Types Of Nuclear Reactors

Types Of Nuclear Reactors

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…

Nuclear Reactor

Nuclear Reactor

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…

Neutron moderator

Neutron moderator

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…

The nuclear power plant Angra is one of the few nuclear plants in Brazil. The plant is located in Angra Nuclear Power Plant (CNAAA) in Playa Itaorna in Angra dos Reis, Rio de Janeiro, Brazil.

This is two nuclear pressurized water reactors

  • The nuclear reactor Angra 1 has a net power of 637 MWe, connected to the electricity grid for the first time in 1985.
  • The nuclear reactor Angra 2 has a net capacity of 1,350 MWe, I connectado to the electricity grid in 2000.
  • It is working on a third reactor, Angra 3, which will have an estimated capacity of 1,405 MWe.…

Atomic Energy

Atomic Energy

Atomic energy comes from the atom, it is the energy that holds together neutrons and protons of the nuclei of atoms. It is also known how nuclear energy, which comes from the nucleus. The name nuclear energy is used because most of the energy of an atom resides in its nucleus.

Two parts of the atom, the nucleus and the crust are differentiated. In the cortex, an indeterminate number of electrons orbit around the nucleus. The nucleus is composed of an indeterminate number of neutrons and protons. The amount of protons in the nucleus will determine the element that the atom is treated,…

Nuclear Power in Brazil

Nuclear Power in Brazil

In 2016, gross electricity production in Brazil was 579 TWh, including 381 TWh (66%) of hydroelectric power, 56 TWh (10%) of gas, 51 TWh (9%) of biomass and waste, 34 TWh ( 6%) of wind energy and solar energy, 26 TWh (4%) of coal, 16 TWh (3%) of nuclear and 15 TWh (3%) of oil.

The high dependence on hydroelectric energy leads to a certain climate vulnerability that is driving the policy to reduce dependence on it.

Around 40% of Brazil's electricity is produced by the national system of Eletrobrás a. About 20% of electricity comes from public utilities, and the rest comes…

Atomic bomb

The operation of an atomic bomb is similar to the operation of a nuclear reactor, wherein the mass of fuel is well above the critical mass. Initially, the fuel is fragmented, and each of the pieces, enough from the others, so it untreated the critical size; Explosion occurs at closer fragments including sharply.

To increase the performance and efficiency of an atomic bomb to be used practically pure fuels; those used so far have been uranium-235 and plutonium-239. Uranium-235 is difficult and expensive to obtain, because it is not possible to chemically separate it from natural uranium…

Nuclear Power in India

Nuclear Power in India

Nuclear power in India is currently in a state of growth with strong nuclear development plans. By 2020, India has set a target to supply 14,600 MW to the grid through the use of nuclear energy. Subsequently, in 2050, India wants 25% of electricity is produced by nuclear energy.

India is a founding member of the global nuclear watchdog, the International Atomic Energy Agency in Vienna.

Because of these restrictions on trade and the lack of indigenous uranium, only India has been developing a nuclear fuel cycle to exploit its reserves of thorium.

Nuclear power plant of Vandellós I

Nuclear power plant of Vandellós I

The Vandellós I nuclear power plant is a graphite-gas nuclear power plant that began operating in 1972. It was part of the group of first generation nuclear power plants in Spain, formed by the Zorita nuclear power plant, Santa Mª de Garoña and the Vandellós I nuclear power plant. It was owned by the Spanish-French company HIFRENSA (Hispano-Francesa de Electricidad).

The nuclear power plant had 480 megawatts (MW) of power. So far the Spanish nuclear power plants were refrigerated and moderated by water. The Vandellós plant, on the other hand, was cooled by gas and its nuclear reaction…
