Governments are also looking for efficient ROI when assigning taxpayers money, it helps with other infrastructure projects. Renewables for example, can endlessly buy other renewables. Rather than endlessly supporting just the one. If you can find a single nuclear powerplant in operation that did break-even, lmk because I am unaware of any that has achieved even that. Best-case academic study I've seen for nuclear if they could find a 25% cut to the cost.
