U.S. Nuclear Regulatory Commission ND-18-0413 Enclosure 4 Page 2 of 3 ITAAC Statement Desion Commitment 7.d) Physical separation is maintainedbetween Class 1E divisions and between Class 1E divisions and non-Class 1E cables.
Insoections. Tests. Analvses Inspections ofthe as-built raceways that routeClass 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 racewaysthat route non-Class 1E cables is consistent with the following:
v) Non-Class 1E wiring that is not separated from Class 1Eor associated wiring bythe minimum separation distance or bya barrier or analyzed is considered as associated circuits and subject to Class 1E requirements.
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:
v.a) Forareas insidecontainment, non-Class 1Ewiring that is not separated from Class 1E or associated wiring bythe minimum separation distance or by a barrieror analyzed is treated as Class 1E wiring.
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, non-Class 1E wiring that is not separated from Class 1E or associated wiring by the minimum separation distance and forwhich no barrieror analysis is providedis considered as associated circuits and subject to Class 1E requirements. The subject ITAAC requires inspections of the Class 1E and non-Class 1E raceways insidecontainment to confirm that non-Class 1E wiring that is not separated from Class 1E or associated wiring by the minimum separation distance or by a barrier or analyzed is considered as associated circuitsand subject to Class 1E requirements. The Class 1E cables and raceways and non-Class1E cables inside containment are designed to be appropriatelyseparated in accordance with APP-GW-E1-001 (Reference 1). Installation Specifications provided to the constructoridentify 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 installation specifications are satisfied. Inspections are performed in accordance with the ConstructionQuality Verification Program 26139-000-4MP-T81C-N7101 (Reference 2). The completed inspection records document the
U.S. Nuclear Regulatory Commission ND-18-0413 Enclosure 4 Page 3 of 3 satisfactory 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.
Cable Separation Reports XXX (References 3 and 4) identify the inspection reports associated withthe 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:
For areas inside containment, non-Class 1E wiringthat is not separated from Class 1E or associated wiring by the minimumseparation distance or by a barrier or analyzed is considered as associated circuits and subject to Class 1E requirements.
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.v.a Completion Packages (References 5 and 6, respectively).
List of ITAAC Findings Inaccordance 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.
