An Assessment for Emergency Preparedness Plan in Hanul Nuclear Power Plant

Abstract

The purpose of emergency preparedness aims to protect the accident and mitigate the radiation damage of public by setting emergency preparedness plan. In order to perform successfully the emergency preparedness plan, it should be optimized through a quantitative analysis. There are so many variables to analyze it quantitatively. It is mission to classify a realistic and suitable variables among these variables. The realistic variables is converted to the decision node in decision tree which is helpful to decide what evacuation or sheltering is effective to mitigate public damage. Base on it, it's idealistic method to analyze offsite consequences for each end points in the decision tree. In this study, we selected the reference plant which already has the emergency preparedness plan. Among the plan, we implemented offsite consequence analysis for a specific plan by using MACCS 2 code. In this study, target group is people who gathered in place 1 have sheltered and evacuated along the pathway. the offsite consequences analysis result of the group are 1.17·10-9 (early fatality), 1.77·10-7 (late fatality). Various cases need to be quantified for make an optimized decision. In the future, we will perform the verification and modification of decision node. After The assessment of emergency preparedness plan for Hanul nuclear power plant unit 5, 6 might be contribute to establish the optimized decision making of emergency prepared plan
