Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 and Unit 4 Notice of Uncompleted ITAAC 225-davs Prior to Initial Fuel Load Item 2.1.02.12a.iv [Index Number 561 Ladies and Gentlemen:
Pursuant to 10 CFR 52.99(c)(3), Southern Nuclear Operating Company hereby notifies the NRC that as of February 27, 2018, Vogtle Electric Generating Plant (VEGP) Unit 3 and Unit 4 Uncompleted Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.1.02.12a.iv
[Index Number 56] 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.
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 partiallycompleted.
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.

U.S. Nuclear Regulatory Commission ND-18-0293 Enclosure Page 2 of 5 ITAAC Statement Design Commitment 12.a) The automatic depressurization valves identified in Table 2.1.2-1 perform an active safety-related function to change position as indicated in the table.
Inspections. Tests. Analvses iv) Tests or type tests of squib valves will be performed that demonstrate the capabilityof the valve to operate under its design conditions.
v) Inspection will be performedforthe existence of a report verifying that the as-builtsquib valves are bounded by the tests or type tests.
Acceptance Criteria iv) Atest report exists and concludesthat each squibvalvechanges position as indicated in Table 2.1.2-1 under design conditions.
v) A report exists and concludesthat the as-built squib valvesare boundedbythe tests or type tests.
ITAAC Completion Description Multiple Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) are performed to demonstrate that the Reactor Coolant System (RCS) automaticdepressurization (squib) valves identified in the Combined License(COL) Appendix C, Table 2.1.2-1 perform an activesafety-related function to change positionas indicated inthe table.
ivi A test report exists and concludes that each souib valve chances position as indicated in Table 2.1.2-1 under design conditions.
This acceptance criteria requires tests ortypetests ofsquibvalves to be performed to demonstrate the capability ofthe valveto operate under its design conditions.
Thefunctional qualification program for the API000 squib valves isdeveloped based on American Society ofMechanical Engineers (ASME) QME-1-2007, "Qualification ofActive Mechanical Equipment Used in Nuclear Power Plants" (Reference 1). Thequalification was based on the ASME QME-1-2007 requirements for power operated valve assemblies.
Functional qualification is performed underthe designconditions identified in the design specification for thevalves (Reference 2) todemonstrate thateachsquib valve isqualified to perform its designated function when used in its intended service. In accordance with ASME QME-1-2007, qualification issubstantiated bydemonstrating the relationship between the service requirements and the type-testing and analysis thatwas conducted as partof this qualification program.
Type testing isperformed, including natural frequency determination, sealing capability testing, functional operation, andflow characteristics, for the ranges of the pressure, temperature and
U.S. Nuclear Regulatory Commission ND-18-0293 Enclosure Page 3 of 5 flow for each valve. In accordance with ASME QME-1-2007, the functional qualification process for these valves also included valve internal inspections, actuator inspection and testing, orientation requirements, leakage limitations, diagnostic data collection and analysis methods, static and dynamic flow diagnostic testing, and thermal binding evaluations.
The results of the qualification are documented in the Equipment Qualification (EG) Reports (Reference 3) which are identified in Attachment A for each applicable valve. These reports summarize the test methodology and ASME QME-1-2007 functional qualification that demonstrate that each squib valve changes position as indicated inVEGP Unit3 and Unit4 COL Appendix C Table 2.1.2-1 under design conditions.
v1 A report exists and concludes that the as-built souib valves are bounded bv the tests or type tests.
This acceptance criteria requires that an inspection is performedfor the existence of a report verifying that the as-built squib valves are bounded by tests or type tests.
The squib valves inVEGP Unit 3 and Unit 4 COL Appendix C Table 2.1.2-1 are verified bythe typetests in accordance with ITAAC 2.1.02.12a.iv (above) to demonstratethe capability ofthe valvesto operate under their design conditions. The EQ Reports inAttachment A identify the equipment mounting employed for the testing and the specific conditions tested.
In accordance with the EQ Walkdown Inspection ITAAC Guideline (Reference 4), an inspection is conducted of the RCS to confirm the satisfactory installation of the squib valves. The inspection includes verification ofequipment make/model/serial number, verification of equipmentmounting and location, and verification that the mechanical and electrical connections are bounded by the tested conditions.
The documentation of installed configuration ofthe squib valves includes photographs and/or sketches ofequipment mounting and connections. The verification of installed component configuration isdocumented in the EQ As-Built Reconciliation Report(s) (EQRR) (Reference 5).
AttachmentA identifies the EQRRwhich verify that the installedconfiguration of the squib valves identified inVEGP Unit 3 and Unit 4 COLAppendix 0 Table 2.1.2-1 are bounded by the tests or type tests.
Together, these EQ Reports and EQRR (References 3and5), provide evidence thatthe ITAAC Acceptance Criteria requirements are met:
Atest report existsand concludes that each squib valve changes position as indicated in Table 2.1.2-1 under design conditions; and A report exists and concludesthat the as-built squibvalvesare bounded bythe tests or type tests.
