Further exploration and higher prices will certainly, on the basis of present geological knowledge, yield further resources as present ones are used up.
Reducing the tails assay in enrichment reduces the amount of natural uranium required for a given amount of fuel.
Japanese (JAERI) research in 2002 using a polymeric absorbent in a nonwoven fabric containing an amidoxime group that was capable of forming a complex with uranyl tricarbonate ions, suggested about 0/kg U. The total recoverable identified resources to US$ 260/kg U is 7.989 million tonnes U.
Identified resources in situ to US$ 130/kg U are 8.122 Mt, and to US$ 260/kg U, 10.653 Mt. Uranium has been successfully mined since the 1940s.
Reprocessing of used fuel from conventional light water reactors also utilises present resources more efficiently, by a factor of about 1.3 overall.
The 2016 recognised these trends, along with more efficient plant operation, and as a result of which, the report’s generic reactor fuel consumption was reduced from 175 t U per GWe per year at 0.30% tails assay (2012 report) to 160 t U per GWe per year at 0.25% tails assay (2016 report).
Under the programme, enough bomb-grade material for 20,000 nuclear warheads was eliminated.This means that it needs to be in a mineral form that can easily be dissolved by sulfuric acid or sodium carbonate leaching.Total world resources of uranium, as with any other mineral or metal, are not known exactly.The corresponding U figures are 206 tonnes and 189 tonnes.Note that these figures are generalisations across the industry and across many different reactor types.

(Over the years 1980 to 2008 the electricity generated by nuclear power increased 3.6-fold while uranium used increased by a factor of only 2.5.) The world's present measured resources of uranium (5.7 Mt) in the cost category less than three times present spot prices and used only in conventional reactors, are enough to last for about 90 years.
