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.

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.

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 …

Aug 3, 2023 · Nuclear fusion and plasma physics research are carried out in more than 50 countries, and recently researchers have finally achieved scientific energy gain in a fusion experiment for the first time.Experts have come up with different designs and magnet-based machines in which fusion takes place, like stellarators and tokamaks, but also approaches that …

Jan 22, 2025 · The IAEA is the world's centre for cooperation in the nuclear field, promoting the safe, secure and peaceful use of nuclear technology. It works in a wide range of areas including energy generation, health, food and agriculture and environmental protection.

Jan 25, 2023 · Health: thanks to radiation, we can benefit from medical procedures, such as many cancer treatments, and diagnostic imaging methods.; Energy: radiation allows us to produce electricity via, for example, solar energy and nuclear energy.; Environment and climate change: radiation can be used to treat wastewater or to create new plant varieties that are resistant to …

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.

Jan 12, 2024 · The IAEA’s Incident and Emergency Centre (IEC) received information from the International Seismic Safety Centre at approximately 08:15 Vienna Time concerning an earthquake with a magnitude of 9.0 near the east coast of Honshu, Japan’s main island.. This was followed by an accident at the Fukushima Daiichi Nuclear Power Station, which was ultimately …

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 …

LiveChart is an interactive chart that presents the nuclear structure and decay properties of all known nuclides through a user-friendly graphical interface. Most of the accessible data are taken from the Evaluated Nuclear Structure Data File (ENSDF), which is …
