China is building nuclear reactors faster than anyone else in history. It's not even a close race anymore. While the West gets bogged down in decades of permitting delays and massive budget overruns—looking at you, Vogtle in Georgia—Beijing is treating reactor construction like a factory assembly line. If you're asking is China nuclear power actually going to dominate the global energy landscape, the answer is increasingly looking like a "yes," but with some massive caveats that most people miss.
Nuclear energy isn't just a side project for them. It is the backbone of their plan to stop burning coal, which, honestly, they still do a staggering amount of.
Right now, the numbers are wild. China has about 56 operable reactors. That puts them neck-and-neck with France for the number two spot globally. But the real story is in the pipeline. They have nearly 30 more reactors under active construction. The International Atomic Energy Agency (IAEA) and the World Nuclear Association are basically tracking a new "first concrete pour" every few months. This isn't just about volume; it’s about the fact that they are building them in about five to seven years, while the U.S. and UK often take fifteen.
The Hualong One and the Pivot to Self-Reliance
For a long time, China was just copying homework. They bought technology from Westinghouse (the AP1000) and France’s Framatome (the EPR). They took those designs, pulled them apart, learned how they worked, and then built their own version: the Hualong One (HPR1000).
This is a big deal.
By creating a standardized, domestic design, they’ve eliminated the "first-of-a-kind" costs that kill nuclear projects in the West. When you build the same reactor ten times in a row, you get really good at it. Your supply chain stabilizes. Your workers don't have to learn new blueprints every time they walk onto a site.
Why standardization actually matters
Most people think nuclear power is expensive because the fuel is pricey or the tech is magic. It’s neither. Nuclear is expensive because of interest rates and construction time. If a project takes 15 years to build, the interest on the billions of dollars borrowed to build it ends up costing more than the reactor itself. By slashing construction times to under 70 months, China has basically cracked the code on making nuclear power economically viable without needing the level of massive, permanent subsidies that wind or solar often require for grid stability.

They aren't just sticking to traditional large-scale light-water reactors, either. In late 2023, China started commercial operations at the Shidaowan plant, which uses a High-Temperature Gas-Cooled Reactor (HTGR). It’s "pebble-bed" technology. Instead of long fuel rods, it uses hundreds of thousands of billiard-ball-sized graphite spheres filled with uranium. It’s cooled by helium, not water. This means it can’t "melt down" in the traditional sense because the physics of the pebbles limits the temperature naturally. It’s a Fourth Generation (Gen IV) reactor, and they got it running while the rest of the world was still debating the blueprints.
Is China Nuclear Power Safe? The Transparency Problem
This is where things get a bit murky. Whenever I talk to energy analysts about the Chinese program, the "S" word always comes up. Safety.
The China Energy Administration and the National Nuclear Safety Administration (NNSA) maintain that their standards are world-class. And to be fair, they have a clean record so far. They work closely with the IAEA. But the Western skepticism remains because, well, the Chinese political system isn't exactly known for its love of whistleblowers or open-source data.
In 2021, there was a minor "incident" at the Taishan Nuclear Power Plant. A few fuel rods were damaged, causing a buildup of radioactive gases inside the primary circuit. In the U.S. or France, this would be a routine maintenance issue. However, because the communication from the Chinese side was slightly delayed and felt "managed," it sparked international headlines. It turned out to be a non-event in terms of public health, but it highlighted the trust gap.
The regulatory speed trap
There is a legitimate question about whether the regulator can keep up with the builder. In most countries, the nuclear regulator is an annoying, slow-moving speed bump. That’s their job. They are supposed to be annoying. When you are building 10 reactors at once, can the inspectors really check every weld? Every valve? Every concrete pour?
Dr. François Morin, a director at the World Nuclear Association, has noted that China’s advantage isn't just cheap labor. It's the "fleet effect." They have a massive, permanent workforce that moves from site to site. In the U.S., we build a reactor once every thirty years, so we have to train a whole new generation of welders and engineers for every single project. China has a standing army of nuclear experts.

The Geopolitics of the "Nuclear Silk Road"
China doesn't just want to power Shanghai and Shenzhen. They want to export this stuff. They are already building reactors in Pakistan (Karachi and Chashma). They are looking at deals in Argentina, Turkey, and throughout Africa.
This is where the is China nuclear power question turns into a foreign policy headache for the West. Nuclear power plants are 60-to-80-year commitments. If a country buys a Hualong One, they are tied to Chinese fuel, Chinese software, Chinese technicians, and Chinese financing for the next three generations. It’s the ultimate "soft power" play.
Russia’s Rosatom currently dominates the export market, but China is catching up fast. While the U.S. is trying to get Small Modular Reactors (SMRs) off the ground with companies like NuScale, those projects have faced setbacks and cancellations. China, meanwhile, has already launched a floating nuclear power plant project and is moving forward with its own SMR, the Linglong One.
The Uranium squeeze
Here’s a detail people often miss: fuel. You can't run a reactor without uranium. China is aggressively buying up stakes in uranium mines in Namibia, Kazakhstan, and Canada. They are also building a massive national reserve. If they move to a closed fuel cycle—meaning they reprocess spent fuel to use it again—they could theoretically become energy independent for centuries. They are currently building a large-scale reprocessing plant in Gansu province. This is high-level chemistry that only a few nations can do.
What Most People Get Wrong About the Costs
You’ll often hear that Chinese nuclear is "cheap" because of "forced labor" or "low environmental standards." That’s a massive oversimplification. While labor is cheaper there, it’s not the main driver.
The real cost-saver is policy certainty.

In the U.S. or the UK, a change in administration can mean a complete 180 on energy policy. One year nuclear is "green," the next year it’s "dangerous." That uncertainty makes investors terrified. In China, the 14th Five-Year Plan explicitly lays out the nuclear targets. Banks (which are often state-owned) provide low-interest loans because the government has effectively guaranteed the project will finish.
If you want to understand the economics of is China nuclear power sustainable, you have to look at the "Levelized Cost of Electricity" (LCOE). For Chinese nuclear, it’s estimated to be around $40-$60 per megawatt-hour. In the West, for new builds, that number can easily double.
The Challenges Ahead: Water and Public Opinion
It’s not all smooth sailing. Most of China’s reactors are on the coast. They need seawater for cooling. But China’s inland provinces are desperate for power too. Building inland is harder because you have to worry about river water levels during droughts—something that has already plagued French nuclear plants during recent heatwaves.
Public opinion is also a factor. After the Fukushima disaster in 2011, China actually paused its program for a while to conduct safety reviews. There have been small-scale protests against nuclear waste facilities in places like Lianyungang. The government is sensitive to this. They know a major accident would not just be a tragedy; it would be a direct threat to the legitimacy of the party’s "green growth" narrative.
Actionable Insights for the Global Energy Market
Understanding the Chinese nuclear trajectory isn't just for academics; it has real-world implications for investors, policy-makers, and environmentalists.
- Watch the Supply Chain: If you are looking at the nuclear sector, realize that the supply chain is shifting eastward. Companies that provide specialized pumps, valves, and control systems are increasingly centering their operations near Chinese hubs.
- The SMR Race: The next five years will determine if the West can compete with Small Modular Reactors. If China successfully commercializes the Linglong One for export before Western firms get their first units online, the global market for "off-grid" or industrial nuclear heat will be theirs to lose.
- Uranium Demand: As China’s fleet grows, global uranium demand will remain structurally high. We are moving out of the era of "cheap, leftover Cold War fuel" and into a period of aggressive mining and exploration.
- Grid Stability Models: Engineers should look at how China is integrating nuclear with its massive wind and solar builds. Nuclear provides the "baseload" that renewables can't, allowing them to retire coal plants without risking blackouts.
China is currently on track to have the world’s largest nuclear fleet by 2030, surpassing the United States. They aren't doing it through a single "breakthrough" technology, but through the boring, relentless application of industrial scale and standardization. Whether the rest of the world follows their lead or tries to find a different path, the reality of the global energy transition is being written in the concrete of Guangdong and Fujian provinces.
