Startup unveils 3D-printed nuclear reactor module to power AI data centers

Ampera, a nuclear technology startup, has unveiled its first full-scale 3D-printed nuclear reactor module designed to power AI data centers. This module, described as the world's first subcritical, so... Read original →

Ampera’s 3D-printed thorium-based subcritical reactor isn’t just a nuclear novelty—it’s a direct response to AI data centers’ unsustainable power demands. Technologically, its solid-state core and supercritical CO₂ Brayton cycle will force upgrades across thermal management, high-temperature materials, and wide-bandgap semiconductors like SiC/GaN. Regulatory hurdles remain steep: despite thorium’s lower proliferation risk, SMR licensing lags outside the U.S. and Canada, making deployment in regions like Taiwan, China or Hong Kong, China unlikely soon. Strategically, NVIDIA’s implicit endorsement via energy partnerships pressures rivals—Oklo and Bloom Energy will likely fast-track competing micro-reactor offerings. Within 18 months, a successful grid connection by Ampera could catalyze a paradigm shift: AI facilities may abandon traditional ‘grid-plus-batteries’ models for on-site, zero-carbon baseload power, fundamentally resetting the economics of compute.
