摘要

Since 1997, sections of nine ASME SA 106 Grade B carbon steel primary coolant system piping at the Point Lepreau Generating Station (PLGS) have been replaced because of intergranular cracking. This cracking at PLGS is unique among the world's CANDU~R reactors and has potential to have a significant negative impact on the safe and reliable operation of the Station. Although the mechanism(s) of cracking initiated from both inside and outside surfaces has not been confirmed, several primary causal or proximate factors have been identified that form the basis for cost-effective risk management strategies. New Brunswick Power Nuclear (NBPN) uses a combination of three strategies to manage the observed cracking, depending on the probability of cracking at that location in the piping system, the potential for risk reduction in applying the strategy, and the time in the reactor life cycle. The strategies are: Inspection and Repair, Demonstration of Low Risk, and Prevention of Cracking.rnThis paper describes the methods used to select appropriate management activities based on economic analysis and risk reduction.
