SUMMARY

OF OCTOBER 26, 2023, PUBLIC MEETING WITH THE BOILING WATER REACTOR OWNERS GROUP EXECUTIVE OVERSIGHT COMMITTEE AND THE NUCLEAR REGULATORY COMMISSION

On October 26, 2023, the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Reactor Regulation (NRR), management met with representatives of the Boiling Water Reactor (BWR) Owners Group (BWROG) Executive Oversight Committee (EOC) in a virtual public meeting. The purpose of the meeting was for the NRC and BWROG managers to discuss current BWR issues of interest. At the meeting, both the NRC staff and the BWROG representatives made presentations. The meeting notice is available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML23268A433, and presentation slides can be viewed in ADAMS at Package Accession No. ML23349A203. A list of attendees is enclosed.

The BWROG representatives presented the following topics:

BWROG Introduction

In the introduction, the BWROG representative provided an overview of the BWROG, including its mission, organizational structure, leadership, committees (Special topic, System improvement, Plant performance, Core), membership, and priorities. The BWROG EOC priorities include:

Plant/equipment reliability associated with obsolescence, project management optimization, surveillance test intervals, and best practices.

Risk initiatives associated with risk informed completion times, outage safety assessment, peer reviews, optimizing probab ilistic risk assessment (PRA) models, Title 10 of the Code of Federal Regulations (10 CFR) 50.69, Risk-Informed Categorization and Treatment of Structures, Systems, and Components, implementation.

Knowledge transfer in the areas of handbooks, workshops/training, workforce proficiency, and troubleshooting guides.

International support and participation.

TSTF-576 Update

For the TSTF-576, Revise Safety/Relief Valve Requirements, the BWROG representative discussed that the valve issue will have the intended impact and that there was success on this issue within the last year because of interactions with the NRC and the industry.

Licensing and TSTF-585

For TSTF-585, the BWROG representative discussed that the TSTF provides an alternative 24-hour completion time to initiate shutdown on entering limiting conditions for operation (LCO) 3.0.3. Regarding the NRC suggested revisions, the BWROG plan to send back to the NRC by the end of 2023.

The BWROG also provided an update on other major TSTF activities which include, TSTF-592, Rev. 0, Revise Automatic Depressurization System (ADS) Instrumentation Requirements, TSTF-597, Rev. 0, Eliminate LCO 3.0.3 Mode 2 Requirement, and TSTF-596, Rev. 0, Expand the Applicability of the Surveillance Frequency Control Program (SFCP).

Regarding strategic initiatives, the BWROG representative discussed plans for 10 CFR 50.36 Rulemaking, treatment of TS as data rather than as a document, and work with Nuclear Energy Institute (NEI) on the license amendment review process. The BWROG representative also indicated that a project was started to revise the Informed Completion Time (RICT) program to extend the 30-day backstop to 90 days. The NRC representative also clarified that feedback regarding strategic initiatives will be through the TSTF.

Risk (Software Common Cause, PRA Configur ation Control Inspections, Code Case N-752)

For the treatment of common cause failure (CCF) in digital instrumentation and control systems, the BWROG representative indicated that the industry is outpacing the updates of NRC policy and guidance and were pursuing guidance regarding digital CCF modeling. The NRC staff were able to clarify their questions about regulatory gaps the industry sees, associated with current regulatory infrastructure, risk informing CCF, and 10 CFR 50.59, Changes, Tests, and Experiments, options. The industrys concern wa s related to change in NRC staff personnel in the digital CCF review area and not an issue regarding the regulatory infrastructure and current guidance.

For PRA configuration control inspections, the BWROG representative discussed a Self-Assessment Checklist as part of the PRA Configuration Control process, and that the PRA Inspection procedure/guidance be made available to licensees. The BWROG representative indicated that they would like feedback on the inspection approach. The NRC representatives indicated that there was ve ry high NRC regional engagement. The NRC regions have the lead and NRC headquarters staff will assist. The NRC staff representative also discussed PRA oversight including smart sample guidance, and cross regional inspection panels for consistency.

For the Code Case N-752, the BWROG representatives indicated that they see an issue with alignment regarding previous submittals and wanted to see the NRC maintain alignment in reviews. The NRC representative indicated that plant specific reviews are in-house, and the NRC have held recent public meetings on this issue.

Power Uprates

For power uprates, the BWROG representative indicated that there is potential for power uprates in BWRs and that likely candidates will come from the Idaho National Laboratory report 23-74681, Assessing the Impact of the Inflation Reduction Act on Nuclear Plant Power Uprate and Hydrogen Cogeneration. Additionally, utilities who have not submitted subsequent license renewal (SLR) could be candidates in the 2025 - 2026 window. There were also discussions about preparing the licensing process for future submittals. The NRC representatives also mentioned that lessons learned from past integr ated review team reviews could be used as an example for power uprate submittals.

The NRC staff presented the following topics:

NRC introduction, opening, and closing remarks.

- Mike King - Deputy Office Director for Reactor Programs

Small Modular Reactor

- Michelle Hayes, Division of New and Renewed Licenses (DNRL), Office of Nuclear Reactor Regulation (NRR)

Human Factors Engineering

- Jesse Seymour, Division of Reactor Oversight (DRO), NRR

Subsequent License Renewal

- Lauren Gibson, DNRL, NRR

- John Moses, Division of Rulemaking, Environmental, and Financial Support, Office of Nuclear Material Safety and Safeguards G. George

Data-driven Licensing

- Doug Broaddus, Division of Operating Reactor Licensing, NRR

NRC Introduction

Mike King, Deputy Office Director for Reactor Programs, NRC, provided opening and closing remarks, and thanked the BWROG EOC for the opportunity to discuss topics of mutual interest as they pertain to the BWR fleet, including licensing, risk related topics, power uprates, small modular reactors, human factors engineering, and SLR. In addition, provided responses to the BWROG questions on NRC licensing and oversight.

Small Modular Reactor

For the small modular reactor presentation, the NRC staff provided an update on NRCs cooperation with the Canadian Nuclear Safety Commission (CNSC). The focus was on the 2022 charter that established cooperation on GE Hitachis BWRX-300 small modular reactor and the discussion included areas of collaboration, challenges, and next steps. Collaborations under the 2019 memorandum of cooperation on advanced reactor and small modular reactor technologies were also shared.

Human Factors Engineering

For the human factors engineering update, the NRC representative discussed how human factor engineering (HFE) supports operator performance, some benefits of digital upgrades, variations in plant-specific HFE-related regulatory basis, and commitments and need for early engagement regarding digital upgrades.

Subsequent License Renewal

For the SLR, the NRC staff discussed possible ways to make SLR more efficient, initial license renewals under review, provided an update on the SLR application status, planned environmental reviews and timelines, and outlook by the end of 2024. For the outlook, the NRC staff highlighted that 9 applications are expected by end 2024, resources are expected to be a potential challenge, and that the industry should continue to send Notices of Intent so that the NRC staff can plan for future submittals.

Data-driven Licensing

For the data-driven licensing discussion, the NRC staff focused on the managing licensing workload, licensing actions, performance drivers, resource estimating, tracking performance, and using data to drive improvements. The NRC staff also addressed questing from the BWROG representatives, on how past practices, historical data, help best practices, and whether different parts of the NRC organization were more efficient. The NRC staff explained that to be more efficient, we must make the routine work easier and more efficient.

No comments or questions were received by members of the public.
