The main sources of power in Ukraine

There are a few different types of sources of power in Ukraine.Among them are hydro power plants,heat power stations and nuclear power stations.

Ukraine is heavily dependent on nuclear energy.It has 5 nuclear power station with 15 nuclear reactors which generate about half country’s electricity.20% of the total energy produced by the country is exported to neighboring countries.

Uranium and coal for the fuelling of nuclear stations is mind by Ukraine itself and it imports oil and gas from Russia,as well as the main equipment for reactors.Nuclear energy development started in 1970 with construction of the Chernobyl power plant which was considered to be the biggest of all stations in Ukraine.Nowadays Rivno power station is in the first place of the largest nuclear station in the country.

Nuclear power is,probably,the easiest method of energy production and have many advantages.The amount of energy that forms during the burning of 1 kilo of uranium is equal to that of 2500 kilo of coal.20-30 tones of nuclear fuel,that is concentrated and transportable,works for several years.Nuclear plants can be build in any place where they are required to be.The construction of the station is as cheap as electricity itself.The process of electricity generation is not accompanied by environmental pollution.

Despite being the quickest way of extracting energy nuclear stations have negative impact on their surrounding,for example the emission of deadly radiation into atmosphere as result of breakdowns,as happened in 1986 at unit 4 of the Chernobyl power station.
