[en] Whereas Europe is one of the most nuclear regions of the world, political orientations regarding civil nuclear in Western Europe are very different and even sometimes opposite, and, in the contrary, the position of Eastern Europe is rather homogeneous with a rather good acceptance of nuclear energy by the political world and the civil population. This article proposes an overview of these different situations, first by addressing the United Kingdom and Finland who are developing their nuclear power production, by describing the situation of nine European countries who decided to definitely stop nuclear (with a focus on Italy), by presenting the French posture as a half-measure, by presenting the case of three Western European countries which are questioning their will to phase out nuclear (Belgium, Netherlands and Sweden, with a focus on this last country), by presenting the Visegrad Group as the most nuclear one in Eastern Europe (focus on Czech Republic, Romania). It briefly addresses the case of Baltic states which recently phased out nuclear but still have a common nuclear project, and the case of Balkan states (a low nuclear region but in favour of nuclear, with a focus on Slovenia). Then, starting in 1957, a brief history of the European is proposed. The role of the European nuclear industry in the world is then discussed. Sheets are then proposed with indications and brief comments on resources and on the composition of the electric power mix, on economy, infrastructures and organisation, and on the nuclear policy for several European countries (Germany, Austria, Belgium, Bulgaria, Croatia, Spain, Estonia, Finland, France, Hungary, Italy, Netherlands, Poland, Czech Republic, Romania, United Kingdom, Slovakia, Slovenia, Sweden, Switzerland). Brief presentations about energy resources and posture with respect to nuclear energy of other European countries are finally provided.
