That's false too. Most of the arguments from antinuclear activists in this direction are about physical capacity of modulating too slow, which was false. Regardless, EDF is modulating now mostly due to economic reasons. Above 50-60% capacity factor you'll be fine, beyond that it'll be problematic with any asset, at which point you'll need to ask yourself if you love gas or you let nuclear run for some minimal CF or if you mandate each NPP to build a bess buffer to absorb capacity when needed
