| Title | Loss of Communications with Virginia State Eoc Due to Power Outage |
| Event Description | At 0828 EST on 12/23/2013, the Surry Power Station 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 ringdown 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 and all communications were supplied by an Uninterruptable Power Supply (UPS). Subsequently, the UPS batteries depleted and all communications were lost. At that time, (0828 EST) the Virginia State EOC personnel notified the Surry control room and supplied individual cellular phone numbers as an alternative method of contacting the Virginia State EOC.
This event 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. |
