Abstract
PURPOSE: To simplify disposal facilities, by mixing all radioactive waste matters from nuclear fuel reprocessing facilities with one another and changing the mixture into dry powder.
CONSTITUTION: Waste liquids of low and medium levels produced in the separation process and extraction process of the nuclear fuel reprocessing facilities are introduced into a waste liquid vessel 1. If the concentration of volatile substances in the waste liquid is high, the liquid is transferred into a sludge vessel 2 and removed of the volatile substances by cohesive sedimentation. The waste liquids of low and medium levels, sludge in the sludge vessel 2, waste resin in a waste resin vessel 3 and ash in an ash vessel 4 are mixed with one another in a disposal vessel 5. The pH level of the mixture in the disposal tank 5 is kept neutral by the ash containing calcium oxide as main constituent. The neutralized mixed slurry is conducted from the disposal vessel 5 to a centrifugal film drier 7 which changes the slurry into the dry powder. The powder is made into pellets by a granulating machine 11. The pellets are solidified with asphalt 12 in a drum can 14.
