An Intiative by Sri Chaitanya

For the same mass of substances involved, a fusion reaction releases much more energy than a fission reaction.

A fusion reaction can be much more easily controlled than a fission reaction.

A fusion reaction produces almost no radioactive waste.

The fuel required for fusion is readily available in abundance from sea-water.

Detailed Solution

For the same mass of substances involved, a fusion reaction releases much more energy than a fission.
The initiation mechanism is complex for fusion reactor and also huge amount of energy is required to initiate the fusion reaction. Also, the energy released in the fusion reaction is much greater than the fission reaction for a given mass of the fuel. Release of high energy results in high temperature. Since no container can stand such a high temperature, it is relatively difficult to control nuclear fusion than nuclear fission. Thus, the fission reactors are easily controllable than the fusion reactors.
Fusion reaction produces almost no radioactive waste, and the fuel required for fusion is readily available in abundance in seawater.
