SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at South Texas Project Electric Generating Station, Units 1 and 2, 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.
List of Findings and Violations
Failure to Provide Oversight Leads to Multiple Examples of Switchyard Insulator Flashovers Cornerstone Significance Cross-Cutting Aspect Report Section Initiating Events Green FIN 05000498,05000499/2022003-01 Open/Closed None (NPP)71152A A self-revealed Green finding was identified for the licensees failure to adequately implement requirements of procedure 0PGP03-XS-0001, Switchyard Management, revision 11, to ensure adequate oversight of switchyard component maintenance. Specifically, the licensee failed to ensure that coatings of switchyard insulators were maintained. This condition resulted in flashovers which caused a de-energization of the switchyard south electrical bus and starting of safety-related equipment.

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. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

INSPECTION RESULTS
Failure to Provide Oversight Leads to Multiple Examples of Switchyard Insulator Flashovers Cornerstone Significance Cross-Cutting Aspect Report Section Initiating Events Green FIN 05000498,05000499/2022003-01 Open/Closed None (NPP)71152A A self-revealed Green finding was identified for the licensees failure to adequately implement requirements of procedure 0PGP03-XS-0001, Switchyard Management, revision 11, to ensure adequate oversight of switchyard component maintenance. Specifically, the licensee failed to ensure that coatings of switchyard insulators were maintained. This condition resulted in flashovers which caused a de-energization of the switchyard south electrical bus and starting of safety-related equipment.
Description:
On January 6, 2022, the licensee experienced a de-energization of the switchyard south electrical bus due to leakage current discharging to ground, otherwise known as a flashover. The unexpected de-energization resulted in a loss of power to the Unit 2 train B engineered safety features (ESF) 4160V bus. This caused an automatic start of the Unit 2 train B emergency diesel generator due to the undervoltage condition on the ESF bus.
The licensee found the south bus had de-energized due to an electrical flashover event as a result of an insulator on the south bus. The event was reported in licensee event report 2022-001 on March 4, 2022.
On April 13, 2022, the licensee again experienced a de-energization of the switchyard south electrical bus due to a flashover. No automatic actuation of any emergency diesel generator occurred because the Unit 2 train B ESF 4160V bus was temporarily aligned to the Unit 1 standby transformer to support maintenance. The cause was determined to be two different insulators but of the same two-piece design as the first occurrence.
The insulators in the licensees electrical switchyard are owned and maintained by the transmission distribution service provider. This entity had the insulator from the first flashover event analyzed. A report was provided to the licensee that concluded the insulator had areas where the room-temperature-vulcanizing silicone rubber coating was degraded and that large sections of the insulator had lost its hydrophobicity, or its ability to repel moisture, and instead became hydrophilic, having an affinity to spread water across its surface to maximize water coverage. A combination of contamination of the surface of the insulator combined with wetting of a hydrophilic insulator surface was reported as the likely cause the flashover.
The licensee performed a cause evaluation which stated that the equipment that failed was a transmission distribution service provider owned piece of equipment and that the service provider also performed all maintenance. When the inspectors questioned when the last time the insulator had been recoated or replaced, the licensee stated that they did not have a record for the last time either activity had been performed and neither did the transmission distribution service provider.
The inspectors researched licensee switchyard procedures and found statements in 0PGP03-XS-0001, Switchyard Management, revision 11, which indicate that the licensee is responsible for performing switchyard PM [preventive maintenance] oversight. The inspectors determined that the licensee failed to provide adequate oversight over preventive maintenance of switchyard components as evidenced by the lack of records for previous insulator maintenance and lack of scheduled future maintenance activities.
Corrective Actions: The licensee ensured that the transmission distribution service provider replaced all switchyard insulators of similar build as the ones which caused the flashovers.
The licensee then washed and commenced recoating the remaining insulators in the switchyard. The licensee also began working with the transmission distribution service provider to establish a preventive maintenance schedule for tracking insulator coatings and a monitoring program to gauge when environmental conditions warrant washing the insulators.
Corrective Action References: condition reports (CR) 2022-235, CR 2022-3717, and CR 2022-9617
Performance Assessment:
Performance Deficiency: The licensees failure to adequately implement requirements in procedure 0PGP03-XS-0001, Switchyard Management, revision 11, to ensure adequate oversight of switchyard component maintenance was a performance deficiency. Specifically, the licensee failed to ensure that coatings of switchyard insulators were maintained. This degraded condition resulted in flashovers which caused a de-energization of the switchyard south electrical bus and starting of safety-related equipment.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Equipment Performance attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the licensee failed to oversee the preventive maintenance of switchyard component which caused flashovers of three different insulators.
Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power.
Specifically, in Exhibit 1, "Initiating Events Screening Questions," the inspectors determined that this finding is of very low safety significance (Green), because it did not cause a reactor trip and the loss of mitigating equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition.
Cross-Cutting Aspect: Not Present Performance. No cross-cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance. The licensee was in the process of planning and scheduling corrective actions for the first flashover when the second flashover occurred.
Enforcement:
Inspectors did not identify a violation of regulatory requirements associated with this finding.
