Abstract Scope |
Generation IV reactors use advanced designs with high fuel burnups which can lead to damage levels greater than 200 dpa. FM steels are candidate materials for such high dose applications because of their swelling resistance which has lead to significant interest within DOE and commercial businesses to explore the feasibility of advanced manufacturing (AM) of these materials. Due to the nature of the AM process, there is prima facie reason to hypothesize that FM steels fabricated via AM will have significantly different degradation mechanisms and kinetics compared to their wrought counter parts. This talk will focus on some of the fundamental and engineering aspects of degradation mechanisms (ion beam damage in particular) in commercial FM steels fabricated using state-of-the-art additive manufacturing techniques. In addition, this talk will also set the stage for future R&D activities towards development of FM steel variants tailored specifically for high dose applications using AM techniques. |
