| Abstract Scope |
Additive manufacturing (AM) has been proposed as a multifaceted approach to high throughput and material characterization and testing to relate print parameter, print orientation, sample, and thermal histories to relevant nuclear reactor performance properties. Continuous research in AM has propelled it to revolutionize the manufacturing industry due to the unparalleled design flexibility of the build process that allows rapid innovation of complex parts. Reactor parts are required to meet structural material qualifications meaning AM parts must be able to withstand off-normal reactor events involving steam exposure, in light water reactors as well as some advanced reactor designs. This study presents the characterization of oxidized AM 316LSS when exposed to high temperature (600°C<T<1000°C) steam (<65% pH2O) atmospheres. Raman spectroscopic analysis determines the chemical composition of the polished/passivated surface oxides that form on samples. Scanning electron microscopy provides microstructural characterization of surface and cross-sectional features of the oxide films and pitting defects. |
