NUC E Seminar Series: Thermal Hydraulics for Materials: Integrated Approach for Advanced Nuclear Fuel and Reactor System Studies

Abstract

In this seminar, an overview of key technical challenges to nuclear fuel and reactor safety research that calls for integrated insights is presented. Next, an in-depth discussion on the development of ultra-thermal shock tolerant material by controlling surface heat transfer, investigation of boiling-induced stresses, and advanced instrumentation for pebble heat transfer be discussed, to demonstrate the importance of integrated approach in mechanistic understanding of nuclear fuel behavior in extreme environments.

Biography

Youho Lee joined the University of New Mexico (UNM) in September 2016 as an assistant professor in the nuclear engineering department. Dr. Lee is a nuclear engineer studying various solid-fluid interface phenomena in extreme environments and their influence on the mechanical behavior of nuclear materials. This approach combines experiments, modeling, and system-level computations. His research interests include thermal hydraulics-mechanics coupled study for the mechanistic understanding of key design basis accidents, development of ultra-thermal shock tolerant material, flow-accelerated corrosion, accident tolerant nuclear fuel development, and reactor safety. Dr. Lee received a B.S from the Korea Advanced Institute of Science and Technology (KAIST) in 2009. He earned an M.S and Ph.D., both in nuclear engineering, from the Massachusetts Institute of Technology in 2011 and 2013, respectively. Prior to joining UNM, he was a researcher at KAIST. He is a recipient of the Korean government scholarship for overseas studies. He was awarded the best paper in the division of fuel and materials at the 2014 Korean Nuclear Society Conference.
