LHC ACCESS SYSTEM 11 Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: LHC Access Safety System Goals: Protect personnel during Beam operation -nobody inside - Stop LHC if a door is forced Allow Access operation when safety conditions are met -No radiation hazards (LHC beam, RF). Nuclear Safety system -Audited by the French Nuclear Authority INB Status: HW and SW Architecture prototyping done Identification of the interlocked LHC machine elements completed INB documentation completed Safety studies completed Contract for the realisation of the system started in October SW & HW Design progressing well

LHC ACCESS SYSTEM 12 Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: LHC Access Safety System – INB Architecture reviews with the French Nuclear Safety Authorities – IRSN: June, August, October Siemens safety PLCs accepted together with a diversified redundant system -cable loop surveying the external envelope of the machine and acting on the Beam Important Safety Elements -Cable loop design finished (budget – copper prices!) -Integration in the existing architecture First version of Annex 1 of Report Préliminaire de Sûreté, EDMS:

LHC ACCESS SYSTEM 13 Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: LHC Access Safety System – Remarks Involvement from AB to be continued: -Lack of official product manager -Fast answers to few remaining issues (patrol, radiation Veto etc.) -Integration of redundant cable loop -Operational procedures: Operator training Patrol procedures Equipment tests Lessons from the test -As we use Failsafe PLC: all must be perfectly mastered Otherwise it goes Failsafe Not easy in absence of specification

LHC ACCESS SYSTEM 24 Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: Planning Strategy

LHC ACCESS SYSTEM 25 Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: Installation Phase 1: No impact on magnet transport and installation in the tunnel To assure safety of personnel, as much as possible avoid the period of short circuit tests in UA / RA Access works will be in parallel with the activity of interconnection of magnet in the tunnel Phase 2: Access surface installation is only allowed to start in each point when HC in adjacent LSS sectors has started (to avoid perturbation of transport of heavy and big material) Phase 3: Co-activities not allowed during the first and last 2 weeks of Cold-down HC and the period dedicated to Powering test
