| Abstract Scope |
Kairos Power is developing the Fluoride-cooled High Temperature Reactor (FHR). FHR system development requires a comprehensive test and qualification program covering fuel, materials, coolant, and components. The structural material for use in the FHR is 316H, which has demonstrated low corrosion rates in the LiF-BeF2 (Flibe) primary coolant salt, provided chemistry of the salt is maintained during in-service use to reduce free fluorine. This presentation will provide an overview of the current ongoing technology development at Kairos Power and cover topics related to materials corrosion and mechanical properties tests in molten salt and analysis techniques Kairos Power materials and salt, and relevant interactions between molten salt and KP-FHR materials. The molten salt environments include both Flibe and nitrate (solar thermal) salt. Relevant test methods to be discussed include crack growth rate measurements using potential drop methods and susceptibility to stress corrosion cracking as well as corrosion behavior and the effects of chemistry control methods. |
