About the project

Liquid metal plasma-facing materials are mixed-state composites that are designed for employment in fusion reactors. Despite the technological importance, the long-term integrity of such composites in high energy neutron radiation environments is uncertain, where especially the aspect of radiation and impurity is a major concern for the integrity. The purpose of this project is to confront the critical gaps in the current knowledge of the embrittlement of liquid metal plasma-facing materials and its impact on mechanical properties. To address these issues, we aim to design and implement a novel multi-scale modeling approach that utilizes atomistically-informed deep learning to describe constitutive behaviour. It will be used to explore and quantify the joint impact of neutron radiation damage accumulation and impurity segregation on the reduction in the load-carrying capability of fusion reactor materials.
