PROBLEM TO BE SOLVED: To provide a radioactive waste liquid solidification agent having a stable solidification property, and preventing the waster liquid in a solidified matter from easily oozing out and the solidified matter from easily being softened regardless of a shape (height) of a storage container of radioactive waster liquid.SOLUTION: The radioactive waste liquid solidification agent comprises a surfactant and an absorbent resin comprising a crosslinked polymer containing a water soluble vinyl monomer and/or a hydrolyzable vinyl monomer that becomes the water soluble vinyl monomer by hydrolysis as an essential constitutional unit. The surfactant has an HLB of 5 to 12 and becomes a solid at 25°C and 10hPa.SELECTED DRAWING: None |
