Abstract (en)
[origin: EP2919237A1] In a radioactive waste solidification method, radioactive waste (for example, zeolite to which Cs-137 was adsorbed) and glass raw materials (soda lime glass) are supplied into the solidifying vessel (3). The solidifying vessel (3) filled with the radioactive wastes and glass raw materials is disposed in an adiabatic vessel (7). A lid is attached to the adiabatic vessel (7) to seal it. The radioactive waste and glass raw materials in the adiabatic vessel (7) are heated by thermal energy generated due to radiation emitted from Cs-137. The glass raw materials are melted and osmose in clearances among the radioactive waste, producing a vitrified radioactive waste. Since the radioactive waste and glass raw materials are disposed in the adiabatic vessel (7), they are uniformly heated and a uniform vitrified radioactive waste is obtained. No melting facility is needed. The radioactive waste solidification method can produce a uniform vitrified radioactive waste through uniform heating without having to use a melting facility.
