SUMMARY

OF FINDINGS Inspection Report (IR) 05200025/2020003, 05200026/2020003; 07/01/2020 through 09/30/2020; Vogtle Electric Generating Plant (VEGP) Units 3 and 4, Integrated Inspection Report.

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

One construction finding of very low safety significance (Green) with an associated non-cited violation (NCV) in the Inspection/Testing Cornerstone was 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 (Green) with an associated NCV of Title 10 of the Code of Federal Regulations (10 CFR 50), Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to perform leakage examinations of two American Society of Mechanical Engineers (ASME) Class 2, pressure-retaining, weld joints for containment penetrations P27 and P28 to satisfy the requirements of ASME Section III.

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 unacceptable or indeterminate, and required substantive corrective action. The inspectors determined this finding was not associated with an 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. The inspectors determined this finding was of very low safety significance because the licensee was able to demonstrate the design function of the applicable structure (containment vessel) would not be impaired by successfully reperforming a pneumatic test of the affected welds. The licensee entered this issue into its corrective action program as condition report (CR) 50056351. The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect Avoid Complacency, in the area of Human Performance. Specifically, the licensee failed to ensure the contract individuals recognized and planned for the possibility of mistakes, latent problems, or inherent risk, even while expecting successful outcomes. The licensee did not ensure the contractor understood the location of the welds, ensure obstructions were not present, and ensure supporting procedures or drawings were referenced to satisfactorily perform targeted ASME Section III weld examinations during the pneumatic test.

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 standards.

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 requirements. The inspectors reviewed pneumatic test procedure and related drawings, SIT chart recorder data, calibration records and test prerequisites, and personnel qualifications and certifications.

17 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 were evaluated by the licensee and its 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 properly 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 which 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

18 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 that the containment structure was pressurized using a medium that was reasonably clear, dry, nonflammable, and free of contaminants;

verified by observation and data review that containment displacement was appropriately monitored during the test and did not exceed design parameters;

verified through interviews that testing was adequately coordinated, including appropriate abort criteria established; and

verified through interview and preliminary data review that no structural damage resulted from the test.

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

Specifically, the inspectors verified if:

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.

b. Findings Introduction A construction finding of very low safety significance (Green) with an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was identified by the inspectors on July 17, 2020, for the licensee's failure to perform leakage examinations of two ASME Class 2, pressure-retaining, mechanical weld joints for containment penetrations P27 and P28. During the pneumatic SIT of the Unit 3 containment vessel, leakage examinations of welds SV3-SGS-PY-C03A-3 and SV3-SGS-PY-C03B-3 were not performed, as required by procedure 165766-830-05-PR-000010, "Pneumatic Testing of Unit 3 Containment Vessel to satisfy the requirements of ASME Section III.

Description Between July 5 and 7, 2020, the licensee performed a SIT of the Vogtle Unit 3 CV to satisfy the requirements of ASME Section III, Article NE-6000, Testing. Article NE-6000 required the vessel be pressurized to 1.1 times its design pressure for a minimum of 10 minutes prior to being depressurized to a lower value to allow for leakage examination of joints/welds, connections, and regions of high stress in accordance with paragraph NE- 6324. The scope of welds/joints required to be

19 examined were specified in procedure 165766-830-05-PR-000010, and included inspections of the Class 2, pressure-retaining, flued head to guard pipe welds for containment penetrations P27 and P28 or welds SV3-SGS-PY-C03A-3 and SV3-SGS-PY-C03B-3. Specifically, step 5.5.2 of the procedure required, in part, CBIS solution film test (leakage examination) the exterior pressure boundary welds as required and as specified by drawings 165766-830-05-SK-46101 through 165766-830-05-SK-46103 (Accessible Welds). Additionally, these welds were a part of the mechanical penetrations required to be inspected under paragraph NE-6712 of ASME Section III.

Prior to a July 17, 2020 NRC interview with the licensees weld examiners, it was discovered that mechanical weld joints SV3-SGS-PY-C03A-3 and SV3-SGS-PY-C03B-3 were not inspected as required by procedure 165766-830-05-PR-000010 and as specified in drawing 165766-830-05-SK-46102. The licensee captured this issue in the corrective action program as Condition Report (CR) 50056351. A preliminary investigation into the cause identified the examiners field of view was obstructed by scaffolding in place at the time of the pneumatic test and the obstruction prevented the examiners from seeing and locating the missed welds.

Analysis The inspectors determined that the failure to perform ASME Section III examinations in accordance with SIT Procedure 165766-830-05-PR-000010, as required by 10 CFR Part 50, Appendix B, Criterion V, was a performance deficiency.

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 the guidance in IMC 0613, Power Reactor Construction Inspection Reports, Appendix E, Examples of Minor Construction Issues, the inspectors determined the performance deficiency was of more than minor significance because it was associated with the Procedure Quality attribute of the Construction Reactor Safety - Inspection/ Testing Cornerstone and adversely affected the cornerstone objective to ensure programs and processes are adequately developed and implemented to inspect and test structures, systems, and components. The inspectors also reviewed the appendix E examples of minor issues and found one similar example of a not minor if performance deficiency. Example 22 was similar, in that the procedural step was required by Appendix B Criterion V as well as the ASME Code.

The inspectors determined this finding was not associated with an 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. In accordance with IMC 2519, Construction Significance Determination Process, appendix A, AP 1000 Construction Significance Determination Process, dated October 26, 2020, the inspectors determined the finding was associated with, the containment, a structure assigned to the intermediate risk column of the AP1000 Construction Significance Determination Matrix, and reasonable assurance could not be provided that the finding would not impair a portion of the containment design function (row 2 of the matrix). Specifically, because the licensee failed to perform examinations of SV3-SGS-PY-C03A-3 and SV3-SGS-PY-C03B-3, reasonable assurance could not be provided that the respective containment penetrations (P27 and P28) could support

20 the design function of CNS as a leak-tight barrier. The inspectors determined this finding was a performance deficiency of very low safety significance (Green) based on its placement in intermediate risk column and row 2 of the matrix.

The licensee subsequently performed a leakage examination using the vacuum box test method for these two welds and verified there was zero leakage in accordance with ASME Section III requirements.

In accordance with IMC 0613, Appendix F, Construction Cross-Cutting Areas and Aspects, the finding was determined to be indicative of present licensee performance and was associated with the cross-cutting aspect Avoid Complacency, in the area of Human Performance, because the licensee failed to ensure the contract individuals recognized and planned for the possibility of mistakes, latent problems, or inherent risk, even while expecting successful outcomes. The licensee did not ensure the contractor understood the location of the welds, ensure obstructions were not present, and ensure supporting procedures or drawings were referenced to satisfactorily perform targeted ASME Section III weld examinations during the pneumatic test [H.12].

Enforcement 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings,"

requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and accomplished in accordance with these instructions, procedures, or drawings.

Contrary to the above, on July 7, 2020, the licensee failed to accomplished activities affecting quality in accordance with these instructions, procedures, or drawings.

Specifically, step 5.5.2 of procedure 165766-830-05-PR-000010, "Pneumatic Testing of Unit 3 Containment Vessel," required in part that CBIS solution film test (leakage examination) the exterior pressure boundary welds as required and as specified by drawings 165766-830-05-SK-46101 through 165766-830-05-SK-46103 (Accessible Welds). Welds SV3-SGS-PY-C03A-3 and SV3-SGS-PY-C03B-3 were identified on CBIS drawing 165766-830-05-SK-46102, Revision 2, as welds requiring solution film testing (leakage examination), however the licensee failed to perform leakage examinations of welds SV3-SGS-PY-C03A-3 and SV3-SGS-PY-C03B-3 for penetrations P27 and P28 in accordance with Step 5.5.2 of CBIS procedure 165766-830-05-PR-000010 to meet ASME Code Section III.

The licensee entered this issue into its corrective action program as CR-50056351 and has performed successful pneumatic tests on the welds in question as corrective actions. Because this violation was not repetitive or willful, was of very low safety significance (Green), and was entered into the licensees corrective action program, it is being treated as an NCV consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2020003-01, Failure to Perform ASME Section III Leakage Examinations in Accordance with Procedure).

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

65001.F-02.01-Design Document Review

65001.F-02.04-General QA Review For the CV, the inspectors reviewed design documents, implementing procedures and interface policies that govern the design control program associated with the design of the CV, to verify compliance with the regulatory requirements of Criterion III, Design Control, of Appendix B, to 10 CFR Part 50, with the Vogtle 3&4 Updated Final Safety Analysis Report (UFSAR), and with the applicable requirements of Division 1, Subsection NC, Class 2 Components, and Subsection NE, Class MC Component, of the ASME Boiler and Pressure Vessel (B&PV) Code,Section III, Rules of Construction of Nuclear Facility Components.

The inspectors reviewed the CV design specification and the design report to verify the results, for the various load combination, including seismic, were within the allowable limits of ASME Section III to verify if the CV would meet its design safety function as described in the UFSAR. Specifically, the inspectors reviewed:

the functional requirements as defined by the Westinghouse Electric Company (WEC) design specification (i. e., component classification, design requirements, environmental conditions and transients, loading and seismic requirements, load combinations, permissible stresses) were consistent with the UFSAR;

CBIS design calculations to determine if the requirements of the design specifications were appropriately translated into the calculations, including seismic loads, and any issues were appropriately resolved;

design calculations, including material properties, conformed to the requirements of ASME Section III, Division 1, Subsections NC and NE;

drawings and dimensions used in design calculation to verify that as-built configuration was reflected in the analysis;

selected deviations and nonconformance were dispositioned and reconciled to maintain compliance with the Code.

The inspectors reviewed software and personnel qualifications for ASME related design work for the following:

ANSYS Version 19.2, to perform finite element analysis to perform stress analysis and fatigue evaluation of CV components per ASME B&PV Code,Section III;

ANSYS Version 11.0, used by Ishikawajima Harima Heavy Industries Corporation (IHI) to perform finite element modelling of CV Personnel Airlock; and

verification of implementation of UFSAR Section 3.9.1.2, Computer Programs Used in Analysis.

22 The inspectors also verified that: (1) quality standards were specified and included in design documents; (2) independent verifications and checks were integrated into the process and were being performed; (3) design interface between client and contractor were documented; and (3) design changes were being effectively controlled and approved by original design organization. The inspectors also discussed the Design Control program with CBIS and Westinghouse management and technical staff.

The inspectors reviewed a sample of personnel qualification records for engineers who performed design activities, specifically for design calculations for CV and its components. This review was to verify that the design documents were created and verified by qualified engineers, and that personnel involved in the development of design documents met CBIS, WEC and their contractors procedure requirements for approvers, reviewers, and verifiers and also met the independent verification requirements of ASME B&PV Code,Section III and ASME NQA-1-1994 Edition, Quality Assurance Requirements for Nuclear Facility Applications. The NRC inspection team reviewed sample qualification records of registered professional engineering personnel from CBIS, WEC and IHI that were involved in certifying CV design documents and conformed that the qualification records were current and met the requirements of ASME B&PV Code,Section III, Mandatory Appendix XXIII, Qualifications and Duties of Certifying Engineers Performing Certification Activities.

For software control, the inspectors reviewed CBISs software validation and verification process for the ANSYS Finite Analysis software used for design analysis and calculations of CV and its components and confirmed that the software was commercially procured, verified and validated prior to its use and installation. The NRC inspection team verified that each new version of the ANSYS, including latest version 19.2, was subject to verification through regression testing to previous software versions known to be acceptable, and that the calculations supported the conclusions. The NRC inspection team also confirmed that CBIS had evaluated all incoming ANSYS software error reports for their impact on previous design analysis and calculations. Further, the NRC inspection team reviewed CBIS audit of IHI software quality assurance program and confirmed that CBIS have verified IHIs verification and validation of ANSYS software program for use in CV airlock design analysis.

For procurement document control, the inspectors reviewed purchase order issued by the licensee and WEC to CBIS to verify that the requirements identified in the procedures were imposed in the applicable purchasing documents. The inspectors verified that the licensee and WEC purchase orders (POs) defined contract deliverables, instructions for the disposition of nonconformances, access rights, and provisions for the extension of contractual requirements to CBIS. Further, the NRC inspection team verified if the safety-related POs reviewed included clauses invoking the provisions of 10 CFR Part 21, Reporting of Defects and Noncompliance, and requiring CBIS to conduct safety-related work under its approved quality assurance (QA) program. In addition, the NRC inspection team reviewed CBIS PO to IHI for procurement of CV personnel airlock design and verified if CBIS had invoked all applicable technical, quality and regulatory requirement for procurement of safety-related SSCs.

The inspectors reviewed issues entered by the licensee, CBIS and WEC corrective action program (CAP) to assess issues that might warrant additional follow-up inspection, to assess repetitive or long-term issues, to assess adverse performance

23 trends, and to verify if the CAP appropriately included regulatory required non-safety related SSCs. The NRC inspection team reviewed conditions entered the CBIS and WEC CAP to determine whether the issues were appropriately classified in accordance with the licensee, CBIS quality assurance program and CAP implementing procedures. The NRC inspection team 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, Corrective Action. Additionally, the NRC inspection team 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 NRC inspection team completed reviews of CAP 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 the licensee and its contractors CAP implementing procedures.

The inspectors reviewed a sample of audits to verify implementation of the licensee, CBIS and WEC audit programs. The NRC inspection team verified that CBIS prepared and approved plans that identify the audit scope, focus, and applicable checklist criteria before the initiation of the audit activity. The inspectors determined if the audit reports contained a review of the relevant QA criteria VII, Control of Purchased Material, Equipment and Services, of Appendix B to 10 CFR Part 50 for the activities that individual contractor performed, as well as documentation of pertinent contractor guidance associated with each criterion. For audits that resulted in findings, the inspectors verified that the contractor had established a plan for corrective action and that WEC and CBIS had reviewed and approved the corrective action and verified its satisfactory completion and proper documentation in a timely manner.

The inspectors also verified if CBIS performed external audits commensurate with the required frequencies specified in the CBIS quality assurance manual (QAM),

associated procedures, and the applicable section(s) of the ASME B&PV Code, and that audit results were adequately reviewed by responsible management.

In the case of third-party audits, the NRC inspection team verified that CBIS reviewed and accepted the supplied third-party audit documentation before taking credit for the audit results.

b. Findings Introduction The inspectors identified an unresolved item (URI) associated with the licensees structural model analysis of containment penetrations 44 and 45 (P44/P45).

Specifically, 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, provided subject piping meets the following provisions: Level C service limits of the 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 Code Section III, Level C Service limits not being exceeded. At the time of the inspection, the licensee identified it had not performed structural model calculations for P44/P45 to verify they were meeting their current license bases (CLB). The licensee entered this issue into its corrective action program as CR 50063621 and WEC CAP IR 2020-10571.

Description The inspectors determined a performance deficiency existed associated with 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the licensees failure to have design control measures for verifying or checking the adequacy of the design of containment penetrations 44 and 45. Specifically, the licensee failed to perform a structural model calculation for P44 and P45 to verify the adequacy of the penetrations design in accordance with its CLB.

26 Per IMC 0613, Power Reactor Construction Inspection Reports, this issue will remain unresolved pending further analysis by SNC and Westinghouse, which will be used by the inspectors to determine if the performance deficiency is material to the acceptance criteria of an ITAAC (URI 05200025/2020003-02, ASME Section III Level C Service Limits May Not Be Met for Containment Penetrations 44 and 45).

65001.F-02.01-Design Document Review The inspectors observed concrete placement in the air inlet structure of the shield building cylindrical wall. The inspectors reviewed the placement plan to verify if preplacement planning had been completed to assure quality construction and contingency plans had been made to address unexpected events.

The inspectors reviewed two concrete batch plant delivery tickets to verify if the batched mixes conformed to the placement plan and were discharged in accordance with the construction specification. Additionally, the inspectors observed in-process record testing to verify if concrete temperature, flow, air content, and unit weight conformed to requirements and in-process testing was completed at the proper location and frequency as required by the construction specification.

The inspectors also reviewed placement activities to verify that drop distances did not exceed specification requirements; placement rates were consistent with the placement plan; and appropriate attention was given to areas of obstruction within the modules to minimize the potential for voids or honeycombing.

41 The inspectors reviewed a sample of CRs associated with the steel panels and concrete to verify the evaluations and corrective actions were conducted in accordance with the licensee's CAP; the issues were accurately identified and documented in a timely manner; and the issues were classified and resolved commensurate with their safety significance. The inspectors reviewed the trending codes applied to each CR to verify they were correctly identified, tracked, and trended in accordance with ND-AD-002-025, "Issue Identification, Screening, and Dispatching." The inspectors reviewed a sample of nonconformances associated with the steel panels and concrete to verify the nonconformances had adequate technical evaluations and were dispositioned in accordance with APP-GW-GAP-428, "Nonconformance and Disposition Report."

b. Findings No findings were identified.

65001.02-02.01 - Inspection of Concrete Placement

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

65001.F-02.01-Design Document Review The inspectors observed the reinforcing steel within room 12505, the upper nuclear island nonradioactive ventilation system (VBS) B&D equipment room, at elevation 135-3. This room is located between walls M and P and the shield building cylindrical wall and wall 11. Specifically, the inspectors verified if the material designation, grade, sizes, spacing, lap splices, and general layout of the top and bottom reinforcing bars within the concrete slab on metal deck were consistent with the applicable design drawings, E&DCRs, construction specification SV4-CC01-Z0-31, and ACI 349-01.

The inspectors reviewed two E&DCRs to verify if design changes made to the slab reinforcement were performed in accordance with 10 CFR Part 50 Appendix B, Criterion III, Design Control. Specifically, the inspectors verified if the design changes were subject to control measures commensurate with those applied to the original design and were approved by the organization that performed the original design or the designated responsible organization. The inspectors also reviewed the E&DCR to verify if an adequate technical justification was provided for the design change; deviations from applicable quality standards such as ACI 349-01 were controlled; and the revised design was correctly translated into the updated design output documents.

b. Findings No findings were identified.

65001.F-02.01-Design Document Review

65001.F-02.04-General QA Review The inspectors observed the reinforcing steel in wall P between elevations 135-3 and approximately 146-10. This wall forms the west wall of the upper VBS B&D Equipment Room (Room 12505). Specifically, the inspectors verified if the material designation, grade, sizes, spacing, lap splices, and general layout of the vertical, horizontal, and transverse reinforcing bars within the wall were consistent with the applicable design drawings, E&DCRs, construction specification SV4-CC01-Z0-31, and ACI 349-01.

The inspectors reviewed four E&DCRs to verify if design changes impacting the construction of wall P were performed in accordance with 10 CFR Part 50 Appendix B, Criterion III, Design Control. Specifically, the inspectors verified if the design changes were subject to control measures commensurate with those applied to the original design and were approved by the organization that performed the original design or the designated responsible organization. The inspectors also reviewed the E&DCR to verify if an adequate technical justification was provided for the design change, deviations from applicable quality standards such as ACI 349-01 were controlled, and the revised design was correctly translated into the updated design output documents.

The inspectors reviewed a sample of CRs associated with the steel reinforcement and embedments to verify the evaluations and corrective actions were conducted in accordance with the licensee's CAP; the issues were accurately identified and documented in a timely manner; and the issues were classified and resolved commensurate with their safety significance. The inspectors reviewed the trending codes applied to each CR to verify they were correctly identified, tracked, and trended in accordance with ND-AD-002-025, "Issue Identification, Screening, and Dispatching." The inspectors reviewed a sample of nonconformances associated with the steel reinforcement and embedments to verify the nonconformances had adequate technical evaluations and were dispositioned in accordance with APP-GW-GAP-428, "Nonconformance and Disposition Report." Additionally, the inspectors observed repairs and rework resulting from the nonconformances to verify if they were conducted in accordance with the dispositions.
