Workshop on Flooding Risk Assessment: Validation, Application, and Experimental Studies

Moderators: Philippe Bardet and Bob Youngblood

Date: Tuesday August 6, 2019

Time: 10:15 a.m. - 5:15 p.m.

This workshop will feature several focused presentations related to recent Department of Energy (DOE) sponsored and Nuclear Regulatory Commission (NRC) sponsored research activities. Advanced computer simulation tools are increasingly being used to support risk-informed systems analysis (RISA), an integrated deterministic/probabilistic safety analysis methodology developed in DOE’s Light Water Reactor Sustainability (LWRS) program. NRC has also invested significant resources in probabilistic flood hazard assessment (PFHA) and PRA research. Recent research has seen new developments in PFHA, as well as validation methodology for safety analysis codes. The validation methodology builds upon the U.S. Nuclear Regulatory Commission’s Code Scaling, Applicability and Uncertainty (CSAU) methodology, also known as Evaluation Model Development and Assessment Process (EMDAP). This workshop comprises of state-of-the-art presentations in the area of regulatory research perspectives, capability of advanced simulation tools, methodology development, uncertainty quantification through application case studies, and experimental studies to support the development of data-driven methodology.
