Orano offers customers customized solutions for every stage of nuclear energy production: from mining, conversion, enrichment, reprocessing, logistics and engineering to decommissioning and dismantling. The company operates uranium mines in Canada, Kazakhstan and Niger and is one of the world's leading uranium producers. It's offering competitive production costs and advanced recovery technologies. In addition to mining, Orano carries out exploration and development projects in uranium-bearing zones, as well as the rehabilitation and modernization of former mines. Orano is also a world leader in uranium processing, ensuring its customers the efficient, safe and responsible management of spent nuclear fuel. By recovering 96% of recycled materials (95% uranium and 1% plutonium) from spent fuel Orano can reprocess the material and produce new fuel, such as mixed oxide fuel (MOX) for nuclear reactors.
