Fuel manufacturing is the last stage of processing before uranium fuel is ready for use in a reactor. The process begins by pressing either natural or enriched UO 2 powder into small cylindrical shapes, measuring about 10 - 13 millimeters in length and 8 - 13.5 millimeters in diameter. These pellets are then baked at a high temperature (1600 – 1700°C), where they acquire their ...

NRC: Conventional Uranium Mills

Uranium-238, the most prevalent isotope in uranium ore, has a half-life of about 4.5 billion years; that is, half the atoms in any sample will decay in that amount of time. Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on.

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.
