Abstract

Processing of contaminated water in Fukushima Daiichi Power Plant results in various aqueous secondary wastes. A significant strontium ( 90 Sr) contamination represents one of the key challenges for their management, and we have been developing a new cementing matrix based on calcium aluminate phosphate (CAP) system with reduced water content for such aqueous secondary wastes. In the present study, the interaction of CAP with SrCl2 was investigated to gain insight into the capability of CAP system in Sr immobilisation. It was found that the immobilisation is possible, and the incorporation of Sr appears to be associated with the formation of insoluble phosphate salts. The obtained results also suggest that 1 kg of CAP powders can incorporate 200 g of Sr under tested condition.
