With $1 billion federal funding X-energy advances small nuclear reactor production

The Amazon-backed firm is aiming to build up to 144 of its novel Xe-100 reactors as the U.S. government seeks to revitalize an industry beset by rising costs.

The Department of Energy’s new funding nearly doubles previous federal support for X-energy’s project at a Dow Chemical site, aiming to jumpstart commercial advanced nuclear power in the early 2030s. This marks a significant structural push to revitalize a stagnant American nuclear industry amid growing energy and carbon reduction demands.

X-energy is developing four 80-megawatt Xe-100 reactors at Seadrift, Texas, with environmental approval granted in May but awaiting Nuclear Regulatory Commission construction licensing expected by early 2027. The DOE has reimbursed X-energy $546 million under its Advanced Reactor Demonstration Program, contributing to a total federal commitment exceeding $2 billion. The project’s estimated cost ranges from $4.75 billion to $5.75 billion, with Dow Chemical’s facility targeting substantial emissions reductions. X-energy also plans to open its first commercial fuel fabrication plant near Oak Ridge National Laboratory by mid-2028.

The critical next step is the NRC’s anticipated construction license decision in early 2027, followed by Dow’s final investment decision at the earliest in 2028.

While Montana is not directly involved, the state’s energy sector might find lessons in the challenges of integrating costly nuclear technologies alongside cheaper renewables. Montana’s vast geography and legacy energy infrastructure could shape how emerging advanced reactors might fit into future regional energy strategies, especially as federal support influences national industry trends.

With federal funding windfall, X-energy advances small nuclear reactor
