While I respect Jérôme's expertise, and his views, I think there is a factor he is neglecting (not his sector) the emergence of hydrogen as the dominant freight transport fuel (and in other industrial roles) in coming decades.
Large-scale electrolysis plants to produce hydrogen will need to adapt their production according to the availability of electricity (because hydrogen is stored energy); this means they are highly compatible with the intermittence of renewables, BUT also that they would produce more optimally on baseload. So new nuclear may well be back on the table.
