Event Text
UNUSUAL EVENT DECLARED PER EAL 14.1- FIRE LASTING GREATER THAN 15 MINUTES & ACTIVATION OF THE FIRE BRIGADE.

"At 0230 on 10/3/02, the control room was notified that there was a fire at Startup Transformer T-20. Unit 2 was in the process of starting up and was at a pressure of 435 psig and range 8 on the IRMs. T-20 lost power which caused the recirc pumps on Unit 2 to trip. With no recirculation, operators placed the mode switch to shutdown. All rods were inserted. Unit 1 was at 100% power at the time and continued to operate. The Station Fire Brigade was activated. The deluge system extinguished the fire in 10 minutes"

Non-Vital power is being supplied to T-20 Startup Transformer Bus from Startup Transformer T-10 via cross tie breaker. Offsite fire department was called but was not needed. All Emergency Core Cooling systems and the Emergency Diesel Generators are fully operable if needed.

The Unusual event will be terminated after an assessment of what caused the Startup Transformer T-20 fire/failure.


The licensee notified the State of PA, surrounding counties and the NRC Resident Inspector of the declaration of an Unusual Event.

MANUAL REACTOR SCRAM DUE TO LOSS OF POWER TO RECIRC PUMPS.

"At 0230 on 01/3/02, the control room was notified that there was a fire at Startup Transformer T-20. Unit 2 was in the process of starting up and was at a pressure of 435 psig and range 8 on the IRMs. T-20 lost power which caused the recirc pumps on Unit 2 to trip. With no recalculation while in Mode 2, Tech Specs requires the unit to be in Mode 3 within 12 hours. Operations placed the mode switch to shutdown. All rods were inserted. Unit 1 was at 100% power at the time and continued to operate. The Station Fire Brigade was activated. The deluge system extinguished the fire in 10 minutes. An Unusual Event was declared under EAL 14.1 at 03:15.

"This is a 4 hr Non-Emergency notification under 10 CFR 50.72(b)(2)(I) for a Tech Spec required shutdown and a 4 hr Non-Emergency notification under 10 CFR 50.72(b)(2)(iv)(B) for an RPS actuation."

A press release will be made.

The NRC Resident Inspector was notified of this event by the licensee.

POTENTIAL UNABLE TO SAFE SHUTDOWN DUE TO CORE FLOW INDICATION OUT OF TOLERANCE

"During performance of procedure PNPS 9.17 Core Flow Evaluation a discrepancy in the 'A' Loop core flow between EPIC and RPS indication was noted. This caused Pilgrim to investigate and perform a calibration of the 'A' RPS Flow converter. The initial 'as found' set points were out of tolerance per the procedure. Adjustments were attempted but we were unable to calibrate the flow converter. The 'A' Flow Converter was declared inop and a half-scram signal was maintained on the 'A' RPS channel. Pilgrim is continuing its efforts to replace and/or repair the 'A' Flow converter. It is unknown at this time if the as found flow indications were acceptable to fulfill its safety function."

The Licensee has notified the NRC Resident Inspector.
