Nuclear energy

The video discusses the dangers and benefits of nuclear power. It explains how nuclear power stations use uranium to generate large amounts of energy through nuclear reactions. The process involves splitting uranium atoms to produce heat, which is used to create steam that drives turbines and generates electricity. While nuclear power does not emit carbon dioxide, it produces radioactive waste that remains hazardous for thousands of years. The video also highlights the importance of safely managing nuclear waste and the ongoing debate about the safety of nuclear energy, referencing the Fukushima disaster.

• High levels of carbon dioxide

• Dangerous radioactive waste leakage

• Excessive noise pollution

• Lack of electricity

What is the primary fuel used in nuclear power stations?

• Coal

• Uranium

• Natural gas

• Hydrogen

How is the energy from a nuclear reaction primarily used in power stations?

• To power vehicles

• To cool down reactors

• To boil water and create steam

• To heat homes directly

What type of waste do nuclear power stations produce that remains hazardous for thousands of years?

• Metal waste

• Plastic waste

• Radioactive waste

• Organic waste

What is a major concern about nuclear energy despite its low carbon emissions?

• Limited availability of water
