U.S. Nuclear Regulatory Commission ND-22-0364 Enclosure Page 2 of 7 ITAAC Statement Design Commitment 4.a) The IDS provides electrical independence between the Class 1E divisions .

Inspections, Tests, Analyses Testing will be performed on the IDS 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 2.6.3-1 when the assigned Class 1E division is provided the test signal.

ITAAC Determination Basis Testing was performed on the Class 1E equipment identified in the VEGP Unit 3 COL Appendix C Table 2.6.3-1 (Attachment A) to demonstrate the Class 1Ede and Uninterruptible Power Supply System (IDS) provides electrical independence between Class 1E divisions. This ITAAC performed testing on the IDS equipment by providing a simulated test signal in each Class 1E division .

SV3-I DS-ITR-800601 (Reference 1) documents completion of testing which ensures IDS provides electrical independence between Class 1E divisions . Testing verified electrical independence of the divisions of Class 1E IDS by energizing a single division and verifying the presence or absence of power at all division components being tested , then the single division is de-energized. This same sequence was repeated until all division components identified in Table 2.6.3-1 as being Class 1E were verified to be energized/de-energized when the appropriate power source is cycled .

The Unit 3 component testing documented in Reference 1 confirms that a simulated test signal exists at the Class 1E equipment identified in Table 2.6.3-1 when the assigned Class 1E division is provided the test signal.

References 1 is available for NRC review, as well as the Unit 3 ITAAC 2.6.03.04a Completion Package (Reference 2).

ITAAC Finding Review In accordance with plant procedures for ITAAC completion , Southern Nuclear Operating Company (SNC) performed a review of all lTAAC findings and associated corrective actions.

This review found no relevant ITAAC findings associated with this ITAAC. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.6.03 .04a (Reference 2) and is available for NRC review.

U.S. Nuclear Regulatory Commission ND-22-0364 Enclosure Page 3 of 7 ITAAC Completion Statement Based on the above information , SNC hereby notifies the NRC that ITAAC 2.6.03.04a was performed for VEGP Unit 3 and that the prescribed acceptance criteria are met.

Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed , ITAAC compliant condition in accordance with approved plant programs and procedures.
