Anyway: those numbers are not "reactors likely reaching EOL". Those are reactors reaching the end of their original operating license.
These two things are not the same. At all.
Initial operating licenses were intentionally relatively short, because at the time there was no experience with the longevity of reactors. So you conservatively license towards the short end.
Now that we have that experience, reactor operating licenses are getting extended. A lot. The first reactors in the US have had their licenses extended to 80 years, and the current consensus appears to be that 100 won't be a problem.
So France won't be running low on nuclear power anytime soon. Unless you're Mycle Schneider and/or confuse "current operating license expiry" with "EOL".
So even to build the one Flamanville 3 reactor, they had to shut down two older reactors in Fessenheim in order to not have an illegal increase in capacity.
Now that the law has been rescinded, they are planning 6 simplified EPR2 reactors, taking lessons from the fairly catastrophic EPR project FV3.
(Of course, even that catastrophic reactor will be more profitable than any intermittent renewable projects in, for example, Germany, but hey, the standards for what counts as "success" and what as "failure" are different for nuclear and for renewables).
France also currently does not need to urgently expand their nuclear fleet, so the schedule for the EPR2s matches those needs and the need to fully account for the problems with FV3. Instead, they are increasing the production of their existing fleet, both by operational upgrades and also by increasing use of intermittent renewables to cover variations in demand, allowing the nuclear fleet to run closer to fully rated capacity instead of having to load-follow.
