Abstract In this paper we present integrated numerical modelling for the first time applied to ASDEX Upgrade nitrogen seeded discharges with full tungsten wall using COREDIV code. It has been found that code is able reproduce experimental data majority of considered shots. particular, satisfactory agreement global core parameters like P div , rad Z eff W mhd τE and Γ puff N found. However, shows significantly larger concentrations (factor 3‐10) than in experiment reason discrepancy not clear. Some plasma profiles are also reasonably simulated by This includes density, temperatures, radiations (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
