AREVA Malvési: the first step in the conversion of uranium

The AREVA Malvési industrial site provides the first step in the conversion of uranium concentrate taken from mining sites into uranium tetrafluoride (UF4) for electricity companies across the globe. This transformation is carried out at the AREVA Pierrelatte industrial site (in France's Drôme region), which converts the uranium tetrafluoride into uranium hexafluoride (UF6), the final step before enrichment.

Operations: the conversion of natural uranium

The Malvési plant purifies the uranium ore concentrate to a very high level. It then carries out the first step in the fluorination process.
