Nuclear Energy Situation in the World

Nuclear Energy Situation in the World

Nuclear energy began to develop during the first decade of 1940. Initially, the research was aimed at the development and production of the atomic bomb. Subsequently, research began on other applications of nuclear energy; the investigation focused on the peaceful use of nuclear energy.

Currently, there are 30 countries in the world that have nuclear power plants for the generation of electricity. In any case, the number of countries that take advantage of nuclear energy is much greater since countries such as Denmark and Italy, which do not have any nuclear facilities, obtain about…

Nuclear Power in France

Nuclear Power in France

In 1974 the French government made the decision to rapidly expand the nuclear power production capacity in France just after the first oil crisis. This decision was made in the context of a France with substantial competence in engineering, but with few autochthonous energy resources. Nuclear energy, with the cost of fuel is a relatively small part of the total cost, in this sense a reduction in imports was achieved and greater energy security was achieved.

As a result of the 1974 decision, France currently has a significant level of energy independence and almost the lowest…

Electric power

Electric power

We define electricity as the form of energy that results from the existence of a potential difference between two points. When these two points are put in contact by means of an electrical conductor we obtain an electric current.

In physics, the electric potential energy, also called electrostatic potential energy, is the potential energy of the electrostatic field. This is an energy that has an electrical charge distribution, and is linked to the force exerted by the field generated by the distribution itself. Together with magnetic energy, the electric potential energy constitutes…

Renewable Energy

Renewable Energy

Renewable energies are those energies that use an energy or fuel source that is considered inexhaustible or that can be regenerated at the same rate at which it is consumed.

Nuclear energy is not considered a renewable energy source since the fuel used, uranium is not limited. The consumption of nuclear fuel is higher than the generation of natural uranium.

The classification of renewable energies depends on the natural resources that are used. Among them we highlight:

  • Solar photovoltaic and thermal energy.
  • Wind power.
  • Hydraulic energy.

Advantages Of Nuclear Energy

Advantages Of Nuclear Energy

The use of nuclear energy involves some controversy. The main disadvantages of nuclear energy are widely known, especially those related to environmental pollution problems in the event of nuclear incidents or accidents.

However, the advantages of nuclear energy are important enough to keep this technology active. The main use of this technology based on the manipulation of atoms is the generation of electrical energy, which is considered a form of non-renewable energy.

Nuclear Power in Chile

Nuclear Power in Chile

During the 70s and 80s Chile was in the process of modernizing the electric sector. During these years Chile liberalized its economy, privatized utility companies and opened the electricity sector to foreign investors.

During this time, however, Chile did not initiate any nuclear energy program unlike Argentina and Brazil. Chile did not seem willing to consider a nuclear energy option. Even in 2005, the future president Michelle Bachelet did not want to incorporate the development of nuclear energy as a valid option as part of her national energy policy.

Nuclear Moratorium in Spain

Nuclear Moratorium in Spain

The nuclear moratorium is the temporary suspension of the construction and start-up of nuclear power plants.

In 1983 in Spain a National Energy Plan was drafted in which a nuclear moratorium would be decreed in the country. The nuclear moratorium involved the blocking of 5 nuclear power plant projects out of the 7 that had been approved. Technically it was a brake on the dynamics of the development of nuclear energy in the country.

What reasons caused the nuclear motive?

There are several reasons that motivated the creation of the nuclear moratorium:

Nuclear Fusion

Nuclear Fusion

Nuclear fusion is a nuclear reaction through which two light nuclei of atoms, usually hydrogen and its isotopes (deuterium and tritium), are combined forming a heavier nucleus. This binding is usually accompanied by the emission of particles (in case of deuterium nuclei one neutron is emitted). This nuclear fusion reaction releases or absorbs a lot of energy in the form of gamma rays and kinetic energy of the emitted particles.This large amount of energy transforms matter to a plasma state.

The nuclear fusion reactions can emit or absorb…
