Boiling Water Reactor
Boiling water reactors (BWRs) have only two loops. Water passes through the reactor core where it boils, creating steam. From the steam generator, a steam line is directed to a turbine that turns a generator used to produce electricity. The steam passes through a condenser where it is turned into water and returned to the reactor core, repeating the process. A secondary coolant loop rejects excess heat energy to the atmosphere.
