This is a past event.

 “Liquid-Metal and Two-Phase Flows in Advanced Nuclear Engineering Systems”

ABSTRACT:

Nuclear science and technology benefit human society in many ways.  About 20% of the electricity generated in the United States is from nuclear energy.  Advanced nuclear reactors or Generation IV reactors are crucial in combating climate change while keeping up with the energy demand in the future.  On the other hand, medical isotopes, generated from nuclear systems, are widely used in disease diagnostic procedures and cancer treatments.  Mo-99 is the most commonly used medical isotope, but the majority of Mo-99 supplied to the United States is provided by foreign producers using the proliferation-sensitive high-enriched uranium (HEU).  In this talk, recent research activities and findings in thermal-hydraulics to advance nuclear engineering applications will be presented, including (1) liquid-metal flow experiments and simulations for Generation IV reactor development and domestic medical isotope production (e.g., Mo-99, Ac-225) using low-enriched uranium (LEU), (2) gas-liquid two-phase flow experiments and modeling for Computational Fluid Dynamics (CFD) and reactor system codes benchmark and improvement, and (3) modeling of jet impingement in postulated pipe rupture to assist safety components design and evaluation.

BIOGRAPHY:

Dr. Ran Kong earned his Ph.D. degree in nuclear engineering from Purdue University in 2018, where he continued his postdoc training for three years.  His research interests include thermal-hydraulics experiments and simulations, liquid-metal flow, gas-liquid two-phase flow and instrumentation development, advanced reactor design, and reactor safety analysis.  His work establishes the technical basis for the design, licensing and operation of various nuclear engineering systems.    

Tuesday, February 22 at 11:00 a.m. to 12:00 p.m.
