Fluoride salt-cooled high-temperature reactors (FHRs) are an emerging reactor class that combines attractive attributes from previously developed reactor classes and power plants. FHRs by definition feature low-pressure liquid fluoride salt cooling, coated particle fuel, a high-temperature power cycle, and fully passive decay heat rejection. FHRs have the potential to economically and reliably produce large quantities of electricity and high-temperature process heat while maintaining full passive safety. Leveraging the inherent reactor class characteristics avoids the need for expensive, redundant safety structures and systems and is central to making the economic case for FHRs. Additionally, as a high- temperature reactor class, FHRs can efficiently generate electricity and provide the energy for high-temperature industrial processes (notably including the production of hydrocarbon fuel). High-temperature operation also increases FHR compatibility with dry cooling.
