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.

Recent studies have shown that available theoretical models for critical two-phase flows in simple nozzles are not able to predict observed data. To achieve agreement, it is customary to multiply the computed mass flow rates by empirically determined factors. In this paper, a two-dimensional theory is used to show that the deficiencies are associated with geometric effects not accounted for in the earlier models. The theory presented here is applied to both equilibrium and nonequilibrium situations with considerable success and supplies a rational basis for the use of break flow multipliers.
