Abstract :
A fusion DEMO reactor, like other advanced nuclear energy systems, must satisfy a range of goals including a high level of public and worker safety, low environmental impact, high availability, a closed fuel cycle, and the potential to be economically competitive. It is well known that the experience of the ITER project will facilitate DEMO programs in developing a safety approach and safety design, performing safety analyses under the scrutiny of a nuclear regulator, ensuring reactor availability, managing radioactive wastes, and conducting economic assessments. However, there are still huge scientific and technological gaps between the current ITER and any DEMO reactors. In this work, the international efforts for fusion safety research and development towards DEMO will be summarized following lessons learned from ITER. The main scientific and technological challenges, particularly considering the differences between ITER and DEMO, will be presented with the views not only from the fusion energy development but the development of other advanced nuclear energy systems in particular Generation-IV fission reactor. Moreover, the potential future role of International Energy Agency (IEA) implementing agreement (IA) on a co-operative program on Environmental, Safety and Economic aspects of Fusion Power (ESEFP) will also be addressed in leading the DEMO safety R&D.
