Nuclear Energy - Derived from the Atom

The term nuclear comes from the Latin nucleus, which means inner core. Nuclear energy, also known as atomic energy, is released through the disintegration of the nucleus of certain unstable atoms.
To gain stability, unstable atoms are converted into another type of atom, releasing energy in the form of radiation - this is known as radioactivity.
Whether natural or artificial, radioactivity is part of our everyday lives. X-rays, air transport, and high mountains are all areas where we are more or less exposed to it. However, when it comes to producing electricity, safety and security precautions have to be taken to contain the toxic radiation inside the reactor core.
This is even more crucial when you consider that the nuclear power industry is set to grow considerably in the future, because of its capacity to produce carbon-free energy.
Nuclear power
by La Recherche
Every two months, this booklet by La Recherche offers an understanding of the technological, economic and environmental challenges in the energy sector.
Radioactivity and energy
A natural phenomenon, radioactivity takes place inside certain unstable atoms, called radioactive atoms, which disintegrate while emitting several types of radiation.
From uranium to fuel
Uranium occurs naturally in the earth's crust. After extraction, it undergoes a series of transformations to turn it into a fuel that can be used in nuclear power plants.
Inside a reactor
A nuclear power plant uses the energy released through nuclear fusion to produce electricity and great care is taken to contain radioactive materials.
Radioactivity and its effects on the population
When we hear the word radioactivity, we often think of nuclear testing, power plant accidents and radioactive waste. However, radioactivity is a natural phenomenon present everywhere on earth. And most artificial radioactivity emitted by human activity comes from medical uses. What levels of radioactivity are we exposed to on a daily basis? Are there any risks involved? Planète Energies takes a comprehensive look at the issues.
