FAQ
Frequently Asked Questions
Yes, for practical purposes they are synonyms. 'Nuclear energy' is the more contemporary and frequently used term.
Because the energy comes from reactions within the atom's nucleus (fission or fusion), which changes the atom's structure.
It is often classified as a low-carbon energy source, but not strictly renewable, as it relies on finite fuels like uranium. It is sometimes called a 'sustainable' energy source.
Its primary civilian use is to generate electricity in nuclear power plants. It is also used in medicine (e.g., radiation therapy) and scientific research.
