NRC Approves X-energy's First Small Modular Nuclear Reactors

· Confirmed

Technology Desk

In Short: The Nuclear Regulatory Commission (NRC) has given X-energy the green light to construct its first small modular nuclear reactors, a significant step toward reviving the United States' high-temperature gas-cooled reactor efforts.

According to Canary Media, the NRC approved the environmental review for X-energy's first project, which will see the company build four of its 80-megawatt Xe-100 reactors at Dow’s UCC Seadrift Operations in Texas.

TechCrunch reported that X-energy announced Monday it had received the go-ahead from federal officials to build its first four commercial reactors, each capable of generating 80 megawatts of electricity and 200 megawatts of heat.

X-energy said the architecture supports siting close to industrial facilities and envisions an emergency planning zone of 400 meters, reflecting the company's design assumptions.

In addition to the Texas project, X-energy is also developing a larger, 330-megawatt project at Colorado’s Fort St. Vrain nuclear plant.

The deal supports more than $3 billion in infrastructure investment at the Calvert Cliffs nuclear plant in Maryland, including upgrades adding 190 megawatts of generating capacity between 2030 and 2032.

X-energy's April initial public offering raised $1 billion, riding a wave of excitement for small modular nuclear reactors.

X-energy's plans align with broader trends in the nuclear industry, such as Constellation Energy's $4.3 billion investment to refurbish and improve 11 reactors at six plants in Illinois, Pennsylvania, and New Jersey.

The NRC's approval marks a significant milestone for X-energy, paving the way for the company to build its first commercial reactors and potentially reshape the U.S. Nuclear landscape.

What this adds

The NRC's approval of X-energy's environmental review and construction permit represents a major step forward for the company's small modular reactor projects. This approval is consistent with prior WarpBeat coverage, which noted the NRC's initial green light for X-energy's reactors.
