Anyone who tries something like that in the PRC would end up getting harvested for body parts.
The sole imperative of a government, once instituted, is to survive.

China to Use First Atomic Icebreaker as Test for Future Nuclear Aircraft Carriers

A nuclear icebreaker will further enhance China’s ability to navigate the Arctic Ocean even during winter. With a displacement of more than 30,000 tons the proposed vessel will be just slightly smaller than Russia’s newest and largest icebreakers of the Arktika class.

China’s plans to build a nuclear icebreaker are just the latest step in its efforts to pursue a more active role in the Arctic. The country released its first-ever Arctic policy in early 2018 followed by the launch of its second conventional icebreaker in September. About two dozen Chinese vessels transited Russia’s Northern Sea Route in the last five years, more than any other country except Russia. It is also a large investor in Novatek’s Yamal LNG, a major natural gas project.

“This will now give the Chinese the ability to go anywhere at any time. The size of the icebreaker, if indeed reports are accurate, means China will have a capability that will rival Russia’s icebreakers,” explains Rob Huebert, associate professor at the University of Calgary and a senior research fellow with the Centre for Military and Strategic Studies.
Icebreaker paves way for aircraft carrier

But there is another, more long-term and strategic aspect to building this icebreaker. China will be able to draw valuable lessons from designing, constructing, and operating a nuclear icebreaker. “The use of a nuclear icebreaker can be understood as laying the foundation for the future acquisition of nuclear-powered aircraft carriers,” states Aki Tonami, Arctic researcher and Professor at the University of Tsukuba in Japan.

Just more "hyperbole" I suppose.  ::)

"DARPA Hard"  It ain't what it use to be.

What could the Chinese learn from operating a reactor on a ship,  that they can't from operating one on a submarine?

How to deal with the fact that 'make depth 200 metres' isn't an acceptable solution to heavy weather, for one thing. Probably also issues around higher-power reactors, and the interaction between a nuclear plant and surface ship auxiliary systems. The duty cycles will be different for a surface ship than a submarine, which may well throw up issues that it's worth discovering ahead of time.

Thanks, a heavily rolling/pitching ship may indeed pose some challenges to the reactor related systems.

There's also the need to see how well the nuke construction knowledge base, which up till now has been concentrated mostly at Bohai, can get out to other shipyards if they intend to produce nuclear carriers without disrupting submarine work.
