World Nuclear Association has published reports on nuclear fuel supply and demand at roughly twoyearly intervals since its foundation in 1975. The 20th edition of the Nuclear Fuel Report was released in September 2021 and includes scenarios covering a range of possibilities for nuclear power to 2040. Forecasts of the years beyond 2040 are beyond the scope of this report and would require a rather different approach to capture the larger range of uncertainty; however, the key issues examined here are likely to have continued relevance during that longer period.
This Expanded Summary covers the key findings of 20th edition, and explains the methodology and the assumption underlying the report’s three scenarios for future nuclear fuel demand and supply. Nuclear power currently contributes approximately 10% of the world’s electricity production. It is expected to play an increasingly important role in future electricity and energy supply for several reasons, including:
Despite these advantages, nuclear energy faces several competitive challenges from other electricity generation sources, especially in deregulated markets as they are currently designed, along with continuing regulatory and political hurdles. Furthermore, electricity demand growth has slowed down, especially in the countries where nuclear power is well-established. At the same time, the nuclear sector remains strong in many developing countries, and it is in these countries that the majority of nuclear capacity growth is expected. China and India alone account for over half the projected new reactors.
[As suggested in the above summary by the WNA, the future impact of the SMRs has been underappreciated, even by the nuclear industry. See: Campbell, et al, (2020), and Lehr and Harris (2022).]
