Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 4 ITAAC Closure Notification on Completion of ITAAC 2.2.04.08a.i [Index Number 2351 Ladies and Gentlemen:
In accordance with 10 CFR 52.99(c)(1), the purpose of this letter is to notifythe Nuclear Regulatory Commission (NRC) of the completion of Vogtle Electric Generating Plant (VEGP)
Unit 4 Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.2.04.08a.i [Index Number 235] for verifying that the sum of the rated capacities recorded on the valve vendor code plates of the steam generator safety valves exceeds 8,240,000 Ib/hrper steam generator.
The closure process for this ITAAC is based on the guidance described in 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 10 CFR 52.99.
If there are any questions, please contact Tom Petrak at 706-848-1575.
Respectfully submitted.

U.S. Nuclear Regulatory Commission ND-18-0114 Enclosure Page 2 of 4 ITAAC Statement Desion Commitment:
S.a) The SGS provides a heat sink for the RCS and provides overpressure protection in accordance with Section III of the ASME Boiler and Pressure Vessel Code.
Inspections. Tests. Analvses:
i) Inspections will be conducted to confirm that the value of the vendor code plate rating of the steam generator safety valves is greater than or equal to system relief requirements.
Acceptance Criteria:
i) The sum of the rated capacities recorded on the valve vendor code plates of the steam generator safety valves exceeds 8,240,000 Ib/hr per steam generator.
ITAAC Determination Basis Multiple inspections, tests and analysis (ITAAC) are performed to verify that the Steam Generator System (SGS) provides a heat sink for the Reactor Coolant System (RCS) and provides overpressure protection in accordancewith Section III ofthe American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. This ITAAC requiresan inspection to confirm thatthe sum of the rated capacities recorded on the valve vendor code plates ofthe steam generator safety valves exceeds 8,240,000 Ib/hr per steam generator.
An inspection ofthe ASME Code Datafor the steam generatorsafetyvalves listed in the Combined License (COL) Appendix C, Table 2.2.4-1 (Attachment A) was performed (Reference 2).
The ratedcapacities recorded on the ASME NV-2 Code plates ofthe safetyvalveswere summed and exceed 8,240,000 Ib/hr per set of valves for each steam generator. The steam generator safety valve flow capacity recorded onthe valve ASME Code plate was certified by ASME through the National Board of Boiler and Pressure Vessel Inspectors (NBBPVI). Article NC-7700 of the ASME Boiler and Pressure Vessel Code,Section III (Reference 1) describes the methods required to certify the relief device capacity and determine a coefficient used in determining capacity in subsequently manufactured valves. The safety valve flow capacity for the steamgenerator safety valves was calculated bya set ofequations using the coefficient found in NC-7700 and also in NB-18, "Pressure Relief Device Certification" from the NBBPVI.
The ASME Code data plateforeach steam generatorsafety valve recordsthe rated capacity based on the set pressures as shown in Attachment A. The sum ofthe ratedcapacities recorded on the valve vendor code plates of the steam generator safety valves is 10,937,764 Ib/hr for each steam generator which exceeds 8,240,000 Ib/hr per steam generator and meets the \\7AAC acceptance criteria.
U.S. Nuclear Regulatory Commission ND-18-0114 Enclosure Page 3 of 4 ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performeda review of all ITAAC findings pertaining to the subject ITAAC and associated corrective actions. This review found that there are no relevant ITAACfindings associated with this ITAAC. The ITAAC completion review is included in the Vogtle Unit4 ITAAC Completion Package for ITAAC 2.2.04.08a.i (Reference 3) and available for NRC inspection.
ITAAC Completion Statement Based on the above information, SNC hereby notifiesthe NRCthat ITAAC 2.2.04.08a.i was performed forVEGP Unit 4 that the prescribed acceptance criteria are met.
Systems, structures, andcomponents verified as part of this ITAAC are being maintained in their as-designed, ITAAC compliant condition in accordance with approved plant programs and procedures.
