IAEA supports and promotes activities crucial for the global development of fusion power reactors. Understanding the physics of fundamental processes on plasma-wall interactions (PWIs) and plasma-material interactions (PMIs) is a necessity for the R&D of optimised reactor components in the plasma-facing areas as well as structural components. In support of this, IAEA establishes and maintains internationally recommended fusion databases on various PWI and PMI processes relevant for materials used in the reactor components. The International Workshop on Models and Data for Plasma-Material Interactions in Fusion Devices (MoD-PMI) discusses the underlying effects and related data and is organized in cooperation with the IAEA for the seventh time. It brings together researchers and scientists from the areas of fusion energy and materials science to review advances in modelling of processes relevant to PWI and PMI in fusion devices.

The MoD-PMI workshop aims to provide a bridge between fundamental computations and interpretation of experimental data; it will address a variety of processes spanning a wide range of scales including erosion, transport and trapping of fusion fuel species in the wall, changes and evolution in the material microstructure, composition and morphology. The workshop format is to encourage new collaborations on computational and experimental studies of plasma-material interaction in fusion devices.
