摘要

Since the mid-1990s, degradation has been identified in feeder piping at CANDU stations, such as excessive local pipe wall thinning and cracking. The local wall thinning is thought to be attributed to the phenomenon known as Flow Accelerated Corrosion (FAC). Although the cause of cracking is still under investigation, Intergranular Stress Corrosion Cracking (IGSCC) or hydrogen assisted creep cracking are proposed as candidates for the cracking mechanisms. This paper describes the experience of Canadian CANDU industry in the degradation of feeder piping and how it has been managed. The paper also briefly discusses Canadian regulatory actions taken to ensure a safe operation of degraded feeder piping and requirements.
