COMPREHENSIVE MODEL FOR DISRUPTION EROSION IN A REACTOR ENVIRONMENT

A comprehensive disruption erosion model which takes into account the interplay of major physical processes during plasma-material interacti on has been developed. The model integrates with sufficient detail and in a self-consistent way, material thermal evolution response, plasma -vapor interaction physics, vapor hydrodynamics and radiation transpor t in order to realistically simulate the effects of a plasma disruptio n on plasma-facing components. Candidate materials such as beryllium a nd carbon have been analyzed. The dependence of the net erosion rate o n disruption physics and various parameters was analyzed and is discus sed.
