Abstract
This invention relates to a solidifying agent for solidifying radioactive waste, and more particularly to a solidifying-agent composition for solidifying radioactive waste, including alumina cement and a gypsum powder. The solidifying-agent composition including alumina cement and a gypsum powder is capable of effectively minimizing an increase in the volume of a solidified radioactive waste product to a level satisfying physical and chemical safety regulations upon the solidification of radioactive waste.
Claims5
A method of solidifying radioactive waste, comprising the steps of:
- (1) adding a fluidizing agent and water to radioactive waste and performing stirring;
- (2) adding a solidifying-agent composition comprising alumina cement, and a gypsum powder, and a defoaming agent to the radioactive waste containing the fluidizing agent and the water added in the step (1) and performing stirring;
- and
- (3) curing the radioactive waste containing the solidifying-agent composition added in the step (2).
