What is fission?

Back

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. It is the process used in nuclear power plants.

Front

What is fusion?

Back

Fusion is a nuclear reaction where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. It powers the sun but is not yet used in power plants.

Front

Why is nuclear fusion not yet used in power plants?

Back

Nuclear fusion is not yet used in power plants because it is not technologically feasible with current technology.

Front

What is uranium?

Back

Uranium is a heavy metal that is commonly used as fuel in nuclear reactors due to its ability to undergo fission.

Front

What is the most common nuclear fuel used today?

Back

The most common nuclear fuel used today is uranium.

Front

What is a renewable resource?

Back

A renewable resource is a natural resource that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen to produce heat and light, commonly used in engines and power generation.

Front

What is the difference between renewable and nonrenewable resources?

Back

Renewable resources can be replenished naturally and are sustainable, while nonrenewable resources are finite and cannot be replaced once used.
