Le projet SINAPS@: vers une évaluation intégrée du risque sismique pour la sûreté nucléaire

Abstract : ABSTRACT. The seismic margins assessment of the nuclear plants is a priority for the whole nuclear community, further enhanced since the Tohoku Japan earthquake in 2011. In this framework a 5 years research project called SINAPS@ (Earthquake and 9ème Colloque National AFPS 2015 – IFSTTAR 2 Nuclear Plants: Ensuring and Sustaining Safety) is currently ongoing in France. A reliable estimate of seismic margins is possible only if all uncertainties, epistemic and aleatory, are effectively identified, quantified and integrated in the seismic risk analysis. SINAPS@ brings together a multidisciplinary community of researchers and engineers from the academic and nuclear worlds. SINAPS@ aims at exploring the uncertainties associated to databases, physical processes and methods used at each stage of seismic hazard, site effects, soil and structure interaction, structural and nuclear components vulnerability assessments, in a safety approach: The main objective is ultimately to identify the sources of potential seismic margins resulting from assumptions or when selecting the seismic design level or the design strategy. The whole project is built around an " integrating " work package enabling to test state-of-the-art practices and to challenge new methodologies for seismic risk assessment. The present paper illustrates the crucial links and interactions between all actors of the project to reach the objectives.
