4. Vitrification

4.1 Vitrification of nuclear waste

Since the early days of the French nuclear power industry, vitrification has been developed for the long-term containment of radioactive waste from spent fuel reprocessing. . At the end of the cycle, waste with a high radioactive load needs to be processed, and solidification aims to obtain a solid form that is safe for long-term containment, such as geological disposal. The technical and economic conditions and safety requirements are specific to the case of radioactive waste. In this case,...
