Oklo, Inc. is a California-based energy technology company specializing in the design and development of advanced nuclear microreactors. Headquartered in Fremont, the firm focuses on small modular reactor (SMR) technology that leverages fast-neutron fission and liquid-metal cooling to deliver carbon-free power. Oklo’s core objective is to bring compact, factory-built reactors online within a decade, offering a low-footprint alternative to traditional large nuclear plants.

The company’s flagship product, the Aurora microreactor, is a 1.5-megawatt electric (MWe) fast reactor cooled by a sodium alloy. Oklo submitted a combined license application to the U.S. Nuclear Regulatory Commission in 2021, marking a critical step toward regulatory approval. The design emphasizes simplicity and modular construction, with factory fabrication of key components to reduce on-site assembly time and construction costs.

Oklo targets a range of off-grid and grid-support applications, including mining operations, remote communities, and industrial sites seeking reliable, low-carbon energy. By pairing microreactors with renewable generation and energy storage, the company aims to enhance grid resilience and reduce dependence on fossil fuels. Partnerships with the U.S. Department of Energy and Idaho National Laboratory support Oklo’s research, licensing, and demonstration efforts.

Founded in 2013 by nuclear engineers Caroline Cochran and Jacob DeWitte, Oklo is led by Cochran as Chief Executive Officer and DeWitte as President and Chief Financial Officer. The leadership team brings experience in reactor design, regulatory strategy, and commercial project development, positioning the company to address emerging energy demands and help decarbonize hard-to-abate sectors.
