AUTOSTART OF "B" EDG DUE TO LOSS OF OFFSITE POWER CIRCUIT 767
"At approximately 0239 hours on June 3, 2012 the 'B' Emergency Diesel Generator (EDG) automatically started when offsite power circuit 767 was de-energized. The EDG started and re-energized Safe Guards busses 16 and 17. The selected Service Water (SW) pump 'B' automatically started to supply cooling to the EDG.
"The operators responded to the loss of circuit 767 using abnormal operating procedure AP-ELEC.1 'Loss of 12A and/or 12B Busses'.
"Offsite power was restored to 12B bus using ER-ELEC.1 'Restoration of Offsite Power' on circuit 7T at 0318 hours. The 'B' EDG was shutdown at 0445 hours.
"The initial investigation of the loss of circuit 767 indicates that the likely cause was due to wildlife, e.g., raccoon."
The licensee informed the NRC Resident Inspector.

DISCOVERY OF AFTER-THE-FACT EMERGENCY CONDITION (UNUSUAL EVENT)
"At 1930 [EST] on November 28, 2012, it was determined that a Notification of Unusual Event (NOUE) was not declared for an event that occurred on June 3, 2012, when an equipment failure resulted in a deposit of ion exchange resin onto the floor of the Radioactive Waste building. Subsequent radiological surveys indicated that conditions met the requirements for a NOUE in accordance with the Perry Nuclear Power Plant Emergency Plan.
"This report is being provided within one hour of the recognition of the undeclared event. As discussed in NUREG 1022, Revision 2, an actual declaration of an Unusual Event is not necessary. The Initiating Conditions for the emergency classification no longer existed at the time of recognition.
"The NRC Resident Inspector has been notified."
