Emilian L Popov

Senior Research Staff

Dr Emilian Popov is a Senior R&D staff member for the Thermal Hydraulics group in the Nuclear Energy and Fuel Cycle Division at Oak Ridge National Laboratory (ORNL). Dr Popov received his PhD (1998) in nuclear engineering from the Sofia Technical University, Sofia, and his BS and MS (1988) in thermal physics from the Moscow Power Institute, Moscow. He has over 25 years of experience in nuclear thermal design and safety analyses, computational fluid dynamics, single and two-phase turbulent flows and heat transfer, advanced multi-physics modeling, analytical benchmarks and parallel scientific software development. At ORNL, he works on the development of advanced multi-physics design and safety basis models for the present highly enriched uranium core and the low-enriched uranium core designs of the High Flux Isotope Reactor (HFIR). Dr Popov is an internationally recognized expert with a proven record for success. He collaborated with leading nuclear vendors (Westinghouse, Siemens, Framatome) and trained at world leading research institutions like Cadarache center in France. He also serves as a reactor technology consultant to the DOS and contributes to promote the US advanced reactors deployment worldwide. Dr Popov is a recipient of the UT-Battelle’s 2019 Mission Support Award for his contributions towards the HFIR event causal analysis.
