results obtained during the bench and pilot-plant scale tests of the crown-ether- based extraction process for 90Sr and ferrocyanide-containing inorganic ion exchanger-based adsorption process for 134,137Cs removal from HLRW. The data on the HLRW immobilization technique comprising the adsorption of HLRW on an inorganic adsorbent particles at elevated temperature followed by firing them at 800-1000 deg. C are also reported. (author)
