Our phases of work

Each Magnox site goes through five phases in its lifecycle: generation, defuelling, care and maintenance (C&M) preparations, C&M and final site clearance.

Magnox manages sites in the following phases:

  • Generation – Magnox continues to generate electricity from the Maentwrog hydro-electric plant
  • Defuelling – Wylfa
  • C&M preparations – Berkeley, Bradwell, Chapelcross, Dungeness A, Harwell, Hinkley Point A, Hunterston A, Oldbury, Sizewell A, Trawsfynydd and Winfrith

Our phases of work

Generation

During generation Magnox will maximise electricity generation while ensuring continued excellent performance in nuclear safety and operations.

Defuelling

Reactors, cooling ponds and fuel cells containing used fuel are emptied, and the fuel is transferred off-site for reprocessing. Redundant plant can also be removed.

C&M Preparations

During this phase hazards are reduced, buildings are deplanted and demolished. Waste is managed and maintenance requirements minimised.

Final Site Clearance

This is the last stage in a site’s lifecycle with the removal of reactor vessels and building demolition. Sites will be declassified as nuclear licensed sites.
