If you believe China's internal pricing numbers, sure....

But their actual investments in billions of dollars and in GW show that nuclear is not competing with solar, and is sticking around for hedging bets. They the are deploying far far far more solar and storage than nuclear. And if those nuclear costs were accurate, then nuclear would be far preferable. $2/W is incredible, as in perhaps not credible, but it would also be far cheaper than solar.

And even if China figured out how to build that cheaply, it doesn't mean that highly developed countries will be able to replicate that. Nuclear requires a huge amount of high skill, specialized labor, and doing that cheaply is only possible at certain levels of economic development. As economies develop to ever higher productivity, the cost of labor goes up, and it's likely that nuclear only ever makes sense at a very narrow band of economic development.
