- Uranium (U): a mildly radioactive element with two isotopes which are fissile (U-235 and U-233) and two which are fertile (U-238 and U-234).
- Uranium is the basic fuel of nuclear energy. Nuclear power plants use fuel rods typically in 3 operational cycles, totalling about 6 years, till 3% has been fissioned. Spent nuclear fuel, after some 5 years in a pool for cooling and decaying, will be stored and eventually moved to a repository or reprocessed to generate new fuel.
- In 2008, 65,000 tonnes of uranium are required to feed the 372 GWe-generating operating nuclear reactors. It is estimated that there is ample uranium at low cost to sustain three times the global power generation of today.
- Uranium is sold in the form of uranium oxide concentrate (U3O8), which is a mixture of uranium oxides produced after milling ore uranium from a mine. Sometimes loosely called "yellow cake", because of its khaki colour.
