Nuclear power
Nuclear Power
Nuclear power (pronunciation: /ˈnjuːklɪər ˈpaʊər/) is the use of nuclear reactions to produce electricity.
Etymology
The term "nuclear" comes from the Latin nucleus, meaning "core". The term "power" comes from the Latin potere, meaning "to be able". Thus, nuclear power refers to the ability to harness the energy from the core of an atom.
Definition
Nuclear power is a type of power generation that uses the heat produced by nuclear reactions to generate steam, which then drives a turbine to produce electricity. The most common type of nuclear reaction used for power generation is nuclear fission, in which the nucleus of a heavy atom, such as uranium or plutonium, is split into two or more smaller nuclei, releasing a large amount of energy in the process.
