Aalo Atomics designs and builds factory-manufactured nuclear power plants, developing sodium-cooled extra modular reactor (XMR) technology for data centers, industry and cities. Founded in 2023, the company grew from two people to two hundred within three years while raising more than $300 million. Its flagship Aalo Pod is a 50-megawatt-electric modular reactor built around the Aalo-1 reactor design, packaged to scale up to gigawatt levels on a compact site footprint.
Aalo built the first new reactor facility at Idaho National Laboratory in fifty years, assembling its Critical Test Reactor in under four weeks and completing an NQA-1 certified factory within six months, all for under $100 million in spending. In 2026 the company achieved first criticality and began construction of its full-scale Aalo-X power plant.
