| Abstract Scope |
The rapid development of and increasing focus on advanced fission and fusion-based nuclear energy have called for design of novel materials solutions to address the various materials challenges in the harsh service conditions. This presentation provides overview of two materials and processing development efforts aiming to overcome the materials degradation issues in extreme nuclear applications. The first effort is development of cold spray-enabled bimetallic structures consisting of refractory-based molten salt resistant coatings on an ASME code-certified substrate for molten salt reactors, while the second focuses on design and fabrication of a functionally graded joint between RAFM steel and tungsten-based plasma facing component in fusion reactors via multi-hopper direct energy deposition (DED). Immersion corrosion results and surface characterization of the cold sprayed refractory coatings in representative chloride molten salts will be presented. The computational approach of intelligently designing an optimized gradient path between RAFM steel and W will also be described. |
