Nuclear reactor: What is Nuclear Reactor

What is Nuclear Reactor ? The nuclear reactor (or atomic reactor ) is a furnace in which energy is produced by the nuclear fission process. Learn what a nuclear reactor is, how it works, and what are its main components and types. A nuclear reactor is a system that uses nuclear fission to generate heat and electricity using uranium fuel and water as coolant and moderator. Nuclear reactors are devices that control nuclear fission to release energy, primarily for electricity generation. By splitting uranium or plutonium atoms, reactors produce heat, which generates steam to drive turbines. Known for high energy output and low greenhouse gas emissions, nuclear reactors play a key role in modern energy systems. A nuclear reactor is a device used to sustain a controlled fission nuclear chain reaction. They are used for commercial electricity, marine propulsion, weapons production and research. Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating neutron absorbers and moderators in the core. Fuel efficiency is exceptionally high; low-enriched uranium is ...
