Site information
NRS is a wholly owned subsidiary of the NDA responsible for safely decommissioning ten first-generation nuclear sites at Berkeley, Bradwell, Chapelcross, Dungeness A, Hinkley Point A, Hunterston A, Oldbury, Sizewell A, Trawsfynydd and Wylfa, and two research sites at Harwell and Winfrith, while operating one hydro-electric power station at Maentwrog.
As a division of NRS, Dounreay is responsible for the clean-up and demolition of the former centre of fast reactor research and development.
Over the next decade, as they are defueled, advanced gas-cooled reactor sites at Hunterston B, Dungeness B, Hinkley Point B, Torness, Heysham 1 & 2, and Hartlepool will join NRS for decommissioning.
While decommissioning is the current task at hand, NRS is also working hard to future-proof the organisation by investing in its workforce, assets, communities, sites, and surrounding landscapes to ensure it leaves a sustainable nuclear legacy.
