Oklo Advances HALEU-Powered Reactor Projects with Groves-2 and Launch Pad

Oklo Expands Its Advanced Reactor Footprint

Oklo, a leading developer of advanced nuclear reactors designed to utilize high-assay low-enriched uranium (HALEU) fuel, is rapidly advancing its project portfolio. The company recently revealed detailed plans for its Groves-2 project, which represents the next phase of its broader Groves initiative. This new phase will build upon the progress achieved under the Department of Energy's (DOE) Reactor Pilot Program.

Integration with the Nuclear Energy Launch Pad

A critical enabler for the Groves-2 project is the DOE's Nuclear Energy Launch Pad Program. Oklo was among the 13 projects across 12 companies selected in the second round of this initiative, announced by the Idaho National Laboratory’s National Reactor Innovation Center in late August 2026. The Launch Pad program is designed to integrate reactor and fuel facility authorization, testing, and deployment support, explicitly including enrichment technologies necessary for HALEU.

Oklo’s Groves-2 project will build on progress from the DOE's Reactor Pilot Program and be enabled by the Nuclear Energy Launch Pad Program, initially focusing on medical isotope production.

Initially, the Groves-2 project will focus on medical isotope production, leveraging the unique capabilities of Oklo's advanced HALEU-fueled reactor design. This milestone follows a significant achievement in August 2026, when Oklo’s Groves Isotope Test Reactor in Lockhart, Texas, successfully achieved criticality. This made it the fifth DOE-authorized reactor to reach this crucial milestone under the agency’s authorization process.

Navigating Grid Interconnection Challenges

Despite these technical and regulatory advancements, Oklo continues to face commercial and grid-integration hurdles. In September 2026, the company filed an emergency request with the Federal Energy Regulatory Commission (FERC). Oklo claimed that its Aurora powerhouse project in Virginia was unjustifiably withdrawn from the PJM Interconnection queue. The company has formally asked FERC to reinstate its original queue position, highlighting the complex intersection of advanced HALEU reactor deployment and existing grid infrastructure frameworks.
