Nuclear power… An alternative for Mexico?


Is it possible to supply Mexico with electricity through nuclear power? Globally, energy supplies consisted of non-renewable resources, our civilization is based on the use of fossil fuels like oil, coal and gas mostly, and this has started to impact on the climate and also in humans, animals, plants, ecosystems and everything that isabove or below our planet. Mexico seeks to ensure its sustainable development using renewable energy sources that don´t lead to damage to the environment or human health.

Justification of the work

This work is done because of the concern and interest that exists in Mexico to solve energy that does not harm the environment and become more productive. We can´t be left behind, thinking that theirrational use of fossil fuels will help us in search of a better life.

Theoretical framework

To understand what nuclear energy is energy we know, energy is the ability of bodies to produce mechanical work.

The energy is expressed in the physical changes, for example, by raising an object transport, deform or heating. Energy is also present in the chemical changes, such as when a piece ofwood burning or decomposition of water by the electric current.

Strictly speaking, the nuclear energy is the energy released by splitting the nucleus of an atom (nuclear fission) or joining two atoms to become an individual atom (nuclear fusion). In fact comes from nuclear core.

When there is one of two physical reactions (fission or nuclear fusion) atoms experience a slight loss of mass.This lost mass is converted into a large amount of heat energy as Albert Einstein discovered his famous equation E = mc2.

However, often when we talk about nuclear energy, we refer to power generation using nuclear reactions.

The Greek philosopher Democritus of Abdera was the first to give a definition of atom: the smallest constituent of matter. This was in the V century. C. Atom comes fromthe Greek meaning "non-divisible". Although later appeared the concept of nuclear fission that is obtained splitting atoms.

In 1896 the French physicist Antoine Henri Becquerel found that certain substances, such as salts of uranium, produced penetrating radiation of unknown origin. This phenomenon was known as radioactivity.

In late 1938, on the eve of World War II, a team of Germanresearchers at the Kaiser Wilhelm Institute in Berlin, built by Otto Hahn, Fritz Strassmann, Lisa Meitner and Otto Frisch, interpreted the phenomenon of nuclear fission, to by identifying the element barium as a result of excision of the nucleus of uranium.
On December 2, 1942, a group of nuclear physicists in Europe, who emigrated to the United States and led by the Italian physicist Enrico Fermi, putup the first nuclear chain reaction caused by the man with the intention to apply for the first time nuclear energy. The nuclear reactor employee, known as Chicago Pile (CP-1) was a simple structure and is installed under the platform of the football stadium at the University of Chicago. Uranium fuel is used, such as that used in his experiments Fermi in Rome, and graphite moderator.Preparations for this experiment were conducted in great secrecy. The research objective was to obtain a chain-reaction-controlled in principle to allow the study of their properties in view of the possible development of an atomic bomb.

Once removed carefully control rod was initiated chain reaction, thereby entering into the first reactor operating in the world.

The development of nuclear power waspromoted at all times by the interest generated on the production of electricity using this source of energy. Throughout the 60's and 70's, they started several attempts at nuclear programs in various countries.


First the people have to understand that the problem of energy use that causes damage and harm to humans and their environment is something that has been presented...
