Abstract

In treatment of aqueous solutions and suspensions of radioactive waste through a step of drying and pulverizing the aqueous solutions and suspensions and a successive step of compressing and solidifying the resulting powders of radioactive waste, a step of measuring a water content of the powders is provided between the step of drying and pulverizing and the step of compressing and solidifying. When the measured water content of the powders fails to satisfy a predetermined water content, the powders are eliminated from a system of the treatment without passing through the step of compressing and solidifying.
