Abstract
Effect of water flow rate on fatigue crack growth behavior in high temperature water simulating BWR environments was examined by using a flow rate change test method. Materials used in this work were two types of low alloy pressure vessel steels A533B cl 1; one was medium sulfur material (S=0.014 wt%) and the other low sulfur material (S=0.004 wt%). Corrosion potentials during the tests were successfully measured in the relevant conditions.As a result, the fatigue crack growth rate in high temperature water was more accelerated with decreasing flow rate, and this trend was more striking for the medium sulfur material compared to the low sulfur material. Change of corrosion potential during the tests showed a good correlation with the change of water flow rate.
