UNUSUAL EVENT DECLARED DUE TO AN AFTERSHOCK EARTHQUAKE
On August 25th at 0118 EDT, North Anna Power Station declared an Unusual Event due to seismic activity onsite (EAL HU 1.1). Both units are currently shutdown and electrical power is being supplied from offsite. There were no personnel injuries. There was no radiological release. Site structure and system inspections are in progress. No damage has been identified.
The NRC Resident Inspector and state and local authorities have been notified.
* * * UPDATE FROM JOHN BALTOR TO ERIC SIMPSON AT 1215 EDT ON 8/25/11 * * *
At 1149 EDT another minor tremor was felt at the station. No geological information is available at this time. There is no immediate indication of any equipment damage. Walkdowns are being performed at this time.
North Anna Emergency Management indicated that there was currently no plan to secure from the Notification of Unusual Event until there is sufficient indication that the station will not experience any additional aftershocks to prevent having to re-enter an emergency status once exited.
The current status of North Anna, Unit 1 is Mode 5. Unit 2 is in Mode 3 in preparation for cool down.
The licensee will verify that the NRC Resident Inspector is notified.
Notified IRD (Marshall), NRR (Thorp), and R2DO (Widmann).
