1. Researching a New Fuel for the HFIR: Advancements at ORNL Require Multiphysics Simulation to Support Safety and Reliability
Redesign High Flux Isotope Reactor (HFIR) to preserve performance, efficiency, and safety when converting from highly- enriched uranium (HEU) to low-enriched uranium (LEU) fuel
Use COMSOL software to simulate fluid-structure interaction (FSI) in the core to analyze different fuel plate configurations and predict flow rates and deformation
