NE Seminar: “Multiphysics Nuclear Engineering: The Nexus of Reactor Neutronics, Thermal Hydraulics, and Nuclear Materials to Transform Nuclear Reactor Design and Nuclear Fuel Safety”

1:55 pm - 2:55 pm

Rhines Hall 125



The research portfolio of my group lies at the intersection of nuclear thermal hydraulics, reactor neutronics, and nuclear materials. This includes analysis of nominal nuclear reactor operation, anticipated transients, and accident events. My group is a key contributor in the study of reactor performance and safety characteristics of Accident Tolerant Fuel (ATF), including fuel safety research and transients, as well as advanced reactor concepts. Accelerating the deployment and extending the availability of ultra-low carbon-emitting existing technology (including safety improvements or life extensions for existing nuclear power plants) are also vital pillars of our research. This talk articulates my vision for my research group. I also highlight recent progress in: advanced manufactured materials to enhance reactor and fuel safety, improved mechanistic modeling of critical heat flux to better understand reactor safety margins, and advanced composite moderators to make high-temperature reactors more economical. I will also highlight my teaching, service to the university and profession, and actions taken to help create an inclusive environment.
