University Of Maine Prints Reactor Shielding Components
University of Maine researchers at the Advanced Structures and Composites Center used the world's largest polymer 3D printer to produce precision sinusoidal concrete form liners for Kairos Power's 35-megawatt Hermes reactor, constructed in Oak Ridge, Tennessee. The 27-foot-tall, three-foot-thick wall sections were printed, machined to millimeter tolerances, and integrated with digital assurance via the Material Process Property Warehouse to reduce cost and accelerate construction.
Key Points
- 1Printed specialized sinusoidal form liners for Kairos Power's 35 MW Hermes reactor, achieving millimeter precision.
- 2Reduced cost and increased speed compared with conventional methods, enabling commercial construction timelines.
- 3Demonstrates scalable university-industry manufacturing and digital assurance for certified large-scale additive components.
Scoring Rationale
Strong demonstration with official DOE and industry backing, but limited novelty beyond a single project and narrow industrial scope.
