UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 11, 2024 MEMORANDUM TO:

Pat Finney, Chief Reactor Assessment Branch Division of Reactor Oversight Office of Nuclear Reactor Regulation FROM:

David M. Aird, Reactor Operations Engineer /RA/

Reactor Assessment Branch Division of Reactor Oversight Office of Nuclear Reactor Regulation

SUMMARY

OF THE REACTOR OVERSIGHT PROCESS BIMONTHLY PUBLIC MEETING HELD ON MARCH 26, 2024 On March 26, 2024, the U.S. Nuclear Regulatory Commission (NRC) staff hosted a public meeting with the Nuclear Energy Institutes (NEIs) Reactor Oversight Process (ROP) Task Force executives, other senior industry executives, and various external stakeholders to discuss the staffs progress on initiatives related to the ROP. The topics discussed during this hybrid meeting are described below.

Operating Experience Related to Safety and Relief Valve Failures The NRC staff provided a presentation summarizing the failure of a pressurizer safety valve at Farley Unit 2. Through its review, the NRC staff has learned that safety and relief valve leakage can cause steam cutting of internal parts that might result in safety and relief valves lifting outside their acceptance band or failing to lift. The NRC staff will continue monitoring operating experience for this failure mechanism of safety and relief valves with follow-up action as appropriate.

Presentation - Safety/Relief Valve Failure Mechanism - ML24080A099 Evaluation and Proposed Recommendations on Centralized Inspections The NRC staff provided an update on their evaluation of inspecting centralized licensee functions as part of baseline inspections. The staff discussed industry input from the December 15, 2023, public meeting (Meeting Summary ML24004A161) and shared some of the technical staffs evaluation and recommendations awaiting final alignment from NRC senior management.

CONTACT: David M. Aird, NRR/DRO 3012870725

Representatives from NEI provided a short follow-on presentation on the topic with several industry recommendations.

Both NRC staff and industry aligned on the recommendation to capture considerations for future inspection development and revisions to consider centralized industry functions and agreed on a near-term public workshop to discuss more specifics on the NRCs evaluation and industry positions. That public workshop will be scheduled in April or May 2024.

Presentation - ROP Bi-Monthly Update To Discuss Centralized Inspections - ML24074A470 NEI Presentation - Inspections of Centralized Programs - ML24088A225 Digital Instrumentation and Controls Operating Experience Smart Sample The NRC staff announced that a new Operating Experience Smart Sample (OpESS) was published on February 12, 2024 (ML23235A248) on digital instrumentation and controls.

All OpESSs are available on the NRC public website:

https://www.nrc.gov/reactors/operating/ops-experience/operating-experience-smart-sample.html NUREG 1022 Reporting Guidance Supplement 2 Update The NRC staff presented background information, schedule, and proposed significant changes to a draft Supplement 2 to NUREG 1022 Revision 3, "Event Reporting Guidelines: 10 CFR 50.72 and 50.73. The draft Supplement 2 should be issued for public comment in April 2024.

The NRC encourages electronic comment submission through the Federal rulemaking website:

Presentation - Degraded and Unanalyzed Condition Reporting Guidance Supplement 2 Update

- ML24081A148 Licensee Revision to NRC Performance Indicator FAQ 23-03 NextEra staff previously introduced a draft frequently asked question (FAQ) related to a site-specific exemption for IE01, Unplanned Scrams per 7000 hours0.081 days <br />1.944 hours <br />0.0116 weeks <br />0.00266 months <br /> (ML23318A178). Turkey Point Unit 3 experienced a scram on September 22, 2023, caused by a lightning strike and grid disturbance. The NRC staff accepted this as FAQ 23-03 for review at the ROP public meeting on November 16, 2023.

At the January 17, 2024, ROP public meeting, the NRC presented a proposed response of not granting an exemption from IE01, Unplanned Scrams per 7,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> for the event on September 22, 2023. Subsequently, NextEra staff withdrew the FAQ, then elected to revise the original FAQ submittal, and presented those changes at this public meeting. Consistent with the performance indicator FAQ process, the NRC will review the revised submittal and propose a response at an upcoming public meeting.

Revised FAQ 23 ML24081A161 Other Items / Open Discussion The NRC staff discussed external stakeholder interest (first indicated during the Regulatory Information Conference [RIC]) in providing input into the NRCs selection of the next series of

Focused Engineering Inspections (FEIs). The NRC staff indicated an openness to considering industry input on future FEI topics. The NRC staff indicated that they would share some of their potential FEI topics with the industry at the next ROP public meeting in May and appreciate any follow-on discussion with industry by the ROP public meeting in July to stay on track for FEI selection, development, and implementation for the next engineering inspection cycle.

The Next ROP Meeting The next ROP bimonthly public meeting is tentatively scheduled for May 15, 2024.

Communicating with the NRC Staff At the start of all ROP public meetings, the project manager provides contact information for the public to use to provide their name and affiliation as a participant in the meeting. This contact information is also provided for submitting questions and comments to the NRC technical staff.

Please note that any questions and/or comments pertaining to the ROP can be sent to David.Aird@nrc.gov and will be forwarded to the appropriate NRC staff. The Contact Us about ROP page on the ROP public website can also be used to submit questions and comments regarding the ROP (https://www.nrc.gov/reactors/operating/oversight/contactus.html).

Conclusion At the end of the meeting, NRC and industry management gave closing remarks. The industry representatives expressed appreciation for the open dialogue and willingness of NRC staff to hear industry views. The NRC management stressed the importance of the NRC being focused on providing reasonable assurance of public health and safety when considering changes to the ROP.
