[–><!–>China is quickly becoming the global leader in nuclear power, with nearly as many reactors under construction as the rest of the world combined. While its dominance of solar panels and electric vehicles is well known, China is also building nuclear plants at an extraordinary pace. By 2030, China’s nuclear capacity is set to surpass that of the United States, the first country to split atoms to make electricity.–> <!–>

[–><!–>As the United States and China compete for global supremacy, energy has become a geopolitical battleground. The United States, particularly under President Trump, has positioned itself as the leading supplier of fossil fuels like oil, gas and coal. China, by contrast, dominates the manufacturing of solar panels, wind turbines and batteries, seeing renewable power as the multi-trillion-dollar market of the future.–> <!–>

[–><!–>The Trump administration wants to quadruple U.S. nuclear power capacity by 2050, even as it ignores global warming, and it hopes to develop a new generation of reactor technology to power data centers at home and sell to energy-hungry countries overseas. Officials fear that if China dominates the nuclear export market, it could expand its global influence, since building nuclear plants abroad creates deep, decades-long relationships between countries.–> <!–>

[–><!–>While U.S. nuclear construction costs skyrocketed after the 1960s, they fell by half in China during the 2000s and have since stabilized, according to data published recently in Nature. (The only two U.S. reactors built this century, at the Vogtle nuclear plant in Waynesboro, Ga., took 11 years and cost $35 billion.)–> <!–>

[–><!–>The fact that the Chinese government has a national mandate to expand nuclear power means that companies can confidently invest in domestic factories and a dedicated engineering work force. In a sprawling complex near Shanghai, giant reactor pressure vessels are being continuously forged, ready to be shipped to new projects without delay. Teams of specialized welders move seamlessly from one construction site to the next.–> <!–>

[–> <!–>
–><!–>
[–><!–>In the 1970s and 1980s, U.S. nuclear construction slowed to a trickle as interest rates rose and regulators frequently tightened safety rules, causing delays. Worries about the disposal of nuclear waste and fears after the 1979 partial meltdown of a reactor at Three Mile Island, in Pennsylvania, didn’t help. At the same time, private developers kept experimenting with new reactor designs that required different components and introduced fresh complications. U.S. nuclear power died from a lack of predictability.–> <!–>
–><!–>
<!–>
–><!–>
–><!–>
[–><!–>The contrast became glaring in the late 2000s, when U.S. utilities tried to revive nuclear power with a new reactor model called the AP1000, with improved safety features. Developers struggled with the novel technology, leading to repeated delays and soaring costs. By the time the two reactors in Georgia were finished last year, most utilities were hesitant to try again.–> <!–>
–><!–>
[–><!–>As it happened, China built AP1000s at the same time. It, too, faced severe challenges, such as difficulties in obtaining coolant pumps and unpredictable cost spikes. But instead of giving up, Chinese officials studied what went wrong and concluded they needed to tweak the design and develop domestic supply chains.–> <!–>
–><!–>
[–> <!–>

[–><!–>China is now building nine more copies of that reactor, known as the CAP1000, all on pace to be completed within five years at a drastically lower cost, an Energy Department report found.–> <!–>

[–><!–>China’s safety requirements are similar. But in China the approval process is more predictable, and opponents have fewer ways to challenge a project. Most reactors in China break ground weeks after receiving final approval from the safety regulator, according to research by Ms. Jiang. In the United States, by contrast, projects often need additional permits from state governments that can take months or years.–> <!–>

[–><!–>China’s nuclear expansion still faces hurdles. One of China’s plants suffered a smaller radioactive leak in 2021, and a bigger accident could trigger a public backlash. The country is still figuring out where to bury its nuclear waste, and some cities have seen impassioned protests over plans for waste reprocessing plants. Beijing has also blocked new reactors in much of China’s interior over concerns about their water use. If that moratorium persists, it could limit the industry’s growth.–> <!–>

–>Can the U.S. catch up?<!–>

[–><!–>In the United States, nuclear power is one of the rare types of energy that has support from Republican and Democratic politicians alike, especially as demand for electricity rises. Even environmentalists like Al Gore who once fretted about catastrophic accidents and radioactive waste are warming to the technology.–> <!–>

[–> <!–>

[–><!–>Dozens of start-ups are working on a new generation of smaller reactors meant to be cheaper than the hulking plants of old. Tech companies like Google, Amazon and OpenAI are pouring billions into nuclear start-ups like Kairos Power, X-Energy and Oklo to help power their data centers for artificial intelligence. Early projects are underway in Wyoming, Texas and Tennessee, though few, if any, new reactors are expected before the 2030s.–> <!–>
–><!–>
[–><!–>The Trump administration wants to accelerate this work by reducing regulations at the Nuclear Regulatory Commission, which certifies the safety of reactors before they are built. The agency’s critics say it has become too hidebound to handle advanced reactors that are less prone to meltdowns.–> <!–>
–><!–>
<!–>
–><!–>
–><!–>
[–> <!–>
–><!–>
[–><!–>Yet some worry that the United States is betting too heavily on technological breakthroughs instead of focusing on the financing, skills and infrastructure needed to build plants, as China has. The U.S., for instance, has lost almost all of its heavy forging capacity to make large reactor components. A new generation of advanced reactors could also take years to perfect, leaving America behind.–> <!–>
–><!–>
[–> <!–>
–><!–>
[–><!–>While the Trump administration has moved to speed up nuclear permitting and increase domestic supplies of nuclear fuel, some important government tools for advancing new reactors, such as the Energy Department’s loan office, have been hampered by staffing cuts. Efforts to slash safety regulations could be contentious. There is also a risk that interest by tech giants could fizzle if the A.I. boom slows.–> <!–>

[–><!–>China’s fast-paced nuclear program is a prelude to a larger goal: dominating the global market. Chinese companieshave already built six reactors in Pakistan and plan to export many more.–> <!–>
–><!–>
[–><!–>At the same time, China is working to surpass the United States in technological innovation. China has built what it calls the world’s first “fourth generation” reactor, a gas-cooled model that can provide heat and steam for heavy industry in addition to electricity. The Chinese are also pursuing technologies that use less uranium, such as thorium reactors, or recycle spent nuclear fuel. It’s a recognition that China doesn’t have enough domestic uranium for a massive build-out of traditional reactors.–> <!–>

[–><!–>Even if U.S. companies and labs remain at the forefront of innovation, one recent report warned that China was 10 to 15 years ahead of the United States in its ability to deploy next-generation reactors widely.–> <!–>
