Question

What do you mean by nuclear fission?explain.Advantages as well as disadvantages of nuclear fission.

Answer 1

nuclear fission is either a radioactive decay process in which the nucleous of an atom splits into smaller parts.The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.



Advantages:

• Nuclear energy is a clean energy source in terms of carbon emissions released.
• Nuclear energy is a reliable source of power because the nuclear reactors used today have a pretty long life (they work for decades).
• Nuclear energy is a very powerful source of power which is also efficient (nuclear power has the highest energy density known by man).
• A nuclear power plant generates huge amount of clean electricity in a pretty small space.

Disadvantages:

• Nuclear power produces nuclear waste that is very hazardous for the environment and for any living being.
• Nuclear power is not a renewable energy source because uranium, plutonium and thorium are finite resources.
• Disposing nuclear waste is a very expensive activity that requires both high expenses and heavy military guard for the objective.
• Nuclear power has already produced several radioactive disasters that affected both human life and the environment.
