Abstract: Next-gen small nuclear reactors or microreactors are gaining significant attention due to their utilization extending to civilian, military, and space applications. A few of the unique features that distinguish these reactors from current fleet of commercial power plant reactors is their use of high-assay low enriched uranium (HALEU) fuel, newer materials, and their compact size. These special purpose reactors are aiming to be flight-ready, transportable, and self-regulating to be used for both remote (solo) and hybrid sites in conjunction with renewables. For space applications, nuclear reactors are aiming to propel a spacecraft to distant objects in the solar system and beyond, in addition to producing power for Lunar or Martian crew habitats and machine operations. To achieve next-generation space architecture goals, several engineering hurdles must be resolved. In this talk, we will be discussing the research, design, and development of next-gen nuclear reactors with a focus on multi-scale multi-physics simulations.


Bio: Dr. Vedant Mehta is a computational multiphysicist in the Nuclear Engineering and Non-proliferation division at the Los Alamos National Laboratory. His focus is on designing and understanding advanced moderated reactors for numerous applications. He is enhancing high-fidelity multi-scale multi-physics tools to accurately predict reactor performance during normal and off-normal conditions. He is the inventor and principal developer of MARM software suite. His tools are being utilized by several national programs including NASA, industry and DoD. He is the ‘reactor modeling & simulation lead’ of DoD’s DRACO program, and ‘Design and Analysis’ lead of NASA’s Fission Surface Power and NASA’s Nuclear Electric Propulsion programs.
