U.S. Nuclear Regulatory Commission ND-22-0348 Enclosure Page 2 of 2 ITAAC Statement Design Commitment 13.c) The RCPs trip after receiving a signal from the DAS .

Inspections/Tests/Analyses Testing will be performed using real or simulated signals into the DAS .

Acceptance Criteria The RCPs trip after receiving a signal from the DAS .

ITAAC Determination Basis Testing was performed as described in ITAAC Technical Report SV3-RCS-ITR-800065 (Reference 1) to verify that the Reactor Coolant Pumps (RCPs) trip after receiving a signal from the Diverse Actuation System (DAS). Real signals were provided into the DAS and the RCPs were confirmed to trip after a signal is received from the DAS .

Each RCP Variable Frequency Drive (VFD) feeder breaker was placed in the closed position and a manual Core Makeup Tank (CMT) actuation was initiated. The CMT actuation signal from the DAS caused the RCPs to trip when the RCP VFD feeder breakers opened. The RCP VFD feeder breakers were verified locally to be open . The Unit 3 test results documented in Reference 1 confirm that each RCP trips after receiving a signal from the DAS .

Reference 1 is available for NRC inspection as part of the ITAAC 2.1.02.13c 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 2.1.02 .13c (Reference 2) and is ava ilable for NRC review.

ITAAC Completion Statement Based on the above information , SNC hereby notifies the NRC that ITAAC 2.1.02 .13c was performed for VEGP Unit 3 and that the prescribed acceptance criteria was 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.
