Small modular reactor (SMR) and nuclear fuel recycling company Oklo has partnered with two undisclosed data center providers to deliver up to 750MW of power.

The Letters of Intent (LoIs) expand Oklo’s customer pipeline to approximately 2,100MW. This follows previous agreements with Equinix and Prometheus for 500MW and 100MW of nuclear power, respectively.

Oklo offers SMR fast fission units ranging from 15MW to 50MW that can be deployed in phases. The company claims this approach aims to minimize project risk and reduce financing costs.

DCD reached out to Oklo for further information.

Last month, Oklo received approval from the US Department of Energy for its conceptual safety design report on its proposed Aurora Fuel Fabrication Facility at Idaho National Laboratory (INL) in the US.

Oklo aims to commission the Aurora reactor at INL in 2027, making it the first advanced nuclear reactor completed in the US.

Oklo has secured backing from OpenAI CEO Sam Altman, who has been chairman of its board of directors since October 2015.

However, Oklo has also suffered several setbacks. Late last year, the US Air Force rescinded a $100m award for one of its microreactors, and it has yet to receive approval from the Nuclear Regulatory Commission for its designs.

Oklo's announcement is the latest in a long line of agreements signed in 2024 between the data center and SMR sectors.

Last month, AWS signed three agreements with Energy Northwest, X-Energy and Dominion Virginia to support the deployment of over 600MW of power across Washington and Virginia.

Before this, Google signed a corporate agreement to purchase nuclear energy from multiple SMRs from Karios Power, with an expected deployment date in 2030.
