SUMMARY

OF FINDINGS Inspection Report (IR) 05200025/2022001, 05200026/2022001; 01/01/2022 through 03/31/2022; Vogtle Units 3 and 4 Combined License, Integrated Inspection Report.

This report covers a three-month period of inspection by regional and resident inspectors. Two Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) findings of very low safety significance (Green) with associated non-cited violations (NCVs) and one construction finding of very low safety significance (Green) with an associated NCV 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 an ITAAC 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. The licensees failure to assure the Unit 3 Class 1E dc and uninterruptible power supply system (IDS) 24-hour, 72-hour, and spare safety-related battery racks were installed in accordance with ITAAC 2.6.03.02.i (597) and the approved design was a performance deficiency (PD). The licensee entered this finding into its corrective action program (CAP) as condition report (CR) 50130395 for evaluation and identification of corrective actions.

As immediate corrective actions, the licensee restored the as-built configuration of the Unit 3 IDS battery racks to match the seismically qualified condition specified by the design.

This PD 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, with the nonconforming conditions the IDS batteries did not meet the acceptance criteria. The finding was of very low (Green) safety significance because the licensee was able to demonstrate with reasonable assurance through additional analyses that the design function of the Class 1E IDS batteries would not be impaired by the PD, and the nonconforming conditions were corrected such that the installation is seismically bounded by the tested or analyzed conditions. The finding was indicative of current licensee performance and was associated with the cross-cutting area of Human Performance and the cross-cutting aspect of Procedure Adherence. The proximate cause of the PD was attributed to a failure to review procedures and instructions before work was performed to validate they were appropriate for the scope of work and required changes were completed before implementation.

[H.8] (Section 1A09)

(Green) The inspectors identified an ITAAC finding of very low safety significance with an associated NCV of 10 CFR 52.99(c)(1), ITAAC Closure Notification, for the licensees failure to submit an ITAAC closure notification (ICN) for Unit 3 ITAAC 3.3.00.02a.i.b (761) that contained sufficient information to demonstrate the prescribed inspections, tests, and analyses had been performed and the prescribed acceptance criteria were met and was a PD. As immediate 2

corrective actions, the licensee withdrew the ICN. Subsequently, the licensee completed an engineering evaluation to address areas of the shield building concrete wall with thickness not meeting the requirements of the Vogtle 3 and 4 Updated Final Safety Analysis Report Table 3.3-1 and the as-built summary report for the shield building was updated to reflect the closure of the associated nonconformance and disposition report (N&D). The licensee entered this finding into its CAP for evaluation and identification of corrective actions as CR 50127060.

The PD was of more than minor safety significance and an ITAAC finding because it represented a substantive failure to implement a program, process, procedure, or quality oversight function that was material to the acceptance criteria of an ITAAC. Specifically, the licensee failed to develop an ICN that accurately reflected ITAAC completion as supported by verifiable documents and traceable records. As a result, the ICN would have been rejected by the NRC, if it had not been withdrawn voluntarily. The PD was material to the acceptance criteria of an ITAAC since it was associated with deviations that had not been repaired or reconciled to the approved design as required by the ITAAC. Based on review of N&D SV3-CC01-GNR-000686, the inspectors determined the design function of the affected structure would not have been impaired by the deficiency. As a result, the inspectors concluded the finding was of very low safety significance (Green). The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Conservative Bias in the area of Human Performance. The proximate cause of the PD was attributed to the failure to use conservative decision making when submitting the ICN without having all the determination basis input documents finalized. [H.14] (Section 1A10)

(Green) The inspectors identified a construction finding of very low safety significance with an associated NCV of 10 CFR 50, Appendix B, Criterion III, Design Control, for the licensees failure to assure applicable regulatory requirements and the design basis, as defined in § 50.2 and as specified in the license application, for those structures, systems, and components (SSCs) to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions. Specifically, the licensees failure to evaluate applicable design inputs in the design package (E&DCR APP-GW-GEF-2640) that installed EMC glands in Class 1E plant electrical enclosures was a PD. The licensee entered this finding into its CAP for evaluation and identification of appropriate corrective actions as CR 50125873. As immediate corrective actions, the licensee issued new E&DCRs APP-GW-GEF-519 and APP-GW-GEF-529 that analyzed, and provided seismic testing results, indicating the seismic input for the EMC glands met the as-built seismic Category II, Class D component and would not adversely affect the ability of plant Class 1E electrical enclosures to perform their intended safety function during a seismic event.

The PD was of more than minor safety significance, and thus a finding, because it represented a substantive non-conservative error in a design document that defines the technical requirements for plant Class 1E electrical enclosures and justification was required by the licensee to ensure the as-built seismic Category II, Class D component did not adversely affect the ability of plant Class 1E electrical enclosures to perform their intended safety function during a seismic event. The inspectors determined the finding was not material to an ITAAC and therefore it was a construction finding because the EMC gland seismic qualifications did not impact the seismic qualifications and acceptance criteria of ITAAC related 1E panels in which the glands were installed. The finding was of very low safety significance (Green) because the licensee subsequently revised the design documents to include seismic evaluation and testing results that determined the EMC glands would not affect seismic Category I SSCs during a seismic event. The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Change Management in the 3

area of Human Performance. The proximate cause of the PD was attributed to the licensees failure to implement a process where managers maintain a clear focus on nuclear safety when implementing the change management process to ensure significant unintended consequences are avoided. [H.3] (Section 1P02)

B. Licensee-Identified Violations None.

REPORT DETAILS Summary of Plant Construction Status Unit 3: The licensee has completed the majority of plant construction and was finalizing the as-built design. The licensee performed post work verification on safety-related (SR) and nonsafety-related (NSR) structures, systems, and components (SSCs) as it completes repair and remediation of electrical systems. Class 1E dc and uninterruptible power supply system (IDS), main alternating current electrical distribution system, and standby onsite power system testing was performed to verify the functional capability of those systems to support electrical loads during normal and off-normal conditions. Additionally, preoperational testing of the protection and safety monitoring system (PMS) and IDS was in progress after component testing to demonstrate the equipment and systems performed in accordance with the design criteria.

Unit 4: The licensee completed the majority of civil and mechanical construction for the nuclear island and continued installation of small-bore piping in plant fluid systems. The licensee continued installation of plant electrical cabinets, raceways, conduits, and cables. The licensee continued integrated flush activities by flushing portions of chemical volume and control (CVS),

spent fuel pool cooling, reactor coolant (RCS), residual heat removal (RNS), and passive core cooling (PXS) systems. The licensee continued open vessel testing activities, which included taking a suction from the spent fuel pool and cask loading pit and discharging to the reactor vessel through the direct vessel injection line. The American Society of Mechanical Engineers (ASME) pneumatic pressure test and the integrated leak rate test were completed to verify the ability of the containment system to perform its SR function of providing containment integrity as a barrier against the release of fission products to the atmosphere.

The inspectors reviewed the contents of the final system SV3-RCS-MUR-001 and supporting ASME N-5 code data reports that included components, items, and supports to verify entries were completed with certification signatures by the certificate holder representative and authorized nuclear inspector (ANI) in accordance with the applicable requirements of ASME NCA-3350 and NCA-8000.

The inspectors reviewed the as-built design reports for a sample of RCS piping to verify the reports addressed functional capability and leak before break (LBB) requirements.

Specifically, the review was performed to determine if the reports concluded the as-built lines met the requirements for functional capability; and the LBB acceptance criteria were met by the as-built piping and piping materials, or a pipe break evaluation report existed and concluded protection from the dynamic effects of a line break was provided.

Portions of the following piping lines were considered in the review: ADS inlet headers, pressurizer surge line, and RCS hot legs.

The inspectors reviewed appropriate sections of the piping analysis reports for portions of the lines listed above to verify the functional capability and LBB requirements were met, and the evaluations were consistent with the Vogtle 3 and 4 Updated Final Safety Analysis Report (UFSAR) Section 3.9.3.1.5 and Appendix 3B, respectively. Specifically, the inspectors reviewed the following tables to verify the functional capability requirements of the Vogtle 3 and 4 UFSAR Table 3.9-11 were met: Tables 2.1-9, 2.1-6, and 2-3 of the piping analysis for the ADS inlet headers, pressurizer surge line, and RCS hot legs, respectively. The inspectors also reviewed the following figures to verify the points corresponding to the actual normal and maximum stresses for the governing load combinations at the critical locations for the LBB evaluations were enveloped by the bounding analysis curves: Figure A.21-3 of the piping analysis for the ADS inlet headers, Figures A.20-1 and A.20-2 of the piping analysis for the pressurizer surge line, and Figure 5-3 of the piping analysis for the RCS hot legs.

8

Additionally, the inspectors verified the as-built design reports, for the piping lines listed above, reconciled deviations between the documents used for construction and the corresponding documents used for the design analysis, as required by ASME Section III NCA-3554. Specifically, the inspectors verified any impacts to the functional capability or LBB analyses were appropriately evaluated and reconciled.

b. Findings No findings were identified.

In addition, the inspectors reviewed EQRR for the PCS SR containment pressure sensors SV3-PCS-07 and SV3-PCS-013 to determine whether the licensee assessed work packages, design changes, and nonconformances to confirm the as-built configuration, including anchorage, were seismically bounded by as-tested conditions in accordance with the applicable data sheets and design specifications, and satisfy the seismic Category 1 and harsh environment acceptance criteria contained in ITAAC 2.2.02.05a.i.

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 installed components were bounded by the design characteristics that were documented in the analyses. The inspectors reviewed the equipment qualification summary reports and equipment qualification data packages to determine whether installation restrictions from testing were translated to the drawings and EQRRs. The inspectors performed a walkdown of the installed components to confirm the satisfactory installation of the Class 1E sensors and associated wiring, cables, and terminations that were qualified for either seismic or seismic and harsh environment was bounded by the type tests, analyses, or combination of type tests and analyses. The inspectors performed a review of as-installed electrical connections to determine whether the electrical connections were installed as-tested so the isolation valves would function during a design basis accident. The inspectors also verified the mechanical anchorage was bounded by the tested conditions.

The inspectors verified each sensor and valve manufacturer make/model/serial number, location, and mounting orientation were per the design drawings. The inspectors reviewed the work packages and confirmed the torque values applied were per the required design drawing and the torque wrenches used were within their calibration cycle.

The inspectors also interviewed licensing personnel to determine how inspection and 13

analyses were performed for applicable nonconformances and E&DCRs issued during fabrication, handling, installation, and testing to verify deviations were bounded by the seismically analyzed conditions.

b. Findings No findings were identified.

1A06 (Unit 3) ITAAC Number 2.2.02.07b.i (138) / Family 06D

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.02.07b.i (138). The inspectors used the following NRC IP/section to perform this inspection:

65001.06-02.01 - General Installation The inspectors reviewed SV3-PCS-ITR-801138, "Unit 3 Passive Containment Cooling System (PCS) Inspection Coatings: ITAAC 2.2.02.07b.i (Item 7.b.ii and iii)," Revision 0, to verify the inside and outside surfaces of the containment vessel above the operating deck (135 feet (') -3 inches (")) were coated with an inorganic zinc material as specified in Table 2.2.2-3 of Appendix C of the Vogtle Unit 3 Combined License (COL). The inspectors reviewed the inspection test report to determine if coating records concluded the as-applied coatings to the interior surfaces of the containment vessel above the operating deck and the exterior surface of the containment vessel above elevation 135-3 were coated with a SR inorganic zinc coating. The inspectors also reviewed coating repair records to verify the correct material was used and the dry film thickness of the repaired areas were in accordance with the design specification for protective coatings used in the AP1000 plant. The inspectors reviewed the inspection test report to determine if the methyl ethyl ketone test was satisfactorily performed as required for Containment Service Level I (interior) and Service Level III (exterior) surfaces.

b. Findings No findings were identified.

1A07 (Unit 3) ITAAC Number 2.2.03.02a (159) / Family 06F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.03.02a (159). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.03 - Inspection of ITAAC-Related Installation of Piping 65001.03-02.08 - Problem Identification and Resolution 65001.F- Inspection of the ITAAC-Related Design and Fabrication Requirements 65001.F-02.01-Design Document Review 14

The inspectors reviewed the PXS as-built design report and associated ASME N-5 installation code data reports to verify the PXS and the following components were designed, fabricated, constructed, examined, and tested in accordance with design specifications, engineering drawings, and code requirements of the 1998 Edition with Addenda up to and including 2000 Edition of the ASME Section III, Division 1, Subsections NCA for general requirements, NB for Class 1 components, and NF for supports:

Major components within the PXS pressure boundary included, but were not limited to:

o PXS-ME-01, passive residual heat removal heat exchanger; o PXS-MT-01A and B, accumulator tanks; o PXS-MT-02A and B, core makeup tanks; and o PXS-MW-01A and B, ADS spargers.

valves within the PV01, PV02, PV03, PV13, PV20, and PV70 valve commodities; thermowells for resistance temperature detectors; pressure-retaining piping and tubing subassemblies; instruments and instrument manifolds; standard piping penetrations within portions of the piping system; and items, components, and attachments within code jurisdictional boundaries of piping-to-piping and piping-to-supports (in-line fittings, flanges, valves, nozzle and branch connections, and fasteners).

The inspectors reviewed certified as-built design report SV3-PXS-S3R-001 to verify contents were in accordance with the requirements of ASME NCA-3260 using reference supporting calculations for the design, service, and test loading conditions for jurisdictional pressure boundaries highlighted on piping and instrumentation diagrams (P&IDs) APP-PXS-M6-001 and -002.

The inspectors verified reconciliation of design output and input documents for design changes and nonconformances or deviations requiring modifications (including use of Code Cases) were addressed in accordance with the applicable requirements of ASME NCA-3260 and NCA-3500.

The inspectors reviewed the preservice inspection program plan SV3-GW-GEI-100 to verify the following examinations were completed prior to initial plant startup for a selected number of items and components of the PXS:

VT-1 visual examinations for detection of surface discontinuities and VT-3 visual examinations for general mechanical and structural conditions were performed on welded anchor attachments, rigid supports, flange bolting, valve flanges surfaces, nozzle-to-safe ends, and manway studs, nuts, and washers; VT-3 visual examinations for general mechanical and structural conditions were performed on supports for piping and components, valve supports, rigid supports, hydraulic snubbers, and penetration anchors; weld surface PT and volumetric UT were performed on shop and field welds for joining pipes, fittings, valves, flanges, nozzles, branch connections (PT only), and instruments to socket welds (PT only); and augmented volumetric UT were performed on the following field and shop welds 15

to establish a reference baseline of selected circumferential pipe welds to protect against postulated degradation mechanism for LBB analyzed piping:

o SV3-PXS-PLW-013-FW-1 for accumulator tank PXS-MT-01A nozzle N02-to-elbow fitting of 8" diameter; o SV3-PXS-PLW-014-FW-10 for 8" diameter pipe-to-check valve V028A; o SV3-PXS-PLW-023-FW-1 for 8" diameter pipe-to-valve V027B; and o SV3-PXS-PLW-024-SW-5 for 8" diameter pipe-to-swing check valve V028B.

The inspectors reviewed the contents of the final system SV3-PXS-MUR-001 and supporting ASME N-5 code data reports that included components, items, and supports along with system physical nameplate code symbol stampings to verify entries were completed with certification signatures by the certificate holder representative and ANI in accordance with the applicable requirements of ASME NCA-3350 and NCA-8000.

The inspectors reviewed the as-built design reports for a sample of PXS piping to verify the reports addressed functional capability and LBB requirements. Specifically, the review was performed to determine if the reports concluded the as-built lines met the requirements for functional capability; and the LBB acceptance criteria were met by the as-built piping and piping materials, or a pipe break evaluation report existed and concluded protection from the dynamic effects of a line break was provided. Portions of the following piping lines were considered in the review: PRHR inlet line from hot leg, RNS A discharge line to PXS from RNS check valve RNS-PL-V017A to DVI line A, and in-containment refueling water storage tank (IRWST) injection line A to DVI line A.

The inspectors reviewed appropriate sections of the piping analysis reports for portions of the lines listed above to verify the functional capability and LBB requirements were met, and the evaluations were consistent with the Vogtle 3 and 4 UFSAR Section 3.9.3.1.5 and Appendix 3B, respectively. Specifically, the inspectors reviewed the following tables to verify the functional capability requirements of the Vogtle 3 and 4 UFSAR Table 3.9-11 were met: Table 2.1-9 of the piping analysis for portions of the PRHR inlet line from hot leg, and Tables 2.1-2 and 2.1-3 of the piping analyses for portions of the RNS A discharge line to PXS from RNS check valve RNS-PL-V017A to DVI line A, and IRWST injection line A to DVI line A. The inspectors also reviewed the following figures to verify the points corresponding to the actual normal and maximum stresses, for the governing load combinations at the critical locations for the LBB evaluations, were enveloped by the bounding analysis curves: Figure A.27-1 of the piping analysis for the PRHR inlet header from hot leg, Figure A.23.4-3 of the piping analysis for the RNS A discharge line to PXS from RNS check valve RNS-PL-V017A to DVI line A, and Figures A.23-4.1 and A.23.4-2 of the piping analysis for the IRWST injection line A to DVI line A.

Additionally, the inspectors verified the as-built design reports for the piping lines listed above reconciled deviations between the documents used for construction and the corresponding documents used for the design analysis, as required by ASME Section III NCA-3554. Specifically, the inspectors verified any impacts to the functional capability or LBB analyses were appropriately evaluated and reconciled.

b. Findings No findings were identified.

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.5.02.02.i (522). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.09-02.02 - Attributes of Electrical Cable installation 65001.09-02.03 - Documentation 65001.10 - Inspection of ITAAC-Related Installation of Instrument Components and Systems 65001.10-02.02.c - As Built Verification The inspectors reviewed the EQRR for the PMS cabinets, main control room/remote shutdown room (MCR/RSR) transfer panel, and MCR/RSR display and control panels listed below to determine whether the licensee assessed work packages, design changes, and nonconformances to confirm the as-built configuration, including anchorage, were seismically bounded by the as-tested and/or analyzed conditions in accordance with data sheets and design specification, and satisfy the seismic Category 1 criteria:

PMS cabinets: SV3-PMS-JW-005A, SV3-PMS-JW-005D, SV3-PMS-JD-RTS02 and SV3-PMS-JW-006A, SV3-PMS-JD-SVCB01, SV3-PMS-JD-BCCC01, SV3-PMS-JD-NICC01, SV3-PMS-JD-ILCC01, SV3-PMS-JD-NICD01, SV3-PMS-JD-ILCD01, SV3-PMS-JD-ILCA02; MCR/RSR transfer panel: SV3-OCS-JW-001; and MCR/RSR display and control panels: SV3-OCS-JC-10, SV3-OCS-JC-11.

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 installed components were bounded by the as-tested and analyzed design characteristics. The inspectors reviewed the equipment qualification summary reports and equipment qualification data packages to determine whether installation restrictions from testing were translated to the drawings and EQRRs and that any differences between as-built and as-designed condition were reconciled in accordance with approved modification or change process.

The inspectors performed a walkdown of the installed components to confirm the satisfactory installation of the Class 1E equipment, associated wiring, cables, and terminations that are qualified for room ambient temperature, humidity, pressure, and mechanical vibration was bounded by the type tests, analyses, or combination of type tests and analyses. The inspectors verified each equipments manufacturer model/serial number, location, and mounting were per the design drawings. The inspectors verified the cables and raceways had sufficient physical separation between Class 1E cables of different divisions and non-Class 1E cables and are identified by an appropriate color-coding scheme.

The inspectors reviewed the work packages and confirmed the torque values applied 17

were per the required design drawing and the torque wrenches used were within their calibration cycle.

The inspectors also interviewed licensing personnel to determine how inspection and analyses were performed for applicable nonconformances and E&DCRs issued during fabrication, handling, installation, and testing to verify deviations were bounded by the seismically analyzed conditions.

1A09 (Unit 3) ITAAC Number 2.6.03.02.i (597) / Family 08A

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.6.03.02.i (597). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.09 - Inspection of ITAAC-Related Installation of Electric and Fiber Optic Cable 65001.09-02.03 - Documentation 65001.09-02.04 - Problem Identification and Resolution 65001.A- As-Built Attributes for SSCs associated with ITAAC 65001.A.02.02 - Installation Records Review 65001.A.02.03 - Independent Assessment/Measurement Inspection 65001.A.02.04 - Review As-built Deviations/Nonconformance The inspectors reviewed the design and construction of battery racks for the Unit 3 IDS for the 24-hour, 72-hour, and spare batteries to determine whether the installation was in accordance with the ITAAC requirements. The inspectors reviewed quality records, including the design documents, work packages, inspection records, condition reports (CRs), procedures, vendor manuals, and drawings to verify:

the design was implemented in accordance with regulatory requirements, including applicable sections of the UFSAR and the Institute of Electrical and Electronic Engineers (IEEE) standards; differences between the as-built configuration and the design were reconciled in the design report; the design drawings were revised to reflect the as-built configuration by qualified personnel; issues identified during the inspection were entered into the corrective action program (CAP) in accordance with the CAP requirements; design changes were evaluated and implemented in accordance with established site procedures; and design deviations or nonconforming conditions were identified, documented, and dispositioned in accordance with site procedures.

The inspectors reviewed the licensees actions to address similar or related problems 18

that were previously identified, to verify the extent of condition and to verify the effectiveness of the licensees corrective measures.

b. Findings Introduction The inspectors identified an ITAAC finding of very low safety significance (Green) with an associated noncited violation (NCV) of 10 CFR 50, Appendix B, Criterion III, Design Control, for the licensees failure to assure the Unit 3 IDS 24-hour, 72-hour, and spare SR battery racks were installed in accordance with ITAAC 2.6.03.02.i and the approved design and was a performance deficiency (PD).

Description The inspectors reviewed CR 50095783, which was written by the licensee on January 18, 2022, to address loose through bolts, also known as loose threaded rods, on IDS battery racks in Unit 3 room 12102. Each battery cell clamp assembly has two threaded rods passing between a pair of battery cells that restrain the cells from lateral movement during seismic acceleration. These two threaded rods are to be individually tightened onto the cell clamp with two nuts each. A first nut, also known as the inner nut, is placed onto the cell clamp and it is further secured by a second nut (i.e., outer nut) that is torqued to 100 foot-pounds (ft-lbs). The CR identified 12 through bolts with rotational and/or longitudinal play along the axis of the bolt. The CR was written to evaluate and correct the identified condition of loose through bolts, which did not meet quality and installation requirements. However, during their follow up inspection, the inspectors identified that at least two of the previously identified loose through bolts were still loose along with an additional 26 loose through bolts on other battery rack clamps in Unit 3 rooms 12101, 12102, 12103, 12104, 12105, 12202, and 12204. The as-built installation of those 28 through bolts included seven bolts that could rotate by hand manipulation, 19 bolts that could also rotate by hand and had an observable gap between the inner nut and the clamp, and two bolts whose outer nuts were not correctly torqued.

The inspectors noted work packages for the installation of the battery racks, including work package SV3-IDS-DBW-1148485, required rack installation per vendor installation manual SV3-DB01-V8M-001. Vendors installation manual, SV3-DB01-V8M-001, AP1000 Class 1E 250 Volts DC (VDC) Battery Assembly Drawings: Instruction for Assembling 1E Racks, Revision 0, Section 7.5, required cell installation as described above using 5/8-inch bolts with 100 ft-lbs. of torque. This installation manual further stated that When torquing hex nuts on threaded rod, use caution to avoid bending cell clamp plates against battery jars. Hold hex nut between plates stationary and torque the hex nut on the outside of the assembly.

The installation personnel assembled the inner nut snug tight (hand tight) against the bracket to avoid bending cell clamp plates against battery jars as required in the design documentation; however, snug tight was not specified in the installation and design requirements. This was a field deviation from the installation requirements that was not evaluated and approved by authorized design personnel. Therefore, by not meeting the installation and torquing requirements for the through bolts and depending on how tight the inner nut was, some through bolt assemblies were either left still turning even after the nuts were torqued and/or not touching the cell clamp or with not adequately torqued 19

outer nuts. This left the nuts simply torqued against each other or loose, and thus not adequately securing the cell clamp plates. After a review of the applicable work packages, the inspectors noted the quality control (QC) inspection staff had accepted, by initial on the electrical equipment installation inspection records, the equipment and hardware (i.e., through bolts and nuts) were mounted correctly.

The inspectors determined the installation personnel deviated from installation and design requirements and the deviation was not evaluated and approved by authorized design personnel. In response to the inspectors questions, the licensee initiated CR 50118295 to perform an extent of condition review to identify and correct loose through bolt assemblies in all the SR battery racks. As result of this nonconforming condition, 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 this issue into its CAP as CR 50130395. The licensee completed evaluation SVP-SV0-006493, Battery Rack Loose Cell Clamp Assembly Structural Safety Evaluation, to demonstrate with reasonable assurance the design function of the battery racks would not have been impaired by the nonconformances. The licensee subsequently restored the as-built configuration of the Unit 3 IDS battery racks to match the seismically qualified condition specified by the design.

Analysis The licensees failure to assure the Unit 3 Class 1E dc and uninterruptible power supply system (IDS) 24-hour, 72-hour, and spare safety-related battery racks were installed in accordance with ITAAC 2.6.03.02.i and the approved design was a PD. Specifically, the licensee failed to assure the Unit 3 IDS batteries racks were installed in accordance with the requirements specified in SV3-DB01-V8M-001, APP-DB01-VBR-001 and APP-DB01-Z0-001. 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 PD.

Per further guidance in IMC 0613, Appendix E, "Examples of Minor Construction Issues," the inspectors determined this PD 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. This is an ITAAC finding because the acceptance criteria for ITAAC 2.6.03.02.i (Sequence 597) requires, in part, the as-built Class 1E IDS batteries listed in Table 2.6.3-1 of the Vogtle Unit 3 COL, including anchorage, are seismically bounded by the tested or analyzed conditions and can withstand seismic design basis loads without loss of safety function. The inspectors also reviewed the Appendix E examples of minor issues and found two similar examples of "not minor if" performance deficiencies. Example 1 was similar, in that the inspectors identified the as-built condition did not meet the applicable design requirements and the PD was not minor because substantial rework and additional examination was required to restore the components to the approved design. Example 11 was similar, in that the inspectors identified the licensee had failed to identify the acceptance criteria were not met for the battery racks during their quality control inspection and the PD was not minor because the components were rendered unacceptable and corrective action was required to bring SSCs into conformance.

This finding was associated with the Construction/Installation cornerstone of the Construction Reactor Safety strategic performance area. This finding was not 20

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 associated with a system; (i.e. the IDS), which is assigned to the high risk importance column of the AP1000 Construction Significance Determination Matrix.

The inspectors determined this finding was a PD of very low safety significance (Green) because the licensee was able to demonstrate with reasonable assurance through additional analyses that the design function of the Class 1E IDS batteries would not have been impaired by the PD, and the nonconforming condition was corrected such that the installation was seismically bounded by the tested or analyzed conditions.

The inspectors determined this finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Procedure Adherence 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 PD was attributed to a failure to review procedures and instructions before work was performed to validate they were appropriate for the scope of work and required changes were completed before implementation. [H.8]

Enforcement 10 CFR 50, Appendix B, Criterion III, Design Control, requires in part, Measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in § 50.2 and as specified in the license application, for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled. Measures shall also be established for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the SR functions of the structures, systems and components.

Contrary to the above, on and before January 18, 2022, the licensee failed to assure that appropriate quality standards are specified and that deviations from such standards are controlled. Specifically, the licensee failed to review and control process and quality standard deviations by field personnel installing battery racks for the Unit 3 IDS 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, APP-DB01-Z0-001 and APP-DB01-VBR-001. The licensee entered this finding into its CAP for evaluation and identification of corrective actions (CR 50130395). As immediate corrective actions, the licensee restored the as-built configuration of the Unit 3 IDS battery racks to match the seismically qualified condition specified by the design. Based on the review described above, the inspectors determined the licensee took corrective actions to address the ITAAC finding, and the nonconforming conditions had been appropriately addressed such that the acceptance criteria of ITAAC 2.6.03.02.i (597) was no longer impacted. As a result of the licensees corrective actions to restore compliance, ITAAC finding for 2.6.03.02.i is opened and closed in this report.

Because this violation was not repetitive or willful; was of very low safety significance 21

(Green); and was entered into the licensees CAP as CR 50130395, it is being treated as an NCV consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2022001-01, Failure to Review and Control Process and Quality Standard Deviations on the IDS Battery Racks).

1A10 (Unit 3) ITAAC Number 3.3.00.02a.i.b (761) / Family 01F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 3.3.00.02a.i.b (761). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.01 - Inspection of ITAAC-Related Foundations & Buildings 65001.01-02.07 - Identification and Resolution of Problem 65001.02-02.07 - Problem Identification and Resolution 65001.A- As-Built Attributes for SSCs associated with ITAAC 65001.A.02.04 - Review As-built Deviations/Nonconformance The inspectors reviewed the as-built summary report for the shield building to verify the report reconciled deviations during construction, including Table 3.3-1 wall and floor thicknesses, and concluded the as-built shield building, including the critical sections, conformed to the approved design and would withstand the design basis loads specified in the design description without loss of structural integrity or the SR functions, and without impacting compliance with the radiation protection licensing basis.

The inspectors verified the as-built summary report addressed deviations to the standard plant issued after the effective date of the as-designed summary report, as well as unit-specific deviations.

The inspectors reviewed Tables 3-1 and 3-2 of the as-built summary report to verify margin existed in the structural components and connections after reconciliation of deviations to the standard plant issued after the effective date of the as-designed summary report and site specific nonconformance and disposition reports (N&D) and E&DCRs, respectively.

The inspectors noted that design changes were reviewed in the report to identify significant changes to structural configuration (mass, thickness, etc.) and equipment layout (mass and location) and the report concluded the as-built design changes reviewed within the report did not impact the AP1000 seismic analysis model(s) or had already been incorporated.

Additionally, the inspectors reviewed Section 4.2 and Table 4-2 of the as-built summary report to determine if the as-built construction met the concrete wall thicknesses and radiation shielding requirements of the Vogtle Units 3 and 4 UFSAR Table 3.3-1 and any localized deviations from Table 3.3.-1 were appropriately evaluated and reconciled to the approved design.

b. Findings 22

Introduction The inspectors identified an ITAAC finding of very low safety significance (Green) with an associated NCV of 10 CFR 52.99(c)(1), ITAAC Closure Notification, for the licensees failure to submit an ITAAC closure notification (ICN) for Unit 3 ITAAC 3.3.00.02a.i.b (761) that contained sufficient information to demonstrate the prescribed inspections, tests, and analyses had been performed and the prescribed acceptance criteria were met and was a performance deficiency.

Description On December 8, 2021, the licensee submitted the ICN for Vogtle Unit 3 ITAAC 3.3.00.02a.i.b to the NRC. Subsequently, during the week of December 12, 2021, NRC inspectors determined the ICN did not contain sufficient information to demonstrate the prescribed inspections, tests, and analyses had been performed and the acceptance criteria were met.

The acceptance criteria of the ITAAC requires, in part, that deviations during construction, including those from the Vogtle Units 3 and 4 UFSAR Table 3.3-1 wall and floor thicknesses, be reconciled to demonstrate the as-built structures conform to the approved design and will withstand the design basis loads without loss of structural integrity or the SR functions, and without impacting compliance with the radiation protection licensing basis.

The inspectors reviewed SV3-1208-GCR-001, VEGP Unit 3 As-Built Summary Report:

Shield Building, Revision 1, and noted N&D SV3-CC01-GNR-000451 was still open.

The inspectors reviewed the N&D and determined it was associated with out of tolerance wall thicknesses in the shield building reinforced concrete cylindrical wall. The inspectors further determined some of these deviations had not been repaired or reconciled to the approved design and, as a result, it was not possible to conclude the ITAAC acceptance criteria were met.

In response to the inspectors questions, the licensee withdrew the ICN and issued N&D SV3-CC01-GNR-000686, which superseded N&D SV3-CC01-GNR-000541, to address areas of the shield building concrete wall with thickness not meeting the requirements of the Vogtle Units 3 and 4 UFSAR Table 3.3-1. The as-built summary report for the shield building was also updated to reflect the closure of N&D SV3-CC01-GNR-000686. As documented in N&D SV3-CC01-GNR-000686, the nonconforming areas were either repaired to bring them into compliance with the thickness requirements of the VEGP Units 3 and 4 UFSAR or construction deviations were reconciled in accordance with UFSAR Table 3.3-1, Note 15 to demonstrate the as-built structures would withstand design basis loads without loss of structural integrity or safety functions and without impacting compliance with the radiation protection licensing basis.

The inspectors reviewed the updated as-built summary report for the shield building to verify the report reconciled deviations during construction, including Table 3.3-1 wall and floor thicknesses, and concluded the as-built shield building, including the critical sections, conformed to the approved design and would withstand the design basis loads specified in the Design Description without loss of structural integrity or the SR functions, and without impacting compliance with the radiation protection licensing basis. The inspectors verified the as-built summary report addressed deviations to the standard 23

plant issued after the effective date of the as-designed summary report as well as unit-specific deviations. The inspectors reviewed Tables 3-1 and 3-2 of the as-built summary report to verify margin existed in the structural components and connections after reconciliation of deviations to the standard plant issued after the effective date of the as-designed summary report and site specific N&Ds and E&DCRs, respectively. The inspectors noted design changes were reviewed in the report to identify significant changes to structural configuration (mass, thickness, etc.) and equipment layout (mass and location) and the report concluded the as-built design changes reviewed within the report did not impact the AP1000 seismic analysis model(s) or had already been incorporated. Additionally, the inspectors reviewed Section 4.2 and Table 4-2 of the as-built summary report to determine if the as-built construction met the concrete wall thicknesses and radiation shielding requirements of the Vogtle Units 3 and 4 UFSAR Table 3.3-1 and found any localized deviations from Table 3.3.-1 were appropriately evaluated and reconciled to the approved design.

Analysis The inspectors determine the licensees failure to submit an ICN that contained sufficient information to demonstrate that the prescribed inspections, tests, and analyses had been performed and the prescribed acceptance criteria were met was a PD.

The inspectors evaluated the PD in accordance with IMC 0613, Power Reactor Construction Inspection Reports. The PD involved the failure to provide complete and accurate information, could be associated with a specific ITAAC, and was material to the acceptance criteria of that ITAAC. For violations of this nature, IMC 0613 outlines a dual path that involves using both the traditional enforcement process and the construction reactor oversight process (cROP). The inspectors evaluated the PD using both processes. The inspectors reviewed examples of 52.99 violations provided in Section 6.9 of the Enforcement Policy. ITAAC management, however, is a construction program listed in IMC 2504, Construction Inspection Program: Inspection of Construction and Operational Programs. Construction programs, including ITAAC management, are within the scope of the cROP. After proceeding along both paths, the inspectors determined that following either led to the same destination, a violation of 10 CFR 52.99(c)(1) and, therefore, using both processes was superfluous. The inspectors evaluated both routes and determined that using the cROP was appropriate in this case given that PD involved a construction program, could be associated with a specific ITAAC, and was material to the acceptance criteria of that ITAAC. As a result, the inspectors determined traditional enforcement did not apply and proceeded to assess the PD using the cROP.

The PD was considered more than minor and a finding because it represented a substantive failure to implement a program, process, procedure, or quality oversight function. Specifically, the licensee failed to develop an ICN that accurately reflected ITAAC completion as supported by verifiable documents and traceable records. As a result, the ICN would have been rejected by the NRC, if the licensee had not voluntarily withdrawn it.

The inspectors evaluated the finding in accordance with IMC 2519, "Construction Significance Determination Process," Appendix A, "AP 1000 Construction Significance Determination Process," dated October 26, 2020, and determined the finding was not associated with a security program, or an operational program listed in IMC 2504, but 24

involved the requirements of a construction program listed in IMC 2504. The inspectors also determined the finding could be associated with a specific ITAAC and was material to the ITAAC acceptance criteria since it was associated with deviations that had not been repaired or reconciled to the approved design as required by the ITAAC. The inspectors determined the finding was associated with the Inspection/Testing cornerstone of the Construction Reactor Safety strategic performance area. The finding did not involve a repetitive, NRC identified omission of a program critical attribute.

Based on review of N&D SV3-CC01-GNR-000686, the inspectors determined the design function of the affected structure would not have been impaired by the deficiency. As a result, the inspectors concluded the finding was of very low safety significance (Green).

The inspectors reviewed the finding for a possible cross-cutting aspect in accordance with IMC 0613 Appendix F, Construction Cross-Cutting Areas and Aspects, dated November 4, 2020, and determined the finding had a cross-cutting aspect of Conservative Bias in the area of Human Performance. The proximate cause of the PD was attributed to the failure to use conservative decision making when submitting the ICN without all the determination basis input documents finalized. [H.14]

Enforcement 10 CFR 52.99(c)(1), ITAAC Closure Notification, requires, in part, that the ICN must contain sufficient information to demonstrate that the prescribed inspections, tests, and analyses have been performed and that the prescribed acceptance criteria are met.

Contrary to the above, on December 8, 2021, the licensee failed to provide sufficient information in the ICN to demonstrate that the prescribe inspections, tests, and analyses had been performed and that the prescribed acceptance criteria were met. Specifically, the ICN did not contain sufficient information to demonstrate that the wall thickness requirements of UFSAR Table 3.3-1 had been met or that construction deviations from the thickness and tolerances specified in Table 3.3-1 had been reconciled. As a result, it was not possible to determine, based on the information provided, the as-built structures conformed to the approved design and would withstand the design basis loads without loss of structural integrity or the SR functions, and without impacting compliance with the radiation protection licensing basis.

As immediate corrective actions, the licensee withdrew the ICN. Subsequently, N&D SV3-CC01-GNR-000541 was superseded by N&D SV3-CC01-GNR-000686 to address areas of the shield building concrete wall with thicknesses not meeting the requirements of UFSAR Table 3.3-1 and the as-built summary report for the shield building was updated to reflect the closure of N&D SV3-CC01-GNR-000686. Based on the review described above, the inspectors determined the licensee took corrective actions to address the ITAAC finding, and the nonconforming conditions had been appropriately addressed such that the acceptance criteria of ITAAC 3.3.00.02a.i.b (761) was no longer impacted. As a result of the licensees corrective actions to restore compliance, ITAAC finding for 3.3.00.02a.i.b is opened and closed in this report.

Because this violation was not repetitive or willful; was of very low safety significance (Green) and was entered into the licensees CAP as CR 50127060, it is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy (NCV 05200025/2022001-02, Failure to Provide Sufficient Information in the ICN for ITAAC 761).

The SIT was conducted by Chicago Bridge and Iron Services in the accompaniment of Westinghouse, ILRT Inc., and the licensee. The inspectors reviewed procedures and records, conducted walkdowns, performed test observations, and interviewed personnel to assess performance and compliance with rules and regulations, license conditions, site procedures, and ASME Code requirements.

The inspectors performed a pre-test walkdown and general inspection of accessible portions of the containment interior and exterior surfaces; attended pre-job, safety, and infrequent test evolution briefings; observed test equipment setup and performance; and interviewed test personnel regarding procedural limitations, examination techniques, and ASME Code requirements. The inspectors reviewed the pneumatic test procedure and related drawings, SIT chart recorder data, calibration records and test prerequisites, and personnel qualifications and certifications.

The inspectors reviewed the following information to determine if the inspection attributes were met:

procedures and work instructions were approved by authorized personnel; current procedure revision was available and in use at the test location by test personnel; records existed for those welds/joints that were vacuum box tested prior to the SIT due to being inaccessible; following test completion, the test data was evaluated by the licensee and its 35

contractors (ILRT Inc.);

test data was accurate and precisely recorded; deficiencies and test interruptions or continuations were handled in accordance with approved procedures and documented in the test narrative log; preliminary test results, records, data, and analyses were as expected and any discrepancies were logged; test anomalies, problems, interruptions, and/or deficiencies recorded in the logs were documented and evaluated in accordance with procedures; and the disposition of any deviations and corrective measures, if any, were documented and evaluated, and required retests or leakage examinations were performed, as necessary.

The inspectors verified through observation the following activities to determine if the inspection attributes were met:

administrative test controls were followed; a qualified (licensed) nuclear inspector was present during the SIT and at the time of the leakage examinations; containment was pressurized to 1.1 times its design pressure and the maximum permissible test pressure was not exceeded; test pressure was retained for a minimum of 10 minutes then reduced to a specified fraction of the pressure for leakage examinations of joints, penetrations, connections, and high stress regions; after achieving 50% of the final test pressure, the rate of containment pressurization was increased in increments of approximately 1/10 of the test pressure up to 1.10 times the design pressure; maximum rate of containment pressurization and depressurization were specified by procedure and adhered to throughout the SIT; verified hold times for pressure stabilization and depressurization were specified and adhered to during the test; depressurization rate of the containment and unloading increments paralleled the loading cycle; maximum permissible test pressure was maintained for a minimum of 10 minutes then reduced to the greater of either the design pressure or the specified fraction of the test pressure for the leakage examinations; adverse weather or environmental conditions that could impact test results were appropriately monitored and taken into consideration during the test; logging of test parameters, leakage rates, observations was performed at a pre-determined periodicity; and observed leakage examinations (solution/bubble film test technique) of various welds, reviewed sketches, and verified examinations of applicable joints, penetrations, and connections and regions of high stress (such as seam welds, welds in the shell and dome, nozzle welds, welds of penetration sleeves) were performed in accordance with ASME Subsection NE.

The inspectors also performed the following activities to determine if the inspection attributes were met:

verified by observation, interviews, and walkdowns the containment structure was pressurized using a medium that was reasonably clear, dry, nonflammable, 36

and free of contaminants; verified by observation and data review the containment displacement was appropriately monitored during the test and did not exceed design parameters; verified through interviews the testing was coordinated, including "abort" criteria established; and verified through interview and preliminary data review no structural damage resulted from the test.

The inspectors verified through walkdowns, interviews, and observation the type, sensor location, range, accuracy, and calibration of instrumentation met requirements and standards, were specified, and indicating as expected. Specifically, the inspectors verified:

displacement instrumentation used to measure overall deformation and deflection of the CV were installed at several points and elevations on the vessel; humidity and temperature sensors were located at several locations and elevations throughout the containment and trending as expected; and pressure gauges, recorders, displays, and other required test equipment were within the range and accuracy specified, calibrations were current, and instruments were in service prior to test.

a. Inspection Scope The inspectors reviewed issues entered into the licensee's CAP daily to assess issues that might warrant additional follow-up inspection, to assess repetitive or long-term issues, to assess adverse performance trends, and to verify the CAP appropriately included regulatory required nonsafety-related SSCs. The inspectors periodically attended the licensee's CAP review meetings, held discussions with licensee and contractor personnel, and performed reviews of CAP activities during the conduct of other baseline inspection procedures. The inspectors reviewed conditions entered into the licensee's CAP to determine whether the issues were classified in accordance with the licensee's quality assurance program and CAP implementing procedures. The inspectors reviewed corrective actions associated with conditions entered into the CAP to determine whether appropriate actions to correct the issues were identified and implemented effectively, including immediate or short-term corrective actions, in accordance with the applicable quality assurance program requirements and 10 CFR 50, Appendix B, Criterion XVI. Additionally, the inspectors reviewed the corrective actions taken to determine whether they were commensurate with the significance of the associated conditions in accordance with the licensee's CAP implementing procedures.

The inspectors completed reviews of CAP entry logs to verify issues from all aspects of the project, including equipment, human performance, and program issues, were being identified by the licensee and its contractors at an appropriate threshold and entered into the CAP as required by licensee's CAP implementing procedures.

b. Findings No findings were identified.

1P02 Construction QA Criterion 3 35007-A3 - Appendix 3. Inspection of Criterion III - Design Control

a. Inspection Scope 39

The inspectors reviewed design change documents associated with Roxtec electromagnetic compatibility (EMC) glands in SR Class 1E electrical panels or enclosures to determine whether the necessary inputs were included in the design package governing their installation. Specifically, the inspectors reviewed E&DCR APP-GW-GEF-2640, Application of EMC Glands, Revision 0, for evaluation of the applicable design inputs.

b. Findings Introduction The inspectors identified a construction finding of very low safety significance (Green) with an associated NCV of 10 CFR 50, Appendix B, Criterion III, Design Control, for the licensees failure to assure applicable regulatory requirements and the design basis, as defined in § 50.2 and as specified in the license application, for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions. Specifically, the licensees failure to evaluate applicable design inputs in the design package (E&DCR APP-GW-GEF-2640) that installed EMC glands in Class 1E plant electrical enclosures was a PD.

Description On November 2, 2021, the inspectors identified applicable design inputs were missing from the design package (APP-GW-GEF-2640) that addressed requirements for installation of EMC shielding and grounding glands. These glands were classified as NSR Class D, seismic Category II components. The glands were installed on numerous Class 1E panels throughout the plant. The design package (APP-GW-GEF-2640) was completed and issued without documenting the seismic qualification of the EMC glands.

APP-G1-V8-001, AP1000 Electrical Installation Specification, Revision 11, Section 2.1 referenced APP-GW-G1-014, AP1000 Plant Nuclear Safety Classification and Seismic Requirement Methodology, Revision 9. In addition, APP-G1-V8-001, Section 3.1.2 stated, in part, Westinghouse safety Classification D seismic Category II components shall require a quality program and Section 3.6.4 stated, in part, Class 1E instrumentation, control, and power distribution cabinets are typically supplied in their as-qualified condition (including required EMC mitigation features). The use of additional EMC glands or seals on Class 1E enclosures shall conform to the qualified configuration and must be approved by engineering using design change control processes.

APP-GW-G1-014, Section 6.1.4 stated, in part, Class D this class is nonsafety-related with some additional requirements on procurement, inspections or monitoring. In addition, Section 7.1.2, Seismic Category II, stated seismic Category II shall apply to all plant SSCs which perform no nuclear safety function, and whose continued function is not required, but whose structural failure or interaction could degrade the functioning of a safety class SSC to an unacceptable safety level. Seismic Category II SSCs shall be specified, designed and/or analyzed so that the safe shutdown earthquake will not cause unacceptable structural interaction or failure.

APP-GW-GAP-420, Engineering and Design Coordination Report, Revision 11, Section 5.8 stated The Technical Justification, Design Inputs reviewed, and Design 40

Outputs changed shall be recorded in the disposition of the E&DCR and shall explain in detail why the design change is necessary and acceptable. The inspectors reviewed APP-GW-GEF-2640 and noted the required technical justification for the seismic design input for the Roxtec EMC glands was missing from the engineering package.

The licensee issued CR 50113095, CR 50112869, CAP-IR-2021-11884, Engineering Service Request (ESR) 50112865 and Technical Evaluation (TE) 60031294 to address the missing seismic input. As a result, the licensee issued two new E&DCRs (APP-GW-GEF-519 and APP-GW-GEF-529) to supplement APP-GW-GEF-2640, documenting the technical design input details for seismic qualification.

Analysis The licensees failure to evaluate applicable design inputs in the design package (E&DCR APP-GW-GEF-2640) that installed EMC glands in Class 1E plant electrical enclosures was a PD. 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 PD. Per further guidance in IMC 0613, Appendix E, "Examples of Minor Construction Issues," the inspectors determined this PD was of more than minor safety significance, and thus a finding, because it represented a substantive non-conservative error in a design document that defines the technical requirements for plant Class 1E electrical enclosures and justification was required by the licensee to ensure the as-built seismic Category II, Class D component did not adversely affect the ability of plant Class 1E electrical enclosures to perform their intended safety function during a seismic event.

The inspectors also reviewed the Appendix E examples of minor issues and found two similar examples of a "not minor if" PD. Examples 1 and 13 were similar, in that the inspectors identified the licensee failed to implement technical and quality requirements leaving the Class 1E electrical enclosures unacceptable or indeterminate without subsequent substantive engineering justification. The inspectors determined the finding was not material to an ITAAC and therefore it was a construction finding because the EMC gland seismic qualifications did not impact the seismic qualifications and acceptance criteria of ITAAC related 1E panels in which the glands were installed.

The inspectors determined the finding was associated with the Design/Engineering cornerstone of the Construction Reactor Safety strategic performance area. This finding was not associated with a security program; it was not associated with an IMC 2504 operational/construction program; it was not associated with a specific ITAAC and was not material to the ITAAC acceptance criteria; 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, AP1000 Significance Determination Process, dated October 26, 2020, the inspectors determined this finding was of very low safety significance (Green) because the licensee subsequently revised the design documents to include seismic evaluation and testing results which determined the EMC gland would not affect seismic Category I SSCs during a seismic event and the nonconforming conditions were corrected such that the gland installation was seismically bounded by the tested or analyzed conditions.

The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Change Management in the area of Human Performance in accordance with IMC 0613, Appendix F, Construction Cross-41

Cutting Areas and Aspects, dated November 4, 2020. The proximate cause of the PD was attributed to the licensees failure to implement a process where managers maintain a clear focus on nuclear safety when implementing the change management process to ensure significant unintended consequences are avoided. [H.3]

Enforcement UFSAR Section 3.2.2.6, Equipment Class D, states in part, when Class D structures, systems, and components are located near a Class A, B, or C structure, system, or component, the requirements for seismic Category II may apply.

UFSAR Section 3.2.1.1.2, Seismic Category II (C-II), states in part, seismic Category II structures, systems, and components are designed so that the safe shutdown earthquake does not cause unacceptable structural failure of or interaction with seismic Category I items. This section also states pertinent portions of 10 CFR 50, Appendix B apply to the analysis and design of seismic Category II structures, systems, and components. The quality assurance requirements for the analysis and design of seismic Category II structures, systems, and components are performed in accordance with the Westinghouse AP1000 quality plan.

10 CFR 50, Appendix B, Criterion III, "Design Control," states in part, "measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in § 50.2 and as specified in the license application, for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled.

Contrary to the above, on November 2, 2021, the licensee failed to establish measures and include provisions to assure that appropriate quality standards were specified and included in design documents for installation of EMC glands in plant Class 1E electrical enclosures. Specifically, the design documents failed to address and analyze design inputs that were applicable to the installation of seismic Category II, Safety Classification D, EMC glands. As a result, NSR components were installed on SR components without a seismic Category II analysis. The licensee entered this finding into its CAP for evaluation and identification of appropriate corrective actions as CR 50125873. As immediate corrective actions, the licensee issued new E&DCRs APP-GW-GEF-519 and APP-GW-GEF-529 that analyzed, and provided seismic testing results, indicating the seismic input for the EMC glands met the as-built seismic Category II, Class D component and would not adversely affect the ability of plant Class 1E electrical enclosures to perform their intended safety function during a seismic event.

Because this violation was not repetitive or willful, was of very low safety significance (Green), and was entered into the licensees CAP as CR 50125873, this violation is being treated as an NCV consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2022001-03, Failure to Evaluate Applicable Design Inputs for EMC Glands). This construction finding is opened and closed in this report.

4. OTHER INSPECTION RESULTS 4OA3 Follow-up of Licensee Reports, URIs, NCVs, and VIOs 42

.1 (Closed) NCV 05200025/2021005-05, Failure to Qualify EPAs in Accordance with IEEE 317 The inspectors performed a document review of the licensees corrective actions for NCV 05200025/2021005-05, Failure to Qualify EPAs in Accordance with IEEE 317, which was documented in NRC Inspection Report 05200025/2021005, 05200026/2021005 (ML21316A057). The review was to determine whether the corrective actions taken by the licensee were sufficient to address the issue and to verify the acceptance criteria for the related ITAAC could be met. The violation was associated with the licensees failure to consider all significant types of degradation that would have an adverse impact on electrical penetration assembly (EPA) functional capability for seismic and environmental qualification during a design basis accident.

The violation represented an ITAAC finding because it was material to the acceptance criteria of ITAAC 2.2.01.05.i (98), in that, if left uncorrected, the licensee may not have been able to demonstrate the acceptance criteria of the ITAAC was met. The acceptance criteria of this ITAAC requires, in part, that the as-built equipment (including anchorage) is seismically bounded by the tested or analyzed conditions and a report exists that concluded the as built Class 1E equipment and the associated wiring, cables, and terminations identified in Table 2.2.1-1 as being qualified for a harsh environment are bounded by type tests, analyses, or a combination of type tests and analyses.

The inspectors reviewed E&DCR APP-EY01-GEF-051 to verify environmental qualification program changes document the analysis for EPAs.

Regarding EPA qualification, the updated environmental qualification analysis described and justified the as-tested configuration. Specifically, the E&DCR revised the environmental qualification to clarify how the requirements of IEEE 317-1987 and IEEE 344-1987 were met, how excluded components were considered, and why there would be no additional impact from excluded components. The updated environmental qualification analysis concluded seismic loads would not be transferred from the excluded components or external items (e.g., termination box, raceways, external cables) to the EPA through the cable. The E&DCR approved adding the analysis for the as-tested assembly to the following environmental qualification program documents:

APP-EY01-VBR-001, Revision 4 APP-EY01-VBR-002, Revision 4 APP-EY01-VBR-003, Revision 5 APP-EY01-VBR-004, Revision 5 Regarding EPA as-built configurations, the E&DCR description included the as-tested configuration was intended to be generic since it was performed before the final AP1000 plant design configurations were complete; therefore, analysis was created to allow for the differences in each installation. The inspectors noted IEEE 344-1987 allowed for the use of analysis in seismic qualification. The inspectors also noted the licensee had a methodology in place to analyze the as built configurations, as described in APP EY01-E0C-002, Methodology for the Determination of Electrical Penetration Assembly (EPA)

Weight.

Regarding seismic benchmark acceptance criteria, the licensee provided analysis in the 43

E&DCR that justified calculating seismic acceleration by applying a static coefficient to previous seismic testing data. Specifically, the actual seismic test (as tested) performed by the EPA vendor produced an acceleration that exceeded the calculated seismic acceleration. The licensee provided further justification that the calculated seismic acceleration and as-tested seismic acceleration envelope the AP1000 peak acceleration by a significant margin.

Based on the review described above, the inspectors determined the licensee took corrective actions to address the violation and the potential related impacts to the ITAAC have been appropriately addressed such that the acceptance criteria of ITAAC 2.2.01.05.i (98) can be met. NCV 05200025/2021005-05 is closed.
