You are, of course, correct.
But even so, costs are costs. It doesn't matter if you've achieved communism, and are in a moneyless, stateless existance, you need labor and materials to build nuclear, and labor and materials to maintain it (along with other infrastructure).
And, I'm not anti-nuclear; it does make sense to use sometimes, in some amounts. Its just very very costly for what it provides.
But frankly, even only accounting for current tech, wide spread nuclear just doesn't make that much sense compared to renewables + storage and large grids interconnects.
Yeah. I love fallout 1 and 2, and NV is... fine. But at this point, I don't think I'm a 'fallout fan', since I've just had zero interest in the series after hating 3 and 4.
And same thing with elder scrolls, and Morrowind. I just don't like their modern formula, at all.
