Plant design characteristics and operating philosophy relative to secondary cycle chemistry control at Ringhals Nuclear Power Station Unit 2 were reviewed. Ringhals 2 experienced moderate steam generator corrosion during the early history of plant operation. Since the corrosion appeared related to the introduction of contaminants into the secondary cycle from intermittent condenser tube leakage, the condensers have been retubed with titanium. Steam generator 3 has been subject to more extensive denting than numbers 1 and 2. This steam generator also appears to have operated at slightly higher chloride concentrations particularly during periods of condenser inleakage. No explanation for the observed differences could be developed.
