Abstract Scope |
Low-enriched uranium alloyed 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 and initial experimental evaluations of irradiation performance. Manufacturing the U-10Mo alloy involves a complex series of thermomechanical processing steps, including homogenization, hot rolling, annealing, cold rolling, and hot isostatic pressing. As part of this project, several models/modeling methods have been developed for the individual processes. The interaction and coupling between individual processes use 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. The ICME framework is demonstrated by combining all the individual processes. It is shown that the implementation of ICME leads to improved predictions, better understanding of microstructure across multiple processes, and accelerated and more cost-effective development effort. |
