The costs are high because noone is building. It's because of all the building that solar is low. If you started building npps the costs would go down a lot.

France built out nuclear and the costs kept rising. Not every learning curve is positive.

  Wrong according the parent comments' source. > Not every learning curve is positive. It should be, if it's not then someone is fucking up and that fuck up needs to be fixed, rather than giving up on the entire project.

If you look at the data in the link I posted above, it shows exactly the opposite. Nuclear gets more expensive per capacity built.

  From your source, it's not as simple as you state: > One reason for rising prices is increased regulation for nuclear power, which has the important benefit of increased safety. A second reason is that the world has not built many nuclear power plants in recent years so that supply chains are small, uncompetitive, and are not benefiting from economies of scale.35 > Both of these reasons explain why the global average LCOE price has gone up. But for nuclear there are large differences in price trends between countries: Prices and construction times have increased significantly in the US and the UK, while France and South Korea were at least able to keep prices and construction times constant.36 > Michel Berthélemy and Lina Escobar Rangel (2015) explain that those countries that were able to avoid price surges are countries that do not stand out in regulating nuclear power less, but in standardizing the construction of reactors more.37 Learning, after all, means transferring the knowledge gathered in one instance to another. No repetition, no learning. > This is in sharp contrast with renewables in particular. While nuclear technology is not very standardized and gets build very rarely, solar PV modules and wind plants are the exact opposite, very standardized and extremely often built.
