Risk-Informed Support of Nuclear Power Plant Risk Zoning

This paper analyses the background, objectives and current status of the information basis leading to the definition of risk and emergency zones around nuclear power plants (NPPs). Although dependable plant-specific Probabilistic Safety Assessment (PSA) of Level 2 and/or Level 3 could provide sufficiently detailed input to define the geographical dimension of a NPP's risk and emergency zones, the analysis of the status in some European and other countries shows that other, basically "deterministic" approaches are used in practice. Based on currently used decision criteria in defining NPP emergency zones in some European countries, issues such as definition of emergency zones, information to the public in the event of radiological emergency and emergency protection measures are discussed. Recommendations are given to overcome this gap in more comprehensive use of available risk information.
