Title | Fermi Declares Alert Due to a Fire in an Emergency Diesel Generator Turbo Charger Lagging |
Event Description | At 1405 EDT on 3/20/14, Fermi Nuclear Station declared an Alert due to a fire in the lagging of an Emergency Diesel Generator Turbo Charger. 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.
At 1359 [EDT on 3/20/14], with the plant in Mode 4, a fire was confirmed on Emergency Diesel Generator (EDG)-11 turbocharger. At 1402, the fire was extinguished with a CO2 extinguisher. An ALERT was declared at 1405 and Assembly and Accountability was ordered by the Emergency Director. The Assembly and Accountability was completed satisfactorily by 1441. The fire was from oil soaked lagging on the engine turbocharger. The insulation was removed and the engine exhaust header was inspected. The damage was limited to only the lagging. The room has been ventilated using the Engine room fans and has been cleared of all of the smoke. The Emergency Director terminated the event at 1532 [EDT on 3/20/14]. The Resident Inspector has been notified. Notified R3RA (Pederson), NRR (Dorman), R3DO (Lara), IRD (Grant), IRD (Morris), DHS SWO, DOE, FEMA, HHS, NICC, USDA, EPA, FDA, and Canadian Nuclear Safety Commission (Tennant). Notified NuclearSSA via email only. |
