New nuclear power plant designs [1] have many intrinsic safety features that largely obviate the old safety concerns that you mention. Anti-nuclear advocates conspicuously ignore these new designs, instead opposing a vision of the nuclear power system that hasn't been current since the 1960s. Argumentum ad Chernobylum just convinces me that the animus against nuclear power comes from aesthetic considerations and not a sober optimization of human welfare against ecological damage.
