So the man-made disaster consisted in allowing to build something like this in an area where there are earthquakes so big.

Man made disaster is the prices for electricity we pay in Germany, while France is happy generating nuclear power and pays 30% less.

A state law (2015-992, from 2015, the "loi relative à la transition énergétique pour la croissance verte") states that the part of nuke-produced electricity must fall to less than 50% in 2025, from 72% then, and that renewables must replace it.

In France nuke-power is backed by gas (which produced 10,3% of gridpower in 2017).

The sole reactor currently planned (Flamanville-3) is a complete disaster, more than 10 years behind schedule and 4x overbudget. https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan...
