Current phase: C&M Preparations

Berkeley is located on a 27 hectare Site of Special Scientific Interest (SSSI) on the eastern bank of the River Severn in Gloucestershire. Electricity generation started in 1962 and stopped in 1989. During 27 years of operation the site generated 43 TWh of electricity. The site is currently decommissioning, following the entry of the two reactors into safestore in 2010.

Key near term activities

Some key projects for Berkeley in the near term are completion of the chute silo enabling works and retrievals and continuation of work to retrieve and condition various wastes, including FED, resins and other solid ILW.

The site also plans to decommission and demolish the caesium removal plant (CRP) in 2014 and complete an intermediate storage facility for ILW containers in 2013.


  • Removal and recycling of the remaining 15 boilers (each weighing  325 tonnes) from the site
  • Active commissioning of the sludge retrieval plant for sand and sludge storage tank one in the CRP was completed.
  • Achievement of important regulatory milestones, relating to the retrieval of ILW on-site.


Small and Medium Enterprises (SMEs) are a key link in our supply chain and Magnox is committed to supporting the SME agenda for growth.

Opportunities for contracts and ways to become a supplier are set out in the main Suppliers pages of this website.


Site Stakeholder Groups (SSG) are long-established at each of the Magnox sites and provide an opportunity for stakeholders to find out more about the work being undertaken there.

Independently-chaired, the SSG meets regularly to examine our work, as well as that of the Nuclear Decommissioning Authority (NDA) and regulators. The SSG’s membership includes local councillors, non-governmental organisations and other interested stakeholders.
