@Walter Hinteler,
Thanks for the info. Macron will be long gone by 2035, so his promises must be taken with a grain of salt. Even closing down the oldest of French nuclear plants, Fessenheim, has been much easier said than done. It was promised for 2015, then 2018, and now they speak of 2020...
The EPR design has run into engineering problems and construction delays, costing billions of euros to Areva. If that design was seen as non-problematic, the French state would be heavily investing in replacement plants right now. It's only because we don't seem to have a functional design for the next generation of nuclear plants that we are now thinking about alternatives.
Not a second too late, IMO. Nukes are inherently risky and produce waste that's costly to manage.
