PLANT STATUS

Unit 3 began the inspection period at rated thermal power. On May 18, 2019, operators manually tripped the unit in response to lowering steam generator feedwater levels. The cause of the event was an electrical grid disturbance that resulted in turbine control valve position deviation faults. All four turbine control valves drifted closed by design in response to the position deviation faults. Unit 3 was returned to rated thermal power on May 20, 2019. On May 22, 2019, Unit 3 was down powered to 82 percent for 3C condensate pump maintenance. The unit was returned to rated thermal power on May 23, 2019, and remained at or near rated thermal power for the remainder of the inspection period.

Unit 4 began the inspection period in a refueling outage. The unit was returned to rated thermal power on April 11. 2019, and operated at or near rated thermal power for the remainder of the inspection period.

INSPECTION SCOPES

On April 4, 2018, the inspectors inquired about FPLs determination that the 3A EDG was operable during a fuel oil (fuel) transfer to the 4B EDG fuel oil storage tank (FOST).

To perform the fuel transfer, operators aligned the 3A EDG fuel transfer system by: 1)removing the 3A EDG fuel transfer pump control switch from the automatic position; 2)closing the air-operated fill valve CV-3-2046A, to the 3A EDG day tank, by isolating and venting its instrument air supply line; and, 3) opening normally locked-closed Unit 3 and Unit 4 fuel transfer valves. FPL did not consider the 3A EDG inoperable in this alignment and credited operator manual actions (OMAs) to restore its day tank to automatic fill operation.

FPL entered this issue into its corrective action program as AR 2269269 to complete a design and license basis evaluation of EDG operability during cross unit fuel oil transfers. This issue was described as URI 05000250, 251/2018002-01, Unit 3 EDG Operability during Fuel Oil Transfer to Unit 4 FOSTs in NRC Inspection Report 05000250/2018002 and 05000251/2018002 (ADAMS ML18222A375).

FPL completed the design and license basis evaluation and concluded that an EDG is not operable when its fuel transfer system line-up is not in automatic operation. Specifically, any time the EDG fuel transfer system requires OMAs to perform its function, the associated EDG will be considered inoperable. Using the revised EDG operability interpretation, FPL completed a three-year review to determine if there were any EDG Technical Specification (TS) compliance issues during cross unit fuel oil transfers. There were five fuel transfers completed in 2019: two on February 28; one on April 17; and two on May 1. These fuel transfers did include logging and declaring the diesel out of service as required by the licensees interim corrective actions and shows the fuel transfers took on average about 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> each. Through review of these control room logs, fuel transfer procedures, and operational history of EDG fuel oil transfers, FPL concluded that the fuel transfers were generally and reasonably completed within one to two hours at most. However, FPL determined that over the three-year period prior to 2019, there were multiple examples where a Unit 3 EDG should have been considered inoperable for a cross unit or cross train fuel transfer and TS action statements would have applied. The action statements were administrative in nature and included:

  • 3.8.1.1.b. to demonstrate the operability of the required startup transformers and their associated circuits by performing Surveillance Requirement 4.8.1.1.1.a within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> thereafter;
  • 3.8.1.1.d.1 within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to verify that all required systems, subsystems, trains, components, and devices (except safety injection pumps) that depend on the remaining required operable diesel generators as a source of emergency power are also operable; and,
  • 3.8.1.1.d.2. within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to verify that at least two safety injection pumps are operable and capable of being powered from their associated operable diesel generators.

Procedure 0-OSP-023.3, Equipment Operability Verification with an Emergency Diesel Generator Inoperable, implements these surveillance requirements. FPLs review identified that eight Unit 3 to Unit 4 fuel oil transfers occurred during a Unit 4 EDG out of service period.

The dates of these fuel transfers were: August 17, 2016; August 30, 2016; January 16, 2018; April 4, 2018; April 5, 2018; two on April 24, 2018; and May 22, 2018. Using the revised EDG operability criteria, this now resulted in an inoperable EDG on each unit and the most limiting TS action statement, 3.8.1.1.d. would have applied and required each unit to be in hot standby within the next six hours. However, the inspectors agreed this action statement was never required because the cross unit or cross train fuel oil transfers historically were reasonably completed in one to two hours.

This URI is closed to a Minor Violation: Unit 3 Emergency Diesel Generator Operability during Fuel Oil Transfer to Unit 4 Fuel Oil Storage Tanks (URI 05000250, 251/2018-002-01)

Minor Violation: Unit 3 Emergency Diesel Generator Operability during Fuel Oil 71111.15 Transfer to Unit 4 Fuel Oil Storage Tanks (URI 05000250, 251/2018-002-01)

The inspectors reviewed FPLs operability assessment documented in AR 2290093 and the EDG fuel transfer procedures to verify no other safety-related structures, systems, or components were made inoperable during the fuel transfer process. The inspectors reviewed the timeline for selected examples of EDG inoperability during fuel transfer operations and confirmed the startup transformers and the safety injection pumps were operable during the periods of EDG inoperability. The inspectors reviewed the EDG start and sequencer circuitry and confirmed the EDG was available to start and sequence during fuel transfer operations. The inspectors reviewed calculation PTN-0FSM-19-001 and AR 228977228977that determined the required TS minimum 2000 gallons of fuel in the combined day tank and skid tank with a fuel consumption rate of 132 gallons per hour, equates to approximately 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> of EDG operation. This provided the fuel capacity for the EDG to operate and supply vital power for 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> during a loss of offsite power (LOOP) scenario. Additionally, for a maximum load a single diesel could experience during a station black out event, the consumption rate would be 220 gallons per hour and would equate to 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> of EDG operation. Hence, EDG fuel transfer system could be realigned to operable status and function automatically well before fuel transfer to the day tank is required.

The inspectors determined the failure to consider an EDG inoperable during a cross unit or cross train fuel transfer that disabled the automatic fuel transfer operation from the FOST to the associated EDG day tank was a performance deficiency that resulted in several failures to complete TS action statements 3.8.1.1.b, 3.8.1.1.d.1, and 3.8.1.1.d.2.

Screening: TS action statements 3.8.1.1.b, 3.8.1.1.d.1, and 3.8.1.1.d.2. were administrative in nature and the results of the required surveillances would have been satisfied. There was no safety significance to this performance deficiency and this issue is treated as a minor violation. Additionally, this issue is similar to the minor issue described in NRC Inspection Manual Chapter 0612 Appendix E, example 4.I, Procedural Errors in that the failure to implement a TS and procedural requirement had no safety impact was considered a minor issue.

Enforcement:

This failure to comply with Technical Specifications 3.8.1.1.b, 3.8.1.1.d.1, and 3.8.1.1.d.2 constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy. FPL now declares the EDG inoperable during fuel transfers when the associated fuel transfer system is not aligned for automatic operation and complies with the required TS actions statements during these fuel transfers.
