Design and Modeling Needs of Nuclear Thermal Propulsion Systems
 

Abstract
This talk will cover the design aspects and modeling challenges associated with Nuclear Thermal Propulsion (NTP) systems. Nuclear thermal propulsion is a potential technology for future crewed missions to Mars due to its high thrust, and high specific impulse (Isp). This technology is expected to enable reduced interplanetary travel times, which could increase the crew's safety by reducing exposure to cosmic radiation and other hazards of deep space travel. Dan Kotlyar’s research group is working with the industry and national labs to support further research in NTP technology by developing a computational multiphysics framework that will allow a better understanding of the operational limits, reliability, and associated safety margins of the engine.

Bio
Dan Kotlyar, Associate Professor in the Nuclear and Radiological Program School of Mechanical Engineering, received his PhD in nuclear engineering in 2014 from Ben-Gurion University. In 2014, he joined the University of Cambridge as a Research Associate in the Engineering Design Center. In 2014, he was elected as a Research Fellow at Jesus College. He is the recipient of the NRC Faculty Development Fellowship, and Early Career Reactor Physicist Award by ANS for novel contributions to coupled Monte Carlo depletion and multi-physics simulations and their application to advanced reactors design. Kotlyar’s research lies in the field of advanced nuclear reactor design and multiphysics analysis. His Computational Reactor Engineering Laboratory (CoRE) focuses on developing the next generation production tools as well as designing advanced and low-cost nuclear energy systems. His research also includes optimization of fuel cycles in terms of fuel utilization and costs.
