What is nuclear power?
Everything in this world consists of very, very small particles, called atoms. Atomic power occurs by splitting the atoms into the metal uranium. When the core of a uranium atom is broken, heat is generated. In scientific language, the process of fission is called. Snippets from the cleaved nuclear nuclei, called neutrons, hit neighboring neighbors so that they are also broken, causing a nuclear reaction. The result is energy that is used in power plants in power plants.
What can nuclear power be used for?
Atomic power can be used for both peaceful and warlike purposes. The energy of an atom can be released in two ways:
In a nuclear reactor’s relatively quiet and controlled energy stream, electricity generates through the cleavage of uranium
In a nuclear bomb’s violent and sudden explosion, resulting from the cleavage of plutonium, which is not found in nature but which is one of the end products of the cleavage of uranium.
The world first gained knowledge of nuclear power in 1945 when the US at the end of World War II threw two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The more peaceful use of nuclear energy was initiated in 1951 when the nuclear energy of a reactor in Idaho Falls, USA, got so much control that it could generate electricity. In 1956, the world’s first nuclear power plant, which was to supply electricity for general use, was the light of day, at Calder Hall in England. The reason why the countries were interested in a-force at the time was, among other things, that it had plutonium as a final product.
What was the attitude of nuclear power before the Chernobyl accident?
Throughout the 1970s and 80’s, many Western countries – such as the US and the Soviet Union – conducted a larger number of nuclear reactors. At that time, it was thought that nuclear power would be cheaper than the traditional energy sources of oil and coal. At the same time, it was convinced of the security of nuclear power plants despite the fact that several major and minor nuclear accidents had taken place in, for example, the Soviet Union and the United States – for example, at Tremileøen’s nuclear power plant in Pennsylvania in 1979. According to the Chernobyl April 26, 1986, the nuclear power- (See sources) bad to share experiences. The background to the fact that information about nuclear accidents was often not published was that, due to the Cold War, great secrecy was heard about the part of the facilities where nuclear weapons were produced.
What is the Chernobyl work?
Chernobyl is a city in Ukraine, formerly part of the Soviet Union, and at the same time it is the name of a nuclear power plant located in the city of Pripjat, 18 kilometers northwest of Chernobyl, near the Belarussian border. Work at the Chernobyl plant was initiated in 1972. The plant consists of four nuclear reactors that can emit heat and generators that can generate electricity. Together they form the main components of a nuclear power plant. Reactor number four in the Chernobyl power plant, a ‘light-water cooled graphite-modulated reactor’, is a reactor type that was only known in the then Soviet Union. In this reactor type, the released neutrons at the release of uranium-235 nuclear nuclei are degraded (moderated) of graphite to maintain the nuclear reaction. The heat produced by nuclear nuclear fission in this type of reactor is used to generate power. The power drives the generator’s turbines, thus creating electricity. Before the nuclear accident in 1986, the Chernobyl plant’s four reactors covered, according to the website www.chernobyl.info (see sources), one tenth of Ukraine’s total electricity needs. Behind the website is the Swiss International Cooperation Agency, the Chancellor of the Chernobyl Program, the SDC (Swiss Agency for Development and Cooperation), which aims to reduce the impact of the accident on people in Belarus, Ukraine and Russia, and partly to create knowledge and international attention to the problems.
As a curiosum, Chernobyl means wormwood, which is a spicy and bitter herb. If something is veiled or bad, it is said that ‘there has been wormwood in the cup’.
How many nuclear power plants exist today?
In 2005, there were a total of 441 nuclear power stations worldwide. These stations produce 16 percent of the world’s electricity. In France, for example, about 80 percent of the electrical energy comes from nuclear energy, and in Switzerland it is about 40 percent. Of the 441 stations, 291 have been in use for 20 years or more, and 90 stations have been in use for 30 years or more.
Update: As of April 2017, 30 countries worldwide are operating 449 nuclear reactors for electricity generation and 60 new nuclear plants are under construction in 15 countries. Acording to NEI NUCLEAR ENERGY INSTTUTE.
There are a total of 16 Chernobyl-type reactors: 15 in Russia and 1 in Lithuania. In addition, one is being built in Russia with the support of Euratom loans.
