The company announced the clearance in a [Business Wire](https://www.businesswire.com/news/home/20261111613764/en/) release on November 11, 2026.\n\n## What the Groves-1 Clearance Allows\n\nGroves-1 reached first criticality at low power in August 2026 under the DOE Reactor Pilot Program, less than a year after groundbreaking, according to the release. Oklo said the reactor demonstrated the ability to engineer, construct, authorize, commission and operate a full nuclear facility.\n\nWith unrestricted operations, Oklo will test capabilities relevant to future isotope reactors and to its fast fission reactors, the Aurora powerhouse. 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's human-machine interface and inform future design choices.\n\nGroves-1 will also serve as a training and qualification platform for nuclear personnel at future reactor deployments, alongside continued evaluations of control rod drive mechanism performance and reliability. The facility will enable criticality and reactivity benchmarking operations supporting Oklo's isotope production capabilities and engineering and design models.\n\n\"Taking Groves-1 from greenfield to criticality in less than a year was an important demonstration of what our team can accomplish,\" said Oklo CEO and co-founder Jacob DeWitte. \"Now we're building on that experience by operating the reactor, testing new capabilities, and learning directly from the work.\"\n\n## Oklo's Funding and Customer Pipeline\n\nOklo designs, builds, owns and operates Aurora small modular fast fission power plants of up to 75 MWe, sold through long-term power purchase agreements to data center, industrial and government customers, according to akta.pro [company records](https://akta.pro/company-data). The same records show a $2.5 billion cash position at the end of the first quarter of 2026, after a $1.2 billion at-the-market equity offering, and more than 14 GW in non-binding letters and binding agreements, anchored by Meta at 1.2 GW, Switch at 12 GW and Equinix at 500 MW.\n\n## Earlier Oklo Milestones Before the Clearance\n\nOn November 9, 2026, Yahoo reported that Oklo is shifting from design to execution as its Groves-1 test reactor becomes operational. On November 6, 2026, FinancialContent Business Page reported that Oklo announced a manufacturing agreement with US Forged Rings to reserve domestic capacity for large reactor components for its Aurora powerhouses. On November 3, 2026, The Motley Fool reported that Oklo has achieved low-power criticality at Groves and holds billions in cash, with its 2028 start-up and fuel strategy remaining key.\n\n## Groves-2 Forge and Isotope Plans\n\nOklo said Groves-1's operating experience will directly inform Groves-2 Forge, its planned isotope production and processing pilot facility selected under DOE's Nuclear Energy Launch Pad initiative. Groves-2 Forge is designed to combine reactor irradiation with hot-cell processing, including isotope separation, product recovery, packaging and transportation, with an initial focus on lutetium-177, an isotope used in targeted cancer treatments.\n","publisher":{"name":"News for Agent","url":"https://newsforagent.com"}}
