Nuclear reactors can be classified according to different criteria. One of the criteria is the purpose for which they will be used. In this regard we distinguish the types of nuclear reactors used for civilian purposes, for military purposes or for research purposes.
Civil nuclear reactors use nuclear energy to generate power for electricity; military reactors create materials that can be used in nuclear weapons such as the atomic bomb; and research nuclear reactors used to develop weapons or energy production technology, for development purposes, for nuclear physics…
A nuclear reactor is a facility capable of initiating, controlling and maintaining nuclear reactions (usually nuclear fission) in chain that occur in the core of this installation.
The composition of the nuclear reactor is formed by the nuclear fuel, the refrigerant, the control elements, the structural materials and, in the case of a nuclear reactor, the nuclear moderator.
To build a nuclear reactor it is necessary to have enough nuclear fuel, which we call critical mass. Having enough critical mass means having enough fissile…
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…
A boiling water reactor or BWR is a type of nuclear reactor. It is the second type of reactor most used in nuclear power plants in the world. Approximately 22% of the nuclear reactors installed in the different nuclear power plants use the boiling water reactor.
The main function of this type of reactors is their installation in power plants of power for the generation of electricity.
The most important feature of the boiling water reactor (BWR) is the use of pressurized water as a neutron moderator and as a core coolant. Unlike the pressurized water reactor (PWR), it does not…

The pressurized water nuclear reactor is the type of nuclear reactor more used worldwide in the nuclear power plants of generation of electricity. At present, there are more than 230 nuclear reactors in the world made with the pressurized water system. Also known by its abbreviations PW. Its main feature is the use of water under high pressure in the primary circuit to prevent it from boiling.
Within the naval engineering the pressurized water nuclear reactor (PWR) is widely used. In fact, this model was originally designed to be used on a nuclear submarine.
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 to get steam and with the steam to drive a turbine that will generate electricity.
The difference between the different types of electrical installations is in the energy 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…
The moderator is a component that is part of nuclear reactors. It is located in the reactor core. The function of the moderator is to reduce the speed of neutrons in nuclear fission reactions.
During fission nuclear reactions, neutrons collide with fissile atoms (uranium and plutonium) present in the nuclear fuel causing fission. With each fission reaction, one or two neutrons are released at high speed.
The objective to maintain a chain fission reaction is that these neutrons hit other fissile atoms but at such a speed it is very difficult. The objective of…
A coolant in a nuclear reactor is a liquid or gaseous substance that passes through the reactor core and removes heat from the nuclear fission reaction.
In the double-circuit power reactors, the reactor coolant enters the steam generator, which produces steam that drives the turbines, and in the single-circuit reactors the coolant (steam or gas) can serve as the working fluid of the cycle of the turbine. In research (for example, materials science) and special reactors (for example, in reactors for the accumulation of radioactive isotopes) the coolant only cools the reactor, the…
Nowadays, the main use given to nuclear energy is the generation of electric power. Nuclear power plants are responsible of doing this process. Almost all nuclear power plants in production are using nuclear fission since the nuclear fusion, despite being under development, is currently unfeasible.
The operation of a nuclear power plant is identical to the operation of a thermoelectric power plant working with fossil fuels like coal, oil or gas, except in the way of providing heat to the water for converting this one into steam. In nuclear reactors this process of producing heat is made…

What is nuclear energy? Nuclear energy is the internal energy in the atomic nucleus, that is, the central part of an atom. Atoms are the smallest particles in which a material can be divided. The nucleus of an atom is composed of two subparticles: neutrons and protons. These subparticles are held together due to energy links. At the moment in which these bonds are modified, a large amount of thermal energy is released in the form of heat.
Nuclear technology deals with the use of this internal energy for a wide variety of applications. The most well-known…

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…
