Regulatory approvals remain critical to the commercial deployment of advanced nuclear technologies. Oklo Inc. OKLO is working with the U.S. Department of Energy (“DOE”) and Nuclear Regulatory Commission (“NRC”) to advance its reactor, nuclear fuel and isotope businesses. Rather than following a uniform licensing process, OKLO is pursuing regulatory pathways tailored to individual facilities. This approach allows the company to gain operating experience through DOE-authorized projects and apply those lessons to future NRC-licensed commercial developments, supporting more efficient and repeatable reactor deployment.
OKLO has achieved important regulatory milestones at its Aurora-INL project, including DOE approval of the Preliminary Documented Safety Analysis. This clearance enables further progress on final design, construction and procurement activities. The remaining steps include approval of the Documented Safety Analysis, completion of readiness reviews and startup authorization. Meanwhile, OKLO's Groves Isotope Test Reactor achieved first criticality in August 2026 under DOE authorization. This milestone demonstrates the company's ability to navigate regulatory requirements and provides practical experience that can support subsequent nuclear projects.
Beyond Aurora-INL, OKLO is preparing for NRC pre-application activities at its proposed 1.2-gigawatt Ohio power campus. The company is also advancing Groves-2 Forge under DOE's Nuclear Energy Launch Pad initiative, with plans to pursue NRC licenses for commercial isotope production. The facility will initially focus on lutetium-177, used in cancer treatments. By combining regulatory engagement with experience gained from operating facilities, OKLO aims to streamline future approvals, strengthen execution capabilities and establish a scalable framework for expanding its nuclear technology portfolio.
How Nuclear Peers Are Managing Licensing and Fuel Risk
NuScale Power SMR benefits from established regulatory approvals and conventional nuclear fuel availability. The company secured NRC standard design approvals in 2020 and 2025, alongside design certification in 2023. NuScale Power uses commercially available low-enriched uranium, reducing dependence on scarce advanced reactor fuels. Its mature supplier network and ongoing manufacturing activities further strengthen NuScale Power's readiness for commercial deployment.
NANO NuclearEnergy NNE is advancing its KRONOS MMR project through NRC's construction permit review process. The regulator targets completing its final safety evaluation in September 2027. Meanwhile, NANO Nuclear Energy has agreed to acquire NRC-licensed fuel processing assets in New Mexico, subject to closing conditions. This proposed acquisition offers NANO Nuclear Energy opportunities to strengthen domestic fuel capabilities and streamline future licensing activities.
