U.S. Nuclear Regulatory Commission ND-22-0142 Enclosure Page 2 of 4 ITAAC Statement Desian Commitment 6.a) The Class 1E components Identified in Table 2.2.5-1 are powered from their respective Class 1E division.

Inspections/Tests/Analvses Testing will be performed 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 2.2.5-1 when the assigned Class 1E division is provided the test signal.

ITAAC Determination Basis Testing was performed on the Class 1E components(equipment) identified in the VEGP Unit 3 COL Appendix C Table 2.2.5-1 (Attachment A)to demonstrate that they are powered from their respective Class IE division. This ITAAC performed testing on the Main Control Room Emergency Habitability System (VES)equipment identified in Table 2.2.5-1 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, are verified through the applicable portion of ITAAC 2.5.02.05a testing (Reference 1) and confirmed the PMS cabinets are powered from their respective Class IE division. SV3-VES-ITR-800263(Reference 2) documents completion of power verification activities from the PMS cabinets and the Class 1E power distribution panels to the equipment identified in Attachment A. Reference 2 first verified that power supply cables/wiring were installed and terminated from the applicable PMS cabinet and Class 1E power distribution panel 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 are powered from their respective Class 1E division.

The results of the testing are documented in SV3-VES-ITR-800263(Reference 2)and confirmed that a simulated test signal exists at the Class 1E equipment identified in Table 2.2.5-1 when the assigned Class 1E division provided the test signal.

References 1 and 2 are available for NRC inspection as part of the Unit 3 ITAAC 2.2.05.06a Completion Package (Reference 3).
