Reactor types (pressurized water reactor, boiling water reactor)

Reactor types like Pressurized Water Reactors (PWR) and Boiling Water Reactors (BWR) are methods used in nuclear power plants to generate electricity. In a PWR, water is kept under high pressure so it doesn't boil; it heats the water, which stays liquid and transfers heat to produce steam in a secondary loop that drives turbines. In a BWR, water boils directly inside the reactor vessel, producing steam that directly drives turbines. Both use nuclear reactions to generate heat but differ in how they manage and use water to produce electricity efficiently and safely.
