LOSS OF COMMUNICATIONS WITH VIRGINIA STATE EOC DUE TO POWER OUTAGE

"At 0828 EST on 12/23/2013, the North Anna control room was notified that the Virginia State Emergency Operations Center (EOC) had lost all power and all offsite communications. This included commercial phone lines, automatic ring downs, and the State ring down loop (lnsta-phone). At 0900 EST, all communications were restored once emergency generators were placed in service at Virginia State EOC. The Virginia State EOC initially lost offsite power only but all communications were supplied power by an Uninterruptable Power Supply (UPS). Subsequently, the UPS batteries depleted and all communications were lost. At that time (0828 EST) Virginia State EOC personnel notified the North Anna control room and supplied individual cellular phone numbers as an alternative method of contacting the Virginia State EOC.

"This report is reportable in accordance with 10CFR50.72(b)(3)(xiii), any event that results in a major loss of offsite communications capability, (e.g. Emergency Notification System)."

The licensee has notified the NRC Resident Inspector and Louisa County.

HISTORICAL GAPS IN HIGH ENERGY LINE BREAK BARRIER

"At 1930 EST on June 7, 2012, it was determined that a series of gaps in a high energy line break (HELB) barrier rendered equipment in the west 480 VAC switchgear room inoperable. There is evidence that this condition had existed since initial construction. The openings were sealed and the equipment restored to operable status at 1605 EST on June 8, 2012. This condition was previously reported to the NRC pursuant to 10 CFR 50.73(a)(2)(i)(B) in LER 2012-001-00. Upon further engineering analysis, it was determined that for limited exposure times safety functions could have been prevented for certain postulated high energy line breaks. Therefore, this condition is also being reported pursuant to 10 CFR 50.73(a)(2)(v)(A),(D), and 10 CFR 50.72(b)(3)(v). The NRC Senior Resident Inspector has been notified."
