Nuclear power

Nuclear power is the use of nuclear reactions to generate electricity, most commonly through the fission (splitting) of heavy atoms such as uranium.

How it works

In a reactor, controlled fission releases heat, which turns water into steam that drives turbines. It produces large amounts of energy from small amounts of fuel.

Benefits and concerns

Nuclear power emits little carbon dioxide, but it raises concerns about radioactive waste and accidents such as Chernobyl and Fukushima.

Frequently asked questions

How does nuclear power work?

By splitting atoms to release heat that generates electricity.

Is nuclear power clean?

It produces very low carbon emissions but creates radioactive waste.
