SUBJECT:

VOGTLE ELECTRIC GENERATING PLANT, UNITS 3 AND 4 - NRC INTEGRATED INSPECTION REPORTS 05200025/2019004, 05200026/2019004

Dear Mr. Yox:

On December 31, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the Vogtle Electric Generating Plant, Units 3 and 4. The enclosed inspection report documents the inspection results, which the inspectors discussed on January 16, 2020, with Mr. M. Page and Mr. P. Martino, Vogtle 3&4 Plant Managers, and other licensee and contractor staff members.

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

The inspection team also examined a sample of corrective action program (CAP) activities and concluded that the implementation of the CAP and overall performance related to identifying, evaluating, and resolving problems at Vogtle Electric Generating Plant Units 3 and 4 was adequate. Licensee and contractor identified problems were put into the CAP at an appropriate threshold. Problems were prioritized and evaluated proportional to the safety significance of the problems. Corrective actions were reviewed effectively and in a timely manner proportionate with their importance to safety and dealt with the identified causes of problems. Lessons learned from industry construction experience were effectively reviewed and applied when appropriate. Audits and self-assessments were generally used to find problems and appropriate actions. Based on the assessment of safety culture results, interviews done during the inspection, and a review of the employee concerns program, employees appeared to show freedom to raise nuclear safety concerns without fear of reprisal.

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

M. Yox If you contest the violations or significance of these NCVs, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement; and the NRC resident inspector at the VEGP Units 3 and 4.

If you disagree with a cross-cutting aspect assignment in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region II; and the NRC resident inspector at the VEGP Units 3 and 4.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Should you have any questions concerning this letter, please contact us.

Sincerely,

/RA/

SUMMARY

OF FINDINGS Inspection Report (IR) 05200025/2019004, 05200026/2019004; 10/01/2019 through 12/31/2019; Vogtle Unit 3 Combined License, Vogtle Unit 4 Combined License, integrated inspection report.

Integrated Report This report covers a three-month period of inspection by regional and resident inspectors, and announced Inspections, Tests, Analysis, and Acceptance Criteria (ITAAC) inspections and the annual team corrective action program inspection. Two findings of very low safety significance (Green), each with an associated non-cited violation (NCV) of NRC requirements, were identified. The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) which is determined using 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 Inspection Manual Chapter (IMC) 2506, Construction Reactor Oversight Process General Guidance and Basis Document.

Problem Identification and Resolution The inspection team sample selection concluded that the implementation of the Corrective Action Program (CAP) and overall performance related to identifying, evaluating, and resolving problems at Vogtle Electric Generating Plant Units 3 and 4 was conducted in accordance with licensee procedures and quality assurance requirements. Licensee and contractor identified problems were put into the CAP at an appropriate threshold. Problems were prioritized and evaluated proportional to the safety significance of the problems. Corrective actions were reviewed effectively and in a timely manner proportionate with their importance to safety and dealt with the identified causes of problems. Lessons learned from industry construction experience were effectively reviewed and applied when appropriate. Audits and self-assessments were generally used to find problems and appropriate actions. Based on the assessment of safety culture results, interviews done during the inspection, and a review of the employee concerns program, employees appeared to show freedom to raise nuclear safety concerns without fear of reprisal.

A. NRC-Identified and Self Revealed Findings (Green) The inspectors identified an ITAAC finding of very low safety significance (Green) with an associated NCV of 10 Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion IV, Procurement Document Control, for the licensees failure to specify an accurate conversion factor for calculating the dry film density of coatings used in containment. Specifically, the licensee used a conversion factor that was rounded in a non-conservative manner, which resulted in the dry film density not meeting the ITAAC. The licensee entered this issue into its corrective action program as CR 50034350 and CR 50034649. The licensee performed immediate corrective actions to demonstrate with reasonable assurance the nonconforming coatings with a dry film density of 99.83 pounds per cubic feet (lbs/ft3) would not transport to the containment sump screens and the design function of the PXS would not be impaired.

M. Yox The performance deficiency was of more than minor safety significance, and thus a finding, because it was material to the acceptance criteria of an ITAAC. The inspectors determined this finding was not associated with a security program; it was not associated with an IMC 2504 operational or construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. The inspectors determined this finding was of very low safety significance (Green) because the licensee was able to demonstrate with reasonable assurance that the design function of the applicable structure or system would not be impaired by the deficiency. 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. Specifically, the licensee failed to use decision making practices that emphasized prudent choices over those that are simply allowable when rounding off conversion factors in specifications, and when receiving coatings that were within less than 0.25% of the acceptance criterion. [H.14] (Section 1A06)

(Green) The inspectors identified an ITAAC finding of very low safety significance with an associated NCV of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to install Unit 3 core makeup tank (CMT) A upper level sensing lines for instruments PXS 11A/C and 13 B/D in accordance with ITAAC 2.2.03.08c.xii and the approved design requirements. The licensee entered this finding into its corrective action program for evaluation and identification of appropriate corrective actions (CR 50034981). Corrective actions for this issue included rework on the two-level sensing lines to correct the nonconforming conditions.

The performance deficiency was of more than minor safety significance, and thus a finding, because it was material to the acceptance criteria of an ITAAC and invalidated the Inspection, Test, or Analysis described in the ITAAC. The inspectors determined this finding was not associated with a security program; it was not associated with an IMC 2504 operational/construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. The inspectors determined this finding was a performance deficiency of very low safety significance (Green) because if left uncorrected, the finding could reasonably be expected to impair the design function of only one train of a multi-train system. The inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Avoiding Complacency, in the area of Human Performance, in accordance with Appendix F of IMC 0613. Specifically, the licensee failed to properly implement appropriate error reduction tools, such as inadequate verification by personnel performing the measurements. [H.12] (Section 1A07)

B. Licensee-Identified Violations None.

M. Yox REPORT DETAILS Summary of Plant Construction Status Unit 3: The licensee set the shield building conical roof steel framing and was completing the shield building construction. In the containment building, the licensee continued with installation of reactor coolant system (RCS) and passive core cooling system (PXS) instrumentation, electrical conduits and cables (safety and non-safety related (NSR)) and commenced the ASME required hydrostatic testing of major PXS components. The licensee was nearing the end of the construction of the auxiliary building structure. Major electrical and instrumentation equipment, in the auxiliary building and the main control room (MCR), have been installed and termination of cables was ongoing.

Unit 4: The licensee continued with shield building construction. In the containment building, the licensee continued construction on the operating deck frame work and was completing installation of RCS and PXS large bore piping. The licensee continued construction of the auxiliary building structure from elevation 117-foot () 6-inch () to 160 and routing of electrical raceways.

65001.03-02.06 - Nondestructive Examination (NDE)

65001.B-02.01 - Program and Procedures Review

65001.B-02.04 - Production Controls

65001.B-02.05 - Inspection The inspectors reviewed design and work control documents associated with PCI Energy Services (PCI) using the electrical discharge machining (EDM) process for an internal modification on the downstream edge radius contour of the branch nozzle for the stage 4 automatic depressurization system (ADS) connection to the Unit 3 reactor coolant system (RCS) Loop 2 hot leg (Line L001B). This modification was required to address flow induced vibrations. Specifically, the inspectors reviewed quality assurance (QA) documents to verify if the EDM qualification and field activities were conducted in accordance with the approved design and requirements of the ASME Code Sections III and XI.

M. Yox The inspectors reviewed the instructions and qualification test procedure for the EDM process, that applies to both Units 3 & 4, for the removal of three test coupons from a simulated Type 316LN stainless steel branch nozzle mock-up to verify if the equipment and PCI technicians/operators were monitored using established hold point sign-offs by QA/quality control (QC) inspectors in accordance with PCI's QA program and IWA-4460. The inspectors reviewed the following hold point associated activities:

signing of the EDM operation parameter data sheet by the PCI technicians/operators to document controls were within established limits;

thermally impacted surfaces of all three test coupons were examined at 10X magnification for evidence of cracks;

two of the test coupons surfaces were ground, and polished surfaces were tested for grain size and ASTM A 262-Practice E corrosion sensitization;

contour measurements using physical go/no-go templates at established azimuth marker locations to verify surfaces were within tolerances;

surface finish roughness determination for maximum 125 micro-inch root mean square (RMS) using a comparator gauge;

final nondestructive visual examinations (VT) and liquid penetrant examinations (PT) by NDE-VT/PT examiners; and

laser scanning inspection to determine wall thickness of the modified ADS-4 branch nozzle mock-up.

The inspectors reviewed the PCI Quality Assurance Traveler 914262-001 used to control field activities for the Vogtle Unit 3 ADS-4 branch nozzle modification to verify if the design and inspection requirements were met with QA/QC and applicable Authorized Nuclear Inspector (ANI) hold points signed-off in accordance with PCI's QA program for each of the following final critical steps of the EDM operation:

use of deionized water;

alignment of the EDM head;

rough cuts and contouring measurements using physical go/no-go templates at designated location markers;

surface blending and polishing for surface roughness measurements using a comparator by an NDE Level II QC technician;

NDE-PT in accordance with ASME Section III, NB-2546, by NDE Level II Examiner; and

metrology laser scanning inspection for measuring wall thicknesses at several locations of the branch nozzle.

The inspectors reviewed the PCI/ Westinghouse Electric Company (WEC) final report 914262-RPT-005 methodology and results for the analysis using the as-built laser scan of the Unit 3 ADS-4 branch nozzle modification measurements to verify if the final dimensions were within tolerances, overall modification matched design, and azimuth locations passed the visual inspection with the physical go/no-go templates.

b. Findings No findings were identified.

M. Yox 1A02 (Unit 3) ITAAC Number 2.2.01.02a (91) / Family 06F

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

65001.03-02.06 - Nondestructive Examination (NDE)

65001.B-02.05 - Inspection The inspectors reviewed NDE for three Chicago Bridge and Iron (CB&I) Laurens fabricated welds on the spent fuel pool (SFS) suction and discharge lines between containment and valves SFS-PL-V035 and SFS-PL-V038, respectively. Specifically, the inspectors visually inspected weld numbers SV3-SFS-PLW-511-1, SV3-SFS-PLW-511-6, and SV3-SFS-PLW-521-1 on 6-inch diameter schedule 40S stainless steel pipe in line numbers L035 and L038 to verify there were no unacceptable lack of fusion, undercut, porosity, or cracks. Additionally, the inspectors reviewed the radiographic examination reports and the associated film for all three welds to determine whether the techniques, geometric unsharpness, density, and image quality indicator sensitivity were within allowable limits and met the requirements of American Society of Mechanical Engineers (ASME) Code Section V, Article 2. The inspectors also reviewed the radiographic film to verify the welds were free of rejectable indications as required by the acceptance criteria listed in ASME Code Section III, Article NC-5000.

b. Findings No findings were identified.

1A03 (Unit 3) ITAAC Number 2.2.01.08 (109) / Family 08F (Unit 4) ITAAC Number 2.2.01.08 (109) / Family 08F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.01.08 (109). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.08-02.04 - Inspection of Containment Electrical Penetration Assemblies (EPAs)

65001.08-02.05 - Inspection of Station Grounding and Surge Protection The inspectors performed a review of design documents, test records, studies and engineering analysis associated with containment EPAs protection from high currents to determine if the design protected the cable through the penetration from currents exceeding the thermal limits of the penetration.

M. Yox The inspectors reviewed Class 1E DC and UPS System (IDS) system breaker coordination studies for electrical penetration to verify if the design incorporated adequate fuse sizes to ensure protection from high currents. Specifically, the inspectors verified loads and fuse protection applied to the cables through the penetrations were within the ratings indicated by the manufacturer damage curves.

The inspectors reviewed the rating/capacity to operate motor operated valves and other components inside containment which were fed from distribution panels and motor control centers protected by fuses sized to supply their loads. The inspectors performed this review to verify if the fuse rating would withstand fault currents for the time required to clear possible anticipated circuit faults as designed.

b. Findings No findings were identified.

1A04 (Unit 3) ITAAC Number 2.2.01.08 (109) / Family 08F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.01.08 (109). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.08-02.02 - In-Process Installation

65001.08-02.04 - Inspection of Containment Electrical Penetration Assemblies (EPAs)

65001.F-02.04 - General QA Review The inspectors reviewed equipment preservation check records of EPAs 12, 14, 16, 28, and 30 to determine whether the records showed that either the acceptance criteria for humidity, temperature, and nitrogen pressure were met or the record was referred to engineering for disposition in accordance with the Bechtel Project Nuclear Quality Control Manual (PNQCM).

The inspectors observed a sample of cable terminations for EPAs 6 and 31 in the auxiliary building to determine whether they were installed in accordance with the instructions and drawings in the work package. Specifically, the inspectors observed the in-process work to verify splices were performed in accordance with splice kit instructions in the work packages; the cables were sized in accordance with the drawings in the work package; the crimp type connectors were sized for the cables being spliced; and the crimper had been calibrated.

b. Findings No findings were identified.

1A05 (Unit 3) ITAAC Number 2.2.03.08c.vi.03 (191) / Family 06A

a. Inspection Scope

M. Yox The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.03.08c.vi.03 (191). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.A - As-Built Attributes for SSCs associated with ITAAC

65001.A.02.03 - Independent Assessment/Measurement Inspection The inspectors performed an inspection to verify the Unit 3 in-containment refueling water storage tank (IRWST) calculated volume was greater than 73,100 cubic feet between the tank outlet connection and the tank overflow as specified in Table 2.2.3-4 of Appendix C of the Vogtle Unit 3 Combined License (COL). The inspectors observed the licensee survey selected portions of the inside of the IRWST; reviewed approved drawings for the IRWST and its internal structures and components; reviewed the design calculation for the IRWST's volume; compared the survey results with dimensions from the drawings and the design calculation; and reviewed the licensees determination of the IRWST's volume based on the survey results. The inspectors also took independent measurements to validate inputs to the licensee's determination of the IRWST calculated volume.

b. Findings No findings were identified.

1A06 (Unit 3) ITAAC Number 2.2.03.08c.x (195) / Family 14F (Unit 4) ITAAC Number 2.2.03.08c.x (195) / Family 14F

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.03.08c.x (195). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.14-02.01 - General Installation

65001.14-02.03 - Testing and Verification

65001.F-02.01 - Design Document Review

65001.F-02.02 - Fabrication Records Review

65001.F-02.04 - General QA Review The inspectors reviewed documents and observed application activities for Service Level (SL) I and II coatings and materials, used inside the containment, associated with ITAAC 2.2.03.08c.x (195). ITAAC 2.2.03.08c.x verifies that buildup of debris from potentially failed coatings and materials (e.g. caulk, fire barrier and ventilation filters, tags, signs, etc.) located inside containment, would be minimal and potential transport to the sump screens would be prevented. This inspection focused on the review of the following material transport aspects, as required by this ITAAC.

M. Yox For in-containment coatings and materials applied on site, the inspectors interviewed personnel and reviewed records to determine if the applied coatings and materials met the ITAAC acceptance criteria, applicable quality standards, and the Updated Final Safety Analysis Report (UFSAR) commitments. Specifically, the inspectors:

reviewed the unqualified coating log to verify nonconforming coatings that cannot be qualified as SL I were evaluated, on a case-by-case basis, relative to impact on plant safety as described in Section 6.1.2 of the UFSAR;

interviewed personnel and reviewed a sample of the procurement and design change documents to determine if touch-ups or applications for inorganic zinc coatings were controlled per the licensees quality control procedures for SL I coatings;

reviewed a sample of purchase orders, receipt inspection reports, procedures, specifications, test reports, and certificates of conformance to determine if the approved SL II coatings met the density requirement of greater than or equal to 100 pounds per cubic foot (lbs/ft3);

walked down Unit 3 and 4 containment buildings to verify if the applied coatings, signs and tags would not inhibit safety systems functions as described in the UFSAR, and to determine if there were other materials that could be transported to the sump but were not included in the safety analysis;

observed coating operations, coatings storeroom, surface preparation areas, and coating application booths to determine if quality controls were placed on coating activities and materials;

reviewed procurement and receipt inspection documents for a sample of coating and additive batches from the storeroom, to verify that the associated QA records were retrievable, and that these documented a coating density of greater than or equal to 100 (lbs/ft3); and

reviewed a sample of qualification records for applicators and QC inspectors to verify if coatings activities were done by qualified individuals as per the licensees quality program requirements.

For in-containment coatings and materials installed on a structures, systems, and components (SSC) by a vendor (i.e., coating applied prior to receipt inspection), the inspectors reviewed purchase orders, vendors qualifications and coatings work process documents, and receipt inspection reports to verify if the coatings and materials met the ITAAC acceptance criteria, applicable quality standards, and the UFSAR commitments. Specifically, the inspectors:

reviewed procedures and records for the installation of fire barriers (i.e. high-density silicone elastomer) in penetrations to verify that the materials were tested and found to have a density greater than or equal to 100 (lbs/ft3), as required by the ITAAC acceptance criterion;

reviewed procurement documentation and records associated with tags and signs to verify that the signs and tags were manufactured by vendors on the approved vendors list (ASL), and found to have a density greater than or equal to 100 (lbs/ft3), as required by the ITAAC acceptance criterion;

reviewed the licensee's approved specification for moisture barrier seals (i.e.

caulking) that would be used to procure caulking for moisture barriers inside containment to determine if it required that the density be greater than or equal to 100 (lbs/ft3) as required by the ITAAC acceptance criteria and 10 Code of

M. Yox Federal Regulations (CFR) Part 50 Appendix B Criterion IV which states, in part, that requirements for materials be passed down to suppliers in specifications;

reviewed coating records from the Quality Assurance Data Packages (QADPs),

associated with commodity codes SS30 (i.e. reactor pressure vessel (RPV) supports) and MH01 (i.e. polar crane), to determine if batches of paint used on SS30 and MH01 had an associated certified testing record that determined a dry film density greater than or equal to 100 (lbs/ft3); and

reviewed a sample of audit reports for a vendor associated with coating activities to verify that audits documented the placement or retention of the contractor on the ASL, were done by qualified auditors, and audit findings were documented and dispositioned.

b. Findings Introduction The inspectors identified an ITAAC finding of very low safety significance (Green) with an associated NCV of 10 CFR Part 50, Appendix B, Criterion IV, Procurement Document Control, for the licensees failure to specify an accurate conversion factor for calculating the dry film density of coatings used in containment. Specifically, the licensee used a conversion factor that was rounded in a non-conservative manner, which resulted in the dry film density not meeting the ITAAC.

Description During the NRC inspection of ITAAC 2.2.03.08c.x conducted November 12 to 21, 2019, the inspectors identified the licensees coatings specification used an incorrect non-conservative conversion factor to calculate the dry film density of coatings to be used in containment. The ITAAC requires coatings used on containment surfaces to have a dry film density of 100 pounds per cubic feet (lbs/ft3), or if a coating is used with a lower dry film density a report must exist and conclude the coating will not transport to the containment sump screen. The inspectors found coatings specification APP-G1-X0-001, "Protective Coatings Design Requirements," Revision 8, required calculation of the dry film density using 7.5 as the conversion factor from gallons to cubic feet. The correct conversion factor should have been 7.48. This resulted in non-conservative rounding in dry film density calculations for coatings applied in containment. A review of the coatings density records found one batch had been used inside containment that had an actual dry film density of 99.83 lbs/ft3 without a report to support its use. The licensee entered this issue into the corrective action program as CR 50034350 and CR 50034649 for evaluation and identification of appropriate corrective actions.

Analysis The licensees failure to use an accurate conversion factor in the coatings specification was a performance deficiency. Criterion IV, Procurement Document Control, of 10 CFR Part 50 Appendix B, requires in part that requirements which are necessary to assure quality are suitably included or referenced in the documents of procurement of

M. Yox material. The licensee failed to meet this requirement by procuring coatings with a specification that did not include requirements for using correct conversions from gallons to cubic feet and resulted in material that was purchased and used that did not meet the AP1000 design requirements. This performance deficiency was screened as more than minor in accordance with Manual Chapter 0613 Appendix E, "Examples of Minor Construction Issues." The inspectors determined this performance deficiency was of more than minor safety significance, and thus a finding, because it was material to the acceptance criteria of an ITAAC. The acceptance criterion of ITAAC number 2.2.03.08c.x requires, in part, that a report exist and concludes that the coatings used on these surfaces have a dry film density of 100 lbs/ft3. If a coating is used that has a lower dry film density, a report must exist and conclude that the coating will not transport. Contrary to the above, the licensee procured and subsequently installed the coatings inside containment with a density of 99.83 lbs/ft3, without a report to support its use.

The inspectors determined this finding was associated with the Material Control attribute of the Procurement/Fabrication Cornerstone. The finding was not associated with a security program; it was not associated with an IMC 2504 operational or construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. In accordance with IMC 2519, "Construction Significance Determination Process," Appendix A, "AP 1000 Construction Significance Determination Process, dated December 6, 2017, the inspectors determined the finding was associated with the PXS system which is assigned to the high risk importance column of the AP1000 Construction Significance Determination Matrix,"

dated December 6, 2017. The inspectors determined this finding was of very low safety significance (Green) because the licensee was able to demonstrate with reasonable assurance that the design function of the applicable structure or system would not be impaired by the deficiency (Step 7.a.2 of Appendix A, IMC 2519).

In accordance with IMC 0613, Appendix F, "Construction Cross-Cutting Areas and Aspects," dated October 1, 2018, 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. Specifically, the licensee failed to use decision making practices that emphasized prudent choices over those that are simply allowable when rounding off conversion factors in specifications, and when receiving coatings that were within less than 0.25% of the acceptance criterion.

[H.14]

Enforcement 10 CFR Part 50 Appendix B, Criterion IV, Procurement Document Control, requires, in part, that "measures shall be established to assure that applicable regulatory requirements, design bases, and other requirements which are necessary to assure quality are suitably included or referenced in the documents for procurement of material, equipment, and services, whether purchased by the applicant or by its contractors or subcontractors."

M. Yox Contrary to the above, prior to November 12, 2019, the licensee failed to assure that applicable requirements were included in documents for procurement of material.

Specifically, specification APP-G1-X0-0001 was sent to suppliers to procure coatings that stated: Calculate the dry film unit weight, also referred to as dry film density, using the following expression: Unit weight (lbs/ft3 dry) = 7.5 Wg (Sw/Sv), which assumes that one cubic foot equals 7.5 gallons rather than 7.48 gallons. The failure to include accurate conversion factor in procurement documentation resulted in coatings that were procured, received, and installed in containment that had an actual dry film density that was less than 100 lbs/ft3. The licensee performed immediate corrective actions to demonstrate with reasonable assurance that the nonconforming coatings with a dry film density of 99.83 lbs/ft3 would not transport to the containment sump screens and the design function of the PXS would not be impaired. The licensee entered this issue into its corrective action program as CRs 50034350 and 50034649.

Because this violation was not repetitive or willful, was of very low safety significance, 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 05200025/2019004-02 and 05200026/2019004-02, Non-Conservative Rounding of Conversion Factor Used in Formula for Calculating Density of Protective Coatings).

1A07 (Unit 3) ITAAC Number 2.2.03.08c.xii (197) / Family 03A

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.2.03.08c.xii (197). The inspectors used the following NRC IPs/sections to perform this inspection:

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 The inspectors performed an as-built inspection of the Unit 3 CMT upper level sensing lines for both CMTs to verify the ITAAC. The inspectors performed a walkdown of the CMT level sensing lines for CMT level sensors PXS11A/B/D/C, 12A/B/C/D, 13A/B/C/D, and 14A/B/C/D with the licensee, observed the licensee perform surveys of the level sensing lines, and performed an independent assessment to verify the as-built piping was consistent with the approved design requirements. In addition, the inspectors reviewed quality records including the Principal Closure Document (PCD),

design drawings, and survey results to determine whether the upper level sensing lines for the CMTs had a minimum downward slope of 2.4 degrees from the centerline of the connection to the CMT to the centerline of the connection to the standpipe as specified in Table 2.2.3-4 of Appendix C of the Vogtle Unit 3 COL.

b. Findings Introduction

M. Yox The inspectors identified an ITAAC finding of very low safety significance (Green) with an associated NCV of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to install Unit 3 CMT A upper level sensing lines for instruments PXS 11A/C and 13 B/D in accordance with ITAAC 2.2.03.08c.xii and the approved design requirements.

Description On November 20, 2019, the inspectors performed an as-built inspection of the Unit 3 CMT upper level sensing lines for both CMTs associated with CMT level sensors PXS 11A/B/D/C, 12A/B/C/D, 13A/B/C/D, and 14A/B/C/D to verify ITAAC2.2.03.08c.xii.

The ITAAC required the upper level sensing lines for the CMTs to have a minimum downward slope of 2.4 degrees from the centerline of the connection to the CMT to the centerline of the connection to the standpipe. The inspectors performed a walkdown of the CMT upper level sensing lines with the licensee and observed the licensee reperform slope measurements after the licensee had already completed and verified the acceptance criteria. Absent this walkdown and additional measurements taken for the inspectors, the licensee had completed its inspection and was prepared to submit its 10 CFR 52.99(c)(1) completion notification. During the inspection, the inspectors identified two upper level sensing lines (one on each of two CMT A level sensors) did not meet the minimum slope requirement. Line SV3-PXS-205 on PXS 11A/C did not meet the minimum slope requirement along the 19-inch section of pipe. The as-built measurement taken was 2.1 degrees. The previous measurement taken by the licensee on November 16, showed the slope of this pipe section was in conformance with the ITAAC at 2.8 degrees. Line SV3-PXS-335 on PXS 13B/D did not meet the minimum slope requirement along the 12-1/16 inch section of pipe. The as-built measurement taken was 2.3 degrees. The previous measurement taken by the licensee on November 15, showed the slope of this pipe section was in conformance with the ITAAC at 2.8 degrees.

The inspectors reviewed the design requirements for installation of the CMT level instruments and noted the minimum slope requirement was included in two design instructions that provided installation requirements for the CMT level instruments.

Design change proposal (DCP) APP-GW-GEE-4516, "Redesign the CMT Level Instrument Layout due to Overstress in Instrument Related Pipe and Nozzles of the Tap Lines," Revision 1.0, and E&DCR APP-PXS-GEF-276, "CMT Level Instrument Tap Piping Tolerances," Revision 0, both contained the minimum slope requirement.

Additionally, the inspectors noted the design drawings for each of the CMT level instrument taps contained a note specifying the minimum slope requirement.

Drawings APP-PXS-PLW-205, "Passive Core Cooling System Containment Bldg.

Room 11400 CMT A Lvl Instrument Tap LT011A/C," Revision 3, and APP-PXS-PLW-335, "Passive Core Cooling System Containment Bldg. Room 11300 CMT A Lvl Instrument Tap LT013B/D," Revision 3, were issued for the Unit 3 CMT A upper level sensing lines for instruments PXS 11A/C and 13 B/D, respectively.

The licensee entered this issue into its corrective action program as CR 50034981 for evaluation and identification of appropriate corrective actions and performed in-field rework on the two level sensing lines which included cutting the sensing welds, correcting the slope of the lines, and rewelding the sensor lines, to correct the nonconforming conditions.

M. Yox On December 10, the inspectors observed the licensee reperform the as-built inspection of the Unit 3 CMT upper level sensing lines for all four CMT A level sensors (i.e., PXS 11A/B/D/C and 13A/B/C/D) to verify the ITAAC was satisfied after the rework.

Analysis The licensee's failure to perform Unit 3 CMT sensor installation activities in accordance with ITAAC 2.2.03.08c.xii and approved design requirements was a performance deficiency. The inspectors determined that the licensee failed to perform activities that affected quality, in accordance with 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," and specified in APP-GW-GEE-4516, APP-PXS-GEF-276, APP-PXS-PLW-205, and APP-PXS-PLW-335 to ensure the Unit 3 CMT A upper level sensing lines for instruments PXS 11A/C and 13 B/D met minimum requirements of 2.4 degree slope. This performance deficiency was screened as more than minor in accordance with Manual Chapter 0613 Appendix E. The inspectors determined this performance deficiency was of more than minor safety significance, thus a finding, because it was material to the acceptance criteria of an ITAAC and invalidated the Inspection, Test, or Analysis described in the ITAAC. Specifically, the acceptance criteria for ITAAC 2.2.03.08c.xii states: "Each upper level tap line has a downward slope of greater than or equal to () 2.4 degrees from the centerline of the connection to the CMT to the centerline of the connection to the standpipe." 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 performance deficiency was not minor because substantial rework 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 two level sensing lines during its quality inspection and the performance deficiency was not minor because the components were rendered unacceptable and corrective action was required to bring them into conformance.

The inspectors determined this finding was related to the Construction/Installation attribute of the Construction Reactor Safety Cornerstone. The inspectors determined this finding was not associated with a security program; it was not associated with an IMC 2504 operational/construction program; and it was not associated with a repetitive, NRC-identified omission of a program critical attribute. In accordance with Appendix A of IMC 2519, the inspectors determined that the finding associated with the PXS (CMT) system which is assigned to the intermediate risk importance column of the AP1000 Construction Significance Determination Matrix." The inspectors determined this finding was a performance deficiency of very low safety significance (Green) because if left uncorrected, the finding could reasonably be expected to impair the design function of only one train of a multi-train system (Step 11.a of Appendix A, IMC 2519).

In accordance with IMC 0613, Appendix F, the inspectors determined the finding was indicative of present licensee performance and was associated with the cross-cutting aspect of Avoiding Complacency, in the area of Human Performance.

M. Yox Specifically, the licensee failed to properly implement appropriate error reduction tools, such as inadequate verification by personnel performing the measurements. [H.12]

Enforcement 10 CFR 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 be accomplished in accordance with these instructions, procedures, or drawings.

Contrary to the above, on November 20, 2019, the licensee failed to install Unit 3 CMT A upper level sensing lines for instruments PXS 11A/C and 13 B/D in accordance with ITAAC 2.2.03.08c.xii and the approved design requirements specified in APP-GW-GEE-4516, APP-PXS-GEF-276, APP-PXS-PLW-205, and APP-PXS-PLW-335. The licensee entered this finding into its corrective action program for evaluation and identification of appropriate corrective actions (CR 50034981). Corrective actions for this issue included rework on the two level sensing lines to correct the nonconforming conditions. Because this violation was not repetitive or willful, was of very low safety significance, and was entered into the licensee's corrective action program, it is being treated as an NCV, consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2019004-01, Failure to Meet ITAAC for Installation of CMT Level Sensing Lines).

1A08 (Unit 3) ITAAC Number 2.5.02.08b.i (542) / Family 10A

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.5.02.08b.i (542). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.10-02.02.c - As Built Verification The inspectors performed an as-built inspection of the Unit 3 protection and safety monitoring system (PMS) PMS main control room (MCR)/remote shutdown workstation transfer panel to verify the ITAAC. The inspectors performed a post-installation field inspection of the transfer panel with the licensee and reviewed quality records including the PCD and design drawings to determine whether separate transfer switches existed for each safety-related division and the nonsafety-related control capability as specified in Table 2.5.2-8 of Appendix C of the Vogtle Unit 3 COL.

b. Findings No findings were identified.

1A09 (Unit 3) ITAAC Number 2.5.02.11 (550) / Family 10F

a. Inspection Scope

M. Yox The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.5.02.11 (550). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.F-02.04 - General QA Review The inspectors observed the handling and transport of Divisions A, B, and D PMS cabinets between the 100 and 117 elevations to verify the cabinets were appropriately rigged and handled in accordance with the vendor technical manual and protected from damage and obstructions during transport. The inspectors also performed walkdowns of the areas where the cabinets were to be installed and verified the areas were being controlled in accordance with Nuclear Quality Assurance (NQA)-

1 Level B storage requirements for temperature and humidity. In addition, the inspectors observed the final placement and welding of PMS cabinets to verify the cabinets were oriented and installed in their correct locations and in accordance with the weld specifications. The inspectors verified the weld rod materials were listed on the welding procedure specification (WPS). The inspectors verified the field welds were the correct length, size, spacing, and applied in the correct locations in accordance with design drawings.

The inspectors observed welding of multiple shims using fillet welds to the base of two electrical cabinets and adjoining floor embedment plates at several locations to verify if the shims were installed in accordance with drawing 10112D20 and American Welding Society (AWS) Code D1.1:2000 for the PMS. The inspectors reviewed two Bechtel welding inspection checklist entries for 17 fillet welds to determine if QC inspection hold points were signed-off and dated for preheat, fit-up, interpass temperature, and final visual inspections in accordance with the requirements of AWS D1.1, Clauses 5 and 6. The inspectors also reviewed the checklist entries against the rod tickets to determine if the traceability of the welder and welding electrodes were controlled in accordance with work package SV3-PMS-JDW-1023214. The inspectors reviewed WPS P1-A-Lh (using supporting PQR-1310) to verify if the welding procedure was qualified and certified in accordance with the requirements of ASME Section IX, Article II. The inspectors reviewed the certified material test report (CMTR) for 3/32" diameter E7018 electrodes with lot-no. 1408A and material issue code S024 to verify if the chemical analysis and mechanical properties were in accordance with the requirements of ASME Section II-Part C, SFA-5.1. The inspectors reviewed the performance qualification record of welder EL141 to determine if he/she was tested and certified in accordance with the requirements of the ASME Code,Section IX, Article III. The inspectors reviewed visual examination procedure VT-AWS D1.1 to verify if it was written in accordance with the requirements of AWS D1.1, Clause 6.

The inspectors also reviewed the Certificate of Qualification for Level II QC welding inspector "JL" and the visual acuity and color contrast examination record to verify if the individual was qualified with current annual vision examination in accordance with the requirements of AWS D1.1, Clause 6.1.4.

b. Findings No findings were identified.

M. Yox (Unit 4) ITAAC Number 2.6.03.04b (602) / Family 08E

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.6.03.04b (602). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.08-02.06 - Testing and Verification

65001.E-02.04-Documentation The inspectors performed a review of design documents, test records, studies and engineering analysis associated with ITAAC Number 2.6.03.04b (602) design inspection.

The inspectors used the NRC inspection procedure (IP) 65001.08 to verify that the electrical components were rated (e.g., voltage, current, interrupting, current withstand, type, size, material, etc.) consistent with the results of the analysis and calculations reviewed. In addition, the inspectors reviewed applicable electrical design calculations (e.g., voltage drop calculations, AC and DC load studies, short circuit calculation, and coordination studies.)

The inspectors focused their review on Class 1E components including:

battery chargers,

batteries,

inverters,

regulating transformers,

DC distribution panels,

DC motor control centers,

Class 1E uninterruptible power supply system (IDS) distribution systems circuit breakers and fuses, and

IDS distribution systems branch wiring and feeder conductors.

Under ITAAC 2.6.03.04b (602), the inspectors reviewed a sample of calculations for the analysis of the main AC power system (ECS) (non-1E) and IDS (1E) design basis (e.g. short circuit, grounds, etc.) to determine if the associated short circuit, fault currents and grounds were correctly designed and integrated throughout the AC and DC electrical distribution systems.

The inspectors reviewed samples of the associated coordination study for the IDS to verify that short circuit and fault currents were adequately applied and that electrical equipment such as circuit breakers and fuses were adequately coordinated. In addition, the inspectors reviewed the electrical design specifications and design reports associated with the ECS (non-1E) and IDS (1E) to determine if the requirements for short circuit, grounds, coordination, etc. were identified and implemented in accordance with UFSAR sections 8.3.1 and 8.3.2 and Institute of Electrical and Electronic Engineers (IEEE) 323 (1974), IEEE 141 (1993), and IEEE 242 (1986) standards.

M. Yox The inspectors also reviewed the revised electrical calculations identified in NRC inspection report, Westinghouse/WECTEC Report No. 99901467/2016-201.

Specifically, the inspectors reviewed samples of these revised design calculations to verify that the inspection results associated with the IDS Coordination Studies and Degraded Grid Voltage to Regulating Transformers calculations previously reviewed under vendor inspection 99901467/2016-201 were still adequate.

b. Findings No findings were identified.

1A11 (Unit 3) ITAAC Number 2.6.03.04j (876) / Family 08E (Unit 3) ITAAC Number 2.6.03.04j (876) / Family 08E

a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.6.03.04j (876). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.08 - Inspection of ITAAC-Related Installation of Electric Components and Systems

65001.E-02.01 - Design Basis Requirements

65001.E-02.03 - Qualification

65001.E-02.04 - Documentation The inspectors reviewed test records, wiring diagrams, and other applicable documentation to verify the acceptance criteria of the ITAAC was met and to verify the design and installation of the battery monitor fuse isolation panels would prevent credible faults from propagating into the Class 1E portions of the IDS. Specifically, the inspectors reviewed test reports APP-IDS-VTR-001, APP-IDS-VTR-002, APP-IDS-VTR-003, and APP-IDS-VTR-004 to verify if qualification test records identified critical characteristics of isolation barriers for maximum credible fault currents. The inspectors verified if the reports documented results that verified fuses were installed as double fuse isolation between Class 1E and non-Class 1E and interrupted the faults applied without physical damage to the barrier components. The inspectors also noted that the report identified that isolation barriers were able to withstand applied faults without signs of degradation. The inspectors reviewed a condition report and qualification records to verify that testing and reconciliation was performed for the electrical isolation components between the battery monitors and the battery banks.

b. Findings No findings were identified.

1A12 (Unit 3) ITAAC Number 2.6.03.07 (616) / Family 08F (Unit 4) ITAAC Number 2.6.03.07 (616) / Family 08F

M. Yox a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.6.03.07 (616). The inspectors used the following NRC IPs/sections to perform this inspection:

65001.08-02.02 - In-Process Installation

65001.F-02.01 - Design Document Review The inspectors performed a review of design documents, test records, studies and engineering analysis associated with ITAAC Number 2.6.03.07 (616) Breakers and Fuses Supplying Loads.

The inspectors used NRC IP 65001.08 to verify that the electrical components were rated (e.g., voltage, current, withstand/interrupting current, type, size, material, etc.)

consistent with the results of the analysis and calculations reviewed. In addition, the inspectors reviewed applicable electrical design calculations (e.g., voltage drop calculations, AC and DC load studies, short circuit calculation, and coordination studies).

The inspectors focused their review on Class 1E components including:

battery chargers,

batteries,

inverters,

regulating transformers,

DC distribution panels,

DC motor control centers,

IDS distribution systems circuit breakers and fuses, and

IDS distribution systems branch wiring and feeder conductors.

Under ITAAC 2.6.03.07 (616), the inspectors reviewed samples of the IDS system load calculations and coordination studies to verify that DC battery fuses, battery charger circuit breakers, distribution panel fuses, circuit breakers, motor control center fuses and circuit breakers were sized to supply their respective loads and were rated to withstand fault currents for the time required to clear possible anticipated circuit faults.

The inspectors performed walkdowns of the following IDS equipment; battery charger SV3-IDSC-DC-1, IDS switchboard SV3-IDSC-DS-1, inverter SV3-IDSC-DU-2, motor control center SV3-IDSC-DK-1, distribution panels SV3-IDSC-EA-1, SV3-IDSC-EA-2, and SV3-IDSC-EA-3, to verify that the affixed manufacturers nameplate data which defines parameters, such as fault current, voltage, and continuous current ratings, matched those specified in the design documents listed in the document reviewed section of this report.

M. Yox The inspectors reviewed SV3-IDS-E8-001, "Class 1E DC and UPS System Specification Document," Revision 5 and SV3-IDS-E0C-004, "IDS Power Cable Sizing and Voltage Drop Analysis," Revision 5 to determine if the cable rating for the following IDS components met the acceptance criteria of this ITAAC to withstand associated fault currents: Class 1E 250 V DC batteries, Class 1E battery chargers, Class 1E DC switchboards, Class 1E DC motor control centers (MCCs), and Class 1E 250 V DC distribution panels.

The inspectors reviewed the cable rating for each component in Division B of the IDS from Appendix B of SV3-IDS-E8-001, with the voltage drop analysis connection list from Attachment A-1 of SV3-IDS-E0C-004, to determine if the cable sizing and number of conductor(s) requirements were correctly analyzed in accordance with National Fire Protection Association (NFPA) 70, National Electrical Code (NEC), 1999 and was adequate to withstand the associated fault currents. The inspectors also reviewed the listed conductor sizing and number of cables in the voltage drop analysis connection list from Attachment A-1 of SV3-IDS-E0C-004 and compared those with drawings SV3-IDS-E3-002, SV3-IDS-E3-003, SV3-IDS-E3-006, SV3-IDS-E3-007, and SV3-IDS-E3-012 to verify the cable sizing and number of conductors was translated to the drawings correctly.

The inspectors reviewed Class 1E DC and UPS system specifications and Class 1E (IDS) 250V DC system coordination study to determine if the fuse and circuit breaker sizing for the following IDS components met the acceptance criteria of this ITAAC for exceeding their analyzed load requirements: Class 1E 250 V DC batteries, Class 1E battery chargers, Class 1E DC switchboards, Class 1E DC MCCs, and Class 1E 250 V DC distribution panels.

Specifically, the inspectors reviewed the fuse sizing for each component in Division B of the Class 1E DC and UPS system coordination study outlined in SV3-IDS-E0C-011 to determine if the load requirements were correctly analyzed. The inspectors also reviewed the fuse sizing in Section 5.0 of SV3-IDS-E0C-011 and compared those with drawings SV3-IDS-E3-002, SV3-IDS-E3-003, SV3-IDS-E4-006, SV3-IDS-E3-007, and SV3-IDS-E3-012, to verify the fuse sizing was translated to the drawings correctly.

The inspectors reviewed specifications for Class 1E MCCs to determine if the fuse sizing was adequate for the associated loads fed from the MCCs. Specifically, the inspectors reviewed the APP-IDSB-DK-1 (Division B MCC) listed load Locked Rotor Amperes (LRA) and Full Load Amperes (FLA) against the listed fuse size in Appendix F of SV3-DK01-Z0-010 to determine if the associated components could perform their intended safety functions and to determine if the loads would momentarily (approximately 1 second) experience the full LRA and would not cause their associated fuses to exceed the melt limit before reaching their continuous FLA. The inspectors reviewed calculation APP-IDS-E0C-015, "IDS MCC PWER FUSE RG1.106 Compliance," Revision 0 to determine if the following LRA and fuse sizing would allow the components to perform their intended safety function:

LRA 151A at fuse rating 125 ampere(A),

LRA 362A at fuse rating 200A, and

LRA 382A at fuse rating 200A.

M. Yox The inspectors reviewed design specifications, coordination studies, and drawings to determine if the power buses for the following components could withstand the associated short circuit current experienced in the IDS: Class 1E DC switchboards, Class 1E inverters, Class 1E DC MCCs, and Class 1E 250 V DC distribution panels.

Specifically, the inspectors reviewed the worst-case short circuit available current on Division B of the IDS from the battery sizing calculations against design specifications for Class 1E 250 VDC IDS switchboards, inverters, static transfer and manual bypass switches, MCCs, distribution panels, and Class 1E fuse panels, to determine if the components were sized to withstand the short circuit current. The inspectors also reviewed drawings of system One Line Meter & Relay Diagrams to verify that withstand currents on the associated power busses were translated to the drawings correctly.

Notice of Nonconformance (NON) 99901467/2016-201-01 was documented in NRC inspection report 99901467/2016-201 (ADAMS Accession No.: ML17013A658). This was an ITAAC Finding for the licensee's failure (through the contractor) to identify and verify the adequacy of circuit breaker and fuse interrupting current ratings as a critical characteristic, as part of its commercial grade dedication process. During this inspection, the inspectors reviewed testing of fuses and circuit breakers and fuse interrupting current ratings, which were defined as critical characteristics in its commercial grade dedication process. The inspectors reviewed EMPE-EV-97-APP, "Westinghouse Isolation Barrier Maximum Credible Fault Test Report" to verify that Class 1E to non-Class 1E isolation barriers met applicable requirements from IEEE 384-1981 associated with maximum credible faults for IDS components including circuit breakers and fuses installed in battery chargers, DC distribution panels, and MCC circuits were rated to interrupt available fault currents.

The inspectors verified if the testing met applicable requirements associated with maximum credible faults as directed by the EMPE-ATP-42, "Isolation Barrier IEEE Standard 384-1981 Fault Test Plan." The testing was performed at the KEMA Powertest LLC. in Chalfont, Pennsylvania under Westinghouse CDI-4815, Commercial Dedication Instruction Fault Testing Services AC & DC Short Circuit Withstand, which credited the KEMA Powertest ISO/IEC 17025 accreditation. As a result, Non-conformance 99901467/2016-201-01 identified in the respective vendor inspection report is considered closed.

NRC vendor inspection report 99901467/2016-201, noted that "complete coordination between the protective devices within the bus was not achieved for the situation of an impedance fault". The inspectors discussed this item with Westinghouse representatives during the IDS design inspection. Westinghouse identified a high impedance fault within a panel to be caused by a loose connection of cable connections or of the buswork itself. It was not believed that this was credible for class 1E equipment due to crediting the quality process in this equipment through the commercial dedication process. This (commercial dedication) process inherently revisits connections specifically for items such as torque/ tightness and to ensure connectors/ connections are of a high integrity (i.e. no stripped connectors/ threaded holes). The inspectors verified that the equipment under review was qualified to include design basis seismic events (DBE and SSE) and the connections and workmanship (both of the equipment and connections to the equipment) were controlled by NQA-1 processes. Consequently, the type of conditions that would produce high impedance faults was not applicable for this IDS equipment.

1P02 Construction QA Criterion 16 - Annual Team Inspection (IP 35007, Appendix 16)

.1 Assessment of the Corrective Action Program Effectiveness

a. Inspection Scope The inspectors reviewed the licensee's CAP to determine if:

the licensee had effectively implemented its approved quality assurance program as required by 10 CFR Part 50, Appendix B, Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants;

the licensee clearly defined the interface requirements for implementing the CAP to its contractors, Westinghouse and Bechtel; and

the delegation was allowed by the licensees QAPD, Section 16, Corrective Action, and details outlined in the services agreement and interface documents. The inspection scope therefore included a review of the CAP interface between the licensee and its contractors.

The inspectors reviewed implementing procedures and documents from the licensee and its contractors for the identification, evaluation, and resolution of conditions adverse to quality to determine if they met Section 16 of the licensee's QAPD, Basic Requirement 16 of NQA-1, and Section 17.5 Quality Assurance Program Description of the UFSAR.

The inspectors reviewed the CAP implementing procedures to determine if they established: thresholds for problem identification; requirements for the effectiveness of immediate and preventative corrective actions; the accuracy and thoroughness of problem documentation; and the adequacy of corrective actions for previously identified compliance issues.

M. Yox The program review scope included an evaluation of the following CAP performance attributes to verify if they were addressed in the CAP programs:

classification, prioritization, and evaluation for reportability of conditions adverse to quality (CAQs);

identification of problems in a timely manner fitting with their significance and ease of discovery;

screening of items entered into the CAP to determine the proper level of evaluation;

finding and fixing procurement program problems;

finding and fixing design errors;

considerations for extent of conditions, generic implications, common causes, and previous occurrences as appropriate;

classification and prioritization of the resolution of problems fitting the safety significance;

for significant conditions adverse to quality (SCAQs), identification of root and contributing causes, as well as actions to prevent recurrence;

identification of corrective actions focused to fix the problem;

completing corrective actions in a timely manner proportional to the safety significance of the issue (including the use of interim corrective actions to minimize the problem and/or mitigate its effects until permanent actions can be done);

provisions for escalating corrective actions that are not adequate or timely to higher management;

overview of trends in CAQs;

coverage to include important non-safety related structures, systems, and components; and

evaluation of operating experience information.

The inspectors reviewed a sample of CAP issues closed since the last CAP inspection (August 2018) to determine if the program procedures were properly implemented. The issues chosen included a diverse sample across the licensee and contractors' programs. The inspectors sampled issues related to CAQs and issues that had been determined to not be CAQs to determine if:

conditions adverse to quality were found and fixed in required time frames per procedures;

classification and prioritization of the resolution of each problem was proportionate with its safety significance and at the appropriate threshold;

conditions were screened upon entry into the CAP to determine the proper level of evaluation;

proper consideration was given to extent of conditions, generic implications, common causes, and previous occurrences;

the corrective actions were focused to ensure the problems were fixed;

the licensee and its contractors evaluated and reported conditions per 10 CFR 50.55(e) and 10 CFR 21;

the identification and correction of design deficiencies were being adequately addressed;

M. Yox

extent of conditions were adequately addressed and appropriate corrective actions were developed and done; and

the evaluations properly considered the escalation of issues to higher management if the corrective actions were not adequate or timely.

The inspectors reviewed the procedures and a sample of issues from the licensee and contractors observation, trending, and metrics programs to determine if the licensee was identifying CAQs and transferring those issues to the respective CAP program.

The inspectors reviewed a sample of recent trend reports and metrics to determine if:

the trend reports were issued within the time frames given in procedures;

the trend reports and metrics had information and analyses of licensee and contractor performance improvement activities; and

CAP inputs were generated for adverse trends or recommendations as required by program procedures.

The inspection scope included an evaluation of the handling of issues introduced into the CAPs from sources such as: self-assessments and audits, NRC generic communications, and operating and construction experience.

The inspectors evaluated the processing of CAP entries to determine if the following qualities were considered: risk, safety significance, consequence of malfunctions, complexity of design and fabrication, needs for special controls or surveillance over activities, the degree to which functional compliance could be shown by inspection or test, the quality history and degree of standardization of items, and the difficulty of repair or replacement.

The inspectors reviewed a sample of N&Ds that document non-conforming conditions to determine if:

the reports correctly and clearly identified the nonconformances (NCRs);

the N&Ds and NCRs were adequately initiated, processed, reviewed, dispositioned, and closed in accordance with the QA program implementing procedures for the control of nonconforming material, parts, and components;

N&Ds and NCRs were appropriately screened and trended for non-hardware related CAQs;

reportability screening and evaluations under 10 CFR Part 21 and 10 CFR 50.55(e) were performed;

applicability to project documents, records, and ITAAC was properly identified and documented;

affected organizations were notified of the status of nonconforming items;

the dispositions were properly identified and documented;

there was adequate written technical justification for the acceptance of a nonconforming item, dispositioned repair, or use-as-is;

nonconformances dispositioned use-as-is or repair were subjected to design control measures commensurate with those applied to the original design; and

M. Yox

repaired or reworked items were re-examined in accordance with applicable procedures and with the original acceptance criteria unless the disposition had established alternate acceptance criteria.

b. Assessment Assessment - Effectiveness of Problem Identification The inspectors determined, based on the sample of issues reviewed, that issues were being effectively identified. The samples reviewed indicated that issues were identified in a timely manner; they were described clearly; and a systematic screening process ensured that issues were appropriately entered into the CAP.

Assessment - Effectiveness of Prioritization and Evaluation of Issues Based on the sample of issues reviewed, the inspectors determined that the licensee was adequately evaluating and prioritizing issues. The reviewed sample of issues were screened by appropriate levels of management and they were assigned levels corresponding to their significance. No SCAQs were reviewed as none had been closed during the last 12 months.

Assessment - Effectiveness of Corrective Actions The inspectors determined that in the selected sample, corrective actions for identified deficiencies were timely, adequate, and proportional to their safety significance. Problems found by apparent cause investigations were handled per the licensees CAP procedures.

c. Findings No findings were identified.

.2 Assessment Use of Construction Experience

a. Inspection Scope The inspectors reviewed the licensee's experience database and CAP to determine if items that were classified as applicable to the site were entered into the CAP as specified by their construction experience program procedure ND-AD-VNP-004. The inspectors reviewed the licensee's experience database to determine if it added NRC related information, such as NRC Regulatory Issues Summaries and Information Notices. The inspectors reviewed a sample of CAP documents to determine if disposition and handling of applicable industry experience items met the construction experience program procedure.

b. Assessment Based on the inspection activities described, the inspectors determined that the licensee adequately identified construction and operating experience; adequately screened and evaluated these experiences for applicability to the project; and entered issues into their CAP program for tracking and handling.

M. Yox c. Findings No findings were identified.

.3 Assessment of Self-Assessments and Audits

a. Inspection Scope The inspectors reviewed a sample of documented audits, and a CAP self-assessment. The review was performed to determine whether the oversight of the CAP by the licensee was sufficient to verify the health of the program and to identify areas for improvement as needed. The inspectors also compared the results of the audits and self-assessment to the results of the inspection to determine if there were any discrepancies between the results of the inspection and the licensees conclusions.

b. Assessment The inspectors determined that the conduct of audits and self-assessments by the licensee was accomplished in accordance with the established plans. Corrective actions to address the identified issues were generally prioritized, evaluated, and completed within applicable procedural requirements.

c. Findings No findings were identified.

.4 Assessment of Safety Conscious Work Environment

a. Inspection Scope The inspectors conducted a review to provide insight into whether a safety conscious work environment (SCWE) was being maintained at the site. The inspectors assessed the sites Employee Concerns Program (ECP) effectiveness and evaluated management oversight of the corrective action process including anonymous CAP entries. These reviews were used to determine if construction personnel were willing to report safety issues via the different avenues available (CAP, ECP, management, etc.).

The team performed the following activities:

conducted interviews;

reviewed the ECP work instructions;

reviewed various ECP case files and Work Environment Assessments (WEA); and

performed a walk-down of the ECP and CAP drop boxes and office locations.

M. Yox The inspectors observed activities involving licensee personnel and interviewed some construction staff to identify issues that may represent challenges to the free flow of information, such as areas where employees may be reluctant to raise concerns. The inspectors reviewed the ECP work instructions and interviewed ECP personnel to understand the current health and challenges of the sites SCWE as assessed by the ECP office. The licensees ECP procedures and files were reviewed to determine if:

procedures were adequate to implement a site ECP;

files contained adequate documentation;

issues were entered and reviewed in a timely manner;

concerns were adequately addressed;

corrective actions were tracked; and

individuals were provided feedback.

ECP WEAs were reviewed to determine if identified issues were addressed and actions to prevent recurrence were put in place.

b. Assessment Based on this review, the NRC found no evidence to indicate that there are challenges to the construction organizations SCWE. The ECP was effective in evaluating concerns that were reviewed during this inspection. Anonymous CAP entries reviewed by the inspectors were determined to be properly investigated and dispositioned. Overall, individuals were willing to raise safety concerns without fear of retaliation.

c. Findings No findings were identified.
