Abstract

A global model is described which calculates the impurity levels resulting from plasma and impurity sputtering. The edge temperature is determined in a self consistent way from the input power and the particle containment time. Calculations are presented for the specific case of INTOR considering both carbon and iron walls. The impurity level is very dependent on the global particle containment time. For iron walls the impurity level is probably tolerable but a large fraction of the alpha heating power is radiated. For carbon walls the radiation level is much lower.
