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

2012
Dismantling of the primary circuit :
- Decontamination of the pressuriser and of the primary
loops
- Disposal of 2 SG to ANDRA in one piece
