The following figure provides a high level summary of some key milestones, and the broad nature of the research to be undertaken in the different phases to support these milestones, and the decision to close the repository. [...] The safety case for the deep geological repository builds on the concept of placement of the used fuel in a stable host rock, supplemented by other passive durable barriers, and by appropriate facilities and procedures for handling the waste in the near-term. [...] It also includes the decommissioning and closure of the repository, including removal of any remaining equipment, sealing of tunnels and shafts, and the installation and operation of postclosure monitoring systems. [...] The nature of the technical program will evolve over the life cycle of the repository, but there is always a strong technical base to support the safety case for the DGR. [...] However, the direction of the core technical research will be based on the specific design of the repository.
