U.S. Nuclear Regulatory Commission ND-18-0500 Enclosure 2 Page 1 of 3 Southern Nuclear Operating Company ND-18-0500 Vogtle Electric Generating Plant (VEGP) Unit3 and Unit4 Docket No.: 52-025 & 52-026 Completion Planfor Uncompleted ITAAC 3.3.00.07d.iii.b [Index Number 804]
U.S. Nuclear Regulatory Commission ND-18-0500 Enclosure 2 Page 2 of 3 ITAAC Statement Desion Commitment 7.d) Physical separation Is maintained between Class 1E divisions andbetween Class 1E divisions and non-Class 1E cables.
Insoectlons. Tests. Analvses Inspections of theas-bullt raceways that route Class 1E cables will be performed toconfirm that theseparation between raceways thatroute Class 1Ecables 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) Where minimum separation distances arenot maintained, the circuits are run In enclosed raceways or barriers are provided.
Acceotance 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:
lll.b) Where minimum separation distances are not met Inside the non-radlologlcally controlled area of theauxiliary building, thecircuits are run In enclosed raceways orbarriers are provided.
ITAAC ComDietion Description Multiple ITAAC are performed toensure that physical separation Is maintained between Class 1E divisionsand between Class 1E divisionsand non-Class 1E cables. Inaccordance with this ITAAC, physical separation for circuits that do not meet theseparation distance criteria of ITAAC 3.3.00.07d.ll.b may be provided by enclosed raceways orbarriers. For circuits requiring enclosed raceways orbarriers, thesubject ITAAC requires Inspections of the raceways that route Class 1E cables and raceways that route non-Class 1E cables Insidethe non-radlologlcally controlled areaof theauxiliary building toconfirm that circuits are run In enclosed raceways orhave barriers provided. The Class 1E cables and raceways and non-Class 1E cables Inside the non-radlologlcally controlled area of the auxiliary building are designed to be appropriately separated In accordance with APP-GW-E1-001 (Reference 1). Installation Specifications provided totheconstructor Identify the 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 work package requirements. Completed raceway Installation, In-progress cable Installation, andcompleted cable terminations are Inspected toensure theseparation Installation specifications are satisfied. Inspections are performed In accordancewith the Construction Quality Verification Program 26139-000-4MP-T81C-N7101 (Reference 2).The completed Inspection records document the satisfactory separation between raceways that route Class 1E cables of different divisions, and between raceways thatroute Class1Ecables and raceways thatroute non-Class 1Ecables.
U.S. Nuclear Regulatory Commission ND-18-0500 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 with the 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.
Exceptions to 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 Unit 3 and Unit 4 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 reviewof all ITAAC findings and associated corrective actions.
This review found no relevant ITAAC findings associated with this ITAAC.
