SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a quarterly inspection at Grand Gulf Nuclear 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. A violation and additional items being considered in the NRCs assessment are summarized in the tables below.

List of Findings and Violations Failure to Scope Standby Service Water Piping into the Inspection Program Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green [H.1] - Resources 71111.19 Systems NCV 05000416/2019001-01 Closed A self-revealed, Green finding and associated non-cited violation of 10 CFR Part 50,

Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when a pinhole leak developed in a portion of the standby service water piping. The licensee failed to ensure that general erosion in the service water piping immediately downstream of the Division 1 emergency diesel generator heat exchanger outlet valve was identified, trended, and managed as required by licensee Procedure EN-DC-184, NRC Generic Letter 89-13 Service Water Program, Revision 5.

The licensee failed to appropriately scope this pipe into their Generic Letter 89-13 program and, therefore, failed to perform the monitoring as required by Procedure EN-DC-184. As a result, unrecognized cavitation-induced erosion caused gradual pipe wall thinning until the piping developed a pinhole leak, which rendered the Division 1 standby service water system inoperable.

INSPECTION RESULTS

Failure to Scope Standby Service Water Piping into the Inspection Program Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green [H.1] - 71111.19 Systems NCV 05000416/2019001-01 Resources Closed A self-revealed, Green finding and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when a pinhole leak developed in a portion of the standby service water piping. The licensee failed to ensure that general erosion in the service water piping immediately downstream of the Division 1 emergency diesel generator heat exchanger outlet valve was identified, trended, and managed as required by licensee Procedure EN-DC-184, NRC Generic Letter 89-13 Service Water Program, Revision 5.

The licensee failed to appropriately scope this pipe into their Generic Letter 89-13 program and, therefore, failed to perform the monitoring as required by Procedure EN-DC-184. As a result, unrecognized cavitation-induced erosion caused gradual pipe wall thinning until the piping developed a pinhole leak which rendered the Division 1 standby service water system inoperable.

Description:

On January 6, 2019, operators received a standby service water (SSW) head tank make up annunciator in the main control room, which was indicative of a SSW leak.

Upon investigating, operators identified an approximately half gallon per minute leak in the SSW piping downstream of the Division 1 emergency diesel generator (EDG) heat exchanger outlet valve 1P41F023A. The licensee entered the issue in their corrective action program as Condition Report CR-GGN-2019-00096.

After performing ultrasonic testing of the affected area, the licensee determined that they were not able to apply American Society of Mechanical Engineers (ASME) Code Case N-513 to evaluate structural integrity of the piping and declared both the Division 1 SSW system and the Division 1 EDG inoperable. The licensee removed and replaced the affected potion of piping under Work Order 00515589.

The licensee hired a consultant to perform a structural analysis on the failed section of piping.

The consultant determined that the failure was due to long-term cavitation-induced erosion from high fluid velocities immediately downstream of valve 1P41F023A. Valve P41F023A was a butterfly valve that was throttled to achieve desired system flow rates for total system flow balance and operated in such a manner since original plant startup. This operating history caused the valve to remain in nearly the same position for long periods of time, thus inducing the cavitation erosion inside the pipe. The consultant also determined that corrosion likely exacerbated the wall thinning while the system was in a standby condition.

The licensee performed an equipment failure evaluation and determined that the failed section of pipe should have been included in their Generic Letter (GL) 89-13 monitoring program because the pipe was immediately downstream of a throttled butterfly valve and because of industry operating experience of failures in similar sections of pipe. The licensee was unable to specifically identify exactly why the pipe was originally excluded from the program but determined that ineffective oversight of the program contributed to its continued exclusion. Because the pipe was never properly scoped into the GL 89-13 program, the licensee was not periodically inspecting the pipe and therefore failed to identify the erosion until the pinhole leak developed.

The inspectors reviewed licensee Procedure EN-DC-184, NRC Generic Letter 89-13 Service Water Program, Revision 5, which established the service water monitoring expectations and guidelines. Step 5.0[3](b) of Procedure EN-DC-184 stated, in part, that service water activities must ensure that degradation due toerosion...is identified, trended, and managed in a controlled fashion. Furthermore, Attachments 2 and 3 of Procedure EN-DC-184 provided program element details and selection criteria for inclusion into the monitoring program for service water piping adjacent to throttled valves.

On April 29, 1994, Procedure MS-46, Program Plan for Monitoring Internal Erosion and/or Corrosion in Moderate Energy Piping Components, was revised to include SSW components but did not include the section of pipe that ultimately developed a pinhole leak. The licensee later developed Procedure EN-DC-184 and issued it on September 21, 2009, but continued to exclude this section of pipe from the overall GL 89-13 program.

In 2012, Condition Report CR-GGN-2012-12636 identified that although Procedure MS-46 was active, it was not being effectively implemented. Corrective actions included updating the MS-46 database of pipe wall thickness measurements and erosion trends; however, these efforts did not identify the lack of clear program oversight and ownership which likely contributed to the lack of effective implementation.

In 2017, the licensee hired a consultant to perform an erosion susceptibility evaluation of the plant. The initial report was provided to the licensee in November 2017, and Revision 1 was provided in May 2018. However, the licensee neither formally accepted nor acted upon the report until station management became aware that the report existed after the pinhole leak developed.

The inspectors determined that the failure to properly scope all service water program activities into the GL 89-13 program was because licensee management failed to ensure that personnel, procedures, and other resources were available and adequate to support the erosion monitoring portion of their GL 89-13 program. For this aspect of the licensees GL 89-13 program, there was neither clearly defined roles and responsibilities nor a clear program owner.

Corrective Action(s): Licensee corrective actions included replacing the section of piping and restoring the system to service, performing an equipment failure evaluation, performing a structural analysis of the failed piping, developing an extent of condition inspection plan for similar throttled valves in the SSW system, adding piping downstream of throttled valves into the scope of the EN-DC-184 program, and developing clear roles and responsibilities for the oversight of the erosion monitoring program.

Corrective Action Reference(s): The licensee entered the issue into their corrective action program as Condition Report CR-GGN-2019-00096.

Performance Assessment:

Performance Deficiency: The failure to scope the SSW piping downstream of the Division 1 EDG heat exchanger outlet valve into an erosion monitoring plan as required per Procedure EN-DC-184 is a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the performance deficiency contributed to the inoperability of the Division 1 standby service water system.

Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609 Appendix A, Significance Determination of Reactor Inspection Findings for At - Power Situations. Since the finding did not affect the design or qualification and did not represent a loss of system function, the inspectors determined that the finding was of very low safety significance (Green). Specifically, the Division 2 SSW system was not affected, and the Division 1 SSW system was still able to provide adequate cooling to the Division 1 emergency diesel generator.

Cross-cutting Aspect: The finding had a cross-cutting aspect in the area of human performance associated with resources because licensee management failed to ensure that personnel, procedures, and other resources were available and adequate to support the service water piping erosion monitoring portion of their GL 89-13 program. Although the cause of the initial scoping failure dates back to approximately 1994, the inspectors concluded that it is indicative of current licensee performance because of the failure to provide adequate oversight of the 2017 erosion susceptibility evaluation [H.1].

Enforcement:

Violation: As required by 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, activities affecting quality shall be prescribed by documented procedures and shall be accomplished in accordance with these procedures. Licensee Procedure EN-DC-184, NRC Generic Letter 89-13 Service Water Program, Revision 5, a quality related procedure, was used to establish and implement the safety-related service water monitoring program. Step 5.0[3](b) of Procedure EN-DC-184 stated, in part, that service water program activities must ensure that degradation due togeneral corrosion

[and] erosion...is identified, trended, and managed in a controlled fashion.

Contrary to the above, from September 21, 2009, through January 6, 2019, the licensees service water program activities failed to ensure that degradation due to general corrosion and erosion was identified, trended, and managed in a controlled fashion in accordance with Procedure EN-DC-184. Specifically, the licensee failed to monitor the safety-related service water pipe downstream of valve 1P41F023A for general corrosion and erosion.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
