Failure to Determine Extent of Cause Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems Green FIN 05000461/2020004-01 Open/Closed
[H.12] - Avoid Complacency 71152 The inspectors identified a Green finding when the licensee failed to determine the extent of cause for a root cause in accordance with PI-AA-125-1001, "Root Cause Analysis Manual," Revision 6. Specifically, the licensee failed to identify that lack of technical rigor in the station's FLEX modification caused the FLEX output breaker settings to have been left at factory settings without an analysis.
Additional Tracking Items
None.
PLANT STATUS
Unit 1 operated at or near rated thermal power for the entire 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. 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 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.
Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the Coronavirus Disease 2019 (COVID-19), resident inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status; observed risk-significant activities; and completed on-site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on-site. The inspections documented below met the objectives and requirements for completion of the IP.

INSPECTION RESULTS
Failure to Determine Extent of Cause Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems
Green FIN 05000461/2020004-01 Open/Closed
[H.12] - Avoid Complacency 71152 The inspectors identified a Green finding when the licensee failed to determine the extent of cause for a root cause in accordance with PI-AA-125-1001, "Root Cause Analysis Manual,"
Revision 6. Specifically, the licensee failed to identify that lack of technical rigor in the station's FLEX modification caused the FLEX output breaker settings to have been left at factory settings without an analysis.
Description:
On June 26, 2020, the licensee wrote Action Request 4352937 documenting that the FLEX diesel generator output breakers did not have an engineering analysis to determine the correct breaker settings. Both FLEX diesel generator output breakers were still set to the factory default settings. Upon discovery of the condition, it was uncertain if the FLEX diesel generators would have been able to supply power without tripping the output breaker. The licensee evaluated the condition and determined that the breaker would not trip if it were supplying power and that there was less margin in the calculation than would normally be acceptable. The licensee adjusted the breaker settings to provide a more acceptable margin.
The licensee performed a corrective action program evaluation for the condition and identified that the breaker settings were not discussed in Engineering Change 392335, which installed the breakers. The licensee determined that the cause was less than adequate technical rigor by the engineer responsible for the FLEX modification. The inspectors noted that this cause was nearly identical to the cause identified in Root Cause Report 4297570 for the FLEX diesel generator 1FX01KA being wired with its phase rotation out of phase from the plant equipment phase rotation. The phase rotation issue was previously identified as a Green finding identified in NRC integrated inspection report 05000461/2020001 as FIN 05000461/2020001-01 "FLEX Diesel Generator Phase Rotation Incorrect."
The inspectors reviewed Root Cause Report 4297570 to determine the similarities between the FLEX diesel generator phase rotation issue and the output breaker settings issue. The root cause identified was that engineers did not apply technical human performance fundamentals during selection of post-modification testing for the FLEX modification. The licensee conducted an extent-of-cause review for the root cause in accordance with PI-AA-125-1001, "Root Cause Analysis Manual," Revision 6. The extent-of-cause review evaluated all modifications that were completed by the responsible engineers to verify that post-modification testing was correct. The extent-of-cause did not review the modifications to verify overall adequacy or that the appropriate engineering rigor was applied to areas outside of post-modification testing.
Exelon procedure PI-AA-125-1006, "Investigation Techniques Manual," Revision 5, includes considerations for performing an extent-of-cause review. The manual stresses the importance of identifying how a cause could affect programs or processes other than the one that was already identified. When the licensee focused their extent-of-cause review on the adequacy of post-modification testing, they did not consider how the cause could affect other processes or programs that could have been affected by lack of technical rigor in implementing the FLEX modification. Specifically, the review did not identify that Engineering Change 392335 did not provide any analysis of the FLEX breakers; therefore, the breakers did not have any discussion for post-modification testing.
Corrective Actions: The licensee determined correct breaker settings and performed the change to support breaker functionality.
Corrective Action References: Action Request 4352937, "FLEX Diesel Generator Breaker Settings"
Performance Assessment:
Performance Deficiency: The licensee failed to determine the extent of cause for a root cause as required by PI-AA-125-1001. This led to the licensee failing to identify that the FLEX diesel generator output breaker settings were not evaluated and were set to factory default settings instead of site-specific settings.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Design Control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, there was reasonable doubt as to the functionality of the FLEX generator output breakers until a detailed analysis was performed, and following the analysis, the licensee determined that the settings should be revised. This was similar to example 3.a in Inspection Manual Chapter 0612, Appendix E, "Examples of Minor Issues."
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors used Exhibit 2, "Mitigating Systems Screening Questions," Section E "Flexible Coping Strategies (FLEX)," and answered "No" to all questions. Therefore, the finding screens to Green or very low safety significance.
Cross-Cutting Aspect: H.12 - Avoid Complacency: Individuals recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Individuals implement appropriate error reduction tools. Specifically, when the licensee attempted to identify the extent of cause for the FLEX diesel generator phase rotation issue; they only focused on post-modification testing and did not attempt to identify other areas where lack of technical rigor could have impacted the FLEX implementation.
Enforcement:
Inspectors did not identify a violation of regulatory requirements associated with this finding.
Observation: Unplanned Reactivity Events in 2020 71152 The inspectors observations and assessments of trends related to several unplanned power changes over 2020 indicated an inconsistent range of response in assessment as well as communication with the support organizations and management. The inspectors determined that the lack of an off normal procedure to address unplanned power changes impacted the consistent application of process in both response and communication. All minor issues with each event were individually addressed in the quarter in which they occurred during the quarterly exits. The station did take note of the inspectors observations regarding the response to these events and is developing an off normal response procedure for unplanned power changes. The procedure is slated for completion by the first half of
