The creation of a nuclear power plant was a turning point in the history of energy, because a person got the opportunity to get huge energy without using traditional sources of fuel. A nuclear power plant operates on nuclear fuel, therefore, in the process of generating electricity, care must be taken to avoid a possible accident.
Chernobyl NPP
The accident at the Chernobyl nuclear power plant (Chernobyl nuclear power plant), located near the city of the same name in Ukraine, became the largest accident in the history of nuclear energy. It occurred on April 26, 1989. The destruction of the fourth power unit provoked the release of many fission products of nuclear isotopes. The air masses carried them over a considerable distance. Radioactive isotopes were discovered on the border with Russia and Belarus, as well as in several other countries.
The day before the disaster, NPP workers planned to conduct design tests of the safety system of the fourth power unit. During the tests, difficulties arose in connection with the control of the reactor. April 26 at about one in the morning there was a sharp uncontrolled increase in power, due to which the destruction of the fourth power unit occurred.
In the following days, attempts were made to deactivate radioactive isotopes using special substances, but they did not lead to anything. For unknown reasons, the temperature in the reactor shaft began to rise, which provoked an even greater release of radioactive substances into the atmosphere.
More than 8 million people, including residents of Belarus, Russia and Ukraine, were exposed to radiation. Almost 400 thousand inhabitants of the territories adjacent to the Chernobyl nuclear power plant were urgently evacuated. Affected agricultural land.
