The paper will review progress to date in this work with illustrative examples of argumentation networks. An outline of future developments and challenges will also be provided, for example considering how confidence in arguments can be assessed, the weakest links in argumentation chains can be identified, arguments can be developed interactively at a level appropriate to all users, etc. Two companion papers demonstrate how these can be applied to critical areas of a repository programme, performance assessment and "geosynthesis". The link to the safety case forms a basis for decision making in the inevitable cases where conflicts between programme requirements arise. The long-term evolution of the safety case also forms a pathway for focusing the future challenges described in the final paper in this set.
