Materials for fusion power plants Stéphane Forsik - Phase Transformations and Complex Properties Group www.msm.cam.ac.uk/phase-trans FUSION POWER PLANT The production of electricity from the fusion of deuterium and tritium is an alternative source to classical fission nuclear power plants but, as a lot of technical issues still have to be resolved, the first commercial fusion power plant is not expected before 50 years. The plasma of deuterium and tritium will reach about 100 million K and neutrons with an energy of 14 MeV produced during the reaction will strongly irradiate the materials constituting the first wall of the reactor. Average irradiation doses are expected to be about 200 displacements-per- atom (dpa) over a lifetime in service of several decades. The behaviour of materials in such a hostile environment is not well-known and the choice of a candidate material with the best mechanical resistance to radiation-induced hardening and swelling is crucial.
