SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a Quarterly inspection at Columbia Generating Station in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information. Findings being considered in the NRCs assessment are summarized in the table below.

List of Findings and Violations Failure to Enter the Operational Decision-Making Process for a Condition Reducing Operating Margin in Accordance with Station Procedures Cornerstone Significance Cross-cutting Report Aspect Section Initiating Events Green [H.14] - 71111.13 FIN 05000397/2019001-01 Conservative Closed Bias The inspectors identified a Green finding for the licensees failure to adhere to station procedure, Plant Procedures Manual 1.3.67, Operational Decision-Making Process,

Revision 17, Step 6.1, for a condition that creates an actual or potential reduction in operating or design margin. Specifically, the station failed to enter the Operational Decision-Making (ODM) process for degraded startup auxiliary power transformer oil level that reduced operating margin. This resulted in a lockout of the transformer requiring an unplanned entry into Technical Specification 3.8.1, AC Sources - Operating, Condition A for one offsite circuit inoperable and elevation of plant risk level to Orange Risk for emergent maintenance.

PLANT STATUS

The plant began the inspection period at 100 percent rated thermal power.

On January 12, 2019, the unit was down powered to 65 percent to perform a control rod sequence exchange. Reactor power returned to 100 percent on January 13, 2019.

On January 21, 2019, the unit was down powered to 65 percent due to condensate booster pump 2C discharge check valve COND-V-119C leakage. Reactor power returned to 100 percent on January 24, 2019, and remained at or near rated thermal power for the remainder of the inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

INSPECTION RESULTS

Failure to Enter the Operational Decision-Making Process for a Condition Reducing Operating Margin in Accordance with Station Procedures Cornerstone Significance Cross-cutting Report Aspect Section Initiating Events Green [H.14] - 71111.13 FIN 05000397/2019001-01 Conservative Closed Bias The inspectors identified a Green finding for the licensees failure to adhere to station procedure, Plant Procedures Manual 1.3.67, Operational Decision-Making Process, Revision 17, Step 6.1, for a condition that creates an actual or potential reduction in operating or design margin. Specifically, the station failed to enter the Operational Decision-Making (ODM) process for degraded startup auxiliary power transformer oil level that reduced operating margin. This resulted in a lockout of the transformer requiring an unplanned entry into Technical Specification 3.8.1, AC Sources - Operating, Condition A for one offsite circuit inoperable and elevation of plant risk level to Orange Risk for emergent maintenance.

Description:

At 4:07 a.m. on February 7, 2019, the plant entered abnormal procedures ABN-Transformer and ABN-Grid after the startup auxiliary power transformer, E-TR-S, locked out on low oil level. An operator in the field reported the oil level out-of-sight low with no observable oil leakage in the vicinity of the transformer.

The licensee determined a significant decrease in oil volume occurred as already sub-freezing outside temperatures dropped an additional 15°F that night. Because the pre-event level was already below the normal operating band, the level change due to temperature was sufficient to lockout the transformer on low oil level.

The inspectors review of the transformer yard logs found that E-TR-S oil level had been consistently recorded through the operating cycle as low in the indicating range, just above the alarm setpoint. Action Reports for alarms received during winter months in previous years indicate that the low temperatures of winter periodically caused the oil volume to shrink to the point of causing an oil level alarm. This phenomenon was a known issue and a nuisance to operators. Those Action Reports were either closed as being complete or closed to trending with no actionable assignments made. Work Requests related to oil addition to the transformer were deferred to the R24 Refueling Outage with the contingency to add oil online.

Plant Procedures Manual (PPM) 1.3.67, Operational Decision-Making (ODM) Process, provides a systematic method for making operational decisions that could significantly challenge plant safety, reduce operating margins, threaten generation, or pose risks to personnel or equipment. It is intended to be performed when there is an actual or potential reduction in operating or design margin. Maintaining the E-TR-S oil level low outside the normal operating band reduced the operating margin by increasing the transformers susceptibility to weather induced level fluctuations with the potential to cause a lockout. Yet, the licensee failed to enter the ODM process to address this reduction in operating margin during the several month period where the transformer oil level was consistently recorded as low. Operators should have entered the ODM process and corrected the low oil level condition to prevent the low temperatures from causing the level to shrink to the point that a transformer low oil level lockout occurred.

Corrective Action(s): The licensee coordinated with Bonneville Power Authority to add oil to E-TR-S. Additional corrective actions include assignments to revise the transformer yard logs to reflect the markings on the level instruments for both startup and backup transformers and to align the methods used by Engineering and Operations to more accurately record and track transformer oil levels.

Corrective Action Reference(s): Action Reports 389753, 389843, 374476, 387608, and 376707

Performance Assessment:

Performance Deficiency: The failure to adhere to station procedures was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it could reasonably be viewed as a precursor to a significant event. The inspectors determined the performance deficiency was more than minor because it adversely affected the Equipment Performance attribute of the Initiating Events cornerstone and its objective to limit the frequency of those events and operations that upset plant stability and challenge critical safety functions, during shutdown as well as power operations. Specifically, the failure to enter a chronic, degraded startup auxiliary power transformer oil level condition that reduced the plant operational margin into the ODM process for tracking and resolution resulted in an unexpected lockout of the transformer on low oil level caused by fluctuation in volume due to cold weather conditions. Loss of the startup auxiliary power transformer resulted in an abnormal electrical distribution and left the backup auxiliary power transformer as the only remaining offsite power source, therefore elevating plant risk level to Orange Risk.

Significance: The inspectors assessed the significance of the finding using Appendix A, Significance Determination of Reactor Inspection Findings for At - Power Situations. Using the questions in Exhibit 1, Initiating Events Screening Questions, the finding was determined to be of very low safety significance (Green) because

(1) the finding did not result in exceeding the reactor coolant system leak rate for a small loss-of-coolant-accident and

(2) did not affect other systems used to mitigate a loss-of-coolant-accident resulting in a total loss of their function.

Cross-cutting Aspect: H.14 - Conservative Bias: Individuals use decision-making-practices that emphasize prudent choices over those that are simply allowable. A proposed action is determined to be safe in order to proceed, rather than unsafe in order to stop. Rather, in this situation the licensee tolerated a degraded condition that reduced operating margin for operational convenience as opposed to identifying the issue as a challenge to plant reliability and entering it into the ODM process for higher visibility, tracking, and resolution.

Enforcement:

Inspectors did not identify a violation of regulatory requirements associated with this finding.
