The U.S. Department of Energy's decision to allocate HALEU recovered from Experimental Breeder Reactor-II fuel to Oklo was a stopgap measure that helped keep the company's first Aurora project moving when no U.S. commercial facility could produce the material. The arrangement, announced in early 2020 after a competitive process launched in 2019, remains a key precedent for federal support of advanced reactor fuel supply.
A bridge fuel for the first Aurora
DOE, through Idaho National Laboratory, established a supply from repurposed EBR-II material. That uranium will be used to start up the first Aurora powerhouse being built at INL in Idaho. The allocation gave Oklo access to HALEU at a time when the U.S. had no commercial plants able to produce such material.
The policy significance is twofold. First, it demonstrated that federal research inventories could be repurposed for commercial advanced reactor fuel. Second, it created a template for bridging the gap between reactor licensing and the build-out of domestic enrichment capacity.

From stopgap to commercial supply
The Centrus agreements now supplement that federal allocation. The definitive contracts secure HALEU for the first phase of the 1.2 GW Ohio campus, future Aurora deployments, and later refueling of the Aurora-INL reactor. Deliveries from Centrus's American Centrifuge Plant in Pike County, Ohio, are scheduled to begin in 2029.
Oklo has also marked several regulatory firsts. It received the first DOE site use permit for a commercial advanced fission plant and submitted the first custom combined license application for an advanced reactor to the Nuclear Regulatory Commission. Those milestones, combined with the EBR-II fuel allocation, positioned the company to move from demonstration to commercial deployment.
The EBR-II allocation is not a long-term solution. It is finite, and it was never intended to supply a fleet of reactors. But it illustrates how policy tools—competitive allocation, national laboratory infrastructure, and federal fuel inventories—can reduce early-stage fuel risk while commercial HALEU capacity is being built. For other advanced reactor developers, the Oklo case may serve as a model for securing bridge fuel without waiting for the commercial market to mature.
