Pursuant to 10 CFR 52.99(c)(3), Southern Nuclear Operating Company hereby notifies the NRC that as of April 11, 2019, Vogtle Electric Generating Plant(VEGP) Unit 3 and IJnit 4 Uncompleted Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 3.3.00.02a.ii.e [Index Number 768] 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 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.

U.S. Nuclear Regulatory Commission ND-19-0390 Enclosure Page 2 of 7 ITAAC Statement Desion Commitment 2.a) The nuclear island structures, including the critical sections listed in Table 3.3-7, are seismic Category I and are designed and constructed to withstand design basis loads as specified in the Design Description, without loss of structural integrity and the safety-related functions.

Insoections/Tests/Analvses ii) An inspection of the as-built concrete thickness will be performed.

Acceotance Criteria ii.e) A report exists that concludes that the as-built concrete thicknesses of the annex building sections conform with the building sections defined in Table 3.3-1.

ITAAC Completion Description Multiple ITAAC are performed to verify the nuclear island structures, including the critical sections listed in Combined License(COL) Appendix C, Table 3.3-7, are seismic Category I and are designed and constructed to withstand design basis loads as specified in the Design Description, without loss of structural integrity and the safety-related functions. The subject ITAAC requires that an inspection be performed and documented in a report that concludes that the as-built annex building sections concrete wall thicknesses conform with the building sections defined in COL Appendix C,Table 3.3-1 (Attachment A).

The inspections are performed of the as-built sections (following concrete placement) in accordance with the requirements of measurement guideline APP-GW-IT-001 (Reference 1),

which identifies the location and frequency of inspection points for determining wall thickness to ensure the resulting measurements are representative of the entire section being inspected.

The measurements are based on the size and construction type of each section.

Measurements are taken using survey equipment in accordance with site survey procedures (Reference 2).

The inspection results contained in the Unit 3 and Unit 4 principal closure documents (References 3 and 4, respectively) and summarized in Attachment A conclude that the as-built concrete thicknesses of the annex building sections conform with the building sections defined in ITAAC Table 3.3-1.

References 1 thru 4 are available for NRG inspection as part of the Unit 3 and Unit 4 ITAAC 3.3.00.02a.ii.e Completion Packages(Reference 5 and 6, respectively).

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

U.S. Nuclear Regulatory Commission ND-19-0390 Erurfosure Page 3 of 7 associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC.

U.S. Nuclear Regulatory Commission ND-19-0390 Enclosure Page 7 of 7 Notes:

-I- Inspection results are Unit specific

• Excerpt from COL Appendix C, Table 3.3-1

1. The column lines and floor elevations are identified and included on Figures 3.3-1 through 3.3-13.

2. These wall(and floor)thicknesses have a construction tolerance of +/- 1 Inch, except as noted and for exterior walls below grade where the tolerance is +12 inches, -1 inch. These tolerances are not applicable to the nuclear island basemat.

3. For walls that are part of structural modules, the concrete thickness also Includes the steel face plates. Where faceplates with a nominal thickness of 0.5 inches are used in the construction of the wall modules,the wall thicknesses in this column apply. Where faceplates thicker than the nominal 0.5 inches are used in the construction of the structural wall modules, the wall thicknesses in the area of the thicker faceplates are greater than indicated in this column by the amount of faceplate thickness increase over the nominal 0.5 Inches.

Overlay plates are not considered part of the faceplates, and thus are not considered in the wall thicknesses identified in this column.

4. For floors with steel surface plates, the concrete thickness also includes the plate thickness.

5. Where a wall(or a floor) has openings,the concrete thickness does not apply at the opening.

6. The Wall or Section Description, Column Line information, and Floor Elevation or Elevation Ranges are provided as reference points to define the general location. The concrete thickness of an item intersecting other walls, roofs or floors at a designated location (e.g.,

column line) is not intended to be measured to the stated column line, but only to the point where the intersection occurs.

7. Where applicable, the upper wall portions extend to their associated roofs, which may vary in elevation, e.g., sloped roofs.

8. From one wall/floor section to another,the concrete thickness transitions from one thickness to another, consistent with the configurations in Figures 3.3-1 through 3.3-14.

9. The concrete thickness is the total floor thickness, including the metal decking, where applicable.

10. The concrete in the kitchen and restroom areas is 2 inches thinner.
