摘　　要：This paper provides an overview of the degradation in CANDU^a （Canadian Deuterium Uranium） feeders in operating plants observed from the mid 1990s onward. The degradation has been dominated by feeder wall thinning, caused by FAC （flow accelerated corrosion） and feeder cracking. This paper summarizes the industry＇s response to the discovery of these two degradation mechanisms and the methodologies, tools and technologies developed to monitor the degradation and assess the continued fitness for service to manage the plant life. This paper identifies some of the lessons gained from more than a decade of industry effort, and discusses how these lessons are being implemented in the refurbished and new CANDU plants. CANDU^a is a registered trademark of Atomic Energy of Canada Limited.
