Coleman Regulatory Affairs Director Vogtle 3 & 4 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 7825 River Road Waynesboro, GA 30830 706-848-6926 tel ND-22-0255 10 CFR 52.99(c)(1)
ITAAC Closure Notification on Completion of ITAAC 2.6.03.04i (Index Number 609]
Ladies and Gentlemen:
In accordance with 1 O CFR 52.99(c)(1 ), the purpose of this letter is to notify the Nuclear Regulatory Commission (NRC) of the completion of Vogtle Electric Generating Plant (VEGP) Unit 3 Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.6.03.04i (Index Number 609].
This ITAAC confirms that the Class 1 E DC and Uninterruptible Power Supply System (IDS) supplies an operating voltage at the terminals of the specified Class 1 E motor operated valves that is greater than or equal to the minimum design voltage. The closure process for this ITAAC is based on the guidance described in Nuclear Energy Institute (NEI) 08-01, "Industry Guideline for the ITAAC Closure Process under 10 CFR Part 52," which was endorsed by the NRC in Regulatory Guide 1.215.
This letter contains no new NRC regulatory commitments. Southern Nuclear Operating Company (SNC) requests NRC staff confirmation of this determination and publication of the required notice in the Federal Register per 1 O CFR 52.99.
If there are any questions, please contact Kelli Roberts at 706-848-6991.
Respectfully submitted,
~m~
Regulatory Affairs Director Vogtle 3 & 4

U.S. Nuclear Regulatory Commission ND-22-0255 Enclosure Page 2 of 6 IT AAC Statement Design Commitment 4.i) The IDS supplies an operating voltage at the terminals of the Class 1 E motor operated valves identified in subsections 2.1.2, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.3.2, 2.3.6, and 2.7.1 that is greater than or equal to the minimum design voltage.
Inspections/Tests/ Analyses Testing will be performed by measuring the voltage during motor starting at both the IDS battery and motor-operated valve motor terminals while each motor-operated valve is stroked. Analyses will be performed to verify that the voltage at the motor-operated valve motor terminals is greater than or equal to the minimum design voltage of each motor-operated valve with an IDS battery terminal voltage of 21 0 Vdc.
Acceptance Criteria A report exists and concludes that IDS can provide a voltage greater than or equal to each valve's minimum design voltage to the motor terminals of each motor-operated valve when power is supplied under design conditions from IDS batteries with battery terminal voltage at 210 Vdc while each motor-operated valve is stroked.
ITAAC Determination Basis Testing was performed by measuring the voltage during motor starting at both the Class 1 E DC and Uninterruptible Power Supply system (IDS) battery and motor-operated valve (MOV) motor terminals while each MOV is stroked. Analyses were performed to verify that the voltage at the MOV motor terminals is greater than or equal to the minimum design voltage of each MOV with an IDS battery terminal voltage of 21 0 Vdc.
Analyses were performed in accordance with SV3-IDS-E0C-004 (Reference 1) to determine the voltage drop on each power circuit at a battery voltage of 21 0 Vdc and the resulting voltage at the MOV terminals during normal operating conditions, and accident conditions. Reference 1 is the basis of analyses performed in accordance with SV3-IDS-E0C-018 (Reference 2). The analyses determined the expected voltage at the MOV terminals and defined the method for the determination of the minimum acceptance voltage for each MOV during preoperational testing.
Each MOV identified in Combined License (COL) Appendix C, Subsections 2.1.2, 2.2.1,2.2.2, 2.2.3, 2.2.4, 2.3.2, 2.3.6, and 2.7.1 (Attachment A) was stroked individually as documented in SV3-IDS-E0R-005 (Reference 3). The voltage at the battery terminals and at the MOV terminals was recorded during MOV operation using installed maintenance and test equipment. The recorded voltage at the MOV terminals was analyzed in accordance with the method described in Reference 2, to compare proportional values when the tested battery voltage is higher or lower than the nominal voltage assumed in the analyses of Reference 2, to determine the minimum acceptance voltage for each MOV. A resulting proportional voltage that is greater than or equal to the minimum design voltage of each MOV confirms the tested voltage is bounded by the analyses in Reference 2.
U.S. Nuclear Regulatory Commission ND-22-0255 Enclosure Page 3 of 6 The analyses and preoperational test results (References 1 through 3) confirmed that IDS can provide a voltage greater than or equal to each MOV's minimum design voltage to the terminals of each MOV, as specified in Reference 2, when power is supplied under design conditions from IDS batteries with battery terminal voltage at 21 0 Vdc while each MOV is stroked.
References 1 through 3 are available for NRC inspection as part of Unit 3 ITAAC Completion Package (Reference 4).
ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all lTAAC findings pertaining to the subject ITAAC and associated corrective actions. This review found there were no relevant findings associated with this ITAAC. The review is documented in the ITAAC 2.6.03.04i Completion Package (Reference
- 4) and is available for NRC review.
IT AAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.6.03.04i was performed for VEGP Unit 3 and the prescribed acceptance criteria was met.
Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed, ITAAC compliant condition in accordance with approved plant programs and procedures.
