United States aims to boost soft power through thorium reactor research

Highlights
  • China's progress in molten salt reactor technology presents competition for the United States.
  • The thorium fuel cycle poses risks associated with nuclear proliferation, necessitating international cooperation.
  • Re-investing in thorium technology could position the United States as a leader in sustainable energy and increase its global influence.
Story

In 2025, the focus on thorium reactors has highlighted an opportunity for the United States to enhance its position in global energy markets, particularly in the context of competition with the People's Republic of China (PRC). The thorium fuel cycle (TFC), although originally developed in the U.S. during the 1960s, was eventually overshadowed by uranium-based reactor technology. As concern over nuclear proliferation increases, the importance of establishing clear parameters for the TFC becomes imperative. This not only relates to safety but also to the potential risks it poses regarding nuclear weapons development. The International Atomic Energy Agency (IAEA) has a crucial role in monitoring these developments. China has made significant strides in developing its molten salt reactors (MSRs), presenting a challenge to the United States, which is urged to re-invest in thorium technology, previously pioneered at Oak Ridge National Laboratory. By doing so, the U.S. can promote its technological standards to the Global South, ensuring its position as a leader in renewable energy while addressing concerns about proliferation. There is also a strategic aspect to U.S. engagement in thorium technology that aligns with a push for workforce modernization and the creation of high-skilled jobs in the emerging energy sector. The U.S. must address its domestic thorium reserves and potential risks associated with political dynamics in the Russian Federation, which is a primary supplier of low-enriched uranium. In doing so, the U.S. can leverage the current research and development facilities and consolidate its efforts toward a transition away from uranium-based systems, potentially gaining sustainable energy independence. This initiative supports long-term economic ambitions while re-establishing the United States as a competitive force in global energy innovation. Finally, to truly capitalize on the present moment, the U.S. must navigate the domestic and international landscape thoughtfully, fostering collaboration with international partners, particularly with regard to safety standards. Through these actions, the United States can solidify its soft power while paving the way for future advancements in energy technology, possibly making a significant impact on global policies regarding energy production and nuclear safety.
