Understanding the behavior of impurities in the SOL is important because distribution of impurity ions in this region influences their transport to the H-mode pedestal and further to the core [1 and references therein]. In the present paper the modeling of plasma edge is made with the SOLPS-ITER transport code [2] for ASDEX Upgrade tokamak with nitrogen seeding. The distribution of the nitrogen in the SOL and private region (PR) is analyzed.
