Additive Nuclear Manufacturing

NX Atomics Uses Metal 3D Printing to Reduce SMR Production Costs

NX Atomics is advancing small modular reactor production by partnering with Sciaky to manufacture reactor components using industrial-scale metal 3D printing. By applying Electron Beam Additive Manufacturing (EBAM), the company aims to reduce production costs, shorten lead times, and simplify the fabrication of nuclear-qualified parts. The approach adapts manufacturing techniques already proven in aerospace, defense, and space industries, where additive manufacturing has moved from prototyping to large-scale production.

The development highlights a broader shift toward digitally enabled manufacturing in the energy sector. Traditional nuclear projects often face cost overruns and lengthy construction timelines due to complex supply chains and specialized components. Additive manufacturing offers a way to streamline production while increasing design flexibility and scalability. For reactor developers, this could improve project economics and accelerate deployment. As demand for clean baseload power grows, advanced manufacturing methods may become a key differentiator for companies seeking to commercialize next-generation nuclear technologies.
