©2023 Nuclear Energy Institute 2 Meet the Moment.
Drivers Forecast Right-sizing Reviews Feedback Next Steps The Renewals are coming.
Lets discuss.
Were ready to do our part.
Where do we go from here?
Agenda
©2023 Nuclear Energy Institute 3 U.S. National Climate Task Force Goals Reducing U.S. greenhouse gas emissions 50-52% below 2005 levels in 2030 Reaching 100% carbon pollution-free electricity by 2035 Achieving a net-zero emissions economy by 2050
©2023 Nuclear Energy Institute 4 According to McKinseys Global Energy Perspective 2022 Study, global electricity demand is expected to triple by 2050 across a range of scenarios.
Transportation (electric vehicles)
Building operations (electrified heating)
Industrial processes (low-carbon steelmaking)
Electricity Demand Rising
©2023 Nuclear Energy Institute 5 Nuclear energy today provides ~20% of all electricity in the U.S. with no carbon emissions Nuclear is the largest source of clean energy in America at nearly 55%
Energy independence and security is of paramount importance We must continue operation of existing nuclear reactors across the country to meet this moment The Operating Fleet

©2023 Nuclear Energy Institute 8 Reexamine what is needed for reasonable assurance Strong leadership and staff discipline is essential Adopt a more graded approach for reviews Schedule and resource metrics must strive for excellence and predictability Right-sizing SLR Reviews
©2023 Nuclear Energy Institute 9 Plants are highly reliable and operating at record levels Minimal significant operating experience has emerged during extended operation Corrective Action Programs have matured significantly since ILR Reasonable Assurance
©2023 Nuclear Energy Institute 10 Nuclear Reliability: Non-Fossil Electricity Sources
©2023 Nuclear Energy Institute 11 In the Spring 2023 refueling outage season, 32 units came offline to refuel 14 of these units had performed breaker-to-breaker runs Of the 14 units, 10 have approved 60-yr licenses and 2 have approved 80-yr licenses Nuclear Performance - Operational Excellence
©2023 Nuclear Energy Institute 12 Reinforce review guardrails Expended resources need a commensurate connection to risk/safety significance Management focus earlier in the review process on technical concerns Improve timeliness of deliberation and decision-making Matrixing reviewers has impacted efficiency and introduces competing priorities Leadership and Staff Discipline
©2023 Nuclear Energy Institute 13 Risk and safety significance should be a driver for depth of review Maximize credit for adherence to guidance and standardization Focus on what has changed since the ILR review AMPs that are unchanged over GALL revisions AMPs with minimal changes over GALL revisions Fleetwide programs already reviewed for another ILR/SLR Licensee commitments that continue from ILR through SLR Routinely inspected programs subject to other regulatory requirements ISI, IWE, IWL, FAC, Fire Protection, App. J, Boric Acid Control Graded Approach
©2023 Nuclear Energy Institute 14 Data analytics What review areas are consuming the most resources?
Is there commensurate safety significance?
Additional granularity and visibility in schedule (mid-term milestones)
Combine or eliminate audits Portal configuration best practices Standardized formats Credit inspection reports for ILR, PI&R, ARD Reevaluate review areas with significant margin or no identified impacts (e.g., Env.
Assisted Fatigue)
More Investigation
©2023 Nuclear Energy Institute 15 Continue to maximize the use of RCIs Standardize audit format and terminology Strive to exceed the 14-day specified lead time in LIC-111 for audit documents, discussion topics, and special requests 3-4 weeks in advance will yield best results Environmental Review Observations
Feedback and Discussion
©2023 Nuclear Energy Institute 17 Evaluate exchanged information Examine data to develop target list Prioritize recommendations with maximum benefits Establish recurring cadence to discuss progress Next Steps
