GENERAL KNOWLEDGE

Detailed explanation-1: -Inside nuclear power plants, nuclear reactors and their equipment contain and control the chain reactions, most commonly fuelled by uranium-235, to produce heat through fission. The heat warms the reactor’s cooling agent, typically water, to produce steam.

Detailed explanation-2: -Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.

Detailed explanation-3: -All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation.

Detailed explanation-4: -While fission is used in nuclear power reactors since it can be controlled, fusion is not yet utilized to produce power. Some scientists believe there are opportunities to do so. Fusion offers an appealing opportunity, since fusion creates less radioactive material than fission and has a nearly unlimited fuel supply.

Detailed explanation-5: -Therefore, nuclear fission is defined as: The process in nuclear physics in which the nucleus of an atom splits into two daughter nuclei. When Uranium-235 atom is bombarded with a neutron, it splits into two lighter nuclei Barium and Krypton.
