Description of Change:
The SLRA is revised to confirm SLR scoping was performed on electrical and I&C systems at PSL against the criteria in 10 CFR 54.4(a)(1), (a)(2) and (a)(3). The SLRA is revised to add Cable Bus to Section 2.5.1.2. The SLRA is revised to add specific language from SLR-ISG-2021-04-ELECTRICAL to the inaccessible medium-voltage, instrument & control, and low-voltage power cable AMPs in Appendices A1 and A2, as requested by NRC. This change aligns the Appendix A1 and Appendix A2 AMP descriptions with SLRA Section 2.1.6.1 and the specific language updates shown in the ISG. Appendix B, Section B.2.3.38 is also revised to be consistent with the SLR-ISG-2021-04-ELECTRICAL terminology.
Section B.2.3.40 is revised for consistent wording for the XI.E3 series AMPs.
SLRA Section 2.1.3.3, third paragraph, page 2.1-6, is revised as follows:
The first item includes NNS SSCs credited as mitigative design features or for providing system functions relied on by SR SSCs in the PSL Units 1 and 2 CLBs. These NNS SSCs are identified by reviewing the PSL Unit 1 and 2 UFSARs and other CLB documents. In addition, a supporting system review was performed to identify any NNS mechanical systems or electrical and I&C systems that supports a SR intended function of a system included within the scope of SLR in accordance with 10 CFR 54.4(a)(1). Any NNS mechanical or electrical and I&C systems identified during this review are included within the scope of SLR in accordance with 10 CFR 54.4(a)(2).
SLRA Section 2.1.4.2.1, second paragraph, page 2.1-13, is revised as follows:
The identification of the PSL SSCs determined to be within the scope of 10 CFR 54.4(a)(2) for original PSL license renewal is described in the original Unit 1 and Unit 2 scoping reports.
These reports were used as a starting point for the determination of the mechanical, electrical and I&C, and civil/structural SSCs within the scope of 10 CFR 54.4(a)(2) for PSL SLR. Additional sources of information used to determine this scope includes the original license renewal NRC Safety Evaluation Report, NUREG-1779, plant design modifications implemented between January 1, 2003 and October 1, 2020, and the information sources listed in Section 2.1.2.
SLRA Section 2.1.4.5, last paragraph, page 2.1-19, is revised as follows:
Electrical and I&C systems at PSL have been scoped for SLR with the criteria of 10 CFR 54.4(a)(1), (a)(2), and (a)(3). Electrical and I&C components of in-scope electrical and in-scope mechanical systems are placed in commodity groups and are screened as commodities. The determination of SLR system and structure boundaries are further described in the screening procedures for mechanical systems (Section 2.1.5.1), civil structures (Section 2.1.5.2), and electrical and I&C systems (Section 2.1.5.3).

2.5.1.2 Application of Screening Criterion 10 CFR 54.21(a)(1)(i) to the Electrical and I&C Components and Commodities Following the identification of the electrical and I&C components and commodity groups, the criterion of 10 CFR 54.21(a)(1)(i) is applied to identify electrical and I&C commodity groups that perform their functions without moving parts or without a change in configuration or properties. The following electrical and I&C commodity groups meet the screening criteria of 10 CFR 54.21(a)(1)(i) for PSL:
- Electrical Penetration Assemblies
- Insulated cables and connections
- Uninsulated ground conductors SLRA Appendix A1, Section 19.2.2.38, pages A1-37 and A1-38 (1st paragraph of section), is revised as follows:
The PSL Electrical Insulation for Inaccessible Medium-Voltage Power Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements AMP is a new AMP. The purpose of this AMP is to provide reasonable assurance that the intended functions of inaccessible medium-voltage power cables (operating voltages of 2 kV to 35 kV) that are not subject to the EQ requirements of 10 CFR 50.49 are maintained consistent with the CLB through the SPEO. This AMP applies to all inaccessible (e.g., installed in buried conduit, embedded raceway, cable trenches, cable troughs, duct banks, vaults, manholes, or direct-buried installations) non-EQ medium-voltage power cables that are within the scope of subsequent license renewal (SLR) and potentially exposed to wetting or submergence (i.e., significant moisture). Significant moisture is defined as exposure to moisture that lasts more than three days (i.e., long-term wetting or submergence over a continuous period), which if left unmanaged, could potentially lead to a loss of intended function. Cable wetting or submergence that results from event-driven occurrences and is mitigated by is minimized due to effective automatic or passive drainsage is not considered significant moisture for the purposes of this AMP.

This AMP applies to underground (e.g., installed in buried conduit, embedded raceway, cable trenches, cable troughs, duct banks, vaults, manholes, or direct buried installations) low-voltage power cables, including those designed for continuous wetting or submergence, within the scope of subsequent license renewal (SLR) that are potentially exposed to significant moisture.

Significant moisture is defined as exposure to moisture that lasts more than three (3) days (i.e., long-term wetting or submergence over a continuous period) that if left unmanaged, could potentially lead to a loss of intended function. Cable wetting or submergence that occurs for a limited time, as in the case of automatic or passive drainsage, is not considered significant moisture for this AMP.
SLRA Section B.2.3.38 (5th paragraph of section), page B-271 is revised as follows:
Inaccessible non-EQ medium-voltage power cables within the scope of SLR exposed to significant moisture will be tested to determine the age-related degradation of their electrical insulation.
