U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 ITAAC Closure Notification on Completion of ITAAC 2.3.09.02b rindex Number 4221 Ladies and Gentlemen:

In accordance with 10 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 2.3.09.02b [Index Number 422]. This ITAAC verified that testing was performed on Containment Hydrogen Control System components, each non-Class 1E power group is powered from their respective non-Class IE power group, and simulated test signal exists at the containment hydrogen control component when the assigned non-Class 1E power group is provided the test signal.

The closure process for this ITAAC is based on the guidance described in NEI-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.

U.S. Nuclear Regulatory Commission ND-22-0080 Enclosure Page 2 of 7 ITAAC Statement Deslon Commitment 2.b) The components identified in Table 2.3.9-2 are powered from the respective non-Class 1E power group.

Inspections. Tests. Analyses Testing will be performed by providing a simulated test signal in each non-Class 1E power group.

Acceptance Criteria A simulated test signal exists at the equipment identified in Table 2.3.9-2 when the assigned non-Class 1E power group is provided the test signal.

ITAAC Determination Basis Testing is performed on the components(equipment) identified in the VEGP Unit 3 COL Appendix C Table 2.3.9-2(Attachment A)to demonstrate they are powered from their respective non-Class 1E power group. This ITAAC performs testing on the equipment identified in Attachment A by providing a simulated test signal in each non-Class 1E power group.

The Unit 3 component test work order identified in Reference 1 documents completion of power verification activities from the non-Class 1E power supplies to the components in Attachment A.

This testing verified that power supply cables/wiring are installed and terminated from the applicable non-Class 1E power supply to the respective containment hydrogen control components in Attachment A. The component testing performed in Reference 1 confirms that the containment hydrogen control components are powered from their respective non-Class 1 E power supply.

The Unit 3 component testing documented in Reference 1 confirm that a simulated test signal exists at the equipment identified in Table 2.3.9-2 when the assigned non-Class 1E power group is provided the test signal.

Reference 1 is available for NRC inspection, as well as the Unit 3 ITAAC 2.3.09.02b 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 ITAAC findings and associated corrective actions.

This review found no relevant ITAAC findings associated with this ITAAC.

ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.3.09.02b was performed for VEGP Unit 3 and that the prescribed acceptance criteria are met.

U.S. Nuclear Regulatory Commission ND-22-0080 Enclosure Page 3 of 7 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.
