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.
