Risk Assessment Method for Accidental Releases from Nuclear Power Plants inEurope

摘要

This study aims at a quantitative risk assessment of the probabilistic excessdeath risk related to possible accidental releases to the atmosphere from European nuclear power reactors. The risk estimates must be seen as a first attempt to achieving an integrated risk assessment, since many uncertainties are involved in the calculating the source-to-risk chain. The risk assessment method presented in this report combines accident probabilities for all European reactors using air dispersion and deposition calculations with an exposure assessment model. Risk assessment methods can be valuable tools in supporting policy-makers in the decision-making process, providing a common ground for balancing costs and benefits of countermeasures. The method applied in this study could, with adjustments, also be used in the assessment of risks due to other environmental pollutants.
