— The cost of the equipment for mining and milling uranium into uranium ore concentrate, which generally takes place on site, is over US $100 million and can even reach into the billions. Thus, private companies and state entities alike must carefully consider long-term economics before opening a mine. Many countries that are new to …

The uranium fuel cycle is a process chain consisting of various stages. The uranium fuel cycle uses an enriched fuel (~4% of U-235) as a fresh fuel. During the fuel burning, the content of the U-235 decreases, and the content of the plutonium increases (up to ~1% of Pu ). Most PWRs use uranium fuel, which is in the form of uranium dioxide.

Natural uranium is mildly radioactive and contains ~99.28% uranium-238 (238 U), ~0.71% uranium-235 (235 U) and traces of uranium-234 (234 U). The 235 U nucleus, when struck by a neutron, will nearly always fission, or split into two or more smaller nuclei (fission products), while releasing heat energy (Figure 1).

Tailings: Milling uranium ore produces tailings. Tailings are what is left over once the uranium has been removed from the ground rock and resemble fine sand. They contain long-lived radionuclides (such as thorium-230 and radium-226) produced from the decay of uranium, as well as trace metals like arsenic and nickel.

Yellowcake, chemically U 3 O 8, is a uranium concentrate powder recovered from leach solutions. Yellowcake is an intermediate step in processing uranium ores and nuclear fuel production. Typically, yellowcake can be obtained through the conventional milling and chemical processing of uranium ore, forming a coarse powder.

Before the Second World War, uranium deposits were mainly valuable for the radium, which is a decay product of uranium and is always found in uranium-bearing ore. Discovered by Marie Curie in 1898, radium soon found use in the treatment for cancer and in self-luminous paints on the dials of watches and clocks.
