Abstract
Austenitic stainless steels are widely used in current commercial BWR and PWR systems as in-core and
surrounding structural materials. These versatile steels have also been the main materials considered
and applied for many advanced reactor technologies, including fast-breeder reactors and magnetic
fusion reactors. For advanced reactors for higher-temperatures or high lifetime damage levels, modified
versions of the standard commercial stainless steel grades have been developed to provide improved
properties performance and radiation-resistance in specific reactor environments. An overview of the
unirradiated properties and a summary of some important radiation-induced properties changes are
presented. Highlights of several alloys developed for more radiation-resistance or better performance
in specific reactor environments are highlighted.
