Plasma-facing materials and components in a fusion reactor are the interface between the
plasma and the material part. The operational conditions in this environment are probably
the most challenging parameters for any material: high power loads and large particle and
neutron fluxes are simultaneously impinging at their surfaces. To realize fusion in a tokamak
or stellarator reactor, given the proven geometries and technological solutions, requires an
improvement of the thermo-mechanical capabilities of currently available materials. In its
first part this article describes the requirements and needs for new, advanced materials for the
plasma-facing components. Starting points are capabilities and limitations of tungsten-based
alloys and structurally stabilized materials. Furthermore, material requirements from the
fusion-specific loading scenarios of a divertor in a water-cooled configuration are described,
defining directions for the material development. Finally, safety requirements for a fusion
reactor with its specific accident scenarios and their potential environmental impact lead to
the definition of ... mehr
