Dungeness B is a nuclear power station on the south coast of England. It was the first Advanced Gas-cooled reactor to begin construction in the UK.
- Station Director: Ian Stewart
- Reactor type: 2 Advanced Gas-cooled Reactors
- Total supply to the national grid: 1050 MW
- Coolant: Carbon dioxide gas (CO2)
- Start of construction: 1966
- Start of generation: 1983
- Estimated decommissioning date: 2028
- People: Approximately 550 full time EDF Energy employees, plus over 200 full time contract partners

Nominal full load refers to the nominal maximum generation in megawatts from a reactor. The output from a reactor can fluctuate even when at full load for many reasons (e.g. plant conditions, sea water temperatures, operating limits/constraints etc). Where the output of a reactor is reduced by approximately 10% or more of its maximum, the reason for this will be shown. Generation figures are net of any imports into the station and may be negative when a unit is not generating.
Return to service dates are provided to the same accuracy as provided to National Grid under the requirements of the Grid Code and refer to the first full day of operation. Where a return to service date falls within approximately two weeks of the date of this report, the exact date will be shown. Where a return to service date is expected to fall more than two weeks into the future, the week commencing in which a reactor is due to return to service will be indicated (shown as “w/c”).
Additional information on the availability of our nuclear power stations can be found on our REMIT page.
EDF Energy and Nuclear Decommissioning Authority hold regular joint meetings with local people, media, council and emergency services representatives and local politicians to maintain regular communications about the site. This meeting is independently chaired.
The next site stakeholder meeting will take place on Thursday 11 October 2018 at 10:30hrs at Dungeness B Visitor Centre. For more information contact Tracey Finn, Magnox Ltd, on: 01797 343510
