The uranium enrichment process leads to the production of much ...

What is Uranium? | IAEA

The nuclear fuel cycle is an industrial process involving various activities to produce electricity from uranium in nuclear power reactors. Exploration for uranium is followed by mining and milling of the raw uranium ore. Raw uranium must then be processed, and sometimes enriched, in order to maximise its efficiency as fuel.

Uranium: The Nuclear Fuel Cycle and Beyond

Uranium is mainly used in the nuclear fuel cycle sketched in Figure 2, an industrial process involving various activities to produce electricity from uranium in nuclear power reactors, i.e., the progression of nuclear fuel from creation to disposal. Typically, uranium is employed in the form of UO 2. During uranium decay, fissile plutonium is ...

Uranium:

The milling (refining) process extracts uranium oxide (U 3 O 8) from ore to form yellowcake, a yellow or brown powder that contains about 90 percent uranium oxide. [6] Conventional mining techniques generate a substantial quantity of mill tailings waste during the milling phase, because the usable portion is generally less than one percent of ...

The nuclear fuel cycle

Despite the name, the concentrated uranium product is typically a black or brown substance called yellowcake (U 3 O 8).Mined uranium ore typically yields one to four pounds of U 3 O 8 per ton of ore, or 0.05% to 0.20% yellowcake. The solid waste material from pit and underground mining operations is called mill tailings.The processed water …
