The nuclear energy
While demand for energy continues to rise due the continuous need of energy in developing and developed countries and the fast decrease of natural non renewable sources of energy such as oil and gas, many countries face serious challenges regarding the security of their energy supply. As Juan Pablo Perez Alfonzo said “the oil is the evil’s excrement” therefore we can legitimately wonder what is the nuclear energy. For couples decade nuclear energy has been wished-for by some people to be a solution among others in the meantime some other are against this source of energy and fear it. Through this report, I will try to understand where does the nuclear energy come from and is it a non limited resources ? In the second part, I will evaluate the advantages and disadvantages of the nuclear energy then in a third part we will try to understand why in the US, Nuclear energy is such major issue..
What is a nuclear energy?
At the heart of the reactor of a nuclear reaction is fission: a neutron moves and strikes an atom of uranium, and then the nucleus absorbs the neutron. The core becomes so unstable that it bursts. It is divided into two parts and releases energy. Nuclear fission is not possible with any element. It uses uranium as its atoms are large nuclei unstable easy to divide. This reaction causes a release of energy as heat, which will convert water into steam generator. The steam will turn turbines that will create an electric current.
Another reaction is the fusion: A nuclei of hydrogen and helium fuse. These two nuclei are the source of energy from the sun and stars, then their fusion results in a tremendous amount of energy. The
