General Conclusions

Major accidents in nuclear reactors are rare, but the consequences are catastrophic. There are many causes of nuclear accidents, but their main cause is often human error due to misinterpretation of the warning signals of an accident. Accident prevention requires an exhaustive inventory of all possible nuclear accidents, an analysis of the consequences of each of them and the search for solutions to avoid, or at least minimize, the impacts of these various accidents. Accident modeling and simulation research has developed since the Chernobyl accident, and even more since the Fukushima accident. The consequences of nuclear accidents affect many aspects of society and therefore present challenges for multiple actors at various spatial and temporal scales. Gralla et al. call for transdisciplinary research to improve the study of nuclear accidents and increase the potential for communication, collaboration and co‐production of knowledge in this field.
