Profile
Oklo Inc. is a designer of advanced nuclear reactors based in Santa Clara, California. Founded in 2013 by Jacob and Caroline DeWitte, Oklo Inc. focuses on fast-fission power plants. OpenAI co-founder Sam Altman served as Chairman of the Board of Directors, but stepped down in April 2025 to "avoid a conflict of interest ahead of talks between his company and the nuclear start-up on an energy supply agreement." The company's name is derived from Oklo, a region in the country of Gabon, Africa where self-sustaining nuclear fission reactions occurred approximately 1.7 billion years ago. Oklo's business model is aimed at developing, building, and operating fast-fission power plants to sell power to customers, and its main product line for producing power is the Aurora powerhouse product line. The Aurora powerhouse is a design for a small power plant to generate 15-75 MWe of electrical power using a fast neutron reactor to produce heat. Around 20 fast reactors have been tested since the 1950s, with over 400 reactor-years of cumulative operating experience. Wikipedia
