If they said it was going to take 2 years and 1 billion dollars and it stretched out to 3 years and $1.5 billion that is one thing.
Back in the 1970s it was more like 2 years stretches to 9 years and $15 billion and you could blame union workers who never did nuclear work before, the no nukes, high interest rates, etc.
The industry was supposed to come out with standardized reactor types like the EPR, and we have low interest rates, little active opposition to nuclear power, and projects like Olkiluoto-3 are still 9 years late.
Nobody is going to put up billions of dollars unless there is some predictability in terms of cost and schedule. The fear of Fukushima is just icing on that cake.
