Abstract :
Summary form only given. Erosion calculations of the first wall system during regular operation and during plasma disruptions were made. Estimates were obtained with the DISRUP code. Disruptions that could take place at the peak of the ignited phase of the IGNITEX discharge were considered. Plasma disruptions were simulated by means of detailed equilibrium simulations. Both thermal quench and current quench were considered. The thermomechanical stress levels in the first wall system of IGNITEX bring an ignited plasma disruption were evaluated. A fully three-dimensional finite-element stress analysis was conducted. It was assumed that the first wall material behavior is adequately characterized by a decoupled thermomechanical response. Both melting and evaporation of the coating material were included in the analysis. Computations were performed with the finite-element program ABAQUS
