Nuclear power is not a solution to climate change. It would bind too many resources (which are also finite in economical quantities). Last year the first permanent storage worldwide opened, it is not a solved problem. Nuclear processing plants have elevated cancer rates around their location and it is still legal to dumb contaminated water into the ocean. It was only restricted for barrels.

The construction costs are very relevant, not only from a CO2 perspective. Nuclear power is not very attractive, only if you reduce environmental protection to CO2 output, which is insufficient. So no, the greens of former years were not that wrong. It is questionable to shut down working plants, but if nuclear was that feasible, it would already play a larger in energy production today. If you start building plants today, you will need at least a decade to get them operational. You can look at France for the youngest examples of that.

And would you want to mine Uranium? Have fun with that.
