Apollo Atomics has raised $31 million in seed funding to turn decades-old nuclear reactor technology into something the industry has struggled to deliver: a reactor that can be built in a factory, shipped by truck, and deployed in less than […] The post MIT spinoff Apollo Atomics raises $31M to build factory-made nuclear reactors for AI data centers first appeared on Tech Startups.

Exclusive: Apollo Atomics wants to make nuclear power cheaper by shrinking an overlooked part

Y Combinator alumnus Apollo Atomics is shrinking a key nuclear reactor part, which promises to slash the cost of electricity below natural gas.

MIT spinoff Apollo Atomics grabs $31M seed to shrink nuclear reactors by 40x

Apollo Atomics has received $31 million in seed funding, with FCVC leading, to develop nuclear reactors that can be built in factories. Its new steam generator design makes the reactor approximately 40 times smaller. The company’s advantage might stem from the regulatory expertise of one of its co-founders, rather than merely from technical innovation. Apollo Atomics, a nuclear startup founded in 2025 by Assil Halimi and Drew Walker, raised $31 …
