Because it a a white elephant that allows governments to take longer to pivot to renewables allowing fossil fuel to continue for much longer than needed. It’s playing out in Australia. Australia is never going nuclear. But it allows governments to waste time debating and considering. Even when every forecasting body that isn’t tied to the nuclear lobby laughs them out of the room.
it’s to protect capitalism.
the swedish neoliberal government has defunded existing renewables like wind power and set into law that the government is not allowed to buy back the nuclear plants they are now funding with tax money for private enterprises. with the argument that renewable energy like solar, wind and water will break the economy because it runs in the negative with uncontrollable overproduction but nuclear power is a supply and demand resource based on fuel which will let the private owners maintain artificial scarcity to keep prices stable.
