Nuclear fuel definition

Nuclear fuel definition

The nuclear fuel is the material that has been adapted for use in nuclear power generation.

When it comes to nuclear fuel we can be talking about the same item or set that is made ready it can be used for containing the material itself, but also other elements.

The most widely used process involving the nuclear fission fuel.

There are different types of nuclear fuel, but the most common fuel is consisting of fissile elements such as uranium, generating chain reactions in nuclear reactors. The most common isotope in the fission is uranium-235.

Production processes nuclear fuel forms the set called the nuclear fuel cycle.

Another nuclear process is much less…

Uranium - nuclear fuel

Uranium - nuclear fuel

Uranium is the most commonly used nuclear fuel in nuclear fission reactions. It is a natural element that can be found in nature. However, in order to be able to use uranium in a nuclear reactor it must undergo some treatment.

 

To know the peculiarities that make uranium so different from the other substances we must first consider some basic nuclear physics.

 

Basic physical considerations An atom of a nucleus and of electrons that surround this nucleus. In turn, a nucleus consists of protons and neutrons. A proton has a positive charge. A neutron has no electric charge and is neutral.

 

The positive charges of the protons try to…

Nuclear fusion reactor - ITER Project

Nuclear fusion reactor - ITER Project

The experimental fusion reactor ITER (International Thermonuclear Experimental Reactor) is a large-scale scientific experiment designed to test the feasibility of fusion as an energy source. Currently the ITER fusion reactor is under construction in the south of France, in Cadarache.

At the industry level, nuclear fusion does not exist yet. Since the 50s under investigation on the use of the energy generated in the nuclear fusion of light atoms into heavier. The development of nuclear fusion is considered very important because of the advantage offered by the large amount of energy released in the process and the abundance of deuterium, an isotope of hydrogen suitable for fusion.

What is a nuclear power plant?

What is a nuclear power plant?

A nuclear power plant is a facility for obtaining electrical energy using nuclear energy.

Its operation is similar to that of a thermal power plant or that of a solar thermal plant: from a source of energy thermodynamics is used to obtain heat, with the heat of steam and with the steam to drive a turbine that will generate electricity.

The difference between the different types of electrical installations is that the power source: a nuclear power plant uses the heat released in the nuclear fission reactions of certain atoms, in a thermal power station the heat source (thermal energy) comes from the Combustion of one or more fossil fuels (coal, natural gas, fuel ..). Finally…

Accident of the nuclear power station of Vandellós I

Accident of the nuclear power station of Vandellós I

The nuclear power station of Vandellós I is part of the nuclear complex located next to the population of L'Hospitalet de l'Infant in the province of Tarragona. The complex is formed by the nuclear plants of Vandellós I and Vandellós II. At present, only the Vandellós II nuclear power plant is still operational.

On 19 October 1989, a nuclear accident occurred at the Vandellós I plant.

That day a fire broke out in the electric generator due to a mechanical failure. Indirectly, this fire caused a flood of seawater in the area of the nuclear reactor that caused some of the safety systems to be inoperative.

The Vandellós I Nuclear…

What is an electric generator?

What is an electric generator?

An electric generator is a machine able to transform any type of energy, which can be chemical, mechanical or light, into electricity.

An electrical generator is all that a device capable of maintaining electric potential difference (voltage) between two points, called centers or terminals. Electric power generators are machines designed to transform mechanical energy into electricity.

Operation of an electric generator

The operation of an electric generator is similar to an electric motor running in reverse.

This transformation is achieved by the action of a magnetic field on electrical conductors arranged in coils on armor plates. If mechanically relative movement…

Chinon Nuclear Power Plant

Chinon Nuclear Power Plant

The Chinon nuclear power plant is located in France, near Chinon in the territory of the city of Avoine (Indre-et-Loire) in the Country of Véron. Uses water from the Loire River.

The annual production of the nuclear plant is approximately 24 billion kilowatt-hours per year. This production accounts for approximately 4% of national electricity production in France. 1500 people work in the nuclear power plant.

History of the Chinon nuclear power plant

The Chinon nuclear power plant has two different types of nuclear reactors:

Gas-graphite reactors

Between July 1955 Electricité de France (EDF) controls a nuclear reactor project at the Commissariat for Atomic…

Radioactivity definition

Radioactivity definition

Radioactivity defined as the spontaneous emission of particles (alpha, beta, neutron) or radiation (gamma, K capture), or both at the same time, from the decay of certain nuclides that these particles are, due to an adjustment of their internal structure.

Radioactivity can be natural or artificial. In natural radioactivity, the substance already has radioactivity in the natural state. In artificial radioactivity, the radioactivity has been induced by irradiation.

A radionuclide is all the radioactive cores of the same kind. All radioactive cores forming a radionuclide have a well-defined radioactivity, which is common to all of them and that identifies them; the…

Cattenom I Nuclear Power Plant

Cattenom I Nuclear Power Plant

The Cattenom Nuclear Power Plant is a nuclear power plant located in France. It is currently operated by Electricité de France (EDF). Geographically it is located in Lorraine, in the town of Cattenom, on the Moselle banks between Thionville and Trier. The cities of Luxembourg, Arlon, and Metz are very close to the nuclear power plant.

Luxembourg, Saarland and Belgium demanded closure of the plant. In spite of this, there is a project under way to extend its useful life until 2025.

Characteristics of the Cattenom nuclear power plant

The Cattenom nuclear plant is a nuclear fission power generation facility. It has four nuclear water pressure reactors (PWR). Each of these…

Definition of energy

Definition of energy

Ability of a physical system to produce a job.

This definition, although it is the most widespread, can be misleading because of the vagueness of the term "capacity", and therefore, it is better to define the energy as what, when a work occurs, decreases in an amount equal to the work produced. Energy, then, is measured in the same units as labor.

History of the study of energy

The notion of energy appears for the first time from the investigations of Joule and Carnot on the conversion of heat in mechanical work and thanks to the theory of Helmholtz in which it connects the work done by an isothermal system with the internal energy and the Entropy of this system. In this…

Chemical energy

Chemical energy

Chemical energy is the potential of a chemical to undergo a transformation through a chemical reaction or to transform into other chemicals. Forming or breaking chemical bonds involves energy. This energy can be absorbed or evolved from a chemical system.

The energy that can be released (or absorbed) by a reaction between a set of chemical substances is equal to the difference between the amount of energy of the products and the reactants. This change in energy is called the internal energy of a chemical reaction.

The internal energy change of a process is equal to the change of heat if it is measured under constant volume conditions, as in a calorimeter. However under conditions…
