| Abstract Scope |
The advance of additive manufacturing (AM) has made it possible for rapid prototyping and cost-effective production of high-quality nuclear components. As such, AM technologies are expected to not only help with the long-term sustainability of the current fleet, but also accelerate the development of advanced nuclear reactors. Yet, our current understanding on the cracking behavior of AM materials in service condition is limited. In this study, AM 316L stainless steel (SS) specimens extracted from Laser Powder Bed Fusion builds were examined for microstructure and porosity, and tested for fatigue and stress corrosion cracking (SCC) performance. For the AM materials, the fatigue behavior in air and the corrosion fatigue and SCC responses in water are comparable to that of wrought SS. Additional research needs on environmental fatigue, crack initiation, and SCC testing are discussed in the context of qualifying AM materials for regulatory acceptance and broader applications in advanced reactors. |
