US NUCLEAR REGULATORY COMMISSION Human Factors Engineering:

Application to Existing Plants / Digital Upgrades Jesse Seymour Office of Nuclear Reactor Regulation October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 12

HFE Application & Digital Upgrades October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC

  • Human Factors Engineering (HFE) supports operator performance and is a key design consideration o

Digital upgrades can reduce operator workload and reliance upon manual actions

  • Plants vary in their HFE-related regulatory bases and commitments o

Both the NRC staff and the facility licensee need to understand the licensee's HFE commitments and licensing basis

  • Timing of integrated system validation (ISV) completion can present challenges (e.g., ISV results not being available in time to support a submittal) o Tools such as early pre-application engagement and methods such as multi-stage validation (MSV) can help to navigate this 13 13

HFE Application & Digital Upgrades October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC

  • Licensees are increasing the scope of digital upgrades to main control room
  • It is important to engage the NRC staff early to establish a common understanding of regulatory bases, project scope, and timelines for HFE-related design and validation activities
  • NRC staff note that awareness of MSV (including how it can be used as an effective component of broader HFE design and validation processes) can be improved.

14 14

Possible Ways to Make Subsequent License Renewals More Efficient October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 18

  • Things NRC has already implemented o

Tiger team for acceptance review rather than all reviewers o

Eliminating the keyword list and report for Operating Experience Reviews o

Smaller scoping and screening audit o

One Advisory Committee on Reactor Safeguards (ACRS) meeting o

Inspections not part of licensing decision

Possible Ways to Make Subsequent License Renewals More Efficient October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 19

  • Things we are currently working on o Streamlining Safety Evaluation o Streamlining audit report o Modernizing the internal Technical Review Package (TRP) tool o Revising generic documents (SRP-SLR, GALL-SLR, GEIS)
  • Things we are discussing to improve efficiencies o Reconsidering Peer reviews o Reconsidering audit execution and time available
  • Open to suggestions

Possible Ways to Make Subsequent License Renewals More Efficient October 26, 2023 US NRC - PUBLIC MEETING WITH BWROG 20 Things Industry could do to help make the NRC review more efficient o

Keep the GALL numbering in your application o

Review previous Audit Reports and Breakout questions o

Proactively communicate Late Breaking Operating Experiences o

Early communication of complex issues o

Early communication on Annual updates, especially if changes are expected o

Maintain a master copy of the application with all the changes What would be the implications of submitting this to NRC? (e.g., cost from applicants, NRC efforts to confirm the information, etc.)

Could NEI maintain the clean copies for future applications benefitsfor future applications benefits

Managing the Licensing Workload October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 31

  • Historically, managing and tracking the status of ~1000 licensing reviews each year has been a time-consuming manual process that was more reactive than proactive.
  • NRC has increased access to licensing data, and using modern data visualization tools has established a more effective and consistent processes for managing our licensing work.
  • NRC is using an integrated workload management process to inform changes to our licensing processes and performance goals.

Licensing Actions Managed FY2018 to FY2023 October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 32 Amendments by Type Amendments by TSTF

Performance Drivers October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 33

  • Historically, NRRs performance metric has been to complete 90% of the reviews within 1-year.
  • NRR has shifted its focus to developing resource and schedule estimates that reflect the historical performance of the various types of completed reviews.
  • NRR is utilizing its licensing data to:

o inform the development of estimates communicated to applicants o

track in real-time our performance against those estimates, and o

complete our reviews within 75% - 115% of the estimated schedule and less than 125% of the estimated resources

Using Data to Drive Improvements October 26, 2023 U.S. NRC - PUBLIC MEETING WITH BWROG EOC 38

  • The NRC staff is using historical performance data to inform the schedule and resource estimates for licensing reviews and identifying specific types of reviews that have taken significantly more or less than 1 year.
  • NRRs is using real time data to gauge performance against its estimated completion schedules (ECS) to drive schedule accuracy to 75% < ECS < 115% and identify areas for improvement.
  • NRR is utilizing its data to identify and proactively mitigate potential future challenges.
