A detailed study of the divertor performance in EAST has been performed for both its double null (DN) and single null (SN) configurations. The results of application of the SOLPS (B2-Eirene) code package to the analysis of the EAST divertor are summarized. In this work, we concentrate on the effects of increased geometrical closure and of magnetic topology variation on the scrape-off layer (SOL) and divertor plasma behavior. The results of numerical predictions for the EAST divertor operational window are also described in this paper. A simple Core-SOL-Divertor (C-S-D) model was applied to investigate the possibility of extending plasma operational space of low hybrid current drive (LHCD) experiments for EAST.
