What Nuclearis does

Nuclearis is an Argentinian engineering and manufacturing company specializing in mechanical components and software for the nuclear industry. Founded in 2009 and headquartered in Villa Martelli, Buenos Aires, the company designs, fabricates, and qualifies Class 1 nuclear-grade components — including seal rings, Cobalt 59 slugs, primary circuit valves, end fittings, refueling machine encoder discs, and autonomous safety systems for spent fuel pools — that historically were imported from European suppliers before Nuclearis localized production. It holds ASME III Nuclear Certification (NPT for Class 1, 2 & 3 fabrication) and ASME Material Organization (MO) Certification, the first and only such dual certifications in Latin America, alongside ISO 9001.

The company operates two principal lines of business. The first is precision mechanical manufacturing under ASME III, including custom-built automated production lines using FANUC robotics, CNC-controlled Hastelloy cladding welding, electrolytic coatings of special alloys, and metal 3D printing, sold primarily to Nucleoeléctrica Argentina S.A., CNEA, DIOXITEK S.A., and the Atucha I and II nuclear power plants. The second is a suite of Blockchain-based traceability and documentation platforms — NUCLEARISTRACK, ORANGETRACK (with ORBCOMM), PHARMATRACK (with Molecular Dynamics), MATTERIA, and DOSETRACK — that apply RSK and Polkadot protocols to nuclear manufacturing traceability, radioactive source tracking, pharmaceutical chain-of-custody, ASME III documentation, and occupational radiation dose monitoring.

Nuclearis generates revenue through project-based engineering contracts (basic and detailed engineering for reactors including CAREM-25 and RA-10) and direct supply contracts for manufactured components, with all named customers being government or intergovernmental entities concentrated in Argentina. Pricing is not publicly disclosed and the company pursues enterprise field sales directly to nuclear utilities and atomic energy agencies, with limited export activity routed through state partner DIOXITEK and a New Mexico subsidiary established in 2018.
