ITER as the next-level fusion device is intended to reliably produce morefusion power than required for sustainably heating its plasma. Modeling hasbeen an essential part of the ITER design and for planning of futureexperimental campaigns. In a tokamak or stellarator plasma discharge,impurities play a significant role, especially in the edge region. Residualgases, eroded wall material, or even intentionally seeded gases all heavilyinfluence the confinement and, thus, the overall fusion performance. Nitrogenis such a gas envisaged to be seeded into a discharge plasma. By modeling theimpurities kinetically using the full three-dimensional Monte-Carlo codepackage EMC3-EIRENE, we analyze the distribution of nitrogen charge-stateresolved in a seeded ITER baseline scenario and draw conclusions for thehydrogen background plasma density. Lastly, we compare the influence of a morerefined kinetic ion transport in EIRENE including additional physical effectson the impurity density.
