Valar Atomics raises $1 billion Series B to mass produce small nuclear reactors for the AI industry

Valar Atomics Inc. said today it has raised a bumper $1 billion Series B funding round to help it move from building prototype small nuclear reactors to manufacturing them at scale on a production line. Today's round was led by Sequoia Capital and saw participation from nine other venture capital firms, including Valor Equity Partners and Conviction. In addition, Valar said it has also secured a separate $200 million credit facility from Erebor, J.P. Morgan, Crescent Cove and Hercules Capital. Valar Atomics founder and Chief Executive Isaiah Taylor said the investment will help the company to change what it does, rather than what it designs. It can now shift from demonstrating the operability of an integrated reactor system to producing fleets of them en masse. The startup intends to build hundreds of small modular reactors, known as SMRs, which are basically miniaturized power plants, on production lines, similar to how cars are manufactured. In June, Valar Atomics partnered with Nvidia Corp. to demonstrate the effectiveness of its small Ward-250 test reactor, which was installed in a data center and used to power Blackwell graphics processing unit running artificial intelligence workloads. Following that demonstration, Valar announced an expanded partnership with Nvidia to build a complete 30-megawatt nuclear-powered AI facility in Utah.
