Nusano Develops Novel Metallic Uranium Enrichment Technology
U.S. nuclear technology company Nusano is pioneering a revolutionary approach to High-Assay Low-Enriched Uranium (HALEU) production. Backed by federal support from the Department of Energy (DOE), Nusano is developing a compact production system that utilizes direct metallic uranium enrichment, fundamentally altering the traditional isotopic separation process.
Bypassing Traditional UF6 Conversion
Historically, uranium enrichment has relied on converting uranium into a gaseous state, specifically uranium hexafluoride (UF6), before separating the isotopes. Nusano’s novel technology completely bypasses this complex and hazardous step. Instead, the system feeds metallic uranium directly into the enrichment process and separates the isotopes in their solid metallic form. This innovative approach can increase the U-235 concentration in natural uranium to the HALEU threshold of 19.75% in a single pass.
By eliminating the need for conversion to UF6, reconversion, and complex fluorine chemistry, Nusano's technology promises to significantly reduce the environmental footprint and operational costs associated with HALEU production.
Compact Modular Production System
The practical application of this technology is a highly compact HALEU production system. A single module occupies approximately 111 square meters and is engineered to produce up to 5.9 tons of HALEU annually. This modular design allows for flexible deployment and scalable capacity, contrasting sharply with the traditional model of building massive, centralized enrichment plants.
Nusano's breakthrough has attracted significant attention under the DOE's Nuclear Energy Launch Pad program, which aims to accelerate the deployment of advanced nuclear technologies. The first module of this compact system is expected to be launched by 2031. If successful, Nusano's metallic enrichment technology could democratize HALEU production, offering a faster, cheaper, and more environmentally friendly pathway to supply the fuel required for the rapidly growing fleet of advanced reactors and small modular reactors (SMRs) worldwide.
