Uranium Supplies Are Sufficient To Power Reactors Worldwide Through 2030
Current uranium reserves should be adequate to meet additional demand as
worldwide installed nuclear capacity increases to the 498 gigawatts in
2030 projected in the IEO2008 reference case. According to results from
the demand model used by the OECD Nuclear Energy Agency and the International
Atomic Energy Agency, annual uranium requirements are expected to grow
from 68,000 metric tons per year in 2005 to 96,000 metric tons per year
in 2030.a The cumulative demand for uranium to meet the projected increase
in nuclear electricity generation from 2005 to 2030 would be 2.1 million
metric tons.b,c

Uranium resources are divided into four groups, based on the confidence
of supply estimation. Reasonably assured resources (RAR) are known uranium
deposits that can be recovered with current mining technologies and methods. Inferred resources are uranium deposits that are believed to exist, based
on direct geological evidence, but have not been studied as thoroughly
as RAR. Resources could be expanded even further with prognosticated resourcesuranium
deposits expected to exist on the basis of indirect evidenceand speculative
resources thought to exist on the basis of geological extrapolations.d The table below shows the two groups of worldwide uranium reserves estimated
with the highest confidence, at various production cost levels.
Even in the lowest cost tier, less than $40 per kilogram, total uranium
reserves should be sufficient to meet the requirements for projected nuclear
capacity in 2030. In addition, with the spot price of uranium oxide having
risen from $14.1 per kilogram in January 2001 to $163.1 per kilogram (equivalent
to $192.4 per kilogram of uranium) during the week of March 7, 2008, and
expected to remain high, it seems unlikely that production costs will hamper
the future supply of uranium.e
Assuming that the available uranium resources will be adequate, more uranium
production will be needed to ensure the annual delivery of 96,000 metric
tons. In recent years, 40 to 50 percent of the worlds uranium supply has
come from secondary sources, including stockpiles of uranium, reprocessed
spent fuel, and re-enriched depleted uranium tails.f Those secondary sources
are expected to decline over the next 5 years, as the Megatons to Megawatts
program, which converts decommissioned Russian warheads into commercial
fuel, concludes in 2013. Primary production, which provided 40,263 metric
tons of uranium in 2004, will have to be increased further to make up for
diminishing secondary sources and increasing demand.g
The relatively high price of uranium already is leading to increased output.
New mines in Australia, Canada, Kazakhstan, Brazil, and India are expected
to add 30,000 metric tons of production capacity by 2010.h The reference
case used by the World Nuclear Association projects the addition of 30,000
metric tons of supply by 2015, before uranium mining slowly decreases to
90 percent of its peak 2015 level in 2030.i Also, the uranium supply can
be extended further by worldwide recycling of spent fuel and the use of
breeder reactors.
