Nuclear vegetation too costly? China reveals low-cost building attainable

As nations race to scale up nuclear energy to satisfy local weather targets and gasoline power-hungry knowledge facilities, a longstanding drawback persists: Nuclear vegetation are notoriously costly to construct. But China is providing the world a lesson in curbing prices.

While nuclear vegetation have turn out to be more and more costly within the United States and France, in China, building and working prices are dramatically much less, discover researchers from Johns Hopkins University, Harvard, CUNY, and Stony Brook University. The group compiled and analyzed new knowledge to indicate how China has decreased nuclear building prices over time although a combination of standardized designs, strategic indigenization of provide chains, and coordinated industrial coverage.

In the U.S., common prices in the present day for brand new nuclear vegetation might be as excessive as $15/watt, whereas the most recent French vegetation prices over $4/watt, based on the authors. But the present price of the extremely standardized Chinese-designed vegetation are half that, or about $2/watt, the group discovered.

“This is an exciting three-country comparison of data and trends which follows a model we first tried back in 2007 when we could only access data for the ‘fleet’ of 103 U.S nuclear plants at 67 sites. Now we can look globally and update our approach at a time when many nations in both industrialized and industrializing regions are taking a deep, second, look at nuclear power,” says creator Dan Kammen, the Bloomberg Distinguished Professor of Energy and Climate Justice at Johns Hopkins.

The analysis appears today in Nature.

The authors warning that nuclear energy remains to be not low cost, however say China’s expertise affords a precious playbook for different nations aiming to deploy nuclear power affordably and at scale.

“Globally, the more nuclear we build, the more expensive it’s gotten,” says Shangwei Liu, lead creator and a researcher at Harvard’s Kennedy School. “But in China we see the opposite: a carefully sequenced strategy that is driving costs down—not just through technology, but through policy, institutions, and supply chain coordination.”

Keys to China’s success, the authors say, are predictable regulation, staged indigenization of producing, and long-term planning.

“Substituting expensive imports with domestically produced components substantially lowered costs,” says Gang He, assistant professor on the Marxe School of Public and International Affairs at CUNY’s Baruch College. “Strategic indigenization may be the key not only for nuclear, but for other clean technologies in countries seeking to scale up rapidly.”

The authors name on researchers, policymakers, and business leaders to keep away from repeating previous errors, similar to abandoning standardized designs or dashing to localize advanced methods, earlier than home capabilities are prepared. They argue for deeper component-level price evaluation and higher alignment between security and value management in regulatory methods.

“Countries that export nuclear technology should collaborate with importing ones to identify components that can be locally manufactured and train the workforce,” says Minghao Qiu, an assistant professor at Stony Brook University.

As curiosity in small modular reactors grows and new nations enter the nuclear area, the authors urge decision-makers to study from each success tales and setbacks.

“China shows that nuclear power construction and operational costs early in the life of a reactor don’t have to rise and rise,” says Kammen, who additionally performs a management position in Hopkins’ Ralph O’Connor Institute of Sustainable Energy. “But breaking the cost curse will take more than technology—it will take a smart and strategic approach. A key question for future research and practical demonstration is what happens to the costs—and the risks—of nuclear power when plants age and end-of-life and decommissioning costs must be addressed.”
