Fusion & Fission

Front

What is fusion?

Back

Fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. It is the reaction that powers stars, including our sun.

Front

What is fission?

Back

Fission is the process of splitting a heavy atomic nucleus into two lighter nuclei, along with the release of energy. This process is used in nuclear power plants and atomic bombs.

Front

Do all stars produce energy through fusion?

Back

Yes, all stars produce energy through the process of nuclear fusion.

Front

What is an example of an uncontrolled fission reaction?

Back

An example of an uncontrolled fission reaction is an atomic bomb.

Front

Why is fusion considered a potential energy source for the future?

Back

Fusion is considered a potential energy source because it produces a large amount of energy with minimal radioactive waste and has abundant fuel sources like hydrogen.

Front

How do nuclear power plants generate electricity?

Back

Nuclear power plants generate electricity through the process of fission, where the nucleus of an atom is split to release energy, which is then used to heat water and produce steam that drives turbines.

Front

What is one disadvantage of nuclear energy?

Back

One disadvantage of nuclear energy is that it leaves behind radioactive waste, which poses environmental and safety challenges.

Front

What fuels are commonly used in nuclear fission?

Back

Common fuels used in nuclear fission include uranium-235 and plutonium-239.

Front

What is the role of neutrons in fission reactions?

Back

Neutrons play a crucial role in fission reactions by colliding with heavy nuclei to initiate the fission process.

Front

What is the difference between controlled and uncontrolled fission?

Back

Controlled fission occurs in nuclear reactors where the reaction is regulated to produce energy safely, while uncontrolled fission occurs in atomic bombs, leading to an explosive release of energy.
