The Safety Case for Deep Geological Disposal of Radioactive Waste: 2013 State of the Art

(2nd International Safety Case Symposium)
7-9 October, 2013
Paris, France

Organised in co-operation with the European Commission and the International Atomic Energy Agency

Home Objective Programme with presentation links

Geological disposal is now well established as the ultimate end-point for managing long-lived radioactive waste in a safe manner which will protect human and the environment passively for the required long time scales (more information is provided in the RWMC 2008 Collective Statement).

The modern concept of the "safety case" was first introduced by the OECD/NEA Expert Group on Integrated Performance Assessment (IPAG) and was developed in the OECD/NEA confidence document of 1999. Since then the concept has been adopted internationally. The revised NEA brochure Post-closure Safety Case for Geological Repositories (2013) reviews and discusses the purpose and general contents of a safety case. Similar concepts are presented in the IAEA Safety Requirements on Geological Disposal of Radioactive Waste WS-R-4 (2006), and in the recent document: Disposal of Radioactive Waste, IAEA Specific Safety Requirements SSR-5 (2011) specifically states that developing a safety case, presenting it for review and using it as input for decision-making is an explicit requirement. The recent EU Directive (2011/70/Euratom) on radioactive waste and spent fuel management also shows consistent perception of a safety case.

In 2007, the NEA, in concert with the IAEA and the EC, organised the first Symposium entitled: Safety Cases for the Deep Disposal of Radioactive Waste: Where Do We Stand?

Since 2007, there have been major developments in a number of national geological disposal programmes and significant experience has been obtained both in preparing and reviewing cases for the operational and long-term safety of proposed and operating repositories. The purpose of the Symposium is to determine and document changes in the state-of-the-art since 2007.
