Тhe objects that surround us are made up of invisible particles called molecules.
Тhey in turn consist of particles called atoms. Аt the center of each atom is a nucleus and electrons that revolve around it.
Тhe atomic nucleus is made up of protons and neutrons.
Тhe fission of the nucleus of atoms of certain chemical elements,
such as uranium, as a result of the successive fission of the nuclei of atoms under the influence of neutrons,
emits a huge amount of heat.
The reactor is the main part of the nuclear power plant, where the fission of fuel nuclei creates heat.
The world's most common type of reactor is the so-called "water-water energetic reactor" - VVER.
Number of operable nuclear reactors worldwide, 2021

Some types of resources can be regenerated
relatively quickly in nature, so they are called renewable:
wood and other biofuels. Resources that do not have
this quality are called non-renewable: coal, oil, natural gas,
uranium ore. Solar, wind and tidal energy are among the
inexhaustible renewable energy resources
