AFTER THE FACT DISCOVERY OF AN UNUSUAL EVENT ENTRY CONDITION
"During an extent of condition review of past radiological events, it was identified that an event on November 17, 2010 met the E-Plan entry criteria for GU1, 'Unexpected Increase In Plant Radiation Levels'. Due to an equipment deficiency, dose rates in one section of the Radwaste building rose from 0.08 mrem/hr to 80 mrem/hr. This satisfied the E-Plan criteria of a 1000 times change over normal radiation levels. This was initially identified in [Perry] Condition Report 2010-85937."
The licensee notified the NRC Resident Inspector and will notify State and local authorities.
