French lowered production capacity at the moment is largely due to delayed inspections because of Covid.
It's a very nuanced issue, I don't think it's very informed to say it's just due to delayed inspections... The inspections were what found cracks due to corrosion, repairs are taking really long.
And France currently shows that nuclear isn't really a good choice for base load since they had to restrict power output due to heat. The plants are getting older and require a lot of maintenance.
Energy production of the future should not concentrate on nuclear. It cannot compete on price and environmental factors in Europe. There are other places were it would fit better.
