Nuclear fusion is a promising candidate for a sustainable, climate-neutral and hazard-free base load power supply of the future. One of the major challenges for the operation of a future fusion reactor is the power exhaust. In order to reduce the temperatures and peak power loads at the plasma facing components, an intentional injection of impurities into the plasma – so-called impurity seeding – is applied. In this work it is investigated, how argon and nitrogen impurities in the experimental ASDEX Upgrade tokamak affect the plasma conditions, with a focus on numerical investigations using the SOLPS 5.0 fluid plasma code.
