4. Currently work is planned at UAH and NASA for higher fidelity core dynamics models [43-45]. To further the effort towards these models the authors plan to develop a thermochemical model to account for propellant / fuel interactions incorporating residency time to account for cermet formation, carbon buildup, and fuel pollution. Experimental efforts are also underway at UAH to better define the mixing and secondary flow characteristics within the core to further inform the fluid dynamics models and thermochemical models [46]. Lastly, a transient state core and systems model is in development to quantify the fuel burnup and fission product generation which will then be fed back into the thermochemical model to further increase fidelity of the systems model.
