Material degradation under DEMO relevant neutron fluences

In fusion power reactors, the plasma facing and breeding-blanket components will suffer intense irradiation by 14MeV neutrons. These high-energy fusion neutrons will produce atomic displacement cascades and nuclear transmutation reactions inside the irradiated materials, and these will result in important radiation damage and effects. In the present paper, typical examples of radiation damage and effects on candidate materials for plasma facing components in fusion power reactors are presented and discussed.
