[edit] Summary
A graphical representation of uranium resources. Areas of the squares are relative to the size of resource. Larger squares include also the contents of the smaller squares inside them. The smallest square represents the available uranium in existing mines according to World Nuclear Association. The second square includes also the NEA/IAEA estimate of available uranium resources at a market price of 130$/kg, as published in their Red Book. The third square is an estimate of the economic, conventional uranium reserves yet to be found by NEA and IAEA. The fourth represents an US DOE estimate of the total reserves of uranium in Earth's crust in the concentrations that are of interest at present mining techniques and uranium prices. The largest square represents the total potential of recoverable uranium with future technologies in the Earth's crust, estimated by NEA and IAEA to be at least 4 billion tonnes.
The numbers in the lower edges of the squares represent how long the given resource would last at current consumption of uranium, with no fuel recycling or breeding technology.
