Dmitry Grishchenko

Dmitry Grishchenko is a Researcher at the Royal Institute of Technology (KTH) within the Department of Nuclear Science and Engineering. His work focuses on advanced thermal-hydraulic modeling, severe accident analysis in nuclear reactors, and multiphase flow dynamics. He contributes to teaching courses such as Numerical Methods in Nuclear Engineering (SH2774) as a course coordinator and Reactor Physics (SH2600) as an assistant.
His research revolves around critical nuclear safety topics, including steam explosion phenomena, thermal stratification in pressure suppression pools, and computational fluid dynamics (CFD) validation for nuclear systems. He leads experimental and numerical studies on steam injection dynamics, sparger design, and risk assessment for Nordic BWRs. Collaborations include projects like McSAFER and SAFEST, addressing safety challenges in small modular reactors and severe accident management.
Publications span over a decade, emphasizing innovative CFD techniques, code validation (e.g., TEXAS-V, Star-CCM+), and experimental facilities like PANDA and SEFACE. His work bridges fundamental fluid dynamics with applied nuclear engineering, contributing to safer reactor designs and accident mitigation strategies.
