Storage of depleted uranium
The counterpart of enriching uranium with isotope 235 to provide fuel for nuclear reactors is the accumulation of relatively large quantities of depleted uranium. There were 271,000 tonnes at the end of 2010, and there are expected to be 345,000 tonnes by 2020. This uranium is stored, mainly at Pierrelatte on the Tricastin site as U3O8, but also at Bessines-sur-Gartempe (87). These stocks are significant but are still minimal in comparison with other raw materials such as coal and oil. This material is not very radioactive at all.
