Ultra Safe Nuclear Company is a technology company.
Ultra Safe Nuclear Company (USNC) develops and deploys advanced nuclear energy systems, centered on its Micro Modular Reactor (MMR) and specialized nuclear fuels. The company's core technological approach utilizes Fully Ceramic Micro-encapsulated (FCM) and TRISO particle fuels, designed for enhanced safety and performance in high-temperature gas-cooled reactors. These innovations support a range of applications, including terrestrial power generation and advanced nuclear thermal propulsion for space exploration.
The company was founded in 2011 by Francesco Venneri, an experienced nuclear physicist. Venneri’s insight was to address the demand for safe, carbon-free energy by developing inherently secure and passively cooled microreactors, leveraging advanced materials and fuel designs from his background in nuclear science. This foundational principle aimed to simplify reactor operations and expand deployment possibilities for fission energy.
USNC's products serve diverse customers, including utilities seeking reliable grid power, heavy industry requiring process heat, and governmental agencies involved in defense and space exploration. The company’s long-term vision is to provide reliable, zero-carbon energy anywhere, from remote terrestrial locations to deep space missions. By integrating fuel manufacturing, reactor design, and deployment capabilities, USNC aims to deliver commercially competitive and environmentally responsible nuclear energy solutions globally.

Ultra Safe Nuclear Corporation (USNC) is a private technology company that designs, licenses, and manufactures micro–small modular reactors (micro/SMRs) and associated nuclear fuels and components to deliver safe, clean, dispatchable power and heat for off‑grid, remote, industrial and specialized applications (including space and nuclear propulsion R&D). [2][7]
High‑Level Overview
As a portfolio/company summary: USNC builds the MMR (micro modular reactor) family and related fuel and component technologies to serve remote industrial sites, utilities and government agencies, solving the problem of providing reliable, low‑emissions, dispatchable power where grid access or emissions constraints limit alternatives; the company has progressed to licensing and demonstration projects (notably the Global First Power joint venture and Chalk River demonstration planning) and has attracted substantial private funding and government contracts that indicate growth momentum toward commercialization and licensing.[2][3][4]
