What is Uranium? | IAEA 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
What is Nuclear Energy? The Science of Nuclear Power What is nuclear fission? 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
Sufficient Uranium Resources Exist, However Investments Needed to . . . Sufficient uranium resources exist to support both the continued use of nuclear power and its significant growth through 2050 and beyond However, timely investments in new exploration, mining operations and processing techniques will be essential to ensure that uranium becomes available to the market when needed
Uranium Exploration Planning, Management and Practice The objective of this Technical Document is to provide clear guidance including best practices and recommendations for the planning, management and implementation of uranium exploration projects It provides a systematic approach to the development and implementation of uranium exploration programmes
Uranium production for nuclear reactors | IAEA Uranium is the primary fuel for nuclear reactors and must be managed properly, in a safe and sustainable manner Recent annual production of natural uranium world-wide has been between 55,000 and 65,000 tons of uranium metal, similar to the fuel demand Additionally, thorium is also being investigated as a potential alternate source of nuclear
Production d’uranium pour les réacteurs nucléaires | AIEA L’uranium est le principal combustible utilisé dans les réacteurs nucléaires Il doit être géré correctement, de façon sûre et durable Ces derniers temps, la production annuelle mondiale d’uranium naturel était comprise entre 55 000 et 65 000 tonnes d’uranium métal, soit l’équivalent de la demande en combustible nucléaire Le thorium, qui pourrait constituer une source
Depleted Uranium - International Atomic Energy Agency The International Atomic Energy Agency (IAEA) defines uranium as a Low Specific Activity material In its natural state, it consists of three isotopes (U-234, U-235 and U-238) Other isotopes that cannot be found in natural uranium are U-232, U-233, U-236 and U-237 The table below shows the fraction by weight of the three isotopes in any quantity of natural uranium, their half lives, and
World Distribution of Uranium Deposits, Third Edition This third edition of the World Distribution of Uranium Deposits presents new information, such as additional deposits, a broader range of deposit sizes, a revised deposit classification system and improved geological visualization information (see the map explanation, key, and legend for detailed information)
Depleted uranium: sources, exposure and health effects Information is given on sources of depleted uranium exposure, the likely routes of acute and chronic intake, the potential health risks from both the radiological and chemical toxicity standpoints and future research needs Several ways of uptake of compounds with widely different solubility characteristics are also considered
Uranium Extraction Technology | IAEA The purpose of this publication is to update and expand the first edition, which was published in 1983, and to report on later advances in uranium ore processing It includes background information about the principles of the unit operations used in uranium ore processing and summarizes the current
