Researchers will make recommendations for design features of salt-reactor components that would take advantage of the phenomena characteristic to fluoride salts in order to be resilient to overcooling, and to recover gracefully from over-cooling transients. In support of this task a MOOSE-based computational tool will be developed, capable of modeling liquid-solid phase change, backed by experimental studies with the prototypical (flibe) coolant, and with simulant fluids.​​

Researchers will generate computational fluid dynamics (CFD) validation data for forced, mixed, and natural convection through a parallel-path geometry relevant to gas reactor bypass flow. In addition, the team will independently build and validate CFD models based on the experimental results. The team has the experience and existing infrastructure for sharing complete validation datasets.​​

*Actual project funding will be established during the award negotiation phase.​
