There was no visible flame at this time. In response, the 'A' condensate pump was started. Due to a suspected malfunction of the 'A' condensate pump discharge valve, a low water level condition developed in the deaerator storage tank. The order was then given to manually trip the reactor. However, before the operator could complete this action, the low level condition automatically tripped the feedwater pumps and the main turbine which by design tripped the reactor at 1133.</br>A Notification of Unusual Event (NUE) was declared at 1141 due to a fire in the protected area lasting for more than 15 minutes. The fire was initially extinguished at 1200. Subsequently, a small flame was noted within the pump motor housing upon removal of an inspection cover at 1253. The fire was ultimately extinguished at 1317.</br>The plant is currently stable in mode 3. According to current indications, all safety systems operated as required. The fire was fully contained within the pump motor housing and did not cause any collateral damage. No radioactivity was released to the environment and there were no injuries.</br>The licensee requested offsite assistance from the Fairfield Fire Department.</br>All control rods fully inserted from the automatic trip. Decay heat was being removed via emergency feedwater into the steam generators through the steam dumps into the main condenser. Normal offsite power was available and electrical power was in normal alignment. </br>The licensee notified the NRC Resident Inspector. The licensee notified state and local government agencies.</br> * * * UPDATE ON 8/25/05 AT 1346 EDT FROM R. SWEET TO SNYDER * * * </br>At 1327 the licensee terminated the Unusual Event.
