Nuclear Fission and Fusion

Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is a nuclear reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is the primary process that powers the sun?

Back

The primary process that powers the sun is nuclear fusion.

Front

What are the conditions necessary for nuclear fusion to occur?

Back

Nuclear fusion requires extremely high temperatures and pressures to overcome the electrostatic repulsion between positively charged nuclei.

Front

What is the difference between nuclear fission and fusion?

Back

Nuclear fission involves the splitting of a heavy nucleus, while nuclear fusion involves the combining of light nuclei.

Front

What is a common fuel used in nuclear fission reactors?

Back

Uranium-235 is a common fuel used in nuclear fission reactors.

Front

What is the energy output of nuclear fusion compared to nuclear fission?

Back

Nuclear fusion releases significantly more energy per reaction than nuclear fission.

Front

What is a chain reaction in the context of nuclear fission?

Back

A chain reaction in nuclear fission occurs when the products of one fission event cause additional fission events, leading to a self-sustaining series of reactions.

Front

What is the role of neutrons in nuclear fission?

Back

Neutrons are crucial in nuclear fission as they can initiate the fission process by colliding with the nucleus of a fissile atom.

Front

What is the main advantage of nuclear fusion over nuclear fission?

Back

The main advantage of nuclear fusion is that it produces less radioactive waste and has a virtually limitless fuel supply.
