U.S. Nuclear Regulatory Commission ND-21-0295 Enclosure Page 2 of 5 IT AAC Statement Design Commitment 7.d) Physical separation is maintained between Class 1E divisions and between Class 1E divisions and non-Class 1E cables.

Inspections, Tests, Analyses Inspections of the as-built raceways that route Class 1E cables will be performed to 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:

ii.b) Within other plant areas (limited hazard areas), the minimum separation is defined by one of the following:

1) The minimum vertical separation is 5 feet and the minimum horizontal separation is 3 feet.
2) The minimum vertical separation is 12 inches and the minimum horizontal separation is 6 inches for raceways containing only instrumentation and control and low-voltage power cables::; 2/0 AWG. This minimum vertical separation is 3 inches for the configuration with a conduit above and crossing the open tray at an angle equal to or greater than 45 degrees.
3) The minimum vertical separation is 12 inches and the minimum horizontal separation is 6 inches between a conduit and an open configuration for low-voltage power cables greater than 2/0 AWG but not greater than 750 kcmil. The vertical separation is 3 inches if a conduit is above and crossing an open tray at an angle equal to or greater than 45 degrees.
4) For configurations that involve exclusively limited energy content cables (instrumentation and control), the minimum vertical separation is 1 inch and the minimum horizontal separation is 1 inch.
5) For configurations involving an enclosed raceway and an open raceway with low-voltage power cables, the minimum vertical separation is 1 inch if the enclosed raceway is below the open raceway.
6) For configuration involving enclosed raceways, the minimum separation is 1 inch in both horizontal and vertical directions.
7) The minimum vertical separation is 1 inch and the minimum horizontal separation is 1 inch for configurations with a non-safety conduit and a free air safety cable with low-voltage power cables and below.

U.S. Nuclear Regulatory Commission ND-21 -0295 Enclosure Page 3 of 5 Acceptance Criteria Results of the inspection will 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 :

ii .b) Within other plant areas inside the non-radiologically controlled area of the auxiliary building (limited hazard areas) , the separation meets one of the following:

1) The vertical separation is 5 feet or more and the horizontal separation is 3 feet or more.
2) The minimum vertical separation is 12 inches and the minimum horizontal separation is 6 inches for raceways containing only instrumentation and control and low-voltage power cables~ 2/0 AWG . This minimum vertical separation may be reduced to 3 inches for the configuration with a conduit above and crossing the open tray at an angle equal to or greater than 45 degrees.
3) The minimum vertical separation is 12 inches and the minimum horizontal separation is 6 inches between a conduit and an open configuration for low-voltage power cables greater than 2/0 AWG but not greater than 750 kcmil. The vertical separation may be reduced to 3 inches if a conduit is above and crossing an open tray at an angle equal to or greater than 45 degrees.
4) For configurations that involve exclusively limited energy content cables (instrumentation and control) , the minimum vertical separation is 1 inch and the minimum horizontal separation is 1 inch.
5) For configurations that involve an enclosed raceway and an open raceway with low-voltage power cables , the minimum vertical separation is 1 inch if the enclosed raceway is below the open raceway.
6) For configurations that involve enclosed raceways , the minimum vertical and horizontal separation is 1 inch.
7) The minimum vertical separation is 1 inch and the minimum horizontal separation is 1 inch for configurations with a non-safety conduit and a free air safety cable with low-voltage power cables and below.

ITAAC Determination Basis 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 . This ITAAC requires inspections of the as-built raceways that route Class 1E cables inside the non-radiologically controlled area of the auxiliary building to 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 meet the required separation distances. The Class 1E cables and raceways and non-Class 1E cables and raceways inside the non-radiologically controlled area of the auxiliary building are designed to be appropriately separated

U.S. Nuclear Regulatory Commission ND-21-0295 Enclosure Page 4 of 5 in accordance with APP-GW-E1-001 (Reference 1). Installation specifications provided to the constructor identify the separation criteria, consistent with the ITAAC commitment.

Class 1E electrical cables and raceways were installed in accordance with design drawings, installation specifications issued for construction, and work package requirements. Completed raceway installation , in-progress and completed cable installation, and completed cable terminations were inspected to ensure the separation installation specifications are satisfied.

Inspections were performed in accordance with the Construction Quality Verification Program, 26139-000-4MP-T81C-N7101 (Reference 2), or the Quality Control Inspection Program, ND-EN-VNP-020 (Reference 5). The completed inspection records document the satisfactory 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.

Additional inspections were performed and documented following completion of Class 1E raceway in each room to confirm that separation requirements 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 are met. Reference 3 identifies the inspections performed and confirms 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:

Within other plant areas inside the non-radiologically controlled area of the auxiliary building (limited hazard areas) , the separation meets one of the following:

1) The vertical separation is 5 feet or more and the horizontal separation is 3 feet or more.
2) The minimum vertical separation is 12 inches and the minimum horizontal separation is 6 inches for raceways containing only instrumentation and control and low-voltage power cables :s: 2/0 AWG. This minimum vertical separation may be reduced to 3 inches for the configuration with a conduit above and crossing the open tray at an angle equal to or greater than 45 degrees.
3) The minimum vertical separation is 12 inches and the minimum horizontal separation is 6 inches between a conduit and an open configuration for low-voltage power cables greater than 2/0 AWG but not greater than 750 kcmil. The vertical separation may be reduced to 3 inches if a conduit is above and crossing an open tray at an angle equal to or greater than 45 degrees.
4) For configurations that involve exclusively limited energy content cables (instrumentation and control) , the minimum vertical separation is 1 inch and the minimum horizontal separation is 1 inch .
5) For configurations that involve an enclosed raceway and an open raceway with low-voltage power cables , the minimum vertical separation is 1 inch if the enclosed raceway is below the open raceway.
6) For configurations that involve enclosed raceways , the minimum vertical and horizontal separation is 1 inch.
