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…
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,…
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.…
Mexico is rich in hydrocarbon resources and is a net exporter of energy. Country's interest in nuclear energy is based on the need to reduce their dependence on these sources of energy. In recent years, Mexico's energy is increasingly dependent on natural gas.
The energy growth was very rapid in the 1990s, but then stabilized for a few years. Since 2007 expected new growth in demand for electricity to an average rate of almost 6% per year. In 2007, we generated 257 million kWh. Supply Origin is varied electric, gas 126 TWh (49%), oil of 52 TWh (20%), coal 32 TWh (12.5%) and hydroelectric…
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.
Plans to boost nuclear power…
Plutonium is a chemical element with symbol Pu and atomic number 94 which belongs to the actinide series of elements. Plutonium has 16 isotopes, all radioactive. The element is a silvery metal and has 5 different crystal structures.
Chemically plutonium is a very active material. You can form compounds with all nonmetals except the noble gases. The metal dissolves in acidic and reacts with water, but only moderately in comparison with the acid.
While you can find traces in nature, all isotopes of plutonium are of artificial origin. Radioactivity plutonium
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
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.…
The Bruce Nuclear Generating Station is located in Tiverton, Ontario, Canada. The facility is located in the geographical area of Bruce County, hence its name. It occupies an area of 932 hectares.
The nuclear plant was built in stages between 1970-1987 by the provincial Crown corporation, Ontario Hydro. It was not until May 2001 that the Bruce Nuclear Generating Station began operation. Currently, 3,800 employees work at the plant. Chronology
The initial operating license is 18 years, expiring in 2019, but there is an option to extend up to 25 years until 2044.
Gravelines nuclear power station in France, is the sixth nuclear power plant in the world. In Europe alone Zaporizhia nuclear power plant (in Ukraine) surpasses it.
The nuclear plant is located next to the North Sea near the community of Gravelines in northern France, 20 km from Calais. The surface of the core is 150 hectares.
In this section we analyze the advantages and disadvantages of nuclear power. Nevertheless, most organizations related to nuclear energy are already positioned for or against the use of nuclear power. On this site we try to make an objective analysis about this question, giving all the relevant information and offering a space for different conclusions. Advantages of nuclear power
The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels (coal and oil). Less use of fossil fuels means lowering…
