1 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Grant # 31310021M0007 Grantee: University of Maryland Title of Grant: Application of Advanced and Hybrid Risk Tools in External Hazard PRA:
Challenges and Opportunities Period of Performance: 11/30/2020-11/29/2023 (FY2020 Notice of Funding Opportunity NOFO)
Executive Summary This research project will identify and assess the potential of the latest probabilistic risk assessment (PRA) technologies to inform and support NRCs transformation into a modern, risk-informed regulator. These technologies will be assessed from the perspective of external hazard PRA and their potential to: (1) support and inform NRCs risk-informed regulatory processes and transformation efforts, (2) address technical gaps, uncertainties, and limitations in current technologies supporting risk-informed decision-making (RIDM), and (3) offer opportunities to leverage more advanced technologies to bolster technical bases or improve efficiency in RIDM.
Projects activities include a survey and assessment of novel PRA tools, exploration of opportunities to develop hybrid PRA tools that merge existing and new PRA technologies, identify potential impacts of new tools on RIDM and regulatory processes, and synthesize knowledge to summarize challenges & opportunities in the use of modern and hybrid PRA tools. Using external hazard PRA as a research boundary object, this project will identify how modern PRA tools can expand risk assessment capabilities and support more robust and effective RIDM while continuing to leverage extensive investments in existing PRA technologies.
