EN/EL Activities during the next long Shutdown

The EL group will participate in many activities during the next long shutdown. They are divided in four categories: • Projects which require an extension or modification of the distribution network. • Consolidation work of the electrical distribution infrastructure led by EN/EL. • Scheduled maintenance activities and, in addition, the maintenance activities postponed since the start of the LHC. • Many upgrades of EN/EL infrastructure following an evolution of the power request (from EN/EL or other groups). It should be noticed that so far, we know only a small part of the work for which we will be involved. Indeed, projects must be sufficiently defined by our colleagues before submitting us their request. Furthermore, it should be noted that the decision to delay from 2012 to 2013 the long shutdown will lead to a schedule change of some projects and will increase the risk of failure of EN/EL equipment due to a lack of maintenance. This postponement of the long shutdown will be preceded by an additional Christmas break; we hope it will be longer than the past two. The work program is too tight and leaves us no time to repair any defects found during the various tests and increases our rate of human mistakes.
