Definitions about Nuclear Energy

Definitions and concepts that will help a better understanding of the articles exposed on this website.

The majority of terms are directly related to nuclear energy, but there are also other concepts related to physics that complement the explanations of the website.

Neutron
A neutron is a subatomic particle contained in the atomic nucleus. It has no net electric charge, as opposed to positive electric charge of the proton.

Neutron moderator
Neutron moderator is an element to slow dwon the neutrons in a nuclear fission reaction chain. Neutron moderator is an element to slow dwon the neutrons in a nuclear fission reaction chain.
Nuclear fuel
Nuclear fuel is a material that has been adapted for use in nuclear power generation. Nuclear fuel is a material that has been adapted for use in nuclear power generation.

A nuclear power plant is a facility for obtaining electrical energy using nuclear fission reactions. Nuclear energy is used to produce heat. A nuclear power plant is a facility for obtaining electrical energy using nuclear fission reactions. Nuclear energy is used to produce heat.
Potential energy
Potential energy is the energy that an object possesses due to its position in a force field or that a system has due to the configuration of its parts Potential energy is the energy that an object possesses due to its position in a force field or that a system has due to the configuration of its parts
Proton
A proton is a positively charged particle that lies within the atomic nucleus. The number of protons in the atomic nucleus determines the atomic number of an element.

Radionuclide
A radioactive nuclide radionuclides or radionuclide is an unstable nuclide and thus degenerates emitting ionizing radiation. A radioactive nuclide radionuclides or radionuclide is an unstable nuclide and thus degenerates emitting ionizing radiation.
Sievert
Sievert is a measure of the effect on health of low levels of ionizing radiation in the human body. Sievert is a measure of the effect on health of low levels of ionizing radiation in the human body.
Steam turbine
A steam turbine is a mechanical device that transforms the thermal energy contained in the steam under pressure into rotating mechanical energy. In the turbine, the internal energy of the steam is transformed into mechanical energy.

Thermodynamics
Thermodynamics is the branch of classical physics that studies the thermodynamic transformations induced by heat and work in a system. Thermodynamics is the branch of classical physics that studies the thermodynamic transformations induced by heat and work in a system.
Watt
The watt is the international standard power unit in SI. It is the unit that measures the energy conversion rate (joules) divided by seconds. The watt symbol is represented by the letter W.
