The critical path for the project concerns the activities in the HR cavern :

• Primary circuit dismantling

• Renewal of the water filling circuit of the pool

• Vessel dismantling

2011

Dismantling of the primary circuit : 3 SG decontaminated and the 4th

SG extracted

End of nuclear auxiliaries dismantling in HK cavern, except

the casemates

2011

Dismantling of the primary circuit : 3 SG decontaminated and the 4th

2012

Dismantling of the primary circuit :

- Decontamination of the pressuriser and of the primary

loops

- Disposal of 2 SG to ANDRA in one piece
