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 shape of the 6Li(n,α)T cross-section curve has been measured from 3- to 800-keV neutron energy. The neutrons were produced by the National Bureau of Standards 140-MeV Linac, and the measurements were made along the 200-m above-ground drift tube. The neutron flux was monitored by a 61-cm-long hydrogen gas proportional counter giving a direct ratio of the 6Li(n,α) cross section to the H(n,p) cross section. The 6Li(n,α) events were detected in a 0.5-mm-thick piece of 6Li glass (NE-912). The results were normalized to ENDF/B-V in the region from 10 to 100 keV. Overall uncertainties in the measurement are ∼2% in the range from 10 to 400 keV. Error analysis and comparisons with previous measurements are given.
