Dungeness, Kent, UK · Operations 1965-2006, Decommissioning ongoing · Part of Magnox Ltd decommissioning budget

The judgement call

Account-gated at launch

Demolition of the turbine hall began in 2015, marking a significant step in the decommissioning process. - The site is well-positioned for the next phase of decommissioning, which involves the removal of remaining buildings. - The decommissioning process is expected to take decades, highlighting the long-term commitment required for nuclear legacy sites.

Key engineering challenges

Decommissioning a Magnox reactor site, including the removal of reactor buildings and associated infrastructure. - Managing radioactive waste and materials in a coastal environment. - Ensuring long-term safety and environmental protection during the extended decommissioning process. - Adapting to evolving regulatory requirements and technological advancements in decommissioning.
