Consolidation of Spent Fuel and Nuclear Materials. In 2013 we concluded the development of our strategy to remove unirradiated nuclear material from Dounreay and consolidate it at Sellafield. All Magnox stations have now been defueled and the fuel has been consolidated at Sellafield for long-term management. After reprocessing operations at the Thermal Oxide Reprocessing Plant (THORP) ceased, AGR transports have continued and spent fuel from the EDF AGR stations is being consolidated at Sellafield for safe and secure interim storage. We are expecting an increase in the need for AGR transport capacity when the EDF stations stop generating and the reactors are being defueled. Between 2011 and 2013 we took a series of decisions to consolidate exotic spent fuels from Dounreay, Harwell and Winfrith at Sellafield. This includes the 44 tonnes of breeder material from the Dounreay Fast Reactor (DFR), and 11 tonnes of irradiated oxide and carbide fuels, principally from the Dounreay Prototype Fast Reactor (PFR). It also includes fuel originally from the DRAGON reactor at Winfrith which is now being transported from Harwell to Sellafield for encapsulation in the Magnox Encapsulation Plant (MEP). If spent fuels are declared as waste for disposal in a GDF, the inventory currently in interim storage would be packaged and sent to a GDF site. This would happen decades after the AGR stations have finished defueling and would require the spent fuel transport capacity to be increased again after a long pause.
