Startup targets datacenters with 3D-printed nuclear reactor module

US startup Ampera unveiled its first fully 3D-printed silicon carbide nuclear reactor module at an event in Palm Beach Gardens, Florida. The prototype features a spherical monolithic gyroid core designed to operate for up to thirty years without refueling while delivering fifteen or thirty megawatts of power. Founder Brian Matthews stated the subcritical thorium-based design prevents runaway reactions and aims to supply datacenters with emission-free energy starting around 2030 after regulatory approval.
