Licensing Perspectives on Probabilistic Risk Assessment and Its Applications Small Modular Reactors and Advanced Non-Light Water Reactors American Nuclear Society International Topical Meeting on Probabilistic Safety Assessment and Analysis (PSA 2019)
Ian Jung Senior Reliability and Risk Analyst Advanced Reactor Technical Branch Division of Advanced Reactors Office of New Reactors
NRC is committed to risk-inform Further risk-inform the current regulatory framework in response to advances in science and technology, policy decisions, and other factors, including prioritizing efforts to focus on the most safety-significant issues.
NRC Strategic Plan (NUREG-1614, Volume 7) - Safety Strategy 2 2
Advanced non-LWRs present opportunities Licensing Modernization NRC Vision and Strategy Project (NEI 18-04)
Implementation Action Plans to develop technology-inclusive, risk-informed, and performance based Draft Regulatory Guide 1353 3
PRA acceptability plays a key role in risk-informed applications the ability of a PRA to support risk-informed regulatory decisionmaking is measured in terms of its appropriateness with respect to scope, conformance with the technical elements of a PRA, level of detail, and plant representation Source: ADAMS Accession No. ML18024A766 4
The following topics need increased attention
- Passive and inherent features
- Novel designs
- Key assumptions
- Non-traditional PRA methods
- Peer reviews
- Iterative process
- Level 3 5
NRC is modernizing licensing of advanced non-LWRs
- Division of Advanced Reactors formed
- Draft Regulatory Guide 1353 Core Team
- Technical readiness Policy
- Regulatory readiness Licensing
- Communication Technical 6
The staff is working on PRA-related activities
- Pre-application interactions with multiple designers
- Non-LWR PRA standard
- Lessons learned from NuScale small modular reactor review
- Review of the existing regulatory infrastructure
- Guidance development as necessary
- Policy matters to be identified early
- Training
- Staff guidance development
- Acceptance criteria/decision criteria 7
Summary
- The staff is working to establish a risk-informed and performance-based approach to regulatory advanced non-LWRs
- PRA is expected to play a key role in a risk-informed manner
- The staff and industry are working closely to modernize advanced non-LWR licensing 8
