Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 ITAAC Closure Notification on Completion of ITAAC 2.6.03.04a (Index Number 601 l

Ladies and Gentlemen:

In accordance with 1 O CFR 52.99(c)(1 ), the purpose of this letter is to notify the Nuclear Regulatory Commission (NRC) of the completion of Vogtle Electric Generating Plant (VEGP)

Unit 3 Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.6.03.04a (Index Number 601 ). This IT AAC verified that a simulated test signal exists at the Class 1 E equipment identified in COL Appendix C Table 2.6.3-1 when the assigned Class 1 E division is provided the test signal.

The closure process for this ITAAC is based on the guidance described in NEl-08-01, "Industry Guideline for the ITAAC Closure Process under 10 CFR Part 52" which is endorsed by the NRC in Regulatory Guide 1.215.

This letter contains no new NRC regulatory commitments. Southern Nuclear Operating Company (SNC) requests NRC staff confirmation of this determination and publication of the required notice in the Federal Register per 10 CFR 52.99.

If there are any questions, please contact Kelli Roberts at 706-848-6991.

Respectfully submitted,

ITAAC Statement

Design Commitment

4.a) The IDS provides electrical independence between the Class 1 E divisions.

Inspections, Tests, Analyses

Testing will be performed on the IDS by providing a simulated test signal in each Class 1 E division.

Acceptance Criteria

A simulated test signal exists at the Class 1 E equipment identified in Table 2.6.3-1 when the assigned Class 1 E division is provided the test signal.

ITAAC Determination Basis

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

SV3-I DS-ITR-800601 (Reference 1) documents completion of testing which ensures IDS provides electrical independence between Class 1 E divisions. Testing verified electrical independence of the divisions of Class 1 E 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 1 E 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 1 E equipment identified in Table 2. 6. 3-1 when the assigned Class 1 E 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.

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.
