ITER will be equipped with a very sophisticated
From the prize-winning paper comparing simulation (using the MEMOS-U code, a much upgraded version of the MEMOS-3D package originally developed at KIT) with two fast-transient-induced tungsten melting experiments on ASDEX Upgrade (upper) and JET (lower). The excellent quantitative reproduction of the key features of the empirical deformation profiles demonstrates that the model adequately accounts for all the key physical processes.
Supported in part by the ITER Organization through contracts and co-sponsorship of graduate students, together with funding from EUROfusion and the Swedish Research Council, the KTH team began by refining and adding physics to the KIT simulation tool, guided by results from the older JET exposures and new similar, but better diagnosed, experiments on ASDEX Upgrade. The result was the
From a new paper just submitted to Nuclear Fusion by the KTH group, this is an example of the new MEMENTO melt code applied to the simulation of a dedicated experiment performed at ASDEX Upgrade designed to study the flow of molten tungsten over castellation gaps in plasma-facing components (of which there will be hundreds of thousands in ITER).
