A nuclear reactor generates power by harnessing the energy released from nuclear fission. Here's a step-by-step breakdown of how it works: 1. Nuclear Fission Inside the reactor core, uranium-235 (or sometimes plutonium-239) undergoes fission, meaning its atoms split apart when struck by neutrons. This process releases a huge amount of heat energy along with more neutrons, which continue the chain reaction. 2. Heat Generation The heat produced from fission is absorbed by a coolant, usually water, which flows through the reactor core. In some reactors, other coolants like liquid metal or gas are used. 3. Steam Production In most reactors, the heated coolant is used to boil water, turning it into high-pressure steam. 4. Turbine Rotation The steam is directed onto turbine blades, making them spin. This converts the heat energy into mechanical energy. 5. Electricity Generation The spinning turbine is connected to a generator, which produces electricity by converting mechanical energy into electrical energy through electromagnetic induction. 6. Cooling & Recycling After passing through the turbine, the steam is cooled down in a condenser, often using water from a nearby lake, river, or cooling tower. The cooled water is then recycled back into the system to be heated again. Types of Nuclear Reactors Pressurized Water Reactor (PWR) - Keeps water under high pressure to prevent boiling in the reactor core. Boiling Water Reactor (BWR) - Boils water directly in the reactor to produce steam. Fast Breeder Reactor (FBR) - Uses fast neutrons and creates more fuel than it consumes.
