U.S. Nuclear Regulatory Commission ND-22-0162 Enclosure Page 2 of 5 ITAAC Statement Design Commitment 6.b) The Class 1E components identified in Table 2.2.1-1 are powered from their respective Class 1E division .

Inspections/Tests/Analyses Testing will be performed by providing a simulated test signal in each Class 1E division.

Acceptance Criteria A simulated test signal exists at the Class 1E equipment identified in Table 2.2.1-1 when the assigned Class 1E division is provided the test signal.

ITAAC Determination Basis Testing was performed on the Class 1E components (equipment) identified in the VEGP Unit 3 COL Appendix C Table 2.2.1-1 (Attachment A) to demonstrate they are powered from their respective Class 1E division . This ITAAC performed testing on the Containment System (CNS) equipment identified in Table 2.2.1-1 by providing a simulated test signal in each Class 1E division . The Class 1E electrical penetrations identified in Attachment A are also tested by this ITAAC.

The electrical penetrations identified in Attachment A provide electrical continuity from Class 1E power supplies Outside Reactor Containment (ORC) to Class 1E equipment Inside Reactor Containment (IRC) and are not themselves powered components . Multiple Class 1E component and equipment ITAAC perform Class 1E power verifications that include power verifications through the electrical penetrations identified in Attachment A.

For the remaining equipment identified in Attachment A , SV3-CNS-ITR-800103 (Reference 1) documents completion of power verification activities from the Protection and Safety Monitoring System (PMS) cabinets and the Class 1E power distribution panels/motor control centers to the equipment identified in Attachment A. Class 1E power verification testing of the PMS cabinets ,

associated with the equipment identified in Attachment A, was verified through applicable portions of ITAAC 2.5.02.05a testing (Reference 2) and confirmed the PMS cabinets are powered from their respective Class 1E division. Reference 1 fi rst verified that power supply cables/wiring are installed and terminated from the applicable PMS cabinet and Class 1E power distribution panel/motor control center to the respective component identified in Attachment A using approved construction drawings and cable/wiring termination documentation . Reference 2 then confirmed , via cable/wiring termination inspection documentation , that continuity testing was performed on each of the installed cables/wiring to confirm current flow within the installed cable/wiring . The combination of cable/wiring installation and termination verification , with the installed cable/wiring continuity testing , confirmed that the equipment identified in Appendix A is powered from its respective Class 1E division.

The Unit 3 technical reports (References 1 and 2) confirm that a simulated test signal exists at the Class 1E equipment identified in Table 2.2 .1-1 when the assigned Class 1E division is provided a test signal.

U.S. Nuclear Regulatory Commission ND-22-0162 Enclosure Page 3 of 5 References 1 and 2 are available for NRC inspection as part of Unit 3 ITAAC 2.2.01 .06b Completion Package (Reference 3) .

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 are no relevant ITAAC findings associated with this ITAAC .

The ITAAC completion review is documented in the Vogtle Unit 3 ITAAC Completion Package for ITAAC 2.2.01 .06b (Reference 3) and is available for NRC inspection .

ITAAC Completion Statement Based on the above information , SNC hereby notifies the NRC that ITAAC 2.2.01 .06b 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 .
