英文摘要Reliable predictions of the stress corrosion cracking (SCC) behaviour of 690 weld joints in service for several decades in primary water reactor (PWR) have become increasingly important. Now there is still a huge gap between engineering demands and what current experimentation can reach out to, and a semi-phenomenological predictive tool is proposed to fill this gap. The key idea here is to calibrate the parameters of a partial differential equation model presumably to work during the whole SCC life span against experimentally obtainable information, and then to make predictions over SCC indices that are not experimentally reachable. Experimental studies are also conducted to measure the crack growth rates under ten working conditions of interest. Upon calibration, the proposed predictive tool can deliver, within a few seconds on a normal laptop, the evolution profile of crack throughout the whole SCC process. As a rather aggressive case in PWR, the SCC crack initiation time of a 20% cold worked 690 weld joint bearing a 0.5 mm-deep scratch is predicted to be similar to 40 years under an applied load of 200 MPa. With the calibrated model, an explicit formula to predict the PWSCC crack incubation time of 690 weld joints is finally given against various aqueous, mechanical, metallurgical and geometric factors.
