“This is the start,” Wright said on a call with reporters. “We’re going to move with the players that are ready to stand up and move quickly. Once that supply chain is up and running, do we think there will be dozens of these built going forward? I’d be very surprised if there were not.”

Most U.S. nuclear power plants were built between 1970 and 1990. have been built from scratch in the United States in recent decades. Those two reactors, at Georgia Power Co.’s Plant Vogtle, were completed years late and billions of dollars over budget. The 10 new reactors will use the same design, Westinghouse’s AP1000.

Wright said the Plant Vogtle project struggled because of bad planning, supply chain problems and the COVID-19 pandemic. But, he said, the reactor design is “robust and sound.”

“By building in volume and at multiple locations, we think we will create and stand up a large supply chain and build a lot of construction expertise,” Wright said. “We expect the timing and cost of these plants to well outperform what was done on Vogtle.”

Seven utilities and energy companies signed letters of intent that identified sites, the Energy Department said. The agency plans to pick five, which would host two reactors at each site. The federal financing would be used to purchase nuclear components with long lead times, and are not construction loans.

The department declined to name the utilities involved or the states they are in, calling it premature until the selections are made. It did not give a timeline for making those selections.

President Donald Trump set a goal of quadrupling domestic production of nuclear power within the next 25 years, and he has to speed development. The administration is working to advance new nuclear technologies, .

Dan Sumner, president and chief executive officer of Westinghouse, said industrialized nuclear power needs to be built at fleet scale, in order for the United States to lead in artificial intelligence, advanced manufacturing and the industries that will define the next century.

Critics of building more nuclear reactors say they’re too expensive and riskier than other low-carbon energy sources.

in 2024, a share that could nearly triple by 2028, according to government estimates. Some analysts predict nationwide electricity use to rise as much as 20% in the next decade, with data centers a big reason.

The Energy Department said the loans could speed up the development of these 10 reactors by up to three years and lower construction costs. Its goal is for all 10 to be under construction by 2030, to start providing power in the mid-2030s.

The utilities and Westinghouse will be expected to contribute up to $5 billion in equity in total across the five, two-reactors projects. Wright said his department provides up to $17.5 billion in loans, or $3.5 billion per project, in debt to pair with the equity. He said it's “very, very low risk to the American taxpayers.”
