Geological repositories for the disposal of radioactive waste are designed to contain and isolate the emplaced waste by means of engineered and natural barriers. While the operations of geological repositories are somewhat similar to the operations of nuclear facilities (e.g. nuclear power plants), geological repositories that are being located deep below ground (hundreds of meters) require specific design and operational provisions to ensure their safety for the entirety of their lifetimes. Both the NEA and the IAEA have long recognised the importance of operational safety. Projects and work initiatives have been carried out with different work scopes and objectives to address various operational safety issues. For instance, the NEA IGSC created the Expert Group on Operational Safety (EGOS) in 2013 to develop the best operating practices and the optimal design provisions of geological repositories. The expert group has since issued several reports ranging from fire risk management in underground facilities to co-activity planning, ventilation system design, etc. Whereas the IAEA had launched the GEOSAF Project in 2008, it has since been used as a forum to exchange ideas and experience on the development and review of safety cases for geological disposal facilities among their member states. The IAEA GEOSAF Project, now in its second phase, focuses on developing a methodology to define an overarching safety case supporting the demonstration of safety of geological disposal, integrating both the operational and post-closure periods.
The workshop focuses on three key topics: 1) technical design aspects, e.g. fire risk management, on-site transportation and emplacement; 2) repository regulatory framework and requirements; and 3) radiological protection issues in DGR, each one consisting of small group discussions guided by specific questions.
The working language of the workshop will be English.
