Abstract
Cement mortars and compounds prepared in the course of the development of a process for solidification of the solution fraction of alkaline high-level waste (HLW) accumulated at the Mayak Production Association were studied. Only materials commercially available in Russia were included in dry mix formulations. The spread, bleeding, final setting, and heat release were determined for model inactive cement mortars, and the compression strength, frost resistance, and water resistance, for the compounds. The 137Cs leach rate was determined for the cement compounds with real solidified high-level solutions. The formulation meeting the whole set of regulatory and technological requirements to cemented radioactive waste, provided that the compound is placed in limited-volume containers (e.g., in NZK-type containers), was developed.
