Application of new ion exchangers at purification plants of nuclear power stations

Czechoslovak ion exchangers were tested as substitutes for imported organic ion exchangers. A technological process for removing radiocesium from the cooling water of spent fuel transportation and storage pools using synthetic zeolites was tested, as was the application of zeolites to the purification of condensate arising during vitrification of Cr(VI) containing anticorrosion solutions, and to the reduction of specific activity of cesium radionuclides in model liquid concentrates. The spent adsorbents can be processed by cementation or vitrification. The composition and basic characteristics of zeolites available in Czechoslovakia are given. (M.D.). 3 tabs., 14 refs
