Abstract Scope |
This presentation highlights two recent examples of applying the Calculation of Phase Diagram (CALPHAD) approach to nuclear materials design. In the first example, a thermodynamic database for the U-Mo-Ti-Zr quaternary system was developed based on inputs from both experiments and extensive ab initio calculations. The CALPHAD database was then used to identify a strategy for alloying pure U with metallic additives (Mo, Ti, and Zr) in order to produce advanced nuclear fuels with optimal fuel performance. In the second example, using the CALPHAD free energies of phases in the Fe-U binary system as inputs, a model based on analytical solution to the moving boundary Stefan problem was developed for predicting the penetration rate of eutectic liquids into cladding during fuel-cladding chemical interaction (FCCI). The model predictions compare favorably with the available experimental measurements. |
