Nuclear energy.

  1. the energy released during nuclear fission or fusion, especially when used to generate electricity.

  2. Nuclear energy regarded as a source of power. Also called atomic energy.

the energy released by a nuclear reaction, especially by fission or fusion. Practically speaking, nuclear energy uses fuel made from mined and processed uranium to make steam and generate electricity.

One of the main differences between nuclear reaction and chemical reaction is related to how the reaction takes place in the atom. While nuclear reaction takes place in the atom’s nucleus, the electrons in the atom are responsible for Chemical reactions.

Nuclear reaction can be termed as either fission or fusion. Chemical reactions, on the other hand cannot be termed so. In a chemical reaction, a substance is changed to one or more other substances because of the action of the electrons. But in a nuclear reaction, a new element is formed because of the action of the proton or neutron.

Difference Between fission and fusion

The foundation of nuclear energy is harnessing the power of atoms. Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. They are opposing processes, and therefore very different.

Disadvantages of Nuclear Energy

  1. Disadvantages. Like fossil fuels, nuclear fuels are non-renewableenergy resources. And if there is an accident, large amounts of radioactive material could be released into the environment. In addition,nuclear waste remains radioactive and is hazardous to health for thousands of years.
