Stuctural Seismic Fragility Analysis of the Zion Containment
In a collaborative program between the United States Nuclear Regulatory Commission and the Nuclear Power Engineering Corporation (NUPEC) of Japan, the seismic behavior of a Prestressed Concrete Containment Vessel (PCCV) model was investigated. A 1:10 scale PCCV model was constructed by NUPEC and subjected to seismic simulation tests. Dynamic 3D finite element analyses were performed before and after the seismic tests. Utilizing the same material models developed for the PCCV analysis, a detailed finite element model was developed for the Zion Nuclear Power plant containment structure and seismic analyses were performed. Material models that were validated by previous scaled model seismic tests and analyses were used. The Zion model was then subjected to 30 different earthquake time-history accelerations. In addition, Latin Hypercube Sampling, was used to vary all the material and modeling parameters of the input in order to get a realistic distribution for this limited set of runs. Fragilities were generated based on the limiting concrete shear strains.
