Ampera has unveiled a 3D-printed nuclear reactor module designed to power AI data centers. This subcritical, solid-state reactor, constructed using additive manufacturing, promises safer operations and quicker production for mass deployment.
Ampera, a startup focused on nuclear technology, has introduced its first full-scale 3D-printed nuclear reactor module. The company claims it to be the world's first subcritical, solid-state thorium nuclear reactor, targeting applications in AI data centers.
The reactor is designed to be subcritical, meaning it requires an external source to initiate the fission process, which enhances safety by minimizing the risk of a runaway reaction. Its solid-state core lacks moving parts, simplifying maintenance and operation.
Ampera highlights the factory-built nature of the module, indicating that it can be produced quickly in a production line. This approach aims to facilitate mass production and reduce transportation costs, making the technology scalable for broader use.
The reactor utilizes thorium as its primary fuel, which is noted for being more abundant and cheaper than uranium. While capable of being used in weaponry, thorium presents greater challenges in terms of proliferation, as stated by the World Nuclear Association.
Despite Ampera's significant announcement, the startup has yet to activate the reactor for electricity production. This contrasts with Valar Atomics, which has successfully turned on its Ward 250 nuclear microreactor to power a data center application, indicating a competitive market in nuclear microreactor technology.
