摘要:
A cold crucible induction melter includes an induction coil and a melting furnace. The induction coil serves as a water cooled segment to directly transmit an induced current to a molten material in the cold crucible induction melter (CCIM), improving energy efficiency. Simultaneously, the structure of the CCIM is simplified and enables a smooth discharge even when the molten material consists of a ceramic or a metal material with a high melting point. The cold crucible induction melter heats and melts waste using an induced current which is generated in a water cooled segment by a high frequency current that is applied to the induction coil. The water cooled segment and the induction coil are disposed in a vertical direction so that the induced current that is generated by the induction coil is directly transmitted to the molten material.

An apparatus and method for the granulation of radioactive waste in which a preprocessing method for the vitrification of radioactive waste is simplified to conform to onsite conditions of a nuclear power plant, additives are improved, and pellets suitable for vitrification are manufactured. The apparatus for the granulation of radioactive waste includes: a body frame having an inlet and an outlet; a hopper supplying the radioactive waste to be transferred and fed through the inlet; a feeder transferring/supplying the radioactive waste supplied to a specific position and in a certain quantity; a stirrer pulverizing/mixing lumps of the radioactive waste supplied; an additive supply part supplying a lubricant to the radioactive waste fed into the stirrer; and a pellet press pressing the radioactive waste fed through the feeder into a pellet shape and discharging the pellet through the outlet.

An apparatus for vitrification of a spent resin containing transition metals, and a method thereof are disclosed. The apparatus includes a crucible melter comprising upper and lower chamber, a wastes-frit input port positioned at a center of the upper chamber, a plurality of oxygen injectors slantly protruding from the upper and lower surfaces of the upper chamber, and being uniformly spaced a predetermined distance from each other, an ozone sparger penetrating the lower chamber toward an upper center in the lower chamber, an ozone generator positioned at a lower end of the ozone sparger to supply ozone to the ozone sparger, and an oxygen tank connected to the ozone generator. With this construction, it is possible to prevent generation or deposition of metallic alloys and sulfides not in a glass state during vitrification of the spent resin produced from a water purification system of a nuclear power plant.
