Datacenters Line Up For 750MW of Oklo’s Nuclear-Waste-Powered Small Reactors
Datacenter operators are increasingly turning to small modular reactors (SMRs) like those developed by Oklo to meet growing energy demands. According to The Register, Oklo has secured commitments from two major datacenter providers for 750 MW of power, pending regulatory approvals. It brings the firm’s planned nuclear build-out to 2.1 gigawatts. From the report: Oklo’s designs are, from what we understand, inspired by the Experimental Breeder Reactor II (EBR-II) and utilize liquid-metal cooling. They are capable of producing between 15MW and 50MW of power, depending on the configuration. That means Oklo’s datacenter customers plan to deploy somewhere between 15 and 50 of the reactors to satisfy their thirst for electricity. However, they may be waiting a while.
According to Oklo’s website, the nuclear startup hopes to bring its first plant online before the end of the decade. Before that can happen, though, Oklo will need to obtain approval from the Nuclear Regulatory Commission — something for which it says it’s already submitted applications. In 2022, the watchdog rejected an Oklo plan to build a small atomic reactor in Idaho, citing “significant information gaps” on safety-related measures.
That said, Oklo has lately received support from US government agencies including the Department of Energy (DoE), which has awarded a site use permit, while Idaho National Laboratory — home of EBR-II — has provided fuel material to support the efforts. Speaking of fuel, Oklo’s designs may not suffer from the challenges other SMR startups, like Terrapower, have encountered. Oklo’s designs are intended to run on recycled nuclear waste products from traditional reactors. In fact, the startup is currently working with DoE national labs to develop new fuel recycling technologies. Oklo hopes to bring a commercial-scale recycling plan online by the early 2030s.
