You can't just invent a number because you like it more. Solar and Wind are cheaper than nuclear even if you go beyond LCOE and include system costs. Even the nuclear lobby acknowledges this nowadays and has switched to other arguments.

No.

Not even close. Wind and solar are cheap _only_ if you don't depend on them. In particular, for the wind the adequacy rating is about 10% in most places. It means that you can expect 10% of the nameplate capacity to be available at all times system-wide. So multiply the wind energy costs by 10x, and suddenly they are quite more expensive than nuclear.

It's not even a question for the solar, it simply can't provide power during a day without storage.

Nope.

First, capacity factor is a silly metric to use for this. The industry uses LCOE or system LCOE, because this is about dollars per actual TWh produced, not capacity. In other words: A capacity factor of 10% doesn't matter if building 10x the amount is still cheaper.

With that said, the wind capacity factor in Germany is 20% for onshore and 40% for offshore, so even that was wrong by a factor of 2-4.
