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.
