概要
Control Rod Cluster Guide Tubes (GTs) in PWR nuclear plant have the possibility to be worn due to fluid induced vibration of Control Rod Clusters. The maintenance rul es for GTs had been established after the discussion with experts, and GTs in Japanese PWR plants have been already maintained in accordance with these maintenance ru les. In these rules, the inspection period is decided based on the wear data and the wear progressing prediction with the assumption of constant wear speed. This pape r describes the validity of the concepts about maintenance period based on the wear progressing prediction, by using the consecutive inspection data of actual plants.
