Description
EN/EL will be leading 3 main LHC projects:
- R2E (relocation of EL equipment in LHC points 1, 5, 7 and 8)
- Water cooled cables to be replaced in 3 LHC points
- UPS (APC SILCON) to be replaced (circa 80 units)
EN/EL will be involved in many others. Only a few of them are known today. (Vacuum pump cabling, RF cables replacement, QPS cabling …..)
Several non LHC projects but directly connected to LHC runs will required a major contribution from EN/EL. Computer center, B513 upgrade and CCC upgrade will be the main ones.
Several EL Consolidation works on the power distribution network are more or less affecting LHC operations:
- Prevessin distribution substation & 3.3kV safety network
- Upgrade/consolidation of 66kV substation protection system
- Upgrade of SW (ME59) substation (including 66/18kV trafo)
- 400kV maintenance on both CERN & RTE sides
And many other tasks, not connected to LHC operations, will sharply increase the EL turnover for the shutdown..
Postponing the long shutdown from 2012 to 2013 will mainly:
- increase the risk on SPS irradiated cables (no replacement since 2008/2009 campaign)
- Induce schedule changes on CC, B513 upgrade project
- Postpone for the 3rd time RTE maintenance on Bois-Tollot substation and Genissiat power line
