Metallic dust transport simulations for ITER and DEMO

Abstract: Beryllium and tungsten dust transport is simulated for ITER and DEMO using the dust transport code MIGRAINe. By combining many single-particle simulations a statistical analysis is performed. From that, the evolution of the dust inventories in the reactors is studied. Additionally, predictions are made for the locations at which dust evaporates. Finally, simplified analytical models with a few parameters for fast estimations of the dust inventory evolution are proposed. In the future, these could be integrated into more global models that also take into account dust generation.
