Situation of nuclear energy in the world

Situation of nuclear energy 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…

Types of nuclear reactors

We distinguish two types of nuclear reactors

  • Nuclear research reactors. This type of reactors used neutrons generated during nuclear fission reactions to produce radioisotopes that are going to be used in other applications of nuclear energy or materials for studies.
  • Nuclear power reactors. These reactors are based on the use of the thermal energy generated in the fission reactions. The main and most known application of this type of reactor is to generate electricity in nuclear power plants. However, also they are used for desalination…

Fukushima nuclear accident

Fukushima nuclear accident

On March 11, 2011 in Fukushima occurred one of the worst nuclear accidents in history after the Chernobyl nuclear accident.

A 8.9 magnitude earthquake off the northwest coast of Japan and a subsequent tsunami severely affected Dahiichi Fukushima nuclear plant on the northeast coast of Japan.

At the time of the nuclear accident at the Fukushima reactors had 6. Reactors 1, 2 and 3 were operating while nuclear reactors 4, 5 and 6 were unemployed for maintenance.

After the earthquake Fukushima reactors that were still running is automatically stopped. To cool the reactors,…

Pressurized Water Reactors

Pressurized Water Reactors

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.

Nuclear reactor

Nuclear reactor

A nuclear reactor is an installation capable of initiating, controlling and maintaining nuclear reactions (usually nuclear fission) chain that occur in the core of this facility.

The composition of the nuclear reactor is formed by the nuclear fuel, coolant, control elements, structural materials and, in the case in question a thermal nuclear reactor, the moderator.

Nuclear reactors can be classified as thermal reactors and fast reactors.

Thermal reactors are those which function by delaying (moderating) the fastest neutrons or increasing the proportion of fissile atoms.…

Boiling water nuclear reactor

Boiling water nuclear reactor

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…

Operation of a nuclear power plant

Operation of a nuclear power plant

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 operating with 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 by the fission…

History of nuclear energy

History of nuclear energy

To explain the history of nuclear energy we could distinguish three major stages:

  • Physical and chemical scientific studies of the elements.
  • The development of the nuclear bomb during World War II.
  • Use of nuclear energy in the civil field.

Scientific studies cover this whole period since the first Greek philosophers began to define atoms, until the development of the first nuclear bomb. In this process, different scientists discover the presence of electrons, neutrons and protons and properties that make one atom more radioactive than another.
