Under the safety and environmental assessment of fusion power long-term programme (SEAL) an assessment was performed of a number of possible blanket structural materials. These included the steels then under consideration in the European Blanket Programme, as well as materials being considered for investigation in the Advanced Materials Programme. Calculations were performed, using safety and environmental assessment of fusion power (SEAFP) methods, of the activation properties of the materials, and these were related, based on the SEAFP experience, to assessments of safety and environmental (S&E) performance. The materials investigated were the SEAFP low-activation martensitic steel (LA12TaLC); a Japanese low-activation martensitic steel (F-82H), a range of compositional variants about this steel; the vanadium-titanium-chromium alloy which was the original proposal of the International thermonuclear experimental reactor (ITER) JCT for the ITER in-vessel components; a titanium-aluminium-intermetallic (Ti-AI) which is under investigation in Japan; and silicon carbide composite (SiC).
