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 Eur...
If we had an energy system owned by the people and not ran for profits, nuclear would be a viable, and probably even the preferred, option. We do not. We're probably going to have to fix that to get a practical and reliable clean energy grid.
Infrastructure in this country is already so heavily subsidized by the federal government (and state, if you live somewhere that actually cares about your well-being) that we're already pretty much paying for it all.
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.
