Rancho Seco.... what an insane story. Didn't know about that. So if your have a bad nuclear project, people are basically stuck with it, unlike replacing solar panels or wind turbines.
I think it's possible that the actual construction of nuclear power plants could become cheap if they were mass produced, but I don't think that's the real problem.
The inherent long-lasting dangers of the fuel and waste are the real cost, and we are still in the first few percent of years where we have to pay for those. In 100 years, the french might be on synthesized fuels from solar and there will be a multibillion budget post dealing with the old nuclear plants that haven't generated anything for years.
Many plants are in the "downpayment of the construction costs" phase and current calculations are made on the idea that once paid for, nuclear is cheap. But that's not true.
There are costs for every nuclear plant that will come due 50-70-100+ years down the line and they are very rarely considered.
The "stuck with it" aspect is what bugs me the most. Once a few politicians today decide to get rich from building nuclear, many, many generations of people are robbed from the ability to make any decision on the matter afterwards. They get stuck with it.
