U.S. Nuclear Regulatory Commission ND-20-0979 Enclosure Page 2 of 4 ITAAC Statement Design Commitment 10.c) The valves identified in Table 2.2.2-1 as having DAS control perform an active safety function after receiving a signal from the DAS.

Inspections/Tests/Analyses Testing will be performed on remotely operated valves listed in Table 2.2.2-1 using real or simulated signals into the DAS.

Acceptance Criteria The remotely operated valves identified in Table 2.2.2-1 as having DAS control perform the active function identified in the table after receiving a signal from the DAS.

ITAAC Determination Basis Testing was performed in accordance with Unit 3 preoperational test procedure and work order listed in Reference 1 to verify that the remotely operated valves identified in Combined License (COL) Appendix C Table 2.2.2-1 (Attachment A) as having Diverse Actuation System (DAS) control perform an active safety function after receiving a signal from DAS. Real signals were provided into the DAS and the valves in Attachment A were confirmed to perform the active function after receiving a signal from the DAS.

The preoperational testing confirms that each of the Passive Containment Cooling Water Storage Tank (PCCWST) isolation valves that have DAS control receive a signal from DAS and perform the required active function. Initially, the valves were verified to be in the non-actuated position (closed). The valves were remotely operated by manually initiating a containment cooling signal at the DAS panel in the Main Control Room (MCR) and verifying the valves perform their active function (transfer open). Each valve was verified to open using the Main Control Room (MCR) display as well as local inspection of each valve.

The Unit 3 preoperational test results in Reference 1 documented that the remotely operated valves listed in Attachment A as having DAS control perform the active function identified in Attachment A after receiving a signal from the DAS.

Reference 1 is available for NRC inspection as part of the ITAAC 2.2.02.10c 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 findings associated with this ITAAC. The review is documented in the ITAAC Completion Package (Reference 2) and is available for NRC review.

U.S. Nuclear Regulatory Commission ND-20-0979 Enclosure Page 3 of 4 IT AAC Completion Statement Based on the above information, SNC hereby notifies the NRG that ITAAC 2.2.02.10c was performed for VEGP Unit 3 and that the prescribed acceptance criteria were 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.
