Standard Nuclear, Inc. designs, engineers, and manufactures TRISO fuel for next‑generation reactors. Its TRISO fuel uses uranium kernels encased in multiple ceramic and carbon layers to withstand extreme temperatures, and the company operates a toll‑manufacturing model where customers supply the uranium feedstock and Standard Nuclear converts it into finished fuel. Unlike many competitors, it does not own reactors and relies on a reactor‑agnostic production line in Oak Ridge, backed by privately funded IP and institutional investors. The company aims to support the growth of SMRs, microreactors, and other advanced systems by providing a reliable, scalable fuel supply that enhances decarbonization, energy security, and defense applications.

Standard Nuclear completes construction of two TRISO fuel facilities adding 5 MTU annual capacity

Standard Nuclear has completed construction of two new TRISO nuclear fuel production facilities in Tennessee and Idaho. The facilities, designated SN-TN and SN-ID, are expected to collectively add up to 5 metric tons of uranium per year of production capacity once fully scaled, with initial capacity of 1 MTU annually each. The company has received approval of Preliminary Documented Safety Analyses for both facilities from the US Department of Energy. Start-up, commissioning, and licensing activities are expected to advance over the summer. Standard Nuclear currently operates its SN-0 facility in Oak Ridge, Tennessee, which produces up to 0.5 MTU annually. The company is also building another fuel line through a joint venture with Framatome in Washington state. "This comprehensive milestone represents the core of our mission at Standard Nuclear: focused execution to scale quickly to meet the increasing customer demand for advanced nuclear fuel," said Kurt Terrani, chief executive officer.

Standard Nuclear targets $3.5B valuation in IPO as AI power demand fuels nuclear boom

Standard Nuclear, a Tennessee-based manufacturer of advanced nuclear fuel, is targeting a valuation of up to $3.5 billion through its upcoming IPO. The company plans to offer 18.25 million Class A shares priced between $18 and $21 each. This represents a significant jump from the $838 million valuation in its January funding round. Standard Nuclear produces TRISO fuel, a highly robust micro-particle nuclear fuel designed for small modular reactors that could power AI data centres. The company reported a net loss of $7.7 million on revenue of $593,802 for Q1 2025, compared to an $8.3 million loss on $377,926 in revenue the previous year. Despite losses, revenue grew 57% year-over-year. Standard Nuclear reports a contract backlog of up to $245 million and estimates the cumulative TRISO fuel market opportunity at over $4 billion through 2030.
