The US Department of Energy is providing $17.5 billion in conditional loan guarantees to support deployment of AP1000 nuclear reactors by Westinghouse and Cameco-backed projects. This represents a major federal commitment to expanding nuclear capacity in the United States.

The loan guarantees underscore the role nuclear power is playing as a potential solution to the enormous electricity demands of AI data centers. As computational infrastructure providers increasingly seek reliable, carbon-free baseload power to support AI workloads, nuclear reactor deployment has become a strategic priority for the federal government. The AP1000 is a modern reactor design that can provide substantial electricity generation capacity.

The backing of Cameco and Westinghouse—major players in nuclear fuel and reactor manufacturing respectively—signals coordination across the nuclear supply chain. These conditional loan guarantees are intended to de-risk large-scale reactor projects and accelerate deployment timelines, positioning nuclear as a critical infrastructure component for powering the next generation of AI computing facilities.
