The company is working to commercialize its metal-fueled fast reactor technology through its Aurora powerhouse product line. Oklo said the powerhouses are designed to run on fresh, recycled or down-blended nuclear fuel. Initial designs target electrical output of 15 to 75 megawatts, with the potential to expand the line over time to higher-output configurations.
