The problem shouldn't be thought about in this way, or maybe I'm misunderstanding your position. There is no single technology that will solve the issue of climate change (and in this case just limiting our conversation to the production of electricity). The landscapes in large geographical areas like the US are not homogeneous. Solar and wind work great in the Southwest, but not as well in the Northeast. Hydro works fantastically in the South, but not in Southwest (yes I'm aware there is hydropower in the SW, that's not the point). There's questions about base load, storage, peak and intermittent demand, transmission, and so on.

So I dislike these conversations because they seem to be framed as Solar/renewables VS nuclear. When really the conversation should be "should nuclear be part of the solution?" I do believe that the answer is yes (because above factors), but the phrasing matters. This is because it leads to the next obvious and more important question: "If yes, how much?" Clearly a fully nuclear grid is not a smart idea, just like a fully solar grid wouldn't be. But the framing matters. It isn't a "OR" debate, it is an "AND" debate.
