Ab initio simulations were used to evaluate the interaction strength of typical interstitial impurities with self-interstitial atoms, dislocation loops and edge dislocation lines in tungsten. The relevance of the study lies in the application of tungsten as first wall material in fusion reactors.
Ab initio simulations are employed to assess the interaction of typical interstitial impurities with self-interstitial atoms, dislocation loops and edge dislocation lines in tungsten. These impurities are present in commercial tungsten grades and are also created as a result of neutron transmutation or the plasma in-take process. The relevance of the study is determined by the application of tungsten as first wall material in fusion reactors. For the defects with dislocation character, the following ordering of the interaction strength was established: H
