Based on recent theoretical progresses, the NARSIS project aims at making significant scientific step forward towards addressing the update of some elements required for the safety assessment. These improvements mainly concern:

  • Natural hazards characterization, in particular by considering concomitant external events, either simultaneous-yet-independent hazards or cascading events, and the correlation in intra-event intensity parameters.

  • Vulnerability of the elements to complex aggressions, with the integration of new approaches such as vector-based fragility surfaces and reduced models

  • Better treatment of uncertainties through adoption of probabilistic framework for vulnerability curves and non-probabilistic approach to constraining the “expert judgments”.
