U.S. Nuclear Regulatory Commission ND-19-1529 Enclosure Page 2 of 3 ITAAC Statement Desian Commitment 8.b) The RMS provides for the transfer of control capability from the MCR to the RSW using multiple transfer switches. Each individual transfer switch Is associated with only a single safety-related group or with nonsafety-related control capability.

Inspections. Tests. Analvses i) An inspection will be performed to verify that a transfer switch exists for each safety-related division and the nonsafety-related control capability.

Acceptance Criteria i) A transfer switch exists for each safety-related division and the nonsafety-related control capability.

ITAAC Determination Basis Multiple ITAAC are performed to ensure that the Protection and Safety Monitoring System (PMS) provides for the transfer of control capability from the Main Control Room (MCR)to the Remote Shutdown Workstation (RSW) using multiple transfer switches. Each individual transfer switch is associated with only a single safety-related group or with nonsafety-related control capability. The subject ITAAC requires that an inspection be performed to verify that a transfer switch exists for each safety-related division and the nonsafety-related control capability.

The PMS and Plant Control System (PLS)transfer switches were installed in accordance with approved drawings and specifications released by engineering for construction. An inspection was performed to verify that a transfer switch exists for each safety-related division and the nonsafety-related control capability. The inspection was performed in accordance with SV3-OCS-ITR-800542(Reference 1), which requires performance of visual observations to compare the installed equipment to the approved drawings. The inspection results are also documented in SV3-OCS-ITR-800542 which serves as the Principal Closure Document supporting the ITAAC 2.5.02.08b.i Completion Package (Reference 2). The inspection report confirms that a transfer switch exists for each safety related division and the nonsafety-related control capability.

Principal Closure Document SV3-OCS-ITR-800542 is available for NRC inspection as part of the ITAAC 2.5.02.08b.i Completion Package.

ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company(SNC) performed a review of 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 2.5.02.08b.i (Reference 2) and available for NRC review.

U.S. Nuclear Regulatory Commission ND-19-1529 Enclosure Page 3 of 3 ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRG that ITAAC 2.5.02.08b.i was performed for VEGP Unit 3 and that the prescribed acceptance criteria are met.
