U.S. Nuclear Regulatory Commission ND-18-0511 Enclosure 4 Page 1 of 3 Southern Nuclear Operating Company ND-18-0511 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.v.c [Index Number 811]
U.S. Nuclear Regulatory Commission ND-18-0511 Enclosure 4 Page 2 of 3 ITAAC Statement Desion Commitment 7.d) Physical separation is maintained between Class 1Edivisions and between Class 1E divisions and non-Class 1E cables.
Inspections. Tests. Analvses Inspections of theas-built raceways that route Class1Ecableswill be performed toconfirm that the separation between raceways that route Class 1Ecablesofdifferent divisions, and between raceways that route Class 1Ecablesand raceways that route non-Class 1Ecables isconsistent with the following:
v) Non-Class 1Ewiring that is not separatedfrom Class 1Eorassociated wiring bythe minimum separation distance or by a barrier oranalyzed is considered as associated circuits andsubject to Class 1E requirements.
Acceptance Criteria Results ofthe inspection will confirm thatthe 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.c) For areas inside the radiologically controlled area ofthe auxiliary building, non-Class 1E wiring thatis not separated from Class1Eorassociated wiring bythe minimum separation distance or by a barrieror analyzed is treated as Class 1E wiring.
ITAAC Completion Description Multiple ITAAC are performed to ensurethatphysical separation is maintained between Class 1E divisions and between Class 1E divisions and non-Class 1E cables. In accordance with this ITAAC, non-Class1E wiring that is notseparated from Class 1Eor associated wiring bythe minimum separation distanceandforwhich no barrier or analysis is provided is considered as associated circuits and subject to Class 1E requirements. The subject ITAAC requires inspections of theClass1Eand non-Class 1Eraceways inside the radiologically controlled area of the auxiliary building to confirm thatnon-Class 1Ewiring that is not separated from Class1E or associated wiring bythe minimum separation distanceor bya barrier oranalyzed is considered as associated circuitsand subject to Class 1E requirements. The Class 1E cables and raceways and non-ClassI Ecables inside the radiologically controlled area ofthe auxiliary building are designedto be appropriately separated in accordancewith APP-GW-E1-001 (Reference 1). Installation Specifications provided totheconstructor identify separation criteria, consistent with the ITAAC commitment.
Class 1E electrical cables and raceways are installed inaccordance with design drawings, installation specifications issued for construction and work package requirements. Completed raceway installation, in-progress cable installation, and completed cableterminations are inspected to ensurethe separation installation specifications are satisfied. Inspections are performed in accordance with the Construction Quality Verification Program 26139-000-4MP-T81C-N7101 (Reference 2). The completed inspection records documentthe
U.S. Nuclear Regulatory Commission ND-18-0511 Enclosure 4 Page 3 of 3 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.
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:
For areas inside the radiologically controlled area of the auxiliary building, non-Class 1E wiring that is not separated from Class 1E or associated wiring by the minimum separation distance or by a barrieror analyzed is considered as associated circuitsand subject to Class 1E requirements.
The Cable Separation Reports (References 3 and 4) are available for NRC inspection as part of the Unit3 and Unit 4ITAAC 3.3.00.07d.v.c 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 ofall ITAAC findings and associated corrective actions.
This review found no relevant ITAAC findings associated with this ITAAC.
