The money that will be spent on these new reactors would buy a hell of a lot more wind power than these nukes could produce. But money for renewables would not go into the pockets of right-wing blueblood Swedes, which seems to be what matters to the incoming government.
When the nukes are mothballed early, every kWh they ever produced will, instantly, have actually cost much more than had been reckoned, as the fixed costs are amortized over fewer total.
