Startup unveils 3D-printed nuclear reactor module to power AI data centers - touted as ‘the world’s first subcritical
Nuclear tech startup Ampera has unveiled its first full-scale, 3D-printed nuclear reactor module, which it describes as the world's first subcritical
Key takeaways
- Ampera has revealed the world's first subcritical, solid-state, factory-built thorium nuclear reactor module.
- The advanced technology and additive manufacturing demonstrate a clear commercial path for new nuclear technology.
Nuclear tech startup Ampera has unveiled its first full-scale, 3D-printed nuclear reactor module, which it describes as the world's first subcritical, solid-state, factory-built thorium nuclear reactor. Designed to power AI data centers, defense, industrial, and maritime applications, the module is part of an Integrated Energy Architecture targeting a 30MWe output using a closed-loop, supercritical CO2 Brayton-cycle turbine. While Ampera has revealed the finished module, it has not yet demonstrated active power generation or provided a specific deployment timeline.
In their words
“This next-generation nuclear core and pressure vessel sets the foundation for factory-built, mass-produced nuclear energy”
“Our reactors are built for the markets that need power the most: AI data centers, defense, industrial and maritime”
By the numbers
- 30MWe
- Target power output for Ampera's complete system
- 30MW
- Capacity of the data center Valar Atomics is partnering with Nvidia to power
Why this matters
-
Ampera expects to be the first company to industrialize factory-built nuclear power with near-term deployment timelines.
