Nuclear only costs more because of outdated and intentionally obstructive regulations lobbied for by the oil industry (who also funded environmental groups willing to hate nuclear btw). Even with the massive over regulation of nuclear power in the US, nuclear is STILL more cost effective in the long run, and has only not been done because the risk of the government deciding to shut down their project or add untenable barriers mid construction has been too great to risk it. And don't give me "levelized cost" bs, that is skewed unrealistically against nuclear.
