| Abstract Scope |
(LiF)<sub>0.67</sub>(BeF<sub>2</sub>)<sub>0.33</sub> (denoted as “Flibe” when it meets Kairos Power's specifications) is the primary coolant for the Kairos Power - High Temperature Fluoride Reactor (KP-FHR), a Generation IV nuclear power reactor. The Flibe transports heat from solid nuclear fuel in the KP-FHR to a secondary nitrate solar salt [(NaNO<sub>3</sub>)<sub>0.64</sub>(KNO<sub>3</sub>)<sub>0.36</sub>] through a heat exchanger. Chemical reactions between these two salts is of interest because of possible leaks between the primary and secondary sides of the heat exchanger. This work observed an endothermic, kinetically slow, gas-evolving chemical reaction when Flibe and nitrate solar salt were melted separately and then rapidly combined. Thermodynamic modeling of this chemical interaction and the experimental confirmation of the modeling will be presented. |
