that building nuclear power plants becomes increasingly cheaper

While Western countries debated for or against nuclear energy, with the construction of new plants weighed down by decades of delays and cost overruns, China has not only continued building: He has done it against the trend of the sector. For the first time in more than 50 years, a country has made building nuclear reactors increasingly cheaper, faster and scalable.

The difference is overwhelming. The only two reactors built in the United States this century (at the Vogtle plant in Georgia) took 11 years to complete and cost a whopping $35 billion, equivalent to about $15 per watt of capacity. According to a analysis published in NatureChina is building its new nuclear power plants for just $2 a watt.

It is not an anomaly, but a trend. Construction costs in the United States have increased tenfold since the 1960s, and in France they have almost doubled. In China they halved during the 2000s and have remained stable since then. The big question is how they have achieved it, and whether the rest of the world can imitate them.

The Chinese nuclear recipe. Building a nuclear power plant remains one of the most complex engineering projects on the planet. If China has managed to do this in an increasingly efficient way, it is thanks to a mix of standardization and unwavering state support. The three state nuclear giants receive low-interest loans, which greatly reduces the cost of financing.

Unlike the West, where each project has been a new experiment with unique designs, China has often focused on building a handful of models, scaling its nuclear capability rapidly. But these are just the last steps of the recipe. To get here, Beijing had to invest in mastering each link in the supply chain.

Made in China. As detailed in a extensive New York Times reportthe country has developed a robust national industry capable of forging everything from reactor vessels to the most critical components of each nuclear power plant. Components made in China, such as cargo pumps or ring cranes, cost half as much as their imported equivalents.

A perfect example is the American-designed AP1000 reactor. Both the United States and China faced enormous challenges building this model. But as problems led to delays and skyrocketing costs that nearly buried the American industry, China paused, studied every flaw, and ended up developing an improved, nationalized version of the reactor: the CAP1000. It is now building nine reactors of this model within just five years, and at a drastically lower cost.

The winning strategy. “China demonstrates that the construction and operation costs of nuclear power do not have to increase unabated,” explains Dan Kammenprofessor at Johns Hopkins University. Breaking the curse of cost overruns requires “more than technology: it requires an intelligent and strategic approach,” says Kammen.

The result of this approach is that China is on track to overtake the United States as the largest nuclear power in the world in 2030. Today it has almost as many reactors under construction as the rest of the world combined. It is not a simple bet, but a State policy that does not end at its borders. China has already put two Hualong One reactors into operation in Pakistan, and has plans to continue expanding throughout Asia, Africa and South America.

Waiting for the SMR. While China perfects the construction of large already proven reactors, Western countries follow a radically different path: betting on innovation through the private sector. Dozens of startups are working on a new generation of small modular reactors (SMR), theoretically cheaper and faster to build.

Tech giants like Google, Amazon and Microsoft They have invested billions in them to power their energy-hungry data centers. The problem is not only that This technological advance will take years to maturebut China does not live apart from it. The country is already taking giant steps in future technologies, such as fourth-generation gas-cooled reactors or research into thorium reactors. And he could repeat the same strategies that have worked with traditional reactors.
