U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 and Unit 4 Resubmittai of Notice of Uncompleted ITAAC 225-davs Prior to initial Fuel Load item 2.6.03.041 [index Number 6091 Ladies and Gentlemen:

Pursuant to 10 CFR 52.99(c)(3), Southern Nuclear Operating Company hereby notifies the NRC that as of August 4, 2021, Vogtle Electric Generating Plant(VEGP) Unit 3 and Unit 4 Uncompleted Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.6.03.04i

[Index Number 609] has not been completed greater than 225-days prior to initial fuel load for Unit 4. The Enclosure describes the plan for completing this ITAAC. Southern Nuclear Operating Company will, at a later date, provide additional notifications for Unit 4 ITAAC that have not been completed 225-days prior to initial fuel load.

Southern Nuclear Operating Company previously submitted Notice of Uncompleted ITAAC 225-days Prior to Initial Fuel Load for Item 2.6.03.041 [Index Number 609] ND-19-0949

[ML19234A217], dated August 22, 2019. This resubmittai supersedes ND-19-0949 in its entirety and clarifies scope in Attachment A.

This notification is informed by the guidance described in 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. In accordance with NEI 08-01, this notification includes ITAAC for which required inspections, tests, or analyses have not been performed or have been only partially completed.

All ITAAC will be fully completed and all Section 52.99(c)(1) ITAAC Closure Notifications will be submitted to NRC to support the Commission finding that all acceptance criteria are met prior to plant operation, as required by 10 CFR 52.103(g).

This letter contains no new NRC regulatory commitments.

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

Respectfully submitted.

U.S. Nuclear Regulatory Commission ND-21-0614 Enclosure Page 2 of 6 ITAAC Statement Design Commitment 4.1) The IDS supplies an operating voltage at the terminals of the Class 1E motor operated valves identified in subsections 2.1.2, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.3.2, 2.3.6, and 2.7.1 that is greater than or equal to the minimum design voltage.

Inspections. Tests. Analvses Testing will be performed by measuring the voltage during motor starting at both the IDS battery and motor-operated valve motor terminals while each motor-operated valve is stroked. Analyses will be performed to verify that the voltage at the motor-operated valve motor terminals is greater than or equal to the minimum design voltage of each motor-operated valve with an IDS battery terminal voltage of 210 Vdc.

Acceptance Criteria A report exists and concludes that IDS can provide a voltage greater than or equal to each valve's minimum design voltage to the motor terminals of each motor-operated valve when power is supplied under design conditions from IDS batteries with battery terminal voltage at 210 Vdc while each motor-operated valve is stroked.

ITAAC Completlon Description Testing is performed by measuring the voltage during motor starting at both the Class 1E dc and uninterruptible power supply system (IDS) battery and motor-operated valve(MOV) motor terminals while each MOV is stroked. Analyses are performed to verify that the voltage at the MOV motor terminals is greater than or equal to the minimum design voltage of each MOV with an IDS battery terminal voltage of 210 Vdc.

Analyses are performed in accordance with SV3-IDS-E0C-004 and SV4-IDS-E0C-004 (References 1 and 2)to determine the voltage drop on each power circuit at a battery voltage of 210 Vdc and the resulting voltage at the MOV terminals during normal operating conditions, and accident conditions. References 1 and 2 are the basis of analyses performed in accordance with SV3-IDS-E0C-018 and SV4-IDS-E0C-018 (References 3 and 4). The analyses determine the expected voltage at the MOV terminals and define the method for the determination of the minimum acceptance voltage for each MOV during preoperational testing.

Each MOV identified in Combined License (COL) Appendix C subsections 2.1.2, 2.2.1,2.2.2, 2.2.3, 2.2.4, 2.3.2, 2.3.6, and 2.7.1 (Attachment A)is stroked individually in accordance with References 5 and 6. The voltage at the battery terminals and at the MOV terminals is recorded during MOV operation using installed maintenance and test equipment. The recorded voltage at the MOV terminals is analyzed in accordance with the method described in References 3 and 4, to compare proportional values when the tested battery voltage is higher or lower than the nominal voltage assumed in the analyses of References 3 and 4, to determine the minimum acceptance voltage for each MOV. A resulting proportional voltage that is greater than or equal to the minimum design voltage of each MOV confirms the tested voltage is bounded by the analyses in References 3 and 4.

The analyses and preoperational test results (References 1 through 6)confirm that IDS can provide a voltage greater than or equal to each MOV's minimum design voltage to the terminals

References 1 through 6 are available for NRG inspection as part of Unit 3 and Unit 4 ITAAC Completion Packages(Reference 7 and 8).

List of ITAAC Findings 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.
