Dungeness B is situated near Romney Marsh, Kent on the south east coast of England.

Dungeness B is a twin reactor advanced gas-cooled (AGR) station. It was the first commercial advanced gas-cooled reactor to commence construction (1965) and started generating power in 1983. The power station is built on a large area of open shingle, measuring 12 km by 6km. The three small towns on the headland nearest the power station are Lydd-on-Sea, Greatstone-on-Sea and Littlestone-on-Sea, which lie to the north on the east coast of the Dungeness headland.

In June 2021 Dungeness B  announced that with immediate effect  it has ended its generation activities and has now entered the defueling phase  of its life which is expected to take several years.

Dungeness B is operated by the licence holder EDF Energy Nuclear Generation Ltd, a subsidiary company of EDF Energy plc.
