reactor cooldown

Reactor cooldown is the process of reducing a nuclear reactor's temperature after it has been operating at high power levels. This is achieved by gradually lowering the reactor’s heat output, often by adjusting control systems and increasing coolant flow. The goal is to safely bring the reactor to a lower temperature, ensuring that the fuel and components are not subjected to thermal stress or damage. Cooldown is a controlled process essential for maintenance, safety checks, or emergency shutdowns, helping to prevent overheating and maintaining the integrity of the reactor’s safety systems.
