Undeniably, nuclear is an abundant source of energy with potential to address energy security concerns of the entire humanity for a prolonged period of time; but serious attention is required for the eventual elimination of nuclear waste that are piling up in temporary storages. A global stockpile of around 250,000 tonnes of highly radioactive spent fuel are stored across some 14 countries for disposal. The volume is likely to increase soon as many reactors, especially in Europe, due to be decommissioned by 2025. The idea of geological repositories for long-term burial of nuclear waste, though sounds technically feasible, has been a matter of intense public opposition. A prudent alternative, therefore, is to recycle fuel-worthy material that remains in the ‘spent fuel’.
