| Abstract Scope |
Traditional empirical approaches to material qualification face significant challenges, especially with the advent of additive manufacturing (AM) and the near-term deployment of advanced reactors with a wide range of temperature and neutron irradiation (spectrum, flux, fluence) conditions. Examining radiation effects requires a significant amount of space and time in US nuclear reactor test facilities. Ion irradiation may enable rapid assessment of radiation-induced damage to a material. This presentation focuses on recent neutron and ion irradiation results obtained for AM 316L and AM 316H through multi-length scale characterization. The integration of modeling techniques that correlate ion and neutron irradiation data help interpret and predict microstructure evolution at higher damage levels. By comparing these results, we demonstrate the effectiveness of pairing ion irradiation and modeling efforts with a limited set of neutron irradiations to achieve accelerated qualification. |
