【报告摘要】

Vitreous materials in form of both homogeneous glasses and glass composite materials incorporating crystalline disperse phases within a durable vitreous matrix are currently the most reliable wasteforms effectively used on industrial scale for nuclear waste immobilisation. Glasses are solid state materials with a topologically disordered atomic structure which can be considered as true solid solutions i.e., solutions being frozen via vitrification to a solid state without phase separation.
Nuclear waste vitrification is attractive because of technological and compositional flexibility enabling hazardous elements to be safely immobilised providing a glassy material characterised by high corrosion resistance, mechanical and radiation durability, as well as effectively reducing the volume of the resulting wasteform. Borosilicate and aluminophosphate glasses are the overwhelming world-wide choice for the immobilization of high-level radioactive wastes (HLW) resulting from used nuclear fuel reprocessing and low- and intermediate level radioactive wastes (LILW) such as the radioactive waste arising from the operation of nuclear power plants and from the decommissioning of nuclear facilities. Vitrification is a mature technology which has been used on an industrial scale for more than fifty years. Continued advances in devising durable vitreous wasteforms and improving nuclear waste vitrification technologies provides key solutions in enabling widespread deployment of nuclear energy.
