Nuclear startup Deep Fission plans to bury micro-reactors to power data centers

Back in the 1950s, the U.S. started detonating nuclear bombs underground to limit the fallout, both radioactive and sociopolitical, unleashed by aboveground testing. Hundreds of feet of rock formed a tidy barrier for the next 40 years as countries continued to bomb the subsurface. Now, a nuclear startup wants to bury a small reactor underground,

Sam Altman-backed nuclear startup Oklo lands massive data center power deal, with caveats

Nuclear startup Oklo has signed a massive deal with data center operator Switch, but caveats abound. The new agreement would see Oklo building enough small modular reactors (SMR) by 2044 to generate 12 gigawatts of electricity for Switch’s data centers, which today serve a wide range of companies, including Google, Nvidia, Tesla, Paypal, JP Morgan

Regulators deliver successive blows to Amazon and Meta’s nuclear power ambitions

Amazon, Meta, and Microsoft have placed big bets on nuclear power to secure electricity for their data centers as AI and cloud computing have sent power use surging.  But as Amazon and Meta discovered last week, those bets are far from a sure thing. A series of recent rulings from regulators dashed their hopes of
