Abstract
  • The Accident Tolerant Fuels campaign demonstrated a need for nuclear fuel pin simulators to further research fuel and cladding combinations that can withstand off normal conditions in light water reactors. The use of a heater rod as a fuel pin simulator greatly reduces the risk involved during testing as no radioactive particle are present and insight can still be gained into ideal fuel and cladding combinations. Presently, no commercial heater rod exits capable of producing the heat fluxes required to match the off normal conditions. This study aims to determine the feasibility of producing a heater rod that can perform as a nuclear fuel pin through the use of computational fluid dynamics, physical prototyping and testing, and comparison of figure of merit. The final design underperformed when compared to the target metrics yet many insights were gained about the design approach and analysis methodologies.
