Various Nuclear Energy Facts

What is nuclear energy?

Nuclear energy refers to the energy that is released during nuclear reactions, either through nuclear fission or nuclear fusion. Nuclear fission occurs when the nucleus of an atom is split into two smaller nuclei, releasing a large amount of energy in the process. On the other hand, nuclear fusion occurs when two atomic nuclei come together to form a larger nucleus, also releasing a significant amount of energy.

Nuclear energy is primarily generated in power plants through the process of nuclear fission. Uranium-235 and plutonium-239 are commonly used as fuel in nuclear reactors. These fuels undergo controlled nuclear fission reactions, releasing a tremendous amount of heat. This heat is then used to produce steam, which drives turbines connected to generators, ultimately generating electricity.

When compared to other forms of energy, nuclear energy has some distinct advantages. Unlike fossil fuels, such as coal and oil, nuclear energy does not produce carbon dioxide emissions, making it a cleaner source of energy. Additionally, nuclear energy is incredibly efficient, as a small amount of fuel can produce a large amount of energy. However, nuclear energy also comes with its own unique set of challenges and concerns, which we will explore later in this article.
