How is radioactive waste produced? | UK Radioactive Waste ...

Uranium mining is the first step in the nuclear fuel cycle. The mine separates out uranium-bearing minerals from other minerals by crushing and milling the uranium ore. The uranium-rich product is a yellow powder, called 'yellowcake' because of its colour. Yellowcake is a uranium oxide and is the raw material for manufacturing nuclear fuel.

Through a number of chemical processes vanadium, and then uranium, were precipitated from solution at the Old Rifle mill. This eventually resulted in yellowcake—a uranium oxide product. The yellowcake was sent to Hanford, Washington, for further processing into plutonium, or to Oak Ridge, Tennessee, to produce uranium metal.

Exposure to ionising radiation in the mining and milling of uranium ores can come externally from gamma radiation emitted from ore and process materials or internally from the inhalation of radon decay products, uranium ore or uranium product dust. Internal exposure is also possible through the ingestion of materials.

Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

Nuclear Fuel Cycle Overview - World Nuclear Association

The uranium oxide product of a uranium mill is not directly usable as fuel for a nuclear reactor – additional processing is required. Only 0.7% of natural uranium is 'fissile', or capable of undergoing fission, the process by which energy is produced in a nuclear reactor. The form (or isotope) of uranium which is fissile is uranium-235 (U-235).

Uranium: How is it Mined?

The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry. This slurry is then mixed with sulfuric acid or an alkaline solution to release the uranium from the host rock. Normally approximately 95 - 98% of the uranium can be recovered from the host rock.
