U.S. Nuclear Regulatory Commission ND-19-1011 Enclosure Page 2 of 3 ITAAC Statement Desion Commitment:

1. A minimum of one offsite circuit supplies electric power from the transmission network to the interface with the onsite alternating current (ac) power system.

Inspections. Tests. Analyses:

Inspections of the as-buiit offsite circuit will be performed.

Acceptance Criteria:

At least one offsite circuit is provided from the transmission switchyard interface to the interface with the onsite ac power system.

ITAAC Determination Basis An inspection of the Offsite Power System was conducted by physical walk down of the as-built circuit installed from the transmission switchyard interface to the interface with the onsite ac power system. This circuit runs from the Vogtle Unit 4 Main Step-up Transformer to the Vogtle Unit 3&4 SOOkV switchyard. The inspection team conducted a thorough review of the as-built Unit 4 SOOkV output line to assure that the line meets design specifications in accordance with Georgia Power Corporation Bulletin # 2-01, "Transmission Line Inspections for New Construction"(Reference 1). This visual inspection, as documented in the inspection report, verified that the as-built SOOkV output line, and its 3 supporting structures, were installed per design.

Inspection report"U4 ITAAC C.2.6.12.01 (671) Offsite Power Inspection Report"(Reference 2) documents the inspection and concludes that at least one offsite power circuit is provided from the transmission switchyard interface to the interface with the onsite ac power system.
