Nonsense. The "actual statistics" from the perspective of insurance companies are that if anything bad happens, your insurance company is going bankrupt. It doesn't matter how unlikely that's been calculated to be in some spreadsheet model, no smart insurance company will take that bet.

CO2 tax is still not included into the energy price. If it's done, nuclear will suddenly become much more viable.

My point had nothing to do with energy prices and CO2 tax would not change the fundamental calculus faced by insurance companies.
