In 2022 Hunterston B will be the first of EDF’s nuclear power stations to end generation and start decommissioning. Later in 2022, Hinkley Point B will join its sister station in the first phase of decommissioning - defuelling.
By 2030, EDF expects all of the seven AGR stations to have ended power generation and to be at various stages of decommissioning. Only one of the existing stations - Sizewell B (a pressurised water reactor) - will still be generating low carbon electricity.
On behalf of Government, EDF’s job will be to remove all the used fuel from the reactors and fuel ponds, which represents over 99% of the radioactive material from each site.
Once the two reactors are emptied of fuel, deconstruction involves removing all plant, equipment, services and buildings external to the reactor building. Early decommissioning preparation will start during defuelling, such as waste preparation activities.
