What is the difference between nuclear fusion and fission?

What is the difference between nuclear fusion and fission?

Nuclear fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing energy. Fission, on the other hand, involves splitting a heavy nucleus into lighter nuclei, also releasing energy.

Which process is more powerful?

Fusion is generally more powerful than fission. For example, fusion reactions in stars release significantly more energy than fission reactions.

What are the practical applications of each?

Fission is used in nuclear power plants and atomic bombs, while fusion is still largely experimental but has potential for clean energy.

Are there any safety concerns with fission?

Yes, fission carries risks such as nuclear accidents, radioactive waste, and proliferation of nuclear weapons.

What about the safety of fusion?

Fusion is considered safer as it doesn't produce long-lived radioactive waste and carries a lower risk of catastrophic failure.
