Description

Estimates of the ITER first wall steady-state sputtering due to fast atoms are made based on the B2-EIRENE modelling of the scrape-off layer (SOL) plasma. Models with fully diffusive and convective cross-field transport in the SOL are investigated. It is found that strong radial convection in the far-SOL has only a weak effect on the plasma profiles there. Effective yields of the physical sputtering of Be, C, Mo and W as well as their corresponding erosion rates at the first wall are calculated. The results are compared with available published data.
