Today, global technology powerhouse Siemens announced that it has completed the first successful commercial installation, and continuing safe operation, of a 3D printed part inside a nuclear power plant. This milestone is a nuclear industry breakthrough: the nuclear sector obviously has incredibly exacting reliability and safety requirements, so the fact that a 3D printed part made it through these requirements is a big accomplishment. The 3D printed replacement part was produced for a plant that's been in operation for over thirty years in Slovenia, the Krško Nuclear Power Plant (NEK). The part Siemens worked with is a metallic impeller, with a diameter of 108 mm, for a fire protection pump that operates in a constant rotation and provides pressure for the plant's fire protection system.
