What is Nuclear Energy? The Science of Nuclear Power | IAEA
Nov 15, 2022 · Nuclear fission is a reaction where the nucleus of an atom splits into two or more smaller nuclei, while releasing energy. For instance, when hit by a neutron, the nucleus of an atom of uranium-235 splits into two smaller nuclei, for example a barium nucleus and a krypton nucleus and two or three neutrons.
Global Overview of Radioactive Waste and Spent Fuel …
Jan 21, 2022 · As a growing number of countries use nuclear technology to generate electricity and radioactive material for many other purposes, there is significant progress in the safe and effective management of radioactive waste and spent nuclear fuel arising from these activities, including the development of deep geological repositories (DGRs), an IAEA report has found.
What is Uranium? | IAEA - International Atomic Energy Agency
Aug 16, 2023 · 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 …
