Standard Nuclear announced it has raised $140 million in Series A funding and has begun production of advanced HALEU TRISO nuclear fuel, positioning the company to scale domestic supplies of a key fuel form used in next-generation reactors. The round was led by Decisive Point, with participation from new investors Chevron Technology Ventures, StepStone Group, and XTX Ventures. Standard Nuclear said the financing also included support from existing investors Welara, Fundomo, Andreessen Horowitz, Washington Harbour Partners, Crucible Capital, and others.
The company, known as a reactor-agnostic producer of TRISO fuel, said the financing will accelerate expansion beyond its existing, privately funded, commercial-scale TRISO manufacturing line.
The company said it plans to use the new capital to expand annual TRISO production to more than two metric tons across multiple strategically located sites by mid-2026. Standard Nuclear said it intends to leverage established infrastructure and a team it characterized as capable of rapid, high-quality execution as it builds out additional fuel development and fabrication capacity.
Standard Nuclear also pointed to what it described as a series of milestones achieved in its first 12 months, including selection as a supplier for the U.S. Department of Energy Office of Nuclear Energy’s Fuel Line Pilot Program, an agreement with DOE to transition its jurisdiction, and a joint venture with Framatome to supply commercial qualities of TRISO and proprietary advanced reactor products. The company added that it was the first to both receive authorization from the U.S. Department of Energy and physically receive HALEU for the production of advanced TRISO fuel for Radiant Industries.
Standard Nuclear said its broader focus spans large-scale production of advanced nuclear fuel and radioisotope power systems for space and defense applications, and it framed its strategy as supporting a domestic advanced nuclear fuel supply chain intended to reduce reliance on geopolitical adversaries.
