Influence of the divertor plate material on the plasma performance in DEMO

I. Ivanova-Stanik, R. Zagórski2015年被引用 4Nuclear FusionIF 3出版社

This paper describes integrated numerical modeling applied to DEMO discharges with different divertor plate materials (nickel, molybdenum and tungsten) in a slab geometry, using the COREDIV code. Calculations are performed for the inductive DEMO scenario with argon seeding. Simulations shown that for Mo and Ni, it is possible to achieve H-mode plasma operation (power to SOL power threshold for L–H transition) with acceptable levels of power to the target plates.
