Reactor core

A reactor core is the central part of a nuclear power plant where nuclear reactions occur. It contains fuel rods filled with uranium or other radioactive materials, which undergo controlled fission — a process where atoms split, releasing heat. This heat is used to produce steam that drives turbines, generating electricity. The core is carefully engineered with control rods and cooling systems to manage the reaction safely, prevent overheating, and ensure consistent power output. Essentially, it’s the heart of the plant where the energy from splitting atoms is harnessed to produce electricity efficiently and safely.
