Abstract Scope |
Kairos Power (KP) is focused on development of the fluoride-salt-cooled, high-temperature reactor (KP-FHR), which uses 2LiF-BeF2 (known as Flibe) as the reactor primary loop coolant. Monitoring and control of Flibe chemistry is necessary for efficient long-term operations of KP-FHR. Oxidizing impurities (e.g. H2O, O2), from cover gas contamination or maintenance cycles, may drive corrosion and limit component lifetime, while accumulation of corrosion products (CrF2, FeF2, MnF2) in the salt can lead to undesired solubility-driven material deposition in the system. KP chemistry control focuses on addressing those phenomena by leveraging fundamental Flibe thermochemistry principles combined to an iterative testing approach for laboratory and engineering-scale Flibe systems. This talk presents KP approach to Flibe chemistry technology development and chemistry control in KP-FHR, with specific case-studies on fundamentals and applications of redox control, online and offline chemistry monitoring strategies, and chemistry of impurity ingress and removal from the salt. |
