Abstract : We report in this contribution on the development of an analytic model for a selfconsistent determination of the poloidal asymmetry, collisional flux and steady state profile of heavy impurities [1]. The model is compared with nonlinear axisymmetric simulations with the XTOR code [2, 3, 4], and with computations using the drift-kinetic code NEO [5]. An application to Tungsten peaking in the WEST tokamak under Ion Cyclotron Resonance Heating (ICRH) exemplifies the complex balance between accumulation and expulsion forces at play.
