The purpose of the present project is to investigate the mobility of dislocations in irradiated and transmuted tungsten alloys. Such knowledge is important for modelling failure in plasma-facing components in fusion reactors.
We will rely mainly on classical atomistic modelling, i.e. molecular dynamics and Monte Carlo modelling, but also some quantum mechanical density functional theory modelling, to gain insight behind the mechanisms and the impact of transmutation products on the mobility. Such knowledge serves as an important pillar to understand the gradual degradation of fusion reactor components over time and to make reasonable life-time predictions.
