In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
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.
