Dungeness A Nuclear Power Station
of Romney Marsh
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]
1965 Dungeness 'A' is a Magnox power station, that was connected to the National Grid in 1965. 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.
1965 September. 'Dungeness “A” Nuclear Power Station of the Central Electricity Generating Board yesterday started to deliver power to the grid. It is the C.E.G.B.’s fifth nuclear power station to go into service. The station has a total output capacity of 550,000 kilowatts. At present only the first reactor is operating, but number two reactor is expected to be in service within the next few weeks.'[2]
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 the 'care and maintenance' stage of decommissioning in 2027.
