After my estimate 25 000 tonnes each year.
Uranium is not used at home.
The majority of nuclear reactors use uranium as nuclear fuel.
The USA has approximately 3% of the world's uranium reserves.
On the basis of December 2012 data Australia has 29% of the world's uranium resources – 1.7 million tonnes of uranium.
approx. 70 tonnes.
USA has uranium from national mines or from imports.
The world production of uranium is approx. 55 000 t each year.But the the production is variable from an year to another.
Uranium-234 has any practical use.
Uranium is an element, it does not 'use' any products.
Coal dont't use uranium ! But coal ashes contain traces of uranium.
Approx. 40 000-50 000 t.
US $ 51,5/lb (at 25.07.2011) or 11,3 USA $ per 100 grams (natural uranium in the form of the unrefined oxide U3O8).
