The Alert notification was based on EAL HA02, fire or explosion affecting the operability of plant safety systems required to establish or maintain safe shutdown. The fire in the EDG-11 turbocharger lagging occurred during testing. The fire was extinguished using handheld CO2 fire extinguishers and a reflash watch was set. EDG-11 has been removed from service and damage is minimal. The plant is shutdown in Mode 4 for Refueling Outage 16. All parameters associated with the reactor are stable. RHR Pump D remains in service in Shutdown Cooling and is unaffected by the EDG-11 fire. There has been no other impact on the plant electrical systems or shutdown cooling and Fermi Nuclear Station remains in an Alert pending further evaluation. The NRC remained in Normal Mode. The licensee has informed the NRC Resident Inspector. Notified DHS SWO, DOE, FEMA, HHS, NICC, USDA, EPA, and FDA. Notified NuclearSSA via email only. * * * UPDATE FROM SAM HASSOUN TO JOHN SHOEMAKER AT 1535 EDT ON 3/20/13 * * * At 1359 [EDT on 3/20/14], with the plant in Mode 4, a fire was confirmed on Emergency Diesel Generator (EDG)-11 turbocharger.
