摘要:
A radioactive waste is treated by supplying a liquid concentrate of at least one of a radioactive liquid waste and a radioactive waste slurry to a centrifugal film dryer, thereby drying and pulverizing insoluble and soluble solid matters contained in the concentrate, washing the centrifugal film drier with hot water after the drying and pulverization, settling the effluent washing water together with a condensate containing solid matters generated in the drying and pulverization, and supplying a slurry of insoluble solid matters separated by the settling to the centrifugal film drier, thereby drying and pulverizing the solid matters. The dried powder from the centrifugal film drier can be pelletized in a pelletizer, and effluent washing water generated by washing the pelletizer with hot water after the pelletization can be subjected to the settling together with the effluent washing water and the condensate from the centrifugal film drier. Operating load of the centrifugal film drier is considerably reduced, and the operating efficiency and life of the centrifugal film drier are improved thereby.

A vent gas containing radioactive iodine and methyliodide is effectively decontaminated by chemically adsorbing the iodine contained in the vent gas onto an activated carbon layer at first, then physically adsorbing the methyl iodide contained in the vent gas onto another activated carbon layer separately disposed from the former activated carbon layer, and retaining the radioactive iodine and radioactive methyl iodide on the respective activated carbon layers for a definite period of radioactive decay.
