| Abstract Scope |
This study presents corrosion testing of 316 stainless steel (SS316) in molten LiCl-KCl under controlled flow conditions using a custom flow loop testbed at Idaho National Laboratory (INL). A 500-hour high-temperature exposure was conducted with continuous molten salt circulation over SS316 coupons under well-characterized thermal and flow profiles. The system integrates in-line electrochemical sensors for real-time monitoring of salt chemistry, providing insight into corrosion kinetics and redox behavior. Periodic salt sampling and analysis via inductively coupled plasma (ICP) techniques quantified dissolved metal species and validated electrochemical data. The presentation will highlight the INL flow loop design, test conditions, corrosion behavior of SS316 in dynamic salt environments, and correlations between electrochemical signals and ICP analysis. These results support the development of effective corrosion monitoring approaches and inform material selection for advanced nuclear and thermal energy systems operating with molten chloride salts. |
