LS1 EN-EL activities Power distribution and Operation


Replacement of SILCON UPSs

All cryo and machine : 82 UPS

Any new UPS connections Requests must be done before end of June 2012

12 Juin 2012

UPS machine : 2 UPS in RE (x16)2 UPS in UA (x8)2 UPS each LHC point (US, UW ou UJ) (x8)

UPS cryo :2 UPS on LHC even points (US, UW) (x4)2 UPS on surface even points (SA, SH) (x4)2 UPS in PM18


Replacement of SILCON UPSs

Impact on other activities: 6 weeks per area (for 2 UPS)

Distribution downstream off during works

Possible refeeding from diesel network (subject to request justified by safety)

Transport and handling: ~ 660 kg for an UPS and 2000 kg for battery sets (removal of old ones as well ) Lifts on Points 3, 5 et 7 too small for UPS : Width > 800 mm

Alcoves RE : A safety issue has to be considered: Charging batteries may lead to hydrogen production. Ventilation must be dimensioned so that the risk of explosion is eliminated (EN/EL, GS/ASE, HSE)

requirements/resources

The LS1 Project Leader decided


Cables & Fibres

Additional resources AGH (12 project associates from Krakow) Fellows & associates (+10 in 2011/2012) 2 installation contracts (doubled manpower) FSU being prepared Specialists + project managers required (skilled

and experienced people)

12 Juin 2012


Cables & Fibres

Help from other departments & experiments

We still want new people working with EL team in order to have coherent works done

Work supervisors Knowledge and experience of cable laying or fibre blowing technologies Experience in work site supervision Knowledge of site works

Project managers Project management People management Schedule & Budget management Knowledge of dedicated softwares(GESMAR, Câblothèque)

12 Juin 2012


Cables & Fibres

But there are limits to the increase of manpower:

Lack of experience Increase of manpower of contractors CERN access, hotels, logistics bottle neck, Base vie? Schedule/coactivity

12 Juin 2012


LS1 will be a very huge shutdown also for EN/EL

On the HV & LV infrastructure side, The program will be done with some additional resources

On the cables & fibres side, the situation is critical: prioritization is done but the effort is huge for the section in charge. Additional resources have been deployed from other departments: more are needed.

We are worried about the flow of requests which are still popping up in PLAN@CERN or elsewhere
