VOGTLE ELECTRIC GENERATING PLANT, UNITS 3 AND 4 - NRC INTEGRATED INSPECTION REPORTS 05200025/2020004, 05200026/2020004

Dear Mr. Yox:

On December 31, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the Vogtle Electric Generating Plant (VEGP), Units 3 and 4. The enclosed inspection report documents the inspection results, which the inspectors discussed on January 14, 2021, with Mr. Glen Chick, VEGP Units 3 and 4, Executive Vice President, and other licensee and contractor staff members.

The inspection examined a sample of construction activities conducted under your Combined License (COL) as it relates to safety and compliance with the Commissions rules and regulations and with the conditions of these documents. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

NRC inspectors documented two findings of very low safety significance (Green). Both of these findings involved violations of NRC requirements. The NRC is treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy.

If you contest the violations or significance of these NCVs, 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 II; the Director, Office of Enforcement; and the NRC resident inspector at the VEGP Units 3 and 4.

If you disagree with a cross-cutting aspect assignment 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 II; and the NRC resident inspector at the VEGP Units 3 and 4.

M. Yox 2 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.

SUMMARY

OF FINDINGS Inspection Report (IR) 05200025/2020004, 05200026/2020004; 10/01/2020 through 12/31/2020; Vogtle Unit 3 Combined License, Vogtle Unit 4 Combined License, Integrated Inspection Report.

This report covers a three-month period of inspection by regional and resident inspectors.

Two findings of very low safety significance (Green), each with an associated non-cited violation (NCV) of NRC requirements, were identified. The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) which is determined using Inspection Manual Chapter (IMC) 2519, Construction Significance Determination Process.

Cross-cutting aspects are determined using IMC 0613, Appendix F, Construction Cross-Cutting Areas and Aspects. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy. The NRCs program for overseeing the safe construction of commercial nuclear power reactors is described in IMC 2506, Construction Reactor Oversight Process General Guidance and Basis Document.

A. NRC-Identified and Self Revealed Findings (Green) The inspectors identified a construction finding of very low safety significance with an associated NCV of Title 10 of the Code of Federal Regulations Part 50 (10 CFR 50), Appendix B, Criterion III, "Design Control" for the licensee's failure to have design control measures for the 18-inch diameter carbon steel guard pipes for containment vessel penetrations P44 and P45. Specifically, the site previously performed a structural analysis that omitted the guard pipe portion of the penetrations and did not consider how the guard pipe exclusion would infringe upon the design margin for ensuring the requirement for American Society of Mechanical Engineers (ASME) Code Section III, Level C service limits were not exceeded, in accordance with the current licensing basis. The Licensee entered this issue into its corrective action program (CAP) as condition report (CR) 50053621 and updated its structural model calculations as part of the corrective action.

The performance deficiency was of more than minor safety significance, and thus a finding, because it represented an adverse condition that rendered the quality of a structure, system, and component (SSC), unacceptable or indeterminate, and required substantive corrective action. This finding was not associated with an inspection, test, analyses, and acceptance criteria (ITAAC); it was not associated with a security program; it was not associated with an IMC 2504 operational/construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. This finding was of very low safety significance because the licensee was able to demonstrate the design function of the applicable structure or system (containment vessel) would not be impaired by the deficiency by successfully reperforming a structural model calculation. The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect Documentation, in the area of Human Performance, in accordance with IMC 0613, Appendix F, Construction Cross-Cutting Areas and Aspects. Specifically, the licensee did not ensure its calculations were reflective of the ASME Level C service limit requirements for the P44 and P45 penetration guard pipes. [H.7] (Section 1A08) 2

(Green) The inspectors identified an ITAAC finding of very low safety significance with an associated NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings. The licensee failed to construct and perform quality inspections on Unit 3 and Unit 4 Class 1E DC and uninterruptible power supply system (IDS) battery racks for the 250 Vdc 24-hour, 72-hour, and spare batteries in accordance with ITAAC 2.6.03.02.i and the approved design requirements for Vogtle Units 3 and 4. The licensee entered this finding into its CAP as CR 50066999, conducted engineering analysis of the nonconforming conditions, and performed rework on the battery racks to correct the nonconforming conditions.

This performance deficiency was of more than minor safety significance, and thus a finding, because it was material to the acceptance criteria of an ITAAC and invalidated the Inspection, Test, or Analyses described in the ITAAC 2.6.03.02.i. This finding was not associated with a security program; it was not associated with an IMC 2504 operational or construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. This finding was a licensee performance deficiency of very low safety significance because it was associated with the IDS and there was reasonable assurance the design function of the system would not have been impaired by the deficiency based on engineering analysis of the nonconforming conditions identified. The inspectors determined this finding was indicative of present licensee performance and affected the cross-cutting area of human performance and the cross-cutting aspect of avoiding complacency. The proximate cause of the performance deficiency was primarily attributed to a failure to perform a thorough review of the work instructions and to plan the activity every time without relying on past successes and assumed conditions. [H.12] (Section 1A15)

B. Licensee-Identified Violations None 3

REPORT DETAILS Summary of Plant Construction Status Unit 3: The licensee completed shield building construction and was in the process of finalizing the as-built design. In the containment building, the licensee satisfactorily performed the American Society of Mechanical Engineers (ASME) required hydrostatic test on the reactor and reactor coolant systems. In the containment and auxiliary buildings, the licensee continued with installation of safety related instrumentation, electrical conduits and cables (safety and non-safety related), necessary to support hot functional testing. In the turbine building, the licensee established main condenser vacuum and placed the main turbine on the turning gear for the first time. The licensee received the first shipment of nuclear fuel at the site.

Unit 4: The licensee completed the shield building tension ring and set the conical roof. In the containment building, the licensee continued with installation of reactor coolant system (RCS) and passive core cooling system (PXS) small bore piping and was in the process of routing electrical raceways, cables, and terminations. In the auxiliary building, the licensee continued with construction of the building up to elevation 180-feet and continued with installation of electrical cabinets, raceways, conduits and cables (safety and non-safety related).

7

The inspectors reviewed the work package for the piping and components associated with ASME Code Section III hydrostatic test procedure 3-RCS-ITPP-503, Reactor Coolant System Cold Hydrostatic Test - Preoperational Test Procedure. The inspectors reviewed the work package instructions and the licensee's procedure for construction pressure testing to determine whether the following test attributes were included:

• the system boundary included all pressure vessels, piping, pumps, and valves that were part of the piping system to be tested;

• the system was vented during the filling operation;

• water quality was specified as required by the latest licensee approved specifications for the temperatures to be present during the test;

• temperature requirements were stated to ensure components were maintained above the nil-ductility transition temperature during hydrostatic pressure testing;

• minimum hydrostatic test pressure was as specified in the applicable design and/or fabrication specification; maximum hydrostatic test pressure was less than the limits in the applicable design and/or fabrication specification; and

• hydrostatic test pressure was maintained for a minimum of 10 minutes before initiation of the examination for leakage; and

• examination for leakage included all joints, connections, and regions of high stress, such as openings, attachments, and thickness transition sections at a pressure equal to the design pressure or three-fourths of the test pressure, whichever was greater.

The inspectors conducted walkdowns prior to the test to verify valve positions and system boundaries were set up in accordance with the system boundary maps within the work package. The inspectors also verified the fill points and vent points were set up in accordance with the work package.

The inspectors observed the ASME Code Section III hydrostatic test to determine if the testing was conducted in accordance with the requirements of ASME Section III, Subsection NB-6000, the work package instructions, and the licensee's procedure 3-RCS-ITPP-503 for construction pressure testing. Specifically, the inspectors observed the test to determine if:

• the latest revision of the test procedure was available and used;

• test prerequisites were met;

• joints, including welded joints, were left uninsulated and exposed for examination during the tests;

• valve lineup/system checklists were completed;

• water quality and temperature were as stated in the procedures;

• calibrated pressure gauges of the required range were installed where required;

• calibrated relief valves of the required set point and capacity were installed where required;

• testing was performed as required by the approved procedure;

• crew actions were correct and timely during the performance of the test and coordination existed among crew members to conduct the test; 8

• temporary modifications such as jumpers, strainers, spool pieces, or blank flanges were installed and tracked per established administrative controls; and

• overall test acceptance criteria were satisfied.

The inspectors also reviewed the results from the 3-RCS-ITPP-503 procedure for ASME Code Section III hydrostatic test to determine if the results conformed to the requirements of ASME Code Section III, Subsection NB-6000. Specifically, the inspectors reviewed the test results to determine if they were identifiable and retrievable evidence of activities affecting quality and were reviewed and verified to be complete per the licensees procedures.

b. Findings No findings were identified.

1A05 (Unit 3) ITAAC Number 2.1.02.12a.i (53) / Family 07E

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.1.02.12a.i (53). The inspectors used the following NRC IPs/sections to perform this inspection:

• 65001.07-02.03 - Post Installation Activities

• 65001.E-02.04-Documentation The inspectors reviewed the equipment qualification reconciliation reports (EQRRs) for ADS motor-operated valves (MOV) RCS-PL-V001B, RCS-PL-V003A, and RCS-PL-V013B to determine whether the licensee assessed work packages, design changes, and nonconformances to verify the as-built configuration, including anchorage, were seismically bounded by the analyzed conditions in accordance with data sheets SV3-PV01-Z0D-131 and SV3-PV01-132 and design specification SV3-PV01-Z0-001.

The inspectors reviewed the licensee's methodology and selection of applicable work orders, data sheets, and design drawings, to determine whether the inspections and analyses demonstrated the as-built installed ADS MOVs were bounded by tests or type tests. The inspectors reviewed the equipment qualification summary reports (EQSRs) and equipment qualification data packages (EQDPs) to determine whether installation restrictions were translated, via the design process, to the drawings and EQRRs. The inspectors performed a review of as-installed electrical connections to determine whether the electrical connections were installed as tested so the valves would function during a design basis accident.

The inspector performed a walkdown of the ADS valve area (room 11603) and verified the as-built configuration of two second-stage ADS A & B MOVs, RCS-PL-V002A and RCS-PL-V002B, matched the analyzed configuration.

9

The inspectors also interviewed licensing personnel to determine how inspection and analysis were performed for applicable nonconformances and engineering and design coordination reports (E&DCRs) issued during fabrication, handling, installation, and testing to verify all deviations were bounded by the seismically analyzed conditions.

b. Findings No findings were identified.

1A07 (Unit 3) ITAAC Number 2.1.03.13 (88) / Family 05F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.1.03.13 (88). The inspectors used the following NRC IPs/sections to perform this inspection:

• 65001.05 - Inspection of ITAAC-Related Installation of Reactor Pressure Vessel and Internals

• 65001.05-02.01 - Purchase and Receipt of Components

• 65001.F- Inspection of the ITAAC-Related Design and Fabrication Requirements

• 65001.F-02.02-Fabrication Records Review The inspectors performed an inspection to verify a report exists and concludes the fuel assemblies and rod cluster control assemblies (RCCA) intended for the initial core load and listed in Table 2.1.3-1 of Appendix C to the Vogtle Unit 3 COL, had been designed and constructed in accordance with the principal design requirements.

The inspectors reviewed APP-SSAR-F5-001, AP1000 Safety Analysis Checklist, Revision 1, which is specific to the Vogtle 3 first core design and additional changes made to the AP1000 fuel assembly, RCCA, and gray rod control assembly designs.

The inspectors reviewed the safety analysis checklist to verify if the first core safety analysis performed by Westinghouse for Cycle 1 met the principal design requirements listed in the UFSAR Section 4.1.1, and more broadly the UFSAR Chapter 4 requirements.

The inspectors also reviewed the Unit 3 Cycle 1 Core Operating Limits Report (COLR), which is specific to the Vogtle 3 Cycle 1 core design and provides the applicable core operating limits of the safety analysis (e.g., fuel thermal mechanical limits, core thermal hydraulic limits, PXS limits, nuclear limits such as shutdown margin, transient analysis limits, and accident analysis limits). The inspectors reviewed the COLR to verify if the core operating limit results were consistent with those in the Safety Analysis Checklist and the UFSAR Chapter 4 requirements.

The inspectors reviewed selected quality records including the Unit 3 Cycle 1 Core Loading Plan and the letter documenting the verification and certification of the fuel assemblies and RCCA from the vendor to verify the components conformed with the design requirements.

b. Findings No findings were identified.

1A08 (Unit 3) ITAAC Number 2.2.01.02a (91) / Family 06F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.01.02a (91). The inspectors used the following NRC IPs/sections to perform this inspection:

• 65001.11-02.11 - Problem Identification and Resolution The inspectors reviewed the licensees corrective actions to address unresolved item (URI)05200025/2020003-02, ASME Section III Level C service Limits May Not Be Met for Containment Penetrations P44 and P45," which were captured in the corrective action program (CAP) as condition report (CR) 50063621 and Westinghouse Electric Company (WEC) CAP as issue report (IR) 2020-10571. The inspectors also reviewed E&DCR APP-ML10-GEF-046 (with attached APP-ML10-S3C-001 calculations) and finite element analysis (FEA) model files for containment penetration P44 and P45 guard pipes referenced in the E&DCR to verify loadings associated with the Vogtle Unit 3 containment design pressure and temperatures in combinations with a safe shutdown earthquake can be extracted from the model. The inspectors reviewed the results from the FEA model files against the Level C service limits of the ASME Code,Section III, Paragraph NE-3221.

The inspectors also reviewed proposed changes to the licensees calculation APP-ML10-S3C-001, AP1000 Containment Piping Penetrations with Flued Heads Analysis and Verification, to determine if the contents of the analysis included the penetration guard pipes and demonstrated the acceptance criteria of ITAAC 2.2.01.02a for Unit 3 was not impacted.

Based on the inspectors review, URI 05200025/2020003-02 is closed and NCV 05200025/2020004-01 is opened and closed in this report.

b. Findings Introduction The inspectors identified a construction finding of very low safety significance (Green) with an non-cited violation (NCV) of Title 10 of the Code of Federal Regulations Part 50 (10 CFR 50), Appendix B, Criterion III, "Design Control," for the licensees failure to have design control measures for the 18-inch diameter carbon steel guard pipes for containment vessel penetrations P44 and P45. Specifically, the site previously performed a structural analysis that omitted the guard pipe portion of the penetrations and did not consider how the guard pipe exclusion would infringe upon the design margin for ensuring the requirement for ASME Section III, Level C service limits were not exceeded, in accordance with the current licensing basis.

Description In NRC inspection report 05200025/2020003, the inspectors opened URI 05200025/2020003-02, ASME Section III Level C service Limits May Not Be Met for Containment Penetrations P44 and P45" because the licensee had not performed an analysis for the guard pipes for penetrations P44 and P45, as required by the UFSAR, Revision 9.0, Subsection 3.6.2.1.1.4. The licensee entered this issue into its CAP as 50053621. The issue remained unresolved pending further analysis by the licensee and Westinghouse.

The Vogtle Unit 3 containment penetration P44 and P45 guard pipes are in the break exclusion area in the annulus region between the containment vessel and shield building (SB). The guard pipes internally contain the 6-inch diameter startup feedwater pipes that are routed from the turbine building through the auxiliary building to the corresponding steam generators. Subsection 3.6.2.1.1.4 of the Vogtle 3 and 4 UFSAR, High Energy Piping in Containment Penetration Areas, states, in part, that breaks are not postulated in the portions of ASME Code,Section III piping, defined as break exclusion piping, provided it meets the provision(s) that Level C service limits of ASME Code,Section III, Paragraph NE-3221 are not exceeded by the loadings associated with containment design pressure and temperature in combinations with a safe shutdown earthquake. However, the licensees structural and thermal analysis model omitted the guard pipe portion of the penetrations and did not consider how this exclusion might infringe upon the design margin for ensuring the requirement for ASME Section III, Level C service limits were not exceeded. The licensee documented this issue in its CAP as CR 50063621 and WEC CAP IR-2020-10571.

The inspectors reviewed the changes to the calculation addressed in E&DCR APP-ML10-GEF-046, Update for Penetrations 44 and 45, that included calculation APP-ML10-S3C-001, AP1000 Containment Piping Penetrations with Flued Heads Analysis and Verification, to determine if the contents of the analysis showed that UFSAR Subsection 3.6.2.1.1.4 criteria were met and the acceptance criteria of ITAAC 2.2.01.02a was not impacted. Specifically, the inspectors reviewed the structural model calculation to verify contents were in accordance with ASME Code Section III, Subsection NE design criteria described in Article NE-3000 for Class MC metal containment components. The inspectors reviewed the penetration design analysis against the requirements in ASME Section III requirements of subparagraphs NE-3221.1, General Primary Membrane Stress Intensity and NE-3221.4, Primary Plus Secondary Stress Intensity.

The inspectors evaluated the primary stress loading analysis results for the guard pipes associated with the containment design pressure and temperature in combination with a safe shutdown earthquake to verify the results did not exceed the Level C service limits of the ASME Code Section III, Paragraph NE-3221. Based on their review, the inspectors determined the information provided in the E&DCR provided reasonable assurance that containment penetrations P44 and P45 met the licensing requirement of the Vogtle UFSAR, Revision 9.0, Subsection 3.6.2.1.1.4.

14

Analysis The inspectors determined the licensees failure to have design control measures for the 18-inch diameter carbon steel guard pipes for containment vessel penetrations P44 and P45 was a performance deficiency. The inspectors determined that the failure to ensure Level C service limits were not exceeded by the design loading conditions with a safe shutdown earthquake, as required in the licensing basis was contrary to the requirements of 10 CFR 50, Appendix B, Criterion III, Design Control, and resulted in a performance deficiency that required substantive corrective action.

Per the guidance in IMC 0613, Power Reactor Construction Inspection Reports, Appendix B, Issue Screening, dated November 4, 2020, the inspectors determined traditional enforcement or enforcement discretion would not apply to this performance deficiency. Per IMC 0613, Appendix E, Examples of Minor Construction Issues, dated November 4, 2020, the inspectors determined this performance deficiency was of more-than-minor safety significance, and thus a finding, because it represented an adverse condition that rendered the quality of an SSC unacceptable or indeterminate, and required substantive corrective action.

The inspectors determined this finding was related to the Design/Engineering cornerstone of the Construction Reactor Safety strategic performance area. This was a construction finding and it was not associated with an inspection, test, analyses, and acceptance criteria. This finding was not associated with a security program; it was not associated with an IMC 2504 operational/construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute.

The inspectors assessed the finding using IMC 2519, Appendix A, AP1000 Significance Determination Process, dated October 26, 2020, and determined the finding was a performance deficiency of very low safety significance (Green) because it was associated with the containment system (CNS), a structure assigned to the intermediate risk column of the AP1000 Construction Significance Determination Matrix. The inspectors determined this finding was a finding of very low safety significance because the licensee was able to demonstrate the design function of the applicable structure or system (containment vessel) would not be impaired by the deficiency by successfully reperforming a structural model calculation.

The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Documentation in the area of Human Performance, in accordance with IMC 0613, Appendix F, Construction Cross-Cutting Areas and Aspects, dated November 4, 2020. The licensee did not ensure its calculations were reflective of the ASME Level C service limit requirements for the P44 and P45 penetration guard pipes. [H.7].

15

Enforcement 10 CFR 50, Appendix B, Criterion III, Design Control, requires, in part, that design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews to items such as stress, thermal, and accident analyses. UFSAR Section 3.6.2.1.1.4, High Energy Piping in Containment Penetration Areas, states, in part, that breaks are not postulated in the portions of ASME Code,Section III, Class 2 or Class 3 piping, as break exclusion piping, provided the subject piping that meets the provisions to support the UFSAR for Level C service limits of ASME Code,Section III, Paragraph NE-3221 are not exceeded by the loadings associated with containment design pressure and temperature in combinations with a safe shutdown earthquake. The licensees postulation was based on ASME Section III Level C service limits not being exceeded.

Contrary to the above, on and before September 23, 2020, the licensee did not have design control measures for verifying or checking the adequacy of design of the 18-inch diameter carbon steel guard pipes for containment vessel penetrations P44 and P45. Specifically, the licensee previously performed a structural analysis that omitted the guard pipe portion of the penetrations and did not consider how the guard pipe exclusion would infringe upon the design margin for ensuring the requirement for ASME Section III, Level C service limits were not exceeded, in accordance with the current licensing basis. The licensee entered this issue into its CAP as CR 50063621 and updated the structural model calculations as part of the corrective action. Because this violation was not repetitive or willful, was of very low safety significance (Green), and was entered into the licensees CAP, it is being treated as an NCV consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2020004-01, Failure to verify ASME Code Section III Level C Service Limits in Accordance with License Basis and ASME Code Section III).

• 65001.F-02.02-Fabrication Records Review Yes

• 65001.F-02.04-General QA Review The inspectors reviewed documentation and conducted walkdowns of protection devices for the EPAs to verify the as-built containment EPAs were protected against currents which are greater than their continuous ratings as required by Appendix C to the Vogtle Unit 3 COL.

Specifically, for cables that originated from medium voltage switchgears, low voltage distribution panels and motor control centers feeding motors inside containment, the inspectors verified that overcurrent protection was provided for the cables. The inspectors reviewed reports and calculations to verify the design addressed protection from currents which were greater than the continuous ratings of the EPA cables.

17

For medium voltage cables, the inspectors reviewed engineering studies that specified the overcurrent protection relay settings using time-current curves of the Schweitzer Engineering Laboratories 710 relays. As shown in the curves, these relays, as programmed, provided adequate level of protection for the cables running through the EPA. For low voltage cables, the inspectors conducted a walkdown of distribution panels and motor control centers to verify the size of fuses used to protect feeders and wiring routed through the EPAs were in accordance with the design.

b. Findings Introduction The inspectors identified an ITAAC finding of very low safety significance (Green) with an associated NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to construct and perform quality inspections on Unit 3 and Unit 4 IDS battery racks for the 250 Vdc 24-hour, 72-hour, and spare batteries in accordance with ITAAC 2.6.03.02.i and the approved design requirements for Vogtle Units 3 and 4.

Description ESR 50053212 was written to evaluate misaligned channel nuts, also known as misaligned spring nuts, on IDS battery racks in Unit 3 room 12102. The term misaligned spring nuts refers to spring or channel nuts that may not be seated on the Unistrut rail channel sections. Thus, the slots within the spring nuts may not be fully engaged with the rails folded edges in accordance with Section 7.3, Install Support Rails & Side Rails to Frame, of Vendor Manual APP-DB01-V8M-001. The licensee had captured this issue in its CAP on June 16, 2020 (ESR 50053212) and closed the issue without completing an evaluation. The Unit 3 IDS battery racks were fully assembled, hardware was torqued, and spring nuts had been QC inspected and accepted during the installation of the battery racks. The IDS batteries were also installed in the racks with cables already terminated.

The inspectors noted step 3010 of work packages SV3-IDS-DBW-860173 and SV3-DS-DBW-860174 required rack installation per vendor manual SV3-DB01-V8M-001. The vendor manual required spring nuts to be seated in accordance with Figure 7.3 d, steps 1 through 4. After a review of the work packages, specifically Section 3.3, the inspectors noted the QC inspection staff had concluded, by initial on the electrical equipment installation inspection records, the equipment and hardware (e.g. spring bolts and nuts) were mounted correctly.

On July 28, and August 5, 2020, responding to the NRCs follow-up questions on the condition of misaligned spring nuts, the licensee initiated CR 50057411 and CR 50058215 respectively, that identified multiple instances where the grooves in the vendor supplied spring nuts were not seated in the Unistrut channel sections of several IDS battery racks (i.e., SV3-IDSC-DB-1A, SV3-IDSC-DB-1B and SV3-IDSS-DB-1A) in rooms 12102 and 12103. The spring nuts were already QC inspected and accepted during the installation of the battery racks. In addition, ESR 50057274 was also initiated to determine if this as-built condition was adequate, as originally intended by ESR 50053212.

In addition, the licensee conducted a QA surveillance from August 5 through November 16, 2020, where additional nonconformances were identified for the batteries, specifically with the as-built condition of the battery racks after QC inspections were previously completed. Specifically, Quality Surveillance 26193-000-GQA-QSSS-20160 of the Unit 3 battery racks as-built configuration was performed to verify compliance with vendor instructions and project specifications. This quality surveillance identified several cross bracings were not installed per the manufacturers instructions in rooms 12102 and 12202, and CR 50062315 was initiated to address this issue.

As a result of the extent of condition performed, the licensee initiated CR 50062981 that identified the battery racks vendor was not consulted to determine whether material hardware substitution (i.e., bolts, washers and nuts) met the quality requirements under its commercial dedication program. Specifically, nonconformance and disposition (N&D) SV3-IDSB-GNR-000002 allowed use of a substitute material for rail nuts and related hardware on IDS battery racks for 3-IDSB-DB-2B. The N&D accepted the form, fit, and function of the alternate material as meeting APP-DB01-Z0-001, Design Specification for Class 1E 250 VDC Batteries and Racks for System IDS, Revision 7.

23

However, the vendor was not consulted, and the NRC inspectors noted that material weight differences were not documented as part of the original evaluation for this material substitution.

The licensees extent of condition inspection identified additional safety related spring nuts not seated, as required in vendor manuals Figure 7.3d, steps 1 through 4. This nonconforming condition was found in all the IDS battery racks from both Unit 3 and Unit 4, thus potentially affecting the safety function of all the 250 Vdc 24-hour, 72-hour, and spare batteries. Further, the spring nuts in Unit 3 rooms 12101, 12102, 12103, 12104, 12105, 12202 and 12204 had already been QC inspected and accepted during the installation of the battery racks. These issues were captured in the CAP as CRs 50057411, 50058215, and 50054000.

Due to the cumulative effects of multiple nonconforming issues, it was indeterminate if the applicable Category 1 equipment could withstand seismic design basis loads without a loss of safety function and if the as-built equipment, including anchorage, was seismically bounded by the tested or analyzed conditions. The licensee entered all these issues into its CAP as CR 50066999. Investigation and resolution of several of these issues were addressed under the scope of ESR 50057274. The licensee completed evaluations SVP-SV0-006012, Battery Rack Nonconformance Structural Safety Evaluation and SVP-SV0-006099, Battery Rack Nonconformance Structural Safety Evaluation - Updated Based on Completed Extent of Condition Work, that demonstrated there was reasonable assurance that the design function of the system would not have been impaired by the deficiency based on engineering analysis of the nonconforming conditions identified. The licensee also restored the Unit 3 and 4s as-built configuration of the IDS battery racks to match the seismically qualified condition as specified by the design.

Analysis The inspectors determined the licensees failure to construct and perform quality inspections on battery racks for the Unit 3 and Unit 4 IDS 24-hour, 72-hour, and spare batteries in accordance with ITAAC 2.6.03.02.i and the approved design requirements for Vogtle Units 3 and 4 was a performance deficiency. The inspectors determined that the failure to meet the requirements in SV3-DB01-V8M-001 and APP-DB01-Z0-001 was contrary to the requirements of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, and resulted in a performance deficiency that required substantive corrective action. Per the guidance in IMC 0613, Power Reactor Construction Inspection Reports, Appendix B, Issue Screening, dated November 4, 2020, the inspectors determined traditional enforcement or enforcement discretion would not apply to this performance deficiency.

Per further guidance in IMC 0613, Appendix E, Examples of Minor Construction Issues, dated November 4, 2020, the inspectors determined this performance deficiency was of more than minor safety significance, and thus a finding, because it was material to the acceptance criteria of an ITAAC and invalidated the Inspection, Test, or Analysis described in the ITAAC. Specifically, the design commitment for ITAAC 2.6.03.02.i (Sequence 597) is the seismic Category I equipment identified in Table 2.6.3-1 can withstand seismic design basis loads without loss of safety function.

Table 2.6.3-1 lists IDS 250 Vdc 24-hour, 72-hour, and spare batteries as applicable seismic Category I equipment.

24

The acceptance criteria for this ITAAC states in part that a report exists and concludes that the as-built equipment including the anchorage is seismically bounded by the tested or analyzed conditions. The inspectors determined that the performance deficiency was material to ITAAC 2.6.03.02.i because the cumulative effects for the multiple non-conformances with the as-built seismic Category I IDS equipment, after QC inspections were completed and deemed acceptable, it was indeterminate if the applicable Category 1 equipment could withstand seismic design basis loads without a loss of safety function and if the as-built equipment, including anchorage, was seismically bounded by the tested or analyzed conditions.

The inspectors determined this finding was related to the Construction/Installation cornerstone of the Construction Reactor Safety strategic performance area. The inspectors determined this finding was not associated with a security program; it was not associated with an IMC 2504 operational/construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. In accordance with IMC 2519, Construction Significance Determination Process, Appendix A, AP 1000 Construction Significance Determination Process, dated October 26, 2020, the inspectors determined this finding was a performance deficiency of very low safety significance (Green) because the licensee was able to demonstrate with reasonable assurance the design function of the structure or system would not be impaired by the deficiency, and the nonconforming conditions were corrected such that the installation was seismically bounded by the tested or analyzed conditions. Under the AP 1000 Construction Significance Determination Matrix in Attachment A of IMC 2519, the IDS is classified as a High Safety System under the System/Structure Risk Column and the finding concerned the same design and safety functions of multiple trains or the entire IDS battery system as listed in AP 1000 System Design Function Definitions and the COL. Based upon the NRC review of the licensees evaluations SVP-SV0-006012 and SVP-SV0-006099 that demonstrated there was reasonable assurance the design function of the system would not have been impaired by the deficiency, the inspectors determined the performance deficiency would not impair the design function of the IDS, therefore the finding screened for Row 1 under Table Construction Significance Determination Process Matrix Quality of Construction Y -

Axis Flow Diagram.

The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Avoiding Complacency in the area of Human Performance, in accordance with IMC 0613, Appendix F, Construction Cross-Cutting Areas and Aspects, dated November 4, 2020. The proximate cause of the performance deficiency was attributed to a failure to use human error reduction techniques, namely a failure to perform a thorough review of the work instructions and to plan the activity every time without relying on past successes and assumed conditions. [H.12]

Enforcement 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings.

25

Contrary to the above, on and before August 5, 2020, the licensee failed to install battery racks for the Unit 3 and Unit 4 250 Vdc 24-hour, 72-hour, and spare IDS batteries in accordance with ITAAC 2.6.03.02.i and the approved design requirements specified in SV3-DB01-V8M-001 and APP-DB01-Z0-001. The licensee entered this finding into its CAP for evaluation and identification of appropriate corrective actions (CR 50066999). Corrective actions were completed for this issue, which included rework on the battery racks to correct the nonconforming conditions in both units.

Because this violation was not repetitive or willful; was of very low safety significance; and was entered into the licensees CAP, it is being treated as an NCV consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2020004-02 and 05200026/2020004-02, Failure to Construct and Perform Quality Inspections on the Battery Racks for the Class 1E DC and Uninterruptible Power Supply System).
