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 2.2.03.11 c.ii (Index Number 2131 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 2.2.03.11c.ii (Index Number 2131. This ITAAC confirms that the remotely operated valves other than squib valves , identified in Combined License (COL) Appendix C Table 2.2.3-1 as having Diverse Actuation System (DAS) control , perform the active function identified in Table 2.2.3-1 after receiving a signal from DAS. 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.

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

U.S. Nuclear Regulatory Commission ND-22-0311 Enclosure Page 2 of 4 IT AAC Statement Design Commitment 11 .c) The valves identified in Table 2.2.3-1 as having DAS control perform their active function after receiving a signal from the DAS.

Inspections/Tests/Analyses ii) Testing will be performed on the remotely operated valves other than squib valves identified in Table 2.2.3-1 using real or simulated signals into the DAS.

Acceptance Criteria ii) Remotely operated valves other than squib valves perform the active function identified in Table 2.2.3-1 after a signal is input to the DAS.

ITAAC Determination Basis Multiple ITAAC are performed to verify that the valves identified in Combined License (COL)

Appendix C Table 2.2.3-1 (Attachment A) as having Diverse Actuation System (DAS) control perform an active function after receiving a signal from DAS. The subject ITAAC performed testing on the remotely operated valves, other than squib valves, listed in Attachment A.

Testing was performed as described in ITAAC Technical Report SV3-PXS-ITR-800213 (Reference 1) to verify that the remotely operated valves identified in Attachment A as having DAS control perform an active function after receiving a signal from DAS. Testing was performed on the remotely operated valves using real signals into the DAS to verify they performed the active function identified in Attachment A after a signal was input to the DAS. The valves listed in Attachment A were placed into their initial position , the Main Control Room (MCR) DAS Panel manual actuations were enabled, and the appropriate DAS Manual Actuation Switch was actuated. Each valve was verified to transfer to the active position in the MCR and locally.

Reference 1 confirmed that each remotely operated valve that is DAS controlled, other than squib valves, performed the active function listed in Attachment A after a signal is input to the DAS.

Reference 1 is available for NRC inspection as part of the ITAAC 2.2.03.11 c.ii 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 findings pertaining to the subject ITAAC and associated corrective actions. This review found there were no relevant ITAAC findings associated with this ITAAC. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.2.03.11 c.ii (Reference 2) and is available for NRC review.

ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.2.03.11 c.ii was performed for VEGP Unit 3 and that the prescribed acceptance criteria was met.
