Plutonium

Plutonium

Plutonium is a chemical element, usually of artificial origin, that is used as a nuclear fuel in the manufacture of nuclear weapons.

The symbol of this chemical element is Pu and its atomic number is 94. It is an element that belongs to the series of actinide elements. Plutonium has 16 isotopes, all of them radioactive. The element is a silver metal and has 5 different crystalline structures.

Chemically plutonium is a very active material. It can form compounds with all non-metallic elements, except noble gases. The metal dissolves in acids and reacts with water, although moderately compared to acids.

Although traces can be found in nature, all plutonium…

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.
  • Seawater energy.
  • Biomass energy
  • Geothermal energy.

Nuclear Energy in Industry

Nuclear Energy in Industry

Industry is one of the fields in which nuclear energy is used. The use of nuclear energy in modern industry in developed countries is very important for the improvement of industrial processes, for measurements and automation, and for quality control.

The use of nuclear radiation is applied in a wide range of activities. These activities can be quality control of raw materials of industrial processes (cement, thermal power plants, oil refineries, etc.), or quality control of products manufactured in series. In the case of series production, it is used as a prerequisite for the complete automation of high-speed production lines.

In the field of industry, irradiation…

Scale INES - International Nuclear Event Scale

Scale INES - International Nuclear Event Scale

La escala INES es un instrumento para cuantificar la gravedad de un suceso nuclear y radiológico (ya sean accidentes o incidentes nucleares).

INES son las siglas en inglés de International Nuclear Events Scale (Escala Internacional de Sucesos Nucleares)

The INES scale is used throughout the world to communicate to the public systematic information about the importance of such nuclear and radiological events from the point of view of safety. In the same way that Richter scales are used to quantify the intensity of an earthquake or the Celsius scale to measure temperature, the INES scale indicates the importance of events derived from a wide range…

Antoine-Henri Becquerel

Antoine-Henri Becquerel

Antoine-Henri Becquerel studied at the Polytechnic School. In 1875 he entered the department of bridges and roads, and became chief engineer in 1894. In 1892 he succeeded his father in the chair of the Museum of Natural History, and in 1895 he became professor of the Polytechnic School.

He continued his father's studies, and the discovery of X-rays by Röntgen (1896) made Antoine-Henri Becquerel think that this new radiation could be related to fluorescence and phosphorescence.

Henri Becquerel He also studied the polarization and absorption of light in crystals.

Finally, his experiments with uranium and the radiation it entailed would cause him to die.

Enriched uranium

Enriched uranium

Enriched uranium is uranium that has gone through a technological process to increase the proportion of the uranium-235 isotope. As a result, natural uranium is divided into enriched uranium and depleted uranium.

Natural uranium contains three isotopes of uranium: uranium-238 (99.2745%), uranium-235 (0.72%) and uranium-234 (0.0055%). The isotope uranium-238 is a relatively stable isotope, incapable of an independent nuclear chain reaction, unlike the rare uranium-235. Currently, uranium-235 is the main fissile material in the chain reactions of nuclear reactors and nuclear weapons technologies. However, for many applications, the fraction of…

Disadvantages Of Nuclear Energy

Disadvantages Of Nuclear Energy

At the moment of analyzing the disadvantages of nuclear energy in the first place, it is necessary to consider the different areas in which nuclear energy is used. The main use of nuclear energy is the generation of electricity. Although electricity production is the most controversial nuclear application, nuclear technology is also used in the military, medical or environmental fields, among others.

One of the advantages of nuclear energy is that it reduces the dependence on thermal power plants and, therefore, the consumption of fossil fuels. However, the main source of greenhouse gas generation comes from road transport. That is, the use of…

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.

Despite this, there are other uses of nuclear energy in such important fields as medicine, pest control, etc.

Three Mile Island nuclear power plant, USA

The Three Mile Island nuclear power plant is Troba a l'Illa to the Susquehanna river to the county of Dauphin to Pennsylvania, a deu quilometres to the south-east of Harrisburg ALS Estats Units.

On March 28, 1979, collapse 1 collapse to nuclear reactor number 2, which will be destroyed. Three Mile Island is AIXI IUD because it is Troba to three thousand riu avall from Middletown, Pennsylvania. The nuclear plant will be built originally by General Public Utilities Corporation, later on, with the nou nom of GPU Incorporated.

Chooz Nuclear Power Plant, France

Chooz Nuclear Power Plant, France

The Chooz nuclear power plant is a nuclear power plant in Chooz, France. That is, its function is to harness the nuclear energy of nuclear fission reactions to generate electricity. The nuclear power plant is located in a meander of the Maas. Also, the nuclear facility is located on the Pointe de Givet, about 25 km from the Belgian Dinant.

The first of the two nuclear reactors available to the nuclear plant was built in the 1960s with the participation of Belgian industry. In this way, the location near the French-Belgian border is explained in part.

More than 700 EDF employees work with over 200 subcontractor employees at the Chooz nuclear power plant. During…

Beta Particle

Beta Particle

A beta particle (β) is an electron that shoots out of a radioactive event.

By the law of Fajans, if an atom emits a beta particle, its electric charge increases by a positive unit and the atomic mass number does not change. This is because the mass or mass number only represents the number of protons and neutrons, which in this case the total number is not affected, since a neutron "loses" an electron, but becomes a proton, ie , a neutron becomes a proton and therefore the total number of atomic mass (protons plus neutrons) does not vary.

The interaction of beta particles with matter generally has a 10-fold greater range of action and an ionizing power equal to one…
