Project
A concerted effort over the past few years has focused on enhancing the core depletion models for the High Flux Isotope Reactor (HFIR) as part of a comprehensive study for designing a HFIR core that would use low-enriched uranium (LEU) fuel. A HFIR core depletion model that is based on current state-of-the-art methods and nuclear data was needed for use as a reference for the design of an LEU fuel for HFIR and to improve the basis for analyses that support HFIR’s current operation with high-enriched uranium (HEU) fuel. The developed high-fidelity computational models are used to perform parametric studies, optimization, and assessments for HEU and various LEU configurations.
Benefit
Support the design of a compatible HFIR LEU fuel that can be fabricated and meet performance and safety requirements. Provide a robust and reliable basis for depletion analysis of any HFIR core and design and analysis of experiments in HFIR.
