Abstract Scope |
Finding suitable plasma-facing materials is one of the great challenges in designing future fusion reactors, as unprecedented particle and heat fluxes will interact with the first wall, compromising the performance of both the plasma and wall components. These plasma-material interactions involve diverse plasma and materials physics, and thus, are multi-scale in nature. To address this complex system, we have developed a validated, integrated computational model that interprets and predicts plasma-material interactions in plasma-facing materials. The model includes descriptions for the edge plasma, near-surface sheath, impurity erosion and redeposition, particle recycling, surface morphology and sub-surface evolution. Here, we present the latest applications of our model, which has already been used to interpreting experiments in current devices, such as WEST, to predicting the evolution of the ITER divertor under a range of operational conditions, as well as to exploring the impact of plasma impurities in fuel recycling. |
