• Nuclear energy is a clean, safe way to make electricity. It does not burn any fuel like coal so there are no pollutants released into the air.

• The principles of nuclear power were found in the 20th century by German scientists.

Nuclear Power - How it worksHow it works• In order to use this energy, it has to be released

from the atom. There are two ways to free the energy inside the atom.

1. Fusion• Fusion is a way of combining the atoms to make a

new atom.2. Fission• Fission is a way of splitting an atom into two smaller

atoms. The two smaller atoms don't need as much energy to hold them together as the larger atom, so the extra energy is released as heat and radiation.
