Our role and responsibilities

Magnox Limited, owned by Cavendish Fluor Partnership Limited, is the management and operations contractor responsible for safely managing twelve nuclear sites and one hydroelectric plant in the UK, working for the sites’ owner, the Nuclear Decommissioning Authority (NDA).

Magnox are responsible for managing the sites through their lifecycles, overseeing all aspects of defuelling and decommissioning.

This involves safely sending all used Magnox fuel to Sellafield for reprocessing.

Once we have completed the defuelling process we begin preparing each site to enter a passive state. During this time the focus is on decommissioning and deplanting buildings and retrieving, treating and processing any waste.

Each site is then left in a passive state, allowing radiation levels to decay naturally over time. During this time the sites will be continuously monitored and planned maintenance and inspection activities will be undertaken.

Final site clearance is the last stage in a site’s lifecycle, which involves dismantling the reactor vessels and dispatching any remaining waste to its final destination. Once this work is complete sites can be released for a new use.
