==INSPECTION RESULTS==
Failure to Enter Turbine Building Degradation in the Corrective Action Program Cornerstone Significance Cross-cutting Aspect Report Section Initiating Events
 
Green FIN 05000280,05000281/2019001-01 Open/Closed
 
[H.13] -
Consistent Process 71153 A self-revealed Green finding was identified when the licensee failed to document, evaluate and implement adequate corrective actions in accordance with PI-AA-200, Corrective Action Program (CAP), upon discovery of the degraded turbine building (TB)roof. Subsequently, TB roofing material contacted the A reserve service station transformer (RSST) during tropical storm Michael on October 11, 2018, which caused electrical isolation of the A RSST, the D transfer bus and the 1J 4kV emergency bus.
 
=====Description:=====
On October 11, 2018, degraded TB roofing material contacted the A RSST and caused a pilot wire lockout signal which resulted in an undervoltage condition on the 1J 4kV emergency bus and subsequent automatic start of the #3 emergency diesel generator (EDG). At the time of the event, the site was experiencing rain and winds (approximately 55 miles per hour (mph)) associated with tropical storm Michael. The licensee evaluated this issue with a level of effort evaluation, CA 7407559. This evaluation determined, in part, that documentation and tracking of deficiencies associated with the TB roof, as identified in vendor inspection reports, have not been tracked in the CAP. The TB roof was determined to be degraded during a roof inspection by a vendor in 2016 and again in June of 2018. The vendor estimated the overall remaining life of the TB roof as 2 to 4 years following the roof inspections in 2016 and 2018, while noting specific deficiencies associated with loose flashing and loose or degraded fasteners. While the licensee did not track the TB roof condition in the CAP, the TB roof replacement project was tracked with the stations long range plan and originally planned to begin in 2017. It was subsequently rescheduled for 2019. The inspectors concluded that the licensee did not adequately evaluate the condition of the TB roof following the vendor inspections or implement a bridging strategy/interim corrective actions before the TB roof could be replaced. This was due in part, because the issue was not tracked in the stations CAP.
 
The licensee informed the NRC of the event on October 11, 2018 with licensee event report (LER) 05000280, 05000281/2018-002-00, Windblown Debris Caused Transformer Fault Resulting in Auto-Start of Emergency Diesel Generator in accordance with 10CFR50.73(a)(2)(iv)(A) and also made an 8-hour non-emergency event notification (EN
#53662) on October 12, 2018.
 
Corrective Actions: The licensee conducted inspections and tests of the A RSST and restored the normal alignment of the #3 EDG and the 1J emergency bus. TB roof repairs were made so that the damaged materials were replaced and new anchoring strips and fasteners were installed. The frequency of roof inspections has been increased until the roof is replaced, and all deficiencies are being entered into the CAP. The TB roof replacement project was scheduled to begin in 2020.
 
Corrective Action Reference: CR1107393
 
=====Performance Assessment:=====
Performance Deficiency: The licensee failed to document, evaluate and implement adequate corrective actions upon discovery of TB roof degradation in accordance with the corrective action program. Specifically, licensee procedure PI-AA-200, Corrective Action, Rev. 34 paragraph 3.1.4 required, in part, a condition report (CR) for any issue or concern that does not meet specific requirements of procedures, policies, management expectations, or accepted industry standards.
 
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors attribute of the Initiating Events cornerstone. Specifically, as a result of the PD and high winds at the site, degraded TB roofing material contacted the A RSST and caused a pilot wire lockout signal which resulted in an undervoltage condition on the 1J emergency bus and subsequent automatic start of the #3 emergency diesel generator (EDG) on October 11, 2018.
 
Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At - Power Situations. This finding was determined to be Green, very low safety significance, because the finding did not involve the complete or partial loss of a support system that contributed to the likelihood of, or cause, an initiating event that also affected mitigation equipment.
 
Cross-cutting Aspect: H.13 - Consistent Process: Individuals use a consistent, systematic approach to make decisions. Risk insights are incorporated as appropriate. The inspectors determined the finding had a cross-cutting aspect of Consistent Process in the Human Performance area because; while the licensee has conducted TB roof inspections, they were controlled informally and were not conducted or tracked by a procedure or preventive maintenance (PM) task/assignment.
 
=====Enforcement:=====
Inspectors did not identify a violation of regulatory requirements associated with this finding.
 
Observation 71153 The licensee conducted a level of effort evaluation (LEE) and determined the cause of the failed underground splice was poor craftsmanship by a company transmission team in 2009. To detect degradation of cabling, including splices, tan delta testing is performed on a six-year frequency.
 
The splice that failed had been tan delta tested satisfactorily in 2009 and 2012. During testing in 2018, a few days before the fault occurred, two separate test sets were used, both producing erratic results. These results were attributed to issues with the testing equipment. The licensee deferred the tan delta testing based on recommendations from electrical subject matter experts given tan delta testing was not required as a part of the reserve station service transformer (RSST)replacement project. The inspectors determined that cable splice degradation was identified by the erratic results and further testing could have identified the degraded splice prior to returning the RSST to service. After the cable fault and RSST lockout, all plant safety systems responded as designed. This observation was associated with closure of Licensee Event Report (LER) 2018-003-00, Auto-Start of Emergency Diesel Generators Due to Pilot Wire Lockout on 'C' Reserve Station Service Transformer.

[H.13] -

Consistent Process 71153 A self-revealed Green finding was identified when the licensee failed to document, evaluate and implement adequate corrective actions in accordance with PI-AA-200, Corrective Action Program (CAP), upon discovery of the degraded turbine building (TB)roof. Subsequently, TB roofing material contacted the A reserve service station transformer (RSST) during tropical storm Michael on October 11, 2018, which caused electrical isolation of the A RSST, the D transfer bus and the 1J 4kV emergency bus.

Description:

On October 11, 2018, degraded TB roofing material contacted the A RSST and caused a pilot wire lockout signal which resulted in an undervoltage condition on the 1J 4kV emergency bus and subsequent automatic start of the #3 emergency diesel generator (EDG). At the time of the event, the site was experiencing rain and winds (approximately 55 miles per hour (mph)) associated with tropical storm Michael. The licensee evaluated this issue with a level of effort evaluation, CA 7407559. This evaluation determined, in part, that documentation and tracking of deficiencies associated with the TB roof, as identified in vendor inspection reports, have not been tracked in the CAP. The TB roof was determined to be degraded during a roof inspection by a vendor in 2016 and again in June of 2018. The vendor estimated the overall remaining life of the TB roof as 2 to 4 years following the roof inspections in 2016 and 2018, while noting specific deficiencies associated with loose flashing and loose or degraded fasteners. While the licensee did not track the TB roof condition in the CAP, the TB roof replacement project was tracked with the stations long range plan and originally planned to begin in 2017. It was subsequently rescheduled for 2019. The inspectors concluded that the licensee did not adequately evaluate the condition of the TB roof following the vendor inspections or implement a bridging strategy/interim corrective actions before the TB roof could be replaced. This was due in part, because the issue was not tracked in the stations CAP.

The licensee informed the NRC of the event on October 11, 2018 with licensee event report (LER) 05000280, 05000281/2018-002-00, Windblown Debris Caused Transformer Fault Resulting in Auto-Start of Emergency Diesel Generator in accordance with 10CFR50.73(a)(2)(iv)(A) and also made an 8-hour non-emergency event notification (EN#53662) on October 12, 2018.

Corrective Actions: The licensee conducted inspections and tests of the A RSST and restored the normal alignment of the #3 EDG and the 1J emergency bus. TB roof repairs were made so that the damaged materials were replaced and new anchoring strips and fasteners were installed. The frequency of roof inspections has been increased until the roof is replaced, and all deficiencies are being entered into the CAP. The TB roof replacement project was scheduled to begin in 2020.

Corrective Action Reference: CR1107393

Performance Assessment:

Performance Deficiency: The licensee failed to document, evaluate and implement adequate corrective actions upon discovery of TB roof degradation in accordance with the corrective action program. Specifically, licensee procedure PI-AA-200, Corrective Action, Rev. 34 paragraph 3.1.4 required, in part, a condition report (CR) for any issue or concern that does not meet specific requirements of procedures, policies, management expectations, or accepted industry standards.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors attribute of the Initiating Events cornerstone. Specifically, as a result of the PD and high winds at the site, degraded TB roofing material contacted the A RSST and caused a pilot wire lockout signal which resulted in an undervoltage condition on the 1J emergency bus and subsequent automatic start of the #3 emergency diesel generator (EDG) on October 11, 2018.

Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At - Power Situations. This finding was determined to be Green, very low safety significance, because the finding did not involve the complete or partial loss of a support system that contributed to the likelihood of, or cause, an initiating event that also affected mitigation equipment.

Cross-cutting Aspect: H.13 - Consistent Process: Individuals use a consistent, systematic approach to make decisions. Risk insights are incorporated as appropriate. The inspectors determined the finding had a cross-cutting aspect of Consistent Process in the Human Performance area because; while the licensee has conducted TB roof inspections, they were controlled informally and were not conducted or tracked by a procedure or preventive maintenance (PM) task/assignment.

Enforcement:

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

Observation 71153 The licensee conducted a level of effort evaluation (LEE) and determined the cause of the failed underground splice was poor craftsmanship by a company transmission team in 2009. To detect degradation of cabling, including splices, tan delta testing is performed on a six-year frequency.

The splice that failed had been tan delta tested satisfactorily in 2009 and 2012. During testing in 2018, a few days before the fault occurred, two separate test sets were used, both producing erratic results. These results were attributed to issues with the testing equipment. The licensee deferred the tan delta testing based on recommendations from electrical subject matter experts given tan delta testing was not required as a part of the reserve station service transformer (RSST)replacement project. The inspectors determined that cable splice degradation was identified by the erratic results and further testing could have identified the degraded splice prior to returning the RSST to service. After the cable fault and RSST lockout, all plant safety systems responded as designed. This observation was associated with closure of Licensee Event Report (LER) 2018-003-00, Auto-Start of Emergency Diesel Generators Due to Pilot Wire Lockout on 'C' Reserve Station Service Transformer.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.
