What is Nuclear Energy? The Science of Nuclear Power
网页2022年11月15日 · Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – …
Nuclear power - Wikipedia
网页Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
Nuclear Energy - Our World in Data
网页Nuclear energy – alongside hydropower – is one of our oldest low-carbon energy technologies. Nuclear power generation has existed since the 1960s but saw massive growth globally in the 1970s, 1980s, and 1990s. The interactive chart shows how global nuclear generation has changed over the past half-century.
