The Magnox sites in the UK have now all moved into a phase of decommissioning, which begins with removal of the remaining spent fuel, referred to as “defueling”. Fuel is removed from the reactors and then stored on-site, a process lasting several years. As was the case in the generation phase, ultimately this fuel is transported off site in flasks to the Sellafield site in Cumbria for reprocessing. Once the fuel has been sent off site, 99% of the site’s radioactive inventory is removed. It is the most important hazard reduction activity on our reactor sites and a crucial step in the transition towards decommissioning.
