In this episode, we discuss... (1) The importance of optimizing the secondary side design to remain competitive in today’s nuclear landscape (2) The interdisciplinary nature of the nuclear field and the shift in the reactor design process to focus on economics and safety (3) The economic conclusions from Koroush’s small reactor design research and how lower source terms mean less stringent NRC requirements (4) The factors that determine the number of fuel cycles and the decision to reuse fuel
