Dungeness A had two Magnox reactors, built by The Nuclear Power Group, and was connected to the grid in 1965. Generation ceased on 31 December 2006, and defuelling was completed in June 2012. Dungeness B has two advanced gas-cooled reactors, with the construction contract awarded in August 1965. Reactor 1 first generated power on 3 April 1983, about 13 years behind schedule, and reactor 2 began operation in 1985. Both were permanently shut down on 7 June 2021.
