Energy, Carbon Concerns Put Spotlight on Uranium
INTERNATIONAL: December 11, 2007
The spot price of uranium, used to fuel nuclear reactors worldwide, is
trading at US$93 per pound on Monday, according to Ux Consulting.
The price has come off due to a seasonal slowdown and inventory de-stocking
after hitting a record high of US$136 in June. The price has risen from US$7
in 2000 as nuclear power is back in the spotlight in times of heightened
concern about security of energy supply.
The industry is also back in focus as fear of climate change has helped to
overcome years of opposition to nuclear power after the 1986 Chernobyl
disaster in Russia.
NUCLEAR POWER
The first commercial nuclear power plants started operation in the 1950s and
today there are 439 stations accounting for 16 percent, or 2,658 billion
kWh, of global energy consumption.
In the OECD, the total fuel costs of a nuclear power plant are typically
about one third of those for a coal-fired plant.
However, nuclear plants require large initial capital investments.
FROM ORE TO ENERGY
Uranium ore is mined and purified at the mine site. The end product of the
mining and milling stages is uranium oxide concentrate (U3O8) and this is
the form in which it is sold.
Ore concentrate, or yellow cake, is then chemically converted into uranium
hexafluoride (UF6), a gas which is transported to enrichment plants.
Once the concentration of U-235 reaches 3 to 5 percent, from 0.7 percent in
natural uranium, it is possible to use the converted uranium pellets in
power stations where fission releases thermal energy necessary for
electricity generation.
When the fuel has been in the reactor for about three years, it is removed
and stored.
URANIUM SUPPLY
Production of U3O8 in 2006 was 46,499 tonnes or about 70 percent of
utilities' annual requirements. The rest, around 20,000 tonnes, came from
secondary supplies such as utility stockpiles, recycled uranium from spent
fuel and scrapped atomic weapons.
In 2006, Canada supplied world markets with one quarter of world uranium
production and Australia produced some 20 percent.
The other top 10 producers were Kazakhstan, Niger, Russia, Namibia,
Uzbekistan, the US, Ukraine and China.
It is estimated that Australia has about 24 percent of the world's low-cost
recoverable uranium deposits, Kazakhstan holds 17 percent and Canada around
9 percent.
URANIUM DEMAND
Uranium demand in 2006 was 64,181 tonnes and is estimated at 64,375 in 2007.
The world's measured resources of uranium (4.7 million tonnes), in the cost
category around the current spot price and used only in conventional
reactors, are enough to last for some 70 years.
There are some 439 reactors operating, another 33 are under construction, 94
are planned (mostly expected to be in operation within 8 years) and 222 more
are proposed.
The WNA estimates demand to reach 109,000 tonnes by 2030 in their reference
scenario and in the upper scenario 149,000.
URANIUM PRICE
The increased interest in uranium prompted the New York Mercantile Exchange
(NYMEX) to launch a five-year futures contract together with Ux Consulting
Company (UxC) in May.
Before this contract there was no formal exchange for uranium and price
indicators have therefore been developed by a small number of private
business organisations, such as UxC.
Around 85 percent of all uranium is sold under long-term contracts, ranging
from two to 10 years and the rest, some 20,000 to 30,000 million pounds, are
sold on the spot market.
