Example of Failure

LIU-SPS 22/07/2015

• Blast in EMD5/B3 on 22/09/2013 (during LS1);

• The switchgear had to be replaced (>6 months);

• During a run, such a failure would stop the SPS for several

weeks in the best case (with a temporary solution).

Risks - Interaction with non-EL Users

Electrical Network Consolidation Project

Non-EL Users

Some works planned by non-EL users will require the availability of some parts of the networks concerned by the EL consolidation

Some new needs will have to be taken into account by an “upgrade” part of the project

Collection of User Requirement - Parameters

• List of electrical loads, location;

• Rated power;

• Absorbed power;

• Power factor;

• Nominal voltage;

• Load profile;

• Load criticality;

• Space required;

• Planning of installation and commissioning.LIU-SPS 22/07/2015

Conclusion

• A wide project for EN/EL, able to ensure the reliability of the SPS electrical supply for the next 30 years;

• Good opportunity to coordinate upgrade and consolidation works in a single project;

• The Study Phase requires the collection of user needs for upgrade (for end of October 2015);

• General strategy for all SPS site to be determined by the end of the year.
