U.S. Nuclear Regulatory Commission ND-18-0814 Enclosure 2 Page 1 of 3 Southern Nuclear Operating Company ND-18-0814 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.b [Index Number 804]
U.S. Nuclear Regulatory Commission ND-18-0814 Enclosure 2 Page 2 of 3 ITAAC Statement Design Commitment 7.d) Physical separation is maintained between Class1Edivisions and between Class1E divisions and non-Class 1E cables.
Inspections. Tests. Analvses Inspections of theas-built raceways that route Class 1Ecables will be performed toconfirm that the separation between raceways that route Class 1Ecablesofdifferent divisions, and between raceways that route Class 1Ecables and raceways that route non-Class 1E cables isconsistent with the following:
iii) Where minimum separation distances are not maintained, thecircuits are run in enclosed raceways or barriers are provided.
Acceptance Criteria Results of the inspection will confirm thattheseparation between raceways thatroute Class1E 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.b) Where minimum separation distances are not met inside the non-radiologically controlled area of the auxiliary building, the circuits are run in enclosed raceways or barriers 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 donot meet theseparation distance criteria of ITAAC 3.3.00.07d.ii.b may be provided byenclosed raceways or barriers. For circuits requiring enclosed raceways orbarriers, the subject ITAAC requires inspections of the raceways that route Class 1E cables and raceways that route non-Class 1E cables insidethe non-radiologically controlled areaof the auxiliary building toconfirm that circuits are run in enclosed raceways orhave barriers provided. The Class 1Ecables and raceways andnon-Class 1E cables inside the non-radiologically controlled area ofthe auxiliary building are designedto be appropriately separated in accordance with APP-GW-E1-001 (Reference 1). Installation specifications provided totheconstructor identify theseparation criteria, consistent with the ITAAC commitment.
Class 1Eelectrical cables, raceways, and barriersare installed in accordance with design drawings, installation specifications issued for construction andwork package requirements.
Completed raceway installation, in-progress and completed cable installation, completed cable terminations, and barriers are inspectedto ensure the 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 document the satisfactory separation between raceways thatroute Class1Ecablesof different divisions, and between raceways that route Class 1Ecables and raceways that route non-Class 1E cables.
U.S. Nuclear Regulatory Commission ND-18-0814 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 withthe following:
Where minimum separation distances are not maintained inside the non-radiologically controlled area of the auxiliary building, the circuits are run in enclosed raceways or barriers are provided.
Exceptionsto 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.b (Enclosure 3) or ITAAC 3.3.00.07d.v.b (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.b 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.
