The recorded voltage and current remain within the acceptance criteria for each IDS 72-hour battery charger. Output voltage and current are tabulated in Attachment G and demonstrate the IDS 72-hour battery chargers meet the acceptance criteria.

The Unit 3 and Unit 4 preoperational test results confirm that each IDS 72-hour battery charger provides an output current of at least 125 A with an output voltage in the range 210 to 280 V.

Each regulating transformer supplies a line-to-line output voltage of 208 +/- 2% V.

Testing is performed in accordance with Unit 3 and Unit 4 preoperational test procedures 3-IDS-ITPP-501 and 4-IDS-ITPP-501 (References 1 and 2)to confirm that each regulating transformer supplies a line-to-line output voltage of 208 +/- 2% V.

The IDS system is aligned with the division A regulating transformer powered from the 480 V Motor Control Center and supplying a distribution panel with a load bank attached to the distribution panel. The load bank is then adjusted to greater than 30 KW and the division A regulating transformer output is recorded. This testing is repeated for the remaining division inverters. The regulating transformer line to line voltages are tabulated in Attachment H.

The Unit 3 and Unit 4 preoperational test results confirm that each regulating transformer supplies a line-to-line output voltage of 208 +/- 2% V.

Safetv-related disolavs identified in Table 2.6.3-1 can be retrieved in the MCR.

An inspection is performed to verify the retrievability of the Vogtle Electric Generating Plant (VEGP) Unit 3 and Unit 4 safety-related displays in the MCR. The inspection for retrievability

U.S. Nuclear Regulatory Commission ND-19-0833 Enclosure Page 9 of 16 confirms tfiat the safety-related displays of the parameters identified in COL Appendix C Table 2.6.3-1 (Attachment I) can be retrieved in the MCR.

The inspection is performed in accordance the Unit 3 and Unit 4 component test package work orders(References 7 and 8, respectively)for IDS component indication verifications, and visually confirms that when each of the safety-related displays identified in Attachment I is summoned at the MCR Protection and Safety Monitoring System (PMS) Visual Display Units (VDUs), the summoned safety-related display appears on the PMS VDU.

The Unit 3 and Unit 4 component test results(References 7 and 8, respectively) confirm that the VEGP Unit 3 and Unit 4 safety-related displays listed in Attachment I can be retrieved in the MCR.

Displavs identified in Table 2.6.3-2 can be retrieved in the MCR.

An inspection is performed to verify the retrievability of the VEGP Unit 3 and Unit 4 plant parameters in the Main Control Room (MCR). The inspection for retrievability confirms that the displays of the parameters identified in COL Appendix C Table 2.6.3-2(Attachment J) can be retrieved in the MCR.

The inspection is performed in accordance with the Unit 3 and Unit 4 component test package work orders(References 7 and 8, respectively) for IDS component indication verifications, and visually confirms that when each of the displays of parameters identified in Attachment J is summoned at an MCR workstation, the summoned plant parameter appears on a display monitor at that MCR workstation.

The Unit 3 and Unit 4 component test results(References 7 and 8, respectively) confirm that the VEGP Unit 3 and Unit 4 plant parameter displays listed in Attachment J can be retrieved in the MCR.

References 1 through 8 are available for NRC inspection as part of Unit 3 and Unit 4 ITAAC Completion Packages(Reference 9 and 10).

List of tTAAC 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.
