| Abstract Scope |
Scaling radiation-resistant nuclear materials, which involve tailoring both chemistry and microstructure, from the lab to industrial scales, presents challenges. This talk examines how looser controls during scale-up lead to deviations in radiation tolerance. We assess this in Castable Nanostructured Alloys (CNAs) tailored for high MX-type precipitate density. We will compare two lab-scale heats, a 0.25-ton industry heat with varied controls, and a five-ton industry heat with three processing variants under ion irradiation across temperatures from 300 to 600°C, doses from 1 to 100 dpa, dose rates from 1x10⁻⁴ to 1x10⁻³ dpa/s with varying helium implantation rates. Our study confirms that the process-structure-property paradigm remains valid due to the coupling between precipitate-sink and cavity-precipitate evolution, resulting from complex interplays between sink strength and diffusion in tailored CNA alloys. This talk sets the stage for subsequent discussions on novel alloy development and lays the foundation for scale-up considerations of tailored nuclear materials. |
