2. Packaging used in the light water nuclear reactor cycle
Upstream materials are characterized by low activity, requiring little or no biological protection. However, their physico-chemical form gives them subsidiary properties which may bring them within the scope of other hazard classes. For example, uranium hexafluoride is also a corrosive product (class 8), and uranium chemical compounds are also considered aquatic and marine pollutants.
2.1 Ore concentrates
Concentrates are obtained from processing plants located near the mines. The resulting product (yellow cake, ranging in color from yellow to dark gray) is almost universally transported in 220-liter (55 gal.) industrial drums with full opening. These drums are placed in 20-foot ISO containers (figure
