Q & A

What is nuclear energy?

Nuclear energy is energy obtained from the nucleus of atoms. It involves reactions that release energy from atoms, either by splitting them (fission) or combining them (fusion). The nuclear energy we use today relies on fission.

How does nuclear fission work?

In nuclear fission, atoms of uranium or plutonium are split, releasing a large amount of heat. This heat is used to generate steam, which drives turbines to produce electricity.

What is the difference between nuclear fission and fusion?

Nuclear fission involves splitting atoms, while nuclear fusion involves combining atoms. Fission is currently used in nuclear energy production, while fusion is a potential future energy source that does not produce radioactive waste.

What materials are used in nuclear fission?

Uranium and plutonium are the main materials used in nuclear fission. These elements are abundant and are used in power plants to generate energy.

What are some benefits of nuclear energy?

Nuclear energy offers several benefits, including producing large amounts of energy with minimal land use, not generating greenhouse gases, and having a small volume of waste. It is highly efficient compared to other energy sources.

How much energy can 1 kg of uranium produce?

1 kg of uranium can produce energy equivalent to 1.5 million kg of coal, highlighting the immense energy output of nuclear energy.

What are the disadvantages of nuclear energy?

The major disadvantages of nuclear energy include the high initial cost of building nuclear power plants and the hazardous radioactive waste produced, which can cause mutations and harm to living beings.
