Development of a technology for protecting groundwater from 137Cs on the territory of the BN-350 reactor facility

Resumo

The ability of clinoptilolite from the Chankanai deposit to take up ¹³⁷Cs from groundwater and liquid radioactive waste from the BN-350 reactor facility on the territory of TOO MAEK-Kazatomprom in Kazakhstan was studied. The results of semicommercial tests demonstrate the efficiency of using clinoptilolite as a reagent material of the geochemical barrier for preventing the radionuclide migration into groundwater in case of leakage of tanks for storage of liquid radioactive waste. A design of the geochemical barrier was suggested.
