Planning S176 General Current situation SercAL planning v0.9 based on maintenance windows planning v7 One week extension will be used by S176 to: Anticipate 1.8K maintenance to provide more compact intervention compared to initial planning Anticipate shipment for MR major overhauling and extend MR and/or SR maintenance windows Plan tasks to avoid critical path beginning of 2018, in coordination with OP. All LHC 4.5K must be available during CERN closure. Planning detailed review with SercAL Planned 07/11/2017 Coordination planning with other sections To Be Planned mid November

Soupapes 100% Proposition de traitement à hauteur de 34% 45%, afin de trouver le meilleur compromis entre le respect de la réglementation tout en minimisant les ouvertures de circuits. Décision en séance de ne pas traiter les soupapes d’eau P18 et P2 car sur chemins critiques  Demandes de dérogation.

Thermographie Campagnes de thermographie, à valider Dernière semaine de RUN pour les installations mises à l’arrêt dès le début du YETS (1.8K, Première semaine du YETS pours les autres
