Note: Large amounts of energy are released in nuclear fission reactions (around 200 Mev), but the more important issue is that the result of breaking the uranium-235 nucleus is the release of two neutrons, which can break two other nuclei and produce four neutrons. These four neutrons also break four uranium-235 nuclei. Four broken nuclei produce eight neutrons, which are able to break the same number of uranium nuclei, then the nuclear break and the release of neutrons in a chain-like manner rapidly multiply and develop.

Uranium, when refined, is a silvery-white metal with weak radioactive properties, which is a little softer than steel. This thorn hammer metal is a conductor of electricity and slightly paramagnetic. The density of uranium is 65% higher than the density of lead. If the uranium is separated well, it is strongly affected by cold water and oxidizes against the air. Uranium extracted from mines can be chemically transformed into uranium dioxide and other species that can be used in industry.




Types of Uranium in the  Uranium Industry There are three types of Uranium in the industry:

• Alpha (Orthohombic) which is stable up to 667.7 degrees.

• Beta (Tetragonal) which is stable from 667.7 to 774.8 degrees.

• Gamma (Body-centered cubic), which is stable from a temperature of 774.8 degrees to the melting point. (This is the most conductive and malleable form of uranium.)



Its two important isotopes are U235 and U238>, which U235 is the most important for nuclear reactors and weapons. Because this isotope is the only isotope that exists in nature and is split by thermal neutrons in every possible amount. The U238 isotope is also important because it absorbs neutrons to produce a radioactive isotope and decomposes it into the Pu239 plutonium isotope. The synthetic isotope U233 is also fissioned and created by neutron bombardment of Thorium232. Uranium was the first element discovered that could be fissile. For example, with the slow neutron bombardment of the isotope U235, it turns into the short-lived isotope U236 and immediately splits into two smaller nuclei, which releases energy and produces more neutrons. If these neutrons are absorbed by another U235 nucleus, the nuclear ring action occurs again and if there is nothing to absorb the neutrons.



Conclusion : 

In nuclear fission reactions, large amounts of energy are released (around 200 Mev), but the more important issue is that the result of breaking the uranium-235 nucleus is the release of two neutrons, which can break two other nuclei and create four neutrons. These four neutrons also break four uranium-235 nuclei. Four broken nuclei produce eight neutrons, which are able to break the same number of uranium nuclei, then the nuclear break and the release of neutrons in a chain-like manner rapidly multiply and develop.
