Nuclear grade wrought FeCrAl alloy is currently under development as a candidate structural material for accident tolerant fuel cladding in light water reactors. Seamless thin-wall tube production of the FeCrAl alloys is a key target of the development, and it was initiated through commercially available tube production technology. Because of limited deformability nature of the FeCrAl alloys with strong dependence on minor alloying additions, the process development effort has been pursued with several key factors; proper alloy composition ranges, minor alloying additions, microstructure control prior to tube drawing process, area reduction ratio per pass, inter-pass annealing conditions, and so on. The detailed story of the quality optimization of the final tube production will be presented based on various characterization of the failure modes observed during tube production processes. This research was sponsored by US DOE, Office of Nuclear Energy, Advanced Fuel Campaign of the Fuel Cycle R&D program.
