The last Café Scientifique of this year will be held on Thursday the 14th of December from 5pm at the French Institute of Finland (Yrjönkatu 36, 3rd floor). The aim of those Cafés Scientifiques is to regularly gather the French-speaking and Francophile scientific community of Finland in a casual atmosphere, and to initiate new encounters between participants and to exchange on our joint projects.


5.00: Welcoming words and introduction of the speakers
5.10: “Beliefs in the Middle Age” by Nicolas Faucher (University of Helsinki, Centre of Excellence of the Academy of Finland)
5.40: “Research in nuclear safety” by Mélany Gouëllo (VTT – Technical Research Centre of Finland)
6.10-7.00: Reception

Nicolas Faucher

Nicolas Faucher, researcher at the Centre of Excellence of reason and religious recognition of the Academy of Finland, is a doctor of philosophy from the École pratique des hautes études and the Università degli Studi di Bari. Specialized in medieval philosophy, he focuses more particularly on the philosophical foundations of religious beliefs, the subject of his doctoral thesis rewarded by a Chancellerie prize. In the framework of a long-term associative commitment, he also tackles the problem of radicalization in contemporary societies.

According to popular belief, catholic religious belief is, in the Middle Age, an authoritarian injunction and not a free choice. However, if they indeed defend the condemnation and severe punishment of heresy, medieval catholic theologians attach considerable importance to the freedom of belief, condition under which the act of faith is authentically virtuous. His intervention will be dedicated to the study of this paradox.

Mélany Gouëllo

In 2012, she obtained a doctorate in chemistry from the University of Grenoble, which she carried out at the Radioprotection and Nuclear Safety Institute (IRSN) in Cadarache, France. The study focused on the understanding of iodine behavior in the primary circuit of a nuclear reactor during a serious accident. She then joined VTT Oy., the Technical Research Centre of Finland. Since then, her research focuses on the experimental study of the transportation and the chemistry of fission products in the situation of an accident.

She will explain why the research conducted in VTT (but also on an international level) is focusing specifically on the behavior of iodine and ruthenium. She will describe the “methodology” used to study the behavior of fission products with the aim to reduce uncertainties regarding the assessment of the source term. She will then introduce the transportation of fission products from the reactor core to the containment chamber, the mitigation system and the phenomenons studied at VTT.
