MEMORANDUM TO:
Victor E. Hall, Director Vogtle Project Office Office of Nuclear Reactor Regulation Omar Lopez-Santiago, Director Division of Construction Oversight Region II FROM:
Christopher R. Welch, Senior Reactor Operations Engineer Vogtle Project Office Office of Nuclear Reactor Regulation
SUBJECT:
UPDATE TO TARGETED INSPECTIONS, TESTS, ANALYSES, AND ACCEPTANCE CRITERIA FOR VOGTLE ELECTRIC GENERATING PLANT UNIT 4 This memorandum updates the list of Inspections, Tests, Analyses and Acceptance Criteria (ITAAC) targeted for inspection by the U.S. Nuclear Regulatory Commission (NRC) under the baseline inspection program for Vogtle Electric Generating Plant (VEGP), Unit 4. The updates to ITAAC targeting incorporate the latest license amendment for VEGP, Unit 4, through license amendment 187.
This update reflects deletion of ITAAC Index Nos. 26, 83, 103, 172, 233, 263, 296, 368, 399, 878, 467, 527, 582, 687, and consolidation of ITAAC Index Nos. 789, 792, 803, 806, and 809 into ITAAC No. 800, consolidation of ITAAC Index Nos. 790, 793, 804, 807, and 810 into ITAAC No. 801 and consolidation of ITAAC Index Nos. 791, 794, 805, 808, and 811 into ITAAC No.
802. This update does not change the status of any targeted ITAAC and does not impact planned inspection activities.
The Vogtle Project Office is making these changes based upon the input from its expert panel, convened on December 1, 2022. The panel examined license amendment 187 for Unit 4.
Christopher Welch presented the ITAAC changes to the expert panel, which included James Gaslevic, Billy Gleaves, and Tanny Santos.

The following table provides a status of changes to the ITAAC in Appendix C for each combined license, from initial license issuance through the current license amendment:
APPENDIX C Vogtle Unit 4 License Amendment No.
187 Initial ITAAC Entries 875 ITAAC Entries Added 7*
Total ITAAC Entries 881 ITAAC Entries Deleted 517 ITAAC Entries Active**
364 Total ITAAC Activities 724 Targeted ITAAC Activities 272 Percent of ITAAC Activities Targeted 38%
- License Amendment 158 reused ITAAC entry 852.
The ITAAC matrix groups each ITAAC activity, into a unique ITAAC family that best represents the ITAACs specific construction activities. An ITAAC activity consists of an inspection, test, and or analysis and unique acceptance criteria. The ITAAC in the Design Control Document were broken into individual line items and assigned a unique ITAAC index number, so each individual ITAAC activity could be assigned into a single ITAAC family.
Changes to the license, such as for ITAAC consolidation, do not impact the placement of ITAAC activities into the ITAAC matrix or their families. These changes also do not impact the outcome of the prioritization process and selection for inspection (i.e., targeting). (Agencywide Documents Access and Management System Accession No. ML22334A083) dated November 29, 2022, lists the ITAAC activities sequentially by ITAAC index number and provides the official list of targeted ITAAC and their assigned ITAAC families.
The NRC performs the baseline construction inspection program using this list. Attachment 2 (ML22334A084) dated November 29, 2022, lists the ITAAC by family. The NRC will continue to inspect ITAAC activities using the inspection procedures related to the family designator as shown in attachments 1 and 2, as the baseline inspection requirement. The NRC inspection program credits previous inspections and findings for the pre-consolidated ITAAC under the consolidated ITAAC.
The NRC tracks ITAAC completion using the Construction Inspection Program Information Management System (CIPIMS). This software is limited to one family designator and one inspection status (i.e., targeted, or non-targeted) for each ITAAC entry, versus ITAAC activity. This limitation does not support ITAAC consolidation, as the software was designed for having a single ITAAC entry (i.e., index number) match a single ITAAC activity. With consolidation, a single index number may now have several ITAAC activities, each originally with its own family designator and targeted status. The staff modified CIPIMS so that the original ITAAC family is applied to all the consolidated activities for new consolidated ITAAC. Similarly, CIPIMS shows a consolidated ITAAC as targeted if any of its ITAAC activities are targeted. As a result, the ITAAC data in

CIPIMS is not always consistent with the official family assignments and targeted status for each of the specific ITAAC activities identified in the attachments.
