About Oklo
Electric Services, SIC 4911
Oklo Inc. develops fast fission nuclear power plants, known as Aurora powerhouses, designed to generate electricity and heat using fresh, recycled, or down-blended nuclear fuel. The company focuses on a build, own, and operate model to sell energy directly through power purchase agreements rather than selling reactor designs.

Through its subsidiary Atomic Alchemy, the company also focuses on radioisotope production for medical, energy, industrial, defense, and artificial intelligence applications. Oklo targets customers across various sectors, including data centers, industrial operations, utilities, military bases, remote communities, and commercial campuses.
Oklo conducts operations primarily in the United States, with planned and active project sites including the Idaho National Laboratory in Idaho, Pike County in southern Ohio, and Oak Ridge, Tennessee.
