U.S. Nuclear Regulatory Commission ND-22-0239 Enclosure Page 2 of 4 IT AAC Statement Design Commitment 7.b) The Class 1E components identified in Table 2.3.6-1 are powered from their respective Class 1E division.

Inspections/Tests/ Analyses Testing will be performed on the RNS by providing a simulated test signal in each Class 1E division.

Acceptance Criteria A simulated test signal exists at the Class 1E equipment identified in Table 2.3.6-1 when the assigned Class 1E division is provided the test signal.

IT AAC Determination Basis Testing was performed on the Class 1E components (equipment) identified in the VEGP Unit 3 COL Appendix C Table 2.3.6-1 (Attachment A) to demonstrate they are powered from their respective Class 1E division. This ITAAC performs testing on the Normal Residual Heat Removal System (RNS) equipment identified in Table 2.3.6-1 by providing a simulated test signal in each Class 1E division .

Class 1E power verification testing of the Protection and Safety Monitoring System (PMS) cabinets , associated with the equipment identified in Attachment A, was verified through applicable portions of ITAAC 2.5.02.05a component testing (Reference 1) and confirmed the PMS cabinets are powered from their respective Class 1E division. Unit 3 SV3-RNS-ITR-800368 (Reference 2) documents completion of power verification activities from the PMS cabinets and the Class 1E power distribution panels/motor control centers to the equipment identified in Attachment A. Reference 2 first verified that power supply cables/wiring are installed and terminated from the applicable PMS cabinet and Class 1E power distribution panel/motor control center to the respective component identified in Attachment A using approved construction drawings and cable/wiring termination documentation. Reference 2 then confirmed, via cable/wiring termination inspection documentation, that continuity testing was performed on each of the installed cables/wiring to confirm current flow within the installed cable/wiring. The combination of cable/wiring installation and termination verification, with the installed cable/wiring continuity testing, confirmed that the equipment identified in Appendix A is powered from its respective Class 1E division.

The Unit 3 technical reports (References 1 and 2) confirmed that a simulated test signal exists at the Class 1E equipment identified in Table 2.3.6-1 when the assigned Class 1E division is provided the test signal.

References 1 and 2 are available for NRC inspection as part of Unit 3 ITAAC Completion Packages (Reference 3).

ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all findings pertaining to the subject ITAAC and

U.S. Nuclear Regulatory Commission ND-22-0239 Enclosure Page 3 of 4 associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC .
