The Stable Salt Reactor: Transforming the promise of the molten salt fuel concept into a viable technology

Figure 2. Equilibrium concentration of dissolved chromium in fluoride and chloride based fuel salt. Stabilisation of the redox potential of uranium trichloride based fuel salt with sacrificial zirconium metal reduces its thermodynamic tendency to dissolve chromium from steel by 8 orders of magnitude compared to a uranium trifluoride based salt
