Bergmann, C A

Sources of cobalt input in two typical Westinghouse-designed three- and four-loop plants are identified. Quantification of the sources was based on a detailed analysis of the construction materials. The best available information was used to establish the corrosion and wear release rates. This analysis concludes that approximately 70% of the cobalt input arises from corrosion release of Inconel steam generator tubing. Corrosion and wear of high-cobalt alloys account for about 25%. Recommendations are made concerning cobalt reduction options based on a cost-benefit analysis.
