| Title | Planned Power Outage at Primary Emergency Operations Facility (Eof) |
| Event Description | Southern California Edison has planned work scheduled for the San Onofre Emergency Operations Facility (EOF), for Sunday, February 21, 2010. The work is being done in order to replace a faulty circuit breaker and will result in area lighting being out in the building from approximately 0800 through 1600. During the time that the lighting is out, the EOF will be considered non-functional. Should conditions occur that would merit activation, EOF responders would be directed to the alternate EOF located in Irvine, CA.
This planned EOF outage is being reported in accordance with 10 CFR 50.72(b)(3)(xiii). The licensee has notified the NRC Resident Inspector.
Follow up phone call to one made on 2/19/10 regarding planned power outage at normal EOF. Commenced 1145 [PST] today (2/21); restored 1715 [PST]. The licensee will notify the NRC Resident Inspector. Notified R4DO (Miller) |
