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.
