Renewables crash the money making potential of nuclear power. Why should someone buy ~18-24 cents/kWh new built nuclear power excluding backup, transmission costs, taxes, final waste deposit etc. when cheap renewables deliver?

China is barely building nuclear power, in terms of their grid size. It peaked at 4.6% in 2021, now down to 4.3%.

Compared to their renewable buildout the nuclear scheme is a token gesture to keep a nuclear industry alive if it would somehow end up delivering cheap electricity.

nuclear provides for about 4-5ct/kwh if built cheap, everything included, looking at swiss data. Chinese units are built for 2.5bn/unit, so probably even cheaper than that. But yes, china is far from what france or sweden did with nuclear per capita

Again they aren't the same product. Everyone always thinks power is only about $/kwh especially in hackernews. That is a strong proponent of the product but most definitely not all of it. Solar just does not work for large scale industrial uses cases (99.99% uptime). Even with massive energy storage to try and cover the edges. Its a great combo but not comparable.

How does your "large scale industrial use case" deal with 50% of the French nuclear fleet being offline?

Or 50% of the Swedish fleet two times this year being offline?

At the same time it happened, the french solar was 92% offline and the french wind generation was 81% offline.

Maybe we should get the opposite conclusion from this incident.

Based on yearly average capacity factor?

Since that incident storage has been scaling massively. How does a nuclear plant compete with zero marginal cost renewables?

by providing firm power.

Based on if it would run at full capacity like a plant would yes.

And no, storage hasn't scale at all yet, it would need a 100x increase before being useful for such events.

The proof is in the pudding anyways, if that works so well, why nobody does it?

Nobody does what? Solar installs are way way up.

Nobody does a storage based solar grid at a country scale.
