Question

Quizplus · Accepted Answer

In a boiling-water reactor (BWR), the water used as coolant and moderator is allowed to boil inside the reactor itself, turning directly into steam which then drives the turbine. In contrast, a pressurized-water reactor (PWR) keeps water under pressure to prevent it from boiling, and uses a separate steam generator where the heat is transferred to a secondary loop of water to produce steam.
