Nuclear Power Stations is the engines that generated Power supply using Uranium, which is a metal mined in various parts of the world.
Nuclear power produces around 11% of the world's energy needs, and produces huge amounts of energy from small amounts of fuel, without the pollution that you'd get from burning fossil fuels]
How it works:
The main bit to remember:
Question 2:
Mention the Advantages and disadvantages of having power of station..
Advantages
Nuclear power costs about the same as coal, so it's not expensive to make.
Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.
Produces huge amounts of energy from small amounts of fuel.
Produces small amounts of waste.
Nuclear power is reliable.
Disadvantages
Although not much waste is produced, it is very, very dangerous.
It must be sealed up and buried for many thousands of years to allow the radioactivity to die away.
For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult.
Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster.
People are increasingly concerned about this - in the 1990's nuclear power was the fastest-growing source of power in much of the world. In 2005 it was the second slowest-growing.

A cobbler repairs shoes, so if you have enough leather to cobble an animal with four feet or that doesn't need shoes, you have a surplus.
