| Abstract Scope |
High-precision quantification of oxygen and hydrogen in FLiBe salt is critical for effective molten salt chemistry control, tritium extraction, and ensuring materials compatibility in the ARC fusion power plant, where FLiBe serves as the liquid blanket. In this study, a customized gas combustion system was employed to measure the oxygen and hydrogen content in post-melted FLiBe salt. The system features a furnace and sample-loading mechanism housed within an argon-filled glovebox to prevent contamination and air exposure. In parallel, an electrochemical method was developed to enable real-time detection of oxygen and hydrogen species in the form of oxides and hydrides in static molten FLiBe. This presentation will also discuss the key insights gained from both approaches, with emphasis on improving the measurement repeatability and reliability. |
