Which is to be expected when you build a massively centralized, both physical and organisational, power system.
And which is my main issue with nuclear power: it isn't distributed, but centralized and heavily dependent on governments and extreme long-term-planning. Which is a recipe for disaster. The chance that Flamaville would be delivered late is about 100%. Reacting to rapid changes like a war (spiking fuel prices or making NG unattainable) always slow, and always late if possible at all.
So, aside from all the other arguments against nuclear power, it is slow, expensive, centralized and heavily dependent on governments; it's the closest you'll get to a government-ran electricity production. All of which make me wonder every time why the European left (pro- government) are against it, but the right (market liberalism) love it. It should be the exact opposite.
The entire opposite is solar: heavily distributed, privately owned and immensely fast. Wind is somewhere in-between, cheaper and faster to build than a CHP, but obviously more centralized than solar.
