Vitrification of intermediate level radioactive waste by induction heating

Vitrification of intermediate level liquid and solid radioactive wastes is an effective method of their immobilization. A new type of melter -- cold crucible -- suitable for production of high fusible materials has been developed. No refractories and internal electrodes are used in this melter. Based on the preliminary experience of SIA Radon with lab-scale and pilot plants, the full-scale plants for vitrification of liquid and solid radioactive wastes have been constructed. The main process variables such as melt capacity, melting ratio, cesium volatilization as well as materials properties have been determined. Advantages of cold crucible over Joule heated ceramic melter have been shown. Process flow sheets have been described
