January 4, 2022 MEMORANDUM TO: Gregory Bowman, Director Vogtle Project Office Office of Nuclear Reactor Regulation FROM: Victor Hall, Chief /RA/

Vogtle Project Office Office of Nuclear Reactor Regulation

SUBJECT:

CONSTRUCTION REACTOR OVERSIGHT PROCESS PERFORMANCE METRIC REPORT FOR CALENDAR YEAR 2021 The Construction Reactor Oversight Process (cROP) self-assessment program evaluates the effectiveness of the cROP through its success in meeting pre-established goals and intended outcomes. The staff performed the Calendar Year (CY) 2021 performance metric analysis in accordance with Inspection Manual Chapter (IMC) 2522, Construction Reactor Oversight Process Self-Assessment Program, dated July 28, 2014, and IMC 2522 Appendix A, Reactor Oversight Process Self-Assessment Metrics, dated October 4, 2017.

IMC 2522 and its appendix describe performance metrics associated with each of four cROP program areas: the inspection program (IP), significance determination process (SDP),

assessment (AS) program, and inspections, tests, analyses, and acceptance criteria (ITAAC) program (ITA). The staff designates the program-specific metrics as the IP, SDP, AS, and ITA metrics, respectively. The staff also monitors and analyzes a metric of a more general nature, which is designated as the O metric, to assess the overall performance of the cROP. provides a summary of the performance metric analysis results and Enclosure 2 provides the detailed report. The staff found that the cROP successfully met all but one applicable performance metrics by meeting the acceptance criteria defined in IMC 2522 Appendix A. The metric found not met involved rescinding previously accepted ITAAC closure notifications on the same ITAAC for both Vogtle Electric Generating Plant (Vogtle) Units 3 and 4. Three metrics were deemed not applicable for the CY 2021 self-assessment.

2522A-02 SIGNIFICANCE DETERMINATION PROCESS (SDP) METRICS SDP-1 SDP Results Are Predictable and Repeatable Met: Yes Definition: Audit 100% of construction inspection program inspection findings issued during the calendar year against the significance determination process in IMC 2519, Construction Significance Determination Process, and its appendices.

Acceptance Criteria: If greater than 10 findings were issued during the calendar year, then at least 90% of them contain adequate detail to enable an independent auditor to trace through the significance determination process in IMC 2519 and its appendices and reach the same significance color characterization.

If 10 or fewer findings were issued during the calendar year, then no more than 1 of them did not contain adequate detail to enable an independent auditor to trace through the significance determination process in IMC 2519 and its appendices and reach the same significance color characterization.

Lead: NRR/VPO Goals Supported: Risk-Informed, Predictable Note: The number of inspection findings in a calendar year are those that are issued during that calendar year, independent of the inspection report number.

Analysis: There were 21 findings (19 GREEN and 2 WHITE) documented in 2021 and reviewed through independent audit. All findings contained the necessary detail to enable the independent auditor, using IMC 2519 Construction Significance Determination Process, to obtain the same finding color characterization.
