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. %G English %Z The WEST team %2 https://cea.hal.science/cea-03249460/document %2 https://cea.hal.science/cea-03249460/file/paperIAEA2020_maget_v3bis.pdf %L cea-03249460 %U https://cea.hal.science/cea-03249460 %~ CEA %~ X %~ CNRS %~ UNIV-AMU %~ X-CPHT %~ X-DEP %~ X-DEP-PHYS %~ OPENAIRE %~ PIIM %~ DSM-IRFM %~ CEA-DRF %~ CEA-CAD %~ IP_PARIS %~ IP_PARIS_COPIE
