U.S. Nuclear Regulatory Commission ND-18-0413 Enclosure 2 Page 1 of 3 Southern Nuclear Operating Company ND-18-0413 Vogtle Electric Generating Plant (VEGP) Unit 3 and Unit 4 Docket No.: 52-025 & 52-026 Completion Plan for Uncompleted ITAAC 3.3.00.07d.iii.a [Index Number 803]
U.S. Nuclear Regulatory Commission ND-18-0413 Enclosure 2 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. Analvses Inspections ofthe as-built raceways that route Class 1E cables will be performedto confirm that the separation between raceways that route Class 1E cables of differentdivisions, 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 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.a) Where minimum separation distances are not met inside containment, the circuitsare run in enclosed raceways or barriers are provided.
ITAAC Completion Description 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 forcircuits that do notmeet the separation distance criteria of ITAAC 3.3.00.07d.ii.a may be provided by enclosed raceways or barriers. For circuits requiring enclosed raceways or barriers, the subject ITAAC requires inspections ofthe 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-Class1 E cables inside containment are designed to be appropriatelyseparated in accordance with APP-GW-E1-001 (Reference 1). Installation Specifications provided to the constructoridentify the separation criteria, consistent with the ITAAC commitment.
Class 1E electrical cables and raceways are installed in accordance with design drawings, installation specifications issued for construction and workpackage requirements. Completed raceway installation, in-progress cable installation, and completed cable terminations are inspected to ensure the separation installationspecifications are satisfied. Inspections are performed in accordance withthe Construction QualityVerification Program 26139-000-4MP-T81C-N7101 (Reference 2). The completed inspection records document the satisfactory 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.
U.S. Nuclear Regulatory Commission ND-18-0413 Enclosure 2 Page 3 of 3 Cable Separation Reports XXX (References 3 and 4) identify the inspection reports associated with the raceway separation inspections and 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:
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 3.3.00.07d.iv.a (Enclosure 3) or ITAAC 3.3.00.07d.v.a (Enclosure 4).
The Cable Separation Reports (References 3 and 4) are available for NRC inspection as part of the Unit 3 and Unit 4 ITAAC 3.3.00.07d.iii.a Completion Packages (References 5 and 6, respectively).
List of ITAAC Findings 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.
