China’s Energy Singularity Makes Fusion Energy Breakthrough

Energy Singularity announced that the Chinese nuclear fusion energy startup has made a significant breakthrough in the field of high-temperature superconducting magnets and set a magnetic field record in the process.

The Shanghai-based company said today that its state-of-the-art large-bore high-field magnet, named Jingtian, has successfully completed its first experiment, generating an unprecedented 21.7 tesla magnetic field. That set a new record for large-bore D-shaped HTS magnets.

The previous record of 20.1 tesla, set in 2021, was achieved by the SPARC TFMC magnet jointly developed by the Massachusetts Institute of Technology and US fusion energy company Commonwealth Fusion Systems.

Xinhua News Agency, Fuzhou, April 8 (by reporter Wu Jianfeng) -- At 6:16 a.m. on April 8, the hot functional testing for Unit 2 of the Zhangzhou nuclear power plant under CNNC's Hualong One batch construction project was successfully completed, laying a solid foundation for subsequent nuclear fuel loading and grid-connected power generation.

The hot functional testing involves comprehensive trials conducted through main pump operation and pressurizer electric heater activation to elevate temperature and pressure within the reactor coolant system. These tests, executed across specific experimental platforms during simulated operational conditions, verify the performance of nuclear island and conventional island equipment systems under thermal operation.

As the inaugural site for Hualong One's batch construction and currently the world's largest Hualong One nuclear power base, the Zhangzhou project plans to construct six Hualong One nuclear power units. Unit 1 has already commenced commercial operation, while Unit 2 is scheduled to achieve commercial operation in the fourth quarter of this year. Construction of Units 3 and 4 commenced in 2024, with preparatory work for Units 5 and 6 progressing in an orderly manner.

Are these of the new Thorium types? If not, and they are the traditional types, I question the strategic wisdom of keeping them so close to the shore.

China tops global rankings in overall nuclear power scale for first time

As of now, China has 102 nuclear power units, including those in operation, under construction and approved for construction, with a total installed capacity of 113 million kilowatts, ranking first globally, in terms of the overall scale, for the first time, according to a blue book - China Nuclear Energy Development Report 2025, the Global Times learnt from the China Nuclear Energy Association (CNEA) on Sunday.

As of the end of 2024, China had 28 nuclear power units under construction, and the installed capacity of the units under construction has held the top spot globally for 18 consecutive years, according to the blue book.

For the first time, China has taken first place in the world in terms of installed capacity of nuclear power plants: in total, the country has 102 nuclear power units in operation, under construction and approved for construction, with an installed capacity of 113 million kW.

With China’s State Council approving 10 new nuclear reactors to add to the 30 under construction, this is the fourth year in a row that China has approved at least 10 new reactors. China has 30 reactors under construction, nearly half the world’s total, and is expected to surpass the United States as the world’s largest producer of nuclear power by the end of the decade. Four of them have been ordered by China General Nuclear Power Corp. for installation at its plants in Fangchenggang and Taishan. China National Nuclear Corp., State Power Investment Corp. and China Huaneng Group Co. have each received approval for two reactors. China has doubled its number of reactors in the five-year period that is now ending. This is unprecedented communist construction. The fact that 10 more reactors have been added in the current period almost certainly indicates a massive plan to double the number of nuclear plants again. In other words, China’s share of nuclear power will grow to the Russian level (about 20 percent) or even follow the French model (70 percent). This is 100% likely to happen.

The Chinese are building nuclear power plants approximately 1.5 to 2 times faster than Russia and the US, showing that they are urgently reducing their dependence on hydrocarbons, especially those that come by sea. In other words, it is a strategic response to a potential naval blockade.

Traditional types need massive amount of water for cooling so they're always built near large bodies of water, most often near the shore. It's also where the demand is at.

We can expect 10 reactors per year for some time yet.
The 15-year plan requires about 150 reactors, which is 10 per year.
That is about 200GW which translates to about 1700 TWh of electricity per year.

So in 2035, this additional nuclear capacity would be about 15% of total electricity consumption in China
