This publication has been developed to help Member States ensure that appropriate sites for a nuclear power plant are identified, assessed and licensed, in a well planned and efficient manner, taking into account all relevant factors and lessons learned from recent events. It is applicable to countries with existing nuclear facilities as well as those introducing nuclear power in their energy mix. This IAEA Nuclear Energy Series publication provides guidance on the complex organizational, engineering, socioeconomic and environmental issues of siting. It complements the IAEA Safety Guides related to site selection and integrates existing IAEA documentation on the subject into a more compact and user friendly guidebook.
