UNUSUAL EVENT (EAL #16 - Fire) declared at 0327 on 6/27/05 due to uncontrolled fire in the Unit 4 Main Transformer lasting longer than 10 minutes. Unit 4 experienced an automatic reactor trip from 100% on a turbine trip due to a fire in the Main Transformer. The fire was extinguished after approximately 25 minutes. On-site fire brigade and Miami-Dade fire department responded. The cause of the fire is under investigation.
The reactor is stable in Mode 3. No safety systems were affected. All rods fully inserted, no ECCS actuations, no relief valves lifted and no personnel injuries occurred. Offsite power is still available and no emergency diesels auto started, however, there was an auxiliary feedwater actuation.
Hazardous Material response is being implemented due to discharge of transformer oil. There may be a possible press release on this event.
The NRC Resident Inspector was notified along with State and local agencies.

The NOUE was terminated at 05:00 due to the fire being extinguished and the emergency no longer existing.
The NRC Resident Inspector was notified.

"At 1150 on June 27, 2005 Quad Cities Station was notified that the calculated post-LOCA switchyard voltage is below the minimum acceptable value required to ensure offsite power will remain available following a design basis accident. The appropriate Technical Specification Actions have been taken for both Units. The ability of the Emergency Diesel Generators to fulfill their design function is not affected by this condition. This event is being reported in accordance with 10CFR50.72(b)(3)(v)(D) as a condition that could have prevented the fulfillment of a safety function given the predicted post-LOCA switchyard voltage.
"Actual Switchyard voltage at the time of this notification is 356 kV. The required minimum post-accident switchyard voltage for current conditions is 352.9 kV for Unit-1 and 351 kV for Unit-2, while the projected post-accident voltage which prompted this notification is 349.8 kV. At 1320 hrs on June 27, the projected post-accident voltage was 351.3kV. This prediction satisfies the minimum Unit 2 voltage requirement, but is still below the minimum voltage for Unit 1.
"This notification is similar to the condition reported on April 29, 2005 (EN #41652) and June 11, 2005 (EN #41766)."
