Process for treating radioactive waste

Abstract

Granular ion exchange resins in a desalter provided in a nuclear power plant are taken out from the desalter as used ion exchange resins when their capacities are lowered. The used ion exchange resins in a slurry state are led to a thin film drier. A rotating shaft provided with rotating blades is inserted in the thin film drier. When the slurry of the used ion exchange resins is led thereto, the rotating shaft is driven to rotate, and the side wall of the thin film drier is heated. The used ion exchange resins led to the thin film drier are heated and pulverized to powder by the action of rotating blades. The powder is taken out of the thin film drier to the outside and shaped into pellets.
