nuclear reactor explanation in 1000 words
Answers
Answer:
The nuclear reactor is an essential system in a nuclear power plant. They include nuclear drain reactions to generate heat using a method called fission. The heat which is generated can be used to make steam for spinning a turbineThe main function of the nuclear reactor is to control nuclear fission. The nuclear reactor working principle is nuclear fission and it is one kind of method used for splitting the atoms to generate electricity. Nuclear reactors use uranium that will process into tiny ceramic pellets & stacked jointly into fuel rods. A fuel assembly can be formed by a bunch of above 200 fuel rods. Usually, a reactor core can be fabricated through these assemblies based on the level of power.
Answer:
nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. As of early 2019, the IAEA reports there are 454 nuclear power reactors and 226 nuclear research reactors in operation around the world.[1][2][3]
