Modeling the Far SOL region for ITER SRO scenarios using EMC3-EIRENE

ORAL

Abstract

Far SOL plasma profiles, including the temperatures and particle fluxes along the first wall, are compared for a series of EMC3-EIRENE SOL simulations. With respect to previous efforts, EMC3-EIRENE modeling capabilities for ITER are advanced to include an extended simulation domain spanning the entire SOL region up to the first wall, which is fully shaped to include toroidally non-axisymmetric beveling of tiles and vessel ports. Target L-mode (BT=5.3 T, IP=15 MA) and H-mode (BT=2.65 T, IP=5 MA) Start of Research Operation (SRO) plasma configurations are modeled. For each configuration, simulations are completed with a small and large anomalous transport coefficient assumptions for the far SOL region: D=1.5 m2s-1, χ=3 m2s-1 and D=3 m2s-1, χ=6 m2s-1. The sensitivity to this key SOL modeling uncertainty is compared to SOLPS-ITER simulations, showing reasonable agreement.
