Innovation
For more than 30 years, Urenco has sat at the forefront of isotope separation. Our expertise is rooted in the high-speed centrifuge technology originally developed for the energy sector, which we have refined to produce over 10 different stable isotopes with extreme purity. This deep technical knowledge allows us to offer more than just a product; we provide the consultative expertise required to solve complex isotopic challenges.
Urenco begins applying its world-leading centrifuge technology to the production of stable isotopes, establishing a dedicated facility in the Netherlands.
Significant investment in chemical processing laboratories allows for the delivery of isotopes in a variety of tailor-made chemical forms (Oxides, Metals, and Acetates).
Urenco becomes a primary supplier of Depleted Zinc for the global nuclear industry and a key partner for medical radioisotope precursors.
With the launch of our new “Leonardo” cascades, we continue to expand our capacity to meet the growing global demand for high-purity medical and research isotopes.

We are more than a supplier; we are a strategic production partner. Here is why global leaders in medicine, industry, and research choose Urenco:
We own the entire process. From our facility in the Netherlands, we manage everything from enrichment to chemical conversion, ensuring total quality control.
In an uncertain global market, we provide a reliable, transparent, and stable Western supply chain you can trust.

Our world-leading technology allows us to achieve extreme purity, with enrichment levels reaching 99%+ and depletion below 1%.
We don’t just provide off-the-shelf products. We deliver isotopes in bespoke chemical forms and isotopic compositions designed for your specific application.
We operate to the highest international standards. We welcome customer audits and site visits to demonstrate our commitment to excellence and regulatory compliance.
