France in the end of the 60's nuclearized its gridpower production.
This 'success story' led to a state law (2015-992, from 2015, the "loi relative à la transition énergétique pour la croissance verte", see https://www.legifrance.gouv.fr/loda/id/JORFTEXT000031044385/... ) stating 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...
