2D Modelling of a UF6 Container in a Fire

In France, large quantities of uranium hexafluoride are used in the various uranium enrichment and reprocessing plants. Natural or depleted UF6 is stored and transported in containers called 48Y. The risk entailed is essentially chemical not radiological so the containers used are classified as \"industrial-purpose\" and do not need to undergo any accident test. No fire test, in particular, is required. However, IAEA recommendations with a view to future regulations specifically mention a fire test on the UF6 containers, so this has become a priority research topic.
