ABSTRACT:
A radioactive waste is solidified by adding a nonionic high molecular flocculant to a slurry containing radioactivated crud to precipitate the crud, concentrate the thus treated slurry and then separating the crud from the slurry, drying said crud, mixing the dried crud with a frit of a low melting point and filling a steel can with the resulting mixture, heating the steel can to sinter and solidify the above described mixture, and sealing a surface of the solidified body in the steel can with a sealing material.
