U.S. Nuclear Regulatory Commission ND-18-0817 Enclosure 4 Page 1 of 3 Southern Nuclear Operating Company ND-18-0817 Vogtle Electric Generating Plant (VEGP) Unit3 and Unit4 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-18-0817 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.
Inspections. Tests. Analvses Inspections ofthe as-built raceways that route Class 1Ecables will be performed to confirm that the separation between raceways that routeClass 1E cables ofdifferent divisions, and between racewaysthat routeClass 1Ecables and racewaysthat routenon-Class1Ecables is consistent with the following:
v) Non-Class 1E wiring that is notseparated from Class 1E or associated wiring bythe minimum separation distanceor bya barrier or analyzed is considered as associated circuits and subject to Class 1E requirements.
Acceptance Criteria Results ofthe inspection will confirm that the separation between raceways that routeClass 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) Forareas inside the radiologically controlled area ofthe auxiliary building, non-Class1E wiring that is notseparated from Class 1Eor associated wiring bythe minimum separation distance or by a barrier or 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 Ciass 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 separationdistance and forwhich no barrier or analysis is provided is consideredas associated circuits and subject to Class 1E requirements. The subject iTAAC requires inspections ofthe Class1Eand non-Class 1Eraceways inside the radiologically controlled area ofthe auxiliary building to confirm that non-Class 1Ewiring that is notseparated from Class 1E or associated wiring bythe minimum separationdistance or bya barrier or analyzed is considered as associated circuits and subject to Class 1E requirements. The Class 1E cables and raceways and non-Class1 Ecables inside the radiologically controlled area ofthe auxiliary building are designed to be appropriately separated in accordance with APP-GW-E1-001 (Reference 1). Installation specifications provided to the constructor identify separation criteria, consistent with the ITAAC commitment.
Class 1E electrical cables and raceways are installed in accordance with design drawings, installation specifications issuedfor construction and work package requirements. Completed raceway installation, in-progress and completed cable installation, and completed cable terminations are inspected to ensure the separation installation specifications are satisfied.
Inspectionsare performed inaccordance with the Construction Quality Verification Program 26139-000-4MP-T81C-N7101 (Reference 2). The completed inspection records document the
U.S. Nuclear Regulatory Commission ND-18-0817 Enclosure 4 Page 3 of 3 satisfactory separation between raceways thatroute Class1Ecables of different divisions, and between raceways that route Class 1Ecables and raceways that route non-Class 1Ecables.
Cable Separation Reports XXX (References 3 and 4) identify the inspection reports associated with the raceway separation inspections and 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:
Forareas inside the radiologically controlled area ofthe auxiliary building, non-Class1Ewiring that is notseparated from Class 1Eorassociated wiring bythe minimum separation distanceor bya barrier oranalyzed isconsidered as associated circuits and subject to Class 1E requirements.
TheCable Separation Reports (References 3 and 4)are available for NRC inspection as partof the Unit3 and Unit4ITAAC 3.3.00.07d.v.c Completion Packages (References 5 and 6, respectively).
List of ITAAC Findings In accordance with plantprocedures for ITAAC completion. Southern Nuclear Operating Company (SNC) performed a review of all ITAAC findings and associated corrective actions.
This reviewfound no relevant ITAAC findings associated withthis ITAAC.
