CX-270268: Sodium-Cooled Fast Reactor Key Modeling and Analysis for Commercial Deployment – University of Wisconsin

The University of Wisconsin proposes to conduct a series of experiments with advanced temperature and fluid measurement instrumentation (optical fibers, ultrasonic Doppler imaging, magnetic flow sensors, and hot wires) to obtain high fidelity data on thermal striping and thermal stratification in liquid sodium. To achieve this, a series of three different geometries will be considered both experimentally and computationally. The project will then use models to analyze low Prandtl number (sodium) heat transfer, thermal stratification and thermal striping experiments. Data from these simulations will be compared to the experiments and used to help understand the fundamental characteristics associated with the thermal stratification and striping mechanisms.
