U.S. Nuclear Regulatory Commission ND-22-0793 Enclosure Page 2 of 3 ITAAC Statement Design Commitment:

1. The functional arrangement of the PXS is as described in the Design Description of this Section 2.2.3.

Inspections, Tests, Analyses:

Inspection of the as-built system will be performed.

Acceptance Criteria:

The as-built PXS conforms with the functional arrangement as described in the Design Description of this Section 2.2.3.

ITAAC Determination Basis An inspection of the as-built passive core cooling system (PXS) was conducted after completion of construction to confirm that the functional arrangement of the PXS is as described in the Design Description of Combined License (COL) Appendix C, Section 2.2.3. This inspection encompassed the structures, systems, and components (SSCs) identified in the COL Appendix C, Section 2.2.3, Design Description including those in Table 2.2.3-5 and Figure 2.2.3-1.

The inspection (walkdown) was completed in accordance with ND-RA-001-012, Functional and Physical Arrangement Scoping Process (Reference 1), which required the preparation of a detailed inspection plan. This inspection plan included the use of detailed drawings such as Piping and Instrumentation Drawings (P&IDs) or Single Line Elementary Drawings to perform visual observations and compare the as-built system to the Design Description.

The inspection results are documented in the Unit 4 Principal Closure Document (Reference 2) supporting the Unit 4 ITAAC 2.2.03.01 Completion Package (Reference 3) and verified that the SSCs are physically arranged and located to perform the functions described in the Design Description and referenced table and figure. The inspection results confirm that the as-built PXS conforms with the functional arrangement as described in the COL Appendix C, Section 2.2.3 Design Description.

The Unit 4 Principal Closure Document (Reference 2) is available for NRC inspection as well as the Unit 4 ITAAC 2.2.03.01 Completion Package.

ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all ITAAC findings pertaining to the subject ITAAC and associated corrective actions. This review found that there are no relevant ITAAC findings associated with this ITAAC. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.2.03.01 (Reference 3) and is available for NRC review.

U.S. Nuclear Regulatory Commission ND-22-0793 Enclosure Page 3 of 3 ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.2.03.01 was performed for VEGP Unit 4 and that the prescribed acceptance criteria were met.

Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed, ITAAC compliant condition in accordance with approved plant programs and procedures.
