description: The subject of the graduate qualification work is âModeling of EU-DEMO edge plasma with argon and neon seedingâ. This work is devoted to modeling of EU-DEMO scrape-off layer. EU-DEMO is a prototype of a thermonuclear power plant. To prevent tungsten sputtering power loads to EU-DEMO divertor must be lower than 5 MWÂ·m-2 and the electron temperature must be lower than 5 eV. Also the sputtered tungsten flux must be lower than ÎW= 2.5Â·1019Â c-1Â·m-2. ITER scrape-off layer modeling shows that radiative impurity seeding and deuterium pressure increasing lead to better plasma performance in the ITER divertor region. This Master thesis presents first SOLPS-ITER modeling of EU-DEMO scrape-off layer plasma with drifts and kinetic neutrals. Modeling results contain cases with argon and neon seeding with various deuterium puff rates. The work demonstrates that drifts impact on impurity destribution in the scrape-off layer plasma. Plasma temperature at the outer divertor target is higher in cases with icluded drifts. Drifts also play a role in argon accumulation on inner midplane. Moreover, a case with higher neutral deuterium pressure demonstrates the best divertor performance. Another result of the work is that argon is better than neon as a radiating impurity.
