Abstract Scope Long-term safe storage of used fuel is an important aspect of nuclear energy systems. The results of an initial study include the development of cold spray process for the deposition of 304L stainless steel powder for field mitigation of potential chloride-induced stress corrosion cracking (CISCC) in used fuel dry cask storage canisters. As expected the welded regions of these austenitic stainless canisters may be more prone to CISCC due to the presence of tensile stresses and thermally-induced microstructures during fusion welding. This experimental study evaluated a feasibility of cold spray process for simulated microstructural and surface conditions that may exist in the weld regions of actual stainless-steel canisters. Thickness, microstructure, and phases in the cold spray deposits and substrate-deposit interfaces were characterized by scanning electron microscopy, transmission electron microscopy, and x-ray diffraction. Adhesion strength between the stainless-steel deposit and the substrate were measured for various cold spray parameter was evaluated.
