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. Its decommissioning is being managed by Nuclear Restoration Services.

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.
