The NEA hosted an online expert roundtable discussion on 24 June 2021 on safety case projects of three different types of disposal facilities in member countries.

The Expert Group on Operational Safety (EGOS) aims to identify, evaluate and help define international best practice in operating geological repositories for radioactive waste safely.

On the occasion of this anniversary, the NEA has published a commemorative brochure that reflects on 20 years of IGSC work and traces the evolution of the concept of the safety case overall.

The IGSC has identified various tools that can be used to structure and thus better manage and transfer the ever-increasing amounts of information and knowledge across a project lifetime.

The design and implementation activities of the Integration Group for the Safety Case (IGSC) focus on how to achieve safety in practice.
