I agree that it shouldn't be a matter of being for or against nuclear.

The best mix of renewable energy supply of any country is going to be very context dependent. Geothermal, hydro, solar, wind all perform best when they're used in the right location. Nuclear energy is much more expensive per Megawatthour than renewable energy sources, but it's highly predictable.

In addition to the high cost, the construction time of a nuclear power plant tends to be somewhere between 10-20 years. Therefore, it makes sense to find solutions first in grid balancing solutions like mega batteries (for balancing, not long term storage), smart EV chargers, and matching demand better with supply through variable pricing. These are all relatively affordable solutions that would reduce the need for a predictable energy supply like nuclear.

But, if the measures above are not enough or if there are concerns about the feasibility of such measures in a particular context, then analyses might point towards nuclear as a solution as the most cost effective solution.

It's pointless to make nuclear power a polical issue while we're rapidly approaching an irreversible climate crisis. We don't have the luxury to act based on preferences. Policymakers shouldn't view nuclear power as a taboo, but also shouldn't opt to construct one simply to attract voters.
