U.S. Nuclear Regulatory Commission ND-21-0286 Enclosure Page 2 of 3 ITAAC Statement Design Commitment 7.d) Physical separation is maintained between Class 1E divisions and between Class 1E divisions and non-Class 1E cables.

Inspections, Tests, Analyses Inspections of the as-built raceways that route Class 1E cables will be performed to confirm that the separation between raceways that route Class 1E cables of different divisions, and between raceways that route Class 1E cables and raceways that route non-Class 1E cables is consistent with the following:

iii) Where minimum separation distances are not maintained, the circuits are run in enclosed raceways or barriers are provided.

Acceptance Criteria Results of the inspection will confirm that the separation between raceways that route Class 1 E cables of different divisions, and between raceways that route Class 1E cables and raceways that route non-Class 1E cables is consistent with the following:

iii.a) Where minimum separation distances are not met inside containment, the circuits are run in enclosed raceways or barriers are provided.

ITAAC Determination Basis Multiple ITAAC are performed to ensure that physical separation is maintained between Class 1E divisions and between Class 1E divisions and non-Class 1E cables . In accordance with this ITAAC, physical separation for circuits that do not meet the separation distance criteria of ITAAC 3.3.00.0?d.ii.a may be provided by enclosed raceways or barriers. For circuits requiring enclosed raceways or barriers, the subject ITAAC requires inspections of the raceways that route Class 1E cables and raceways that route non-Class 1E cables inside containment to confirm that circuits are run in enclosed raceways or have barriers provided. The Class 1E cables and raceways and non-Class 1E cables inside containment are designed to be appropriately separated in accordance with APP-GW-E1-001 (Reference 1). Installation specifications provided to the constructor identify the separation criteria, consistent with the ITAAC commitment.

Class 1E electrical cables, raceways, and barriers were installed in accordance with design drawings, installation specifications issued for construction, and work package requirements.

Completed raceway installation , in-progress and completed cable installation, completed cable terminations , and barriers were inspected to ensure the separation installation specifications are satisfied. Inspections were performed in accordance with the Construction Quality Verification Program, 26139-000-4MP-T81C-N7101 (Reference 2), or the Quality Control Inspection Program, ND-EN-VNP-020 (Reference 5). The completed inspection records document the satisfactory separation between raceways that route Class 1E cables of different

U.S. Nuclear Regulatory Commission ND-21-0286 Enclosure Page 3 of 3 divisions, and between raceways that route Class 1E cables and raceways that route non-Class 1E cables.

Additional inspections were performed and documented following completion of Class 1E raceway in each room to confirm that separation requirements between raceways that route Class 1E cables of different divisions, and between raceways that route Class 1E cables and raceways that route non-Class 1E cables are met. Reference 3 identifies the inspections performed and confirms that the separation between raceways that route Class 1E cables of different divisions, and between raceways that route Class 1E cables and raceways that route non-Class 1E cables is consistent with the following:

Where minimum separation distances are not maintained inside containment, the circuits are run in enclosed raceways or barriers are provided.

Exceptions to the subject ITAAC are not included within the scope of this ITAAC and are addressed within the scope of ITAAC 3.3.00.0?d.iv.a or ITAAC 3.3.00.0?d.v.a.

Unit 3 Cable Separation Report (Reference 3) is available for NRC inspection as part of the Unit 3 ITAAC 3.3.00.0?d.iii.a Completion Package (Reference 4)

ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all ITAAC findings and associated corrective actions.

This review found no relevant ITAAC findings associated with this ITAAC and is documented in Reference 4.

ITAAC Completion Statement Based on the above information , SNC hereby notifies the NRC that ITAAC 3.3.00.0?d.iii.a was performed for VEGP Unit 3 and that the prescribed acceptance criteria are 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.
