T9 Probabilistic Flood Hazard Assessments for Nuclear Facilities

During this session, panelists will discuss probabilistic flood hazard assessments (PFHA) strategies and methods for use in probabilistic risk assessments (PRAs).  Panelists will identify and solicit presentations on the state-of-the-science in extreme flood assessments within a risk context.  Flood assessments include combinations of flood-causing mechanisms associated with dam safety, riverine floods, local intense precipitation, hurricane storm surge, tsunami, and others.  The session will encourage sharing of information to bridge the current state of knowledge between extreme flood assessments and risk assessments of critical infrastructures (systems, structures, and components (SSCs)).  Ideas and insights on possible methods to potentially apply PFHA within the risk-informed licensing and oversight realm of nuclear reactors also will be discussed.  Presentations will build on the accomplishments of the PFHA Workshop being held at the NRC auditorium, January 29–31, 2013.  Federal agency, industry, and academic experts involved in flood hazard assessments of extreme hydrometeorological events will be contacted to share their knowledge and insights.
