The Nuclear Regulatory Commission (NRC) approved the key environmental review for X-energy's planned high-temperature gas-cooled reactor facility in Texas, allowing the company to move closer to securing construction permits. This marks a significant step for the Amazon-backed startup, which aims to revive the United States' efforts in advanced gas-cooled reactor technology.
The environmental impact statement concluded there were no showstoppers that would preclude licensing the plant, though specific emissions reductions from the project were not detailed by the NRC in the review. Advanced reactors like X-energy's are designed to run at higher temperatures than traditional water-cooled models, potentially improving efficiency and enabling new industrial applications.
The project represents a major investment in next-generation nuclear power, though the exact funding amounts were not specified in the NRC filing. X-energy's technology could create hundreds of construction and operational jobs in Texas, aligning with broader U.S. goals to deploy advanced nuclear reactors by the early 2030s.
This approval comes amid a global push to expand nuclear capacity as a low-carbon energy source, with the U.S. aiming to triple nuclear output by 2050 under international climate commitments. The Texas location places the project in a state with deregulated energy markets and existing nuclear expertise.
Critics argue that high-temperature gas-cooled reactors remain unproven at commercial scale and face significant cost and timeline risks compared with established light-water designs. Some environmental groups also question whether nuclear power deserves subsidies that could otherwise support renewable energy deployment.
