Reactive atmosphere fabrication of nanostructured alumina-forming austenitic alloys for nuclear applications

Although advanced austenitic alloys are advantageous in non-nuclear applications due to their high creep strength, designing irradiation-resistant austenitic alloys is challenging due to the difficulty of dispersing irradiation defect-capturing sinks uniformly throughout the material. In this work, nanostructured alumina-forming austenitic (NAFA) alloys were successfully p…

A comparison of wrought and powder metallurgical FeCrAl claddings under simulated LWR accident transients

Iron-chromium-aluminum (FeCrAl) alloys are potential accident tolerant fuel (ATF) cladding candidates for light-water reactors but are difficult to fabricate as thin-walled tubes via conventional cast-and-wrought routes. Powder metallurgy (PM) offers a manufacturing alternative with improved compositional control, but its transient accident performance has not been directl…

Report on Preliminary Detailed Experimental Plan for Neutron Irradiation of A709 at ATR and HFIR

Advanced nuclear power technologies will use higher temperatures as a means to extract energy at a higher efficiency than current plants and therefore put a larger demand on the structural materials. Improved performance of structural materials could enable greater safety margins, longer plant lifetimes, and reduce maintenance costs. Alloy 709 is championed as the next gen…
