Thermal Hydraulics for Material Mechanics: An Integrated Approach to Studying Nuclear Fuel and Reactor Safety

Youho Lee

Assistant Professor

Department of Nuclear Engineering

University of New Mexico

Mon, 02/05/2018 - 4:00pm to 5:00pm
3105 Etcheverry Hall
Spring 2018 Colloquium Series

In this seminar, an overview of the key technical challenges to nuclear fuel and reactor safety research that benefits from integrating thermal hydraulics and material mechanics will be presented. An in-depth discussion will ensue on the development of ultra-thermal shock tolerant material by controlling surface heat transfer, boiling-induced stresses, advanced instrumentation for pebble heat transfer, and machine-learning aided nuclear accident diagnosis; and the potential of this approach for creating new perspectives and solutions to modernizing nuclear reactor engineering.

About the Speaker: 

Dr. 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 by integrating thermal hydraulics and material mechanics. His research interests include thermal hydraulics-mechanics coupled studies on reactor safety, reactor thermal hydraulics, nuclear fuel mechanical modelling and design, and machine learning aided accident diagnosis. Dr. Lee received a B.S. from the Korea Advanced Institute of Science and Technology (KAIST) in 2009, and an M.S. and Ph.D. in nuclear engineering from the Massachusetts Institute of Technology (MIT) in 2011 and 2013, respectively. Prior to joining UNM, he served as a postdoctoral research fellow at KAIST. He was awarded the best paper in the division of fuel and materials at the 2014 Korean Nuclear Society Conference.
