52-025 U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 Jamie M. Coleman Regulatory Affairs Director Vogtle 3 & 4 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 7825 River Road Waynesboro, GA 30830 706-848-6926 tel ND-22-0276 10 CFR 52.99(c)(1)

ITAAC Closure Notification on Completion of ITAAC 2.2.05.09c (Index Number 8771 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) 2.2.05.09c (Index Number 8771. This ITAAC confirms that Main Control Room (MCR) Load Shed Panels identified in Combined License Appendix C Table 2.2.5-1 perform their active safety function after receiving a signal from the Protection and Safety Monitoring System (PMS). The closure process for this ITAAC is based on the guidance described in Nuclear Energy Institute (NEI) 08-01, "Industry Guideline for the ITAAC Closure Process under 10 CFR Part 52," which was 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.

U.S. Nuclear Regulatory Commission ND-22-0276 Enclosure Page 2 of 4 ITAAC Statement Design Commitment 9.c) The MCR Load Shed Panels identified in Table 2.2.5-1 perform their active safety function after receiving a signal from the PMS.

Inspections, Tests, Analyses Testing will be performed on the MCR Load Shed Panels listed in Table 2.2.5-1 using real or simulated signals into the PMS.

Acceptance Criteria The MCR Load Shed Panels identified in Table 2.2.5-1 perform their active safety function identified in the table after receiving a signal from the PMS.

ITAAC Determination Basis Testing was performed to demonstrate the Main Control Room (MCR) Load Shed Panels identified in Combined License (COL) Appendix C Table 2.2.5-1 (Attachment A) performed their active safety function after receiving a signal from the Protection and Safety Monitoring System (PMS).

Testing was performed in accordance with Unit 3 component test packages listed in Reference 1 and confirmed that the MCR Load Shed Panels identified in Attachment A performed their active safety function to de-energize MCR loads after receiving a signal from the PMS.

An actuation signal from PMS was generated using the PMS Maintenance and Test Panel (MTP) to actuate the MCR Load Shed Panel 1, Division A. The MCR Load Shed Panel was verified locally to have actuated after the receipt of the actuation signal and the stage 1 and stage 2 loads were verified to be de-energized. The MCR Load Shed Panel 1, Division A was reset and the loads were verified to be energized. This methodology was repeated for MCR Load Shed Panel 2, Division A, MCR Load Shed Panel 1, Division C, and MCR Load Shed Panel 2, Division C.

The completed Unit 3 component test results (reference 1) confirmed that the MCR Load Shed Panels identified in Table 2.2.5-1 perform their active safety function identified in the table after receiving a signal from the PMS.

Reference 1 is available for NRC inspection as part of Unit 3 ITAAC Completion Packages (Reference 2).

ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all findings pertaining to the subject ITAAC and associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.2.05.09c Completion Package (Reference 2) and is available for NRC review.

U.S. Nuclear Regulatory Commission ND-22-0276 Enclosure Page 3 of 4 ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.2.05.09c was performed for VEGP Unit 3 and that the associated acceptance criteria is met.
