Secondary system chemistry and steam generator corrosion observations at the Millstone 2 pressurized water reactor are summarized. Condenser retubing and retrofit of full-flow condensate polishers led to significant improvements in steam generator blowdown chemistry following observations of denting after one year of operation at elevated blowdown chloride levels. Notwithstanding the chemistry improvements, denting has continued but at a much reduced rate. In addition, extensive pitting of the Alloy 600 tubing between the tubesheet and first support plate has been reported recently.
