In a major advancement for nuclear construction, the Depart<\/a>ment of Energy\u2019s Manufacturing Demonstration Facility (MDF) at Oak Ridge National Laboratory (ORNL), in part<\/a>nership with Kairos Power and Barnard Construction, has developed and validated large-scale 3D-printed polymer composite forms. These are used to cast complex concrete structures for Kairos Power\u2019s Hermes Low-Power Demonstration Reactor, now under construction at their Oak Ridge campus.<\/p>\n

These 10-by-10-foot forms, stacked three high, were displayed at the East Tennessee Economic Council\u2019s Nuclear Opportunities Workshop in July. They serve as precursors for forms to be used in the Hermes reactor, enabling \u201ccast-in-place\u201d construction of intricate geometries in days instead of weeks. Unlike traditional wood or steel forms, these 3D printed molds significantly reduce time and cost.<\/p>\n

\u201cAt ORNL, we\u2019re showing that the future of nuclear construction doesn\u2019t have to look like the past,\u201d said Ryan Dehoff, Director of the MDF. ORNL\u2019s decade of \u201cmoonshots,\u201d from 3D printing<\/a> cars and homes to real-time digital part<\/a> qualification, is now modernizing nuclear energy<\/a>.<\/p>\n

Kairos Power co-founder and CTO Edward Blandford highlighted the MDF\u2019s speed and creativity: \u201cThey move fast, they think creatively, and they\u2019ve demonstrated that they can deliver transformative results when conventional manufacturing would fall short.\u201d Referred to MDF by a commercial part<\/a>ner, Blandford said, \u201cIt\u2019s not often we get advice from industry to call the national lab because they move quickly.\u201d<\/p>\n

\u201cThis project fits squarely into our iterative development approach,\u201d Blandford added, emphasizing early testing to reduce risk and streamline regulatory engagement.<\/p>\n

The Janus column form is part<\/a> of Kairos Power\u2019s bioshield design \u2013 a concrete structure shielding workers from reactor radiation. Part<\/a>ners, including Airtech, TruDesign, Additive Engineering Solutions, and Haddy, established a new additive-enabled supply chain. Barnard adapted the forms, giving real-time feedback and implementing design changes.<\/p>\n<\/p>\n

ORNL\u2019s Ahmed (Arabi) Hassen explained that the challenge was ensuring the molds maintained structural integrity under high concrete pressure, requiring cutting-edge design and print strategies.<\/p>\n

Funded by DOE\u2019s Advanced Materials and Manufacturing Technologies Office, the project is part<\/a> of the SM2ART Moonshot Project, led by MDF and the University of Maine. It combines advanced materials science, AI, and large-format 3D printing<\/a> to modernize nuclear construction. Over the next 18 months, the project will scale up to full-size shielding forms using smart<\/a> manufacturing and low-cost, timber-based biocomposites.<\/p>\n
