Panel Session: Emerging PSA Needs with respect to Advanced Reactor Technologies Kevin Coyne US Nuclear Regulatory Commission Kevin.Coyne@nrc.gov
Motivation
- New and advanced designs are expected to include simplified high-reliability safety systems with reduced reliance on operator actions
- Limited experience in performing probabilistic safety assessment (PSA) and management activities for new and advanced reactor designs
- New fuel designs and coolants may necessitate new analysis methods
- Risk metrics, mission time considerations, accident sequence identification, and end-state definitions
- New safety considerations, such as siting in or near populated areas or in locations exposed to more diverse hazards; transportation of fueled modules; remote or autonomous operations; and multi-module and multi-unit risk.
- Increased reliance on passive safety features
Some potential Challenges
- How do we best use PSA technology to ensure nuclear plant safety while supporting efficient licensing and certification reviews?
- Do we need new PSA analysis and modeling techniques to address new concepts of operation (e.g., remote or autonomous operation)?
- Do new siting considerations or the use of reactors for process heat generation impact PSA modeling needs?
- Preparing the next-generation workforce?
- Use of PSA methods beyond traditional event tree/fault tree methods?
- Ensuring an adequate level of PSA technical acceptability and quality with a limited number of experts able to perform peer review activities?
- How can PSA techniques support the design and pre-operational phase?
