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.

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 Crystalline Club (CRC) is composed of technical experts with experience in evaluating or reviewing the understanding of crystalline rock as host rocks for deep geologic disposal projects. CRC mem...

The Clay Club promotes the exchange of information, shared approaches and methods to develop and document an understanding of clay media as a host rock for a repository.

The main objective of the Salt Club is to make the current knowledge base on rock salt more readily available to member countries, particularly those countries with adequate rock salt deposits to hos...
