UNUSUAL EVENT DECLARED DUE TO A MAIN TRANSFORMER FIRE LASTING FIRE LONGER THAN 10 MINUTES.

Main transformer fire caused a load rejection/automatic reactor scram. All rods fully inserted into the core. Offsite power is being supplied through their startup transformers. Offsite fire department, Vernon, responded with three fire trucks and one ambulance. Main transformer fire was extinguished at 0751 EDT. Their were no personnel injuries. All emergency core cooling systems and their emergency diesel generators are fully operable if needed. Reactor vessel water level is being maintained at its proper level via the condensate and feedwater system. Both recirculation pumps tripped. Licensee is looking into the reason why the recirculation pumps tripped. Their was no release of radioactivity from the plant. Licensee notified the states of New Hampshire, Vermont , Massachusetts and local surrounding counties of the declaration of an unusual event.

The NRC Resident Inspector was on scene when the event occurred.

* * * UPDATE FROM LAURIE TKACZYK TO JEFF ROTTON AT 1301 HRS. EDT ON 06/18/04 * * *

At 1245 hrs. EDT, the Licensee terminated the Unusual Event. The basis for the termination was that the fire is out, a reflash watch is established and the plant is stable. The hydrogen in the generator is depressurized and the plant is currently purging the generator with carbon dioxide.

The licensee has notified the NRC Resident Inspector. The Headquarters Operations Officer has notified R1DO (Dimitriadis), NRR EO (Reis), FEMA, DHS, DIRO (Wessman), HQPAO (Gagner), DIRO (Andrews), R1 (Blough and Wiggins).

The following information was obtained by the Licensee via facsimile:

"A TVA employee at Browns Ferry Nuclear Plant was transported by ambulance to Athens-Limestone hospital, where he was later pronounced dead after becoming ill at work on Friday, June 18, 2004. The employee was part of a team of engineers inspecting a motor control unit inside the Unit 3 Reactor Building when he complained of shortness of breath. Emergency medical personnel in Browns Ferry's Fire Operations organization were called to respond and transferred the employee to the Athens-Limestone hospital ambulance service, which took him to the hospital in Athens. The engineering team was taking photographs and thermal images of the motor control unit while it was in operation. The medical emergency was not related to the operation of Unit 3 reactor.

"This event is being reported pursuant to 10CFR 50.72(b)(2)(xi) as 'Any event or situation, related to the health and safety of the public or onsite personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an onsite fatality or inadvertent release of radioactively contaminated materials'."
