Refurb costs are for the entire fleet which is 50+GW and are in fact dirt cheap. Refurbs are in 1-3bn/unit range. CF of say solar in this region is roughly 10-12%. To have same average output as a single 1GW npp you would need about 10GW solar and much more if you want to achieve firm generation. French refurbs will happen anyway. In fact, carenage is already undergoing.
