Abstract. It has long
been recognized that attainment of the safety and environmental potential of
fusion energy requires the successful development of low-activation materials
for the first wall, blanket and other high heat flux structural
components. Only a limited number of materials potentially possess the
physical, mechanical and low-activation characteristics required for this
application. The current U.S. structural materials research effort is focused
on three candidate materials: advanced ferritic steels, vanadium alloys, and
silicon carbide composites. Recent progress has been made in understanding the
response of these materials to neutron irradiation.
