I'm doubtful of that. One big root cause for most of the delays is the fact that no new reactor projects were started in a long time before this one, in Western regulation regimes. Due to this, a lot of cumulative experience was lost from the industry and the designs become outdated. For example all the previous designs relied on relay based automation, which is no longer available. Add to that the increasing demand of safety, necessitating way heavier structures and yet again obsoleting designs.

I would think building another one like this should be less of an ordeal. Too bad the sister project at Flamanville was started too early after this one to benefit from the lessons learned.
