Current usage is about 65,000 tU/yr. Thus the world's present measured resources of uranium (5.5 Mt) in the cost category somewhat below present sprabroad
prices and used only in conventional reactors, are enough to last for over 80 years. This represents a higher level of assured resources than is normal for most minerals. Further exploration and higher prices will certainly, on the basis of present geological knowledge, yield further resources as present ones are used up.
...
This is in fact suggested in the IAEA-NEA figures if those covering estimates of all conventional resources are considered - 10.5 million tonnes (beyond the 5.5 Mt known economic resources), which takes us to over 200 years' supply at today's rate of consumption. This still ignores the technological factor mentioned below. It also omits unconventional resources such as phosphate/ phosphorite deposits (22 Mt U recoverable as by-product) and seawater (up to 4000 Mt), which would be uneconomic to extract in the foreseeable future.

Widespread use of the fast breeder reactor could increase the utilisation of uranium 50-fold or more. This type of reactor can be started up on plutonium derived from conventional reactors and operated in closed circuit with its reprocessing plant. Such a reactor, supplied with natural or depleted uranium for its "fertile blanket", can be operated so that each tonne of ore yields 60 times more energy than in a conventional reactor.
