SUMMARY

OF FINDINGS

Inspection Report (IR) 05200025/2021007, 05200026/2021007; 10/0 1/2021 through 12/31/2021; Vogtle Units 3 and 4 Combined License, Integrated I nspection Report.

This report covers a three-month period of inspection by region al and resident inspectors. One construction finding of very low safety significance (Green) wi th an associated noncited violation (NCV) in the Construction Installation Cornerstone was identifi ed. 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, Const ruction Significance Determination Process. Cross-cutting aspects are determined us ing IMC 0613, Appendix F, Construction Cross-Cutting Areas and Aspects. All violations o f NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy. The NRCs program for overseeing the safe construction of commercial nuclear power re actors is described in IMC 2506, Construction Reactor Oversight Process General Guidance a nd Basis Document.

A. NRC-Identified and Self Revealed Findings

(Green) A construction finding of very low safety significance with an associated NCV of Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion XVI, Corrective Action, was identified for the licensees failure to identify and correct conditions adverse to quality pertaining to Institute of Electrical and Electronic En gineers 384-1981 cable separation issues inside Class 1E dc and uninterruptible power supply syst em (IDS) regulating transformer panel SV3-IDSC-DT-1. The licensee failed to maintain the 1-inc h separation required for safety and nonsafety-related cables within IDS C regulating transfor mer panel SV3-IDSC-DT-1 in accordance with electrical installation specification APP-G1-V8 -001, Appendix B2, Separation and Segregation Spacing Requirements. Two conditions were ide ntified. The licensee entered this finding into its corrective action program as condition re port 50117479. Corrective actions for this issue included rework to restore compliance with the s eparation requirements and the initiation of a causal analysis.

The performance deficiency was of more than minor safety signif icance, and thus a finding, because it represented an adverse condition that rendered the q uality of the safety function associated with IDS unacceptable or indeterminate and required substantive corrective action.

The inspectors determined this finding was a performance defici ency of very low safety significance because if left uncorrected it could reasonably be expected to impair the design function of IDS for only one train of a multi-train system. Th e inspectors determined the finding was indicative of present licensee performance and was associat ed with the cross-cutting aspect of Work Management, in the area of Human Performance. T he licensee failed to implement a process of planning, controlling, and executing wor k activities such that nuclear safety was the overriding priority. Specifically, the licensee failed to have a process in place for quality control to verify all cable separation nonconformances were addressed inside the panel.

[H.5] (Section 1P01)

B. Licensee-Identified Violations

None.

1A08 (Unit 3) ITAAC Number 3.3.00.02a.i.d (763) / Family 01F

a. Inspection Scope

The inspectors performed a direct inspection of construction ac tivities associated with ITAAC Number 3.3.00.02a.i.d (763). The inspectors used the fol lowing NRC IPs/sections to perform this inspection:

65001.01 - Inspection of ITAAC-Related Foundations & Buildings

65001.01-02.07 - Identification and Resolution of Problem

65001.02-02.07 - Problem Identification and Resolution

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

65001.A.02.04 - Review As-built Deviations/Nonconformance

The inspectors reviewed the CA20 module as-built summary repor t along with those portions of the nuclear island basemat and auxiliary building a s-built summary reports applicable to the radiologically controlled area of the auxilia ry building to verify if the reports document that the acceptance criteria of ITAAC 3.3.00.0 2a.i.d were met.

Specifically, the inspectors rev iewed the reports to verify if the reports reconciled deviations during construction, including Table 3.3-1 wall and floor thicknesses, and concludes that the as-built radiologically controlled area of t he auxiliary building

9 including the critical sections, conform to the approved design and will withstand the design basis loads specified in the Design Description without loss of structural integrity or the safety-related (SR) functions, and without impacting com pliance with the radiation protection licensing basis.

The inspectors verified if the as-built summary reports address ed deviations to the standard plant issued after the effective date of the as-design ed summary reports as well as, unit-specific deviations.

The inspectors reviewed Table 3-2 of the CA20 module as-built s ummary report and Tables 3-2, 3-3, 3-4, and 3-5 of the auxiliary building as-buil t summary report to verify if margin existed in the structural components and connections aft er reconciliation of deviations to the standard plant issued after the effective dat e of the as-designed summary reports and site specific nonconformance and dispositio n reports (N&Ds) and E&DCRs.

Additionally, the inspectors reviewed Tables 4-1 and 4-2 of the CA20 module and auxiliary building as-built summa ry reports, respectively, to d etermine if the as-built construction met the concrete wall thicknesses and radiation sh ielding requirements of Vogtle 3 and 4 UFSAR Table 3.3-1 and any localized deviations f rom UFSAR Table 3.3.-1 were evaluated and reconciled to the approved design.

b. Findings

No findings were identified.

1A09 (Unit 3) ITAAC Number 3.3.00.02a.i.d (763) / Family 01F

a. Inspection Scope

The inspectors performed a review of the licensees corrective actions associated with noncited violation (NCV)05200025/2021006-01, Failure to Follo w Procedure BGEN-ITPA-004, documented in Inspection Report 05200025/2021006 (ML 21314A277). The review was to determine whether the corrective actions taken by the licensee were complete and sufficient to address the issue and ensure the acc eptance criteria for the related ITAAC could be met. Specifically, this violation was a ssociated with the licensees failure to follow its procedural guidance for troubl eshooting external leakage from the Unit 3 spent fuel pool (SFP) and fuel transfer canal ( FTC). The performance deficiency resulted in over-pressurization of the leak chases a nd adjacent floor liner plates within the SFP and FTC, causing damage to the floor line r plates and structural module wall face plates near the leak chases. Corrective actio ns for this issue included repairs to the SFP and FTC liner, the leak chase, and the surro unding structural modules to return them into conformance with the design. The v iolation represented an ITAAC finding because it was material to the acceptance criteri a of ITAAC 3.3.00.02a.i.d (763) and prevented the licensee from meeting an ITAAC Design Commitment.

The inspectors reviewed N&D SV3-CA20-GNR-001091 and associated corrective actions taken to address this issue to verify that the nonconfo rming conditions were appropriately evaluated, approved, and dispositioned in accorda nce with applicable technical and QA requirements. The inspectors observed welding and reviewed

10 documents for replacing all floor liner plates at the bottom of the SFP to verify welding and inspection activities performed by PCI Energy Services (PCI ) were performed in accordance with the requirements of the Westinghouse Electric C orporation (WEC) specification APP-GW-Z0-105 and American Welding Society (AWS) D1.6:1999 Structural Welding Code for Stainless Steel.

The inspectors reviewed certified material test reports (CMTR) of the new duplex stainless steel floor liner plates and weld filler metals to ve rify chemical analysis and mechanical properties were in accordance with the requirements of AWS D1.6, Clause 1 - General Provisions.

The inspectors reviewed welding procedure specifications (WPSs) for machine and manual gas tungsten arc welding (GTAW) with supporting procedur e qualification records (PQR) to verify testing and certifications were perform ed and maintained in accordance with AWS D1.6, Clause 4 - Qualification.

The inspectors reviewed performance qualification records of we lding operators and welders with maintenance logs to verify testing and certificati ons were performed and maintained in accordance with AWS D1.6, Clause 4 - Qualificatio n.

The inspectors observed partial plasma arc cutting of the origi nal floor weld joint T-shaped backing bars and end-caps that were located inside the l eak chases to verify removal of obstructions interfering with the new weld joint rec tangular backing bars. On occasions, the inspectors observed vacuum cleaning before insta llation of the new wider floor liner plates to verify cleanliness was maintained t o prevent compromising the effectiveness of the SFP leak chase detection system.

The inspectors reviewed surface base metal repair records and l iquid penetrant examinations performed on the north face of the SFP wall to ver ify the following were in accordance with AWS D1.6, Subclause 5.13 - Base Metal Repairs b y Welding for SR systems:

a) Traceability of weld filler metals and manual welders; and b) Established quality control (QC) inspection hold points were signed-off for:

initial visual (VT) and liquid penetrant (PT) inspections of ex cavated areas;

preheat and cleanliness prior to start of welding;

VT and PT of completed repair welds; and

final ultrasonic thickness testing (UTT) measurements.

The inspectors reviewed PCI final PT and UTT inspection reports to verify the north wall surface base metal repair examinations and final thickness measurements were performed with acceptable results in accordance with AWS D1.6, Clause 6 - Inspection

The inspectors reviewed PCI QC inspector records to verify annu al visual acuity examinations and Level II certifications for VT, PT, and digita l UTT were maintained at the time of examinations in accordance with the guidelines of t he American Society of Nondestructive Testing (ASNT) Recommended Practice SNT-TC-1A "P ersonnel Qualification and Certification in Nondestructive Testing" and AWS D1.6, Clause 6 -

The inspectors performed a walkdown of the correcti ve actions taken inside of the Class 1E dc and uninterruptible power supply syst em (IDS) C regulating transformer panel SV3-IDSC-DT-1.

b. Findings

Introduction

NRC inspectors identified a cons truction finding of very low safety significance (Green) and an associated NCV of 10 CFR, Part 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to identify and correct con ditions adverse to quality pertaining to IEEE 384 cable separation issues inside IDS regul ating transformer panel SV3-IDSC-DT-1.

20 Description

During an NRC panel cable separation inspection on October 20, 2021, the inspectors identified that IDS C regulating transformer panel SV3-IDSC-D T-1 did not maintain the 1-inch separation required for SR and nonsafety-related (NSR) c ables as stated in electrical installation specification APP-G1-V8-001, Appendix B 2, Separation and Segregation Spacing Requirements. The following two condition s were identified:

1. NSR cable DT1CXN utilizes a vendor supplied wireway which contained SR cables. CR 50111736 states that this condition was detected du ring the original extent of condition inspection for the panel in CR 501 04589 but was inadvertently left out of the CR.

2. Separation was not maintained between NSR vendor jumpers t hat are permanently installed and field installed SR wiring SV3-IDSC-EW -EA2CXC.

This condition was identified in CR 50104589 but not adequately corrected since the corrective actions taken resulted in a similar violat ion with the same vendor jumpers and another conductor of SV3-IDSC-EWEA2CXC.

The licensee entered these issues into their corrective action program (CAP) as CR 50117479.

Analysis

The inspectors determined the failure to identify and correct conditions adverse to quality pertaining to IEEE 384-1981 cable separation issues ins ide IDS regulating transformer panel SV3-IDSC-DT-1 was a performance deficiency (P D). The PD was determined to be more than minor because if left uncorrected, the PD represented an adverse condition that rendered the quality of the safety funct ion associated with IDS unacceptable or indeterminate and required substantive correcti ve action. Specifically, the failure to maintain physical separation between SR and NSR cables inside IDS C regulating transformer panel SV3-IDSC-DT-1 rendered the capabil ity of the regulating transformer to provide electrical isolation between the NSR mai n AC power system and SR Class 1E 250 VDC circuits and the SR Class 1E uninterruptibl e power supply circuits indeterminate in the event of a single failure on the NSR cable. This violation was determined to be a construction finding.

The inspectors determined the finding was associated with the C onstruction/Installation cornerstone of the Construction Reactor Safety strategic perfor mance area. The inspectors assessed the finding using IMC 2519, Appendix A, AP 1000 Significance Determination Process, dated October 26, 2020, and 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 wit h a repetitive, NRC-identified omission of a program critical attribute. The findi ng was of very low safety significance (Green) because the finding was associated with th e IDS system and if left uncorrected it could reasonably be expected to impair the desig n function of only one train of a multi-train system.

In accordance with IMC 0613, Appendix F, Construction Cross-Cut ting Areas and Aspects, the inspectors determined the finding had a cross-cut ting aspect of Work Management, in the area of Human Performance, because the licen see failed to implement a process of planning, controlling, and executing wor k activities such that

21 nuclear safety was the overriding priority. Specifically, the licensee failed to have a process in place for QC to verify all cable separation nonconfo rmances were addressed inside the panel. [H.5]

Enforcement

10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requires in part, that measures be established to assure that conditions adverse to qu ality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected.

Contrary to above, on October 20, 2021, the licensee did not id entify and correct conditions adverse to quality pertaining to IEEE 384 cable separation issues inside IDS regulating transformer panels SV3-IDSC-DT-1. Specifically, NSR cable DT1CXN was routed in a vendor supplied wireway which contained SR cables. This condition was not identified in CR 50104589, which was initiated to capture n onconformances during the performance of IEEE 384 separation extent of condition. Ad ditionally, separation was not maintained between permanently installed NSR vendor jum pers and field installed SR wiring SV3-IDSC-EW-EA2CXC. This condition was ide ntified in CR 50104589 but not adequately corrected since the corrective acti ons taken resulted in the same vendor jumpers not being adequately separated from ano ther conductor of SV3-IDSC-EWEA2CXC. This finding did not present an immediate s afety concern because the plant was not operating, and the reactor vessel did not have fuel in it. The licensee entered this issue into its CAP as CR 50117479. Becau se this violation was not repetitive or willful, was of very low safety significance, and was entered into the licensees CAP, this violation is being treated as an NCV consi stent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05200025/2021007-01, Failure to Correct Cable Separation issues in panel SV3-IDSC-DT-1).

The inspectors reviewed these documents and procedures to assess the correctiv e actions for completeness, appropriate priority level, applicable preventive measures, and adequacy in addressing the causes and extent of condition, including gen eric implications, common cause, and previous occurrences.

The inspectors performed walkdowns of the onsite M&TE calibrati on facility to verify M&TE had been calibrated, identified, handled, stored, and main tained at prescribed calibration intervals prior to use. The inspectors observed ha ndling and storage of calibrated M&TE standards to verify they were handled with care and stored in their original cases to maintain accuracy. The inspectors observed c alibration of M&TE to verify they were calibrated before their due dates, in a contro lled environment, using calibrated traceable standards and an approved procedure by a q ualified M&TE quality control engineer (QCE). The inspectors reviewed sample calibra tion records to verify they included the as-found and as-left conditions, accuracy req uirements, tolerances, calibration results, calibration dates, calibration procedure, and calibration standard used. In addition, the inspectors observed storage of M&TE to verify the M&TE QCE segregated, documented, and evaluated when M&TE was found out o f calibration, out of tolerance, lost, or out of service.

The inspectors performed a walkdown of the Units 3 and 4 M&TE s atellite distribution facilities to verify the M&TE check-in/check-out process was co ntrolled by authorized personnel who utilized the M&TE tracking database. The inspect ors reviewed M&TE issue receipts to verify the M&TE issued was within the calibra tion due date and the tolerance range for use. The inspectors reviewed M&TE return r eceipts to verify the M&TE returned were the ones issued and were returned in a timel y manner in accordance with the requirements of 26139-000-4MP-T81C-N7102, Control of Measuring and Test Equipment, procedure. The inspectors revie wed M&TE issued to WPs that were not returned by their M&TE calibration due dates to verify CRs were initiated and dispositioned in a timely manner under the licens ees CAP. In addition, the inspectors interviewed the M&TE QCE lead responsible for notify ing construction supervisors for return of M&TE within their calibration due dat e. The inspectors reviewed the notifications and verified they contained lists of M&TE with associated calibration due dates sent to construction supervisors.

24 The inspectors reviewed and evaluated the licensees M&TE track ing database to verify it was maintained by authorized personnel and controlled the is suance of M&TE in accordance with 26139-000-4MP-T81C-N7102 procedure. The inspec tors reviewed M&TE released to a WP to verify the tracking database and calib ration records indicated the M&TE had been calibrated at prescribed intervals and, if th e interval was adjusted a technical justification was provided for a change in calibratio n frequency. The inspectors reviewed the calibration records to verify the M&TE were calibr ated using known industry standards to verify they had the accuracy, stability, range, and resolution required for the items being calibrated. The inspectors also s elected M&TE whose accuracy was found to be suspect or out of tolerance to verify OCRs were initiated and appropriate corrective action was recommended for repair, repla cement, or re-calibration to bring the M&TE to within their specified accuracy and tolera nce range of use. The inspectors reviewed calibration records for M&TE that were cons istently found out of calibration during re-calibration to verify repairs or replacem ent of the M&TE was performed in accordance with quality control instruction 26139-2QI-Q07C-N7102, Control of Measuring and Test Equipment. The inspectors inte rviewed calibration personnel to verify their role was understood and met procedure requirements for maintaining the tracking database. In addition, the inspectors reviewed qualification and training records to verify QCEs were trained to conduct the cal ibrations and interviewed on-site calibration lab supervisors to verify they understood t he potential impact of M&TE to the ITAAC acceptance criteria.

The inspectors selected M&TE from the tracking database that wa s recently taken out of service because of a nonconforming condition, including being o ut of calibration, lost, or damaged. The inspectors reviewed OCRs for M&TE that were out o f calibration, lost, broken, or out of tolerance to verify reports had been processe d and evaluated in a timely manner to minimize a backlog. The inspectors verified i n each instance a CR was initiated and evaluated in a timely manner to evaluate previous use of the M&TE. The inspectors verified the licensee either documented an evaluatio n or was planning on performing an evaluation to address the validity of previous in spections, tests, and status determinations performed since the last calibration in conjunct ion with the corrective actions. The inspectors reviewed CRs to verify short term corr ective actions were effective and the QA process was being followed for processing nonconforming M&TE.

The inspectors verified M&TE discrepancies documented in the CA P were appropriately addressed with respect to ITAAC completion. The inspectors ver ified CRs that could impact ITAAC acceptance criteria were assigned an ITAAC event c ode so the CRs could be appropriately tracked, and corrective actions implemented.

The inspectors verified a process was in place for evaluating O CRs and their impact to ITAAC. Specifically, the inspecto rs reviewed OCRs from the backlog M&TE database associated with ITAACs to verify the licensee evaluated whether M&TE discrepancies impacted completion of the ITAAC. This review included OCRs fo r those ITAACs where the licensee determined M&TE did not impact completion of the I TAAC and those ITAACs where this determination had not yet been made. The inspectors review included whether the licensee appropriately determined if use of the M&TE was as sociated with an ITAAC.

The inspectors reviewed completed ITAAC closure notifications ( ICNs) where the ITAAC acceptance criteria depended on the use of calibrated M&TE. Th e review included the verification that any M&TE used was calibrated. In addition, t he inspectors interviewed ITAAC project manager, ITAAC engineers, field closure engineers, Bechtel supervisors and M&TE QCE to verify nonconforming M&TE were appropriately ev aluated in the OCRs for any impact to ITAACs.

25 On June 25, 2021, the licensee made a 10 CFR 50.55(e) notificat ion to the NRCs Headquarters Operations Center (Event Notification 55328) regar ding electrical construction and M&TE control at Vogtle Units 3 and 4. The NRC was also notified in a letter, ND-21-0603, Southern Nuclear Operating Company Vogtle Electric Generating Plant Units 3 and 4 Submittal of 10 CFR 50.55(e) Report Regardi ng Electrical Construction and Measuring & Test Equipment Control (ADAMS Acc ession No.

ML21176A200). The licensee determined that the nonconformances related to IEEE 384-1981 cable separation and seismic/structural provisions for the SR cable raceway systems, including M&TE nonconfor mances, met the criteria of a significant breakdown in the QA program.

In accordance with IMC 0613, Power Reactor Construction Inspec tion Reports, dated November 4, 2020, Construction Deficiency Report (CDR) 05200025 and 05200026/ND-21-0603, was opened by the NRC, to track closure of Southern Nu clear Operating Companys (SNCs) 10 CFR 50.55(e) notification ND-21-0063 Elec trical Construction and Measuring & Test Equipment Control. The cable separation issues were inspected, and results were documented in inspection reports 05200025/2021 010, 05200026/2021010 (ML21236A057) and inspection report 05200025/ 2021011 (ML21312A412).

This report documents the inspection of the M&TE issue of the C DR. The inspectors found one PD during review of the OCRs, where the inspectors id entified a failure to assess a lost multimeter used in two work orders. The PD resul ted in a minor violation of NRC regulatory requirements.

10 CFR Part 50, Appendix B Criterion V, Instructions, procedur es and Drawings states in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumsta nces and shall be accomplished in accordance with these instructions, procedures, or drawings.

Contrary to the above, on December 17, 2021, SNC failed to perf orm activities that affected quality in accordance with Section 6.6, On-Site-Calib ration, of 26139-000-4MP-T81C-N7102, Control of Measur ing and Test Equipment, Revision 5, when performing evaluation of an out-of-calibration condition of a M &TE. Specifically, the licensee evaluated the impact of the M&TE against an incorrect work order and failed to assess the impact of the lost M&TE in two work orders for which the M&TE was used.

When this was identified, the licensee assessed the impact of t he lost multimeter on the two work orders and determined there was no impact to the work performed. Because this PD is non-repetitive, had no safety significance nor any c onsequence, in that, it did not leave any quality process or construction activity indeterm inate or unacceptable the PD was identified as a minor violation. The minor violation wa s not associated with ITAAC. This issue has been captured in the CAP as CR 50118356.

As a result of the inspection results, CDR 05200025 and 0520002 6/ND-21-0603 is closed.

.2 (Closed) NCV 05200025/2021005-03, Failure to Demonstrate Qualif ication of Valve Nonmetallic Parts

The inspectors performed a document review of the licensees co rrective actions for NCV 05200025/2021005-03, Failure to Demonstrate Qualification of Valve Nonmetallic Parts, which was documented in NRC Inspection Repo rt 05200025/2021005, 05200026/2021005 (ML21314A277). The review w as to determine whether the corrective actions taken by the licensee were sufficient to address the issue and to verify the acceptance criteria for the related ITAAC could be met. The violation was associated with the licensees failure to demonstrate that certain valves would be able to perform their design basis func tion for their qualified life duration.

The violation represented an ITAAC finding because it was mater ial to the acceptance criteria of ITAAC 2.2.04.05a.i (226) and 2.1.02.05a.i (19), in that, if left uncorrected, the licensee may not have been able to demonstrate the acceptan ce criteria of the ITAAC was met. The acceptance criteria of this ITAAC requires that the components listed in Tables 2.2.4-1 and 2.1.2-1 can withstand the environm ental conditions that would exist before, during, and after a design basis accident w ithout loss of safety function for the time required to perform the safety function.

The inspectors reviewed E&DCR SV0-PV00-GEF-014 to verify enviro nmental qualification program changes to define and document the qualif ied life analysis for nonmetallic valve parts, specifically for Viton seals used in t he PV64, PV67, and PV70 valve assemblies. The qualified life analysis concluded the Vi ton seals used in the PV64 and PV67 valve assemblies can perform the safety function until they are replaced with the valve actuator. The qualified life analysis concluded the Viton seals used in the PV70 valve assemblies will need to be replaced on a shorter timeframe than the actuator to ensure the safety function can be performe d. As a result, the preventative maintenance program for the Viton seals used in th e PV70 valve assemblies will be revised to ensure replacement occurs on the shorter timeframe.

The E&DCR approved adding the qualified life analysis of the Vi ton seals to the following environmental qualification program documents:

APP-PV64-VBR-011, Revision 0

APP-PV64-VBR-012, Revision 0

APP-PV67-VBR-011, Revision 0

APP-PV67-VBR-012, Revision 0

APP-PV70-VBR-002, Revision 1

APP-PV70-VBR-003, Revision 1

APP-PV70-VBR-004, Revision 1

APP-PV70-VBR-005, Revision 1

Based on the review described above, the inspectors determined the licensee took corrective actions to address the violation and the potential i mpacts to the ITAAC have been appropriately addressed such that the acceptance criteria of ITAAC 2.2.04.05a.i (226) and 2.1.02.05a.i (19) can be met. NCV 05200025/2021005-0 3 is closed.

.3 (Closed) NCV 05200025/2021005-04, Failure to Demonstrate Qualif ication of Containment High Radiation Monitor Door Gasket

The inspectors performed a document review of the licensees co rrective actions for NCV 05200025/2021005-04, Failure to Demonstrate Qualification of Containment High Radiation Monitor Door Gasket, which was documented in NR C Inspection Report 05200025/2021005, 05200026/2021005 (ML21314A277). The r eview was to determine whether the corrective actions taken by the licensee were sufficient to address the issue and to verify the acceptance criteria for the related ITAAC could be met. The violation was associated with the licensees failure to consider the known potential failure modes (aging) of the containment high range r adiation monitor (CHRM) door gasket to determine its qualified life, which can h ave an effect on its functional capability.

The violation represented an ITAAC finding because it was mater ial to the acceptance criteria of ITAAC 3.5.00.01.i (823), in that, if left uncorrect ed, the licensee may not have been able to demonstrate the acceptance criteria of the IT AAC was met. The acceptance criteria of this ITAAC requires, in part, that a rep ort exists and concludes that SR Class 1E components listed in Tables 3.5-1 as being in a harsh environment can withstand the environmental conditions that would exist bef ore, during, and after a design basis accident without loss of safety function for the t ime required to perform the safety function.

The inspectors reviewed E&DCR A PP-RMS-GEF-026 to verify environ mental qualification program changes to define and document the qualif ied life analysis for the CHRM door gaskets would satisfy the above ITAAC acceptance crit eria. The licensee determined the door gasket was present throughout the CHRM hars h environment testing and a qualified life could be established through analy sis. The qualified life analysis concluded the door gasket was qualified for the full s ixty-year life of the CHRM. The E&DCR approved adding the justification for the qual ification to the following environmental qualification program documents:

APP-RMS-VBR-001, Revision 0

APP-RMS-VBR-002, Revision 0

Based on the review described above, the inspectors determined the licensee took adequate corrective actions to address the violation and the po tential impacts to the ITAAC have been appropriately addressed such that the acceptanc e criteria of ITAAC 3.5.00.01.i (823) can be met. NCV 05200025/2021005-04 is close d.
