Glass, ceramic, and glass-crystalline matrices for HLW immobilisation by Michael I. Ojovan, Sergey V. Yudintsev

“…We briefly overview the utilisation of glasses, ceramics and glass crystalline materials (GCMs) composed of both vitreous and crystalline phases focusing on nuclear waste immobilisation and potential use of some advanced waste forms for incorporation of the rare earth elements (REE) and minor actinide (MA: Am, Cm) fraction of high-level waste (HLW).…”
