Based on the risk-informed methodology recommended by IAEA-TECDOC-1652, considering both the frequency of the entire spectrum of accident scenarios and the dose consequence for each scenario, this paper analyzes and calculates the EPZ size...

... to develop a more comprehensive, holistic, and technology-inclusive DID strategy is explored in this study. A risk-informed (RI) method is adopted to improve the DID strategy by combining the traditional DID concept with a risk-informed approach. Considering the gradual development of risk assessment methods...
