Several options are available to immobilise waste resulting from nuclear fuel reprocessing. One of these is vitrification – a mature technology which has been used for high-level nuclear waste immobilization for over 50 years…Argentina is considering vitrification as a viable option for dealing with its high-level nuclear waste. The Argentine National Programme for Radioactive Waste Management aims to build capacities to implement vitrification processes for radioactive waste….
The vitrified radioactive waste is extremely durable, and ensures a high degree of environmental protection. Although the process of vitrification requires a high initial investment and then operational costs, waste vitrification has important advantages: it significantly reduces the volume of waste, and allows simple and cheap disposal possibilities. The overall cost of vitrified radioactive waste is usually lower than alternative options when transportation and disposal expenses are taken into account. For this reason, the process is very attractive for sates seeking effective and reliable immobilisation solutions for their radioactive waste stocks.
