U.S. Nuclear Regulatory Commission ND-22-0895 Enclosure Page 2 of 3 IT AAC Statement Design Commitment:

1. The functional arrangement of the CNS and associated systems is as described in the Design Description of this Section 2.2.1.

Inspections, Tests, Analyses:

Inspection of the as-built system will be performed.

Acceptance Criteria:

The as-built CNS conforms with the functional arrangement as described in the Design Description of this Section 2.2.1.

ITAAC Determination Basis An inspection of the as-built containment system (CNS) and associated systems was conducted after completion of construction to confirm that the functional arrangement of the CNS and associated systems is as described in the Design Description of Combined License (COL)

Appendix C, Section 2.2.1. This inspection encompassed the structures, systems, and components (SSCs) identified in the COL Appendix C, Section 2.2.1 Design Description, including those in Table 2.2.1-4 and Figure 2.2.1-1.

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 compared the as-built system to the Design Description.

The inspection results were documented in the Unit 4 Principal Closure Document (Reference 2) 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 confirmed that the as-built CNS and associated systems conform with the functional arrangement as described in the COL Appendix C, Section 2.2.1, Design Description.

The Principal Closure Document (Reference 2) is available for NRC inspection as well as the Unit 4 ITAAC 2.2.01.01 Completion Package (Reference 3).

IT AAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all lTAAC 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 2.2.01.01 (Reference 3) and is available for NRC review.

U.S. Nuclear Regulatory Commission ND-22-0895 Enclosure Page 3 of 3 ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.2.01.01 was performed for VEGP Unit 4 and that the prescribed acceptance criteria are 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.
