The Nuclear Regulatory Commission has granted approval to TerraPower to begin construction of a reactor in Wyoming. The project is the first new US commercial nuclear reactor in about a decade, according to The New York Times. TerraPower was founded by Bill Gates, and it took years for the business to receive regulatory approval for this construction effort.

TerraPower is part of a push to create more efficient and less expensive nuclear facilities as an alternative power source, particularly as AI companies and data center construction places more demands on the US' current infrastructure. TerraPower's project involves tech it has dubbed Natrium in its planned reactor. Using this liquid sodium approach rather than a traditional light-water reactor is part of how the company aims to reduce costs and time frames.

Advocates see nuclear reactors as a way to generate power without the climate impact of coal or gas plants. Critics point to the safety risks as a severe downside to this approach, while others question whether the creation and disposal of nuclear waste counter the environmental gains. The Gates-backed operation still isn't coming in cheap. The proposed facility could cost at least $4 billion and still faces logistical challenges before coming online as planned in 2031.

Meta has announced three new agreements to purchase nuclear power for its AI infrastructure as well as the Prometheus supercluster, a 1-gigawatt data center being built in Ohio. The social media giant is partnering with power companies Vistra, TerraPower and Oklo to deliver an expected 6.6 gigawatts of generation to its projects by 2035.

The company's agreement with TerraPower will fund the development of two new reactors capable of delivering up to 690 megawatts of power as early as 2032. The deal also gives Meta rights to energy from six other reactors that could deliver an additional 2.1 gigawatts by 2035. All this power would come from TerraPower's "Natrium" reactors, which use sodium instead of water as a coolant.

A partnership with Oklo will bring 1.2 gigawatts of nuclear power online as early as 2030. Meta says the agreement opens the door to the construction of multiple Oklo reactors, which it claims will create thousands of construction and long-term operations jobs in Ohio. OpenAI CEO Sam Altman is one of Oklo's largest investors, and owns just over 4 percent of the company.

Meta’s agreement with Vistra focuses on keeping existing nuclear plants running longer and boosting their output. Through new 20-year deals, Meta will buy more than 2.1 gigawatts of electricity from some of Vistra’s existing plants in Ohio, while also backing added capacity at those sites, plus another in Pennsylvania. Vistra expects the added capacity, totaling 433 megawatts, to come online in the early 2030s.

Big tech is increasingly turning to nuclear to power its AI ambitions. Meta signed a 20-year agreement with Constellation Energy for nuclear power last year. Meanwhile Microsoft is famously reopening Three Mile Island and will be the plant’s sole customer as part of a 20-year deal.
