TVEL to 3D Print End Fittings of Fuel Assemblies
back to contents“We plan to use additive manufacturing solutions in the nuclear industry to produce components of fuel assemblies. They will be primarily end fittings, such as heads, shanks, spacer grids, and debris filters, which are very difficult to produce with conventional methods. By contrast, 3D printing will create components of unique design,” said Leonid Karpyuk, Director of the Institute. The project will tap to the Institute’s existing competencies in this field, particularly expertise in creating additive manufacturing powders by means of centrifugal atomization. Powders produced at the Institute meet all necessary requirements, namely a spherical shape, size (10–80 µm), and chemical uniformity of powder grains with no oxidation films, other surface contamination or porosity, and outperform many of similar foreign products.
