SUBJECT:

CONSTRUCTION REACTOR OVERSIGHT PROCESS PERFORMANCE METRIC REPORT FOR CALENDAR YEAR 2023 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) 2023 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. 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.

Vogtle Electric Generating Plant (Vogtle) Unit 4 remained under the cROP for the first half of CY 2023 but transferred to the Reactor Oversight Process (ROP) in July 2023, after staff issued the 10 CFR 52.103(g) finding based on its determination that all of the ITAAC in Appendix C of the Vogtle Unit 4 combined license were successfully met. Vogtle Unit 3 transferred to the ROP in August 2022, and is not included in this performance review for CY 2023.

James E. Gaslevic, NRR/VPO 301-415-2776

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 applicable performance metrics by meeting the acceptance criteria defined in IMC 2522 Appendix A. Four metrics were deemed not applicable for the CY 2023 self-assessment, which were related to technical assistance requests, supplemental inspections, appeals of SDP results, and significant events. In CY 2023, there were no technical assistance requests, no supplemental inspections, and no significant events for Vogtle Unit 4, and no appeals were received.

cROP SELF-ASSESSMENT METRIC REPORT INSPECTION MANUAL CHAPTER 2522 APPENDIX A CONSTRUCTION REACTOR OVERSIGHT PROCESS SELF-ASSESSMENT METRICS 2522A-01 INSPECTION PROGRAM (IP) METRICS IP-1 Inspection Reports are issued within Timeliness Requirements Met:

Yes Definition:

Audit 100 percent of reactor construction inspection reports issued during the calendar year in relation to the inspection report timeliness requirements in Inspection Manual Chapter (IMC) 0613, Power Reactor Construction Inspection Reports.

Acceptance Criteria: At least 90 percent of reactor construction inspection reports issued during the calendar year meet the inspection report timeliness requirements in IMC 0613.

Lead:

Office of Nuclear Reactor Regulation (NRR)/Vogtle Project Office (VPO)

Goals Supported:

Objective, Risk-Informed, Predictable, Effective, Open Note:

For inspections not conducted by a resident inspector, inspection completion is normally defined as the day of the final exit meeting. For resident inspector and integrated inspection reports, inspection completion is normally defined as the last day covered by the inspection report. For stand-alone team inspection reports, the report is issued no later than 45 calendar days after inspection exit.

Analysis:

All reactor construction inspection reports issued during calendar year (CY) 2023 met the timeliness requirements in IMC 0613.

2 IP-2 NRC's Response to Technical Assistance Requests (TAR) Is Timely Met:

N/A Definition:

Audit 100 percent of TARs completed in the calendar year in relation to the TAR timeliness requirements in NRR-COM-106, Revision 6, Technical Assistance Request (TAR) Process.

Acceptance Criteria: Construction TARs are expected to be completed in as timely a manner as possible in keeping with construction schedules and associated inspection and oversight. The nominal expectation for completion of construction TARs is 30 days.

Lead:

NRR/VPO Goals Supported:

Objective, Risk-Informed, Understandable, Open, Effective Analysis:

There were no TARs issued for CY 2023.

3 2522A-02 SIGNIFICANCE DETERMINATION PROCESS (SDP) METRICS SDP-1 SDP Results Are Predictable and Repeatable Met:

Yes Definition:

Audit 100 percent 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 appendixes.

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