Answers
Difference Between Nuclear Fission and Nuclear Fusion
Basis Nuclear Fission Nuclear Fusion
Definition Fission would be defined as the division of single atom into multiple atoms of small size. Fusion would be defined as the joining of two or more small atoms to form a large atom.
The necessity of Energy Requires less energy to divide atoms to two or more ones. Huge amount of energy required to combine small atoms to form a large atom.
The release of Energy The amount of energy released in fission is much lower than the energy released in fusion. The release of energy in fusion is way higher than that of the fission reaction.
Production/Usage of energy Used to produce energy in nuclear power plants. The technology is used for experiments in power plants.
Natural Reactions Never occurs in nature in normal cases. Happens in natural forces like stars and sun.
Ideal Conditions There is a necessity to have a critical mass of the substance and neutrons with high speed. Requires high density and high-temperature atmosphere.
Reaction Outcome The fission reaction produces highly radioactive substances. Very few radioactive chemicals come out of this reaction.
Fuel Used Uranium is one of the primary fuels in nuclear power plants. Hydrogen isotopes are used as fuel in experimental plants.
