Standard Nuclear
Public, reactor-agnostic TRISO fuel manufacturer scaling U.S. capacity
The product
Advanced nuclear fuels, principally TRISO particles and reactor-specific fuel forms, through an operating Oak Ridge line, new Tennessee and Idaho facilities, and a joint venture using Framatome's licensed Richland, Washington site. The company serves multiple advanced-reactor developers rather than a captive reactor design.
The thesis
TRISO supply is a critical dependency for many U.S. advanced reactors. Standard Nuclear is already producing revenue and shipping fuel, completed the first commercial reactor core supplied by an independent U.S. manufacturer, went public on the NYSE in July 2026, and is converting developer demand into binding contracts with Radiant and Antares.
How it runs
Standard Nuclear is a reactor-agnostic advanced-fuel manufacturer: customers provide enriched uranium feedstock, and Standard engineers and fabricates TRISO fuel to customer-specific reactor requirements through modular production lines and a joint venture using Framatome's licensed Richland facility.
How it earns
It earns from fuel-development work, commercial fuel-sales agreements priced primarily per kilogram or metric ton of uranium, and government or specialized contracts. Fuel-sale arrangements typically use advance non-refundable deposits and milestone payments; exact customer-specific prices are undisclosed.
Why it wins
Its independent, reactor-agnostic position and modular manufacturing process let it serve multiple SMR and microreactor designs rather than one captive platform. The company reports the only U.S. industrial-scale TRISO fabrication capability and is scaling across multiple facilities and its Framatome joint venture.
