It is not like nth of a kind Hinkley Point C, EPR reactor number 5 and 6, at $32.5B per reactor is going any better?
Also do note that no one knows the true cost of Olkiluoto 3. The $11B figure is from a settlement many years before it was completed as interest and construction costs kept accumulating.
It is probably infuriating to many that costs are that significant and that important. France should be the model for nuclear, but mismanaged EDF which now has €54.3 billion debt and is years behind in maintenance. (2022 debt was €64.5 billion). And the public and politicians pitch a fit if the PM proposes a balanced budget with cuts. Nuclear doesn't make the cut when there are multiple competing interests of nitwits.
