AMPERA Unveils Industry-First 3D-Printed Nuclear Reactor Module

A crowd of over 100 officials and industry leaders gathered at AMPERA’s Palm Beach Gardens innovation center yesterday to witness the reveal of the world’s first full-scale, 3D-printed nuclear reactor module, a milestone that signals a shift toward mass-produced, factory-built energy systems.

The hardware, which integrates both the core and the pressure vessel, utilizes a spherical monolithic gyroid design crafted from silicon carbide. This architecture is engineered to operate for three decades without the need for refueling. By relying on TRISO thorium kernels, the company aims to move away from active safety systems, prioritizing inherent stability through design and physics. CEO Brian Matthews described the achievement as a critical step in accelerating the commercial availability of modular nuclear power.

Beyond its nuclear ambitions, the company is positioning itself to serve high-demand sectors including AI data centers, defense, and maritime industries. This strategy is supported by an Integrated Energy Architecture that shares two-thirds of its components with conventional gas-powered systems. With a new Australian subsidiary already secured to bolster thorium supplies, AMPERA is now moving to industrialize these units for near-term deployment.
