6 Separation from TI2 tunnel (ODH risk)
PPG_TI2 at BA7 reinforced to sustain a pressure up to 35mbar plus some sealing around cables and beam pipe
Started from scratch

7 Handling means (PR632 crane repair, BA7 door)
• First inspection in January 09.• Not operated for more than 10
years.• A lot of components to be changed
(3 speed variators, remote control, 3 motors….)
• As expected repair cost > 100 k, price enquiry needed delays.
• Cost & delay saving approach : dismount the crane for repair at the surface (EHN1)
• Goal : back and operational underground in early 2010
• EN-HE will start dismounting it end of next week after cleaning-up by ASN under
RP team monitoring. 13 subsets identified.• BA7 motorized door to be refurbished by the end of the year.

• Will help a lot regarding ALARA principles
• Can be carried out within one week before Xmas shutdown
• Detailed discussion tomorrow with survey responsible.
