PALM BEACH GARDENS, FL, July 9, 2026 – AMPERA has finished its first full-scale 3D-printed nuclear reactor module, including the core and pressure vessel, for a subcritical, solid-state thorium nuclear reactor designed for factory-built power generation.
The company unveiled the first nuclear module unit at its innovation center. More than 100 people attended, including local officials, business leaders and employees.
“This next-generation nuclear core and pressure vessel sets the foundation for factory-built, mass-produced nuclear energy,” said Brian Matthews, founder and CEO of AMPERA. “The advanced technology and additive manufacturing used demonstrate a clear commercial path for new nuclear technology coming to market in an accelerated manner.”
AMPERA’s spherical monolithic gyroid core is 3D printed with silicon carbide. The design is intended to operate for up to 30 years without refueling.
The company’s nuclear energy systems use tri-structural isotropic (TRISO) thorium kernels as fuel. In June, AMPERA established an Australian subsidiary to secure thorium supply and support U.S. advanced nuclear fuel production.
AMPERA’s modular nuclear systems use core design and physics characteristics to reduce reliance on active systems and operator intervention. The systems are expected to provide up to 30 MWe of power, with larger configurations planned.
Last week, AMPERA announced its “Power Now. Nuclear Next.” strategy and Integrated Energy Architecture. The approach covers waste heat recovery and conventional-fueled power generation. The modular, gas-powered systems use AMPERA’s supercritical carbon dioxide technology. Those systems are two-thirds common with the nuclear configuration.
“Our reactors are built for the markets that need power the most: AI data centers, defense, industrial and maritime,” Matthews said. “We expect to be the first company to industrialize factory-built nuclear power with near-term deployment timelines.”
