China has been the second largest producer of nuclear energy since 2020:

Think it comes down to France using some nuclear reactors not just for baseload (100% operation while available) but also for balancing power.

As for becoming #1, it looks like the current batch of constructions will more or less achieve that, which should be around 7 years:

China is number one if you count units under construction.
China's overall nuclear power footprint, including units both in operation and approved for construction, has reached a world-leading 125 million kilowatts, driven by a rising number of new projects, according to an industry blue book released on Friday.

近日,中核集团中国原子能科学研究院自主研制的国内首台 10MeV 超紧凑医用回旋加速器成功出束,各项关键指标均达到设计要求。该加速器具备氟-18、镓-68、碳-11 等多种常用短寿命医用同位素的生产能力,所产同位素作为核医学诊断的显像剂,可实现肿瘤病灶的精准识别与早期诊断。
CNNC developed China's first 10MeV ultra-compact medical cyclotron. Capable of producing variety of commonly used short-lived medical isotopes, including Fluorine-18, Gallium-68, and Carbon-11. When utilized as imaging agents in nuclear medicine diagnostics, these isotopes enable the precise identification and early-stage diagnosis of tumor lesions.

Approved and under construction is not the same as under construction.

You're misconstruing an already terribly misleading article, containing blatant falsehoods like: With this robust pipeline, China's operational nuclear capacity is expected to surpass that of the United States before 2030, making it the world's largest

Which we know isn't true because there's no reactor design that is built in less than 4 years, meaning no reactors not currently under construction will be completed by 2030...

Something something overcapacity lol.

China has announced that it now has the capacity to build up to 50 nuclear reactors simultaneously, as it doubles down on a push to rapidly expand its nuclear power generation and become a global leader in the sector. The figure came from a report released by the China Nuclear Energy Association (CNEA) on Friday, which highlights the country’s ability to run dozens of nuclear projects concurrently spanning the full project life cycle – from design to construction.

The country already has 60 nuclear reactors in commercial operation and another 36 under construction, which represents more than half of the total number of reactors currently being built globally, the report shows. Chinese authorities have also approved 16 reactors for future construction. Once all those projects are completed, China’s installed nuclear power capacity will reach 125 gigawatts (GW), according to the report. By 2040, China is projected to have 200GW of installed capacity, Yang Changli, rotating chairman of the CNEA, told domestic media outlet chinanews.com.cn.

...

China has announced that it now has the capacity to build up to 50 nuclear reactors simultaneously
This may seem like a high number but considering it takes 5 years to build a nuclear power plant
this comes out to on average 50 / 5 = 10 nuclear reactors per year
at 1.2GW each x 10 = 12 GW per year
at this rate it's going to take 100 years to replace China's coal power plants with nuclear.
This is too long.

Granted China deserves credit for building greater nuclear capacity compared to the rest of the world combined.....but this is not enough. More needs to be done. One may ask why should China carry this burden? The simple answer is because the rest of the world cannot. Only China can do this. I predict China will eventually increase it's capacity from building "50 nuclear reactors simultaneously" .....to 200.

Maybe there is no need to replace the coal power plants?

As terrible as this sounds for the environment I have to agree with you, from an energy security standpoint coal is indispensable, China has massive reserves (170 billion tons) and even in the unlikely scenario that they start dwindling Russia has even larger coal reserves (178 billion tons). And even in the worst case scenario where new deposits do not become viable and coal use remains at the current levels (4-5 billion tones per year) the reserves won't be depleted until the 60's. Until Fast Breeder Reactors, Thorium reactors and reprocessing facilities can be built at scale there is little incentive to fully phase out coal from the energy security standpoint.
