Degradation in performance of pressurized water reactor steam generators after several years in operation has been reported in recent years. The major concern is the tube cracking caused by tube and support plate corrosion. Recent studies indicate that the level of oxygen concentration in the feedwater plays an important role in starting steam generator corrosion. The functions of a deaerator in the steam cycle is to reduce the concentration of dissolved gases, particularly oxygen, to a low level. An economic analysis has been performed to select the cycle for the pressurized water reactor plant with the installation of a deaerator to the turbine regenerative cycle.
