Study on Containment Overpressure Fragility Curve and Ultimate Load for CPR1000

Abstract

Based on the results of international researches and design feature, the CPR1000 containment model was built with FEA method and the ultimate load was analysed. Besides, the uncertainties of main design parameters was identified and quantified and then the containment over-pressure fragility curves for CPR1000 were obtained with PSA method.
