A recent report released by the World Nuclear Association has drawn widespread attention in the international energy sector. The report indicates that as countries gradually view nuclear power as a clean and stable strategic energy source during the energy transition, global uranium demand will rise sharply over the next 15 years, increasing from approximately 86,000 tons in 2030 to 150,000 tons in 2040. However, in sharp contrast to the demand, the existing mine capacity is expected to drop by half during this period. The gap between supply and demand is increasingly evident and may become a significant hidden concern hindering the global nuclear energy revival.
The revival of nuclear energy and the crucial position of uranium
The position of nuclear energy in the global energy structure is transforming. Since the outbreak of the Russia-Ukraine conflict, many European countries have re-examined energy security issues. France, the United Kingdom, and Finland have all announced the extension of the operating life of nuclear power units and plan to build new reactors. The United States has explicitly supported the research and development of small modular reactors (SMRS) and advanced nuclear energy technologies in the Inflation Reduction Act. Asian countries such as China, Japan, and South Korea are also actively making investments in nuclear energy. The International Energy Agency (IEA) pointed out in its latest forecast that by 2050, nuclear energy is expected to meet approximately 18% of the global electricity demand.
However, as the sole major source of nuclear fuel, the vulnerability of uranium’s mining, processing, and supply chain directly determines the sustainability of nuclear energy development. Industry insiders are generally concerned that if uranium supply remains tight, the construction and operation of nuclear power plants may slow down due to rising fuel costs, and even affect the nuclear power development plans of some emerging market countries.
Market shocks and price expectations
The price of uranium has shown a significant upward trend since 2022. According to data from market firm UxC, the spot price of uranium has risen by more than 60% over the past two years and is now approaching a high of $90 per pound. Analysts believe that if the development of new uranium mining capacity is hindered in the future, the price may exceed $100 per pound, exerting heavy cost pressure on global nuclear power operators.
Investment bank analysts on Wall Street pointed out that fluctuations in uranium prices not only affect the operating costs of nuclear power plants but may also undermine investor confidence and delay some planned nuclear power projects. Especially in emerging economies such as South America, Africa, and Southeast Asia, project financing often relies on international lending institutions. If the cost of uranium fuel is too high, the feasibility assessment of related projects will be challenged.
In addition, the shortage of uranium supply may also drive market speculation. In recent years, many uranium-themed exchange-traded funds (ETFs) have attracted a large amount of investor capital inflows. Once the imbalance between market supply and demand intensifies, speculative demand may amplify price fluctuations, posing additional risks to the stability of the industry.
Policy background and international cooperation
In the face of this potential crisis, many governments have begun to plan countermeasures. The U.S. Department of Energy (DOE) is advancing the “Strategic Uranium Reserve Program”, planning to purchase a certain scale of domestically produced uranium in case of supply disruptions. The European Commission has called on member states to diversify their uranium supply chains and reduce reliance on a single region. Under the framework of the Belt and Road Initiative, China actively participates in the development of uranium mines in Central Asia, Africa, and other regions to ensure the long-term fuel supply for domestic nuclear power development.
The International Atomic Energy Agency (IAEA) has also recently emphasized that the transparency and cooperative development of uranium resources should be promoted globally to avoid supply chain disruptions caused by geopolitical frictions. The agency called on all countries to expand the scale of nuclear power while investing more funds in uranium exploration and the research and development of alternative fuels, such as thorium-based fuel cycles and fast neutron proliferators.
Expert opinions and industry reactions
Energy policy scholars generally believe that the bottleneck in uranium supply is a major weakness in the global nuclear energy revival. A professor from the Center for Energy Policy at Harvard University told The New York Times in an interview, “Without sufficient uranium mining and supply chain guarantees, the clean energy potential of nuclear energy will be severely limited. This is also a problem that governments and industries around the world must face up to.”
Meanwhile, industry giants are also taking action. Cameco of Canada and Kazatomprom of Kazakhstan have announced increased investment to enhance production capacity. But analysts warn that the development of new mines usually takes a cycle of 7 to 10 years, and it is difficult to ease the supply and demand contradiction in the short term.
Environmental protection organizations, however, have issued different voices, calling on all countries to carefully assess the potential environmental damage caused by uranium mining before the large-scale promotion of nuclear energy. Greenpeace pointed out in a statement that uranium mining may lead to water pollution and land degradation. Without strict supervision, it may not be worth it.
Outlook
Overall, the shortage of uranium supply has become an unavoidable challenge in the global nuclear energy revival process. If countries fail to make breakthroughs in uranium resource development, alternative fuel research and development, and supply chain security within the next decade, the strategic role of nuclear energy in the global clean energy system may be weakened. As the World Nuclear Association has warned, the future of nuclear energy depends not only on technological progress and policy support, but also on whether uranium, a key fuel, can be sustainably supplied.
At the critical juncture of the energy transition, the global energy market is closely monitoring the direction of this supply and demand game. Whether it is energy security or climate governance, the issue of uranium supply will continue to affect the international energy landscape in the next ten to two decades.
