SUBJECT:
GRAND GULF NUCLEAR STATION - INTEGRATED INSPECTION REPORT 05000416/2019002
Dear Mr. Larson:
On June 30, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Grand Gulf Nuclear Station. On July 11, 2019, the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.
The NRC inspectors documented one finding of very low safety significance (Green) in this report. The finding did not involve a violation of NRC requirements. Additionally, NRC inspectors documented one Severity Level IV violation with no associated finding. The NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2 of the Enforcement Policy.
Inspection Procedure 92723, Follow up Inspection for Three or More Severity Level IV Traditional Enforcement Violations in the Same Area in a 12-Month Period, was performed during this inspection period to assess your evaluation of 10 previously issued violations in the area of impeding the regulatory process, and to assess the adequacy of associated corrective actions. Based on the results of this inspection, which are documented in the enclosed report, the NRC was not able to conclude that the actions taken were adequate to meet the inspection objectives. Therefore, additional inspection will be performed to continue this review under Inspection Procedure 92723 upon notification of your readiness. The additional Severity Level IV violation documented in the enclosed report, which is also in the area of impeding the regulatory process, will be included in the scope of this traditional enforcement follow-up inspection.
If you contest the violation or severity of the violation documented in this inspection report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; the Director, Office of Enforcement; and the NRC Resident Inspector at Grand Gulf. If you disagree with a cross-cutting aspect assignment or a finding not associated with a regulatory requirement in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; and the NRC Resident Inspector at Grand Gulf.
This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

List of Findings and Violations
Failure to Update the UFSAR Cornerstone Severity Cross-Cutting Aspect Report Section Not Applicable Severity Level IV NCV 05000416/2019002-01 Closed Not Applicable 71111.05Q The inspectors identified a Severity Level IV, non-cited violation of 10 CFR 50.71(e) for the licensee's failure to update the Updated Final Safety Analysis Report, Section 9A.5.
The inspectors identified over 20 discrepancies between the fire zone descriptions in the Updated Final Safety Analysis Report and the licensee's implementing documents, including Procedure 06-OP-SP64-R-0047, Fire Rated Assembly Visual Inspection, Revision 116. The licensee periodically updated fire protection implementing procedures but did not update the Updated Final Safety Analysis Report, when needed, to reflect those changes.
Failure to Follow Design Control Procedure Cornerstone Significance Cross-Cutting Aspect Report Section Initiating Events Green FIN 05000416/2019002-02 Closed
[H.6] - Design Margins 71152 A self-revealed, Green finding was identified when an actuation of the generator protection negative phase sequence trip caused a generator lockout and a reactor scram. The licensee failed to ensure that a recent change in the applicable trip setpoint was managed in accordance with Procedure EN-DC-115, Engineering Change Process, Revision 21. The licensee failed to identify, evaluate, and manage a reduction in operating margin associated with the negative phase sequence trip setpoint. The setpoint was reduced from 9 percent to percent as part of a digital upgrade modification; however, the licensee failed to fully evaluate the change. As a result, routine grid operations above 5 percent negative phase sequence were unmanaged and ultimately led to an unplanned reactor scram.

PLANT STATUS
Unit 1 began the inspection period at full power. On April 6, 2019, operators reduced power to approximately 56 percent for control rod pattern adjustments. Full power operation resumed on April 8, 2019. On April 9, 2019, to allow for repair of a high pressure feedwater heater leak, power was reduced to approximately 66 percent. Power was increased to approximately 94 percent on April 12, 2019, with the high pressure feedwater heaters isolated. On April 16, 2019, power was reduced to approximately 65 percent to perform power suppression testing. Following repairs to the feedwater heater and power suppression testing, the unit reached full power on April 21, 2019. On May 12, 2019, due to a significant loss of plant service water, operators manually shut down the unit. Following repairs to the plant service water electrical distribution system, the unit was started up on May 19, 2019, and full power was achieved on May 30, 2019. On June 26, 2019, in order to support replacement of a recirculation flow control valve controller, operators reduced power to approximately 96 percent.
On June 27, 2019, the unit reached full power and remained at or near full 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.

These violations involved accuracy and completeness of the Updated Final Safety Analysis Report, accuracy and completeness of information in the license renewal process, failure to report changes to the emergency plan, and failure to obtain a license amendment as required.
The inspectors also noted that from January 1 to December 31, 2015, the NRC issued seven Severity Level IV traditional enforcement violations associated with impeding the regulatory process, as documented in Annual Assessment Letter 05000416/2015006 (ADAMS Accession No. ML16061A361), dated March 2, 2016. Inspection Procedure 92723 was again performed in response to these Severity level IV traditional enforcement violations, as documented in NRC Inspection Report 05000416/2016003 (ADAMS Accession No. ML16315A372), dated November 10, 2016. These violations involved two failures to update the Final Safety Analysis Report; a failure to maintain a safety-related cable tray overfill analysis record; an incomplete and inaccurate response to NRC Bulletin 88-04; a failure to obtain a license amendment; and two failures to make required event notifications or reports.
Considering these facts, the inspectors sought to understand why failures to update the Final Safety Analysis Report, failures to make required reports, and failures to obtain license amendments were issues that have continued to be identified and documented as recently as 2019.
Licensee Evaluation
The inspectors reviewed the licensees collective evaluations (completed at the Condition Analysis level) associated with the 10 CFR 50.59 issues and reporting issues, which included 10 CFR 50.71(e) and reporting issues. The inspectors also reviewed individual/combined evaluations associated with each of the 10 non-cited violations. The inspectors were not able to review in detail the latest revisions of the collective evaluation associated with Condition Report CR-GGN-2019-01002 (associated with 50.59 issues) and the adverse condition analysis associated with Condition Report CR-GGN-2018-01595 (associated with a late 8-hour notification) because preliminary versions of the evaluations were provided during the inspection. Evaluations reviewed included:
- CR-GGN-2019-01002, 50.59 Evaluations not Conducted as Required, which evaluated the causes of 10 CFR 50.59 related violations (three issues with four total examples). CR-GGN-2017-01483 had previously been completed to address this group of issues. The individual issues included within this collective evaluation were evaluated by the following cause evaluations:
1. CR-GGN-2019-01007, dated March 14, 2019, which revised the licensees
evaluations associated with CR-GGN-2016-09757 (two revisions); these cause evaluations were associated with violation (3), as listed above.
2. CR-GGN-2019-01185, dated March 20, 2019, which revised the licensees
evaluations associated with CR-GGN-2016-08298 (two revisions); these cause evaluations were associated with violations
- (1) and (2), as listed above.
- CR-GGN-2019-01003, Failure to Submit Reports to the NRC, which evaluated the causes of failures to make reports to the NRC (five issues/examples) and failures to update the Final Safety Analysis Report (two issues with four total examples).
CR-GGN-2017-07970 had previously been completed to address this group of issues.
The individual issues included within this collective evaluation were evaluated by the following cause evaluations:
1. CR-GGN-2017-03404, dated May 22, 2017, and later revised on
March 1, 2019; this cause evaluation was associated with violations
- (5) and (6), as listed above
2. CR-GGN-2017-12284, dated February 20, 2018, and later revised on
March 1, 2019; this cause evaluation was associated with violation (8), as listed above
3. CR-GGN-2018-01595, dated March 27, 2018, and later revised March 1, 2019;
this cause evaluation was associated with violation (9), as listed above
4. CR-GGN-2019-01047, dated March 22, 2019; this cause evaluation was
associated with violation (10), as listed above
5. CR-GGN-2019-01390, dated March 1, 2019, which elevated the level of
evaluation of CR-GGN-2017-03092, which was documented on March 27, 2017, at the C significance level; these were associated with violation (4), as listed above
6. CR-GGN-2019-01391, dated March 14, 2019, which elevated the level of
evaluation of CR-GGN-2017-03331, which was documented on April 4, 2017, at the C significance level; these were associated with violation (7), as listed above
Assessment
Considering all the cause evaluations and relevant condition reports the inspectors identified 16 examples where the responsible manager failed to ensure all available and relevant information was acquired by reviews of pertinent industry events in accordance with step 4[2]e of Procedure EN-LI-118, Cause Evaluation Process, Revision 23. The licensee documented Condition Reports CR-GGN-2019-02684, CR-GGN-2019-02716, CR-GGN-2019-02733 to address these concerns. These examples included:
- Failure to review all relevant condition reports (such as CR-GGN-2015-05057) in the relevant internal operating experience section of the adverse condition analyses associated with CR-GGN-2019-01002 and CR-GGN-2019-01003
- Failure to review 17 relevant condition reports in the relevant internal operating experience section of the adverse condition analysis associated with CR-GGN-2017-12284
- Failure to include relevant internal operating experience detailed review attachments with the adverse condition analyses associated with CR-GGN-2017-12284, CR-GGN-2017-03404, CR-GGN-2019-01391, and CR-GGN-2018-01595
- Failure to perform internal operating experience repeat event reviews with the adverse condition analyses associated with CR-GGN-2018-01390, CR-GGN-2019-01047, and CR-GGN-2019-01391
- Failure to perform an adequate review of external operating experience with the adverse condition analyses associated with CR-GGN-2017-03404 and CR-GGN-2018-01390
- Failure to include relevant external operating experience detailed review attachments with the adverse condition analyses associated with CR-GGN-2017-12284, CR-GGN-2017-03404, CR-GGN-2019-01391, and CR-GGN-2018-01595
The inspectors also identified other issues during the review:
- The inspectors identified that Attachment 9.2, UFSAR Change Process Flow Chart, of Procedure EN-LI-113-01, Updated Final Safety Analysis Report Change Process, Revision 3, included numerous incorrect procedure step references. The licensee documented CR-GGN-2019-02674 to address the concern.
- The inspectors identified that a corrective action was not implemented to address a missed barrier identified as a factor in adverse condition analysis CR-GGN-2018-01595. This was associated with providing a procedure barrier to operators and licensing personnel when completing reportability evaluations. The licensee initiated CR-GGN-2019-02690 to address this observation.
- The licensee initiated CR-GGN-2019-02732 in response to the inspectors' questions on licensing basis document change request (LBDCR)/Updated Final Safety Analysis Report tracking not being defined.
Conclusions
The inspectors could not conclude that the inspection objectives were met because substantially relevant operating experience was not adequately considered and evaluated by the licensee when determining causes, extent of conditions, extent of causes, or corrective actions. Specifically, the inspectors identified that the conditions, scope, and causes associated with the two main collective evaluations and the previously performed root cause CR-GGN-2015-05057, which was associated with previous examples of incorrect maintenance of design and license basis documents, revealed substantive commonalities involving implementation and control of design change and license basis document changes; however, the CR-GGN-2015-05057 root cause analysis was not appropriately evaluated as relevant operating experience in the current evaluations. Corrective actions to prevent recurrence of root causes would be expected to prevent recurrence of the same performance deficiency.
Additionally, the licensee continues to identify LBDCR performance issues. Specifically, engineering changes with LBDCRs are still being evaluated to ensure all LBDCRs from 2000-2013 are appropriately tracked and coordinated. Also, a trend of incorrectly implemented LBDCRs during a software conversion is still being evaluated to determine causes and to ensure that conversion issues have been identified.
Finally, the inspectors could not conclude that the inspection objectives were met because the collective evaluations and additional causal analyses were being revised as of the completion of the inspection. As a result of this inspection, the licensee voluntarily determined that the conclusions of its collective evaluations needed to be reconsidered. The licensee planned to re-evaluate and revise its collective evaluations (CR-GGN-2019-01002 and CR-GGN-2019-01003) associated with the 10 violations and review the previous CR-GGN-2015-05057 root cause analysis to ensure that the causes, extent of conditions, extent of causes, and corrective actions were adequate. The licensee initiated CR-GGN-2019-02717 to document that adverse condition analyses associated with CR-GGN-2019-01002 and CR-GGN-2019-01003 did not adequately evaluate issues with configuration control of design and licensing basis documentation. The licensee informed the inspectors that a cause evaluation will be completed to address this concern.
Failure to Update the UFSAR Cornerstone Severity Cross-Cutting Aspect Report Section Not Applicable Severity Level IV NCV 05000416/2019002-01 Closed Not Applicable 71111.05Q The inspectors identified a Severity Level IV, non-cited violation of 10 CFR 50.71(e) for the licensee's failure to update the Updated Final Safety Analysis Report, Section 9A.5.
The inspectors identified over 20 discrepancies between the fire zone description in the Updated Final Safety Analysis Report and the licensee's implementing documents, including Procedure 06-OP-SP64-R-0047, Fire Rated Assembly Visual Inspection, Revision 116. The licensee periodically updated fire protection implementing procedures but did not update the Updated Final Safety Analysis Report, when needed, to reflect those changes.
Description:
While reviewing the fire rated assembly visual inspection criteria contained in Procedure 06-OP-SP64-R-0047, the inspectors identified discrepancies between the procedure and the Updated Final Safety Analysis Report (UFSAR), Section 9A.5.
Specifically, the inspectors compared the fire barrier descriptions of 125 out of 266 fire zones described in UFSAR, Section 9A.5, with the surveillance requirements contained in Procedure 06-OP-SP64-R-0047. From this review, the inspectors identified discrepancies with 24 fire zones. The inspectors found that in some instances, the procedure classified various barriers as 3-hour fire barriers required by the technical requirements manual, while the UFSAR described them as non-rated barriers.
For example, Procedure 06-OP-SP64-R-0047 described the ceiling as a fire-rated barrier for Fire Zones 1A115 and 1A116 that was required to remain functional per the technical requirements manual. Fire Zones 1A115 and 1A116 both included the ceiling as a required barrier in the procedure because the ceiling interfaces with a fire zone in a different fire area; however, the UFSAR descriptions for Fire Zones 1A115 and 1A116 both stated that the ceiling is a non-rated barrier in those fire zones. Likewise, the west walls for Fire Zones 1A130 and 1A131 separated these zones from a different fire area and were described as required fire barriers in Procedure 06-OP-SP64-R-0047; however, the UFSAR stated that these walls were not rated barriers.
While reviewing the revision history of this procedure, the inspectors learned that the licensee had previously identified numerous discrepancies with this procedure and documented the issues in Condition Report CR-GGN-2000-00585 on April 28, 2000. Corrective actions included revising the procedure to reflect the fire barriers required to remain operable per Technical Requirements Manual 6.2.8, but the licensee did not ensure that the UFSAR was revised to remain consistent with the procedure.
Corrective Actions: The licensee performed an apparent cause analysis and initiated a review to identify all discrepancies between the UFSAR and Procedure 06-OP-SP64-R-0047.
Corrective actions planned included evaluating all the identified discrepancies and revising the procedure and/or the UFSAR as warranted by the nature of each discrepancy.
Corrective Action References: The licensee entered the issue into their corrective action program as Condition Report CR-GGN-2019-02719, 2019-02427, and 2019-02471
Performance Assessment:
The inspectors determined this violation was associated with a minor performance deficiency.
Enforcement:
The ROPs significance determination process does not specifically consider the regulatory process impact in its assessment of licensee performance. Therefore, it is necessary to address this violation which impedes the NRCs ability to regulate using traditional enforcement to adequately deter noncompliance.
Severity: This violation was determined to be Severity Level IV in accordance with the NRC Enforcement Policy, Example 6.1.d.3. The inspectors determined that there was a material impact on safety or licensed activities because if utilized, lack of up-to-date information in the UFSAR could have a nonconservative impact on design analyses.
Violation: As required by 10 CFR 50.71, Maintenance of Records, Making of Reports, Section (e), Each person licensed to operate a nuclear power reactor shall update periodically the Final Safety Analysis Report originally submitted as part of the application for the license, to assure that the information included in the report contains the latest information developed. This submittal shall contain all the changes necessary to reflect information and analyses submitted to the Commission by the applicant or licensee or prepared by the applicant or licensee pursuant to Commission requirement since the submittal of the original or the last update to the Final Safety Analysis Report. Contrary to the above, since April 28, 2000, the licensee did not update the Final Safety Analysis Report to assure that the information included in the report contains the latest information developed.
Specifically, the licensee failed to update the Final Safety Analysis Report with the most up-to-date fire barrier descriptions both during and after the resolution of Condition Report CR-GGN-2000-00585.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Follow Design Control Procedure Cornerstone Significance Cross-Cutting Aspect Report Section Initiating Events
Green FIN 05000416/2019002-02 Closed
[H.6] - Design Margins 71152 A self-revealed, Green finding was identified when an actuation of the generator protection negative phase sequence trip caused a generator lockout and a reactor scram. The licensee failed to ensure that a recent change in the applicable trip setpoint was managed in accordance with Procedure EN-DC-115, Engineering Change Process, Revision 21. The licensee failed to identify, evaluate, and manage a reduction in operating margin associated with the negative phase sequence trip setpoint. The setpoint was reduced from 9 percent to 5 percent as part of a digital upgrade modification; however, the licensee failed to fully evaluate the change. As a result, routine grid operations above 5 percent negative phase sequence were unmanaged and ultimately led to an unplanned reactor scram.
Description:
On February 23, 2019, an automatic reactor scram occurred as a result of a turbine trip. The licensee determined that a generator lockout caused the turbine trip and that the generator lockout was caused when the generator negative phase sequence protection portion of the generator protective relays 1N41M711A/B and 1N41M712A/B actuated. The relays actuated when the generator phase unbalance exceeded the trip setpoint of 5 percent.
The licensee entered the issue in their corrective action program as Condition Report CR-GGN-2019-01504.
In February 1981, the generator negative phase sequence setpoint was determined to be 9 percent as documented in Calculation PR0204, Revision 0. Although the calculation determined that a setpoint of 5 percent was acceptable, physical device limitations precluded the setpoint to be set any lower than 9 percent. This setpoint was revisited on May 5, 2012, when Revision 2 to Calculation PR0204 was issued as part of Engineering Change (EC) 20838. As part of this calculation, the trip threshold was retained at 9 percent based on industry guidance and previous settings.
In May 2016, the licensee initiated a project to upgrade the analog generator protective relaying scheme to digital. The licensee hired a contractor to perform the engineering change as documented in EC 67304 using the licensees change control program and procedures.
As a part of this modification, Calculation EC-N1N41-17001 determined that the negative phase sequence trip setpoint should be changed to 5 percent; however, there was no discussion or evaluation on the effects that reducing the setpoint from 9 percent to 5 percent would have on operating margin. Had the licensee thoroughly reviewed the setpoint change, operating experience available at the time would have identified that the local electrical grid is routinely operated at greater than 5 percent unbalance. Such a review would have prompted a more thorough evaluation of the impacts of lowering the setpoint to a value that could routinely be exceeded during normal power operations.
At the time EC 67304 was issued, licensee Procedure EN-DC-115, "Engineering Change Process," Revision 21, required that the responsible engineer describe the impact on plant operating margins. One of the impact screening criteria in Attachment 9.4 of Procedure EN-DC-115 included, Change protective relay settings, generator exciter or Automatic Voltage Regulator (AVR) settings. Although this box was checked in conjunction with the licensee's implementation of EC 67304, the inspectors could find neither an evaluation for the effects of changing this setpoint nor an evaluation for the effects of a reduced operating margin as a result of the setpoint reduction.
The licensee performed a root cause evaluation and concluded that the root cause was that engineering leadership did not ensure standards and expectations for adherence to a systematic and rigorous configuration change process were met to maintain operating margins and achieve an acceptable result to prevent an unplanned scram. Contributing causes were determined to be the failure of electrical design engineers to follow the configuration control process as described in Procedure EN-DC-115.
The licensee determined, based on previous operating experience and equipment limitations, that a setpoint of 9 percent was acceptable to provide an adequate level of protection to the generator equipment while still maintaining an acceptable operational margin to prevent spurious trips on generator negative phase sequence from normal grid operating conditions.
As a result, the licensee issued EC 81801 to change the trip setpoint back to 9 percent, which was completed under Work Order 00519151 on February 27, 2019.
Corrective Actions: Licensee corrective actions included performing a root cause evaluation, which resulted in procedure changes and training of applicable engineering staff. The negative phase setpoint was changed back to 9 percent.
Corrective Action References: The licensee entered the issue into their corrective action program as Condition Report CR-GGN-2019-01504.
Performance Assessment:
Performance Deficiency: The licensees failure to follow the configuration control process as described in licensee Procedure EN-DC-115 is a performance deficiency. Because the licensee did not effectively evaluate the impact of reducing generator protective relay setpoints, operating margins were not managed as required by Procedure EN-DC-115.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Design Control attribute of the Initiating Events cornerstone. Specifically, the performance deficiency contributed to an unplanned automatic reactor scram.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Specifically, because the finding only caused a reactor trip but not the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition, the finding was determined to be of very low safety significance (Green).
Cross-Cutting Aspect: H.6 - Design Margins: The organization operates and maintains equipment within design margins. Margins are carefully guarded and changed only through a systematic and rigorous process. Special attention is placed on maintaining fission product barriers, defense-in-depth, and safety related equipment. Specifically, the licensee failed to carefully guard margins and did not employ a systematic and rigorous process to control operational margins when developing, reviewing, approving, and implementing EC 67304.
Enforcement:
Inspectors did not identify a violation of regulatory requirements associated with this finding.
