There is increasing and widespread recognition that nuclear energy will feature in the future global energy mix and make its contribution to sustainable development. The growth of nuclear energy and its role in the global energy transition will be influenced by a number of factors. In this report, the future of nuclear is described through the lens of the Council’s World Energy Scenarios archetype framework – Modern Jazz, Unfinished Symphony and Hard Rock – in three plausible, alternative pathways for the future development of the sector. This report also describes implications for the role of nuclear energy in the global energy transition.
