  • The challenge of advanced materials for the plasma-facing blanket of the fusion reactor
    Vekinis, George
    As the thermonuclear fusion reactor is gradually becoming a reality, the challenge of developing suitable materials to enable efficient and long-term reliable operation at high temperatures is ... becoming more and more crucial. The new experimental reactor ITER, recently approved for construction at Cadarach, in France, will utilize Reduced Activation (RAFM) steels for the internal plasma-facing blanket and there fore the operating temperature of the heat-exchanging system will need to be kept as low as 500 [compositum]C, with significant losses in overall efficiency. To ensure competitiveness of any future commercial fusion reactors, the efficiency must be very high, which means that operating temperatures need to be maintained at more than 1000 [compositum]C over extended periods, without undue losses in mechanical and physical integrity and properties of the plasma-facing materials under high-energy neutron irradiation. These conditions, as well as the need to ensure non-activation of the materials (a condition only partially met by RAFM), presents a major material challenge, only recently being addressed worldwide. The talk will review the current state of affairs in this area and present some of the latest developments in materials being studied for this application, especially the SiC/SiC fiber composites.
