The proposed project aims to develop a new solidification technique with minimised water content for the safe storage of secondary aqueous radioactive wastes involving highly radioactive Sr and sea components. We implement development of a solidification technique to decrease water content in a waste form by heating, to immobilise Sr and Cl in a phosphate material, and to solidify the waste form by acid-base reaction instead of hydration reaction as well as its stability assessment.
