Modeling of a Major Accident in Five Nuclear Power Plants From 365 Meteorological Situations in Western Europe and Analysis of the Potential Impacts on Populations, Soils and Affected Countries (original) (raw)

The present study discusses the probability of a major accident in a nuclear power plant and, by simulation of such an accident, it evaluates the harm to people. It aims at characterizing the health effects of ionizing radiation, and it assesses the number of people impacted by a radioactive cloud, and by the deposition of radioactive material on the ground. It further evaluates the number of people in need of a resettlement. It also analyses the size of the area lost for agriculture due to radio-contamination. More specifically, the Western European nuclear power plants (NPPs) under scrutiny are Beznau, Gosgen, Leibstadt and Muhleberg in Switzerland and Bugey in France. The study models a major nuclear accident using meteorological files, one for each day during the year 2017 with help of the trajectory and dispersion model Hysplit. The source terms of the simulated accidents are specific to each of the five NPPs. They represent an amount situated between the Fukushima and Chernoby...
