Abstract

The long term development of fusion materials in the European Union for the construction and operation of future fusion power reactors focuses on structural materials such as Reduced Activation Ferritic Martensitic (RAFM) steels, of which the EU reference material is EUROFER, Oxide Dispersion Strengthened (ODS) RAFM and RAF steels, SiCf/SiC composites, tungsten (W) and W-alloy and functional materials such as Li based ceramics, liquid Pb-15.7at%Li, Be, plasma facing materials and, anticorrosion and antipermeation layers. The structural materials are developed for specific applications and have to satisfy specific requirements with respect to radiation resistance, low activation, high creep strength and good compatibility with all contact media in an as wide as possible operational temperature window. The functional materials should not only have some of these properties, but must fulfill the required functions of: tritium breeding, neutron multiplication, efficient heat transfer, low corrosion and a limited hydrogen permeation rate. An overview of the status of present developments, recent achievements and open issues of these fusion materials is presented here..
