INADVERTENT EMERGENCY SIREN ACTIVATION
"Calvert Cliffs control room was notified at 0110 EDT on 8/26/2012 by the Calvert Control Center (911) that sirens in the Calvert County area were activated. Reports were narrowed down to Lloyd Bowen Rd, Siren C15. At this time the siren is believed to be getting water in the controls due to inclement weather in the area. Maintenance Support is on their way to locally confirm and isolate the suspect siren.
"This event is reportable as a 4-hour Non-Emergency Notification 10CFR50.72(b)(2)(xi) as 'Any event resulting in notification to other government agencies that has been or will be made.'"
The licensee notified the NRC Resident Inspector.
See related EN #48233.

UNUSUAL EVENT DECLARED DUE TO EARTHQUAKE FELT ONSITE
A Notice of Unusual Event (NOUE) was declared at San Onofre due to an earthquake felt on site (EAL HU1.1). The US Geological Survey indicates that there was a 5.3 magnitude earthquake near Brawley California, about 125 miles southeast of the plant. There were no indication of any impact to site operations other than being felt by personnel. Equipment inspections and walkdowns are in progress.
The licensee has notified state and local authorities. The NRC Resident Inspector will be notified. Notified other FEDS (FEMA, DHS, DHS NICC and Nuclear SSA via email).
* * * UPDATE FROM BAYER TO HUFFMAN AT 1713 EDT ON 8/26/12 * * *
On August 26, 2012 at 1346 PDT, San Onofre exited the Unusual Event based on an earthquake felt on site. Shortly after exiting the UE, the licensee felt more shaking in the control room. The licensee confirmed with the US Geological Survey that there has been an aftershock. The aftershock was approximately the same magnitude (5.4) and location as the original earthquake (about 125 southeast of the site). The licensee declared another unusual event at 1403 PDT. The licensee will re-perform all equipment walkdowns and inspections.
The NRC Resident Inspector has been notified and is reporting to the site. R4DO (Hay), NRR EO (Lubinski), and IRD (Gott) notified.
* * * UPDATE AT 2352 EDT ON 8/26/2012 FROM ADAM BOW TO MARK ABRAMOVITZ * * *
"Exited the NOUE HU1.1 - Earthquake at 2017 PDT on 8/26/12."

INADVERTENT EMERGENCY SIREN ACTUATION
The Calvert Cliffs control room was notified at 1530 EDT on 8/26/2012 by a site employee that Siren C15 was intermittently alarming.

DISCOVERY OF AFTER-THE-FACT EMERGENCY CONDITION - UNUSUAL EVENT
"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"On August 26, 2012, at approximately 1231 Mountain Standard Time (MST), some Auxiliary Operators located in the Palo Verde Nuclear Generating Station (PVNGS) Operations Support Buildings reported to the control room that they had felt an earthquake. The US Geological Survey (USGS) internet web page recorded several small earthquakes in the Salton Sea area of Southern California. The earthquake was not felt by the control room staff and no Seismic Monitoring System alarms were received. The event was evaluated and a determination was made at that time that the event did not meet the classification criteria for declaration of an Unusual Event per the PVNGS Emergency Plan. Similarly, at 1358, personnel again reported they felt motion in the Operations Support Buildings and the USGS reported an aftershock in Southern California. The event was similarly determined to not meet the classification criteria for declaration of an Unusual Event.
"There were no indications of any impact to plant equipment or site operations other than being felt by personnel in the Operations Support Buildings.
"During post event reviews, it has been determined that these events met the classification criteria for declaration of an Unusual Event for a seismic event as specified by the PVNGS Emergency Plan. No emergency situation exists at this time.
"The NRC Resident Inspector was informed of this notification."
The licensee notified Maricopa County and the State of Arizona.
