Abstract Scope |
Uranium with 10wt% molybdenum (U-10Mo) has been recognized as a promising candidate to replace high-enriched uranium fuel due to its ability to meet the neutron flux demands of U.S. high power research reactors. Manufacturing the U-10Mo alloy involves a complex series of thermomechanical processing steps. As part of this study, several models have been developed for the individual processes. The coupling between individual processes uses the concept of ICME which aims to bridge the information passing between interacting models and investigates the impact of manufacturing processes on material microstructure evolution. To enable fast prediction and optimization of U-10Mo properties, a data-driven surrogate model has been developed using the established simulation data. The simulated microstructures cover a wide range of initial grain size, uranium carbide volume fraction, and rolling reductions. This data-driven surrogate model demonstrates good accuracy in predicting the U-10Mo fuel microstructures and guides the selection of proper processing parameters.
