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 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.
What are Isotopes? - IAEA
Aug 19, 2022 · The IAEA helps countries build capacity to use isotopic techniques and to produce radioisotopes and radiopharmaceuticals.

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 need a higher concentration of this ...

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.

The 1986 Chornobyl nuclear power plant accident | IAEA
Jun 13, 2013 · On 26 April 1986, the Number Four reactor at the Chornobyl Nuclear Power Plant in what then was the Soviet Union during improper testing at low-power, resulted in loss of control that led to an explosion and fire that demolished the reactor building and released large amounts of radiation into the atmosphere. As safety measures were ignored, the uranium fuel in the reactor
