| Abstract Scope |
Researchers have been using thermal convection loops (TCLs) since the 1950s. By imposing a temperature difference between a hot leg and a cold leg, TCLs can be used to recreate the mass transfer that occurs as the solubility of species in the flowing salt shifts with temperature. For this work, 316H stainless steel coupons were exposed for 1000h in a 316H thermal convection loop filled with purified FLiNaK salt. The loop was operated with a maximum hot leg temperature of 650°C, and a cold leg minimum temperature of 540°C. This talk will present the results of this most recent TCL experiment, along with TRANSFORM (TRANsient Simulation Framework Of Reconfigurable Models) modeling to better understand the properties that affect mass transfer. Historical context will also be given and future plans for material compatibility testing in flowing molten salts will be discussed. |
