| Abstract Scope |
Large metal components have traditionally been produced from castings, forgings or assemblies. The need for replacement or repair of these components is increasing with the aging fleet. This demand, combined with the demand for new builds challenges the industrial capacity. Additive manufacturing using wire and direct energy deposition can fill this void.
This talk will review the properties of additively deposited metals and explore the state of large-scale additive manufacturing. It will outline the code and regulatory requirements for use of additively-manufactured material in nuclear applications.
Finally, it will focus on some of the unique possibilities that can be achieved by utilizing additively-manufactured material. These include using various shapes and thicknesses to achieve the appropriate strength, toughness and fatigue resistance without excessive material. They also include design and composition variations to address ease of fabrication, installation and dissimilar metal welds. |
