Structural materials for nuclear fusion energy : Development status and perspectives
This paper presents an overview of the development status and the perspectives of austenitic stainless steels, martensitic stainless steels, vanadium alloys and fibre reinforced ceramic composites (SiC/SiC), which are the materials currently investigated for fusion reactor application. Limitations and possibilities of their use are examined, with reference both to the next experimental reactor ITER (International Thermonuclear Experimental Reactor) and to the future reactor DEMO (Demonstration Reactor). Whilst for the experimental reactor ITER research is directed towards the optimisation of existing materials such as austenitic steels, ceramic matrix composites appear to offer enormous potential as structural materials for future commercial reactors, due to their high-temperature properties, low density, low thermal expansion and very low neutron activation.
