“…11 The downside of this kind of vitrification is the partial release of Cs due to its volatile nature, as demonstrated by Charpin et al, who showed that, during vitrification, aggregated nanoand micro-sized particles containing Cs are formed in the melter. 12 Activated carbon exhibits a good nuclear waste adsorption capacity, and due to their properties, metal-organic frameworks (MOFs) also show excellent potential for the removal of lanthanides and actinides. MOF is a relatively new material that consists of an inorganic core with metal ion centres connected to organic ligands forming a branched network.…”

Nuclear energy production generates nuclear waste. Nuclear and radioactive waste, especially high level waste (HLW) and intermediate level waste (ILW), require special long-term safe management solutions. One part of the solution involves recycling through reprocessing of spent nuclear fuel. Recycling reduces the volume of nuclear waste and allows for the reuse of some of its components. This can be achieved through methods such as adsorption, ion exchange, coagulation, flotation, filtration, chemical precipitation, reverse osmosis, and solvent extraction, like the PUREX process. Another possible future solution involves partitioning and transmutation technology, which can reduce the production of nuclear waste. The best long-term solution is the immobilisation of HLW and ILW in a solid matrix. Materials used for this purpose include glasses, cements, bitumen, geopolymers, concrete, and ceramics as a promising material. While cementation is still the most commonly used immobilisation method due to its low cost and simplicity, vitrification is a more permanent long-term solution. Deep geological disposal in combination with vitrification and a robust multi-barrier system is considered the most acceptable solution for safe nuclear waste isolation. This review provides insight into the mostly commonly used and promising immobilisation materials, as well as the most effective methods and technologies currently in use and under development for the management of HLW and ILW in nuclear waste management.
