Method for Mitigating Nuclear Power Plants Accident Damage in Nuclear Power Plant Areas through a Non-structural Approach: Focusing on Land Use Planning

Abstract

Nuclear power plant accidents cause enormous damage. Safety probabilities for nuclear power plant accident prevention are being studied to enhance safety. However, research has been lacking due to damage reduction, not prevention of accidents. This study proposes land use planning, through a non-structured approach, as a way to mitigate damage. For this purpose, risk tothe areas surrounding the nuclear power plant was analyzed. In this study, human casualties were set as the chief damage. We looked at population changes in areas surrounding nuclear power plants and used a Difference-in-differences analysis for this purpose. From the analysis results, land use planning scenarios were established to mitigate the damage from nuclear plant accidents, and asimulation was conducted to determine the reduction effect. The model was conducted on the basis of System Dynamics, and the scenario was constructed and simulated using a land use planning approach. From the simulation results, a policy proposal was also made regarding the land use planning method to mitigate damage to nuclear power plants.
