Require a plan b in case pipes are damaged during construction of RILIS

EDMS 3340506

• Carottages to be done to cover the scenario if old pipes are damaged and we need to put in new pipes and re-route:
  • Either 2x100mm or 1x200mm holes required from R-024 to R-028
  • From R-024 to b.838, 1x100mm hole
• To be checked with RP, if there is a way they would accept to condemn the old pipes remaining in the chamber and being sealed off with epoxy
• Validation required from RP on plugs for the new holes
