• 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
