Abstract The difference of tungsten impurity transport characteristics between a high recycling regime and a partially detached regime has been studied with the IMPGYRO code. Background plasma profiles from a JT-60U model geometry, computed from SOLPS, have been used. To obtain such characteristic regimes, we have changed electron (Qe) and ion (Qi) input powers at the core boundary. In the high-recycling regime, the tungsten impurities are transported toward the upstream of the SOL. On the other hand, in the partially detached regime, most tungsten impurities are localized near the inner and outer divertors. These features are mainly related to the background plasma temperature and ion flow.
