OpenAI-backed nuclear startup receives DOE approval on new project

Nuclear power startup Oklo has made new progress toward its goal of reshaping the energy industry by advancing small modular reactor technology. The company finalized an agreement during the week of Sept. 22 with the U.S. Department of Energy (DOE), allowing it to move forward with plans for its first commercial microreactor, expected to be located in Idaho.

“As the only advanced fission company with a DOE site use permit, along with substantial regulatory progress and a secured fuel supply, Oklo is uniquely positioned to deploy the first commercial advanced fission power plant in the U.S.,” the company said in a statement.

Microreactors, like the one Oklo plans to develop, are seen as a more efficient alternative to traditional nuclear power plants. They are designed to be smaller, making them quicker and cheaper to both build and operate, while providing constant energy, unlike other renewables.

Oklo’s chairman, Sam Altman — CEO of OpenAI, a major player in artificial intelligence — reflects a growing trend of tech companies supporting nuclear power.

With increasing electricity demands on the horizon, particularly from data centers and AI operations, tech giants such as Microsoft and Amazon are exploring nuclear energy as a dependable source to meet their needs.

Oklo must still obtain a permit from the Nuclear Regulatory Commission before construction on its project can begin. However, with the DOE agreement in place, the company is now able to start crucial groundwork, including geotechnical assessments, environmental surveys, and infrastructure planning at the proposed Idaho site. Oklo aims to break ground in 2026, with plans to have the microreactor operational by 2027.
