| Title | Loss of Communications with Virginia State Eoc Due to Power Outage |
| Event Description | 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. |
