France has 58 reactors with combined power of 60GW. The audit in 2011 (after Fukushima) estimated their cost at 96B euros and the total investment into the nuclear industry since 1950 including research at 228B euros.

And that doesn't include the fact that for all these years electricity prices in Germany were higher than in France which helped to keep renewables afloat.

> But renewables are far cheaper than nuclear in the 2020's.

That's yet to be seen, doesn't really match the reality I observe so far. They are promised to be cheaper sure, but you end paying more and subsidizing coal power plants in China along the way.
