We have just completed a comparison of predictions for the scrape-off layer (SOL) plasma, from a physics model [1] with the more accurate ones from a two-dimensional fluid code, the B2 code [2]. The results presented here show rather good agreement on values of plasma temperature in the SOL and of divertor heat load, for a rather wide range of Tokamak sizes and parameters. We are therefore confident that this model will provide a suitable divertor module for both the new ITER systems code, SUPERCODE [3], and other applications requiring fast but accurate modelling of edge plasma parameters, at least within the range of the present benchmarks.
