ABSTRACT:
A solidified radioactive waste manufacturing apparatus comprises a first system for producing radioactive waste powder from liquid radioactive waste and a second system connected to the first system for mixing the radioactive waste powder with a thermosetting resin and additives. The first system includes a liquid radioactive waste storage tank, a dryer for drying the liquid waste into powder, and a metering device for supplying a predetermined amount of the radioactive waste powder to the second system and the second system includes a mixer connected to the metering device for mixing the waste powder with the thermosetting resin and additives, a thermosetting resin storage tank, additive storage tanks, a cooler for cooling the mixer, and a container for receiving sludged mixture from the mixer. The additive storage tanks contain a polymerization initiator, a polymerization promotor, and a polymerization retarder, respectively.
