US: Oak Ridge National Laboratory has launched new composite forms for 3D-printed polymer concrete for Kairos Power’s Hermes low-power demonstration reactor in Oak Ridge, Tennessee. The forms reduce construction times ‘from weeks to days’ and reduce costs, according to the developer. Also partnering on the project were Additive Engineering Solutions, tooling materials producer Airtech, Barnard Construction, 3D printers supplier Haddy, coatings producer TruDesign and the University of Maine.
The Hermes reactor is part of the US Department of Energy’s SM2ART Moonshot Project to install nuclear power plants with scalable technologies on the US grid.
