Nuclear energy


The atoms are small particles found in the molecules forming gases , liquids and solids . Atoms themselves are made up of three particles called protons , neutrons, and electrons . An atom has a nucleus that contains protons and neutrons, which is surrounded by electrons. Protons have a positive electrical charge and electrons have a negative electrical charge . Neutrons have no electrical charge. Huge energy is present in the linksthat hold the nucleus together and is released when those bonds are broken . Links can be broken by nuclear fission , and this energy can be used to produce electricity . It is from them that we obtain nuclear energy .


What is the nuclear energy?

Nuclear power is the energy that is contained in the nucleus of the atom , which are the particles more small in which can split an element chemical maintaining its properties .

Characteristics of nuclear energy

The main characteristics of nuclear energy are the following:

  • Nuclear energy is contained in the nucleus of the atom .
  • This type of nuclear energy can be used to produce electricity .
  • It is a very powerful , effective and risky type of energy .
  • It is considered as an achievement of man’s dominance over physics .
  • It can be used in vehicles and to propel submarines .
  • Reactions can occur spontaneously and can also be produced by humans .

What is it for

Nuclear energy is a type of energy that is used for the production of electrical energy mainly . It also has other uses: used to use radiation for the preservation of food , to increase their consumption period and to reduce the losses by insect pests on crops. The radio isotopic techniques that are used also serve to mutate some plants and thus obtain varieties of agricultural crops . It is also used in the area of medicine mainly with the use of isotopes.radioactive such as nuclear radiation that works for prevention , diagnosis , therapy and medical research .


The development of the history of nuclear energy can be divided into three important stages . The first was based on a series of physical and chemical scientific studies of the elements , the second was the development of the nuclear bomb during World War II and finally the use of nuclear energy in the civil sphere . It was a period that was characterized by great scientific studies and with a great participation of important scientists.

The first major scientist to define the atom was Democritus , then John Dalton claimed that the elements were put together to produce combinations of atoms . JJ Thompson was the one who discovered the electron and later, Antoine-Henri Becquerel , verified that uranium produced radiation of unknown origin, which today we know as radioactivity . At the end of World War II, nuclear fission was interpreted .

Where is it obtained from

Nuclear power is obtained from the manipulation of the internal structure with the atoms by fission or fusion . In a fission reaction, the nucleus of a heavy atom , such as uranium , breaks, releasing a small amount of heat . Some of the fragments interact with other uranium atoms causing new fissions forming a reaction in chain . The amount of uranium atoms in a bar of fuel generates enough heat toheat a large amount of water . Then the process is the same as in a thermal power plant, making the water vapor move a turbine that, when connected to a generator, produces electrical energy .

How to get nuclear energy

Nuclear energy is released during the fusion or fission process that occurs in the nucleus as a product of a nuclear reaction . This is the cheapest type of energy to manufacture but carries with it a lot of risks . Nuclear energy is produced through fission, a process in which an atom is taken and divided into equal parts , which makes the mass infinitely less than usual. Also, it can be obtained by means of fusion although both are totally different processes. The nuclear fusionIt works when two atomic nuclei are joined in the same way, which are generally light and are accompanied by the emission of particles .

How does it work

The main use that is given to nuclear energy is in the generation of electrical energy . This occurs in a nuclear power plant , plants that use nuclear fission and fusion to carry out the process. The operation of this plant is the same as a thermal plant that uses coal, oil or gas. The nuclear reactors are responsible for obtaining heat through fission reactions and in other cases by the burning of one or more fuels fossils . These reactors can be of two types: the nuclear reactor that works with waterto pressure and nuclear reactor operated with water at boiling .


The advantages of the use of nuclear energy are the following:

  • It guarantees the supply of electricity as it is available 24 hours a day for a whole year, thus ensuring the adequate supply of electricity.
  • It is a type of energy that is considered clean and that also does not produce CO2. This type of energy does not produce particles that pollute the environment or the atmosphere and for this reason it is considered an ally to avoid climate change .
  • It is considered one of the sources more economical to produce electricity .
  • The discharges that are caused by the production of nuclear energy abroad are minimal since most of the remains are expelled in the form of gas through the chimney .
  • They are an important source of employment and wealth for the area where it is located.


Among its disadvantages we can mention:

  • The uranium needed to produce nuclear energy is not considered a renewable resource .
  • By itself it is not an alternative to fuels that are based on oil, gas and coal.
  • The creation and construction of the nucleated plants includes a huge expenditure of money .
  • It is a type of energy that is completely dependent on fossil fuels.
  • The mining , uranium needed to get to work is an activity considered dangerous for the environment .
  • Despite the fact that nuclear plants are built with important security measures , it cannot be 100% assured that they are safe and atomic energy therefore represents a danger to health and to populations.
  • On some occasions it could be used for war purposes .


The main importance of nuclear energy is its ability to create electrical energy at a fairly low cost. In addition, it intervenes in a positive way with the environment and with climate change since its emissions do not affect the environment nor do they cause damage to the ozone layer .

Use of nuclear energy by country


The country possesses nuclear facilities and also a central storage of waste radioactive. Spain has an important industry on the subject, highly trained, expert and full of adequate technology to produce electricity . In addition, it exports products and services to other places.


The country’s interest in the production of nuclear energy grew in 1956 with the creation of the National Nuclear Energy Commission, which is in charge of all nuclear activities in the country. The government of the nation aims to produce nuclear power to reduce dependence on the natural gas and reduce emissions of carbon dioxide .


In this country it is an alternative although the production project has not yet entered into force. It began its process in 1955 and the country already has nuclear reactors for researching energy production.
