#CHOP: Oklo’s Values

Atomic Alchemy, a wholly owned subsidiary of Oklo, is building scalable U.S. radioisotope production capabilities in facilities dedicated to producing essential isotopes for healthcare, industry, research, and defense. In May 2025, executive orders were issued directing the U.S. Department of Energy (DOE) to take a leading role in unleashing the American nuclear renaissance. Through these directives, DOE established the Reactor Pilot Program (RPP) to demonstrate at least three advanced reactors reaching criticality by July 4, 2026, or as soon as possible under the program. In August 2025, DOE selected Atomic Alchemy and awarded an RPP project for a pilot radioisotope production facility
