Understand the role of uranium, a radioactive and extremely 'energetic' element, in nuclear energy generation and other industries
Uranium is one of the most fascinating and controversial chemical elements on the periodic table. Represented by the symbol “U”, this heavy metal plays a central role in both nuclear power generation and other industrial applications, scientific and military, according to the video on the Detailed Engineering channel. But what makes uranium so special and, at the same time, dangerous?
What is Uranium and where is it found
Uranium is a chemical element naturally radioactive, found in large quantities in the Earth's crust. Contrary to what many think, it is not rare; in fact, it is one of the most abundant elements on the planet. However, uranium is not found in its pure form, but rather combined in minerals such as uraninite and carnotite.
The largest uranium reserves are concentrated in countries such as Kazakhstan, Canada, Australia, Russia, South Africa and the United States. These countries are the main producers of uranium in the world, extracting it from different types of mineral deposits, such as igneous rocks, sand deposits and sedimentary rocks.
- Brazil may dominate the global uranium market but its HUGE nuclear potential is blocked by an outdated regulatory framework and slow political decisions. Understand:
- 100 reactors in 10 years: China's PLAN to become the world's largest nuclear exporter and lead the global sector
- Brazil moves forward with the US, Russia and China to revolutionize the nuclear sector with new reactors and modernization of Angra
- Angra 1: First Brazilian nuclear power plant guarantees operation until 2044 with an investment of R$ 3,2 billion from Eletronuclear!
Uses of Uranium in power generation and beyond
The main use of uranium is to generate energy and fuel in nuclear reactors, where the fission of uranium-235 generates heat. This heat is converted into electricity, providing energy to millions of people around the world. Nuclear energy is considered one of the most efficient and clean sources of electricity, but its use is also marked by safety concerns and radioactive waste.
In addition to generating energy, uranium has applications in the production of nuclear weapons, where it is enriched to create explosives of enormous destructive power. The arms race of the 20th century and Events such as the Chernobyl accident highlight the dangerous side of inappropriate use of this material.
In medicine, uranium also plays a crucial role. Radioactive isotopes derived from uranium are used in diagnostics and treatments, such as cancer therapy, where radiation helps destroy cancer cells. Other applications include the production of ceramics and glass, fluorescent pigments, and even spacecraft propulsion.
Safety and regulation
Due to its potential risk, Uranium handling is highly regulated. Mining companies and industries that use uranium must follow strict standards to ensure the safety of workers and nearby communities. The use of personal protective equipment, adequate ventilation and constant monitoring of radiation exposure are some of the measures adopted to minimize the dangers associated with radioactivity.
