Abstract
In this work the scenario #2 for the JT‐60SA with a carbon divertor configuration is analysed by using the core‐edge integrated COREDIV code. A combined seeding with two impurities, high and low atomic number, is proposed for controlling the core and the scrape‐off layer radiation and limiting the total power delivered to the divertor plate. As a proof‐of‐principle tungsten and argon seeding is investigated due to successful results reported for the same scenario with W divertor. Replacing non‐recycling W by recycling Xe shows the influence of the recycling coefficient on the final solution. Also the location of the puffing nozzle was found to be a crucial factor for the final result.
