Oklo Inc. has taken a major step forward in developing its first advanced nuclear reactor, announcing federal approval tied to its Aurora powerhouse project at Idaho National Laboratory.
The company confirmed it has signed an agreement with the U.S. Department of Energy to support the design, construction and operation of the Aurora facility under the agency’s Reactor Pilot Program, marking a significant milestone in next-generation nuclear deployment.
The agreement includes approval of a Nuclear Safety Design Agreement (NSDA), a critical step in the Department of Energy’s authorization process for advanced reactors. With this milestone, the Aurora project moves into its next execution phase under federal oversight.
“The OTA sets the program structure, while the design agreement reflects DOE’s rigorous authorization process and safety-first approach,” said Jacob DeWitte. “DOE’s pathway for the Aurora-INL supports a stepwise approach to deploying our first powerhouse while we continue progressing our engagement for future commercial licensing by the U.S. Nuclear Regulatory Commission.”
The project had already broken ground in September, and the latest approval enables federal review of its Preliminary Documented Safety Analysis, an essential component for demonstrating operational safety.
Federal officials emphasized that the project is part of a broader effort to strengthen domestic nuclear energy capabilities.
“DOE Idaho is committed to enabling safe, disciplined progress from design to demonstration,” said Robert Boston. “With the Aurora powerhouse NSDA—alongside the Aurora Fuel Fabrication Facility—we’re supporting an integrated Idaho effort that can help scale domestic nuclear capability for the next generation of secure and reliable energy.”
The Aurora-INL project is supported by parallel development of a fuel fabrication facility, which will produce the initial fuel assemblies needed for the reactor. That facility previously received its own approvals in late 2025 under a separate DOE pilot program.
Oklo’s Aurora powerhouse represents a new class of “fast fission” reactors designed to deliver reliable, low-carbon energy with improved efficiency and smaller footprints compared to traditional nuclear plants.
The Department of Energy’s Reactor Pilot Program is intended to accelerate deployment timelines by allowing projects to be built and tested under DOE authorization before transitioning to full commercial licensing through the U.S. Nuclear Regulatory Commission.
Oklo has also secured access to recycled nuclear fuel from the historic Experimental Breeder Reactor II, positioning the company to advance fuel recycling technologies alongside reactor development.
Industry experts note that projects like Aurora could play a critical role in addressing growing energy demand, particularly from data centers and electrification efforts, while supporting U.S. energy independence.
At the same time, advanced nuclear projects face challenges, including regulatory complexity, financing requirements and supply chain constraints—factors that will shape how quickly technologies like Aurora can scale commercially.
With DOE approvals now in place, Oklo is expected to continue progressing toward construction and operational milestones, while also preparing for future licensing pathways.
If successful, the Aurora project could serve as a model for deploying smaller, faster-to-build nuclear reactors across the United States, helping to expand clean energy capacity and modernize the nation’s power infrastructure.
