What is Nuclear Energy? The Science of Nuclear Power | IAEA
Nov 15, 2022 · 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 today to produce electricity is through nuclear fission, while technology to ...

Global Overview of Radioactive Waste and Spent Fuel …
Jan 21, 2022 · There is significant progress in the safe and effective management of radioactive waste and spent nuclear fuel, an IAEA report has found.
What is Uranium? | IAEA
Aug 16, 2023 · Uranium is a naturally occurring radioactive element, which has the atomic number of 92 and corresponds to the chemical symbol U in the periodic table. It belongs to a special group of elements called “actinides” — elements that were discovered relatively late in history. Like all other actinides, uranium is “radioactive” – it decays over time and releases energy in the process ...
What is Nuclear Fusion? - International Atomic Energy Agency
Aug 3, 2023 · Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
What are Small Modular Reactors (SMRs)? - International Atomic …
Sep 13, 2023 · Small modular reactors (SMRs) are advanced nuclear reactors that have a power capacity of up to 300 MW (e) per unit, which is about one-third of the generating capacity of traditional nuclear power reactors. SMRs, which can produce a large amount of low-carbon electricity, are: Small – physically a fraction of the size of a conventional nuclear power reactor. Modular – making it possible ...

Thorium’s Long-Term Potential in Nuclear Energy: New IAEA Analysis
Mar 13, 2023 · Thorium boasts several advantages over the conventional nuclear fuel, uranium-235. Thorium can generate more fissile material (uranium-233) than it consumes while fuelling a water-cooled or molten-salt reactor. According to estimates, the Earth's upper crust contains an average of 10.5 parts per million (ppm) of thorium, compared with about 3 ppm of uranium. “Because of its abundance and its ...
What are Isotopes? - International Atomic Energy Agency
Aug 19, 2022 · An isotopic signature is the set of ratios between the amount of the various isotopes of an element in a sample. Isotopic signatures are commonly known as fingerprints, because they are similar to human fingerprints and are used to track and trace. They are found in water, land, plants and animals. By tracing these fingerprints, scientists can evaluate: the migration of species on land and in ...
