1963. Under construction.

Located on a 91 hectare site on the Kent coast in an area of SSSI. Two power stations are located on the site - Dungeness A and Dungeness B

Dungeness A occupies about a quarter of the site. Dungeness B Nuclear Power Station occupies the rest of the site, with its Advanced Gas Cooled reactors.[1]

Dungeness A is a legacy Magnox power station, that was connected to the National Grid in 1965 and has reached the end of its life. It possessed two nuclear reactors producing 219 MW of electricity each, with a total capacity of 438 MW. The construction was undertaken by a consortium known as the Nuclear Power Group (TNPG). The reactors were supplied by TNPG and the turbines and gas blowers by C. A. Parsons and Co. AEI supplied the main alternators.

On 31 December 2006 the 'A' station ceased power generation, having produced a lifetime output of 120 TWh. Defuelling was completed in June 2012 and the demolition of the turbine hall was completed in June 2015. It is expected to enter 'care and maintenance' stage of decommissioning in 2027
