ocr: the vessel. After steam in formed in the reactor vessel, it flows to a serles of steam separators where it is separated from the coolant. The steam then flows through steam dryers where additional drying is done, and then it proceeds to turn a turnogenerator. The control rods and reactor vessel func- tion in the same way as in the pressurized water reactor. satety systems are designed to prevent meitdown in both types of light water reactors. The safety systems in a pres- surized water reactor include the residual heat removal sys- tem, the emergency core cooling systems, and the contalnment b ...
