At the start of construction, Hinkley Point C is estimating €8.1/W. This is still four times the initial estimates cost for Flamanville 3, €2/W. But it's a bit less than the current estimated cost of Flamanville 3, €11.5/W.
However this is all assuming that Hinkley Point C stays in budget and on schedule, which would be a strange assumption to make given recent history.
So I'm not sure anything is being learned, or construction capability is increasing. Which is a shame, because that area of the world is the area with the strongest need for nuclear. The rest of the world will get by fine without it. And for that matter, it's likely that Northern Europe can build enough wind and storage to get around their need for nuclear. But it all would have been a lot easier if the nuclear industry was anywhere close to delivering on its lofty promises.
