Th e decision depends on the state of the nuclear fuel after it has been used in the reactor. It can then be reprocessed to be reused as fuel, or it can be disposed of.

Nuclear fuel can last from 3 to 5 years in the nuclear reactor. Through this process, large amounts of electricity are produced.ДЄfter the fuel has been used, it is removed from the reactor and stored. From this heat, high temperature, pressurized steam is generated, which is used to spin a turbine. This process is known as вЂњnuclear fissionвЂќ and it generates considerable heat. To convert the fuel into energy, it is pressurized and the uranium atoms split apart, creating large amounts of energy. Once the fuel rods are placed into the core, they are ready to be converted into nuclear energy. In large nuclear reactors, there may be over 18 million pellets and 50 thousand fuel rods used in a reactor! Nuclear Fission These fuel pellets are then placed into fuel rods (also called вЂњfuel assembliesвЂќ) which make up the core of a nuclear reactor. To get the enriched uranium ready for nuclear reactors, it is converted back to a powder, called uranium dioxide (UOв‚‚), which is packed into small fuel pellets.

For integrated companies, they will sell enriched UFв‚† as part of their Fuel Services. This makes it easier to use in nuclear reactors. Enrichment is done to increase the amount of uranium present in the gas (compared to its natural levels). Gas Conversion and EnrichmentДЄfter the вЂњyellow cakeвЂќ is produced, it is then converted into a gas known as uranium hexaflouride (UFв‚†) that is enriched to produce fuel. Furthermore, the sale of uranium is heavily regulated due to its nuclear capabilities and it is monitored by governmental bodies such as the U.S. However, the spot market is not as important to sales, compared to other commodities, since uranium is mostly purchased in major long-term contracts. This concentrate is the powdery yellow substance known as вЂњyellow cakeвЂќ and it is the form sold on the spot market. Once the uranium has finished drying, it leaves the mine as the concentrate of a stable oxide known as triuranium octoxide (Uв‚ѓOв‚€), which is a solid form of uranium. This treatment helps to separate the uranium from its surrounding rock. The techniques are comparable to those used for mining other commodities, such as gold and silver.ДЄfter mining out the ores, they are crushed down and dissolved through an acid treatment. There are various methods used to extract uranium ore, depending on the depth at which the deposit is in the ground. Mining and TreatmentДЄlthough uranium is all around us in very low concentrations, only rich and dense deposits of uranium can be used to mine the ores needed for nuclear energy. As this terminology is often included in financial reporting of uranium companies, it has been included in this overview. Note: There will be some chemical terms used to describe the different refining processes used on uranium.

How does Nuclear Energy work? The Nuclear Fuel CycleДЇor nuclear energy to be produced, the uranium used in this process needs to be refined, affecting its chemical composition. In fact, over 70% of FranceвЂ™s total energy consumption comes solely from nuclear energy. Some countries, such as France, Slovakia, and Ukraine, rely on nuclear energy as their primary source of energy. While the largest uranium producers are Kazakhstan and Canada (with notable production from Australia, Niger, and Namibia), the countries that consume the most nuclear power include the United States, France, and China. Who are the Biggest Producers and Consumers of Uranium? Given that many countries are looking to reduce their overall GHG emissions, there has been an increase in nuclear reactors in development over the last 5 years. Nuclear energy does not emit greenhouse gases (also known as GHG emissions), making it an attractive energy source compared to traditional sources such as coal, crude oil, and natural gas. Uranium is important since it is used as a fuel source for nuclear energy reactors, which contribute to ~15% of global energy consumption. Why is Uranium and Nuclear Energy Important? Uranium must go through a refining process (mining, conversion, and enrichment) to become suitable for nuclear energy generation.Since nuclear energy does not produce GHG emissions, it has gained popularity as an alternative energy source.Uranium is the primary element used in nuclear energy, one of the most important global energy sources.
