Standard Nuclear closes $140 million series A to boost domestic TRISO supply chain
For East Tennessee, the announcement adds to the region’s growing footprint in advanced nuclear manufacturing and fuel development.
On Monday, Standard Nuclear announced the closure of its $140 million Series A funding to expand its production of TRISO fuel, a nuclear fuel source critical for thenext wave of advanced reactor technologies.
The raise was reported as one of the largest early fundraising rounds in the advanced nuclear sector in recent years.
The round was led by Decisive Point with participation from several new investors, including Chevron Technology Ventures, StepStone Group, and XTX Ventures. Existing backers such as Andreessen Horowitz and Welara also joined the raise.
With the $140 million, the Oak Ridge-based company said it plans to expand its annual TRISO output to more than two metric tons by mid 2026. The company will expand at multiple sites across the country, building on its privately funded commercial-scale TRISO line that is already operational.
In the press release, CEO Kurt Terrani said the financing will allow Standard Nuclear to accelerate manufacturing growth.
“With this funding, we are positioned to accelerate our roadmap, scale operations, and deliver on the promise to fuel the next generation of reactors powering industry, defense, and space,” he said.
Why is TRISO fuel production so important?
TRISO fuel is known for its durability under extreme temperatures. It has become the centerpiece of many advanced reactor concepts designed for industrial settings, defense applications, and even space power systems. Today, domestic supply remains limited, and the federal government has repeatedly highlighted the need to build a resilient U.S. production base.
Standard Nuclear was selected as a supplier for the U.S. Department of Energy (DOE) Fuel Line Pilot Program and a joint venture with Framatome to produce commercial quantities of TRISO and related advanced reactor products.
In early 2026, Standard Nuclear also became the first company authorized by DOE to physically receive HALEU, the enriched uranium required for many next-generation reactor designs. It will use the material to produce TRISO fuel for Radiant Industries. In October 2025, Radiant Industries announced a $280 million investment to build a factory at the East Tennessee Technology Park (ETTP) for manufacturing portable nuclear microreactors.
For East Tennessee, the announcement adds to the region’s growing footprint in advanced nuclear manufacturing and fuel development.
