Abstract

Plasma facing components for tokamak fusion reactors will be exposed to fast neutron and plasma fluxes, and it will be also exposed to severe heat load conditions, especially during a plasma disruption. In order to estimate the erosion loss of a divertor plate, several physical processes have to be considered. In this study, the molecular dynamics method is applied to analyze melting and evaporation of solid wall with high energy particle injection. The analysis have been performed for a simulated system composed of argon and helium molecules and the vapor shielding effect which is caused by elastic collisions is analyzed.
