U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 and Unit 4 Resubmittal Notice of Uncompleted ITAAC 225-davs Prior to Initial Fuel Load Item 2.5.02.10 (Index Number 5491 Ladies and Gentlemen:

Pursuant to 10 CFR 52.99(c)(3), Southern Nuclear Operating Company hereby notifies the NRC that as of October 16, 2019, Vogtle Electric Generating Plant(VEGP) Unit 3 and Unit 4 Uncompleted Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.5.02.10 [Index Number 549] has not been completed greater than 225-days prior to initial fuel load. The Enclosure describes the plan for completing this ITAAC. Southern Nuclear Operating Company will, at a later date, provide additional notifications for ITAAC that have not been completed 225 days prior to initial fuel load.

Southern Nuclear Operating Company(SNC) previously submitted Notice of Uncompleted ITAAC 225 days Prior to Initial Fuel Load for Item 2.5.02.10 [Index Number 549] ND-19-0137

[ML19073A263] dated March 14, 2019. This resubmittal supersedes ND-19-0137 in its entirety.

This notification is informed by 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. In accordance with NEI 08-01, this notification includes ITAAC for which required inspections, tests, or analyses have not been performed or have been only partially completed. All ITAAC will be fully completed and all Section 52.99(c)(1) ITAAC Closure Notifications will be submitted to NRC to support the Commission finding that all acceptance criteria are met prior to plant operation, as required by 10 CFR 52.103(g).

This letter contains no new NRC regulatory commitments.

If there are any questions, please contact Tom Petrak at 706-848-1575.

Respectfully submitted.

10. Setpolnts are determined using a methodology which accounts for loop inaccuracies, response testing, and maintenance or replacement of instrumentation.

InsDectlons/Tests/Anaivses inspection will be performed for a document that describes the methodology and input parameters used to determine the RMS setpoints.

Acceptance Criteria A report exists and concludes that the RMS setpoints are determined using a methodology which accounts for loop inaccuracies, response testing, and maintenance or replacement of instrumentation.

ITAAC Determination Basis This ITAAC requires that inspection be performed to verify that the Protection and Safety Monitoring System (RMS)setpoints are determined using a methodology which accounts for loop inaccuracies, response testing, and maintenance or replacement of instrumentation.

Results of the inspections noted below are documented in 2.5.02.10-U3-SumRep-Rev X,"Unit 3 Protection and Safety Monitoring System Setpoint Methodology Summary Report"(Reference

1) and 2.5.02.10-U4-SumRep-Rev X,"Unit 4 Protection and Safety Monitoring System Setpoint Methodology Summary Report"(Reference 2)for Units 3 and 4, respectively.

WCAP-16361-P,"Westinghouse Setpoint Methodology for Protection Systems- API000" (Reference 3), was inspected and identifies the methodology used to determine the overall instrument uncertainty (i.e. loop inaccuracy) for a Reactor Trip System (RTS)and Engineered Safeguards Features Actuation System (ESFAS)function. Reference 3 provides specific instructions for calculating instrument and loop uncertainty setpoints consistent with ANSI/ISA-67.04.01-2000 and Regulatory Guide 1.105, Revision 3. An inspection of the RTS/ESFAS function setpoint and uncertainty calculations was performed and confirmed calculations employ the WCAP-16361-P methodology to determine loop inaccuracies, as documented in references 1 and 2.

Section 5.5.14 of the API000 Technical Specifications(TS) requires the nominal trip setpoint, As-Found Tolerance (AFT), and As-Left Tolerance (ALT)for each TS-required automatic protection instrumentation function be calculated in conformance with WCAP-16361-P. These requirements are used to determine if maintenance or replacement of instrumentation is needed. If maintenance or replacement is required, the "Operational Readiness Work Management" procedure (Reference 4), and "Plant Modification and Configuration Change Processes"(Reference 5), accounts for any impacts on instrumentation or issued calculations.

An inspection of the RTS/ESFAS function setpoint and uncertainty calculations was performed

U.S. Nuclear Regulatory Commission ND-19-1311 Enclosure Page 3 of 11 and confirmed calculations employed the WCAP-16361-P methodology for AFT and ALT, as documented in references 1 and 2.

The methodology utilized for response time determination is per UFSAR Chapter 15 criteria (Reference 6). Response testing is conducted within the factory acceptance and preoperational test program per UFSAR Chapter 14(Reference 6). UFSAR section 15.0.6 (Reference 7),

discusses the PMS time delay methodology that Is assumed in the accident analysis for RTS and equipment actuated by ESFAS functions. An inspection of SV3-PMS-T1-501,"AP1000 Protection and Safety Monitoring system Preoperational and Component Test Specification" and SV4-PMS-T1-501,"API000 Protection and Safety Monitoring system Preoperational and Component Test Specification"(References 7 and 8) and APP-PMS-T5-001,"Protection and Safety Monitoring System Test Plan"(Reference 9), was performed to confirm that the PMS preoperational test program includes the response time testing as required. Attachment A provides a cross-reference of each applicable PMS function to its test case.

References 1 through 9 are available for NRC inspection as part of Unit 3 and Unit 4 ITAAC 2.5.02.10 Completion Packages(Reference 13 and 14, respectively).

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