U.S. Nuclear Regulatory Commission ND-22-0139 Enclosure Page 2 of 4 ITAAC Statement Design Commitment:

5.b) The boundaries between rooms identified in Table 3.3-2 of the auxiliary building are designed to prevent flooding of rooms that contain safety-related equipment.

Inspections, Tests, Analyses:

An inspection of the auxiliary building rooms will be performed.

Acceptance Criteria:

A report exists that confirms floors and walls as identified on Table 3.3-2 have provisions to prevent flooding between rooms up to the maximum flood levels for each room defined in Table 3.3-2.

ITAAC Determination Basis An inspection of the boundaries between the rooms identified in Vogtle Electric Generating Plant (VEGP) Unit 3 Combined License (COL) Appendix C Table 3.3-2 (Attachment A), was performed to demonstrate that the boundaries between these rooms were designed and constructed to prevent flooding of rooms that contain safety-related equipment.

Inspections were performed of auxiliary building rooms to demonstrate that floors and walls as identified in Table 3.3-2 have provisions to prevent flooding between rooms up to the maximum flood levels for each room defined in COL Appendix C Table 3.3-2 (Attachment A). An inspection plan was prepared to identify all openings and penetrations on the floors and walls up to the maximum flood levels of the rooms. Each as-built opening or penetration observed and measured to be below the corresponding maximum flood level was inspected to ensure that the openings and penetrations were sealed as specified in the design documents. A final walkdown of the floors and walls was performed to ensure that all openings and penetrations were identified and inspected.

The inspection plan and results of the visual inspection of the floors and walls are documented in the Unit 3 Principal Closure Document (PCD) (Reference 1), and confirms floors and walls as identified on COL Appendix C Table 3.3-2 have provisions to prevent flooding between rooms up to the maximum flood levels for each room defined in COL Appendix C Table 3.3-2 (Attachment A).

Reference 1 is available for NRC inspection as part of the Unit 3 ITAAC 3.3.00.0Sb Completion Package (Reference 2).

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 3.3.00.0Sb (Reference 2) and is available for NRC review.

U.S. Nuclear Regulatory Commission ND-22-0139 Enclosure Page 3 of 4 ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 3.3.00.05b was performed for VEGP Unit 3 and that the prescribed acceptance criteria were met.
