Reversibility and Retrievability (R&R) for the Deep Disposal of High-Level Radioactive Waste and Spent Fuel. Intermediate Findings and Discussion Documents of the NEA R&R Project. August 2010.


This draft report deals with the concepts of reversibility and retrievability for the deep disposal of high-level radioactive waste and spent fuel. It documents the results of an initiative that was started by the NEA in 2007-2008 with the goal of providing a neutral overview of relevant issues and viewpoints in OECD countries. Some of the discussion will also be applicable to related situations such as that of planning a repository for low- and intermediate-level wastes. The point of view and intended audience for this report is that of someone planning or designing a final repository for high-level wastes or spent nuclear fuel, not that of someone contemplating retrieval.
