| Title | Unusual Event Declared Due to Loss of Offsite Notification Capabilities |
| Event Description | At 1230 hrs. EST, the licensee discovered that offsite notification capabilities were lost. Upon discovery, they declared a Notification Of Unusual Event (NOUE) under EAL 7.3.2.
At the time of discovery, the licensee was in their adverse weather procedure due to winds exceeding 55 mph on site. The high winds caused a loss of electrical power to non-vital power block facilities, including the site PBX (Private Branch Exchange). The backup diesel generator for PBX power initially failed to start but was manually started at 1300 hrs. and PBX functions were restored. No other vital equipment was adversely affected by the loss of non-vital power. The licensee will remain in the NOUE until normal power is restored to the power block. The licensee has notified the NRC Resident Inspector.
The licensee terminated the Unusual Event at 2015 EST on 1/30/08 based on restoration of normal offsite power to the PBX. In addition, the backup diesel power supply to the PBX has been verified to be functional and available. The licensee has also stationed a spare backup diesel if needed. All phone lines have been tested and confirmed to be back in service with the exception to the RECS line (dedicated line to State and County Officials). Backup commercial lines to the State and County Officials are available. The licensee will be notifying the NRC Resident Inspector. R1DO (Perry), FEMA and DHS notified. |
