Introduction

Energy is a very important topic in our days. Especially because all the contamination and the damage that we are causing to the planet, we need to know and develop new methods to obtain energy and that doesn’t hurt the planet so much. Some scientist says that at the steps we are taking theresources of the planet are going to get finished very soon. The other concern of people is the money that they are paying to obtain the services of energy, because if the resources are lower they are going to get more expensive.

That’s the reason why nuclear power has been an alternative solution to this problem, because all the benefits that we can find using it. On the other side it also hasits own problems, that’s why this investigation is going to talk about the nuclear power, how it works and algo their benefits and problems of use this energy source.

Nuclear Power

Nuclear power is generated using Uranium, which is a metal mined in various parts of the world. This produces huge amounts of energy from small amounts of fuel, without the pollution that you'd get from burning fossil fuels.

Sixteen percent of the world's electricity is supplied by nuclear power, according to the World Nuclear Association. The electricity is produced by440 nuclear reactors in 31 countries.
The United States has the most reactors with a total of 104, according to the International Atomic Energy Agency. The reactors are responsible for producing nearly 20 percent of the country's electricity. The country that gets the highest percentage of its electricity from nuclear power is France. Its 59 reactors generate more than 78 percent of itselectricity.

Nuclear power stations work in pretty much the same way as fossil fuel-burning stations, except that a chain reaction inside a nuclear reactor makes the heat instead. The reactor uses Uranium rods as fuel, and the heat is generated by nuclear fission.

Imagine following a volt of electricity back through the wall socket, all the way through miles of power lines to the nuclear reactor thatgenerated it. You'd encounter the generator that produces the spark and the turbine that turns it. Next, you'd find the jet of steam that turns the turbine and finally the radioactive uranium bundle that heats water into steam. Welcome to the nuclear reactor core.

More specifically carbon dioxide gas or water is pumped through the reactor to take the heat away this then heats water to makesteam. The steam drives turbines which drive generators. Modern nuclear power stations use the same type of turbines and generators as conventional power stations.

In Britain, nuclear power stations are often built on the coast, and use sea water for cooling the steam ready to be pumped round again, it also serves for preventing it from overheating and melting down. This means that they don't havethe huge "cooling towers" seen at other power stations.

In March 2011, viewers around the world became well acquainted with this reality as Japanese citizens fled by the tens of thousands from the area surrounding the Fukushima-Daiichi nuclear facility after the most powerful earthquake on record and the ensuing tsunami inflicted serious damage on the plant and several of its reactor units....
