Now you are just throwing everything at the wall and hope it sticks. You're essentially shifting to a "sure, reactors are expensive, but the whole-system price is lower" argument.
Well, we'll see, I guess.
Yes, Germany is going to spend about €600 billion in infrastructure. That has more to do with electrification than renewables - France too need another €250 billion for grid upgrades until 2045.
As for the "6+8" program - EDF still hasn't produced an official cost estimation for the for the full fleet and the original estimate for the first six (€52 billion) is has already been pushed upward to €72.8 billion.
Electricity prices in France have for a long time been a political matter, not market decision. That's a different approach than that of Germany, so the two really cannot be compared.
