The present study deals with the survey of inorganic ion-exchangers suitable for separation and immobilization of Sr and Cs contained in acidic high-level liquid waste. For separation and immobilization of Cs, crystalline silicotitanate seems to be the most promising exchanger. For selective separation of Sr, there is no promising exchanger up to now. Sintered ceramics are favorable waste forms of inorganic ion-exchangers. Their stabilities are largely influenced by composition of exchangers, qualities of ceramics and disposal scenario.
