Atomistic molecular dynamics and kinetic Monte Carlo simulations were used to investigate the role of He in point defect cluster behaviour and damage accumulation in body-centered cubic Fe. The goal of the simulations was to study the mechanisms responsible for the formation of vacancy-He clusters which served as He bubble and void nuclei in fusion reactor materials.
