Continuous fusion solidification treatment for radioactive waste and its device

Creators

Description

Purpose: To permit solidification treatment of a radioactive waste such as concentrated liquid waste, used ion exchange resin, ash, laundry waste and liquid waste of decontamination by using a thermoplastic resin such as polyethylene. Constitution: The radioactive waste is preliminarily dried to reduce the water content to such an extent that scattering of the radioactive substance and generation of powdery dust no longer take place, and then it is dried up to the absolute dry state through removal of water vapor and gas by suction. The radioactive waste which is thus dried in this way and a thermoplastic resin such as polyethylene are mixed together, and the mixture is fused and then dried. (Aizawa, K.)
