HOW DOES IT WORKS ?







All starts in the nuclear reactor there carry out uranium fission, that makes a lot of energy.
This energy warm out water that spread to the vapour generator.


One of the first uses that is given to nuclear energy is that of electric power generation. But what is nuclear energy, is the internal energy contained in the nucleus of an atom. This energy can be expelled in the form of calorific energy: fission or fusion. 

Worldwide, 90% of nuclear power reactors, that is, reactors destined for the production of electric energy are light water reactors (in the versions of pressurized water or boiling water). In nuclear engineering, light water is called running water


To operate a nuclear power plant, a wide variety of types of nuclear reactors are available. However, all types of nuclear reactors have the same objective: to use heat from nuclear fission reactions to drive the turbines that will generate electricity.

The basic principle of the operation of a nuclear power plant with a pressurized water reactor can be simplified in these 4 steps:

1. Obtaining thermal energy by nuclear fission of the nucleus of atoms

2. Generate water vapor using the thermal energy previously obtained in the heat generator.

3. Actuate a set of turbines using the steam obtained.

4. Use the mechanical energy of the turbines to drive an electric generator. This electric generator will generate electricity.
