Question

Mentions any four differences between nuclear fission and nuclear fusions.

Answer 1

Nuclear Energy

1. The energy released by either splitting up of a heavy unstable nucleus or by fusion of two or more light nuclei is called nuclear energy.

The differences between Nuclear fission and fusion:

Nuclear fission	Nuclear fusion
A heavy unstable nucleus breaks into two or more lighter nuclei.	Two or more lighter nuclei combine to form a heavy nucleus.
The fuel used in nuclear fission is Uranium-235 and Plutonium-239.	In nuclear fusion, the fuel is Tritium and Deuterium.
The availability of fuel is limited and expensive	The availability of fuel is unlimited and cheap.
The possibility of the chain reaction is only in the nuclear fission reaction.	There is no possibility of the chain reaction
The amount of energy released in nuclear fission is large.	The amount of energy released in the nuclear fusion reaction is much higher than that released in fission.
