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…

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.…

Chernobyl nuclear accident

Chernobyl nuclear accident

The nuclear accident in Chernobyl (1986) is by far the most serious nuclear accident in the history of nuclear energy. It was classified as level 7 (severe nuclear accident) of the INES scale, the highest value. Although it is the same level at the Fukushima nuclear accident was classified, the consequences of the Chernobyl accident were still far worse.

The Chernobyl nuclear power plant is located near the town of Prypyat, 18km from the city of Chernobyl.

At the time of the Chernobyl nuclear power plant accident provided 4 reactors in operation and two more were under construction.

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.

Pressurized water…

Nuclear Power Plant - What is it?

Nuclear Power Plant - What is it?

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…

Boiling Water Reactor

Boiling Water Reactor

A boiling water reactor or BWR (the English boiling water reactor) is a type of nuclear reactor. It is the second most widely used type of reactor 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 most important feature of the Boiling Water Reactor (BWR) is to use pressurized water as a moderator for neutrons and as a core refrigerant. Unlike the pressurized water reactor (PWR), there is no steam generator.

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…

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


 Bugey-2 nuclear power plant, France

The Bugey nuclear power plant is a facility generating electricity consists of 5 nuclear reactors. 4 delos plant reactors are still in operation. The reactor of Unit 1 was closed on 27 May 1994 and currently is in the process of dismantling.

The nuclear plant is located in Bugey, France in Saint-Vulbas community, 65 km from the border of Switzerland. The plant was built…

Doel Nuclear Power Station - 3

The Doel nuclear power plant (in Dutch: Kerncentrale Doel) is in the territory of Doel (the municipality of Beveren), on the left bank of the Scheldt in Belgium. It is located 25 km north of Antwerp, 42 km north-west of Brussels and 136 km south-southeast of Amsterdam (line all distances).

The nuclear power plant is operated by Electrabel operator. Has a layout of four pressurized water reactors (PWR) Westinghouse (Doel 1, 2 and 3) and Framatome / AREVA (Doel 4)

  • Doel 1 412 MWe, commissioned in 1974 for 40 years.
