After the data known today, approx. 4 % from the world uranium reserves (approx. 225 000 tonnes).
Probably approx. 5.109 t (in the crust earth and in the seas and oceans).
Probably 40 000 t each year.
not enough
It depends upon the amount of uranium being used.However, the energy given out per nucleon per fission of uranium is 0.9 MeV.
Probably approx. 40 kg of enriched uranium.
7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium).
The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.
92 protonsAll the isotopes of uranium has 92 protons.
On the basis of December 2012 data Australia has 29% of the world's uranium resources – 1.7 million tonnes of uranium.
The world production of uranium is approx. 55 000 t each year.But the the production is variable from an year to another.
Approx. 90 % in 2010.
Approx. 5 % of the world reserves.
Around the world approx. 55 000 t uranium are yearly produced.If you want a mean this is 150 t/day.
Uranium is formed in the world by stellar nucleosynyhesis.
uranium and plutonium are much more costly minerals.
Now Kazakhstan is the biggest producer of uranium in the world.
None. A pellet of uranium contains uranium, not coal.
Yes, uranium is extracted from mines.Many uranium mines exist around the world.
The largest reserves of uranium are in Australia.
The world production of uranium was approx. 55 000 t.
