Abstract
Significant progress has been made recently in the development of HFIR LEU core designs. Much of this success is due to major enhancements in the HFIR modeling and simulation tools including developing high-fidelity neutronics models, streamlining the neutronic and thermal-hydraulic simulations via scripting, and the development of RSM-based optimization tools. Because the LEU design space is so large and the introduction of large amounts of 238U results in increased self-shielding effects, converting a compact, high-power density core like HFIR to LEU fuel is a challenging task. A few designs were presented in this paper that meet and exceed HEU-like performance. Following the completion of this phase of design studies, ORNL will present several designs and results to the stakeholders and the RC, FF, and FQ conversion pillars to aid in decisions regarding fuel down-selection and next steps.
