U.S. Nuclear Regulatory Commission ND-22-0149 Enclosure Page 2 of 4 ITAAC Statement Design Commitment 6.a) The Class 1E components identified in Table 2.7.1-1 are powered from their respective Class IE division.

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

Acceptance Criteria A simulated test signal exists at the Class IE equipment identified in Table 2.7.1-1 when the assigned Class 1E division is provided the test signal.

ITAAC Determination Basis Testing was performed on the Class IE components(equipment) identified in the VEGP Unit 3 COL Appendix C Table 2.7.1-1 (Attachment A)to demonstrate that they are powered from their respective Class 1E division. This ITAAC performed testing on the Nuclear Island Nonradioactive Ventilation System (VBS)and Sanitary Drainage System (SDS) equipment identified in Table 2.7.1-1 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, was verified through the applicable portion of ITAAC 2.5.02.05a testing (Reference 1) and confirms the PMS cabinets are powered from their respective Class IE division. SV3-VBS-ITR 800687(Reference 2) documents completion of power verification activities from the PMS cabinets and the Class 1E motor control centers 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 motor control center to the respective equipment 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-VBS-ITR 800687(Reference 2)and confirmed that a simulated test signal exists at the Class 1E components identified in Table 2.7.1-1 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 2.7.01.06a Completion Package (Reference 3).
