Nuclear Energy

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting an atom's nucleus into smaller parts, releasing a large amount of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is a nuclear meltdown?

Back

A nuclear meltdown is a severe nuclear reactor accident that results in the core overheating and melting.

Front

What is radioactive waste?

Back

Radioactive waste is material that contains radioactive substances and poses a risk to health and the environment.

Front

What is a nuclear isotope?

Back

A nuclear isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

True or False: Nuclear fission is currently used as a sustainable energy source.

Back

False. While nuclear fission is used for energy, it is not considered sustainable due to radioactive waste.

Front

What are the advantages of nuclear energy?

Back

Advantages include low greenhouse gas emissions, high energy density, and reliability as a power source.

Front

What are the disadvantages of nuclear energy?

Back

Disadvantages include the risk of accidents, radioactive waste disposal, and high initial costs.

Front

What is the role of a nuclear reactor?

Back

A nuclear reactor is a device used to initiate and control a sustained nuclear chain reaction for energy production.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction occurs when the products of one fission event cause further fission events, sustaining the reaction.
