Seismic Initiating Event (IE) analysis is one of the most important tasks that control the level of effort and quality of the whole Seismic Probabilistic Safety Assessment (SPRA). The typical problems are related to the following aspects: how the internal PRA model and its complexity can be used and how to control the number of PRA components for which fragility evaluation should be performed and finally to obtain a manageable number of significant cut-sets for seismic risk quantification. The answers to these questions are highly dependent on the possibility to improve the interface between the internal events analysis and the external events analysis at the design stage. (authors)
