| Abstract Scope |
There is considerable interest in molten salts for concentrating solar power (CSP) and nuclear applications. The most important assessment of salt compatibility is in a flowing, non-isothermal experiment and thermal convection loops (TCLs) have been used for decades to provide compatibility data. For the CSP application with commercial MgCl2-KCl-NaCl salt, small mass changes were found with both purified (>500 ppm O) salt and when the salt was only dried. Classic dissolution-precipitation behavior was observed after 1000 h operation for both NiCr alloys 600 and C276 in an alloy 600 TCL with a peak temperature of 700°C and no degradation of the room temperature tensile properties was observed. For a nuclear application, a TCL is being constructed from type 316H stainless steel for operation with FLiBe salt and a peak temperature of 650°C is targeted. Results will be presented after 1000 h operation. |
