U.S. Nuclear Regulatory Commission ND-18-0511 Enclosure 2 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.iii.c [Index Number 805]
U.S. Nuclear Regulatory Commission ND-18-0511 Enclosure 2 Page 2 of 3 ITAAC Statement Desion 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 of theas-built raceways that route Class1Ecableswill be performed to confirm that the separation between raceways that route Class 1Ecablesofdifferent divisions, and between raceways that route Class1Ecables and raceways that route non-Class 1Ecablesisconsistent with the following:
iii) Where minimum separation distances are not maintained, thecircuits are run in enclosed raceways or barriers are provided.
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:
iii.c) Where minimum separation distances are not met inside the radiologically controlled area of the auxiliary building, thecircuits are run in enclosed raceways orbarriers are provided.
ITAAC Completion Description Multiple ITAAC are performed toensure that physical separation ismaintained between Class 1E divisions and between Class 1E divisions and non-Class 1E cables. Inaccordance withthis ITAAC, physical separation for circuits that do not meet theseparation distance criteria of ITAAC 3.3.00.07d.ii.c may be provided by enclosed raceways orbarriers. For circuits requiring enclosed raceways or barriers, the subject ITAAC requires inspections of the raceways that route Class 1Ecables and raceways that route non-Class 1Ecables inside the radiologically controlled area ofthe auxiliary building to confirm that circuits are run inenclosed racewaysor have barriers provided. The Class 1Ecables and raceways andnon-ClassI Ecables inside the radiologically controlled areaof the auxiliary building are designed to beappropriately separated in accordancewith APP-GW-E1-001 (Reference 1). Installation Specifications provided to the constructor identify the separationcriteria, consistentwith the ITAAC commitment.
Class 1E electrical cables and racewaysare installed in accordance with design drawings, installation specifications issued for construction andwork package requirements. Completed raceway installation, in-progress cable installation, andcompleted cable terminations are inspected toensuretheseparation installation specifications are satisfied. Inspections are performed in accordance with the Construction Quality Verification Program 26139-000-4MP-T81C-N7101 (Reference2).The completed inspection recordsdocument the satisfactory separation between raceways that route Class 1E cables of different divisions, and between raceways that route Class1Ecables and raceways thatroute non-Class 1Ecables.
U.S. Nuclear Regulatory Commission ND-18-0511 Enclosure 2 Page 3 of 3 Cable Separation Reports XXX (References 3 and 4) identifythe 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 the radiologically controlled area of the auxiliary building, 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 withinthe scope of ITAAC 3.3.00.07d.iv.c (Enclosure 3) or ITAAC 3.3.00.07d.v.c (Enclosure 4).
The Cable Separation Reports (References 3 and 4) are available for NRC inspection as part of the Unit3 and Unit4 ITAAC 3.3.00.07d.iii.c Completion Packages (References 5 and 6, respectively).
List of ITAAC Findings In accordance with plant procedures for ITAAC completion. Southern Nuclear Operating Company (SNC) performeda review of all ITAAC findings and associated correctiveactions.
This review found no relevant ITAAC findings associated with this ITAAC.
