U.S. Nuclear Regulatory Commission ND-22-0088 Enclosure Page 2 of 4 ITAAC Statement Design Commitment 3.a) The Class 1E breaker control power for the equipment identified in Table 2.6.1-1 are powered from their respective Class 1E division.

Inspections/Tests/Analvses Testing will be performed on the ECS by providing a simulated test signal in each Class IE division.

Acceptance Criteria A simulated test signal exists at the Class 1E equipment identified in Table 2.6.1-1 when the assigned Class 1E division is provided the test signal ITAAC Determination Basis Testing was performed on the Class 1E breaker control power for the equipment identified in the VEGP Unit 3 COL Appendix C Table 2.6.1-1 (Attachment A)to demonstrate the breaker control power is powered from its respective Class 1E division. This ITAAC performs testing on the Main ac Power System (ECS)equipment identified in Table 2.6.1-1 by providing a simulated test signal in each Class IE division.

Class 1E power verification testing of the Protection and Safety Monitoring System (PMS) cabinets, associated with the equipment identified in Attachment A, is verified through the applicable portions of ITAAC 2.5.02.05a testing (Reference 1) and confirms the PMS cabinets are powered from their respective Class IE division. SV3-ECS-ITR 800582(Reference 2) documents completion of power verification activities from the PMS cabinets and the Class 1E power distribution panels for the breaker control power for 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 panels to the respective circuit breaker 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 breaker control power for the equipment identified in Appendix A is powered from its respective Class 1E division.

The results of the testing are documented in SV3-ECS-ITR 800582(Reference 2) and confirmed that a simulated test signal exists at the Class 1E equipment identified in Table 2.6.1-1 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 2.6.01.03a Completion Package (Reference 3).
