X-energy Secures Approval for Four New Modular Reactors

X-energy's First Steps in Nuclear Innovation

Nuclear technology startup X-energy has announced a significant milestone: federal approval to construct its first four commercial small modular reactors (SMRs). This decision comes from the Nuclear Regulatory Commission (NRC) and paves the way for groundbreaking advancements in the nuclear power sector.

Details of the Approval

The approval allows X-energy to build their Xe-100 reactors, which are planned to be installed at a Dow Chemical facility in Texas. Each of these reactors is designed to generate 80 megawatts of electricity and produce 200 megawatts of thermal energy. Notably, this represents the first clearance for an advanced nuclear reactor to be integrated into an industrial setting in the U.S.

The Promise of Small Modular Reactors

SMRs like those developed by X-energy are seen as a key component for revitalizing the U.S. nuclear industry. With a smaller footprint compared to traditional reactors, supporters believe that SMRs could lead to quicker construction timelines and reduced overall costs. However, it's important to note that none of these reactors are currently operational in the United States, and X-energy anticipates that their new reactors will not be online until the early 2030s.

Safety Concerns and Industry Skepticism

X-energy's unique reactor design utilizes helium gas to flow over uranium-based fuel pellets, which the company claims enhances safety compared to existing reactors. Nonetheless, the Union of Concerned Scientists has expressed reservations regarding safety and the hastiness with which X-energy was granted its construction permit.

“The NRC only accomplished this feat by pushing consideration of critical safety questions to a later date—issues the NRC should’ve fully resolved before green lighting construction,” stated Edwin Lyman, director of nuclear power safety for the organization.

Investor Interest and Future Aspirations

The nuclear sector has garnered significant attention from major tech players, especially hyperscalers and data center developers, hungry for reliable energy sources. A noteworthy partnership has emerged with Amazon’s Climate Pledge Fund, which spearheaded X-energy’s $500 million Series C-1 funding round, alongside a commitment to secure 5 gigawatts of capacity from X-energy's future operations.

Earlier in the year, X-energy experienced a surge of financial support with a successful initial public offering (IPO) that raised $1 billion. However, since that peak, investor enthusiasm seems to have cooled.

The Path Ahead for X-energy

Nuclear power plants are notoriously costly and time-consuming to develop, which adds an element of uncertainty to X-energy's plans. Although the company aspires to minimize both expense and construction time, the pricing of the first reactors may still be on the high side.

The recent construction permit approval has provided a minor boost to X-energy, enabling the company to recover some losses from the previous week. Despite this improvement, the stock is currently trading at below half of its original offering price.
