NSUF 17-1014: Radiation-Hardening and Microstructural Stability of NF709 Austenitic Stainless Steel

Austenitic stainless steel NF709 has been down-selected for development as a candidate structural material for sodium-cooled fast reactors. However, the understanding on its radiation resistance is limited to a few model or simplified alloys. To better understand radiation resistance of NF709, this project is to study radiation-hardening and microstructural evolution of NF709 irradiated up to 8 dpa in the temperature range of 430-470 °C. The outcome of this study will provide key insights to understand radiation resistance of Alloy 709 that is optimized from NF709 under the Advanced Reactor Technologies (ART) program.
