For SRVs with serial numbers N900028-00-0009 and -0010, the inspectors reviewed S&W piping installation data sheets to verify quality control (QC) hold points for identification/marking, material traceability (including bolts, nuts, and gaskets), internal cleanliness, and calibration of torquing tools that were deemed satisfactory and signed-off by QC inspectors in accordance with the requirements of the ASME Code Section III, Article NCA-3000 with final signatures by the authorized nuclear inspector (ANI).
The inspectors reviewed S&W bolted joint data sheets to verify QC hold points for alignment/fit-up of the gaskets and flanges and the sequential torquing, in gradual steps, to the final values were deemed satisfactory and signed-off by QC inspectors in accordance with the requirements of the ASME Code Section III, Paragraph NB-2128, and Section II, Part D, Subpart 1, Table 4 with final signatures by the ANI.
- b. Findings No findings were identified.
1A02 (Unit 3) ITAAC Number 2.5.02.07a (534) / Family 10E (Unit 4) ITAAC Number 2.5.02.07a (534) / Family 10E
- a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number 2.5.02.07a (534). The inspectors used the following NRC IPs/sections to perform this inspection:
- 40600-02.04 - ITAAC Maintenance Controls
- 65001.E-02.03 - Qualification
- 65001.E-02.04 - Documentation
- 65001.E-02.06 - Problem Identification and Resolution On August 28, 2020, the licensee notified the NRC, via Event Number 54864, in accordance with 10 CFR 52.99(c)(2), that ITAAC 2.5.02.07a (534) and ITAAC 2.5.02.07e (538) for both units required additional actions to restore their completed status.
On August 26, 2020, the licensee determined a design change, issued for several protection and safety monitoring system (PMS) isolation barrier assemblies (ISBs),
materially altered the basis for determining the ITAAC 534 and ITAAC 538 acceptance criteria were met. The modified ISBs will require testing per Institute of Electrical and Electronic Engineers (IEEE) 384-1981, IEEE Standard Criteria for Independence of Class 1E Equipment and Circuits.
4
The inspectors performed an inspection associated with implementation of field change notice (FCN) SV3-GW-GCW-654. The FCN was required to maintain the completed status of ITAAC 2.5.02.07a following the submittal of Unit 3 ITAAC closure notification ND-17-0572 (ADAMS accession number ML17093A286), which was originally submitted on March 31, 2017. The FCN was associated with the PMS and plant control system (PLS) 1E/non-1E isolation devices that prevent credible faults from propagating into the Class 1E PMS. During supplemental vendor testing of the isolation barriers a fault path was identified and limited to the non-1E side of the barrier. The FCN was issued to implement a hardware modification to address the fault path.
The inspectors reviewed the licensee's condition report (CR) 50054381 and corrective action record (CAR) 80002990, which documented the licensee review and resolution of engineering & design coordination report (E&DCR) APP-GW-GEF-2540. The E&DCR proposed an addition of a fuse harness to limit fault current on the Non-1E side of the isolation barriers. The inspectors reviewed the associated work order SV3-PMS-T0W-1222073 to verify test steps were established to furnish identifiable and retrievable evidence of post maintenance testing of the FCN.
The inspectors reviewed the E&DCR to verify the design changes made to the PMS/PLS isolation barrier were performed in accordance with 10 CFR Part 50 Appendix B, Criterion III, Design Control. Specifically, the inspectors performed the review to verify the design change was subject to control measures commensurate with those applied to the original design and were approved by the original design organization. The inspectors reviewed the E&DCR to verify a justification was provided for the design change and the revised design was correctly translated into the updated design output documents. The inspectors reviewed factory acceptance test (FAT) APP-PMS-VPR-021 to verify the test results documented compliance with IEEE 384-1981, demonstrating the safety system was not degraded below an acceptable level as a result of maximum credible fault voltages. The inspectors reviewed all test anomalies to verify they had been described and dispositioned.
The inspectors reviewed APP-PMS-VBR-003 to verify addition of the hardware modification to the isolation barrier assembly was qualified for use in the PMS cabinets. Specifically, the inspectors verified the qualification evaluation was performed and documented and the results concluded no impacts on the environmental and seismic qualification.
The inspectors reviewed the licensee's ITAAC closure notification, ITAAC maintenance screening, and ITAAC maintenance impact technical evaluation (TE) 60014755 to verify ITAAC maintenance controls were implemented in accordance with ND-RA-001-009 and the ITAAC notification process conformed to the regulatory requirements of 10 CFR 52.99(c).

In other instances, the bolts were over-torqued forcing the head to seat, then loosened and torqued to the correct design value.
- b. Findings Introduction The inspectors identified an unresolved item (URI) associated with nonconformances identified in the installation of the cable tray system in the Unit 3 auxiliary building. This URI is being opened to determine if the performance deficiency is of more-than-minor significance.

Description The inspectors reviewed E&DCRs APP-SH25-GEF-850014 and APP-SH25-GEF-850017. Based on this review, the inspectors determined the design of the cable tray splice connections assumed the bolts clamped the splice plates firmly to the cable tray side rail. The inspectors reviewed the AP1000 Electrical Installation Specification. This specification stated that cable tray installation shall be per the engineering drawings, APP-ECS-E9-Series. The inspectors reviewed the typical connection details depicted on drawing SV3-ECS-E9-012-R8. Typical details of Seismic Category I Cable Tray Splice Plates for HDGAF Metal (B-Line) Cable Trays were provided in details T21, T22, T22A, and T22B on SV3-ECS-E9-012-R8. These details required the nuts of the bolts used in the connections to be tightened to 19 ft-lbs and did not specify a permissible gap between the bolt head and the cable tray side rail or the plies of the connection.
Additionally, these details did not provide leeway to tighten the bolts more than the specified value. Standard practices for the installation of structural bolted connections are to tighten the bolts to bring the faying surfaces into contact with one another prior to applying any required pre-tensioning. Failure to follow these practices may result in some bolts in the connection not achieving the required torque.
The inspectors determined the licensees failure to install the splice plate connections in accordance with the engineering drawing was a performance deficiency.
10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings states, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Design Specification, APP-G1-V8-001, AP1000 Electrical Installation Specification, Revision 8, Section 3.4.2 states, in part, that cable tray installation shall be per the engineering drawings, APP-ECS-E9-Series. Contrary to the above, connections between cable tray sections were not accomplished per the engineering drawing as evidenced by the following:
- 1. Not all the bolts used in the connections of cable trays SV3-1242-ER-AZT04B, SV3-1212-ER-AYT01D, and SV3-1212-ER-AYT01F were fully seated and in firm contact with the cable tray as required by details T21, T22, T22A, and T22B on design drawing SV3-ECS-E9-012-R8.
- 2. In some instances, additional tension above the required 19 ft-lbs specified in details T21, T22, T22A, and T22B on design drawing SV3-ECS-E9-012-R8 was used to get bolt heads fully seated.
The inspectors determined this performance deficiency was not material to the acceptance criteria of an ITAAC. However, an URI has been opened pending completion and review of the licensees extent of condition survey and a bounding engineering evaluation. The inspectors will use this information to assist in determining whether the performance deficiency is of more-than-minor significance. The licensee entered this issue into its CAP for evaluation and determination of appropriate corrective actions (CR 50078244).

- a. Inspection Scope The inspectors performed an inspection of nonconformances identified in the installation of the cable tray system in the Unit 3 auxiliary building. Specifically, some connections between cable tray systems carrying safety-related cables and structural supports were not installed in accordance with engineering drawings. In some instances, clips specified for horizontal sections of cable trays were used to brace vertical cable tray sections without approval of the design authority. In other instances, nuts used in bolted connections did not have full thread engagement and the clips were deformed plastically during installation. Examples of these conditions were found at the following locations: SV3-1232-SH-E1403, SV3-1232-SH-E1404, and SV3-1232-ER-C2TOZA.
- b. Findings Introduction The inspectors identified an URI associated with nonconformances identified in the installation of the cable tray system in the Unit 3 auxiliary building. This URI is being opened to determine if the performance deficiency is of more-than-minor significance.
Description The inspectors reviewed the AP1000 Electrical Installation Specification. This specification stated that cable tray installation shall be per the engineering drawings, APP-ECS-E9-Series. The inspectors reviewed the typical connection notes and details depicted on drawings SV3-ECS-E9-062-R2 and SV3-ECS-E9-064-R0 and pictures of the connections at the locations where the nonconformances were identified. Based on this review, the inspectors determined a cable tray hold down clamp specified for horizontal cable trays was used for vertical cable tray section SV3-1232-ER-CZT02A at support SV3-1232-SH-E1403. The inspectors also determined two nuts used in a bolted angle connection between cable tray section SV3-1232-SH-E1404 and a support lacked proper thread engagement as defined in Note 2.8(B) on drawing SV3-ECS-E9-062-R2 and the angle was deformed plastically during installation. Note 2.8(B) on SV3-ECS-E9-062-R2 states, in part, that bolts are acceptable as long as the bolt length selected achieves a minimum of one full thread above the associated nut. A typical detail of a cable tray expansion guide for horizontal Seismic Category I HDGAF steel solid through cable trays is provided in detail T04A on SV3-ECS-E9-064-R0.

- 2. Detail T04A on SV3-ECS-E9-064-R0 is not specified for vertical cable trays.
However, it was used for vertical cable tray section SV3-1232-ER-CZT02A at support SV3-1232-SH-E1403.
The inspectors determined this performance deficiency was not material to the acceptance criteria of an ITAAC. However, an URI has been opened pending completion and review of the licensees extent of condition survey and a bounding engineering evaluation.

- a. Inspection Scope The inspectors performed an inspection of the installation of junction boxes in the Unit 3 electrical raceway system. Specifically, the inspectors reviewed quality records, including the design specification, work packages, inspection records, nonconformance reports, engineering service requests, CRs, procedures, vendor manuals, and drawings to verify:
- the design was implemented in accordance with regulatory requirements, including applicable sections of the Updated Final Safety Analysis Report and the IEEE standards;
- differences between the as-built configuration and the design were reconciled in the design report;
- the design drawings were revised to reflect the as-built configuration by qualified personnel;
- issues identified during the inspection were entered into the CAP in accordance with the CAP requirements;
- design changes were evaluated and implemented in accordance with established site procedures; and
- design deviations or nonconforming conditions were identified, documented, and dispositioned in accordance with site procedures.
- b. Findings Introduction The inspectors identified an URI associated with non-conformances identified with the installation of junction boxes in the Unit 3 electrical raceway system. Specifically, it was identified that two out of four spring nuts from junction box SV3-1232-ER-CZP08, and later observed on junction box SV3-1232-ER-CZP04, were not properly seating within the Unistrut channel supports. This URI is being opened to determine if the performance deficiency is material to the acceptance criteria of an ITAAC.
Description The inspectors identified that two out of four bolting connections for junction box SV3-1232-ER-CZP08 had misaligned spring nuts and the licensee initiated CR 50075790 to address this condition. CR 50075381 was also initiated on January 21, 2021 for a misaligned spring nut identified within the connections of junction box SV3-1232-ER-CZP04. Specifically, the inspectors identified that steps 3290 and 3300 of work package SV3-1232-ERW-1021720 required installation per SV3-G1-V8-001 and SV3-ECS-E9-Series to satisfy design requirements. SV3-ECS-E9-030, Note 3.3, stated, in part, that bolts shall be installed and torqued pursuant to the manufacturers requirements for the type of fitting and bolt size. Manufacturers requirements specified the serrated teeth of the nut are designed to lock into the in-turned edges of the Unistrut channels, to complete a strong, vise-like connection. These spring nuts were not properly seating or aligned in the Unistrut supports and were already QC inspected and accepted during the installation of these junction boxes.
16
The inspectors determined the licensees failure to install safety-related junction boxes in accordance with design specifications APP-G1-E1-003, SV3-G1-V8-001, vendor requirements and work order instruction SV3-1232-ERW-1021720 is a performance deficiency. ESR 50076220 was also initiated to evaluate the as-built condition.
Westinghouse evaluation SVP-SV0-006208, Evaluation of Junction Box SV3-1232-ER-CZP08 for ESR 50076220, determined the two misaligned spring nuts did not impact the junction boxs ability to perform its safety-related function. However, Unistrut spring nuts are commonly used as component supports, therefore CR 50077190 was initiated to determine the effect, causes, and extent-of-condition of misaligned spring nuts on other safety-related components and/or ITAAC-related SSCs.
On March 8, 2021, the inspectors determined the conditions adverse to quality identified in CRs 50004237 and 50075381, which dealt with spring nuts not properly seating on Unistrut supports for junction boxes, was a performance deficiency. An URI was opened to determine whether the performance deficiency is material to the acceptance criteria of an ITAAC. In response, the licensee opened CR 50083759 to address this concern.
