NUCLEAR POWER:
Strictly speaking, nuclear energy is the energy released by splitting the nucleusof an atom (fission) or when two atoms join to become a single atom (nuclear fusion). In fact, nuclear comes from nucleus.
When a physical reactions of these two (nuclear fission or fusion) atomsexperience a slight loss of mass. This lost mass becomes a large amount of heat energy as Albert Einstein discovered his famous equation E = m·c2.
But often, when talking about nuclear energy, it isreferring to electricity generation using nuclear reactions.
It should be kept in mind that although the production of electricity is the most common utility, nuclear energy can be applied in many othersectors, such as in medical, environmental and military.
In the usual nuclear the reactor core is placed inside a giant steel vessel designed so that if an accident happens to avoid radiation toleave into the environment. This vessel along with the steam generator are located in a building constructed with heavy security with reinforced concrete walls of one to two meters thick designed towithstand earthquakes, hurricanes and even aircraft crashes collided against him.
In 1956 was put in place in England the first nuclear power plant generating electricity for commercial use.
Worldwide,a total of 437 nuclear reactors operating in plants are distrivuted in 30 countries, according to the latest annual report of the International Atomic Energy Agency (IAEA).

In the document, whose data are updated to January 1, 2010, figures that the total power generation of these reactors is 370,187 megawatt. In addition, another 55 reactors, with acombined potential of 50,855 megawatts were under construction in 2009.
The country with the largest number of reactors is the United States (104), followed by France (59) and Japan (54). Then Russia...
