Although PWR secondary chemistry control has improved markedly, steam generator corrosion attack has continued at many plants emphasizing the need for developing improved chemistry control specifications. An approach to developing such specifications employing correlations of steam generator corrosion with crevice chemistry predictions based on bulk water chemistry, impurity ingress, or hideout return data is outlined. Recommended actions for addressing deficiencies in the available laboratory data base on which such correlations could be developed are proposed.
