The need for emissions-free power generation, along with the ability to provide more power when and where it’s needed, is driving research and development of smaller nuclear reactors. Energy industry

Oklo has moved to acquire Atomic Alchemy, a U.S. firm specializing in high-value radioisotopes, in a $25 million all-stock transaction. The acquisition will add radioisotope production capabilities to Oklo’s advanced reactor and fuel recycling operations, creating a new revenue stream and strengthening the resilience of the isotope supply chain, the company said. Radioisotopes, unstable atoms […]

The decarbonization of power generation is fostering research and development of new energy technologies, and some companies are reimagining what’s possible when it comes to power plant design. That includes pairing nuclear power with solar power, in a system that could repurpose a brownfield site—for example, a closed or soon-to-retire thermal power plant with transmission […]

Siemens Energy may be poised to become a crucial equipment and consulting partner for Oklo’s Aurora powerhouse, a liquid metal-cooled fast nuclear reactor. A memorandum of understanding (MOU) Oklo unveiled on Dec. 19 designates Siemens Energy to become Oklo’s potentially preferred supplier for the rotating equipment in the conventional island of the Aurora powerhouse, including […]

The U.S. Air Force’s first nuclear microreactor planned for Eielson Air Force Base in Alaska under a federal nuclear microreactor pilot program will be an Oklo liquid metal-cooled fast reactor. The Defense of Logistics Agency (DLA), acting on behalf of the Department of Air Force (DAF), on Aug. 31 issued a Notice of Intent to Award […]

Centrus, a firm poised to demonstrate high-assay, low-enriched uranium (HALEU) production, will partner with microreactor technology developer Oklo on several pioneering steps to build out the HALEU front-end supply chain, including pivotal commercial deconversion capabilities.
