Nuclear Fission & Reactor

Nuclear Fission

The nuclear fission reaction refers to a reaction that splits of nucleus into two or more fragments. The every splits releases energy that could use in many different ways.  Fission reaction occurs when a nucleus divided into two or more fragments, releasing neutrons and energy. The uranium isotope, U-235, undergoes fission reaction when it bombarded with a neutrons. The element barium and Krypton are the result of the reaction. In fission on or more of the neutrons causes the fission, that fission releases three more neutrons, each one neutron causes more fission. This continual process of fission reaction called a chain reaction. 

Nuclear Reactor

Once the fission reaction started if continues until the reaction has finished. In this reaction it releases alpha, beta or gamma rays. In our time the fission reaction are used to generate electricity. A power station are built near to a river where large body of water available.  A nuclear power station is divided into many different sector. In one sector fuel road or reactor are immersed into water. Once the reaction starts it produces heat energy that boils the water and the steam than goes through a pipe and hits turbines to spine. As turbines starts to rotate it generates electricity. In the mean time when chain reaction starts its needs to be control otherwise it will burn everything and the radiation will free to move in the atmosphere. To stop the reaction control rods immersed in water. This rods are made of cadmium metal that can easily absorb neutrons. When they inserted into the reactor, they absorb enough of neutrons releases by the fission reaction to prevent further chain reaction.
