ICONE19-43921 COMPARISON OF PRO-LOCA 2009 AND WINPRAISE 2007 FOR ESTIMATING RUPTURE PROBABILITY OF DISSIMILAR METAL WELD SUSCEPTIBLE TO PWSCC

This paper presents a preliminary study using probabilistic fracture mechanics codes (PRO-LOCA 2009 and WinPRAISE 2007) to estimate the rupture probability of Dissimilar Metal Weld (DMW) in CANDU^[!R] small diameter feeder piping subject to potential Primary Water Stress Corrosion Cracking (PWSCC). In spite of the significant differences in the deterministic fracture mechanics models and algorithms used for speeding up Monte Carlo calculations,...
