Write a paragraph explaining how a nuclear reactor works. Be sure to explain the purpose of the control rods.
Uranium as a fuel :Uranium, like all other atomic elements, occurs in several different forms, known as isotopes. The second-most common isotope, U-235 (0.71%), is the one used to generate electricity, because it can easily undergo fission. Because nuclear fission is a very efficient source of energy, nuclear reactors require very little fuel. A single 20-gram uranium fuel pellet can produce the same amount of energy as 400 kilograms of coal, 410 liters of oil, or 350 cubic meters of natural gas.
Nuclear fission - working of reactors :Uranium (both U-235 and U-238) is relatively stable before entering the reactor. However, when a U-235 atom is bombarded with a neutron, it often splitS into several pieces, ejecting two or three extra neutrons. This process releases heat, which can be converted into electricity. These neutrons interact with other nearby U-235 atoms and cause the effect to continue – much the way billiard balls can continue striking other ones after the cue ball has stopped moving. By controlling the concentration of nuclear fuel and slowing or absorbing neutrons, nuclear reactors stabilize this chain reaction at the desired rate.
Significance of control rods :Control rods are made of materials that absorb neutrons, such as boron, silver, indium, cadmium, or hafnium. They are introduced into the reactor to reduce the number of neutrons and thus stop the fission process when required. They are also used to control the level and distribution of power in the reactor.

this is questioned seven from Chapter three, Section six and asked me to explain what a nuclear reactor is and what is the purpose of the control broads. So a nuclear reactor? It is also known as in the comic. Wow. Reckon. Basically, hopes start and controlled a nuclear chain reaction. No make clear reactions. Reactors are basically used, especially to signed facilities, and these reactors basically come using uranium for a nuclear fuel. And this comes from the nuclear fission also helps control nuclear chain reaction. Nuclear fission is stable before enters a reactor, but when it comes in contact with some neutrons, it splits, creating three extra neutrons, which releases heat and that can be converted into electricity. And another part that hopes converse isn't electricity or the control rods. Control rods absorb neutrons to reduce the number other insurance, and this is supposed to help try to stop proficient process
