How a Nuclear reactor work? একটা পারমাণবিক চুল্লী কিভাবে কাজ করে?

 Nuclear reactors operate on the principle of nuclear fission. Nuclear fission occurs when a neutron bombardment happened with  a larger atom, forcing it to excite and split into two smaller atoms—also known as fission products. Additional neutrons are also released that can initiate a chain reaction. When each atom splits, a tremendous amount of energy is released.The kinetic energy produced during the fission reaction is converted into thermal energy.Fission releases a tremendous amount of energy in the form of heat.Uranium is the fuel most widely used in nuclear reactors at power plants. //

At the center of a nuclear reactor is the core, which contains fuel fabricated from uranium ore. Uranium ore is mined and processed to be eventually formed into ceramic pellets.

Nuclear power reactors use heat  to boil water and produce pressurized steam.

The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger. Those tubes heat a separate water source to create steam. The steam is routed through the reactor steam system to spin large turbines blades that drive magnetic generators to produce electricity. The core water cycles back to the reactor to be reheated and the process is repeated.//

Any nuclear reactor that produces power via the fission of uranium (U-235) or plutonium (Pu-239) by bombardment with neutrons must have at least some key  components: nuclear fuel consisting of fissionable material, The Core,a nuclear moderator, reactor coolant, control rods, The Cooling Tower, and a shield or containment system.//

Fissile materials are materials that can undergo the fission reaction. They are the key component of nuclear weapons or other nuclear explosive devices. Those mostly used in nuclear weapons are highly enriched uranium (U-235 isotope of uranium) and plutonium (Pu-239 isotope of plutonium

The Core: It contains all the fuel and generates the heat required for energy production.

The Coolant: It passes through the core, absorbing the heat and transferring into turbines.

Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel– uranium or plutonium.

The Turbine: Transfers energy into the mechanical form..

⦁ The Cooling Tower: It eliminates the excess heat that is not converted or transferred.

⦁ The Containment: The enveloping structure that separated the nuclear reactor from the surrounding environment.

Nuclear fission is nearly 8,000 times more efficient at producing energy than traditional fossil fuels: oil, gas and coal.
