Lawmakers across the aisle are looking to galvanize projects that would help tech companies power their bold artificial-intelligence ambitions.

At a hearing last Thursday of the energy subcommittee of the House Committee on Science, Space and Technology, representatives from both parties pressed the nuclear industry on how they could help it boost growth.

“This isn’t just good energy policy, it’s good economic policy, creating well-paying jobs and generating millions in tax revenue that would otherwise be lost,” said Rep. Brian Babin (R., Texas) at the hearing.

“We must intentionally build a more reliable and sustainable energy supply, and we should be using any environmentally benign resources—including nuclear—available to do so at the lowest cost possible,” said Rep. Deborah Ross (D., N.C.).

Late last year, Microsoft announced a deal with Constellation Energy to reopen the Three Mile Island plant in Pennsylvania, site of the nation’s worst nuclear accident. And early this month, Constellation signed a two-decade deal with Meta Platforms to fuel its AI needs through a nuclear plant—the Clinton Clean Energy Center—in Clinton, Ill.

In May, the nuclear and tech industries secured a boon: President Trump signed a flurry of executive orders to buoy the nuclear industry by speeding up the time it takes to secure project licenses and use federal lands for reactors for the military or AI data centers.

Speaking at the hearing Thursday, Kathleen Barrón, executive vice president and chief strategy and growth officer at Constellation, pushed in particular to restart some previously closed reactors.

She proposed “extending the operating life of existing reactors, by increasing the output of the existing fleet of plants, and by restarting previously closed reactors that are capable of resuming operation.”

She continued: “The most logical place in our view to think about siting new nuclear plants is at sites that are already hosting nuclear reactors” as these locations have already met environmental and safety standards and have the surrounding infrastructure to host the reactors.

Regulations for technologies with “decades of proven safety” need to be updated, Pat Schweiger, chief technology officer at nuclear-tech startup Oklo, testified at the hearing. Oklo late last year sealed a deal to provide nuclear power to Switch, a provider of data centers. No mention was made at the hearing of the Three Mile Island and Chernobyl accidents, which set nuclear power back decades.
