ABSTRACTThe role of oxide nanoparticles in cavity formation of a nano-oxide-dispersed ferritic steel subjected to (Fe + He) dual-ion and (Fe + He + H) triple-ion irradiations has been studied using transmission electron microscopy to elucidate the synergistic effects of helium and hydrogen on radiation tolerance of nano-oxide-dispersed ferritic steel for fusion energy systems. The effect of oxide nanoparticles on suppressing radiation-induced void swelling is clearly revealed from the observation of preferred trapping of helium bubbles at oxide nanoparticles, which results in a unimodal distribution of cavities in the (Fe + He) dual-ion irradiated specimen. An adverse effect of hydrogen implantation, however, is revealed from the observation of a bimodal distribution of cavities with large and facetted voids in association with the formation of HFe5O8-based hydroxide in local regions of the (Fe + He + H) triple-ion irradiated specimen.

In a global effort, the key players have combined their R&D forces to work jointly on the next generation thermonuclear fusion device. The development of structural, heat-sink and armor materials for plasma interactive components is focusing on neutron irradiation damage, and its impact on property retention and component integrity. Consequently, the processing of materials, realistic component testing methods as well as modeling are being optimized to suit the newest design concept(s). Nondestructive inspection of components is now available at an accuracy needed to ensure long service in a harsh, nuclear environment. The most promising materials and best established manufacturing processes are described; the proposed qualification techniques for fusion in-vessel and heat removal systems are reviewed.
