The Orano Malvési plant in Aude is responsible for the first phase of conversion purifying the natural uranium ore from the mines into uranium tetrafluoride (UF4). The degree of purification achieved by Orano’s process in Malvési is such that any type of uranium ore can be treated, regardless of origin. The second stage, making it possible to complete its transformation into uranium hexafluoride (UF6), is carried out at the Orano Tricastin site in Drôme.
A modernized industrial site
Comurhex II : 3 new workshops for heightened performance
In order to modernise its industrial facility, and more specifically to reduce the environmental impact of its conversion activities, Orano Malvesi built three new workshops to replace the historic Comurhex 1 factory. Comurhex II has been fully operational
Facilities offering greater safety The new workshops benefit from greater automation facilitating operational management. They are also equipped with control sensors ensuring greater security of operations.
New technologies for the benefit of the environment The technical developments at Comurhex II, in particular thanks to thermal and no longer chemical denitratation, make it possible to recycle 50% of the nitric acid
used and to reduce ammonia consumption by 75%. Another innovation lies in the cooling circuit for closed loop installations, which divides water sampling in the natural environment by 10.
An integrated management system (SMI)
The sustainable development and continuous progress policy at Orano Malvesi contributes to ensuring that the site’s activities are compliant with stringent environmental and social standards. It is validated by
a triple certification.
