Keywords:FeCrAl-ODS Steels, Mechanical properties, Microstructure, strengthening mechanisms

We are pursuing research and development on the advanced stainless-steel fuel cladding tubes with high accident tolerance to use in BWR. In this presentation, as a part of the series presentation, the mechanical properties of FeCrAl-ODS steel materials and the contributing strengthening mechanisms were studied.
