Work with us

We are responsible for the safe and secure clean-up of 12 nuclear sites and operation of one hydro-electric plant. Magnox Ltd works with the Nuclear Decommissioning Authority.

We manage our sites through their lifecycles, overseeing all aspects of operation, defuelling and decommissioning.

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

Once defuelling is complete, preparations begin to place sites in a passive state through decommissioning and deplanting buildings and retrieving, treating and processing waste.

Care and maintenance (C&M) is the name for this passive state. C&M enables radiation levels to decay naturally over time. The sites are monitored during C&M and planned maintenance and inspections take place. Final site clearance is the last lifecycle stage. The reactor vessels are dismantled and remaining waste is sent for disposal.

Our mission is to safely and securely deliver our 12 sites to closure with a workforce:

  • focused on achieving value for our customers and the taxpayer
  • motivated to deliver the site closure programmes
  • with clear future employment opportunities.
