In the last several weeks of 2025 alone, nuclear startups raised $1.1 billion, largely on investor optimism that smaller nuclear reactors will succeed where the broader industry has recently stumbled. Traditional nuclear reactors are massive pieces of infrastructure. The newest reactors built in the U.S. - Vogtle 3 and 4 in Georgia - contain tens of thousands of tons of concrete, are powered by fuel assemblies 14 feet tall, and generate over 1 gigawatt of electricity each.
