How The U.S. Fell Behind China On Nuclear Power
The United States, once a leader in nuclear energy, has significantly fallen behind China in developing and deploying new nuclear power plants. China is rapidly expanding its capacity with state-backed projects and advanced reactor designs.

The article details the contrasting trajectories of nuclear power development in the US and China. Decades of stagnation due to accidents and economic factors have hampered US progress, while China's centralized planning and aggressive investment have propelled it to the forefront of global nuclear expansion, posing geopolitical and energy security implications.
Imagine building a giant LEGO castle. America started first and built some big ones, but then had some problems, like a few blocks falling off, which made everyone nervous. So, America stopped building new castles for a long time. Meanwhile, China watched, learned, and then started building lots of new, super-fast LEGO castles, all using the same easy-to-build plans. Now, China has many more new castles, and America is trying to catch up by designing smaller, smarter LEGO sets.

Three Mile Island
The trajectory of nuclear power in the United States was significantly altered by the 1979 Three Mile Island accident. This incident, though not resulting in any fatalities, severely eroded public trust in nuclear technology and led to a dramatic increase in regulatory scrutiny. The heightened safety requirements and public opposition contributed to a de facto moratorium on new reactor construction for decades, effectively stalling the growth of the US nuclear fleet.
Following Three Mile Island, the US nuclear industry faced escalating costs and prolonged construction timelines, making new projects economically unviable. The regulatory environment became increasingly complex, adding layers of approvals and oversight that further deterred investment. This period of stagnation allowed other nations, particularly China, to develop more streamlined and cost-effective approaches to nuclear power expansion.
China's 70 GW Target
China has set ambitious goals for its nuclear energy program, aiming to reach 70 gigawatts (GW) of operational capacity by 2025 and 180 GW by 2035. This aggressive expansion is driven by a state-led strategy that prioritizes standardized designs, domestic supply chains, and rapid construction. Currently, China boasts 55 operational reactors and has an additional 22 under construction, far outpacing the US, which has 93 operational reactors but only two new units being built.
The Chinese approach leverages economies of scale and a centralized decision-making process to overcome the cost and time overruns that plague Western projects. By focusing on indigenous reactor designs like the Hualong One and exploring advanced technologies such as high-temperature gas-cooled reactors (HTGRs), China is not only meeting its domestic energy needs but also positioning itself as a major exporter of nuclear technology. This strategic advantage has significant geopolitical implications, as China can offer competitive nuclear solutions to developing nations.
Small Modular Reactors
In an effort to revitalize its nuclear industry, the United States is now focusing on the development of Small Modular Reactors (SMRs) and other advanced reactor designs. These smaller, factory-built reactors promise lower costs, faster construction, and enhanced safety features, potentially addressing many of the issues that hindered previous large-scale projects. The US government and private companies are investing in research and development to bring these innovative technologies to market.
However, the path to widespread SMR deployment in the US faces considerable challenges, including regulatory approval, securing initial funding, and establishing a robust supply chain. While SMRs offer a promising future for nuclear energy, the US must overcome decades of underinvestment and rebuild its industrial capacity to compete effectively with China's established and rapidly expanding nuclear infrastructure. The success of SMRs is crucial for the US to regain its competitive edge in the global nuclear power landscape.
Key points
- The US nuclear power generation peaked in 2012, with only two new reactors currently under construction.
- China is rapidly expanding its nuclear capacity, aiming for 70 GW by 2025 and 180 GW by 2035, with 55 operational and 22 under construction.
- Accidents like Three Mile Island and Chernobyl led to public distrust and stringent regulations, hindering US nuclear growth.
- China's state-led approach, standardized designs, and domestic supply chains enable faster and cheaper reactor construction.
- The US is now focusing on Small Modular Reactors (SMRs) and advanced designs to revive its nuclear industry.
- China's dominance in nuclear technology has significant geopolitical implications, including its ability to export reactors.
The US focus on Small Modular Reactors (SMRs) and advanced designs could lead to a resurgence in its nuclear industry, offering a more cost-effective and flexible energy solution. Successful deployment of these technologies could help the US meet its clean energy goals, reduce reliance on fossil fuels, and regain a competitive edge in global nuclear technology exports.
The US faces significant hurdles in scaling up its nuclear capacity, including high construction costs, complex regulatory processes, and a lack of a robust domestic supply chain. Without substantial and sustained investment, the US risks falling further behind China, potentially impacting its energy security and geopolitical influence in the global energy market.
