What Standard Nuclear does
Standard Nuclear is a US-based advanced nuclear fuel manufacturer specializing in TRISO (TRi-structural ISOtropic) particle fuel, a high-assurance ceramic-coated fuel form designed for next-generation reactor designs including high-temperature gas reactors, molten salt reactors, and microreactors. Headquartered in Oak Ridge, Tennessee, the company operates the only privately funded industrial-scale TRISO fuel production line in the United States. Its product portfolio consists of Standard TRISO fuel (using low-enriched uranium) and HALEU (High-Assay Low-Enriched Uranium) TRISO fuel, the latter targeting advanced reactor developers that require uranium-235 enrichment levels above the conventional 5% threshold. The company sells fuel under multi-year supply contracts to advanced reactor developers and government customers.
Founded in 2023, Standard Nuclear acquired the fuel manufacturing business and intellectual property of Ultra Safe Nuclear Corporation (USNC) for $32.5 million in 2024, providing inherited qualification data, manufacturing know-how, and customer relationships. Its commercial customer base includes advanced reactor developers such as Radiant Industries and Oklo, alongside procurement work for the US Department of Energy. The business model is anchored on long-duration fuel supply agreements, with a disclosed contract backlog of approximately $245 million against current trailing-twelve-month revenue of roughly $3 million, indicating significant forward revenue conversion potential as production capacity comes online.
Standard Nuclear's positioning combines regulatory first-mover status (first private HALEU TRISO authorization, August 2025 DOE Fuel Line Pilot selection), inherited USNC manufacturing assets, and a September 2025 joint venture with Framatome to scale commercial fuel production. The company completed a $140 million Series A in January 2026 and filed for an initial public offering in June 2026 to fund capacity expansion at its Oak Ridge facility and a planned Idaho Falls site, alongside workforce expansion to over 40 employees as of early 2026.

Standard Nuclear product offering
Product offeringCore offering
Standard Nuclear manufactures TRISO (TRi-structural ISOtropic) nuclear fuel and advanced HALEU TRISO fuel at industrial scale for small modular reactors, microreactors, defense applications, and space power systems. The company operates the only privately funded industrial-scale TRISO production line in the United States, using a modular manufacturing architecture to produce diverse fuel designs on a single production line. Standard Nuclear converts uranium feedstock into precision-engineered TRISO fuel particles with multiple protective layers (kernel, buffer, inner pyrolytic carbon, silicon carbide, outer pyrolytic carbon) for advanced reactor developers and the U.S. government.
Product overview
Standard Nuclear is a reactor-agnostic producer of TRISO nuclear fuel, offering both standard TRISO fuel and advanced HALEU TRISO fuel variants. The company operates the only privately funded industrial-scale TRISO production line in the United States, acquired from Ultra Safe Nuclear Corp. through a bankruptcy auction in 2024. Their modular manufacturing architecture allows production of diverse fuel designs on a single production line. The company supplies fuel to advanced reactor developers including Radiant Industries and operates a joint venture with Framatome for commercial TRISO fuel supply.

Products and services
- TRISO Nuclear Fuel TRISO (TRi-structural ISOtropic) nuclear fuel is the world's most advanced nuclear fuel, consisting of multi-layered particles containing uranium with protective carbon and ceramic layers (kernel, buffer, inner pyrolytic carbon, silicon carbide, outer pyrolytic carbon) for unmatched safety and performance in advanced reactors. Produced at industrial scale for SMR and microreactor developers, defense, and space applications.
- HALEU TRISO Fuel High-Assay Low-Enriched Uranium (HALEU) TRISO fuel is an advanced variant with higher enrichment levels (typically 5-20% U-235) required for small modular reactors and microreactors, produced at Standard Nuclear's industrial-scale manufacturing line as the first company authorized by the DOE to receive HALEU feedstock.

Standard Nuclear partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered core and strategic.
- OklocoreMemorandum of understanding for strategic alliance to strengthen advanced nuclear fuel supply chain. Standard Nuclear serves as Oklo's initial third-party buyer for materials processed at its planned Oak Ridge, Tennessee facility. Under the agreement, Standard Nuclear will produce TRISO fuel using reprocessed uranium and uranium-transuranic streams from Oklo's recycling plant. Both companies coordinate on licensing, secure transportation, and converting surplus weapons-grade plutonium into fuel for next-generation commercial reactors.
- FramatomecoreJoint venture announced to establish U.S.-based TRISO nuclear fuel production capability. The partnership aims to supply commercial quantities of TRISO fuel for advanced reactors, combining Standard Nuclear's TRISO fuel manufacturing expertise with Framatome's nuclear industry experience.
- SHINE TechnologiesstrategicStrategic partnership to enhance nuclear fuel recycling and U.S. fuel security. SHINE will develop recycling facilities starting in the early 2030s to process used nuclear fuel and supply recycled uranium, plutonium, strontium-90, and americium-241 to Standard Nuclear for TRISO fuel production and radioisotope power systems. The partnership aims to establish a closed-loop domestic nuclear fuel production solution.

Standard Nuclear competitors and assessment
Company assessmentDirect peers
- X-energy: X-energy is developing the Xe-100 high-temperature gas reactor and TRISO-X fuel; a direct competitor to Standard Nuclear in advanced TRISO fuel manufacturing, also pursuing DOE programs and supplying SMR/microreactor developers.
- TRISO-X (Ultra Safe Nuclear Corp.): Ultra Safe Nuclear's TRISO-X subsidiary was Standard Nuclear's predecessor asset seller in the 2024 bankruptcy auction; TRISO-X continues to pursue DOE pilot programs and serves the same advanced reactor customer base with overlapping TRISO fuel technology.
- SHINE Technologies: SHINE is a Standard Nuclear partner on fuel recycling and is also competing in the DOE Surplus Plutonium Utilization Program; it produces medical and fusion-related isotopes and is positioned as both a strategic ally and a competing advanced nuclear fuel/material player.
Broad incumbents
- Framatome: Framatome is a global nuclear fuel and services incumbent and Standard Nuclear's JV partner; it also manufactures light-water reactor and is developing TRISO/advanced fuel lines, making it both a partner and a long-term competitive threat in commercial TRISO supply.
- Centrus Energy: Centrus is the only U.S.-licensed HALEU producer and a key feedstock supplier to Standard Nuclear's TRISO line; Standard Nuclear's CFO previously led Centrus, and Centrus sits directly upstream of Standard Nuclear's fuel cycle.
- BWX Technologies (BWXT): BWXT manufactures TRISO fuel for the U.S. Department of Defense and operates advanced reactor fuel programs; it is a broader nuclear-fuel incumbent with TRISO capabilities relevant to defense and space missions that overlap with Standard Nuclear's stated verticals.
- Westinghouse Electric Company: Westinghouse is a global nuclear fuel fabricator (LWR) and is pursuing accident-tolerant and advanced fuel lines; as a broad incumbent with deep NRC licensing experience, it is a comparable long-term competitor if it enters the TRISO/advanced fuel market.
Emerging players
- Lightbridge Corporation: Lightbridge is developing proprietary metallic nuclear fuel for SMRs and existing reactors; while its fuel form differs from TRISO, it targets the same advanced reactor and data-center power generation use cases that drive Standard Nuclear's demand.
Regional players
- Oklo: Oklo is a Standard Nuclear customer and strategic partner, but is also a downstream reactor developer (Aurora microreactor) competing for the same advanced reactor fuel dollars; both companies are pursuing the same domestic microreactor/AI data-center power opportunity.
Others
- Radiant Industries: Radiant is Standard Nuclear's first commercial HALEU TRISO customer for its Kaleidos microreactor; not a fuel competitor but a critical demand anchor whose commercial trajectory directly drives Standard Nuclear's orderbook conversion.
