(NYSE: OKLO) (\u201cOklo\u201d or \u201cthe Company\u201d), an advanced nuclear technology company, today announced the U.S. Department of Energy (DOE) has cleared the final operations hold point for the Groves Isotope Test Reactor (Groves-1), allowing the facility to advance into its research, testing, and training phase. With the facility cleared for unrestricted operations, Oklo will test its capabilities relevant to future isotope reactors and Oklo\u2019s fast fission reactors, the Aurora powerhouse.<\/p>\n<p id=\"news-body-cta\">This press release features multimedia.

(Image: Oklo)\" \/><\/p>\n<p style=\"font-size:85%\">Groves Isotope Test Reactor. (Image: Oklo)<\/p>\n<\/div>\n<p>\nGroves-1, under DOE authorization through the DOE Reactor Pilot Program (RPP), reached first criticality at low power less than a year after groundbreaking. The test reactor demonstrated the ability to engineer, construct, authorize, commission, and operate a full nuclear facility. Its next phase will build on this experience to help Oklo prepare the teams and systems needed to support the efficient delivery and operation of additional nuclear projects.<\/p>\n<p>\nThat preparation has already begun. During a recent reactor startup, operators wore eye-tracking glasses to record what they were looking at and for how long, giving the team data to improve the facility\u2019s human-machine interface and inform future design choices. Groves-1 will also serve as a key training and qualification platform for nuclear personnel at future reactor deployments, alongside further equipment testing, including continued evaluations of control rod drive mechanism performance and reliability.<\/p>\n<p>\nAdditionally, Groves-1 will enable criticality and reactivity benchmarking operations that support Oklo\u2019s isotope production capabilities, its engineering and design models, and potentially light water reactors and the large light water reactor fleet. The resulting data could also help improve fuel performance and power output in small and large light water reactors.<\/p>\n<p>\n\u201cTaking Groves-1 from greenfield to criticality in less than a year was an important demonstration of what our team can accomplish,\u201d said Oklo CEO and co-founder Jacob DeWitte. \u201cNow we&#8217;re building on that experience by operating the reactor, testing new capabilities, and learning directly from the work. Those lessons can help us develop the people, systems, and processes needed as we advance additional isotope projects and Aurora powerhouses.\u201d<\/p>\n<p>\n\u201cDOE\u2019s Reactor Pilot Program reset the nuclear industry\u2019s expectations for how quickly we can move from advanced reactor design to demonstration while upholding best-in-class safety standards,\u201d says acting Deputy Assistant Secretary for Nuclear Reactors Chimi Zacot. \u201cSuccesses like Groves-1&#8217;s criticality are now paving the way for what comes next.\u201d<\/p>\n<p>\nGroves-1\u2019s operating experience will directly inform Groves-2 Forge, Oklo\u2019s planned isotope production and processing pilot facility selected under DOE\u2019s Nuclear Energy Launch Pad initiative. Groves-2 Forge will integrate historically fragmented parts of the isotope value chain, combining reactor irradiation with hot-cell processing capabilities. Facility capabilities will include isotope separation, product recovery, packaging, and transportation, with initial focus on lutetium-177, an isotope used in targeted cancer treatments.<\/p>\n<p><b>About Oklo Inc.: <\/b>Oklo Inc. is developing fast fission power plants to deliver clean, reliable, affordable energy at global scale; establishing a domestic supply chain for critical isotopes; and advancing nuclear fuel recycling to convert used nuclear fuel into clean energy. Oklo was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission.
