Some aspects of a statistical methodology for the evaluation of the radiological impact over Italy of severe nuclear accidents at European NPPs is presented. As an example of application of the methodology, some numerical results obtained using codes specifically developed by IRSN are given. The results are presented in the form of threshold trespassing probability maps at two different scales. Time-integrated 137Cs air concentrations and 137Cs surface depositions are used as indicators. The methodology and related codes will be applied in the next years for support activities in the field of Emergency Preparedness and Response and for nuclear risk assessment and emergency management strategies.

Abstract
Some aspects of a statistical methodology for the evaluation of the radiological impact over Italy of severe nuclear accidents at European NPPs is presented. As an example of application of the methodology, some numerical results obtained using codes specifically developed by IRSN are given. The results are presented in the form of threshold trespassing probability maps at two different scales. Time-integrated 137Cs air concentrations and 137Cs surface depositions are used as indicators. The methodology and related codes will be applied in the next years for support activities in the field of Emergency Preparedness and Response and for nuclear risk assessment and emergency management strategies.| File | Dimensione | Formato | |
