U.S. Nuclear Regulatory Commission ND-19-0986 Enclosure Page 2 of 3 ITAAC Statement Design Commitment

1. The EGS provides an electrical grounding system for: (1) instrument/computer grounding; (2) electrical system grounding of the neutral points of the main generator, main step-up transformers, auxiliary transformers, load center transformers, auxiliary and onsite standby diesel generators; and (3) equipment grounding of equipment enclosures, metal structures, metallic tanks, ground bus of switchgear assemblies, load centers, motor control centers, and control cabinets. Lightning protection is provided for exposed structures and buildings housing safety-related and fire protection equipment. Each grounding system and lightning protection system is grounded to the station grounding grid.

Inspections/Tests/Analvses i) An inspection for the instrument/computer grounding system connection to the station grounding grid will be performed.

11) An inspection for the electrical system grounding connection to the station grounding grid will be performed.

ill) An inspection for the equipment grounding system connection to the station grounding grid will be performed.

iv) An inspection for the lightning protection system connection to the station grounding grid will be performed.

Acceptance Criteria i) A connection exists between the instrument/computer grounding system and the station grounding grid.

ii) A connection exists between the electrical system grounding and the station grounding grid.

iii) A connection exists between the equipment grounding system and the station grounding grid.

iv) A connection exists between the lightning protection system and the station grounding grid.

U.S. Nuclear Regulatory Commission ND-19-0986 Enclosure Page 3 of 3 ITAAC Completion Description The EGS provides an electrical grounding system for four grounding subsystems:(1)

Instrument/computer grounding;(2) electrical system grounding of the neutral points of the main generator, main step-up transformers, auxiliary transformers, load center transformers, and onslte standby diesel generators;(3) equipment grounding of equipment enclosures, metal structures, metallic tanks, ground bus of switchgear assemblies, load centers, motor control centers, and control cabinets and (4) Lightning protection Is provided for exposed structures and buildings housing safety-related and fire protection equipment. Each grounding system and lightning protection system Is grounded to the station grounding grid.

The connections to the station grounding grid for the four grounding subsections are Identified In Table 1 of drawing SV3-0000-EG-003 and SV4-0000-EG-003(References 1 and 2). Each connection Is uniquely Identified In the plan drawings. The connections to the station grounding grid are exothermic and Installed In accordance with the project specification. Each connection Is Inspected and documented In accordance with 26139-000-4MP-T81C-N3307(Reference 3).

The results of the Inspection performed at each connection to the station grounding grid for the four grounding subsections are Identified In SV3-EGS-ITR-800637 and SV4-EGS-ITR-800637 (References 4 and 5) and confirm;(1) a connection exists between the Instrument/computer grounding system and the station grounding grid;(2) a connection exists between the electrical system grounding and the station grounding grid;(3) a connection exists between the equipment grounding system and the station grounding grid, and (4) a connection exists between the lightning protection system and the station grounding grid.

List of ITAAC Findings In accordance with plant procedures for ITAAC completion. Southern Nuclear Operating Company(SNC) performed a review of all findings pertaining to the subject ITAAC and associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC.
