On the very large scale is not as scalable with current technology compared to renewables, since the uranium runs out before access to sunlight runs out. Breeders are needed, and we have exactly two working commercial scale fast reactors in the world. For Japan alone that's not a problem though.

Not really the case. With reprocessing of current waste more fuel could be made easily.

And we could find more U-235 if demand really went up.

Reprocessing of thermal burner reactor fuel causes only a marginal extension of the uranium resource.

What would be needed are breeder reactors operating with a breeding ratio > 1. Otherwise, the vast majority of the 238U cannot be used.
