WebThe BWR containments usually consist of the following parts: Drywell. A drywell houses the reactor coolant system. Suppression pool or wetwell. A wetwell is a suppression chamber, which stores a large body of water, and therefore it is commonly called the suppression pool. Containment envelope. WebJan 3, 2024 · What does the condenser do in a BWR? A large heat exchanger designed to cool exhaust steam from a turbine below the boiling point so that it can be returned to the heat source as water. In a pressurized-water reactor, the water is returned to the steam generator. In a boiling-water reactor, it returns to the reactor core.
