What is a nuclear reactor?

nuclear reactor is a piece of scientific equipment that is designed to generate controlled chain reactions of fission elements such as uranium. Nuclear reactors can be used for a number of purposes, including electricity production, nuclear fuel production and scientific research. Nuclear reactors of various designs can be found in many regions of the world, from scientific laboratories in the United States to the French landscape, the French relying on nuclear energy for approximately 75% of their power in 2009. In a controlled fission reaction, this energy can be used for different activities and will be forced to create a chain reaction that encourages the rest of the fission element to also disintegrate. An uncontrolled reaction creates a nuclearbomb.

inside the nuclear reactor are fuel rods made of fission element inserted into a moderator, a material that slows neutrons to supportSlipped. The nuclear reactor operator can control the reaction using control rods, rods made of materials that absorb neutrons. When the rods are lowered into the reactor core with fuel, they absorb neutrons, slow down or stop the cleavage process, and when they are raised, allow fuel rods to absorb neutrons and undergo cleavage. Fuel rods are spent regularly and need to be replaced by fresh fuel, while the spectic fuel must be carefully destroyed to prevent contamination.

The

nuclear reactor also requires coolant to transfer heat from the reactor core. Heat, a by -product of cleavage, can actually be the aim of reactor operators because it can be used for Generate Elevrick by generating steam that will push the turbines. When a nuclear reactor is used for scientific research, the heat may be an undesirable by -product, although some reactors are designed for both research and electric production for maximum efficiency.

to KONThe trolls and the limitation of the nuclear reactor are involved in a huge number of systems. The inherent risk of creating a controlled reaction is that the reaction can cascade out of control. This concern is solved with numerous failures and safety technologies that are designed to function safely. Nuclear reactors have relatively few large accidents and those that occur in older reactors with insufficient support infrastructure.
