Containment is the last barrier to achieve radioactive products contained,the pressure of which may exceed the design value under the severe accident condition.Study of containment over-pressure integrity and failure probability,is an important part for the severe accident management and Level-2 PSA research.In this paper,the experiment and analysis in SANDIA of USA is described,the containment over-pressure fragility probability AP1000,EPR and Generation II+ NPPs are analyzed and studied,relevant methodology and result can be reference for severe accident management strategy and Level-2 PSA research.
