Since the early 1980s, Westinghouse has been recognized as the industry leader with regard to engineering analysis of operating steam generator degradation. We've gained experience and developed tools to accurately assess degradation and optimize operational efficiency when degradation mechanisms exist. Westinghouse has also led the industry in developing steam generator tube alternate repair criteria (ARC) for keeping degraded tubes in service. We continue to make advancements in flaw modeling and integrity projection analysis (operational assessment) methods, consistent with the current industry guidelines and in development of improved eddy current (EC) analysis techniques to support operational assessments.
