Well, the Mankala model is not a problem. And most likely Olkiluoto 3 had a reasonable business case before the cost overruns. So the question is more or less:

Well, the Mankala model is not a problem. And most likely Olkiluoto 3 had a reasonable business case before the cost overruns. So the question is more or less: is the real price of nuclear the price that was hoped for Olkiluoto 3 or the actual price that will be paid? (maybe mostly by Areva and not TVO). The "strike price" of Hinkley makes me think that it is probably the latter. And while the trends look favorable for solar and wind, they seem less favorable for Nuclear - cf.
