WATER REQUIREMENTS FOR ORANO’S ACTIVITIES AND ITS VALUE CHAIN

IRO

The activities of Orano and its value chain (upstream and downstream) require water resources. In the event of a water shortage, Orano’s use of water could impact ecosystems and local communities. RISK IN THE EVENT OF INSUFFICIENT WATER RESOURCES AT ORANO SITES OR IN THE UPSTREAM VALUE CHAIN A lack of water (water stress, conflict of use arbitrated against us) would impact the activities and the ability to deliver customers. Within a decade, some of our activities may have to adjust their production according to access to water resources. The need for water is a dependency on an ecosystem service. This could disrupt our customers’ production schedules and delivery commitments, and therefore ultimately our revenue or production costs.

Description

4.2.2.2 Water resources policy and actions A precious natural resource, water management is at the heart of Orano’s environmental and societal concerns, as for its stakeholders. Water is essential to the smooth running of operations, as well as to the well-being of communities and the environment in which the group operates, in a context of increased climate change tension.

Water within the group The group’s main water users are mining and chemistry-enrichment activities. Water is used in industrial processes and to a lesser extent for employees and communities. In the group’s mining activities, the processing of uranium ore is carried out in a wet process, which requires water. Groundwater pumping is essential to access deposits in surface and underground mines. On In Situ Recovery (SRI) operations, as in Kazakhstan, this pumping extracts the uranium dissolved in the solution.
