Magnox Ltd is responsible for the safe and secure clean-up of 12 nuclear sites and one hydro-electric plant's operation.

Under the Nuclear Installations Act 1965, Magnox Ltd is licensed and the licence holder for 12 nuclear sites and one hydro-electric plant. As such, they are the legal entity responsible for the following sites, which the Nuclear Decommissioning Authority owns:

  • Berkeley

  • Bradwell

  • Chapelcross

  • Dungeness A

  • Harwell

  • Hinkley Point A

  • Hunterston A

  • Maentwrog

  • Oldbury

  • Sizewell A

  • Trawsfynydd

  • Winfrith

  • Wylfa


Each site has a Site Stakeholder Group (SSG) or Local Site Liaison Council (LCLC), which acts as a liaison between the local community and the site. Independently chaired, the groups meet regularly to examine our work, as well as that of the Nuclear Decommissioning Authority and regulators. 

Magnox is responsible for ensuring that activities are carried out:

  • safely, securely and predictably, with due regard for the environment

  • to the satisfaction of the Nuclear Decommissioning Authority

  • in the organisation's long-term interests, their employees, the local communities, and the Magnox supply chain partners.

The twelve sites are located at Berkeley, Bradwell, Chapelcross, Dungeness A, Hinkley Point A, Hunterston A, Oldbury, Sizewell A, Trawsfynydd, Wylfa, Harwell and Winfrith. All the sites have ceased production. Also, as part of the Trawsfynydd unit, Magnox Ltd operates a hydro-electric power station at Maentwrog.

The only Magnox power station in the United Kingdom not managed by Magnox Ltd is Calder Hall, which is part of the Sellafield site and is controlled by Sellafield Ltd.
