Recently additive manufacturing (AM) is revolutionizing nuclear energy sector with its unique capabilities in fabricating complex components, tailored microstructure and material flexibility. The majority of research thrusts leveraging AM technologies for nuclear energy are focused on new alloy development, structural integrity enhancement, greater design flexibility and standardization of AM parts. However, there is a huge opportunity to engineer surfaces of nuclear energy components via unique capabilities of AM processes that can help enhance their mechanical, irradiation, corrosion and fretting behavior during operation. Hence, there is a growing interest in the use of AM for surface engineering of metallic components in the nuclear sectors via various AM processes including surface texturing, repairing, coating as well as building AM parts with varied deposition schemes at near surface regions. Some examples are development of oxide dispersion strengthened steels for accident tolerant fuel cladding operations using directed energy deposition (DED) and cold spray technologies, enhancing high temperature fretting wear resistance of nuclear components by select high entropy alloy coating via L-DED process and application of combining laser shock peening, laser peening or ultrasonic noncrystalline surface modification processes with AM technologies to improve the service life and safety of canisters used in nuclear sector.
This symposium will have two main themes. The first theme will emphasize the advanced manufacturing efforts to engineer surfaces of nuclear energy components for enhanced reliability. Abstracts will be requested in, but not limited to, the following areas: advancements in additive and hybrid manufacturing systems, microstructure evolution, mechanical behavior and case studies demonstrating the nuclear applications enabled by specific AM process. The second theme will emphasize performance evaluation in this area. Abstracts are requested in, but not limited to, the following areas: understanding the effects of surface engineering on fretting, corrosion, irradiation behavior, and constitutive models to predict the aforementioned properties. |
