The idea of glass being a suitable matrix for the immobilization of nuclear waste was proposed in 1950s. Since then, vitreous waste forms have been the most widely accepted candidates for the immobilization of high-level nuclear waste (HLW) worldwide. While several countries are in the process of vitrifying their HLW, the others are still in the planning phase or starting in the near future. Although the general matrix of HLW glasses remains the same, i.e., borosilicate, the overall design of glass compositions is different worldwide primarily due to the different waste chemistries, thus resulting in different scientific and engineering challenges. The lecture will present a historical perspective of the high-level waste vitrification followed by its current status and future challenges at a global level.
