U.S. Nuclear Regulatory Commission ND-22-0165 Enclosure Page 2 of 4 ITAAC Statement Design Commitment 9.b) The Class 1E components identified in Table 2.1.3-1 are powered from their respective Class 1 E division.

Inspections/Tests/ Analyses Testing will be performed by providing simulated test signals in each Class 1E division.

Acceptance Criteria A simulated test signal exists for Class 1 E equipment identified in Table 2.1.3-1 when the assigned Class 1E division is provided the test signal.

ITAAC Determination Basis Testing was performed on the Class 1 E components (equipment) identified in the VEGP Unit 3 COL Appendix C Table 2.1.3-1 (Attachment A) to demonstrate they are powered from their respective Class 1 E division. This ITAAC performed testing on equipment identified in Table 2.1.3-1 by providing a simulated test signal in each Class 1E division.

Class 1 E power verification testing of the Protection and Safety Monitoring System (PMS) cabinets that provide power to the equipment identified in Attachment A, was verified through the applicable portions of ITAAC 2.5.02.0Sa component testing (Reference 1) and confirmed the PMS cabinets are powered from their respective Class 1 E division. SV3-RXS-ITR-800083 (Reference 2) documents completion of power verification activities from the PMS cabinets 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 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 1 E division.

SV3-RXS-ITR-800083 (Reference 2) confirmed that a simulated test signal exists at the Class 1 E equipment identified in Table 2.1.3-1 when the assigned Class 1 E division is provided the test signal.

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