Uranium

German chemist Martin Heinrich Klaproth discovered uranium in mineral bituminous uranium (mainly a mixture of uranium oxide) in 1789. Clapprose and other scientific communities believe that the substance he extracted from the bituminous uranium mine is pure uranium. It is actually uranium dioxide (UO 2). After noticing the strange reaction between "pure" uranium and uranium tetrachloride (UCl 4), radioactivity was first discovered when the French physicist Antoine Henri Becquerel found it from the uranium sample in 1896 It was.

First let's talk about Uranium One. This is the agreement reached in 2010, which allows Russian nuclear authority Rosatom to acquire a 51% stake in Canada's mining company Uranium One. Uranium One has the ability to mining in Wyoming Province, which accounts for 20% of Uranium's capacity in the U.S. The agreement must be approved by the US Foreign Investment Committee. According to FactCheck.org, "The Foreign Investment Committee will represent representatives of the two offices of Ministry of Finance, Ministry of Defense, Homeland Security, Business Energy Minister, Minister of Justice, White House (US Department of Commerce) It consists of nine members including "The deal was approved.

To understand uranium, it is very important to understand the radioactivity. Uranium is inherently radioactive: its nuclei are unstable, so the elements are constantly in a collapsed state, seeking a more stable arrangement. Indeed, uranium is a factor that makes radiation possible. In 1897, French physicist Henri Becquerel left some uranium salts on the photoplate as part of a study on how light affects these salts. To my surprise, the plate was mist-like, indicating that there was some release from the uranium salt. Bequerel received the Nobel Prize in Mary and Pierre Curie in 1903.

As it is naturally radioactive, uranium, usually in the form of uranium dioxide (UO 2), is most commonly used in the nuclear power industry to generate electricity. Naturally occurring uranium consists of three isotopes, uranium 234, uranium 235, and uranium 238. Although all three isotopes are radioactive, the only fissile material that can be used for nuclear power is uranium 235. When a fissile material strikes a neutron, its nucleus can release energy by breaking it into smaller pieces. If several fragments are other neutrons, they will collide with other atoms and split them. Fissile material such as uranium 235 is a substance that produces enough free neutrons to maintain nuclear chain reaction.
