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.
It’s not that much slower. Our 20a outlets give 2,400w, while yours gove 3000w. And, it’s still faster than a stovetop kettle. Its more that we don’t make hot tea very regularly, while drip coffee was the dominant hot drink for so long.
