What is Boiling Water Reactor?
A Boiling Water Reactor BWR is a type of light water nuclear reactor used for electricity generation. It heats water directly in the reactor core, producing steam that drives a turbine to generate power. This process means the reactor vessel acts as both the heat source and the steam generator. The steam then cools and condenses back into water, which is pumped back into the core, completing a direct cycle. Its design is simpler than pressurized water reactors because it doesn't require a separate steam generator. BWRs are a fundamental technology in nuclear power production, contributing significantly to global energy supply.
