Disposal of radioactive waste in geological formations is widely recognised by the global scientific community as the most viable solution for the long-term isolation of high-level waste and spent nuclear fuel from the human environment. While the principles underpinning geological repositories are mature and internationally endorsed, engaging with key stakeholders and addressing important societal components remains challenging in many countries. Additionally, the rise of interest in nuclear energy and expanding inventories brings new hurdles to consider in geological repository development.
This publication provides a synthesis of the Seventh International Conference on Geological Repositories (ICGR-7) hosted in Busan, Korea, in May 2024. The conference brought together high-level decision-makers, regulatory authorities, radioactive waste management organisations, academia, public stakeholders, students and young professionals, to review current progress and perspectives on geological repository development. Advances in geological disposal were highlighted, including improved public engagement and stakeholder confidence, use of underground research laboratories to support international co-operation and R&D, role of the safety case in supporting DGR siting, and concrete shifts in several national programmes towards the licensing phase of DGR programmes. Certain challenges remain, such as improving human capacity, adapting to an evolving technological landscape, and the potential notion of multinational infrastructures for managing radioactive waste.
