UK scientists to make nuclear reactor graphite from recycled waste

The University of Manchester is leading a five-year UK research program called ENLIGHT, funded by an $11 million grant from UK Research and Innovation and industry partners, to transform the lifecycle of nuclear reactor graphite. The program involves Oxford, Plymouth, and Loughborough universities and aims to develop technologies for producing sustainable, domestically sourced nuclear-grade graphite and recycling irradiated graphite waste. This initiative addresses the UK's reliance on imported graphite—a key material accounting for about one-third of reactor build costs—and the growing stockpile of over 100,000 tons of irradiated graphite from decommissioned reactors. ENLIGHT supports the UK’s goal to expand nuclear power capacity to 24 gigawatts by 2050 as part of its net zero ambitions. The program focuses on designing new graphite materials that can withstand extreme reactor conditions, improving their lifespan, and converting irradiated graphite waste into a valuable resource. It is expected to save the UK up to £2 billion in future waste management costs, enhance energy security,
