Dungeness nuclear power stations

The Dungeness nuclear power stations are a pair of non-operational nuclear power stations located on the Dungeness headland in the south of Kent, England.

Dungeness A is a legacy Magnox power station consisting of two 250 MWe reactors which were connected to the National Grid in 1965 and reached its end of life in 2006.

Dungeness B is an advanced gas-cooled reactor (AGR) power station consisting of two 520 MWe reactors, which began operation in 1983 and 1985. They were the first in a series of AGR reactors to be constructed across the UK. In March 2009, unexpected problems discovered during a maintenance shutdown on unit B21 resulted in the reactor remaining offline for nearly 18 months. In 2015, the plant received upgrades and was given a second ten-year life extension to 2028. In September 2018, as both units were shut down for a scheduled maintenance outage, EDF encountered "significant and ongoing technical challenges" which ultimately led to the announcement of its closure on 7 June 2021.
