Is nuclear power so very expensive right now? My understanding is that one of the main drivers behind the huge up front costs of nuclear power is that the builder had to take out a loan to cover the cost of construction before the wheels of regulatory approval started turning. After several years approval would be granted and then construction would still take quite a bit more time. And over all this time that initial loan was accumulating interest - often doubling or more the total capital cost of building a new plant.

But these days interest rates are pretty low and I wonder how much this has affected the price of building new nuclear power plants.
