Abstract Scope |
The manufacturing of low-enriched uranium alloyed with 10 wt% molybdenum (U-10Mo) involves multiple hot rolling passes and annealing steps after homogenization. The resultant microstructure depends on various casting attributes such as grain size, uranium carbide (UC) volume fraction, size, and distribution; and rolling reductions. Over 150 numerical simulations had been conducted using an integrated microstructure – based Finite Element – Monte Carlo Potts model framework. A sensitivity analysis using the stragihforward one-factor-at-a-time (OAT) method and multivariate adaptive regression spline (MARS) surrogate model was performed to analyze the influence of the model input parameters on the final grain size, distribution, and the recrystallized percentage. |
