IAEA supports andpromotes activities crucial for the global development of fusion powerreactors. Understanding the physics of fundamental processes on plasma-wallinteractions (PWIs) and plasma-material interactions (PMIs) is a necessity forthe R&D of optimised reactor components in the plasma-facing areas as wellas structural components. In support of this, IAEA establishes and maintainsinternationally recommended fusion databases on various PWI and PMI processesrelevant for materials used in the reactor components. The InternationalWorkshop on Models and Data for Plasma-Material Interactions in Fusion Devices(MoD-PMI) discusses the underlying effects and related data and is organized incooperation with the IAEA for the seventh time. It brings together researchersand scientists from the areas of fusion energy and materials science to reviewadvances in modelling of processes relevant to PWI and PMI in fusion devices.

The MoD-PMIworkshop aims to provide a bridge between fundamental computations andinterpretation of experimental data; it will address a variety of processesspanning a wide range of scales including erosion, transport and trapping offusion fuel species in the wall, changes and evolution in the materialmicrostructure, composition and morphology. The workshop format is to encouragenew collaborations on computational and experimental studies of plasma-materialinteraction in fusion devices.
