When the Hinkley project in the UK was originally planned it probably looked like a much better calculation. Renewables were still expensive then. Oil prices were heading over $100/barrel - with no reason to believe they would drop. There was a lot of hope around the new generation of automatically safe reactors. Hinkley was supposed to be the first in a chain of new reactors, with later reactors having decreasing costs due to economies of scale and learning. Time passed, delays accumulated, the situation changed, and I guess they just refused to adapt to the new circumstances, because they'd already spend so much money?
