What is re ac tor?

A reactor is a device that harnesses energy from a nuclear reaction. It is often used in the generation of electricity in power plants. The most commonly used type of reactor is a pressurized water reactor (PWR), which uses uranium rods to create heat through a fission reaction. This heat is used to create steam, which powers turbines to generate electricity. Reactors are highly complex machines that require precise operation and maintenance to operate safely. Any incidents or malfunctions can have severe consequences, such as the Chernobyl disaster in 1986. Despite their potential risks, reactors remain an important source of energy in many countries, providing reliable and low-carbon power.
