In addition, John Hughey, NRC Reliability and Risk Analyst, discussed the NRC experience with oversight of 50.69 implementation. The final presentation on 50.69 safety benefits was delivered by Suzanne Loyd, Constellation Senior Manager, and Henri Lee, Southern Company Procurement Engineering Lead.

Laura Dudes, NRC Acting Office Director of NRR, delivered opening remarks emphasizing the importance of workshops in facilitating the exchange of experiences and best practices, particularly in the licensing and oversight of the 10 CFR 50.69 process. It was explained that as implementation progresses, valuable lessons continue to emerge, particularly in inspection and regulatory oversight. It was also shared that a key challenge in any initiative is ensuring mutual

understanding, making clarity and open discussions essential. Over the past seven years, substantial progress has been made, with 70 percent of the fleet now approved under this framework, enhancing reactor safety. Sustaining this momentum requires refining oversight and applying lessons learned to future risk-informed initiatives. The collaboration between NEI, the PWR and BWR Owners Groups, and NRC staff was crucial in developing the workshops meeting agenda. Special recognition was given to key leaders, including Meena Khanna, NRC Acting Director for the Division of Risk Assessment, for outstanding leadership, Robert Pascarelli, NRC Chief of the Probabilistic Risk Assessment Branch in NRR along with numerous contributors from industry and NRC staff, whose efforts have been vital in advancing communication and coordination in risk-informed decision-making. Attendees at the 50.69 workshop were also encouraged to participate in the March 6, 2025, NRC public meeting on Electric Power Research Institutes (EPRI) enhanced risk-informed categorization methodology for pressure boundary components.

Overview of 50.69 Process (NRC)

During this presentation, it was explained that 50.69 introduces a risk-informed categorization process for SSCs, expanding traditional classifications into four risk-based categories (RISC-1 through RISC-4). While RISC-1 and RISC-4 largely retain pre-50.69 quality treatments, RISC-2 and RISC-3 allow adjusted alternative treatment requirements. The process begins with identifying safety-significant functions, incorporating risk assessments such as PRA, and finalizing categorizations through an Integrated Decision-Making Panel (IDP). It allows alternative treatment requirements for some SSCs while imposing additional requirements on others. Safety-related SSCs classified as low safety significant (RISC-3) may see reduced regulatory burdens, whereas non-safety-related SSCs deemed safety significant (RISC-2) may require added treatments. However, key performance-based requirements like inspection, testing, and corrective actions remain. Periodic reviews every two refueling outages verify categorization validity, with immediate reassessments required for significant operational events. RISC-1 and RISC-2 SSCs retain regulatory required performance monitoring, while RISC-3 SSCs are allowed to implement alternative inspections and testing. The rule also allows implementation of alternatives to specific special treatment requirements (STRs) for RISC-3 and RISC-4, including 10 CFR Part 21 reporting, environmental qualification of electrical equipment, and the requirements of 10 CFR 50.65, except for risk assessment and management for maintenance remains. Alternative treatments to the requirements of Appendix B to 10 CFR Part 50 may also be implemented for RISC-3 and RISC-4 SSCs.

Development of 50.69 License Amendment Request (Industry)

During this presentation, it was explained that the 50.69 process is a risk-informed regulation aimed at categorizing and managing safety-related SSCs in nuclear power plants based on their safety significance. By focusing resources on more critical components, plants can reduce unnecessary regulatory burdens, such as costly Appendix B requirements, leading to significant operational cost savings while maintaining safety. The rule requires plants to demonstrate the adequacy of their PRA methods, addressing risks like internal and external hazards, fire, and seismic events. The approach is part of an ongoing effort to improve efficiency and consistency in safety programs. To date, 50.69 has been adopted by about 70 percent of U.S. plants, though the adoption rate and implementation strategies vary, with some plants moving faster than others. Industry initiatives like "Delivering the Nuclear Promise" have been key in promoting rulemaking improvements for increased safety and reliability. Duke Energy and DC Cook's experiences with 50.69 have highlighted challenges in categorizing components using PRA, such as handling uncertainties and assumptions, and the importance of clear communication

and collaboration between engineering, operations, and PRA teams. Industry groups have contributed valuable insights, improving the LAR process and audit efficiency, with lessons learned shared across the industry. The rule implementation has driven cultural and operational changes, emphasizing risk-based decision-making, better maintenance schedules, and enhanced operational efficiency. Moving forward, stakeholders continue to explore ways to refine the process further, including improving reviewer consistency and integrating 50.69 into broader risk-informed practices.

NRC Experience Reviewing 50.69 LAR Submittals (NRC)

During the workshop, it was explained that NRCs license application review process for 50.69 centers on evaluating the adequacy of the PRA, ensuring compliance with regulatory guidelines such as Regulatory Guides 1.200 and 1.201. The review emphasizes assessing the PRAs technical acceptability, including the closure of peer review findings, addressing unresolved issues, and evaluating sources of uncertainty that may affect safety system categorization. The key to the process is the integration of Diverse and Flexible Coping Strategies (FLEX) equipment in PRA models, ensuring its appropriate crediting and integration into risk-informed applications, with updated guidance for its use. The NRC is also considering alternative methods, such as the tiered EPRI seismic approach, which categorizes plants based on seismic risk and has been increasingly used in plant evaluations. Administrative best practices play a crucial role, including the adherence to NRC safety evaluation templates and the streamlined audit process. The shift to virtual audits has improved efficiency, allowing for more detailed review, flexible scheduling, and reduced travel costs while maintaining transparency. The process also encourages licensees to supplement their applications with additional information, ensuring the timely closure of knowledge gaps and minimizing the need for repeated requests for information. Lastly, the NRC is reviewing various methods and guidance for future updates, reflecting ongoing industry feedback and experience.

Industry Experience with 50.69 Implementation (Industry)

During this presentation, the discussion primarily centered on the regulatory frameworks and industry perspectives concerning NRC regulations, especially 50.69, and its impact on treatment alternatives for components. The session addressed several key issues, including risk categorizations, operability determinations, and the scope of license commitments. One of the main points was that while 50.69 allows for alternative treatments, the regulation does not grant exemptions. It was emphasized that components must retain their design function, even with alternative treatments, and the industry's approach to operability issues remains an ongoing topic of discussion. Additionally, it was emphasized that adjustments within 50.69 do not override license renewal obligations, ensuring the continued management of aging components.

Risk-based adjustments, such as the designation of RISC-3 SSCs, influence how 50.69 applies to design changes, offering flexibility while still maintaining compliance. The session highlighted the ongoing dialogue between the NRC and industry regarding the consistent application of risk-informed processes and the importance of ensuring clear regulatory compliance. The session concluded with a recognition of the complexity of the topics discussed and the need for continued engagement.

NRC Experience with Oversight of 50.69 Implementation (NRC)

This presentation focused on the implementation of oversight within NRC's regulatory framework, particularly highlighting experiences with 50.69 inspections. It provided an overview of key inspection procedures, baseline integration, and the insights derived from previous

inspections. The initial inspection procedure, IP-37060, is conducted when a plant has categorized enough systems for a risk-informed review. This inspection evaluates how well the program aligns with the regulatory framework, adherence to the categorization process, problem identification and resolution, as well as feedback and adjustments to processes. Baseline inspections, which incorporate 50.69 guidance, cover various areas such as maintenance effectiveness, plant modifications, valve inspections, commercial-grade dedication, and testing of risk-important equipment. Additionally, a PRA configuration control smart sample has been performed six times to ensure that plants maintain valid risk assessment models. Since 2016, six plants have undergone implementation inspections. Half of these plants had no inspection findings, while the other half had minor, low-safety-significance findings, mainly concerning improper categorization and incomplete risk reviews. Baseline inspections between 2023 and 2024 identified three green (very low safety significant) findings related to alternative treatment issues. The key takeaway from the discussion was that no widespread problems were detected in the implementation of 50.69, though observations highlighted areas where risk categorization and alternative treatment tracking could be improved. The importance of feedback mechanisms to evaluate system failures and apply appropriate alternative treatments was also emphasized.

The session stressed the need for continuous learning and sharing of inspection insights rather than suggesting systemic failures in the implementation process.

During the workshop, panel members responded to as many questions as possible within the agendas specific allotted timeframe for each presentation. One follow-up response to an inquiry on oversight of non-Appendix B vendors included the following. The NRC-approved process implementing NRC regulation allows alternative treatment in lieu of Appendix B requirements.

Vendor requirements will be determined on a case-by-case basis by the licensee based on the alternative treatment established by licensee for a RISC-3 SSC. NRC does not approve alternative treatments; however, alternative treatments are inspected under the reactor oversight process (ROP) in several baseline inspection procedures.

50.69 Safety Benefits (Industry)

This presentation highlighted the complexity and importance of implementing 50.69, emphasizing its role in prioritizing safety and reliability. The discussion reinforced that 50.69 is not intended to reduce work but to focus resources on risk-significant components while offering flexibility in managing lower-risk components. It was stressed that the program enables better allocation of resources, thereby enhancing overall plant safety and efficiency. By allowing for alternative treatments, 50.69 facilitates faster restoration of degraded components and helps resolve issues related to obsolescence. There was clarification that, while cost savings are a noted benefit, they should not be equated with reduced safety, as risk-informed processes have historically improved both safety and efficiency. The programs significance was underscored by the substantial investment of time and resources from both industry professionals and regulatory bodies. A real-world example from Limerick Generating Station demonstrated how 50.69 successfully addressed critical service water piping issues, preventing costly shutdowns and ensuring continued plant operation. Ultimately, the overarching message was that risk-informed processes, including 50.69, enhance both safety and performance, aligning industry efforts with regulatory expectations.

In the closing remarks, appreciation was given to the presenters, panelists, and organizers for their efforts in making the workshop a success, with an estimated 300-400 participants. The discussion reaffirmed the commitment to regulatory consistency and highlighted the focus on expanding risk-informed decision-making in future sessions. A post-workshop survey will gather feedback for improvement, and logistical reminders were provided for attendees. Overall, the

workshop was recognized as a valuable platform for knowledge transfer and engagement between NRC staff and industry representatives.
