| Abstract Scope |
Actinide-bearing chloride and fluoride salts, such as NaCl-UCl3 eutectic, are used fuel in advanced molten salt reactor designs. The composition of the fuel salt changes over the lifetime of the reactor due to burnup, fission product buildup, refueling, and corrosion. Elsewhere, the effects of the introduction of fission products to NaCl-UCl3 fuel salt on its thermophysical properties are described. In this companion study, those same salt samples are studied for their corrosive effects on metals and alloys that may serve as structural materials. Three NaCl-UCl3 salt reactor states are measured; the initial eutectic feed salt, the equilibrium Na:U ratio composition salt, and the equilibrium Na:U ratio composition with the addition of modeling predicted fission products. The implications for redox control by uranium are discussed. |
