Trump administration to fund $17.5B in low-interest loans for nuclear reactors

The US Department of Energy just made the biggest bet on nuclear power the country has seen in decades. The Trump administration announced $17.5 billion in conditional low-interest loans to fund the construction of up to 10 nuclear reactors, a move designed to jumpstart an industry that has spent years stuck in bureaucratic quicksand and cost overruns.

The loans, announced on June 23, will flow through the DOE’s Energy Department Finance program to cover long-lead-time components for Westinghouse AP1000 reactors. Think pressure vessels, steam generators, and coolant pumps, the kind of massive, custom-built hardware that takes years to manufacture and has historically been a bottleneck for getting new plants online.

What the plan actually looks like

The initiative targets five separate projects that would collectively house 10 AP1000 reactors. The explicit goal is to shorten construction timelines by up to three years. At least seven utilities and energy companies have already submitted letters of intent to participate. The program focuses specifically on bolstering domestic manufacturing capacity for large commercial reactors, a capability the US has let atrophy over the past several decades.

This initiative aligns with a broader executive order Trump signed in May 2025, which established an ambitious target of growing US nuclear capacity to 400 GW by 2050. To put that number in perspective, the US currently operates roughly 95 GW of nuclear capacity across its existing fleet. Getting to 400 GW would mean more than quadrupling the country’s nuclear footprint in about 25 years.

Why nuclear, why now

Energy demand in the US is surging, driven largely by the explosive growth of data centers powering AI workloads. Tech giants like Microsoft, Google, and Amazon have all signaled willingness to sign long-term power purchase agreements with nuclear providers, creating a demand signal that didn’t exist five years ago.

The $17.5 billion loan commitment is the federal government’s attempt to break the chicken-and-egg problem of nuclear manufacturing: no one invests in manufacturing capacity without orders, and no one places orders without confidence in the supply chain. By guaranteeing financing for the components, the DOE is essentially de-risking the earliest and most capital-intensive phase of reactor construction.

What this means for investors

Westinghouse, the manufacturer behind the AP1000 design, stands to benefit most directly. The company was acquired by Cameco Corporation and Brookfield Renewable Partners in 2023, and a pipeline of 10 new reactor orders would represent a transformational volume of business. Uranium producers are another obvious beneficiary, since more reactors mean more fuel demand over lifespans measured in decades, not years.

But investors should also weigh the risks carefully. These are conditional loans, meaning the projects still need to clear regulatory and financial hurdles before the money actually flows. And the history of US nuclear construction includes the Vogtle nuclear expansion in Georgia, the only new reactor project completed in the US in recent memory, which came in years behind schedule and billions over budget.
