External Events Safety Section

The External Events Safety Section supports Member States as they select sites for nuclear installations, assess external hazards and evaluate safety design against external events. It covers a wide range of external events, including earthquakes, floods, landslides and events induced by human activities.

The section’s work supports Member States in the selection and evaluation of sites for nuclear power plants, research reactors and fuel cycle facilities. It also offers resources to help States ensure that site characteristics are sufficiently considered when the installation is designed.

In cooperation with Member States, the section develops IAEA safety standards and documents for site investigation and site evaluation to provide guidance on the protection of safety functions against external hazards such as earthquakes, floods, geotechnical effects, high-winds and aircraft crashes. The section also offers assistance in enhancing management systems, promoting periodic safety reviews and assessing the risks of external events to support continuous improvement of existing nuclear installation safety. In addition, it provides a forum for the sharing of experiences.  

The Site and External Events Design (SEED) peer review service assists Member States in the application of safety standards related to site and external events design. The service entails an in-depth peer review that results in comments and recommendations. SEED expert missions and workshops also assist Member States – on request – in strengthening their capacity in site selection, site evaluation and external event design.

The section also manages extra-budgetary projects funded with Member States’ voluntary contributions with the aim of developing enhanced methods and tools to support assessments of sites and nuclear installation safety against external hazards. The EESS portal, restricted for registered users, allows stakeholders to collaborate and exchange information on such projects.

The Section provides support to Member States in building and sustaining capacity in nuclear safety. Learn more about the Section's work in this area.
