The Tohoku earthquake and associated tsunami in March 2011 caused a severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant, where level 7 (International Atomic Energy Agency (IAEA) – INES scale) meltdown at three reactors occurred. The underestimation of the seismic and tsunami hazards has been recognized and the seismic margins assessment of the nuclear facilities remains a priority for the whole nuclear community.
Objectives and Content of the SINAPS@ International Training Course
The objectives of the 2018 SINAPS@ Training session are:
- to get a large international audience, composed by young and experienced scientists, engineers and professionals involved in the seismic risk analysis, for conventional or specific buildings (such as dams, chemical or nuclear sites…),
- to propose a strong training team, merging all the scientific specialties interacting when assessing the seismic risk for a sensitive building or equipment, from the field geology, to the seismology, the geotechnical and civil engineering, and the probabilistic approach experts,
- to expose the state of the art in each topic of the full risk analysis topic,
- to present and discuss the current classical “engineering approaches” in line with the regulatory references,
- to underline the current scientific debates and/or challenges,
- to present and illustrate on case-studies, experimental seismic campaigns or through simulations, at the forefront of innovation, as recently developed, experienced or validated in the frame of SINAPS@ project,
- to motivate scientific debates but also practical issues between trainers and participants.
With its organization in plenary sessions and specialized modules, the training aims to provide to all participants a common high level of knowledge of current practices in seismic risk analysis, and an in-depth presentation of most recent findings and developments coming from ongoing research.
