Magnox
• One generating nuclear site• Three defuelling nuclear sites• Six decommissioning nuclear sites• One hydro-electric plant
• Owned by EnergySolutions• Working for the sites’ owner, the
Nuclear Decommissioning Authority

• Maximise the value from the remaining operating site at Wylfa (and Oldbury until it ceased generation in February 2012)
• Complete the Magnox Operating Programme (MOP) - dealing with the remaining spent fuel
• Deliver early care and maintenance at Bradwell and Trawsfynydd
• Deliver a safe interim care and maintenance state at Chapelcross and Dungeness
• Pioneer innovative and transformational ways of working through the introduction of Strategic Programme delivery with a view to minimising lifetime costs
• Safe implementation of the Berkeley active waste vaults retrieval project to address one of the highest hazards
• Reshape and reduce our workforce in line with the MODP whilst providing strong and responsive support to our people

Fuelled sites
• Oldbury – generated £300 million extra
revenue from 2008 – 2012 through inter-
reactor transfer and extended generation
• Wylfa – secured extended generation
• Dungeness A – defuelling completed
• Chapelcross - cooling pond one drained
• Sizewell A – major asbestos stripping
project completed
Decommissioning sites
• Berkeley – The reactors were the first in the UK to enter safestore, while the first Intermediate Level Waste (ILW) recovered from the vaults and placed into fit-for-purpose interim storage• Hinkley Point A – turbine hall backfilled in conjunction with EDF Energy
• Hunterston A – ILW store sealed and ready to be commissioned
Accelerated sites
• Bradwell – • the turbine hall has been demolished
• a fuel element debris dissolution plant
is being built
• the pond has been drained and painted
• work has begun to construct an interim
storage facility for ILW.
• Trawsfynydd –
• the reactors are being prepared for
safestore
• ILW is being placed into interim storage
• the ponds are being scabbled

MODP care and maintenance dates
MODP outcomes
• Waste is dealt with earlier than originally planned and hazard is reduced
• Lead and learn means that experience is shared between the sites improving delivery as each programme develops
MODP outcomes
• Care and maintenance is broughtforward – savings 34 site years fromthe total required to get all the sites to that phase
• Adding all the benefits togetherleads to a lifetime saving of£1.3 billion
