#### Nuclear Fission :-

When the nucleus of an atom splits into lighter nuclei through a nuclear reaction the process is termed as nuclear fission. This decay can be natural spontaneous splitting by radioactive decay, or can actually be simulated in a lab by achieving necessary conditions (bombarding with neutrinos). The resulting fragments tend to have a combined mass which is less than the original. The missing mass is what is converted into nuclear energy in the above reaction. Therefore, nuclear fission is defined as:
The process in nuclear physics in which the nucleus of an atom splits into two daughter nuclei.

#### Nuclear Energy :-

All matter is made of tiny atoms. All atoms have a nucleus at their core, where most of their mass is concentrated. In specific circumstances, it is possible for this nucleus to undergo certain changes. Nuclear fusion (as the name suggests) is a process of combining small atoms, resulting in heavier atoms with more energy. Nuclear fission is splitting of the nucleus of a heavier atom into a smaller one. Both these processes release a tremendous amount of energy. And how does that happen?

Remember Einstein’s famous equation E = mc?

where,

E is energy
m is mass
c is the speed of light in vacuum

Although the mass in consideration is really small, the speed of light is a large number (299792458 m/s). When this potential was realized it led to the field of harnessing nuclear energy (literally the energy in the nucleus).

The good thing about nuclear energy is that it has the potential to generate a lot of energy/power without any emission of pollutants. The only disadvantage is the disposal of nuclear waste has to be done extremely carefully.

#### The Chernobyl Accident :-

Nuclear power plants cannot be thoroughly discussed without mentioning nuclear accidents. There is no tale which is more vivid or sobering than that of Chernobyl. The Chernobyl power plant, located about 80 km north of Kiev, Ukraine in the former Soviet Union, was an RBMK-1000 type reactor.
