Glass is a non-crystalline solid, as such, it is relatively easy to change its composition to control its characteristics. The borosilicate glass, which is produced by the addition of boron oxide into sodium-lime glass, possesses excellent heat-resistant properties and mechanical strength. It has a wide variety of uses. The borosilicate glass is applied as the vitrified medium for radioactive wastes to immobilize and stabilize them for long term. The glass form which is loaded with high-level radioactive waste is called the vitrified waste. This paper classified the radioactive waste and describes treatment and production methods of vitrified waste, its characteristics, disposal method and also introduces alternative vitrified medium.

The thermodynamic approach is applied in various industrial fields. In this presentation, the glass, which is used as a vitrification medium for the radioactive waste, is highlighted to discuss its appropriate composition, melting temperatures, etc., from the viewpoint of the computational science. Furthermore, the characteristics of iron phosphate glass, will be analysed. For this study, as the database relevant to the target glasses is established, it was also introduced.
