U.S. Nuclear Regulatory Commission ND-18-0500 Enclosure 4 Page 2 of 3 ITAAC Statement Desion Commitment 7.d) Physical separation ismaintained between Class 1E divisions and between Class 1E divisions and non-Class 1E cables.
Insoections. Tests. Analvses Inspections of the as-built raceways that route Class 1E cables will beperformed to confirm that theseparation 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) Non-Class 1E wiring that isnot separated from Class 1E orassociated wiring by the minimum separation distance or by a barrier or analyzed isconsidered as associated circuits and subject to Class 1E requirements.
Acceotance Criteria Results of the inspection will confirm that theseparation between raceways that route Class 1E cables of differentdivisions, and between raceways that route Class 1E cables and raceways that route non-Class 1E cables is consistent with the following:
v.b) For areasinside the non-radiologically controlled areaof theauxiliary building, non-Class 1E wiring that isnot separated from Class 1E orassociated wiring by the minimum separation distance or bya 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 Class 1E divisions and non-Class 1E cables. In accordance with this ITAAC, non-Class 1Ewiring thatisnot separated from Class1Eorassociated wiring by the minimum separation distance andfor which no barrier oranalysis isprovided isconsidered as associated circuits and subjectto Class 1E requirements. The subject ITAAC requires inspections of the Class 1E and non-Class 1E raceways inside the non-radiologically controlled area ofthe auxiliary building toconfirm thatnon-Class 1Ewiring thatis not separatedfrom Class1Eorassociated wiring by the minimum separation distance or by a barrier oranalyzed is consideredas associated circuits and subjectto Class 1E requirements. The Class 1Ecables and raceways andnon-Class 1E cables inside the non-radiologically controlled area of the auxiliary building are designed to beappropriately separated in accordance with APP-GW-E1-001 (Reference 1). Installation Specifications provided totheconstructor identify separation criteria, consistent with the ITAAC commitment.
Class 1Eelectrical cables and racewaysare 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 aresatisfied. Inspections are performed in accordance with the Construction Quality Verification Program 26139-000-4MP-T81C-N7101 (Reference 2).Thecompleted inspection records document the
U.S. Nuclear Regulatory Commission ND-18-0500 Enclosure 4 Page 3 of 3 satisfactory separation between raceways that route Class 1Ecables ofdifferent divisions, and between racewaysthat route Class 1Ecables and racewaysthat routenon-Class1E cables.
Cable Separation Reports XXX (References3 and 4) identify the inspection reportsassociated with the raceway separation inspections and confirm that the separation between racewaysthat 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 insidethe non-radiologically controlled area ofthe auxiliary building, non-Class 1E wiring that is notseparated from Class 1E orassociated wiring bythe minimum separation distanceor bya barrier or analyzed isconsidered as associated circuits and subjectto Class 1E requirements.
The CableSeparation Reports(References3 and 4) are available for NRC inspection as part of the Unit3 and Unit4ITAAC 3.3.00.07d.v.b 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 of all ITAAC findings and associated corrective actions.
This review found no relevant ITAAC findings associated with this ITAAC.
