two reactors each, and both are currently owned and operated by EDF Energy. Together they produce around 30% of electricity generated in Scotland (Scottish Government, 2012). They both have water-filled ponds for storing spent fuel from their reactors to allow cooling of the fuel before it is transported to Sellafield for storage and reprocessing, or long-term storage. The NDA’s strategy for management of spent AGR fuel is currently under review.
