What is Nuclear Energy? The Science of Nuclear Power | IAEA
2022年11月15日 · The Science of Nuclear Power. 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 – or fusion – when nuclei fuse together. The nuclear energy harnessed around the world ...

What are Small Modular Reactors (SMRs)? - International Atomic …
2023年9月13日 · Small – physically a fraction of the size of a conventional nuclear power reactor. Modular – making it possible for systems and components to be factory-assembled and transported as a unit to a location for installation. Reactors – harnessing nuclear fission to generate heat to produce energy. Learn more about nuclear fission and energy.
What is Nuclear Fusion? - International Atomic Energy Agency
03 Aug 2023. Matteo Barbarino, IAEA Department of Nuclear Sciences and Applications. Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy. Fusion reactions take place in a state of matter called plasma — a hot, charged gas made of positive ions and free ...

What are Radiopharmaceuticals? - IAEA
2024年2月2日 · Radiopharmaceuticals are drugs that contain, among other ingredients, radioactive forms of chemical elements called radioisotopes. Depending on the type of radiation that those radioisotopes produce, they can be used to diagnose or treat several medical conditions. Their applications range from imaging of many different organs, such as brain ...
What is Uranium? | IAEA - International Atomic Energy Agency
2023年8月16日 · There are three natural isotopes of uranium — uranium-234 (U-234), uranium-235 (U-235) and uranium-238 (U-238). U-238 is the most common one, accounting for around 99 per cent of natural uranium found on earth. Most nuclear reactors use fuels containing U-235, however, natural uranium typically contains only 0.72 per cent of U-235 and, most reactors need a higher concentration of this ...
