UM conducts molten salt experiment
For 2,300 hours, the molten salt pump Shaft Seal Test Facility (SSTF) operated at the University of Michigan’s Thermal Hydraulics Laboratory, according to an article from UM. The large-scale experiment was designed to evaluate shaft seal performance in high-temperature pump systems. Fewer than 10 facilities worldwide have successfully operated fluoride or chloride salts for more than 100 hours using over 10 kilograms of material.

The space-dependent kinetics of a strongly coupled multiregion cylindrical reactor were studied both theoretically and experimentally. A three-node model was used to calculate the kinetic response in the various regions and these results were compared with two-detector noise measurements. Reasonable agreement was obtained for predicted and measured transfer functions, power spectral densities, coherence functions, and alpha, the ratio of the effective delayed neutron fraction to the prompt neutron lifetime. Differences in the kinetic response of the various regions were clearly evident.
