Abstract Scope Additive manufacturing (AM) including directed energy deposition (DED) methods are being considered for production of nuclear reactor components. Here, the process-structure-performance (p-s-p) paradigm will be discussed for nuclear grade steels produced via DED-based AM technologies and exposed to high dose (e.g., ≥50 displacements per atom – dpa) ion irradiations. Specifically, the role of impurity contributions due to the AM process on radiation-enhanced clustering, the influence of post-build heat treatments on the swelling response, and the influence of co-injected helium on the loop formation and swelling in DED produced HT9 is considered. The conditions studied includes damages up to 250 dpa at 445C, and irradiation temperatures from 400C to 480C at 50 dpa. It will be shown that the p-s-p relationship in AM HT9 is highly sensitive to minor changes within the p-s-p factors, thus highlighting the additional complexities in considering high dose degradation phenomena in AM produced steels.
