Pursuant to 10 CFR 52.99(c)(3), Southern Nuclear Operating Company hereby notifies the NRC that as of January 21, 2020, Vogtle Electric Generating Plant (VEGP) Unit 4 Uncompleted Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 3.3.00.02f [Index Number 774] has not been completed greater than 225-days prior to initial fuel load. The Enclosure describes the plan for completing ITAAC 3.3.00.02f [Index Number 774]. 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 partially completed.

All ITAAC will be fully completed and all Section 52.99(c)(1) ITAAC Closure Notifications will be submitted to the NRC to support the Commission finding that all acceptance criteria are met prior to plant operation, as required by 10 CFR 52.103(g).

The key dimensions of nuclear island structures are defined on Table 3.3-5.

Inspections/T ests/Analvses An inspection will be performed of the as-built configuration of the nuclear island structures.

Acceptance Criteria A report exists and concludes that the key dimensions of the as-built nuclear island structures are consistent with the dimensions defined on Table 3.3-5.

ITAAC Completion Description Inspection of the as-built configuration of the nuclear island structures is conducted to confirm that the key dimensions of the as-built nuclear island structures are consistent with the dimensions defined on VEGP Unit 4 Combined License (COL) Appendix C Table 3.3-5 (Attachment A).

Inspection of the distance from bottom of containment sump to top surface of embedded containment shell key dimension is performed per ITAAC 3.3.00.09 and is documented in ITAAC Closure Notification Letter ND-14-1936, Vogtle Electric Generating Plant Unit 4 Completion of ITAAC 3.3.00.09 [Index Number 814] (Reference 1). Inspection of the site grade level relative to the design plant grade floor elevation key dimension is performed per ITAAC 3.3.00.02b and is documented in the ITAAC Completion Package for ITAAC 3.3.00.02b (Reference 2). For the remainder of the key dimensions identified in Attachment A an inspection is performed by surveying the as-built configuration of the nuclear island structures using survey equipment in accordance with site survey and measurement procedures. The results of the as-built measured dimensions are summarized in Attachment A. The as-built measured dimension inspection results are compared to the dimensions defined in Attachment A to validate that the dimensions of the as-built nuclear island structures are consistent with the dimensions defined on Attachment A.

The as-built measured dimension inspection results are documented in the Principal Closure Document XXX (Reference 3) supporting the ITAAC 3.3.00.02f Completion Package (Reference

4) and verify that the key dimensions of the as-built nuclear island structures are consistent with the dimensions defined on VEGP Unit 4 COL Appendix C Table 3.3-5.

Principal Closure Document XXX is available for NRC inspection as part of the ITAAC 3.3.00.02f Completion Package.

U.S. Nuclear Regulatory Commission ND-20-0023 Enclosure Page 3 of 4 List of ITAAC 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.
