Cozine/Shutterstock The biennial nuclear fuel market report from the World Nuclear Association (WNA) forecasts global nuclear power capacity nearly doubling from 398 gigawatts electric as of June to 746 GW by 2040. This increase in capacity is expected to create a supply-demand gap, in part due to longer lead times for mine development, but also thanks to a technical change in how the WNA accounts for available secondary supplies. The big reduction in secondary supply forecasts prompted bitter disagreement between producers looking to lock in higher long-term price commitments and the utilities on the other side of the negotiating table. Save for later Print Download Share LinkedIn Twitter The influential biennial nuclear fuel market report from the World Nuclear Association has, since 2019, predicted increases in nuclear generating capacity, but the 2025 World Nuclear Fuel Report anticipates a near doubling of nuclear power capacity by 2040, with uranium supply in particular struggling to keep pace. This proved a contentious finding, with nuclear fuel buyers, sellers and traders sharply at odds over the mid-2030s supply gap forecasted in this year’s report.
