Redox Run, Flibe UF4 with Hypo and Hyper Stochiometric F content - ondrejch/Molten_salt_chemistry GitHub Wiki

We know that one of the greatest determining factors in a salts corrosivity is its Redox state, measured/understood as its Florine Potential. This Potential is expected to shift throughout the operation of an MSR or when a salt is irradiated. This shift is largely caused by the diffence in valence states between U and its fission products. Other reasons for shift might include the release of F2 gas from radiolysis or the loss of F to transmutation. A reasonable indicator of F potential is known to be UF3-UF4 ratio. In this Sanity check, We will observe predicted behavior for the salt as if it we perfectly pure but made with more or less F than is required Sochiometricly.

Planed Simulation

  • We are most interested in temperature and F ratio, we will keep Pressure Constant for this case.

Temperature Range: 600 - 1200 K Composition Range:

  • Extreme HypoStoch. Uranium Pellet into Pure Flibe
  • 0.1 - 25 % HypoStoch.
    • Calculated as New F = Stoch. F - Per. Change * (Stoch. F)
  • 0.1 - 25 % Hyper Stoch.
    • Calculated as New F = Stoch. F + Per. Change * (Stoch. F)
